Abstract

A wheel suspension for an axle of a motor vehicle has a transverse control arm and tension strut, the transverse control arm being held on the wheel carrier by way of a joint, and the body-side bearings of the transverse control arm and of the tension strut as well as of the connection bearing between the transverse control arm and the tension strut being constructed with a defined characteristic for the elastokinematic adjustment of the wheel under the effect of lateral and peripheral forces acting upon the wheel. The transverse control arm with the connected tension strut is arranged below a wheel drive shaft and--with respect to the driving direction--in front of a tie rod. In the top view, the tension strut extends diagonally toward the front, the transverse control arm and the tie rod having a positive position with respect to one another. They form a wheel steering pole situated outside the track width and behind the wheel center transverse plane. In front of the wheel center transverse plane and outside the wheel center longitudinal plane, a point of intersection is formed through an axis extending through the wheel-carrier-side joint of the transverse control arm and the bo…
