Abstract:
1. A suspension device for the load-bearing and resilient support of a wheel in a motor vehicle, comprising at least one spring cylinder with a piston, which is guided in a manner moveable relative to a pressure cylinder, and comprising a driving device including a gearwheel mechanism for converting pivoting movements of a wheel oscillating-crank supporting arm, which movements oscillate about an oscillating-crank axis, into the relative movements between the pressure cylinder and the piston, the piston acting counter to an elastically compressible spring medium (FM) in order to produce a load-bearing supporting spring force (F), the suspension device further comprising a damping device for damping the suspension movements, the damping device having a separate circuit of a hydraulic damping medium (DM), which circuit is independent of the spring cylinder and the spring medium (FM), the damping device has at least one damper cylinder having a damper piston which is guided in a manner moveable relative to the damper piston in the damper cylinder, and at least one damper valve, which is connected hydraulically to the damper cylinder, and wherein the damping device interacts with the same driving device as the spring cylinder.
