The invention relates to the field of automotive industry, in particular to the additional equipment vehicles, primarily to means for improving the patency of the car.

From the information publicly available before the priority date of the claimed technical solution, the following means the same destination.

A device for increasing the permeability of a motor vehicle comprising a removable lugs, coupled with the lever, is arranged to be attached to the hub of the car through the anchor bolt passing through the body of the wheel, while boarding and threaded elements mentioned bolt similar to the corresponding elements of standard wheel bolts (see, for example, patent RF №2037431, MKI VW 15/18, 1993).

A disadvantage of the known device is that it is not possible to obtain a technical result - improving performance and reducing shock loads on the parts of the transmission.

Shortcomings in the patented device is achieved by the fact that the claimed device is mounted on the wheel of the car in all conditions by removing only one of the wheel bolt. It does not require jacking the stuck car. In addition, the design of the lug and pivotally fixed to the wheel hub provide a reduction in the ary loads on parts of the transmission at the start of rotation of the drive wheel and when you change the direction of its rotation.

It is also known a device for increasing the permeability of a motor vehicle comprising a removable lugs, coupled with the lever, is arranged to be attached to the hub of the car through the anchor bolt passing through the body of the wheel, while boarding and threaded elements mentioned bolt similar to the corresponding elements of standard wheel bolts (see, for example, patent RF №2238855, MKI VW 15/22, 2002).

This unit is closest to the claimed and therefore adopted for the prototype.

The disadvantage of the prototype is that its mounting on the wheel is hampered by the need to raise the car body and inconvenient, because the installation of the lug is in the mud in the wheel recess. The disadvantage of the prototype is the appearance of shock loads on parts of the transmission because of its large support surface anchoring and availability of metal ribs.

In contrast to the known technical solutions claimed the device is mounted on the wheel of the car in all conditions by removing only one wheel bolt that does not require jacking the stuck car. In the inventive device the design of the lug and pivotally fixed to the wheel hub reduce shock loads on parts of the transmission at the beginning of the rotation the drive wheel and when you change the direction of its rotation.

The invention aims to obtain a technical result - improving performance and reducing shock loads on the parts of the transmission.

Below is General and private significant features that characterize the causality of the invention with the specified technical result.
