Abstract
PURPOSE:To aim at enhancing the running ability of a vehicle due to use of a four wheel steering vehicle by steering the rear wheel in a direction reverse to the steering direction of the front wheel during running at a low speed, and by steering the rear wheels in the same direction as that of the front wheel during running at a high speed. CONSTITUTION:During running at a low speed, since hydraulic pressure which is fed into a second oil supply passage 19b from a second hydraulic pump 29 driven by a front feel drive axle 3 is relatively low, and a change-over valve 28 is urged by an urging member 28a so as to be held at a first position. At this time, when a steering wheel is turned, the rear wheels are steered in a direction reverse to the steering direction of the front wheels since the change- over valve 28 is held at the first position. During running at a high speed, hydraulic oil having a pressure higher than that of the second hydraulic pump acts upon one end of the change-over valve 28 through the second oil supply passage, thereby the change-over valve 28 is turned into a second position. At this time, when the steering wheel is turned, the rear wheels are steered in the same direction as that of the front wheels since the valve is held at the second position.
