Vibration damping assembly for a pulley that drives an auxiliary unit of a motor vehicle

摘要

Disclosed is an assembly for damping vibrations on a wheel that is used for driving a secondary unit of a vehicle. Said assembly comprises a damping device on the driving wheel that is mounted on a hub which is connected to a drive shaft of the secondary unit. A torsional vibration damper that is combined with a friction clutch is provided as a damping device. The friction clutch is fitted with at least one friction surface facing the hub and at least one second friction surface facing the friction ring in order to non-positively and/or positively couple the driving wheel to the hub via the damper cage of the torsional vibration damper such that torque is transmitted in a vibration damping manner from the driving wheel to the hub via the damper cage. The second friction surface is located between a plate spring and a support disk. The plate spring is connected to the damper cage while the support disk is connected to the hub. Also disclosed is an assembly encompassing several combined torsional vibration dampers. In addition, an assembly with fixed stops can be provided for transmitting high starting torques. Finally, an additional friction damping device is supplied on an assembly.
