ABSTRACT:
A vehicle anti-skid mechanism is a wheel attachment and fits on the outside of a vehicle wheel. The mechanism includes a central portion having an inner pair of plates between an outer pair of plates and tread members pivoted to each pair of plates. Turning the inner pair of plates relative to the outer plates displaces active portions of the tread members outwardly to more or less ground engaging positions. The tread members define the periphery of the mechanism and are configured to interfit with one another in their withdrawn inoperative positions. Hydraulic piston assemblies are mounted around the hub of the mechanism and connected to the inner pair of plates.
