Abstract: A vehicle steering system includes a steering input device, a front steering subsystem, a rear steering subsystem, a first force transmission route, a steering control mechanism, a second force transmission route, and a third force transmission route. The front steering subsystem is coupled to front motive members to steer the front motive members based upon movement of a front steering subsystem input shaft. The rear steering subsystem is coupled to rear motive members to steer the rear motive members based upon movement of a rear steering subsystem input shaft. The first force transmission route extends from the steering input device to the front steering subsystem input shaft, wherein force is transmitted from the input device to the front steering subsystem input shaft to steer the front motive members. The steering control mechanism has a movable input member and a movable output member. The movable input member is movable through a first distance without transmitting force to the output member and is movable through a second distance in which force is transmitted to the output member to move the output member. The second force transmission route extends from the steering input device to the input member, wherein force is transmitted from the input device to the input member to move the input member. The third force transmission route extends from the output member to the rear steering subsystem input shaft to move the rear steering subsystem input shaft and to steer the rear motive members.

Abstract: In a rear suspension system for a four-wheel-steered vehicle, each wheel support is connected to a rear wheel turning rod so that the rear wheel on the wheel support is turned about a king pin axis when the rear wheel turning rod is displaced. Upper and lower arms define the king pin axis, and the rear wheel on the wheel support is turned about the king pin axis in response to displacement of the rear wheel turning rod. The king pin axis is tilted inward from the vertical and intersects the tread of the rear wheel at a point which is longitudinally offset from the point at which a side force acts on the rear wheel during cornering. A coil spring is connected between the wheel support and the vehicle body and restrains vertical motion of the wheel support under the counterforce thereof. The line of action of the counterforce is tilted with respect to the king pin axis so that it is not parallel to the king pin axis, does not intersect the king pin axis and is directed such that the counterforce generates a moment which tends to turn the rear wheel in the direction opposite to the direction in which the moment generated by the side force acting on the outer of the rear wheels tends to turn the outer rear wheel when the vehicle corners.

Abstract: In a four wheel steering system, the rear wheel turning mechanism is connected to the front wheel turning mechanism by way of a rear wheel turning angle ratio changing mechanism which is mechanically connected to both the front wheel turning mechanism and the rear wheel turning mechanism and transmits the mechanical displacement input thereinto from the front wheel turning mechanism to the rear wheel turning mechanism to drive the same by an amount the ratio of which to the amount of mechanical displacement input into the rear wheel turning angle ratio changing mechanism gives a predetermined rear wheel turning angle ratio. The rear wheel turning angle ratio changing mechanism is controlled in such a way that, when the front wheels are turned from the neutral position in a middle vehicle speed range, makes the rear wheel turning angle ratio negative for a moment immediately after initiation of turning of the front wheels and thereafter turns the same positive.
