Abstract: A damping system of an active chassis for a vehicle wheel. The damping system includes a double-acting hydraulic cylinder and a damper having a piston, which damper is couplable to a wheel suspension system for the wheel. A hydraulic pump has a hydraulic reservoir and a hydraulic unit including valves. The hydraulic pump and the hydraulic unit cooperate with hydraulic chambers of the hydraulic cylinder such that, depending on the direction of conveyance of the hydraulic pump of the hydraulic unit, a movement of the piston in a first direction of actuation or in a second direction of actuation can be provided. The hydraulic pump and the damper are connected via the hydraulic unit and a tube-hose system including tubes and hoses. The hydraulic cylinder of the damper and the tube-hose system of the damping system feature a combined hydraulic capacity of between 9 mL/100 bar and 14 mL/100 bar.

Abstract: Disclosed herein is a sway bar system comprising a damping link that couples a first end of a sway bar to a first location on a vehicle. The damping link is comprised of a body comprising a damping chamber and a reservoir. There is also a through shaft coupled to a piston, where the piston divides the chamber into a first chamber and a second chamber. A high-pressure line is fluidly coupled with the chamber and the reservoir and allows fluid to flow from the first chamber and the second chamber to the reservoir. A low-pressure line is fluidly coupled with the chamber and the reservoir and allows fluid to flow from the reservoir to the first chamber and the second chamber. The high-pressure line and the low-pressure line assist in self-centering the sway bar.

Abstract: In a motor vehicle chassis, all four wheel suspensions each have associated therewith a hydraulic height adjustment device having a cylinder-piston arrangement which acts on a base point of the relevant spring and is supplied by a decentral hydraulic aggregate. The hydraulic height adjustment devices each comprise a complex, integrated electrohydraulic adjustment assembly comprising the allocated hydraulic aggregate and the associated cylinder-piston arrangement and having a specific adapter into which the allocated cylinder-piston arrangement is integrated in such a way that there are no exposed hydraulic lines between the allocated hydraulic pump and the associated cylinder-piston arrangement. The front wheel height adjustment devices and the rear wheel height adjustment devices differ in terms of the adapter.
