Patent ID: 7475761

Claim:
Apparatus for damping vibration in a motor vehicle; comprising: a control unit for detecting interfering vibration and generating a control signal in response to the detection of the interfering vibration; a separate vibration damper module for integration in a motor vehicle and including a hollow-cylindrical housing which has opposite ends, and end closures constructed for transmitting a force and respectively secured to the ends of the housing for sealing the ends of the housing; and an actuator assembly secured to an inside wall surface of the housing of the vibration damper module and extending between the end closures, said actuator assembly 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, wherein 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 aligned in parallel relationship to a length extension of the housing.
