Abstract
An arrangement for vertically adjustably supporting an individual wheel carrier disposed by way of control arms or an axle beam on the body of a motor vehicle. An actuator is fastened on the vehicle body, constructed as a hydraulic motor with at least one pressure space. The actuator has a swivellable actuating shaft which acts upon the wheel carrier, its control arms or the axle beam, by way of a linkage which contains at least one lever arm. The lever arm, upon which the hydraulic actuator acts directly, is designed as a mechanical spring. Also, at least one loaded pressure space of the actuator is hydraulically connected by way of at least one return valve, with a less loaded or unloaded pressure space or a return flow. As an alternative or in addition to the return valve, the loaded pressure space can be connected to a hydraulic accumulator.
