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.
