Device for compensation of torque fluctuations of crankshaft of combustion engine in drive train of motor vehicle, has energy storage exerting compressive force on cam such that force generates moment around rotational axis of shaft

摘要

The device has primary and secondary masses (1, 2) periodically rotatable opposite to each other based on a shaft angle. An energy storage (14) exerts compressive force on a cam, which is connected with the shaft, such that the compressive force generates moment around a rotational axis (R) of the shaft. A housing-fixed bearing (11) is arranged at a distance (a) from a rotary axis of the primary mass. The energy storage is connected with a pressure unit (7) that is displaceable along an axle (16) and in contact with the cam.
