ABSTRACT:
Rear wheels are returned to central orientations when a rear wheel steering mechanism of 4WS system fails to operate. Required drive power is minimized and the apparatus is reduced in size. A main motor M1 is coupled to a steering shaft 1 through a drive transmitting mechanism 1a, 5a, 5b and 6a, and an auxiliary electric motor M2 is coupled to a drive shaft 6 through a gear mechanism 9, 12, 8a, 7 which includes a solenoid operated clutch CL. The motor M2 is normally disengaged from the drive shaft, but upon detecting the occurrence of a failure, the clutch is activated and the motor M2 is set in operation for returning the steered position of the rear wheels to the center.
