FIELD OF THE INVENTION The invention relates to vehicle engineering and relates to vehicles equipped with self-draining devices.

The purpose of the invention is to automatically change the speed of rotation of the winch drum for various modes of vehicle self-pulling when using the propeller of the vehicle itself being pulled out while reducing pulling time.

Figure 1 shows the device, a general view; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 2.

A motor 2 is fixed to the housing 1, the shaft 3 of which is connected via a coupling 4 to a gear unit consisting of a cylindrical gear 5 and a bevel gear 6 rigidly connected to each other and mounted in the housing on bearings 7 and B.

The cylindrical gear 5 engages with a gear wheel 9) on the axis of which the worm is rigidly fixed to 10, which engages with the worm wheel 11. The gear wheel 9 with the worm IO is mounted in the housing 1 on bearings 12 and 13. The worm wheel 11 is installed in the housing 1 on the sub / ips 14 and 15. On the hub of the worm gear 11, there are made profile grooves for mounting the rollers 16. On the axis of the worm gear

a worm to 10 which is engaged with a worm wheel 11. A gear wheel 9 with a worm 10 is mounted in housing 1 on bearings I2 and 3. A worm gear 11 is installed in housing 1 on bearings and is made with shaped grooves intended for mounting commercials. The outer cage of the one-way clutch is mounted on the axis of the worm gear; its hub serves as a shaft on which the drum is fixed, which is secured against turning by means of a freewheel key. 3 il.

the wheels are fitted with an outer race 17 of a one-way clutch, the sleeve of which serves as a shaft. A winch drum 18 is secured on this shaft and secured against rotation of the freewheel with key 19.

The bevel gear 6 engages with the gear wheel 20, in the sleeve of which there are blind holes for mounting the friction elements 21 with springs 22. Thus, the gear 6 forms the driving half of the clutch, the driven half of which is formed by the outer race 17 of the one-way clutch. On the drum 18 with one end secured the flexible body 23.

For The self-pulling device pulls up the vehicle, for example, it is attached to the front bumper of the car, and the electric motor is connected to the vehicle network. The free end of the cable is attached to a stationary object, for example, a tree trunk, a gear that drives the vehicle propulsion is activated: vehicles, for example, drive wheels are self-powered, and the motor of the self-pulling device is switched by a toggle switch.

In the case of wheel slip, the torque of the motor 2 of the device through clutch 4, gear 5,

a gear wheel 9, a worm to 10, a worm wheel 11, an outer race 17 of a freewheel, wedged with rollers 16 as a result of corresponding slotting, is transmitted to a winch drum 18 rigidly connected by means of a key 19 with the race 17.

Claims (1)

The flexible body, winding on the winch drum, reduces its length, and since one end is fixed on the winch drum and the other on a stationary object, the vehicle moves on an impassable stretch of road. Device for vehicle self-pulling, containing a motor with a shaft and a winch with a drum placed on a vehicle, on which a flexible I is wound and fixed by one buck 998674 a traction device, the other end of which is adapted to be connected with a fixed object, characterized in that, in order to automatically change the speed of rotation of the winch drum for various modes of vehicle self-pulling when using the movement of the vehicle itself being pulled out with simultaneous by reducing the pulling time, the winch is made with two rigidly connected gears with the engine shaft, one of which is connected with a gear wheel and a torque coupling ematicheski associated winch drum shaft, and the other through the second gear and rigidly fixed to its axis Single screw, the worm wheel 20 and the overrunning clutch is also bonded to said Ba. scrap drum winch. f1 / g. 23 Editor M.
