Abstract

A rear axle suspension for a motor vehicle with a wheel guide member retained directly at the wheel carrier which includes a first wheel-outer guide arm and a second wheel-inner guide arm. Both guide arms are pivotally connected at the vehicle body by way of elastic joints, whereby one joint of the first guide arm is constructed yielding longitudinally and together with the further elastic joint of the second guide arm forms an approximately transversely extending guide rotary axis and an imaginary wheel guide pole to the rear of the axis of rotation of the wheel and outside of the track width. The wheel guide member includes a spring strut connected with the guide body by way of a wheel-adjusting device which is constructed as part of a wheel inner guide member and is positioned obliquely to the vehicle longitudinal center axis. The spring strut has as part of the wheel inner guide member a smaller length than an adjoining rigid guide member part of the guide member. The spring strut is constructed to be elastically deflectable and retains the wheel-outer guide arm constructed in one piece with the guide body displaceable within limits by way of the control bearing support on the …
