An all-terrain vehicle containing a sealed body in which there are: a passenger compartment, an engine compartment, a cargo compartment, as well as tracked vehicles located on both sides of a sealed body, a power plant, a suspension, a swivel mechanism, and a drive transmission.

The disadvantages of the all-terrain vehicle are:

1. There is no way to overcome difficult sections of the road where it is impossible to provide traffic due to the caterpillar mover, for example, when building a car in a quagmire, mud, ditches and so on, as well as short steep climbs;

2. It is not possible to operate the machine with a trailer;

3. It is not possible to transport the machine to the place of operation without loading it onto the vehicle;

4. The ride is not ensured during the passage at high speed of roughnesses of the supporting surface with a height of up to 350 mm;

5. There is no possibility in a short time to carry out repairs of the power plant and the balanced suspension system;

6. High curb weight of the machine and the cost of scheduled maintenance;

The problem is solved in that in the proposed universal off-road floating tracked vehicle for transport operations in especially difficult road and climatic conditions, comprising a sealed enclosure, body elements, safety cage, trunk, drive sprockets, tow hitch, suspension shock absorbers with springs, track rollers, levers, supporting rollers, brackets for fastening the rigid coupling, adjusting bolts, locking bolts, track rollers, electric winch, articulated tracks, front lighting, engine compartment, rear passenger seats, passenger compartment, driver's seat, steering wheel, dashboard, front console, gearbox control lever, onboard planetary gears, powerplant with manual transmission, front passenger seat, rear passenger seat lighting devices, tensioner, plug, clutch release pedal, brake pedal, accelerator pedal.

New significant features:

1. are provided for transporting the machine to the place of operation

- an easily removable rigid coupling (drawbar) designed for coupling the machine with a standard trailed device of an all-wheel drive passenger car, as well as a plug for connecting to the passenger car's electrical system.

- easily removable tracks and pneumatic track rollers on which the machine relies on a rigid hitch during transportation;

2. overcoming difficult sections of the path where it is impossible to provide traffic due to the caterpillar mover, for example, when the car is stuck in a bog, dirt, ditches, etc., as well as overcoming short steep climbs, it is provided with an electric winch mounted on the front of the machine with a steel rope wound around the drum and remote control;

3. A standardized tow hitch is provided at the rear of the machine to enable operation with a car trailer;

4. The smoothness of the course when unevennesses with a height of up to 350 mm pass at a high support surface are ensured by the use of pneumatic track rollers mounted on an energy-intensive link suspension with a stroke of more than 350 mm;

5. The reduction of downtime due to a malfunction is ensured by the use in the design of the machine of parts commercially available by domestic engineering and a power plant represented by a standard engine with all systems and a VAZ transmission;

6. The curb weight and the cost of scheduled maintenance of the machine were reduced due to the use in the design of a lighter and less costly maintenance unit presented by a full-time engine with all systems and a VAZ transmission. The second constructive solution, which allowed to reduce the weight of the car, was the use for thermal insulation of the sealed body of the machine, as well as the engine compartment and exhaust pipe of an ultra-thin, ceramic, liquid heat insulator of the brand “Corund”.

The listed new essential features are sufficient in all cases to which the requested scope of legal protection applies.

Identified distinguishing features in conjunction with the known provide a technical result.

It is possible to transport people and goods in places with dissected terrain (scouring, tubercles, screes), weak supporting surfaces (snow, swamp, peat bog) and many water barriers, overcome mainly by swimming, transportation on public roads to the place of operation is carried out on a rigid coupling passenger car tractor.

Universal off-road floating tracked vehicle for transport work in especially difficult road and climatic conditions works as follows

Before towing to the place of operation, they attach a rigid hitch (drawbar) on one side to the brackets 11 of the universal off-road floating tracked vehicle for transport operations in especially difficult road and climatic conditions (hereinafter referred to as the car), on the other hand, to the towing device of the towing vehicle. The truck tractor is installed on the parking brake. The tracks 16 are removed from the chassis of the machine. To do this, the locking bolt 13 of the tensioner 30 is loosened. By rotating the adjusting bolt 13 counterclockwise, the tensioner 30 is moved to the rearward position corresponding to the minimum tension of the track 16. Then the track 16 is sequentially removed from the tension roller 14 supporting the rollers 10 and the drive sprocket 5. When both tracks are removed, the car tractor pulls the car at a distance equal to the length of its body. Free from the track rollers 8, the tracks 16 are rolled up and laid in a specially provided space between the front 28, 21 and rear passenger 19 seats. A plug 31 connects the control of the rear lighting devices 29 of the machine to the electrical system of the towing vehicle. Towing is carried out according to the rules of the road.

At the place of operation, the tracks 16 are put on the machine, performing all the operations to remove them in the reverse order, the tension bolt 12 of the tension device 30 is set to their required tension and fixed with the locking bolt 13. The machine is installed on the hand brake, the plug is disconnected and the rigid coupling is cordoned off from the tractor vehicle and brackets for fastening the rigid coupling 11.

A driver’s workplace equipped with driver’s seat 21, steering wheel 22, dashboard 23 mounted in the front console 24, gearbox control lever 25 and accelerator pedals 34, brake 33, clutch 32 off, provides complete control of the machine and meets the requirements safety precautions. The location of the controls is identical to that of the passenger car, which greatly simplifies the training of the driver.

To start the movement, they start the machine’s engine, depress the clutch 32 clutch pedal, the gearbox control lever 25 engages first gear, smoothly releasing the pedal 32, and engages the clutch. The torque through the gearbox by means of the SHRUS transmission mechanism is transmitted to the drive sprockets 5 mounted on the output shafts of the onboard planetary gears. Drive sprocket 5 engine torque translates into the translational motion of the track 16, the machine comes into motion. Gear shifting occurs similarly with cars.

To rotate the machine, turn the steering wheel 23. The hydraulics in the lateral planetary mechanism, which drives the inner gear relative to the radius of rotation of the track 16, brake the sun gear and brake the shaft with the drive sprocket 5 mounted on it, and the larger the rotation angle the steering wheel 23, the higher the braking force on the shaft of the drive sprocket 5. As a result, there is a turn in the desired direction, and the angle of rotation of the steering wheel 23 is adjusted company, right up to a turn in place around the middle of the area of the supporting spot internal to the radius of rotation of the track 16.

The large area of the contact spot of the tracks 16 with the supporting surface makes it possible to move the machine on slightly bearing soils. If the bearing capacity of the supporting surface is insufficient, and the machine, despite the relatively low mass, begins to sink, then the sealed casing 1 will not allow it to completely sink, providing the displacement necessary to keep the machine afloat even in water. The use of modern ultra-thin liquid brand “Korund” for thermal insulation of body 1 of the machine made it possible to maintain the temperature regime required at the driver’s workplace and passenger seats, while minimizing the weight of the machine’s structure.

The mover of the machine during the movement of the swim are tracks 16.

In the mode of movement of the car over rough terrain, there is a high probability of encountering irregularities, for example, stones, and if their height does not exceed 350 mm, then the passage of such sections is possible at high speed without damage to the car and discomfort for passengers. When the caterpillar runs onto such an unevenness, the first to hit and extinguish most of it is the pneumatic track roller 8, then the remaining part of the impact energy is absorbed by the independent, link suspension of the track roller 8, with a stroke of more than 360 mm. Four such support rollers 8 are sequentially installed on each side of the machine.

To overcome sections of the path where the movement of the car due to the caterpillar mover is impossible, for example, its slipping, cross hanging of the car or a vertical obstacle with a height of 500 to 1500 mm, it is equipped with an electric winch 15 with a control panel and a steel cable wound around its drum mounted in the front body parts.
