All-terrain vehicle from Oka, built with your own hands: drawings, photos and description.
This all-terrain vehicle is built on the basis of the Oka compact car. We invite you to take a look and get acquainted with the design of the homemade product.
Spare parts and materials used:
- Engine and gearbox from Oka.
- Bridges from UAZ.
- Transfer case from Niva.
- Wheels from Kraz.
- Steering and springs from Volga.
- Square pipe 50*50*2.5 mm - 20 meters.
- Sheet metal.
The photo shows drawings of the all-terrain vehicle frame. The frame is welded from square pipe 50*50*2.5 mm, 20 meters of profile were used for the frame. It turned out to be durable and light, the weight of the frame is about 50 kg.
I installed the springs from Volga, initially the springs contained five leaves, but two leaves were removed and, as it turned out later, it was in vain, it was necessary to leave all five. Shock absorbers from Niva.
The photo shows homemade adapter for connecting the UAZ cardan with the Niva transfer case. It’s done like this, take 2 UAZ and Niva flanges, cut off the working part of the oil seal from the Niv one, downsides We join the flanges together and weld them together, we get an adapter.
I painted the frame and bridges and installed the engine. The differential in the box is welded, the Okovskaya “grenade” is cut off and a flange for the Nivovsky cardan is welded to it.
I installed a Volga steering wheel, it’s a little hard to steer, and over time I’ll need to install a hydraulic booster.
Since the landing of the wheels on UAZ bridges is a little narrow, I decided to make wheel disks with an offset to move the wheels further away from the body. This is necessary so that the turning radius of the front wheels is sufficient.
The tires were taken from Kraz; the peeling process was carried out using a chainsaw, which was used to cut strips. I peeled it off with an electric hoist and trimmed it with a utility knife.
One day on the road, both CV joints on the wheel side fell off. The reason for this is not known, but now I always carry spare ones. There may be additional load due to wheel offset, or there may simply not be enough strength for severe conditions. And so the all-terrain vehicle has been in service for several years and so far there have been no more serious breakdowns.
In rural areas, a common problem is the lack of roads. This problem is especially acute during winter, when even the usual crossings are covered with a layer of snow. To organize traffic even in such a period, you can make an “Oka” car out of your forces.
Thoughtful solution
Since in rural areas you often have to navigate difficult terrain, many people want to buy an SUV. Alas, such cars are quite expensive, so you need to know how to make an all-terrain vehicle from the Oka. To create it, they use improvised means, which include spare parts from broken cars and motorcycles.
Among the most popular options for “folk” crafts are “station wagons” based on low-pressure pneumatics or air cushion. The use of crawler tracks is also common, but they are more suitable for snowy areas. Creating an SUV based on the Oka is economical profitable solution, since there is no need to purchase expensive components.
All-terrain vehicle on low-pressure tires
This design is based on an invention that uses a body that is located on a breakable frame. This solution significantly strengthens the design of the product. All wheels are installed with your own hands as drive wheels, so they can even overcome swampy terrain.
Based on Oka engines, the production of so-called karakat engines is also very popular. They stand out for their increased cross-country ability thanks to wide-format tires. This complements the advantages of pneumatics, because it does not destroy the grass cover.
Using Tracks
These “station wagon” options are most popular among fishermen and hunters. from "Oka" have increased cross-country ability in water bodies and wooded areas. Their body is usually made of a box structure, which reaches a length of 3 meters. It is light in weight, so in places where deep traces of a person remain, vehicles penetrate into the quagmire only 10 cm.
Correct execution of such a device is possible only with reliable calculations. This is especially true for the chassis, which should be in contact with the ground by 1.4 square meters. m. The speed of the product is 45 km/h. You can also find hovercraft all-terrain vehicles. They have more than the tracked all-terrain vehicle from the Oka, and also do not require a chassis.
Stages of creation
To acquire the design of an SUV, you will need to carry out the following manipulations:
- Finding a basis for vehicle. Using a motorcycle frame is quite suitable for this. The brand doesn’t matter, it all depends on the financial choice, as well as off-road preferences. This indicator is most developed in IZH motor vehicles.
- Creation of the rear axle and suspension. To do this, you need to use a strut that connects the side members. All this is complemented by a strut and steering bushing, which as a whole form an independent rear suspension. It is recommended to use just such a suspension, because it will provide the product with the necessary maneuverability in difficult places.
- Installation of wheels. In practice, such an all-terrain vehicle based on the Oka is equipped not with the wheels themselves, but with their cameras. They come from trucks and are attached to the suspension using a hub. Stability is complemented by special tapes that wrap around the wheel. As a rule, cameras from cargo trailers are used. This solution increases the reliability of the trip.
- Providing torque and mounting the engine. Such procedures begin to be done after installing the frame and suspension. In addition to the motor, you will also need to install a brake, clutch and exhaust system.
When the entire list of work has been completed, it is necessary to test the device for functionality. If errors are identified, they must be corrected. As practice shows, an illiterately made all-terrain vehicle or swamp vehicle from the Oka can create a danger to others.
Possible nuances
Despite its advantages, this technique has its drawbacks. The fragility of cameras often causes trouble low pressure. Of course, due to the missing differential, the vehicle does not require frequent servicing, but the presence high pressure in large wheels reduces their maneuverability. Also, due to the size of the wheel system, there is a problem with flying dirt, because it is quite difficult to cover them with wings.
Practice shows that pneumatics have poorer maneuverability than the Oka all-terrain vehicle on tracks. The choice of materials used for the design and type of future vehicle directly depends on the purpose of use. More and more people from suburban and rural areas prefer the creation of such structures, since converting the Oka into an all-terrain vehicle is, first of all, financially profitable.
A homemade all-terrain vehicle from Oka is profitable and convenient, because the device can be repeatedly modernized and improved. In different weather seasons, its design and characteristics can be changed to adapt them to weather conditions terrain.
Creating a homemade all-terrain vehicle is a common practice in suburban areas where it is not possible to purchase one. But it is important to consider design features and approach the creation of such a machine with all responsibility. Negligent performance of work can create a risk to the life of the driver and others.
Homemade all-terrain vehicle on caterpillar tracks, made from Oka.
Small car "Oka", not for the village best option, in off-road conditions, to travel on country roads, you need a good SUV.
One craftsman solved this problem quite in an original way, he made his Oka into a powerful homemade all-terrain vehicle on caterpillar tracks. We invite you to familiarize yourself with the process of building an all-terrain vehicle shown in the photo.
And here are the mounting points for the engine and suspension of the all-terrain vehicle.
I made an all-terrain vehicle frame from profile pipes.
I started making suspension on balance beams with torsion bars.
Rollers for tracks and drive stars were made from wheel rims.
Then, the Oka body was installed on a homemade frame.
I would like to clarify that the tracks are taken from a snowmobile.
And this is what the interior of the all-terrain vehicle looks like, instead of a steering wheel there are track control pedals, brakes are installed on the leading track stars, turning is carried out by braking one of the tracks.
This is how the all-terrain vehicle from Oka turned out, on caterpillar tracks. The homemade vehicle reaches a speed of 30 - 40 km/h and can easily move through snow and mud. You can additionally install a blade and clear snow in winter. The all-terrain vehicle can tow car trailer or pull out a stuck car. In general, an excellent homemade product for a villager.
