Description

one

This invention relates to a vehicle, namely towing devices.

A device for towing emergency and faulty cars is known, comprising levers with trays supporting the wheels of the towed car and a lifting mechanism with flexible thrust and grip at the end, pressing the axle of the car to the trays of the levers and ejecting the car after the wheels are fixed 1

However, using the device it is impossible to tow cars - in case of damage to the suspension with improper installation of the wheels of the towed car.

Closest to the proposed technical entity is a device for towing a car, which has a telescopic beam attached to the frame, with a lodgement turning in the horizontal plane, having a catch, equipped with a lock, and a lifting mechanism 2 located on the weight.

The drawback of the device is the lack of use for fixing various types of cars when towing, the need for precise orientation relative to the suspension of the towed car and its preliminary lifting by a crane.

The purpose of the invention is to increase the performance and versatility of the device by providing towing of various types of vehicles without prior detection.

The goal is achieved by the fact that the lodgement is provided with horizontal guides, and the grip is made in the form of two L-shaped racks, one of which is rigidly fixed on the lodgment, and the other is movable in the specified guides. mechanism.

20 details of capture before fixing the car; in fig. 5 - the same, at the end of fastening the suspension element of the car; in fig. 6 is a section A-A in FIG. 3; in fig. 7 is a section BB in FIG. 6. The vehicle for towing consists of a bracket 1, to which a telescopic stand 2 is welded. In the case 3 of the telescopic stand a movable element 4 is moved, at the lower end of which a sleeve 5 is fixedly mounted. In the sleeve 5 there is an axle hollow 6 sleeves 5. In axis 6, a cradle 8 and a block 9 are mounted on a horizontally located finger 7. In a horizontal position, the cradle 8 is fixed by stops 10 located on either side of the finger 7. On the cradle 8 there is a gripper 11 for mounting suspension and fastening elements of various types of vehicles, containing two L-shaped racks 12 and 13, one of which — rack 12 — is stationary, and the other 13 is provided with a supporting surface and is mounted so that it can be moved along the guide rails of the grip towards the stationary rack 12. On The bracket 14 of the movable stand 13 is fixed to the envelope blocks 15 and 9 of the bend 16 of the load-lifting mechanism 17 (for example, a mechanical winch), mounted under the frame 18 of the vehicle, with a tow gauge 19. The spring 20 is intended to return the movable stand 13 to the starting position. The gripper 11 is provided with a latch 21 of the position of the movable rack 13, consisting of the housing 22, from which the spring 23 extends under the action of the spring. The latch 24 is controlled by the clamp 24, which acts on the clamp 21 through the double-arm lever 25. On the rack 2 there is a brace 26, which, in the vertical transport position, is fixed by the pin 27 with the cradle 8. The device operates as follows. For towing an emergency or malfunctioning vehicle, the cradle 8 is installed in a horizontal position and lowers below the level of the suspension of the towed vehicle. By reversing the vehicle, the gacha 19 establishes the grip 11 under the suspension of the towed car, the load-lifting mechanism 17 is activated, the bending of which 16 pulls the MOVING element 4 of the telescopic pillar 2 with the lodgement 8 up to the stop of the grip 11 at the suspension element of the towed car, as at this moment, the mobile strut 13 is secured against movement by latch 23 of the retainer. Then, the 24 of the pin 23 of the retainer 21 is withdrawn from the opening of the base of the movable stand 13 and the rotation 17 continues. In this case the movable stand 13, moving in the direction of the fixed stand 12, closes the suspension element of the towed car. The pin 23 of the latch 21 is in the corresponding hole of the support surface of the rack 13 under the action of the spring of the latch. Upon further rotation of the load-lifting mechanism 17, the raising of the cradle 8 begins with the grip of the 11 fixed on it up to the level required for towing. The invention includes a device for towing a car, containing a telescopic beam attached to the frame of a tractor with a lodging pivot in a horizontal plane, having a catch, equipped with a lock, and a lifting mechanism placed on the tractor, characterized in towing various types of vehicles without prior warning, the cradle is provided with horizontal guides, and the grip is made in the form of two L-shaped toek, one of which is rigidly fixed to the cradle, and the other - to be movable in said guide and is associated with the flexible draft type lifting mehaniz.ma.
