VIBRATION DAMPER OF A VEHICLE WHEEL

WIPO Patent Application WO/2015/165910

A3

The invention relates to a vibration damper of a vehicle wheel, which vibration damper is supported on the vehicle body by means of a damper mount (2) having a rubber-elastic body (14) and which vibration damper has a fluid-filled cylinder and a piston, which is guided in the cylinder and has a piston rod (6), on both sides of which piston a damper chamber is formed, wherein a hydraulic pressure chamber (15) is formed in the damper mount (2), which pressure chamber is connected, by means of a fluid-conducting connection (12), to the damper chamber whose volume is reduced when the wheel is deflected in relation to the vehicle body. A throttle valve (25, 26, 27) is provided in said fluid-conducting connection (12). The throttle valve has a valve body (29), which can be displaced against spring force in relation to a valve seat (31) and has a throttle bore (30). The damper chambers formed in the damper cylinder on both sides of the damper piston are preferably connected to each other hydraulically by means of an electric-motor-drivable hydraulic pump.
