Abstract
Abstract A vehicle wheel suspension arrangement which includes a wheel guide assembly having a transverse strut at least a portion of which is displaceable in a vehicle longitudinal direction and a form-rigid longitudinal strut. Bearing elements having a variable elasticity pivotally mount the longitudinal strut at the vehicle body with additional bearing elements of differing elasticities mounting the wheel guide assembly at a wheel carrier.
