Abstract

FIELD: vehicles.

SUBSTANCE: invention relates to a track propulsion apparatus. The track propulsion apparatus includes one or two wide belts configured to be located under the flat bottom of the vehicle, as well as toothed gears. The belts envelop the cylindrical rollers attached to the bottom of the vehicle. The end cylindrical roller has a toothed gear at the end, connected by means of a belt, chain or universal transmission with the gear located on the torque-transmitting axis. The toothed gears transmit rotation to the belts provided with holes along the entire length thereof for penetration of the teeth of the toothed gears.

EFFECT: passability is increased.

Description

SUBSTANCE: invention relates to methods for increasing the fifth wheel cross-country ability of tracked and wheeled vehicles with a flat bottom.

The closest analogue of the claimed invention, which coincides in purpose and in terms of general essential design features, is a method for increasing the fifth wheel cross-country ability of a tracked vehicle (RU 2690303 C2, B62D 55/26, B62D 55/27 published on 05/31/2019), which describes a tracked a machine equipped with road-roller extenders with additional lugs that automatically extend when driving.

The design of the known device does not ensure the movement of the vehicle when the friction force of the bottom against the ground prevails over the friction force of the moving tracks.

In difficult road conditions, or in conditions of a complete lack of roads, even tracked vehicles or all-wheel drive ATVs can get stuck. One of the reasons for this problem may be the situation when the vehicle sits down on the bottom of the ground. This occurs due to the looseness of the soil, or in the presence of a high track. The vehicle can continue to move as long as the friction force of the wheels (or tracks) exceeds the friction force of the bottom against the ground. But when the frictional force of the bottom becomes equal to the frictional force of the wheels (or tracks), the vehicle stops.

The object of the invention is to provide a device that allows the vehicle to continue driving under condition of loss of the necessary adhesion of the driving wheels or tracks to the surface caused by friction of the bottom against the ground in difficult road conditions.

This task is achieved by the fact that two belts are installed under the bottom of the vehicle, one of which is located along the left side of the bottom, the other along the right (or one belt for small vehicles). These belts are positioned on top of cylindrical rollers, which are positioned so that a small distance remains between the belt and the bottom. The end roller has a toothed gear at the end, which is connected by means of a belt, chain or cardan transmission to a gear located on an axle that transmits torque. Also on the extreme roller there are gears that fall into the holes in the belt. When the axle that transmits the torque is rotated, all connected mechanisms ensure the rotation of the belts. The left axis rotates the tape on the left, the right one on the right.

The essence of the invention is illustrated by drawings, where:

FIG. 1 is a general view of the mechanism;

FIG. 2 - the location of the rollers;

FIG. 3 is a general view of the mechanism without a tape;

FIG. 4 is a general view of the entire mechanism located on the vehicle (rear view);

FIG. 5 is a general view of the entire mechanism located on the vehicle (side view);

There are quite a few options for transferring rotation to the tapes from the drive axle of the vehicle. The transmission of rotation can be carried out by means of a belt, chain, worm and other types of transmission of rotational motion. For docking-undocking of mechanisms, hydraulic, electrical, manual and other auxiliary devices can be used. In the description below, one of the possible options for activating the mechanism will be considered (in general terms, since the device itself for connecting the tape to the drive axle is not the subject of patenting of this invention).

The all-terrain belt consists of two belts - 1 (or one for small vehicles), made of dense flexible material (cord-reinforced rubber). The belts go around rollers - 3 along the entire perimeter. Cylindrical rollers are inserted between metal brackets - 4, which in turn are attached to the bottom - 12 of the vehicle, using bolts or welding. On the cylindrical extreme rollers - 2 there are gears - 11, the teeth of which are inserted into the holes - 7, located on both sides of the belts along their entire length. On the outer edges of the cylindrical rollers - 2 there are toothed washers - 6. On the inner edges of the rollers - 2 there is a return mechanism, consisting of a toothed end - 20, a spring - 18, a ring - 17, rigidly connected to the mount - 21 and rings - 19, rigidly connected to the roller - 2. In this case, the roller - 2 can move freely in the fastening eye - 21 and the washers - 17. The drive mechanism consists of a toothed gear - 14, which is attached to the driving axle - 15 of the vehicle, a toothed belt - 8, a toothed gear - 13 and a toothed washer - 5, rigidly connected to the gear - 13. Between the axles - 2, fixed with fasteners - 21, there is a pusher - 16 (hydraulic or electric). To rotate all-terrain belts, it is necessary to turn on the pusher - 16, on the sides of which there are cylinders with a gear drive. The cylinders dock to the roller - 2, which has a gear train at the end and will press until the gear train - 6 to the gear train - 5. When all the gear drives are connected, the gear gear - 13 will transfer rotation to the roller - 2 from the belt - 8, which is connected with gear - 14, attached to the drive axle - 15 of the vehicle. The rotating roller - 2 will transfer the force to the gears - 11, which, falling with their teeth into the holes - 7, will rotate the tape - 1. The rollers - 3, inserted between the mountings - 4, will not allow the tape to touch the bottom of the vehicle. When the pusher - 16 is turned off, the spring - 18 will start pressing on the washer - 19, rigidly fixed to the roller - 2, and will return the roller - 2 to its inoperative position.

Claims (1)

A caterpillar propeller, characterized in that it includes one or two wide belts made with the possibility of being located under the flat bottom of the vehicle, which bend around the cylindrical rollers attached to the bottom of the vehicle, while the extreme cylindrical roller has a toothed gear at the end, which, by means of belt, chain or cardan transmission is connected to a gear located on an axle transmitting torque, as well as toothed gears transmitting rotation to belts having holes along their entire length for penetration of the teeth of the toothed gears.
