3x3 all-terrain vehicle: Ural tricycle, light three-wheeled carakat, do-it-yourself, swamp vehicle, homemade all-terrain vehicles, how to make

Purpose of a 3x3 all-terrain vehicle

The vehicle in question is designed to overcome any off-road conditions. The tricycle will go through forest paths, sand, mud, ice, shallow water and shallow snow.

ATVs are popular among hunters and fishermen.

Owners appreciate the increased cross-country ability, compactness, and maneuverability of the unit.

Such modifications are of interest to residents of the outback and villages. All-terrain vehicles will confidently overcome country roads, reaching speeds of up to 60 km/h. Moreover, the price of such a vehicle (especially a home-made one) is an order of magnitude lower than its automobile counterpart or ATV.

How to make low pressure tires

If you want to make an all-terrain vehicle of a similar design, you must first familiarize yourself with how to make tires - low-pressure tires. It is advisable to use old truck tires as a base, and it is extremely important that their wear is small. Making such tires yourself is quite simple, just follow the following algorithm of actions:

1. Clean the tires from dirt.
2. Cut them along the inner perimeter, which will allow you to dismantle the wire.
3. Mark rectangles near the cut and cut them out using a construction knife.
4. Remove the wire and secure the tire.
5. Peel the tire from the outer layer.

After such manipulations, the master will have a chamber at his disposal from which he can make a wheel, creating a tire frame. To do this, you will need to weld rims for low-pressure tires, for example, from an aluminum basin, grind the frame and put it on the prepared inner tube. Such wheels can be installed on a homemade all-terrain vehicle made on the basis of a walk-behind tractor.

Tire benefits

Such wheels are very popular when designing all-terrain vehicles, which is due to a wide list of advantages that distinguish them from other possible options. Among them, it is advisable to mention the affordable cost, which will significantly reduce the cost of manufacturing the model.

The wheels are perfect for moving over various types of terrain, allowing them to be used in different regions and weather conditions. There are other advantages of such elements:

• light weight, which can significantly improve the dynamic characteristics of the finished vehicle;
• due to the large area, it is possible to successfully move through sand, snow and other difficult terrain;
• no negative impact on the ground, which allows the use of an all-terrain vehicle for traveling through fields.

An all-terrain vehicle with such wheels can be used as a low-power tractor to perform simple tasks, which makes it a universal solution.

Recommendations

The joints of the frame parts must be reinforced with gussets made of sheet steel. To make the design more correctly, it is advisable not to limit yourself to simple drawings, but to use large-scale models.

It is immediately necessary to provide attachment points:

• engine;
• shock absorber;
• seats;
• fuel tanks;
• pendants

It is advisable to install the engine so that there is a free flow of air around it. This rule is important even when water cooling is used.

You should definitely take care of the appearance of the vehicle. An elegant, attractive appearance is often created through chrome surfaces and individual parts. To make using a tricycle more comfortable, it can be equipped with fog lights, speaker systems, and so on.

The front part is often made on the basis of silent blocks. The rear main rail is equipped with fasteners that support the body. It is advisable to use tractor generators as a source of energy in electric tricycles. The gearbox and axle shafts can be bored to size on a good lathe. The installation of an electric motor capable of pumping additional air will help prevent overheating of cylinders made of aluminum.

Craftsmen never cease to amaze with their ideas; each homemade product is unique and one of a kind.

Advantages of a tricycle

1. Diagonal hanging is not possible. All 3 wheels are always in contact with the surface, unless of course the trike is upside down or lying on its side.
2. Less weight with all the consequences: slightly better cross-country ability, lower consumption, better dynamics. All other things being equal, of course.
3. Simplicity of design.
4. Better cross-country ability when compared with rear-wheel drive four-wheel vehicles. I could be wrong here, because... on the one hand, pushing one steering wheel is easier than pushing two. Plus less overall weight. On the other hand, with four wheels, the rear drive wheels already follow the track from the front ones, which can sometimes improve cross-country ability. Therefore, not everything is so simple here.

If we take, for example, an all-wheel drive tricycle and an all-wheel drive ATV with similar characteristics, then I’m almost sure that the quad will be more passable.

That seems to be all there is to the advantages of the three-wheeled layout, now let’s look at the disadvantages.

Fork

The length of the fork is determined by your project. If you want to make a long front fork, this trike is suitable for flat roads and long rides. A more aggressive driving style will require a shorter length. A tricycle from Izh, photos of various mods of which can be found on amateur forums, may even have a trunk located above the front wheel. Of course, in terms of cross-country ability, trikes are not competitors to ATVs, but for trips to the country, garden or fishing, the work invested will more than pay off.

General technical specifications

Homemade tricycles are mainly made on motorcycle frames or structures hand-welded from a metal profile. Wheels from trucks or tractors are used as wheels. The transmission, brakes, steering rod are formed from spare parts of domestic and foreign cars or motorcycles.

For comparison, the table shows the parameters of 2 serial domestic tricycles.

Pros and cons of homemade all-terrain vehicles

Homemade tricycles are not inferior to many factory analogues in terms of performance. At the same time, the costs of manufacturing, repair and maintenance are lower.

Three-wheeled karakat with planetary engine

The article is compiled based on forum materials, link to source

Some information on the caracat, although everything is clear from the photographs, but it may still be interesting. The engine is from an IZH Planet motorcycle, the left cover with a fan is from an SZD disabled person. The standard electrical equipment was replaced with Voskhodovskoe, which does not require a battery and is much more reliable since it has a chroll sensor instead of cams.

UAZ differential and two long UAZ axle shafts. The axle shafts are shortened since the karakat karakat would turn out to be very wide. The original hubs are cut and pressed from Moskvich ones, since the wheels are made on the basis of lighter Moskvich wheels.

The motorcycle wheel disk is halved and a disk for the Bel-79 is made on its basis. In general, two sets of wheels were made, one based on Bel - 79 for mud, one based on tubes for swamps. Upon completion, an unexpected thing emerged: the tube wheels turned out to be somewhat heavier. This year the summer was dry and on the factory wheels we drove through the swamp without any problems; I haven’t “put on” the tube ones yet.

The frame is reinforced with gussets, at the bottom at the engine mount and in the fork mount area. A bronze bushing is inserted into the fork mount for strength, since even without such loads as in the swamp near IZH, the bearings break in this place. The body is made of sheet aluminum and aluminum corner with rivets:

The price of the karakat turned out to be very decent, but this is because a lot had to be redone during the work, since there was no experience in manufacturing just such devices. Various technical problems were also solved along the way. The design mainly used only new parts and materials, which is why the price was high. The device is being modified as it goes into use; it has been out through the summer and half of the fall through mud swamps, etc. no problems so far. Below are photographs of the making of this all-terrain vehicle.

The caracat's cross-country ability is excellent, it rushes through the swamp as it should, the engine is high-torque and even with a load it moves confidently through a completely off-road swamp. Very maneuverable and well controlled, of course not like a regular motorcycle, but quite normal and not heavy. In the north of the Omsk region and in Tyumen it is very rare to see a four-wheeled carakat; three-wheeled ones have been tested by time, and they are simpler in design than four-wheeled ones, less iron and components, which means more reliable.

Why do you need a velomobile?

The velomobile has characteristics that a regular bicycle does not include in its functionality:
You can sit comfortably on the velomobile by installing a soft, comfortable chair; Another huge advantage of a velomobile is that when riding it, the lion's share of the muscles in the lower body sways. And these are legs, hips, and abs. If you do everything correctly, you can include other muscle groups in action to look beautiful and fit. A velomobile is also needed by those who burn with happiness, accelerating at incredible speeds.

The most important thing at this point, right, is to install all the structural details. In addition to the above-mentioned advantages of this type of transport, a velomobile will also come in very handy for people who like to ride around the city or beyond, breathing deeply in fresh air and freedom.

Types of homemade all-terrain vehicles

Lightweight all-terrain vehicles, also called carakatas with low-pressure tires, are in high demand as they are excellent for off-road driving. They compare favorably with standard SUVs because they are able to move in the complete absence of road surfaces and in rough terrain. Such products are distinguished by their simple design and wide functionality, which makes them an ideal vehicle for use in hard-to-reach areas of the country. There are several varieties of this kind of product, which allows everyone to choose the best option for themselves. Among them it is worth mentioning:

• boat-type pneumatic passages, which are distinguished by their affordable cost and simplest design. They are equipped with a suspended power unit, which allows them to move around small bodies of water;
• tracked products, excellent for moving through swamps and reservoirs with a lot of vegetation. It is much more difficult to manufacture such a structure, since this will require selecting a suitable tracked drive;
• swamp vehicles on low-pressure tires are the easiest to manufacture and the most promising type, which can be created from scrap materials at minimal cost.

Since the latter type is the easiest to assemble, it is advisable to familiarize yourself with it in more detail. Similar all-terrain vehicles operate on the same principle, which involves the use of large wheels for off-road movement. There are several subspecies of caracats of this variety. Among them it should be noted:

• all-wheel drive models that involve the use of a gearbox and chassis from a car. It is distinguished by the presence of all-wheel drive, as well as a sealed hull made on the basis of a boat;
• tricycles - products with 3 wheels, assembled on the basis of an unnecessary motorcycle, most often domestically produced;
• all-terrain vehicle made from a motorized stroller - involves placing the power unit under the seat, using a motorized stroller as the basis, as well as car parts;
• models where the basis is passenger vehicles or ATVs.

Before manufacturing, it is extremely important to decide on the type of all-terrain vehicle, its model, and also to obtain suitable drawings, which will allow you to avoid mistakes during the self-assembly process.

All-terrain vehicle characteristics

The actual characteristics of an all-terrain vehicle on low-pressure tires directly depend on the components and elements used, as well as the type of device. It is strongly recommended to use power units of sufficient power, which will allow you to overcome even difficult obstacles without any problems.

Battery

The battery for your tricycle must be installed under the driver's seat - for this purpose a special frame is created, located above the engine. This way, everything important about your vehicle is in one place. You should also consider making the passenger seat behind the driver's seat. Not only does it allow more people to ride at the same time, it can be attached with saddlebags that will completely enclose the engine and battery, making your trike complete.

All-terrain vehicle based on the Urals

At the preparatory stage, drawings and a diagram of the future tricycle are being worked out. In the variant under consideration, chain transmission is not provided.

The unit is suitable for 15-inch alloy wheels, which are heavier than homemade analogues, but more reliable and have a beautiful appearance.

After choosing the final concept, they move on to turning the parts of the all-terrain vehicle.

Tools and Supplies

The frame from the Ural motorcycle, converted to accommodate the installation of a car rear axle, was chosen as the base. You will also need the following items:

• ICE type Lifan (6.5 hp);
• variator from a scooter;
• tarred fiberglass;
• moped generator;
• muffler with wide cross-section;
• metal corner 32 mm;
• tires out the Shishiga wheels;
• conveyor belt.

The instrument is traditional. You will need a lathe, yews, a set of keys, screwdrivers, a gas welding machine, and measuring devices.

Main stages of rework

The process of creating a three-wheeled all-terrain vehicle can be divided into several stages:

1. Preparing a variator from a 4-stroke 150 cc scooter. This part is convenient because it is easy to adjust working and coupling speeds. These modifications are mounted on motors with power up to 14 hp.
2. They begin to create the rear axle of the all-terrain vehicle, including preparing the site for the automobile bridge, manufacturing cones and flanges.
3. The front fork is widened and adjusted to fit a wide rim.
4. The seat is made of plastic, lubricating the prepared mold with wax and then laying fiberglass in several layers.

Making odorishi

On a light three-wheeled carakat they put “strippings” from the tires of a GAZ-66 or Ural (Lapot) car, as well as medium-sized tractors. The tires become lighter, while a new tread is cut onto the old rubber, which is responsible for reliable grip when driving on snow and mud.

It’s not difficult to make wheels for an all-terrain vehicle with your own hands. Process steps:

1. Using a construction knife, a cut is made around the perimeter of the tire to remove the wire.
2. Mark rectangles for the future tread and cut them out.
3. The wire is removed with a hook and a hand winch or a screwdriver.
4. The peeled rubber is peeled off.
5. Remove unnecessary layers until the frame remains.
6. The discs are welded to the plates, and the surfaces are sanded.
7. Put the headband on the frame.

Engine and transmission

The wheeled all-terrain vehicle in question was equipped with a Lifan engine, modified for installation on a tricycle. A moped generator and a larger cross-section muffler were also installed. The standard carburetor did not perform well, which is why a tractor starter was installed.

This approach made it possible to increase the power of the karakat by almost 2 times.

The variator works great, in the 2nd range it makes it possible to slip and drift. In mode 4, the unit starts off smoothly, accelerates to 50 km/h, and at high speeds loses stable control. A unit from Honda City, Oka, Zhiguli is suitable as a transmission box. The gearbox is mounted on the vehicle frame and is coupled to the rear axle using a cardan drive.

Final improvements

At the final stage, the reliability of the assembly and the operation of all components are checked. The seat and body are painted, oil and fuel are added. If desired, fenders, mudguards, light and signal elements are mounted.

Stages of karakat development

Conventionally, we can distinguish the following stages on how to assemble a floating caracat:

1. Creating a Frame
2. Making a pendant
3. Creation and installation of wheels
4. Engine and systems installation

Caracat frame

First of all, you need to choose a suitable frame for installing all the necessary equipment and units on it. It is desirable if it is a walk-behind tractor belonging to the medium or even heavy class of equipment.

In fact, even the most “advanced” karakat is nothing more than a homemade all-terrain vehicle, which is usually mounted on a frame with four (4x4) or even three wheels (tricycle). The choice of the number of wheels depends solely on the design features of the intended vehicle and the previously developed design.

The wheels must be “shod” with high-quality low-pressure tires; the structure is powered by an installed powerful internal combustion engine.

Suspension

The suspension of a walk-behind tractor will require special attention and precision on the part of the developer. At this stage, in addition to the suspension itself, the master will need to make a rear axle, which is done exclusively with his own hands.

Rear axle drawing example

The suspension provides a special design made of two separate parts connected together by hinges. In this case, the spars must mate with each other, for which a steering bushing is used. Ultimately, it is possible to form independent front and rear suspensions.

The main condition is to achieve exceptionally high suspension independence, because It is this indicator that allows the all-terrain vehicle to be operated in the most unpredictable places, guaranteeing the safety of the structure.

Maneuverability and cross-country ability should be the primary factors that you should pay attention to when making a homemade caracat design from a walk-behind tractor.

Suspension

It doesn’t matter whether you make a tricycle with your own hands from an Izh or any other motorcycle. You will have to remodel the front wheel suspension anyway. After all, the distribution of forces in a tricycle is very different from that observed in a regular motorcycle. To do this, you will need two pairs of consoles, as well as two powerful springs - if possible, try to get helicopter or airplane springs, but springs from passenger cars can also be used if necessary. The consoles need to be connected to each other by levers, through which the axle of your front wheel will pass. Naturally, this is not the only way - there are a large number of ways to make a tricycle with your own hands. Drawings are available on the Internet (one of them is in our article), but this method is one of the most effective.

Ural Hercules - factory Ural tricycle

The Irbit Motorcycle Plant has released a three-wheeled modification in its model range for transporting cargo up to 500 kg. The model is called “Hercules” and moves well both on city roads and off-road. The sides of the tricycle are also removable and this allows it not to be limited in the size of the cargo it transports. Hercules is a truck that does not require a category “C” license.

Ural Hercules

Technical characteristics of the Hercules tricycle:

• Dimensions: 335x150x115 cm
• Ground clearance: 185 mm
• Weight: 500 kg
• Fuel tank capacity: 19 l
• Maximum speed: 70 km/h
• Engine capacity: 750 cc
• Power: 45 hp
• Engine type: opposed 4-stroke with two cylinders
• Generator: 500 W
• Electrical: 12 V
• Transmission: 4-speed, with reverse gear
• Tires: 6.45 and 13 inches

Reclining

A separate category of tricycles that are used as racing bicycles. This design allows you to ride in a reclining position or lying on your back.

The specific appearance attracts attention. This “adult” tricycle develops greater speed than standard models

Semi-recumbent bicycles are divided into:

- according to the intended purpose (sports, recreational and record racing);

— by the nature of the drive (with rear-wheel drive, with front-wheel drive and a movable carriage, with front-wheel drive and a fixed carriage);

- by wheelbase size (short, medium, long);

- according to the height of the seat above the ground: with a high, medium (to the ground 40 cm) and low (15-20 cm) seating position.

— semi-recumbent three-wheelers can be single or double (tandem).

Result

The trike turned out to be quite suitable for use. Of course, there cannot be special dynamics with such power, and it is not needed. As I already said, the average speed in the forest rarely exceeds 25-30 km/h, and even then on a relatively flat surface. The power of this engine is enough to confidently maintain a speed of around 20-25 km/h in 4th gear. Then there just isn't enough momentum. I'm thinking of increasing the maximum speed with the help of stars. Now with 15 teeth on the motor and 35 teeth on the gearbox, the speed is as follows:

• in 1st gear - about 3-4 km/h;
• on the 2nd - 6-8 km/h;
• on the 3rd - 14-17 km/h;
• in 4th - up to 24 km/h.

As for traction, there is plenty of it. The trike pulls away easily even in third gear. It’s possible in fourth, but there’s already a load on the engine and clutch.

In general, the power of this engine is quite enough for confident off-road movement, and thanks to the good “lowering” and reverse gear, the cross-country ability has increased noticeably.

Three-wheeled models of 3x3 all-terrain vehicles

3-wheel swamp vehicles are not as common as ATVs. This category is represented by units on low pressure tires. Vehicles are made by hand or produced in small series. Among the latest versions, several manufacturers can be noted.

All-terrain vehicles Barkhan

Karakat is designed to carry cargo and 2 people. The compact amphibian effectively overcomes rough terrain with different slopes, swampy areas and sections covered with silt or peat, with a thickness of 300 mm. Shallow rivers and lakes will not become an obstacle for the specified vehicle.

The Barkhan 200 modification floats well due to the air in the tires, which have a low weight and increased ground clearance. It is possible to additionally tow a trailer up to 270 kg. The frame is a tubular, welded configuration, the front suspension is a fork-lever with springs and shock absorbers. The rear shaft supports are fixed rigidly, the disc brakes are hydraulically driven.

Vasyugan models

The three-axle Vasyugan 3WD SUV has a 3x3 wheel arrangement and is equipped with switchable all-wheel drive. The equipment is assembled to order, taking into account the wishes of the potential buyer. The all-terrain vehicle can be equipped with low-pressure tires or similar ones with a special tread.

The engine is a 150 cc 4-stroke internal combustion engine, the transmission is a CVT, the start is electric or kick starter. The model's load capacity is up to 200 kg.

Pakhus Veles

The all-wheel drive tricycle is designed for use on rough, swampy terrain and other off-road conditions. A powerful engine complete with electric start, CVT, and wide LP tires is responsible for cross-country ability. Capacity - 2 people, maximum speed - 45 km/h.

The Veles 3x3 all-terrain vehicle is presented in 2 modifications. They differ from each other in tire dimensions (25 and 26 inches). The motor is a QMJ157 type engine with reverse. The power of the 4-stroke air-cooled engine is 9.5 hp.

Ataman

The Ataman all-terrain vehicle differs from its analogues in the type of engine. A multi-purpose motor is used as a power unit, mounted on various types of equipment, including generators and cultivators. Vehicle weight is 110 kg, with a load capacity of 180 kg. The package includes a trunk and a device for towing a trailer weighing up to 250 kg.

Three-wheeled modifications of Ataman:

1. Classic and AWD with an ATV engine, reverse gear.
2. Power with motors up to 15 hp
3. Diesel with engines 10-12 hp.

All-terrain vehicles Shogrash

A floating all-terrain vehicle is designed to transport people and cargo on different road surfaces and water surfaces. Number of people - up to 4, cargo weight - 200 kg, towed trailer - 250 kg. The tricycle on ND tires is equipped with a quad engine with forced atmospheric cooling. Upon request, it is possible to install a liquid jacket and more powerful motors.

The basic configuration includes a gasoline engine with reverse and electric starter. The speed limiter is 45 km/h, the fuel tank capacity is 12 liters, and there is a CVT. The steering linkage is of a motorcycle type, which simplifies the control of the pneumatic stroke.

Zubr line

The tricycles of the Trike series of this manufacturer are equipped with 4-stroke internal combustion engines with 1 or 2 cylinders, with a power from 9 to 24 hp. (270-680 cc). The motor is rigidly mounted on the axle and gearbox, the clutch is fixed on the crankshaft, which ensures maximum torque transmission.

The all-terrain vehicle is equipped with a manual transmission with 4 modes, and there are 2 gearboxes for the rear wheels. The main advantage of the design is the absence of chains in the running unit.

The vehicle has permanent rear-wheel drive and can overcome off-road conditions without any problems due to the correct weight distribution and differential, which transfers the load to the wheel opposite to the steering wheel. Low pressure tires, equipped with 2 or 4 rubber cord layers.

Tricycle with Chinese engine

Hi all! As you already understood from the title, this article will focus on a tricycle with a Chinese Forza engine (similar to Lifan). Initially, the tricycle was made from a Ural motorcycle, which is discussed in detail in the article of the same name. Here we will consider the process of installing the engine, connecting it to the Zhiguli gearbox, preparing the mount for all this, and related issues. So, let's begin. Why is all this needed?

The answer to this logical question follows from the shortcomings of the native Ural engine and transmission. Namely:

• constant problems with carburetors and the ignition system;
• tendency to overheat;
• high gasoline consumption.

• no reverse gear;
• Speed ​​is too high in first gear.

It seems like little things, especially considering that the trike has never seriously let us down, but it would have been better without them.

Plus, it was just interesting to cross a Chinese engine with a classic gearbox. It was interesting what would come of it. And it turned out quite well.

A few words about the engine

Initially, it was planned to install exclusively a 15-horsepower Lifan with a reduction gearbox and automatic clutch. But the practice of using a trike in the forest has shown that the average speed of movement rarely exceeds 25-30 km/h. Due to the fact that all the roads are overgrown or swamped, traveling at high speed is either impossible, uncomfortable and even dangerous. Therefore, it was decided to go with the Lifan engine with a power of 6.5 horsepower, also with a reduction gearbox and automatic clutch. It cost 2 times less than the 15-horsepower one, plus I had a little experience in operating this particular engine and confidence in its reliability. An acquaintance drove a motorized towing vehicle with such an engine for several seasons under very harsh use. What I wasn't sure about was whether 6.5 horsepower would be enough for a tricycle weighing about half a ton. Looking ahead, I will say that it was quite enough.

Forza engine - analogue of Lifan

It so happened that the seller did not have the 6.5-horsepower Lifan with the required shaft diameter for the gearbox, but there was a FORZA engine similar to it, which, in addition, cost a thousand rubles less. The characteristics are the same, the dimensions are the same, time will tell in terms of quality and reliability, fortunately there is a one-year warranty. Everything (motor and gearbox) cost about 9,500 rubles.

It was immediately decided to use the box from the classics. We found an old but working 4-mortar on Avito for only 1,200 rubles. These boxes are very reliable, I think it is the most durable component of the tricycle.

How to connect the engine to the gearbox

Everything is simple here, with the help of stars and a chain. I had to tinker a little with the star on the box. The splined part from the Zhiguli clutch disc was machined for it and simply welded into the star. In this way, the star was easily put on the input shaft of the box, which, in addition, was inserted into an additional bearing outside the box.

Connecting the engine to the gearbox

In our case, the box shaft rotates in the opposite direction, because The bridge was upside down and I didn’t want to re-weld the fastenings. Plus, with this rotation, the layout turned out to be the simplest and most compact. As for the cardan, on the side of the bridge there is a regular crosspiece, and on the side of the box there is a native Zhiguli rubber coupling. Everything works great.

Lightweight three-wheeled karakat

The author has been making light three-wheeled caracats for about two years now. Initially, the author was going to make a three-wheeled off-road moped, but then he decided to make it for sale and accordingly build on the wishes of clients. Therefore, a similar machine was born, not large in size, but with a powerful engine. The weight of the all-terrain vehicle is under 200 kilograms, which makes it easy to transport and store.

Materials and parts used to build this all-terrain vehicle model:

1) Lifan 6.5 liter internal combustion engine. With. 2) Gearbox from a Honda City 3) CVT from a scooter 4) Resin fiberglass 5) generator from a moped 6) wide-section muffler 7) corner 32 mm conveyor belt

Let's take a closer look at the stages of all-terrain vehicle construction.

To begin with, the layout of the all-terrain vehicle was thought out and the main development paths for the vehicle were determined. The author immediately abandoned the idea of ​​a chain drive, more for reasons of reliability. It was After determining the basic concept, as well as selecting materials, the author began turning work on the parts of the all-terrain vehicle.

A four-stroke variator from a 150cc scooter was prepared. It is convenient because it is easy to adjust both the operating speed and the clutch speed. As a standard, such CVTs are installed on engines with power up to 14 hp. so there shouldn't be any problems. Here is a photo of the variator and drive pulley:

Then the author began work on the rear axle of the all-terrain vehicle, as well as turning the cones:

Started manufacturing flanges for wheels:

A gearbox from a Honda City was used as a gearbox, although it was originally planned to install one from Oka:

Then the gearbox was installed on the all-terrain vehicle frame:

The Lifan engine was used, which was slightly modified for use on a three-wheeled karkat:

Here is a picture of the machine on which most of the turning work on the parts of the all-terrain vehicle was carried out:

Wheels and rims from BMW were installed:

A generator from a moped and a large cross-section muffler were also installed:

The original carburetor performed poorly, so a tractor starter was installed, which almost doubled the power of the all-terrain vehicle. The variator works great; in second gear the all-terrain vehicle is capable of slipping and even drifting. The maximum speed for second gear is 40 kilometers per hour. In fourth gear, the all-terrain vehicle starts off very smoothly and accelerates well, but at speeds above 50 km per hour, it becomes difficult to control, so the author did not test maximum speeds.

Soviet analogue of Mikuni 22 mm, there is a button on the bottom of the carburetor, which is convenient when starting the all-terrain vehicle:

The all-terrain vehicle frame was made from 32 mm angle iron. a meter of angle weighs about 1.2 kilograms, and a meter of square pipe 25 by 2 mm weighs 1.1 kilograms. That is, if desired, it would be possible to reduce the weight of the frame, but the author decided to make the frame more reliable and strong.

The carburetor is used from the starter. It starts up perfectly, works well both at minimum and maximum modes, but in the transition it was acting up and it took two whole days to get it right:

Gear box

When you make a tricycle from the Ural with your own hands, you definitely need to take into account where exactly the gearbox will be located. You already understand that the engine itself will be off the axle, behind the seat, between the two rear wheels. At the same time, make sure that it is attached as securely as possible in at least three places - especially if you plan to perform various tricks, as described above.

As for the gearbox, it is better to install it on the left side of the steering wheel, since your right hand will be occupied most of the time. It is unlikely that if you take the engine and gearbox from a car, you will be able to make a design that is convenient enough to change gears without stopping driving.

Also don't forget that you need to take care of connecting the box to the motor, which is a bit more difficult considering that it is now located a little further from the box than it should have been in the original. But if you're trying to figure out how to make a tricycle with your own hands, you always need to be prepared for these kinds of surprises and difficulties.

DIY low pressure tires

Tires of this type visually resemble huge pillows that support the entire structure. The degree of grip in such wheels allows the vehicle to be passable on any off-road terrain. Depending on the design features, such tires are divided into the following types:

1. Arched. They are 5 times larger in size compared to a standard wheel, and have a thickness of up to 700 mm. The pressure in them is like in a regular ball - 0.05 MPa. Installed exclusively on the drive drive.
2. Wide-profile. They are distinguished by an oval design and pressure up to 2 times lower than standard. Most often used in lifting vehicles.
3. Toroidal. They are manufactured in tube and tubeless versions and are highly popular among car enthusiasts.
4. Pneumatic rollers, having lugs to improve cross-country ability, and stiffening ribs, giving the entire structure stability and strength.

The cost of factory-made low-pressure tires may be unaffordable for many car enthusiasts. But for your own all-terrain vehicle, it is quite possible to make such a wheel yourself. The work is performed in the following order:

1. Selection of source material, for example, agricultural or aircraft tires, as well as other types of industrial transport.

2. The tread is cleaned, washed and dried, after which the desired patterns are drawn to create your own design, as well as to remove excess wire and rubber.

3. To remove excess wire, the inner part of the wheel is trimmed and the cord is removed using a winch.

4. Excess rubber is also removed with a winch, making cuts around the circumference, and securing them to the cable with pliers, carefully pulling them and cutting them with a knife.

5. After removing the tread layer, the surface is cleaned with sandpaper.

6. Disk assembly. To do this, use a standard disk cut in half, or welded from plates and pipes, and then carefully polished to prevent damage to the camera.

7. The tire is pulled onto the rim and secured with belts or a fire hose, and then inflated. The wheel is ready.

What type of tread should I choose for an all-terrain vehicle?

To select the right type of tread for an all-terrain vehicle with low-pressure tires, you need to consider the following factors:

1. The protector must have the ability to self-clean. This property is especially important for using an all-terrain vehicle in harsh and wetlands.
2. When using an all-terrain vehicle on peat bogs, choose tires with low and shallow terrain, otherwise if their top layer breaks, the grip will be insufficient for full movement.
3. When used in snowy areas and on sandstones, tires with a rare pattern are chosen.

We make a wood splitter

Among other things, you can make a wood splitter a walk-behind tractor To do this, you will need to grind a cone on a special machine, as well as a thread. After this, the finished cone must be mounted on a shaft that has suitable bearings. Then you need to install a flange at the end of the shaft, as well as a sprocket. It can be taken from a motorcycle wheel.

You can fix the cone on the shaft using a bolt. After this, between the motor and the shaft itself, you need to install a spacer made of pipes, as well as a pair of nuts. This will help tension the chain. In order to make supports for the shaft, you can take supports from Zhiguli cars. The motor must be taken from the walk-behind tractor . With the help of such a redesigned design, you can easily cope with splitting firewood.

Motor winch

This homemade walk-behind tractor can be made at home. This will help save money. For manufacturing you will need a motor, a frame, and both shafts: upper and lower. The motor for this can be taken from a chainsaw. In addition, it is necessary to make drawings, and then begin assembly.

In addition, factory walk-behind tractors can be converted at your discretion into other designs, for example, a trike or a circular scooter.

Thus, if you show a little ingenuity, as well as get some parts and make high-quality drawings, you can use the walk-behind tractor as the starting material for the manufacture of a large number of devices that will become indispensable assistants in the household at different times of the year. However, it is important to strictly follow the assembly instructions and follow all recommendations.

To learn how to convert a walk-behind tractor into a mini-tractor, watch the following video.

What is needed to make an all-terrain vehicle

When planning to make an all-terrain vehicle with your own hands, you need to make sure in advance that you have the materials, drawings, and the appropriate tools. For most connections, especially frames, it is recommended to use a welding machine to ensure long service life and high structural strength.

Materials

It can be convenient to use a walk-behind tractor as the basis for an all-terrain vehicle on low-pressure tires, which will significantly reduce costs and simplify the self-assembly process. You will need to find several elements at once, without which the construction of a karakat will be impossible:

• frame of suitable shape and size;
• rear axle, which will be used to mount the rear wheels;
• a seat for the driver, as well as means of protecting him from dirt and precipitation;
• lighting devices that will be required for driving at night.

Adult 3 wheel bicycle - classification

Folding. It is very convenient to store, especially in urban environments, as it takes up very little space.

Electric bike. Equipped with an electric motor, so it is convenient for the movement of elderly people and people with disabilities.

Folding three-wheeled electric bicycle. This is an excellent option for older people living in small apartments or houses, since this model is not only convenient to store, but also easy to ride.

Reclining. This model has wheels and pedals located at the front and is operated in a lying position. It combines a regular tricycle and a recumbent bike to provide a comfortable ride. There are single and double options.

Recumbent three-wheel tandem. It has many settings that will ensure maximum riding comfort, including a 24-speed transmission for uphill and downhill driving. It is equipped with a seat that provides a comfortable seating position.

With a low frame. This makes it easier to get on the bike, which is suitable for people with mobility impairments and women.

Double for walking. In this model, the seats are located parallel, which allows you to have a conversation with your partner while leisurely riding in the fresh air. The pedals can be pedaled by both cyclists at the same time, or in turns.

Three-wheel tandem. This model of a bicycle for adults differs from the previous one in that the seats in it are not located parallel, but along the length of the bike, one behind the other. They can be controlled both together and separately.

Three-wheeled chopper. The models are made in an exclusive stylish version with graceful lines that are different from all two- or three-wheeled bicycles. They look unusual and beautiful.

Is it possible to assemble a tricycle for adults with your own hands?

On the bicycle market you can buy a ready-made kit, which includes an M2 rear axle, a Uk6 rear axle and a kit for a three-wheeled six-speed bicycle with and without a differential, and assemble a tricycle for adults yourself.

These kits are so versatile that the rear axle design is ideal for tricycles with different wheel diameters and frame sizes and can be converted to any bike.

The only thing to consider is that the drive of a tricycle for adults without a differential is usually only available on the right wheel. Therefore, when turning right, there is a slight tilt to the left. Typically, tricycles use standard components other than the frame, so there are no problems with repairs and spare parts.

Do-it-yourself three-wheeled swamp vehicle

Homemade swamp vehicle, made by yourself: photo and description of the homemade product.

This all-terrain vehicle is built for travel in off-road conditions, mud, slush, snow and swamps; the vehicle can easily overcome, and it should be taken into account that the swamp vehicle is assembled from spare parts from domestic auto-moto equipment.

The design of the swamp vehicle is shown in the photo:

To build the all-terrain vehicle, part of the frame from the Izh motorcycle was used, however, it had to be radically altered in order to install the rear axle from the Lada.

The homemade product is equipped with an engine from a motorized stroller and an additional gearbox. There is also a reverse gear.

The wheels are worn off from a Ural Lapot truck. The wheels are homemade.

There is a cardan transmission on the rear axle of the tricycle.

A homemade swamp vehicle that moves well in deep snow, mud and other off-road conditions.

Frame

It will be easier to make an Izh tricycle with your own hands if you have experience in welding and understand the design of motorcycles or cars. The frame will have to be completely manufactured from scratch, have a pre-designed shape and structure. Usually the calculation is made in such a way as to exclude breakdowns and places with vulnerable structures, so that the trike can travel hundreds of kilometers without maintenance.

Strengthening is achieved by welding corners and additional pipes

so that the fork does not vibrate. The basis of the transmission can be taken from a walk-behind tractor or combine harvesters. If you want to get a traction type Izh Planet tricycle, it is better to use sprockets in a ratio of 2:1, i.e. 50 and 25 teeth respectively.

Homemade all-terrain vehicles from a Ural motorcycle are easy

Today, all-terrain vehicles based on the Ural motorcycle have become very popular. Even without modifications, this motorcycle is capable of traveling off-road. Since roads are not always of excellent quality, and you have to get around somehow, several mechanisms with increased cross-country ability were invented. One of them is based on the Ural motorcycle.

The all-terrain vehicle will move on three wheels with reduced pressure. It will be based on the units of this motorcycle. The same applies to the frame, to which an additional structure will be added. One of the connections is located in the upper shock absorber mounting area, where the motorcycle frame bends.

The main part of the additional structure is a 0.42 mm curved pipe. Rigidity is achieved through a strong triangle made of the same material, additional bracing and braces at the upper level of the frame. The complexity of the design makes it possible to evenly distribute the weight of the all-terrain vehicle between the wheels and add another passenger seat.

The seats remain unchanged and are attached in the same way. You can replace the handles with a stiffer version for ease of fit. Between the last two seats there is a box in which it is convenient to store a first aid kit. Instead of a battery, you can install an oil canister, and the gas tank is located at the rear of the frame.
