摘要： A torque transfer mechanism includes an input member to receive an input torque from a propulsion source and an output member coupled to the input member to transfer the input torque to a driveline component. The torque transfer mechanism also includes a damping mechanism disposed between the input member and the output member having at least one clockspring coiled about a center axis of rotation to couple the input member to the output member. The at least one clockspring is arranged to damp vibration associated with the input torque and is coiled in multiple planes such that the clockspring does not contact itself under torsional deflection.

摘要： The invention relates to clutch disc comprising a torsional vibration damper which has an inlet part and an outlet part and a spring device operatively arranged in the peripheral direction between the input part and the output part, wherein the spring device is formed from the first and second spring elements connected behind one another and separated by an intermediate flange, and a centrifugal pendulum which has a pendulum mass carrier arranged about an axis of rotation of the clutch disc and pendulum masses accommodated on same on pendulum paths for oscillation and arranged in a distributed manner over the periphery. In order to improve the insulation effect of the torsional vibration damper and the centrifugal pendulum and/or better adjust same to the required application, the pendulum mass carrier is coupled for conjoint rotation with the intermediate flange and centrally accommodated on the output part.

摘要： A clutch friction disc includes a clutch damping system. The clutch damping system includes a pendulum body including first and second pendulum masses arranged on a support displaced rotationally around an axis. The clutch damping system also includes a rolling member to interact with a first raceway defined by the support and with a second raceway defined by the pendulum body. The clutch damping system also includes an interposition part including an interposition region having an axially facing surface interposed axially between the first pendulum mass and the rolling member to prevent contact in the axial direction between the first pendulum mass and the rolling member. The interposition part includes a fastening region to fasten the interposition part to the first pendulum mass. The fastening region includes at least two fastening tabs and a reinforcement rim extending from the interposition region to connect the fastening tabs.
