Abstract
An antiskid device is provided for a vehicle wheel comprising a detachable antiskid rolling track on the periphery of the wheel, a central housing for holding radial linking elements or arms which are also attached to chain guides inserted in said rolling track, and a return member designed to automatically position the rolling track and hold it on the periphery of the wheel. The rolling track comprises resilient elements capable of eliminating the play between the peripheral surface of the tire and said antiskid rolling track.
Claims36
An antiskid device for a vehicle wheel comprising:
- a movable antiskid rolling track on the periphery of the wheel;
- a central housing having a plurality of radial connecting arms extending therefrom;
- chain guides attached at a distal end of said radial connecting arms;
- said chain guides being inserted in said rolling track;
- a return means for automatically positioning said rolling track on the wheel and holding the rolling track on the periphery of the wheel;
- said rolling track comprising a plurality of resilient means, each of which is resilient in the longitudinal length of the rolling track, for pressing said rolling track against the peripheral surface of the wheel, thereby eliminating the play between the peripheral surface of the wheel and said antiskid rolling track.
