Abstract
Abstract An independent vehicle wheel suspension arrangement which includes a pair of control arms disposed in a superimposed relationship. The control arms are articulated to a wheel carrier and are selectively in a mutually parallel or non-parallel position. A wheel suspension unit is supported on the wheel carrier with a steering knuckle of the wheel being also articulated to the wheel carrier along the steering axis of the steerable wheels. The control arms are articulated to the wheel carrier by means of ball and socket joints and the wheel carrier is supported against a twisting about a substantially perpendicular axis of rotation determined by the ball and socket joints, with respect to the vehicle body, by an additional moment supporting arm. The moment supporting arm is likewise connected to the wheel carrier and the vehicle body by ball and socket joints.
