ANTI-SKID DEVICE FOR WHEELED VEHICLES

摘要

An anti-skid device for wheeled vehicles comprises a hub-like support secured coaxially to a wheel and carrying equally spaced about its periphery a plurality of pivotally mounted arm and gripping member assemblies. Springs urge the assemblies either into a retracted rest position or a use position in which free ends of the gripping members lie over the road engaging surface of a pneumatic tyre on the wheel and spikes on said free ends provide a grip between the tyre and an icy road surface, the gripping members being able to pivot when the tyre flexes.
