RU184129U1 - Universal towbar for towing vehicles - Google Patents

Abstract

The utility model relates to transport engineering, in particular to the coupling devices of vehicles and is intended for the evacuation of products with a faulty brake system, as well as not having standard towing hooks and eyes in their design.

Known universal hitch allows towing vehicles using standard tow hooks.

The main disadvantages of these towing devices are the impossibility of towing products in the absence of towing hooks or eyes of a certain shape for attaching a towing earring and the absence of a buffer for damping shock when towing over rough terrain.

The objective of this utility model is to increase the towing capabilities without crew vehicles, vehicles with a faulty brake system or lacking brackets for towing using standard means.

The technical result of the proposed utility model is:

1. The ability to tow various tracked and wheeled vehicles over rough terrain.

2. The ability to tow vehicles that do not have standard towing mounts.

3. The ability to tow vehicles with a faulty brake system.

The utility model can be used to evacuate military ground robotic vehicles, wheeled and tracked vehicles.

Description

The utility model relates to transport engineering, in particular to the coupling devices of vehicles, and is intended for towing products with a faulty brake system, as well as not having standard towing hooks and eyes in their design.

The utility model can be used to evacuate military ground robotic vehicles, wheeled and tracked vehicles.

Universal couplings are known that allow towing vehicles using standard tow hooks: copyright certificate No. 2263032, dated June 15, 2004 and No. 172954 of August 23, 2016. The main drawbacks of these towing devices (Hitch) are the impossibility of towing products in the absence of towing hooks or eyes of a certain shape for attaching the towing earring and the absence of a buffer to absorb shock when towing over rough terrain.

Ground robotic military equipment (RTS VN) such as Nerekhta, Uran-9, Companion, Kungas, and others do not have towing hooks, and the dimensions of the eyes do not allow the attachment of standard towing couplings and cables. In addition, in the case of towing a faulty RTS VN there is no possibility of manual control of the brakes, which leads to the impossibility of towing using tow cables.

A characteristic feature of the universal towing device (UTSU) is a towing means gearing based on a double-lever self-locking grip that allows towing without the use of standard towing devices in case of their absence or damage. The engagement is made by tightly pressing the levers equipped with rubber dampers to the side surface of the guides or driving wheels having recesses. Due to the tightening mechanism, the compression force, and hence the fixation of the towed product, increases in direct proportion to the towing force.

The sequence of operation of the device is as follows:

after determining the width of the towed vehicle, the UTSU levers are moved to the required distance;

buffers are mounted coaxially with guides or drive wheels depending on the direction of towing;

pre-tightening the levers of the UTSU, by rotating the nut of the locking device;

at low speed of the tractor, the final fixation of the levers is made and the towing device is locked;

towing is carried out.

The objective of this utility model is to increase the towing capabilities without crew vehicles, vehicles with a faulty brake system or lacking brackets for towing using standard means.

Technical solutions of the proposed utility model are:

1. The use of a self-tightening hitch that grabs the guides or drive wheels of the tracked chassis.

2. The use of rubber dampers at the ends of the levers as buffers for damping jerks when towing over rough terrain.

The technical result of the proposed utility model is:

1. The ability to tow various tracked and wheeled vehicles over rough terrain.

2. The ability to tow vehicles that do not have standard towing mounts.

3. The ability to tow vehicles with a faulty brake system.

A useful model is illustrated in FIG. 1, which shows a universal towing device for towing vehicles, where: 1 - a towing ring, 2 - a locking mechanism, 3 - a lever tightening mechanism, 4 - a rubber damper.

After the tractor approaches the caterpillar chassis awaiting evacuation, the UTSU levers are turned on, so that the rubber dampers coaxially pressed against the guide or drive wheels. Next, the hitch levers are pre-tightened by pulling the rod and rotating the lock nut. The UTSU is fastened by the towing ring to the towing device of the tractor, and with a small stroke of the tractor, the final reduction of the levers and locking of the tightening mechanism are performed. Towing can be carried out using a standard towbar mounted on vehicles, or using towing hooks of tracked vehicles using additional rods.
