The anti slip device for automobile wheels with wheel discs arranged at inner side plain of the wheel, load-bearing part of which is attachable to the wheel from the outside. The extensible body is placed slidingly in the direction parallel to the wheel axis on the load-bearing part. There are arms fulcrumed on the extensible body around axes parallel to the wheel axis. The arms are fitted, at their ends, with surfaces of engagement, which bear against the tire peripheral surface in the working position. The extensible body is placed on the load-bearing part in the guidance, which comprises at least two pipes, with one outer pipe placed slidingly on each of the pipes and attached to the extensible body. There are tensile springs arranged in the pipes, and these springs are attached by one end to the load bearing part, and by the other end to the extensible body.

An anti slip device for an automobile wheel arranged about an axis, the wheel including a wheel disc (3) arranged at an inner side plane of the wheel and a tire (1) surrounding the wheel disc, the anti slip device comprising: a loading-bearing part (4) attachable to the wheel disc (3) from an exterior thereof;an extensible body (8) slidingly connected to the load-bearing part in a direction parallel to the axis of the wheel;a plurality of arms 9 extending directly from said extensible body, each of said arms extending radially outwardly from the axis of the wheel and terminating, at an end thereof distant from said extensible body, in a surface of engagement (10) lying parallel to the axis of the wheel, wherein, in a working position of said anti slip device, said surfaces of engagement of said plurality of arms engage a peripheral road-engaging, surface of the tire (1); and further including a driving assembly, said driving assembly adapted to shift a position of the extensible body (8) and to rotate arms (9);wherein said driving assembly comprises a pneumatic driving assembly, including a source (13) of compressed air, bellows (15) for shifting of the extensible body (8), pneumatic motors (16) for turning of arms (9), and control components (14). 4. The anti slip device of claim 3, wherein said control components (14) are fitted with remotely electrically controlled regulation elements. 5. The anti slip device of claim 1, wherein: said extensible body (8) includes a plurality of bearers (11), each of said plurality of bearers including a radially extending bore; andone of said plurality of arms (9) is slidingly disposed in a radially extending bore of one of the bearers (11). 6. An anti slip device for an automobile wheel arranged about an axis, the wheel including a wheel disc (3) arranged at an inner side plane of the wheel and a tire (1) surrounding the wheel disc, the anti slip device comprising: a loading-bearing part (4) attachable to the wheel disc (3) from an exterior thereof;an extensible body (8) slidingly connected to the load-bearing part in a direction parallel to the axis of the wheel;a plurality of arms 9 extending directly from said extensible body, each of said arms extending radially outwardly from the axis of the wheel and terminating, at an end thereof distant from said extensible body, in a surface of engagement (10) lying parallel to the axis of the wheel, wherein, in a working position of said anti slip device, said surfaces of engagement of said plurality of arms engage a peripheral, road-engaging, surface of the tire (1), wherein each of said arms includes a flat portion extending radially outwardly from the axis of the wheel, and wherein, in said working position of said anti slip device, an inner surface of said flat portion engages a side surface of the tire. 7. The anti slip device of claim 1, wherein in a second position of said anti slip device, said arms are drawn radially inward toward said extensible body, such that said surfaces of engagement of said plurality of arms are disposed radially inwardly from said peripheral, road-engaging, surface of said tire. 8. The anti slip device of claim 7, wherein in said second position said extensible body, said arms, and said surfaces of engagement are disposed axially exteriorly to said tire.
