Description

The claimed utility model relates to the field of a method for the evacuation of motor vehicles and a device for its implementation

The utility model relates to the field of vehicle evacuation. A way to evacuate a car by moving it to the place of repair using a special rolling cart with a pneumatic jack, driven by the car's pneumatic system.

To evacuate a damaged or faulty vehicle, a trolley with a pneumatic jack is placed under the front beam of the towed vehicle, the pneumatic jack is connected to the pneumatic system of the towing vehicle, and the front axle of the evacuated vehicle is lifted above the ground. If necessary, the towed vehicle is fastened with belts to the suspension or frame elements to the lugs. With the help of the drawbar, the pneumatic jack trolley is hooked up to the towing vehicle and then evacuation is carried out.

According to the technical essence and the achieved result, there is a car trailer for towing by the method of partial loading under the patent for a useful model of the Russian Federation No. 114656, class B62D 53/04, containing a drawbar, a basic support structure made in the form of a rectangular beam, to the ends of which brackets are attached, with placed in them wheel hubs, while on the beam there is a loading platform mounted with the ability to rotate on an axis located in the center of the beam and resting on the sliding plates, and on the lower side of the loading platform there are mechanical limiters of rotation, limiting the maximum angle of rotation of the platform.

The disadvantage of such a trailer for towing by the partial loading method is that in order to ensure the required angle of rotation of the loading platform relative to the supporting beam and the drawbar when towing a car on bends, a significant increase in the distance of the trailer wheels in width from the towed vehicle is required, which significantly increases the overall width of the road train, reduces performance maneuverability and controllability. The disadvantages include the fact that the faulty car must also have a serviceable front axle in order to be able to roll onto the loading platform.

In the utility model to the patent RU 174781 U1, a trolley for towing a car by the partial loading method is presented, in which the support-running apparatus is made of one-wheel, while the running wheel is located in the inner space of the turntable and the loading turntable, and the axis of the running wheel is horizontally fixed on brackets installed on the frame is located in a vertical transverse plane passing through the axis of rotation of the turntable, and the upper part of the running wheel protrudes above the surface of the loading turntable by an amount less than the ground clearance of the towed vehicle.

The disadvantage of this utility model is that it is intended for the evacuation of passenger cars and is unstable. In addition, if the front suspension of a car is faulty and it cannot move, then it is rather difficult to roll such a car onto a rolling cart.

The utility model (Patent RU l75339 U1) presents a trailer, which contains a drawbar pivotally coupled with two telescopic transverse rods located in a horizontal plane parallel to one another, two pivotal levers are pivotally attached to the edges of the rods, to which the wheel hubs and trailer wings are attached ... Two tie rods with two levers at the edges form the “frame” and loading platform of the trailer. When turning, the drawbar, driven by the vehicle by the tractor, shifts the lateral rods in opposite directions relative to each other, turning the levers with the wheels at an equal angle after the tractor. The disadvantage is that the wheels of the trailer extend beyond the dimensions of the vehicle. The evacuated vehicle must have a good front suspension and it is designed for towing cars.

The utility model (Patent RU 2066643 C1) presents a trailer for towing damaged vehicles. The trailer is designed for towing damaged vehicles, containing a frame mounted on wheels, a drawbar, a boom mounted on a frame with the ability to rotate in a vertical longitudinal plane, a traverse with gripping elements, hinged at the free end of the boom with the ability to rotate in a transverse vertical plane, characterized by the fact that it is equipped with a base mounted on a frame that is rotatable in a horizontal plane, on which said boom is mounted, while the gripping elements are hinged at the ends of the traverse with the possibility of pivoting around the longitudinal axis of the traverse, the front end of the frame is hingedly connected to the drawbar with the possibility of rotation in the vertical longitudinal a plane for hanging the front part of the damaged vehicle being towed and fixing in a horizontal position during transportation by a fixing mechanism.

As disadvantages, it should be noted the complexity in the manufacture and its transportation as a towing device to the tow truck.

The essence of the presented utility model consists in creating a compact rolling cart with a pneumatic jack for towing a faulty or damaged vehicle by the partial loading method, which is characterized by improved maneuverability and controllability when towing a vehicle by lifting the towed vehicle above the bogie wheels using a pneumatic jack.

The car is lifted by rolling the trolley itself with a pneumatic jack under the front axle or the transverse beam of the faulty car and then, due to the pneumatic jack, it is hung above the ground level. Air is supplied to the pneumatic jack from the air valve of the towing vehicle pneumatic system using an air hose.

After hanging the towed vehicle, the structure is additionally secured with safety belts.

In order to remove a rolling cart with a pneumatic jack from under the towed vehicle, the safety belts are untied, air is released from the pneumatic jack, the lifting platform is lowered, and the cart rolls out.

Placing the wheels of a rolling carriage with a pneumatic jack inside the track of the evacuated vehicle (Fig. 2) does not increase the dimensions of the road train, which does not affect the cross-country ability. The distance between the wheels of a rolling carriage with a pneumatic jack and the wheels of the towed vehicle allows maneuvering within the turning radius of vehicles.

The design of a rolling cart with a pneumatic jack makes it possible to evacuate vehicles not only with a damaged front axle, but also from the rear. In this case, the steering control of the car is fixed, the trolley is placed under the rear axle and the car is suspended using a pneumatic jack. Then the structure is fixed to the lugs (14) with safety belts (17), after which the damaged vehicle is evacuated.

In the transport position, the trolley with a pneumatic jack is disassembled into its component parts (Fig. 3) and is easily transported in the back of a truck. If it is necessary to use it for its intended purpose, it is also easily assembled and connected to the pneumatic system of the car using an air hose.

The device consists of a frame (5) with a drawbar (3) for attaching to the towing vehicle (1). In the center of the frame (5) there is an axis of rotation (11), on which the base (7) rotates. To reduce friction when turning, sliding plates (12) are located between the frame (5) and the base (7). The stops (6) limit the turning radius of the base (5). A pneumatic jack (8) is located between the base (7) and the lifting platform (9). The guides (13) allow the lifting platform (9) to move vertically. On the lifting platform (9) between the holders (10) there are rubber pads (15) on which the front beam of the towed vehicle (16) is placed.
