摘要:
A steer-by-wire steering system includes a steering motor, a steering power transmitting mechanism for transmitting a rotation of the steering motor to a steering axle, a toe angle adjusting motor and a toe angle adjusting power transmitting mechanism for adjusting the toe angle upon rotation of the toe angle adjusting motor. A switching mechanism is provided which operates in such a manner that in the event of failure of the steering motor, the rotation of the toe angle adjusting motor in place of the steering motor is transmitted to the steering power transmitting mechanism to enable a wheel turning, but in the event of failure of the toe angle adjusting motor, the wheel turning is carried out only by the steering motor. A hollow motor is employed for one or both of the steering motor and the toe angle adjusting motor.
