ABSTRACT:
A four-wheel steering apparatus comprising a front wheel steering device having a front-wheel steering bar movable for steering front wheels, and a rear-wheel steering device having a rear-wheel steering bar mechanically separated from the front-wheel steering device and movable for steering rear wheels. The latter device has a rear-wheel steering bar drive assembly for moving the rear-wheel steering bar, and a rear-wheel steering control system for controlling the drive assembly in accordance with the steering amount of the front wheels to thereby control the amount of movement of the rear-wheel steering bar and control the steering amount of the rear wheels. The rear-wheel steering device comprises a maximum steering amount regulating assembly having a variably regulating member capable of mechanically restricting the maximum amount of movement of the rear-wheel steering bar and adjusting the maximum amount of movement. The maximum amount of movement of the rear-wheel steering bar to be mechanically restricted by the variably regulating member decreases as the vehicle speed increases.
