Abstract
A mechanical clutch coupling back-up system for use with a steer-by-wire arrangement in a vehicle is disclosed. The system includes an input shaft, an output shaft, a clutch assembly, and an actuator assembly. In the event of vehicle power failure, the actuator assembly permits the clutch assembly to provide a mechanical coupling of the input shaft and the output shaft thereby allowing the operator to drive the vehicle without the steer-by-wire system. The actuator assembly includes an actuator and the clutch assembly includes a movable clutch collar which is movable between a disengaged position when vehicle power is present and an engaged position when vehicle power is absent.
