The technical result from the application of the utility model is to expand the performance of a universal vehicle due to the fact that it has a more compact design, can be used on public roads, without limiting the speed, within acceptable limits, and also confidently stay on water. 4 ill.

Description

The utility model relates to transport engineering, in particular to movers on a caterpillar track.

Known wheel caterpillar mover (US Pat. No. 2119438, IPC B62D 55/08 of 06/03/1994) containing a caterpillar chain with tracks in the form of pneumatic pillows, covering the leading and driven sprockets, spar and support rollers.

A disadvantage of the known technical solution is that it is technologically complicated, this limits the scope of its use.

Usage - pneumatic tracks for tanks, self-propelled guns, tractors, all-terrain vehicles, cars for riding on the tundra, snow, ice, marshy soil, desert and water movement.

The disadvantage of previously designed pneumatic tracks is the desire to follow the design of metal tracks both in shape and in the number of "tracks", all chassis are expensive, require large and frequent repairs and, due to their inefficiency, have not been developed. Work resource is limited.

Known wheel caterpillar mover (RF patent No. 2534166, IPC B62D 55/08 of 11/27/2014) containing a caterpillar chain with tracks in the form of pneumatic cushions, covering the drive and driven sprockets, the spar and support rollers, the caterpillar chain is made in the form of a flexible endless inextensible tape, on which the axis of rotation of the paired pneumatic wheels mounted on the lower side of the chain on the road surface from the outside and on the drive support rollers located at a short distance from one another on the bottom of the spar, are mounted on the inside her hand.

A disadvantage of the known technical solution is the complex management, difficult turning to the side on public roads.

The technical task is to create a universal mover with all-terrain characteristics for road vehicles, expanding their capabilities, ensuring increased vehicle speed over rough terrain, driving comfort and improving performance.

The technical result from the application of the utility model is to expand the performance of a universal vehicle due to the fact that it has a more compact design, can be used on public roads, without limiting the speed, within acceptable limits, as well as confidently stay on water, successfully to overcome wet and swampy areas as an all-terrain vehicle.

This is achieved due to the fact that in a universal vehicle propulsion device containing a caterpillar element, according to a utility model, the caterpillar element is made in the form of two closed fabric sealed shells with tension rollers located inside each closed fabric sealed enclosure and mounted freely on the bearings of the base plate , in each corner of which the axes of the rotating rollers are installed, the vehicle is equipped with sliders, guide rails and a pendulum torsion suspension, sliders getting around the edges of each envelope to be movable in the guide rails, providing a free rolling sheath tensioners are installed inside the shell, and the shell has sealed in the interior space of the vehicle between the wheels.

The main differences of the utility model from well-known technical solutions:

- a universal vehicle with all-terrain properties and the possibility of operation on public roads, without limiting the speed, within the permissible;

- a compact device, under the vehicle’s body with automatic installation in the working position to overcome difficult sections of the road and off-road;

- transfer to the folded state of the shells without the use of physical force, by turning off the pneumatic system;

- after passing obstacles and off-road sections, the body remains in an aesthetically satisfying state (without lumps of dirt and stains);

- the longitudinal arrangement of two shells filled with air, acting as a pontoon, allows the vehicle to confidently stay on water.

In FIG. 1 shows a universal vehicle, general view.

In FIG. 2 - the same, top view.

In FIG. 3 is the same, section AA in FIG. 2.

In FIG. 4 - the same, torsion bar suspension with an attachment element.

Positions indicate: shell 1; slider 2; guide runner 3; tension roller 4; pendulum torsion bar suspension 5; vehicle 6; roll 7; skating rink 8; base plate 9; axis 10; drive drum 11.

The device comprises a wheel mover, which is located inside a closed fabric hermetic shell 1 (section aa). The wheel mover comprises a support plate 9 mounted freely on bearings. In each corner of the plate 9, axles 10 of rollers 8 rotatable by the drive drum 11 are installed. The casing 1 is designed as a conveyor belt. The sliders 2 are installed on the edges of the shell 1 (section BB), with the possibility of movement in the guide rails 3, providing free rolling of the shell 1. The tension rollers 4 inside the shell 1 in extreme positions provide operability due to the pendulum torsion bar suspension 5. The bands of the shell 1 are placed in the interior of the vehicle 6 between the wheels. Rolls 7 perform the function of supports. They limit the vertical movement of the mover to the upper position and protect the shell 1 from mechanical damage.

The shell 1 becomes operational when creating air pressure from the pneumatic system of the vehicle. This condition is sufficient to overcome water barriers. Shell 1 can serve as a pontoon. When the vehicle passes difficult sections of the road or off-road, the propellers are brought into working condition by creating air pressure in the rollers 8 and switching the rotation drive. In swampy and moistened soils, the shell 1 fills the free space between the rollers 8 of the rotating mover. The mover 8 advances the shell 1, driving the vehicle. The wheel mover during rotation forms due to differently variable loads, the soil between the rollers, which is the supporting mass for moving the vehicle. We get the effect of advancing the tape of the shell 1, which is applicable in tracked movers with tracks.

The utility model will allow tanks and any other military equipment to move on snow, swamp, water, desert, tundra, etc. with great speed, becoming an important element of the "quick reaction force", an important tool in the country's defense system,

Thus, the proposed universal wheeled mover can have both military and national economic importance.
