摘要： A rear axle of a two-track vehicle, including three control arms articulated to a wheel carrier and extending substantially in a transverse direction of the vehicle, and a trailing arm rigidly connected to the wheel carrier and having adequate flexibility in the transverse direction of the vehicle due to its structure or its mounting on the vehicle body. A support spring proportionately supporting the vehicle body with respect to the wheel and a vibration damper connected effectively in parallel with the supporting spring are supported on the wheel carrier without the intermediate arrangement of a control arm articulated to the wheel carrier. The support spring is supported in front of the wheel center and below the wheel center, as viewed in the direction of travel, on a cantilever protruding from the wheel carrier toward the vehicle center plane and the control arm articulated to the wheel carrier above the center point of the driven wheel in the vertical direction is connected to the wheel carrier behind the wheel center as viewed in the direction of travel. The control arm articulated to the wheel carrier in front of the wheel center as viewed in the direction of travel is connected to the wheel carrier below the wheel center in the vertical direction. The control arm arranged farthest to the rear as viewed in the direction of travel is connected to a steering actuator for the wheel by its end facing away from the wheel carrier.

摘要： 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.

摘要翻译： 控制刀片设计的车轮悬架具有基本上在车辆的横向方向上定向的三个车轮引导控制臂，并且一个纵向控制臂刚性地紧固到车轮支架上，并且几乎不限制其相对于车身的横向移动。 纵向控制臂由纤维复合材料构成，并且刚性地固定在车身上，从而承担了主轮之间的载轮与车身之间的功能。 集成在振动阻尼器中的止动弹簧除了在轮架和车身之间没有设置另外的主弹簧元件之外。 上述纵向控制臂可以由广泛的区域中的两个单独的控制臂部件形成，这些控制臂部件基本上位于共同的垂直平面中，特别地使得纵向控制臂的第一控制臂部分被固定到 轮架在车轮中心上方，第二控制臂部分固定在轮毂下方的车轮中心。 根据需要，两个控制臂部件，其另一端被引导在公共紧固元件中，根据需要略微弹性地紧固到车体。
