Trailers for cars. Technical characteristics of trailers MMZ-81021, MMZ-8176, KrAZ-8138

Hi all! Today I would like to touch on a topic that will in many ways take us back to the past, but at the same time will allow us to remain in the present. After all, we are talking about the MMZ trailer. This is a Soviet-style development that has a long history of existence.

Although the manufacturer’s arsenal included models such as 8113, 81024 and even tractor trailers marked 771 and 771B, the main asset of the manufacturer is still considered to be model 81021. It is this trailer that we will focus on, and also compare its characteristics a little with the more advanced version represented by 81024.

Just looking at the photo, you can understand that you are unlikely to be able to buy a new MMZ. Just recently I came across an advertisement with an offer like selling MMZ in perfect condition. The condition is really good, there are springs, a well-preserved awning and even polished wheels. But now almost all MMZ in this form are alterations, where spare parts were changed, the same lights, springs, etc. were restored.

A little history

The author or creator of such a trailer is the Mytishchi Machine-Building Plant. Hence the name MMZ. This enterprise is an integral component of the association, which is widely known as Metrovagonmash. Even during the times of the Union, the plant produced an extensive range of products, among which there was a place for passenger trailers.

MMZ began producing trailers for passenger cars back in 1972, which was far away for many of you. This was due to the fact that the AvtoVAZ company actively began to fill the domestic market with its cars. You may be surprised, but today there are about 200 thousand still serviceable trailers produced by the Mytishchi plant. With proper storage and preservation, serious results can be achieved. Although MMZ are mostly in demand among those who are interested in buying and converting trailers.

It cannot be said that these trailed vehicles have an ideal body, unique technical characteristics or other undeniable advantages. No. It's just a good trailer of high quality, which was in its time. This allowed them to survive to this day.

Purpose

The first serial trailer from MMZ was the immortal model 81021. It was created specifically for installation on VAZ cars.

Initially, the model was developed as a tow hitch for the VAZ 2101, that is, the Soviet Kopeyka. It is not surprising that the vehicles received similar shock absorbers, identical bearings and even identical wheels. In fact, all the components of the chassis for 81021 were already there. All that remains is to install them on the body and make some modifications. Thus, the plant came up with an ideal partner for Kopeyka, which the owners of these cars immediately took advantage of. They started buying 81021 very quickly and actively.

If we talk about the dimensions of the pioneer, they were 1850x1600 mm. This made it possible to transport all kinds of cargo, making the trailer universal and multifunctional. The design provided for a side with a height of 450 mm and an awning, which was installed on a metal frame. As a result, the total volume of the MMZ was about 1200 liters.

Soon trailers began to be adapted for use on vehicles of other smaller classes. They were intended for cars that were then produced by factories such as AZLK, VAZ and IZH.

Interestingly, the trailer from MMZ, intended for AZLK, received the same design elements as those used on the vehicle itself. For such vehicles, the load limit was set at 135 kilograms. It should also be noted that the GAZ plant produced models for middle-class cars. That is, MMZ made trailers for the then elite and for many inaccessible Volga. The load on the coupling device was a good 50 kilograms, and trailers were allowed to be operated at speeds of up to 80 kilometers per hour.

At one time, 81021 was recognized as a necessary and extremely useful device. This was due to the fact that the trailer could perform several important functions.

Now on Avito and other portals you can find used trailers from different manufacturers, or purchase a new vehicle from a huge assortment. Back then the choice was limited.

But in fact, people did not need a huge choice. They were quite satisfied with the opportunities that MMZ provided them with. After all, with the help of their trailers it was possible to:

• deliver industrial goods;
• transport food;
• transport agricultural products;
• deliver construction materials.

Due to its versatility, MMZ has solved a number of transportation problems. The awning protected from dust and precipitation, the spacious body made it possible to transport fairly large quantities.

MMZ 81021 frame number

Hi all! Today I would like to touch on a topic that will in many ways take us back to the past, but at the same time will allow us to remain in the present. After all, we are talking about the MMZ trailer. This is a Soviet-style development that has a long history of existence.

Although the manufacturer’s arsenal included models such as 8113, 81024 and even tractor trailers marked 771 and 771B, the main asset of the manufacturer is still considered to be model 81021. It is this trailer that we will focus on, and also compare its characteristics a little with the more advanced version represented by 81024.

Just looking at the photo, you can understand that you are unlikely to be able to buy a new MMZ. Just recently I came across an advertisement with an offer like selling MMZ in perfect condition. The condition is really good, there are springs, a well-preserved awning and even polished wheels. But now almost all MMZ in this form are alterations, where spare parts were changed, the same lights, springs, etc. were restored.

Technical specifications

By the way, if you're looking for a frame number, your best bet is to look at the frame itself. Much depends on the specific model. At the same MMZ 81021, the nameplate was installed directly on the body. On other models it is probably stamped on the frame itself. Sometimes nameplates get lost, and the frame becomes covered with rust, making it difficult to find the number. But I think you can find a solution.

If we talk about technical characteristics, then it would be relevant to take model 81021 as a basis. Please note that the vehicle was intended for cars of different classes. Objectively understanding the difference between Kopeika, Moskvich and the same Volga, trailers were made with slightly different parameters.

As a result, approximately the following characteristics can be identified:

• load capacity ranges from 135 to 285 kilograms;
• total weight indicator ranging from 300 to 450 kg;
• curb weight is 165 kg;
• permitted maximum speed 80 kilometers per hour;
• external dimensions are 1850x1600x450 mm;
• internal parameters 1500×1000x380 mm;
• the awning allows you to increase the volume up to 1200 liters;
• track is 1300 mm;
• ground clearance or simply ground clearance here is 250 mm.

Nothing impressive compared to the caravans of our time. But then these were extremely solid designs in their capabilities. So it’s not entirely correct to compare them with current vehicles.

Passport versus actual

The rated load capacity is also called the tested load capacity. In essence, this is a guarantee that the equipment will 100% withstand such an amount of cargo.

Motor cultivator in trailer

To find these values, you can look at the product data sheet, look at the information on the plates on the case, contact the manufacturer, and also find data on the Internet.

There is also an actual load capacity indicator. This is a parameter known only to designers. No one will inform consumers about it. Unless you have a friend who works at a company that produces this equipment, and he will tell you a big secret.

In practice, the actual value is significantly greater than the passport value. But if you violate the restrictions established by the documents, a breakdown will occur; do not expect any repairs under warranty.

Breakdown on the road
There is a difference between the actual and rated carrying capacity - this is the safety margin. And they usually make it quite large. There are several reasons for this:

• in 99% of cases, trailers are overloaded above the norm established in the documents;
• operation on perfectly smooth roads is a rare occurrence;
• few people strictly adhere to the speed limit when driving with an installed trailer;
• Rarely are these vehicles treated with the same care as a car or motorcycle;
• no one plans to replace their caravan every 2-3 years.

Simply put, the safety factor allows caravans to last for decades.

So to speak. Even a trailer up to 750 kg can be loaded with more than a ton. The only question is how far and for how long the equipment can operate in this mode.

Device Features

Finally, let’s look at a few nuances that relate to the design and design of a trailer from MMZ.

The following points can be highlighted here:

• The frame is welded and includes a pair of longitudinal beams with a trapezoidal profile and 3 traverses;
• The total weight of the frame is about 27 kilograms in the classic version. But when repairs and modifications are carried out, the parameters may change;
• The coupling head has a conventional locking mechanism with an overrun brake and an additional safety chain;
• The body is made of sheet steel, the sides are welded;
• The body is connected to the frame with bolts;
• There are wheel compartments and a rubber-based floor cap;
• The sockets necessary for installing the arc under the awning are provided;
• Rear and front collapsible sides appeared after 1986;
• Corrosion protection was achieved using mastics;
• It was only in the early 90s that galvanizing began to be used;
• The awning was made on the basis of tarpaulin fabric and eyelets were installed in it;
• The trailer was equipped with 4 arches;
• Support posts are mounted on the cross member and allow you to block the springs;
• The chassis is made of an all-metal axle with earrings for mounting the suspension and places for mounting wheel-type bearings;
• The suspension is independent and mounted in the middle of the frame. Includes a pair of shock absorbers in springs, a pair of bump stops, conical buffers, a pair of longitudinal bars and one transverse one.

That's actually all I wanted to tell you about MMZ. In fact, the Mytishchi plant became the starting point for MMZ trailers, as they were then produced by many other enterprises. According to some, production was established at 800 factories. Whether this is true or not, I cannot say for sure.

With the commissioning of the VAZ plant, intensive saturation of the private automobile fleet in the USSR began. Many car owners wanted to travel long distances by road. It was for them that special trailers were developed and put into production. One of them will be discussed below.

Total information

One of the first serial products developed specifically for the products of the VAZ plant was the MMZ-81021 trailer. Production started in 1972 and was carried out at the production facilities of the machine-building plant in Mytishchi. The main feature of the trailer was the wide unification of parts with Zhiguli cars, from which the wheels, tires, wheel bearings, and suspension elements were borrowed. Thanks to this, repairs to the vehicle and trailer while on the road could be carried out using the same tool. At the same time, there was no problem with the search and selection of spare parts and components.

An important characteristic of the MMZ-81021 was a unified towing device, which made it possible to operate the trailer with any vehicle. A big plus was the significant dimensions of the cargo platform, which were almost 1.85 meters long and 1.6 meters wide. Due to the sides with a height of 45 cm, it was possible to place a significant amount of cargo, the weight of which should not exceed 135...285 kg (depending on the make of the car). The tarpaulin awning on the MMZ-81021 was installed on special arches, which were included in the standard equipment of the trailer. Due to the awning, the useful internal volume of the trailer was 1200 liters, which was a very good indicator.

Model differences

The trailer could be used by small (VAZ, IZH and AZLK) and medium (Volga) class cars. According to the MMZ-81021 operating manual, the maximum load for machines of the first category should not exceed 135 kg, and for the second - 285 kg.

At the same time, the trailer itself was identical and had a structural weight of 165 kg. Due to proper weight distribution, the maximum load on the coupling device did not exceed 50 kg. The use of a trailer imposed restrictions on the maximum speed of the road train, which should not exceed 80 km/h.

How to increase carrying capacity

The next issue is increasing the carrying capacity.

This is usually done in order to increase the actual parameters. No one will be involved in re-issuing documents or transferring a trailer from category O1 to O2. This is hardly possible at all.

As you remember, overloading a trailer is a traffic violation. So all responsibility falls on you.

There are several ways to increase the load capacity parameters:

• buy a new trailer of category O2 along with the current O1 (the most sensible and legal solution);
• increase the number of spring leaves;
• replace the suspension;
• install a new axle (thick-walled square instead of round);
• install stronger wheels and rims;
• change the platform to a thick metal structure.

Adding springs to a leaf spring suspension (kolkhozim)
Due to such solutions, as well as their combination, actual performance can actually be increased. But remember the responsibilities and consequences.

Tow hitch

VAZ and AZLK cars that rolled off the assembly line never had a standard towing device (towbar). This unit was installed by the owners themselves, purchasing the product separately. For towing the MMZ-81021 trailer, the Mytishchi plant produced two types of devices that differed in the method of attachment to the power elements of the bodies.

One device had catalog number 11.2707003 and was intended exclusively for products from the Tolyatti plant. The second, number 12.2707003, was for “Muscovites”. The ball parts and sockets of the devices were the same. The differences were in the wiring harness from the socket, with the help of which it was integrated into the vehicle’s on-board network.

Competitors

In order to choose a good trailer for a passenger car, the price of which depends on many factors, you should pay special attention to the manufacturer. The durability and practicality of the device depend on the quality of the components and materials, as well as the quality of the device’s painting.

Towbars from the Moscow company MZSA have received good reviews. The model line includes products with aluminum or steel sides, additional protection, large caps, and enlarged sides. The manufacturer also offers specialized designs for transporting boats, boats and other small vehicles. A distinctive feature of this manufacturer is the powder coating method using metal and ceramic inclusions. This provides excellent reliability and safety.

Chassis

To install the wheels on the trailer, there was an all-metal axle, on which there were mounting earrings for the suspension elements and a place for installing the hub bearings. The design of the hub used tapered roller bearings from the Tolyatti “kopek”. The gap in the assembly was regulated by a nut, which was secured against spontaneous unscrewing by jamming part of the belt into a groove on the shaft.

To ensure the technical characteristics of the MMZ-81021, tube-type tires were used, completely identical to the VAZ-2101. When operating the trailer, the pressure had to be maintained within 1.7 atmospheres, which guaranteed a long service life of the rubber and ease of rolling of the trailer.

Other manufacturers

Among the leading trailer manufacturers are . The company specializes in the production of heavy products aimed at transporting yachts, boats, and large industrial equipment. Recently, the model range has been replenished with lightweight modifications that can be equipped with an awning for an MMZ trailer. In addition, the manufacturer claims that, upon customer request, it can supplement the unit with all possible additional structures.

Also popular on the trailed equipment market are models from the Ukrainian enterprise “Kremen” (Kremenchug). The products are distinguished by a high margin of safety, as they are made of high-quality metal, thickened profiles and are equipped with a reinforced frame. The disadvantages of these devices include their heavy weight, which makes the trailer not very convenient. It is worth noting that the range of this manufacturer is limited to single-axle modifications with an average load capacity. Nevertheless, the company remains among the leaders in the relevant market.

Suspension

Suspension elements are installed between the axle and the frame, which reduce vibrations that occur when the trailer moves over uneven road surfaces. The suspension consists of a spring and a shock absorber installed on each side of the axle. To secure the shock absorber housing, there are two reinforcing elements installed between the upper mounting point of the shock absorber housing and the trailer frame. The shock absorber is installed inside the spring.

To protect against sharp impacts during suspension breakdown (full travel of elements), there are conical rubber buffers installed on the frame. They rest against the counterpart on the axle and, due to the deformation of the rubber, absorb the impact energy. There are two longitudinal rods to connect the axle to the frame. There is another transverse rod that serves as a stability stabilizer. All elements are assembled on threaded connections, many of which have safety cotter pins. Over time, these connections rust, and disassembling these units is very problematic.

The structure is based on a welded frame weighing 27 kg. This element is the most critical component of the MMZ-81021 trailer and serves to install the suspension and cargo platform. The frame has a reciprocal towing device that fits onto the towbar ball. All electrical wiring is routed along the frame elements.

Structurally, the part is non-separable and if deformed or damaged, it must be replaced. It is prohibited to operate a trailer with a frame that has cracks or tears. There are three support supports on the front of the frame and the rear cross member, which are used when storing the trailer in the uncoupled state. Additional fixation is provided by wheel chocks included with the trailer.

A coupling device is installed on the front part of the frame, equipped with a chain guard and a spring-loaded crimp device.

Recovery

Repairing an MMZ trailer can be done as follows (the original model was practically coming apart at the seams):

1. Resuscitation begins with careful straightening of the body and sealing all cracks by welding. Next, the diagonals are checked, the sides are pulled together with soft rolled wire and the corners are further strengthened. A couple more amplifiers are welded onto the bottom part. This operation is due to the fact that in the standard version the bottom is equipped with only one amplifier, which is not enough for full operation. As a result, the metal breaks and the bottom simply falls through.
2. You can use improvised means to weld a new body bottom as an additional layer on top of the main element. Several pieces of iron 3 mm thick are quite suitable for this purpose. To begin with, the segments are welded together and then with the main coating. For reliability, the entire structure is fixed with bolts and press washers.
3. We install reinforced springs.

After restoration, the MMZ-81024 trailer was subjected to increased loads (transportation of cement, sand, crushed stone). After 4 months of use - no complaints, even compared to the new model.

Electrics

The circuit includes a plug socket and wires leading from it to the side lights, brake lights and direction indicators. The taillights are borrowed from the ZAZ-966 and installed on the rear of the platform. There is also a platform for attaching a trailer registration plate. There is a separate lighting lantern to illuminate it at night. Two reflective elements are screwed onto the front side, improving the visibility of obstacles when the road train is moving at night. Just above one of the reflectors there is a marking plate riveted indicating the year of manufacture, model and serial number of the MMZ-81021 trailer.

Thanks to the parallel connection of the trailer's electrical system to the vehicle's on-board network, synchronous operation of all lighting devices is ensured. During operation, you should check the condition of the wiring, cleaning oxidized or rusty elements.

Features of operation of the “Bee” trailer

During the operation of the vehicle, shortcomings are identified that need to be taken into account. The "Bee" trailer has a small carrying capacity due to its weak design. And the trailer is not visible to the side mirrors, which creates difficulties when driving. It is not recommended to drive on the highway with an empty body, because it bounces a lot and can roll over. This is due to the air dampers, which do not work on rough roads.

The list of main weaknesses includes:

• Single-row wheel bearings with increased noise levels.
• The hub support itself rusts and is difficult to disassemble.
• The wheels have discs made of thin metal, which quickly fail when the tire is flat.
• Wheels also have a short service life, which is reduced by pumping and overheating, overload and abrasion.
• Over time, play appears in the coupling mechanism.

Loading platform

At the base of the platform there are four timbers of a non-interchangeable design. The platform itself has an all-metal design and is attached through bars to the frame. The fastening elements are bolts and washers. These attachment points often become hot spots for corrosion. The tailgate of products manufactured before 1986 had a solid design. Later, a small folding section appeared in it.

To install the awning, four standard arcs and one 9-strand linen rope with a diameter of 5 mm are used. This rope is used to tighten and secure the awning along the sides of the trailer. Three removable rubber mats are placed on the floor of the platform. When using the trailer, they should be removed to dry the platform floor.

The big disadvantage of the MMZ-81021 trailer platform is the wheel niches, which narrow the useful width of the trailer in the central part. Another disadvantage is the continuous tailgate, which limits the maximum cargo length. Although this problem is not currently relevant, since it is easy to find and rent a truck with any platform length. When the metal of the platform floor is destroyed, it gradually separates from the frame, which can cause the trailer to tip over. During operation, it is necessary to monitor the condition of the fasteners and periodically tighten the connections.

MMZ - trailer for a passenger car: technical characteristics, modifications, repairs

Cars October 12, 2022 The MMZ trailer has been mass-produced since 1972.

The MMZ trailer can be used in conjunction with other passenger cars of domestic and foreign production, which are equipped with a standard towing unit. The towing device in question includes the following parts in its design:

1. Support stands.
2. Body.
3. Frame and drawbar.
4. Chassis.
5. Awning with arches.
6. Alarm system.
7. Electrical equipment.
8. Lock.

The frame of the MMZ trailer is made of steel by welding.

The spars have a trapezoidal cross-section (50/32/25 mm) and are made of steel.

Types and purpose of MMZ trailers

The first serial product manufactured specifically for VAZ cars is the MMZ-81021 trailer. Initially, it was conceived and designed as a towed vehicle for the VAZ-2101 (popularly “Kopeyka”). They have identical shock absorbers, tires and bearings. In short, for the creation of MMZ trailers, spare parts for the chassis were already available, which also met the standards. The dimensions of the MMZ, which were 185 cm in length and 160 cm in width, made it possible to place various loads. And the 45 cm sides and the awning on a metal frame increased the useful volume to 1200 liters.

Subsequently, the trailer was used with small-class cars produced by IZH, VAZ and AZLK plants. Moreover, trailers for AZLK were equipped with structural elements identical to the Moskvich car. They have a load limit of 135 kg. And also trailers for the middle class of the Gorky Automobile Plant, namely for the Volga car, rolled off the assembly line. The direct purpose of MMZ trailers was limited to a load of 50 kg on the coupling device and a speed limit of 80 km/h. The basic prototype MMZ-81021 in those years was recognized as a necessary and technologically advanced device:

• Delivery of small industrial and food products.
• Transportation of agricultural products, construction materials.

The versatility of the trailer solves many transport problems. During the journey, the cargo is protected from dust and precipitation by a waterproof awning. This is much more convenient than transportation in a roof rack on a car.

What does the carrying capacity depend on?

Now let's talk about what affects the carrying capacity of a passenger trailer. There are a few main points here:

• suspension design;
• quality of materials;
• reliability and strength of the axle;
• wheels;
• side height;
• cargo area size;
• tow bar and tow ball.

We are talking about actual parameters. The passports are provided by the manufacturer, and there is usually no doubt about them.

It would seem that since the actual values ​​are higher than the passport values, you can safely load some ATV weighing 450-500 kg onto the platform with a load capacity of 400 kg.

ATV on trailer

Not certainly in that way. Usually inspectors do not pay attention to small differences. Plus you need to go to the weight complex to check.

Another question is when about 1000-1500 kg are loaded into equipment with a capacity of 750 kg and a lifting capacity of about 350-400 kg. This is already a serious excess, as well as a big risk. Firstly, the vehicle may not withstand the load and break down en route at high speed. Secondly, the inspector will definitely notice this. And then a fine cannot be avoided.

Technical characteristics of the MMZ trailer

Compared to modern models, MMZ has low load-carrying capacity, but this is due to the production technology of the 80s and 90s.

• Load capacity 135-285 kg.
• Total weight 300-450 kg.
• Curb weight 165 kg.
• Permissible speed is 80 km/h.
• Dimensions 1.85x1.6x0.45 m.
• Internal dimensions 1.5x1x0.38 m.
• Due to the awning, the volume is 1200 liters.
• Ground clearance (clearance) 25 cm.
• Track 1.3 m.

There is nothing complicated about the device:

The welded frame consists of two longitudinal beams of a trapezoidal profile and three traverses, and weighs approximately 27 kg. The coupling head is equipped with a standard locking mechanism, which has an overrun brake and safety chains.

Re: CAR TRAILER CONVERSION

Good afternoon From a technical point of view, we consider the conversion acceptable. The only remark: what do you plan to do with the total weight, if after conversion the total weight is less than 750 kg, then there is no problem. If more than 750 kg, then the trailer must be equipped with brake mechanisms. Procedure for registration: 1. Take the “application for changes to the design of the vehicle” from the traffic police at the place of registration of your vehicle. 2. Send us copies of documents: 1) Application from the traffic police on both sides with a resolution. 2) Vehicle Passport (PTS) on both sides, 3) detailed description of the work + drawings or photos, if the conversion has already been carried out 4) If you have a technical education, then + copies of these documents 4) Postal address for sending 5) Contact information All documents are provided in the form of copies. Either by email (CONTACTS) or by fax. You can also send documents by letter to the address: Moscow, st. Yablochkova, house 21, building 3, office 1D, 2E or personally by the owner or representative. 3. Refurbish. 4. The following documents will need to be provided to the traffic police: 1) Application for changes to the design of the vehicle, 2) Conclusion on the possibility of converting the vehicle (you receive from us), 3) Declaration of the volume and quality of work performed. 5. At the traffic police, you submit the trailer for instrumental inspection and fill out a diagnostic card. A note about the changes made is made in the PTS and a new vehicle registration certificate is issued to you.

Regarding the homemade chassis - at the moment there is a legal vacuum in Russia in this area; registering a homemade vehicle is very problematic. The conversion path is much simpler.
