Hello, dear friends! Today I invite you to consider with me and discuss in the comments the UAZ Trailer. This trailer is designed for use on UAZ 2151 vehicles, which previously had the index 469. This single-axle UAZ trailer is a good representative of its generation. It has one axis, so be sure to consider this before purchasing.
If you need a two-axle option, you can take a drawing and assemble a homemade trailer. Don’t forget, due to two axles the weight increases, reinforced springs are required and many other nuances appear. What am I telling you? Just read and compare two-axle and single-axle trailers.
Yes, today a huge range of all kinds of trailed vehicles are produced for cars. But you need to be able to navigate this diversity.
Selection and purchase
Someone decided to buy a car from conservation or simply use ads on Avito or other resources to find a used towed vehicle. The question of buying from conservation is quite interesting. That's the essence of it.
There is a military facility where vehicles were stored (mothballed) for a long time. This is not military equipment, since the army does not sell it to civilians, but vehicles that you and I can operate. Sales from conservation are affordable and in many ways profitable. That’s why people often keep special watch and find out where the sale will begin in the city of Astrakhan, or the Kemerovo region will announce the availability of vehicles for conservation.
You can easily find such advertisements yourself. Everything is sold there with documents, they offer reasonable prices and a number of other advantages. Although we may somehow talk to you separately about this. It seems to me that the topic of conservation vehicles, other vehicles and their sale will be interesting and useful for you.
UAZ has a fairly large number of vehicles in its product range. Let's name the most basic ones:
- 542;
- 3303;
- 3151 (469);
- Farmer;
- Hunter;
- Patriot.
The single-axle trailer itself from UAZ has the index 8109. It is not necessary to buy it for all the cars presented above.
For some craftsmen, it will not be a problem to use Krepysh trailers. Moreover, alteration of the hub is not necessary here. You can operate Krepysh with UAZ wheels and hubs, or with your own standard ones. Only in the second case will it be necessary to rearrange the hubs and increase the ground clearance, that is, ground clearance. There you go.
Choosing a trailer for an SUV
The most iconic and widespread is the UAZ-8109 trailer, which is produced by the car plant itself. Most other manufacturers take its design as a basis, sometimes making some changes to it. In addition, in some places you can find an old GAZ-704 trailer, which was developed for use with the GAZ-69, but is also perfect for UAZ. Very often, the sale of such trailers is carried out in organizations that collect military equipment from conversion. Military models often have “convoy” sealed kungs, illuminated bridges, brutal appearance and more durable construction. True, when buying from a conversion, the frame and chassis often require serious restoration. You can also look for trailers for UAZ in villages, where they are often sold in almost perfect condition, and their prices are ridiculous. But in this case, you may need not only restoration, but also restoration of documents.
Patriot with standard trailer
Almost every trailer for this SUV has a leaf spring suspension. The smoothness of the ride is also enhanced by two additional shock absorbers. Sometimes you come across spring versions, but they are not as heavy-duty, although there is an opinion that they are more preferable for transporting fragile cargo. To transport ATVs, snowmobiles and other equipment, two-axle modifications of trailers with larger diameter wheels that are suitable for UAZ are usually used. But when purchasing them, it is worth remembering that if the curb weight exceeds 750 kg, you will have to open the “E” category, and you won’t be able to carry them off-road.
The main advantage of the UAZ-8109 trailer is its short wheelbase and high ground clearance. Pulling it out of the mud is not the slightest difficulty. In addition, there are special hooks at the rear, which can be used to rescue the trailer from severe off-road conditions in reverse.
High fenders prevent the wheels from blocking due to accumulated dirt. The trailer has a standard awning, convenient racks and a full set of lighting equipment. In short, the design of the UAZ 8109 is the most preferable.
Design features of UAZ 8109
Let's start with the description of the UAZ trailer we are considering. You can watch a video about it, look at various photos to better understand what we are dealing with and what I am talking about in general.
And for those who are not interested in buying a ready-made car trailer, there are a number of useful recommendations on how to make a car trailer with your own hands. If so, just follow the links and read. Next, be sure to read about trailer registration issues.
What do we have in the case of 8109? Let me first offer this description:
- The trailer is made of a frame based on durable metal. The metal platform is welded to this frame;
- The 8109 has a tailgate that greatly simplifies loading and unloading procedures;
- When the load is placed on the loading platform, it is positioned so that the vertical force from the coupling loop to the towing hook does not exceed 490 N or 50 kgf;
- If you intend to operate a trailer without connecting it to the vehicle with a safety chain, forget about your intentions. You can't do that;
- The welded frame consists of a pair of side members, a drawbar and cross members;
- A pair of towing hooks are installed on the rear of the frame;
- The drawbar has a welded structure and is integrated with the frame;
- A removable hitch loop and safety chains are mounted on the front of the drawbar. We read separately about the features of the coupling device;
- In a horizontal position, folding support posts are used to hold the drawbar;
- To attach the coupling eye to the drawbar, use a connection using 3 bolts.
This concerns design features.
Next we move on to the technical parameters. There I will tell you about the main figures that relate to the UAZ 8109 car trailer.
Requirements for trailers for UAZ vehicles
A trailer for SUVs of the UAZ family must have high ground clearance and a wheel diameter corresponding to the wheels of the UAZ tractor. Standard models for passenger cars are not suitable for this role, since the wheels on the trailer must not only be of the appropriate size, but also suitable for use in poor traffic conditions. Therefore, in traditional models of trailers for Russian SUVs, such as the UAZ-8109 and even the GAZ-704, the manufacturer included the possibility of operation on any roads and terrain, and without any improvements to the factory characteristics.
Specifications
When the vehicle is equipped with a load of 500 kg, the total weight is 750 kilograms;
The permissible maximum cargo weight for transportation on 8109 will be 450 kg;
The equipped trailer together with the awning here is 300 kg.
Now about the distribution of road loads through the wheels of trailer 8109:
- at full weight the figure is 750 kgf or 7357 N;
- with the vehicle equipped - 270 kgf or 2649 N.
No less significant for some buyers will be the value of the forces from the coupling eye to the towbar:
- for a trailer with a full weight the force will be 490 N or 50 kgf;
- for a equipped vehicle the indicator will be 295 N or 30 kgf.
If you decide to attach such a trailer to your car, then you are allowed to accelerate with it no more than 75 kilometers per hour. But who actually follows these recommendations?! Remember, this is purely a matter of your safety and responsibility to other road users.
If you are interested, I also suggest telling you about the lighting of this single-axle UAZ trailer.
Suspension
The UAZ car trailer with index 8109 uses two longitudinal semi-elliptical springs, which work together with a pair of telescopic hydraulic shock absorbers.
The spring includes 9 leaves. Their ends are mounted using pins and rubber bushings. One spring has a length of 1000 millimeters with a sheet thickness of 45 millimeters.
Trailer for UAZ. Types and purpose of trailers
The popular UAZ SUV, produced in Ulyanovsk, can rightfully be considered the most durable Russian car. It earned this characteristic not only due to its cross-country ability, but also its carrying capacity. Even an old “Bobby” (UAZ-469) can easily transport two adults and 600 kilograms of luggage. The UAZ vehicle is capable of more, but for this you will need a trailer. It will add at least another half ton to the total carrying capacity.
Car paint thickness gauge: which one to choose, how to use
The shock absorbers here are of a double-acting type, telescopic and hydraulic. They were unified with the shock absorbers of the 3151 car from UAZ. You do not need to make any specific settings and adjustments.
The wheels are stamped and made of steel. The rim is deep and one-piece. Their dimensions are 6Jx15. And the tires are six-ply tube type, size 215/90 and R15. The manufacturer tried to unify the trailer hubs with UAZ 3151 car hubs. Although some people like to deal with wheels of a larger radius. It's a personal choice for everyone.
When adjusting the torque of the hub bearings, be sure to carefully control it. It would be a good idea to take a suitcase with tools and get a torque wrench. If you do not tighten it properly, the trailer will be subject to constant impacts during operation, which will cause the bearings to fail in a short time. If you tighten it too tightly, then the bearings will begin to heat up excessively, all the lubricant will leak out and the bearing will become unusable.
Electrical part
It's no secret that to connect a trailer to a car you will need two main electrical components:
