Abstract

A suspension is provided for non-steered wheels on a motor vehicle body. The suspension includes, but is not limited to a twist-beam rear axle with a Watt linkage. A top rocker arm of the Watt linkage is mounted on the motor vehicle body. The Watt linkage prevents the motor vehicle from oversteering during cornering. The damping bushes can be disconnected in part from wheel-guiding functions as the Watt linkage performs a major part of the wheel guiding functions, which leaves some freedom for designing the characteristics so as to significantly increase motoring comfort.
