Powertrain for motor car, has attenuation device arranged parallel to powertrain for attenuating torsional vibrations and exciting impulse-like counter-rotational vibrations, where device is formed by clutch and partial drives

摘要

The powertrain (10) has an attenuation device (20) arranged parallel to the powertrain for attenuating torsional vibrations (16) of the powertrain and exciting impulse-like counter-rotational vibrations in the powertrain. The attenuation device comprises a torque transmission device for attenuation of the torsional vibrations, where the transmission device is provided with a powertrain-fixed delivering element, a device-fixed tap element and a clutch (24). The attenuation device is formed by the clutch and two partial drives (27, 28). An independent claim is also included for a method for attenuating torsional vibrations in a powertrain of a motor car.
