ABSTRACT:
Antiskid device for the advance on snow or ice of the driving wheels of motor vehicles. The device is wheel-shaped and has a central hub portion intended to be applied and fixed to the outside of a driving wheel of a motor vehicle, a peripheral deformable crown with a spiked or jagged contour for gripping the roadbed and a plurality of spring-loaded and fluid-operated telescopic spokes to allow the crown to yieldingly deflect, so as to lose its normal circular shape at the portion of the crown gripping the roadbed and to resume and keep its normal circular shape in all its remaining portions.
The amount of the extension/retraction of the spokes can be controlled remotely from inside the vehicle to which the device is applied.
