Embodiment Construction

[0025] figure 1 A drive train 1 of a motor vehicle is shown schematically. The drive train has a drive device 2 , which in the exemplary embodiment presented here is an internal combustion engine. The drive device 2 is operatively or operatively connected via a separating clutch 3 to a shaft 4 of a further drive device 5 , for example an electric motor. On the side of the other drive 5 facing away from the separating clutch 3 , the shaft 4 is connected to a transmission 6 , in particular a transmission. The shaft 4 thus appears as a transmission input shaft on the side of the drive 5 facing the transmission 6 . The transmission output shaft 7 is operatively connected to at least one wheel, not shown here, of a chassis 8 of the motor vehicle. It is obvious that the torque applied to the wheels and thus the driving of the motor vehicle can be carried out either only by means of the other drive device 5 or by engaging the separating clutch 3 by means of the drive device 2 and ...

Abstract

A centrifugal pendulum device includes a pendulum mass carrier, which is rotatable about a rotation axis, and at least one pendulum mass, which is supported on the pendulum mass carrier for movement along a track between end stops which are spaced from one another in circumferential direction in relation to the rotation axis. A spring device urges the pendulum mass in one of the end stops, when the rotation speed of the pendulum mass carrier drops below a limit rotation speed.

Description

technical field [0001] The invention relates to a centrifugal pendulum type vibration damping device, which has a pendulum mass support capable of rotating around a rotating shaft and at least one pendulum mass, the pendulum mass supported so as to be able to rest on the pendulum mass support along a working track Movement between two end stops on the shaft, said two end stops being circumferentially spaced from each other with reference to the rotation axis. The invention also relates to a drive train of a motor vehicle. Background technique [0002] Centrifugal pendulum dampers of this type are used, for example, in drive trains of motor vehicles in order to at least partially, preferably completely, absorb rotational vibrations induced by the drive of the drive train, in particular the internal combustion engine. Therefore, a centrifugal pendulum damper is used as a shock absorber. Unlike other dampers, the centrifugal pendulum damper can be tuned to defined orders over...
