Abstract

A wheel suspension for the rear wheels of a motor vehicle is created, with three links being provided in an upper link plane, and with a foremost link as viewed in the direction of travel being provided as a track rod and the two further links being provided as separate individual links at both sides of a vertical wheel central transverse plane. A triangular link is arranged in the lower link plane, which triangular link holds a spiral or air spring and a damper strut spaced apart from one another. By corresponding pole formations defined by the links, elastokinematic or imaginary pivot axes are formed, which permits an elastokinematic adjustment of the wheel in a toe-in sense under the influence of braking forces, side forces and load shift forces. The wheel suspension is also configured such that an elastokinematic adjustment of the wheel in a toe-out sense is obtained in the event of wheel loads and drive forces.
