Suspension and damping device for motor vehicles
Abstract:
The invention relates to a suspension and damping device (1) for load bearing and sprung wheel support and for damping suspension movements in a motor vehicle, having at least one spring cylinder (2) having a piston (6) which is guided in a cylinder (4) so as to be movable relative to the cylinder and which acts counter to an elastically compressible spring medium (FM) in order to generate a load bearing supporting spring force (F). A separate circuit of a hydraulic damping medium (DM) which is independent of the spring medium (FM) is provided for damping. The piston (6) separates two working chambers (10, 12) from one another within the cylinder (4). One working chamber (10) is assigned to the spring medium (FM) and the other working chamber (12) is assigned to the damping medium (DM).
