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.

Clutch disk comprising a centrifugal pendulum

A drive train is disclosed that includes an engine operable in a first engine operating state and a second engine operating state and a torsional-vibration damping system operatively connected to the engine. The torsional-vibration damping system includes a first torsional-vibration damper having a primary inertial mass and a secondary inertial mass, a second torsional-vibration damper, a first centrifugal pendulum arranged on the secondary inertial mass of the first torsional-vibration damper, and a second centrifugal pendulum arranged on the second torsional-vibration damper.

A centrifugal pendulum and a clutch disk with a pendulum flange provided thereon, rotational about an axis of rotation, and several pendulum weights distributed over the circumference and received on the pendulum flange in a pivotal fashion. In order to at least reduce noise development due to mass momentum of inertia acting here caused by the centrifugal pendulum, the pendulum flange is received on a rotational part, rotating on an axis of rotation, and a friction clutch is effectively arranged between the pendulum flange and said part.
