    • A front and rear wheel steering system for a vehicle has a front steer system (23, 25) and a rear steer system (21, 22) with a rear steer controller (12) functioning to set the rear steer angle in dependence upon front steer angle and vehicle speed. A low load capacity feedback device (14) functions to maintain a predetermined relationship between front and rear wheel steer angles with an overload protector (74, 77, 78) protecting the feedback device (14) from damage due to the application of loads above a predetermined level.

    • A rear wheel steering device for a vehicle which is provided with a rear wheel steering shaft which steers rear wheels by its displacement, a neutrally holding means which constantly biases the rear wheel steering shaft to the neutral position, a motor which is linked with the rear wheel steering shaft and changes the steering angle ratio which is a ratio of the rear wheel steering angle to the front wheel steering angle by displacing the rear wheel steering shaft and an oil pressure assist means which assists displacement of the rear wheel steering shaft by the motor by oil pressure force. This device is further provided with oil pressure supply means which supplies oil pressure to the oil pressure assist means and oil pressure control means which, when working the motor at the initial check, controls the oil pressure supply means to make the oil pressure assist means supply oil pressure to the oil pressure assist means before working of the motor.
    • 一种用于车辆的后轮转向装置,其具有通过其位移来转向后轮的后轮转向轴,将后轮转向轴恒定地偏压到中立位置的中立保持装置,与后方连接的电动机 车轮转向轴,并且通过使后轮转向轴移位来改变作为后轮转向角与前轮转向角的比的转向角比,以及通过电动机辅助后轮转向轴的位移的油压辅助装置 通过油压力。 该装置还具备向油压辅助装置和油压控制机构供给油压的油压供给机构,在初次检查时对电动机进行加工的情况下,控制油压供给机构使供油辅助装置 在电动机工作之前对油压辅助装置的油压。
