The cross-country ability of such an all-terrain vehicle is not satisfactory, however, there are a number of disadvantages.
Too hard to manage. With a heavy load due to the design of the all-terrain vehicle, even the hydraulic booster can not cope and control all-terrain vehicle quite difficult. The author thinks about limiting the displacement of the frames along the semiaxis.
the original version of the engine from the VAZ was too heavy, and a new one of 15 horsepower, too weak for such an aggregate, besides because of the loud noise (the engine is quite noisy under load), it does not make sense to use this all-terrain vehicle with such an engine on a hunt. All animals scatter another kilometer before the entrance to the hunting site.
Tires from Gas 66 are too small to properly row in the water, perhaps it will be decided by installing a boat engine.
The tipping frame design is quite complex and takes up a lot of space, as well as weight.
And of course, as expected, drum brakes when used in mud quickly fail. Definitely needs to be replaced with disk.
Thus, the all-terrain vehicle needs modernization, the main of which is weight reduction and the selection of a normal engine.
As conceived by the author, this all-terrain vehicle should be able to not only overcome mountainous terrain, but also water obstacles. The all-terrain vehicle will have four-wheel drive. The author devoted a special place to the reliability of the all-terrain vehicle, a rigid roof and a safety arc in stock.
Inside the all-terrain vehicle there is a stove and a couple of places for sleeping and relaxing. There is swap suspension from the exhaust.
What parts and materials were used in the construction of the all-terrain vehicle:
1) The internal combustion engine VAZ, which was subsequently replaced by a Chinese version with a capacity of 15 liters. from.
2) Tires from Gas 66 lightweight.
3) Pipe 60 mm
4) GP from Gas - 71
5) Hubs from Gas-53
6) bridges from MAZ
7) Wheels VI-3
Regarding the mass of the all-terrain vehicle, we can immediately say that it will not be the easiest. Since the author wants to use an exclusively automatic transmission, this will immediately throw half a ton, taking into account the engine. The frame should be strong enough and the weight will be from 200 to 300 kilograms. To this we add the weight of the casing, the interior and as a result, the total mass of the all-terrain vehicle will be 1500-1600 kilograms, which is quite a lot.
Let's consider in more detail construction all-terrain vehicle.
It was very well explained why the choice fell on the automatic gearbox.
Only with such a box can you skid normally at speed, and the wheels will at least somehow move such a heavy car in the water.
Since the terrain is mountainous, the likelihood of burning the clutch is very high, then the automatic transmission, which solves this problem, shows its advantage.
Automatic transmission, just more convenient, especially on the ascents and descents from the hills.

After the basic installation of the elements, the author began preparing the engine, namely, the regulation of the valves.
Below is a photo of the work carried out with the engine. The problem with the valves was clarified after a conversation between the author and the previous owner of the unit. It turned out pretty simple, the camshaft was changed.
After such revelations, the adjustment of the valves went in the right direction.
Regarding the dimensions of the all-terrain vehicle, it will turn out about 140 cm by 70 by 70.
Wheel from VI-3:
Then the author decided to tackle the all-terrain vehicle disks. Two ZIL disks were seized with iron and joined into one barrel, then the ends were welded, the middle was cut out and everything was sent for turning for processing.
Below is an example of manufacturing a disc in this way:
Another all-terrain vehicle diagram from a different angle:
The subframes and calipers from the Subaru were used:
All sizes were taken and the author began to manufacture disks. To do this, he made a 500 to 500 cylinder from a sheet of metal 2 mm thick, and he inserted two 19-inch disks into it. The advantages of this method are the cheapness and simplicity of the design.
Other photos of all-terrain vehicle elements:
A sketch of the hub was made. the meaning of the sketch is that the gray guide fastens help to fasten the wheel weighing 100 kg, plus studs in the hub. All this is screwed onto 6 nuts. design feature is that you can remove the tire without removing the disc itself, which is quite convenient given the not weak weight. That is, the work is quite feasible for one person.
A sheet of metal was cut from a cardboard stencil and welded at one end to a disk. Then it’s a matter of technology, carefully heating the metal with a blowtorch, folding it around the disk, helping the sledgehammer to give the desired shape. But unfortunately there was a macaw of marriages, in particular due to insufficient heating or inattention, a pair of such blanks turned out with ribs.
The axles of the wheelbase will be made under load, taking into account the mass of one and a half tons plus a margin of about another half ton.
Thus, having made the necessary calculations, the author came to the conclusion that the diameter of the pipe for the axis should be at least 60 mm.
The drive circuit was decided to be closed:
The author also decided to use the hub from Gas 53, its advantage is that it is able to withstand loads of up to five tons, which includes not only the mass of the all-terrain vehicle, but also the load from acceleration when meeting an obstacle. Therefore, despite the fact that they weigh a lot and overload is obtained at 150 kilograms in comparison with similar ones, four such hubs were nevertheless installed. Thus, the chassis of the all-terrain vehicle received a triple margin of safety.
The engine of the machine, it was decided to install across. There is one problem, the 2lt engine, which was in the hands of the author, does not have an automatic transmission, so you have to try and merge it with a non-native automatic transmission. The author didn’t even want to consider a variant with mechanics, since you need to manage such a heavyweight with both hands and there is no desire to be distracted by the gear lever.
The author saw the possibility of facilitating control in the GP from Gas - 71, although it again will increase the mass of the all-terrain vehicle by a hundred extra pounds.
Bridges from MAZ were used and turned, due to availability.
