Abstract

A wheel suspension system is provided for the driven steered and unsteered rear wheels of a motor vehicle comprising a wheel carrier which is supported on the vehicle body side by way of a spring strut. This wheel carrier is guided by two individual links forming and upper pivotal connection and by way of a lower pivotal connection consisting of an A-arm as well as a tie rod link extending approximately in the transverse direction of the vehicle. The individual links are arranged in a diverging manner in the vehicle transverse direction and are disposed in two spaced joints of the wheel carrier and, the A-arm is held on the wheel carrier by a joint so that both pivotal connections form an elastokinematic wheel swivelling axis and a kinematic swivelling axis. The two pivotal connections are so arranged and supported in joints such that a wheel suspension system is obtained which, on one hand, ensures a secure vehicle handling in all driving conditions with a good driving comfort and on the other hand, can be arranged in the vehicle in a spatially compact manner.
