ABSTRACT:
TECHNICAL FIELD
The present invention relates to a self-locking drag link for a steer-by-wire system in a motor vehicle, and to a steer-by-wire system incorporating such a self-locking drag link.
BACKGROUND OF THE INVENTION
There is a proposal to provide a steer-by-wire system in a motor vehicle in which the system comprises an electrical actuator associated with the steering knuckle at each front wheel of the vehicle.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a mechanical link between the two electrical actuators so that, should one of the actuators fail, the remaining actuator will provide steering for both wheels.
In the present invention, a failure of one of the electrical actuators will result in the piston member moving (relative to the housing member) beyond the normal range of movement (when both actuators are functioning correctly). The excessive movement of the piston member actuates the lock means to cause the piston member and the housing member to become locked together.
