Description

FIELD OF THE INVENTION The invention relates to vehicles and relates to devices intended for transporting damaged or faulty vehicles and trailers.

The purpose of the invention is to increase the operational capabilities.

The drawing shows towing

device, general view,

The towing device contains a central earring 1, connected by means of hinges 2 to 3, which consist of front 4 and rear 5 links connected by means of hinges 6 and have coupling loops 7 at the ends for connection with the object being towed. . In the middle inner part each has an additional 8 and external 9 damping 1 springs. Internal additional; Springs 8 are installed in telescopic cylinders 10.

The device works as follows

When towing an object, the load from the go-coupling device t to the gauge is transmitted to the central link 1, through the hinges 2 to the pulls 3 and to the towing loops 7, which under the action of force: the pulls tend to move forward. As a result of the applied force directed forward along the course of movement, and the force of resistance to movement acting on the object being towed and on

in the opposite direction on the towing device acts

A towing device containing hingedly connected ends of one link, equipped at the free ends with connecting elements, a spring installed at the conjugate ends of the links, so that, in order to increase operational capabilities , it is equipped with a two shoulders with a central earring, one shoulder of which (is pairwise connected to the free end of one of the links by means of a connecting element, and the spring with its ends is directly fixed

The breaking force that tends to expand the levers into a straight line and damage it. This is prevented by external ones. “On the conjugate links, by means of damping springs, working on brackets, to which is also an extension, which provide a coaxially arranged inside, the telescopic cylinder reliably increases traction load and prevents the towing device installed inside it and the hitch from damage - with an additional spring, at the same time to the scientific research institute, as a result of which the tramming of the trailer takes place without a jerk, and therefore - and without slipping with the towing vehicle, which is especially important on soft ground.

Another shoulder of the central earring is also pivotally attached to a device symmetrically located similar to that attached to the first shoulder.

Q

In the event that the drag forces acting on the object being towed become greater than the elastic force of the external damping springs, the towing device is pulled to its maximum rearward position and the towing is carried out as on a rigid hitch (double rigid tow).

During braking, a force of inertia of the towed object arises, which tends to fold down the towing device, and to break it under heavy braking. In this case, internal damping springs 9, working in compression, which eliminate the impact or significantly diminish its force, come into operation. When rolling, the towing device takes the extreme forward position. After the braking is stopped, the internal springs 9 occupy the initial position.
