摘要

Anti-slip device for vehicle wheels equipped with treads, especially tires, for surfaces covered with ice or snow, consisting of a support disc that can be fixed to the wheel disc or rim with a number of anti-slip arms, which dicurren radially at equal distance from each other, with a previously curved profile bearing on its outer side at its free ends a gripping profile or tips for tires and which overlaps the running surface of the tire, such profile being a plastic material or other suitable material, characterized in that the device (100) consists of a support disc (120) fixed to the wheel disc (11), which carries a number of anti-slip spleens (140) with a previously curved profile, which overlaps the surface (14) of the tire, rotating around shafts (141) running parallel to the support axis of the wheel disk or rim (117), and because each of the axes anti-slip shoes (140) is provided with an accumulation of material (148) in the bent area (143b) to increase the weight in order to counteract the centrifugal force.
