Apparatus for vibration damping in a motor vehicle

摘要

Apparatus for damping vibration in a motor vehicle includes a vibration damper module having a hollow-cylindrical housing, which has opposite ends closed by force-transmitting end closures, and a control unit for detecting interfering vibration and generating a control signal in response to the detection of the interfering vibration. An actuator assembly is secured to an inside wall surface of the housing and rendered operative in response to the generation of the control signal for causing the vibration damper module to introduce into the motor vehicle a counter vibration to suppress the interfering vibration. The actuator assembly includes at least three actuators distributed in the housing in spaced-apart relationship on a pitch circle and having a length extension which is aligned in parallel relationship to a length extension of the housing.
