IPC: B62D7/14
Filed: 1989-09-05
Abstract: PURPOSE:To eliminate a poor condition generated near the maximum steering angle by composing the system to limit the steering angle control value of the front wheels at the time when the actual auxiliary steering angle of the rear wheels reaches to the preset maximum steering angle. CONSTITUTION:The steering input to a steering handle 3 is delivered to the front wheels 1 through a steering gear 4.

And at the rear wheels 2, the auxiliary steering is available to the maximum angle B deg. by the stroke of an actuator 6. And when the actual auxiliary steering angle of the rear wheels 2 reaches to the maximum steering angle, the steering angle control value is limited by the own value of the front wheel steering angle at that time responding to it. As a result, the actual auxiliary steering angle of the front wheels 1 is not increased more than the limit value, and the problem of the deterioration of steering feeling and the reduction of the operating safety generated near the maximum steering angle can be solved.
