ABSTRACT:
A traction device for wheeled vehicles comprises a frame for securing to a wheel of a vehicle; a grip enclosure operably secured to the frame; a grip assembly radially slidably received within the grip enclosure; and an actuator secured to the frame for extending and retracting the grip assembly in the radial direction of the wheel. The grip assembly includes a flexible outer end portion adapted to automatically follow substantially the peripheral cross-sectional shape of the tire when in the extended position. The grip enclosure includes a guide portion adapted to receive and straighten the flexible outer end portion when the grip assembly is in the retracted position. A sprocket chain is operably secured to the flexible outer end of the grip assembly. It provides rigidity to the flexible outer end in the plane of rotation of the tire and flexibility in the transverse direction into the plane of the tire.
