Vehicle wheel suspension of control blade design

Abstract

A vehicle wheel suspension of a control blade design has three wheel-guiding control arms essentially oriented in the transverse direction of the vehicle and one longitudinal control arm fastened rigidly to the wheel carrier and barely limiting its transverse movement with respect to the vehicle body. The longitudinal control arm is constructed of a fiber composite material and is also rigidly fastened to the vehicle body and thereby takes over the function of a main spring between the wheel carrier and the vehicle body. Other than stop springs integrated in a vibration damper, no further main spring element is provided between the wheel carrier and the vehicle body. The above-mentioned longitudinal control arm may be formed by two, in a wide area, individual control arm parts, which are essentially situated in a common vertical plane, specifically such that the first control arm part of the longitudinal control arm is fastened to the wheel carrier above the wheel center, and second control arm part is fastened to the wheel carrier below the wheel center. The two control arm parts, guided together with their other ends in a common fastening element, are, as required, slightly elastically fastened to the vehicle body.
