Description

The invention relates to mechanical engineering and can be used to increase the cross-country ability of road vehicles, including heavy trucks, with periodic equipment during operation to overcome road sections on which the wheels slip and the car stops for this reason.

Known devices designed to eliminate slipping [Gornushkin Yu.G. Practical advice to the car owner. - M .: Patriot, 1991, 207 s, ill.], For example, traction chains, studding or traction cuffs [Gornushkin Yu.G. Practical advice to the car owner. - M .: Patriot, 1991, 207 s, ill., Fig. 64], rubber anti-skid chains [Gornushkin Yu.G. Practical advice to the car owner. - M .: Patriot, 1991, 207 s, ill., Fig. 66].

Spikes on the tire are ineffective on a road covered with dirt or snow. Traction chains have little contact with the road, therefore, are ineffective. Anti-skid rubber chains are ineffective at low temperatures on snowy roads or in clay-covered areas. To install them, you must use a jack, which is associated with a significant waste of time.

The closest in technical essence to the claimed invention is a device for increasing the cross-country ability of a car (RF patent 2394694, B60C 27/02, B60C 27/06, B60B 15/22, publ. 07/20/2010), which contains a chain, an arched bar with two holes into which the tie rods are inserted with a nut to which the chain is attached, while the arcuate bar is made with the possibility of fastening to the wheel rim with the help of a pin.

A significant disadvantage of the prototype is the low anti-slip ability due to the small area and depth of contact with the road.

The invention will solve the problem of increasing the patency of vehicles on any road with poor quality coating or without it in difficult natural conditions by increasing the area and depth of contact with the road.

This is achieved by the fact that in the device for increasing the cross-country ability of the vehicle, including an arcuate strip with the possibility of fastening to the wheel rim with the help of a hairpin and the traction control device according to the invention, the traction control device is made of at least three with the possibility of quick connection-disconnection of the lugs, wherein each lug is made in the form of a plate with gear teeth made in the plane of the lug on the outside, at least re, two flexible elements, the free ends of which are equipped with a mount.

Brief Description of the Drawings

In FIG. 1 is a front view of one embodiment of the present invention in operational condition;

in FIG. 2 shows a top view of FIG. 1;

in FIG. 3 shows one embodiment of the lug of FIG. 1;

in FIG. 4 shows one embodiment of the attachment assembly of FIG. 1.

In FIG. 1-4 are indicated:

1 - lugs made, for example, of metal;

2 - flexible elements made, for example, of rubber fabric tape;

3 - mounting assemblies;

4 - narrow rectangular holes made in the plane of the lugs 1;

5 - the edge of the lug 1, bent up;

6 - gear teeth made in the plane of the lug 1 from the outside;

7 - element of the mount, mounted on the flexible element 2;

8 - element bond fastening mounted on an arcuate strip 9.

A device for increasing the patency of a vehicle, as shown in FIG. 1 and FIG. 2, consists of interconnected lugs 1, flexible elements 2, attachment points 3. Each lug 1, in accordance with FIG. 3, is a metal plate in the shape of a trapezoid with holes of different shapes. Narrow rectangular holes 4 are made parallel to the larger base and have a length equal to the smaller base of the trapezoid. The smaller edge 5 of one lug 1, bent upwards, which is simultaneously a gear tooth, is bent up and enters one of the narrow rectangular holes 4 of the adjacent lug and provides reliable adhesion to each other. The teeth of the engagement 6 are made, for example, by cutting oval half-openings on the plane of the lug 1 and bending up the edges. Flexible elements 2, for example, are made of rubber-fabric tape and are rigidly fixed to the lug on opposite sides by a bolt connection. The fastening of the flexible elements 2 to the lugs 1 can be carried out with several bolts of different lengths at different distances. The free ends of the flexible elements 2 are fixed by the attachment points 3 on the arcuate bar 9. The attachment node 3 consists of two elements, one of which, for example, is made in the form of a hook 7 [http://spb-k.ru/catalog/stena/Krepej , circulation date 05/18/16; http://evv.su/dlja-gruzovykh-avtomobilei/stjajka-kreplenija-gruza/, accessed 05/18/16], as shown in FIG. 4, is located on the free end of the flexible element 2, and the other, made, for example, in the form of a hole 8, is on the arcuate strip 9.

The number of lugs 1 depends on the size of the wheels of vehicles. The proposed minimum amount of three is due to the standards of automobile wheels: the traction control device must cover at least 1/5 of the entire working surface of the tire. The average width of the lugs 1 is equal to the minimum width of the produced tires. The presence of flexible elements 2 allows the device to be used on wider tires, in these cases, the bolt fastening of the flexible element 2 to the lug 1 additionally plays the role of a gear tooth.

In the case of lugs 1 in the form of discs, we obtain an oval shape of the teeth of the gearing. This changes the contact with the road, which begins pointwise, and ends along the entire length of the tooth.

To install the device on the vehicle’s tire, it is necessary to connect the required number of lugs 1 to each other and fix it to the arcuate strip 9 with flexible elements 2 inside, install the arcuate strip 7 on the wheel, then fix the flexible elements 2 from the outside. The number of constituent elements of the device to increase the cross-country ability of the car can also be determined by the quality and condition of the road surface.

A device for increasing the patency of the car as follows.

After installing the device on wheels and continuing driving on an impassable section of the road, the wheels of the car part of the surface are in contact with the road, and part with the inner surface of the device. When the device hits the road surface, the teeth of the gears 5 and 6 of the lugs 1 cut into the ground at different depths and different profiles, thereby providing the possibility of further advancement.

When driving on a road with a high-quality coating, the device for increasing the cross-country ability of the vehicle must be removed.
