Abstract

An individual wheel suspension for a non-steered wheel of a motor vehicle such as an automobile comprises a trailing arm including a lengthwise arm directed along the length of the vehicle, the trailing arm being articulated to the vehicle body by means of the lengthwise arm as well as two wishbones which are arranged transversely to the length of the vehicle and are located one above the other wherein at least the articulation of the lengthwise arm is an elastic bearing. The suspension is characterized in that the articulation of the lengthwise arm is disposed in the vicinity of the wheel center plane with the articulations of the wishbones on the body side being on one side of the wheel axle as viewed from above, and in that the articulations of the wishbones on the wheel side as viewed from above lie approximately on an auxiliary tie rod which runs centrally through the articulations of the wishbone on the body side and at least approximately through the intersection of the application lines of the force along the wheel and laterally with respect to the wheel. Wherein, the articulation of the lengthwise arm to the vehicle body is an elastic bearing with different spring rates C.…
