Abstract: In a motor vehicle chassis, at least one wheel suspension, which comprises a spring in the form of a coil spring, has associated therewith a hydraulic height adjustment device having a cylinder-piston arrangement which acts on a base point of the coil spring. The cylinder-piston arrangement can be supplied by a decentral hydraulic aggregate which is associated with the relevant wheel and comprises a storage container for hydraulic fluid and a hydraulic pump driven by an electric motor. At least the electric motor of the hydraulic aggregate is situated within the coil spring.

Abstract: A pressure medium system, particularly a hydraulic system, which includes at least one working cylinder (pressure medium cylinder) and at least one pressure medium line for the supply and/or discharge of the pressure medium whereby assembly and disassembly is made possible, especially in vehicles, without great (manufacturing) efforts and by economic production by using a detachable retaining clamp (6) which grasps the outside of a pressure medium coupling (3) and an end piece (5) of the pressure medium line (4), which may be inserted into the pressure medium coupling (3).

Abstract: A motor-driven radial piston pump assembly has its radial piston pump supported by a base section on one side thereof which likewise supports an electric motor for powering the pump which is supported on that same side coaxially. The electric motor and a hydraulic tank are directly connected to the base section, the motor being surrounded by a cylindrical-shaped motor housing forming an inner wall of the tank and being sealingly connected to the base section, the motor housing being closed by a cover on its outer end opposite the pump. Such arrangement is compact in that the electric motor is simply positioned directly on the base section and is almost completely surrounded by the hydraulic tank such that the separate motor housing of the electric motor can be of simple and light weight construction.
