ABSTRACT:
A rear steering system in which a rotary mechanical input obtained from one of the rear wheels is controllably applied to a rear steering rack through an electromagnetic clutch apparatus operated by an electronic control unit. The rotary mechancial input is achieved with a flexible cable gear driven by the rear wheel. The cable provides a rotary mechanical input to a magnetic particle clutch assembly, which in turn, interfaces with the rear steering rack via a bevel gearset. The clutch assembly is controlled by an electronic control unit which responds to a variety of system parameters such as the front and rear rack positions, forward/reverse indication and the speed of the vehicle.
