A suspension of a vehicle axle is provided having a twist-beam axle that includes, but is not limited to two trailing arms, each of which have a wheel suspension and are interconnected via a cross brace with a torsion profile, which is designed stiff to bending and torsionally soft. The twist-beam axle connects to a Watt linkage of arrowed design, which articulates on the trailing arms laterally offset to an axis through a wheel center of the wheel suspension.

Suspension of a vehicle axle and vehicle

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.
