Abstract
Abstract A wheel suspension for driven wheels, especially rear wheels of a motor vehicle, by means of approximately triangular tilted control arms. Each of the control arms includes a longitudinal control arm and a transverse control arm, the transverse control arm is articulated on. The vehicle side opposite to the respectively associated wheel supported by the tilted control arm beyond a longitudinal center axis of the vehicle to the vehicle superstructure. A tilted control arm carries an axle gear mechanism connected to the wheel carried by this tilted control arm through a jointless shaft. The wheel of the other tilted control arm is connected to the axle gear mechanism through a jointed or universal shaft.
