  • Publication number: 20150224841
    Abstract: A wheel suspension for the rear axle of a vehicle includes a wheel carrier that is steerable in a pivoting range for mounting a wheel, and a plurality of control arms for articulating the wheel carrier to the body of the vehicle, and further a damping device for damping a movement of the wheel carrier relative to the vehicle body. The damping device is connected to the wheel carrier by way of a wheel carrier connection, wherein the wheel carrier connection is arranged in an attachment area of the wheel space of the wheel defined by the pivoting range of the wheel carrier, which, of all areas of the wheel space facing the vehicle body, has the greatest direct distance to the vehicle body.

  • Patent number: 8646787
    Abstract: A wheel suspension for a rear wheel of a motor vehicle includes a wheel carrier, a lower control arm and a track rod connected to the wheel carrier at first and second points of articulation and supported on a vehicle body by first and second bearings. A rotation movement by the control arm and the track rod in response to longitudinal and/or lateral forces causes a toe-in change to thereby adjust the first point of articulation of the control arm by a first transverse offset in a vehicle transverse direction and adjust the second point of articulation of the track rod by a second transverse offset in the vehicle transverse direction. The first bearing is configured elastokinematically such that the first transverse offset of the first point of articulation is greater than the second transverse offset of the second point of articulation in response to the longitudinal and/or lateral forces.
