Vehicle suspension system having toe direction control means.

摘要

A vehicle rear suspension system including a wheel hub (15) supporting a rear wheel (3) for rotation, a front lateral link (4) extending transversely and connected through a front inner rubber bush (8) with the vehicle body (8) and through a front outer rubber bush (12) with the wheel hub, a rear lateral link (5) extending transversely and connected through a rear inner rubber bush (10) with the vehicle body and through a rear outer rubber bush (14) with the wheel hub. The rubber bushes have resiliencies such that deflections are produced under a transversely inwardly directed side force applied to the wheel from a road on which the wheel is running to produce a change in a toe direction of the wheel in a manner that the toe direction is changed with respect to an increase in the side force with a first rate under a first range of the side force, with a second rate which is smaller in a sense of toe-in direction than the first rate under a second range of the side force which is larger than the first range and with a third rate which is larger in a sense of toe-in direction than the second rate under a third range of the side force which is larger than the second range.
