ABSTRACT:
A wheel suspension for steerable wheels, especially front wheels of motor vehicles, with a wheel carrier supporting the wheel; an upper cross guide member and a tie rod displaceable in its longitudinal direction are pivotally connected at this wheel carrier. The lower cross guide member supporting the vehicle support spring is connected by way of a corner-rigid pivot joint with an intermediate member, at which in turn the wheel carrier is supported by way of a corner-rigid pivot bearing having approximately vertical axis and a possibility of displacement in the direction of this axis. The wheel carrier and the intermediate member are each pivotally connected with an approximately vertical tension rod. The tension rod is extended beyond its pivotal connection with the intermediate member. A strut extending obliquely to the vehicle longitudinal direction, as viewed in plan view, is pivotally connected with its one end at the thus formed extension while it is pivotally connected with its other end at the vehicle body. A far-reachingly translatory movement can be superimposed in this manner on the purely rotary movement of the wheel, from which results a center of rotation for the steering movement of the wheel which is displaced to the vehicle outside with respect to the real joint connections of the wheel carrier. Additionally drive and brake moments which are exerted on the wheel carrier, can be favorably introduced into the vehicle body by way of the strut in conjunction with a vertical support strut.
