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.

A vibration damping device for a motor vehicle, features a first movable element (13, 14) and a second movable element (15, 16) both rotatable around an axis X, at least one group of elastic members (25, 26) mounted between the first movable element and the second movable element and acting against rotation of the first movable element and second element with respect to one another, and a phasing member (32, 33) rotationally movable around the axis X. The first movable element (13, 14) and the second movable element (15, 16) are coaxial and capable of transmitting a torque. The phasing member (32, 33) includes a first portion (32) and a second portion (33), for arranging the elastic members of the at least one group in series so that the elastic members of each group deform in phase with one another.

A damper device includes a first rotor, a second rotor, an elastic coupling part elastically coupling the first and second rotors in a rotational direction, and a hysteresis generating mechanism. The hysteresis generating mechanism generates a hysteresis torque and includes a friction member. The friction member is configured to make frictional contact with the first or second rotor. The friction member does not make frictional contact with the first and second rotors in a first torsion angular range where torsion is caused from a neutral condition to a first side and a second side in the rotational direction. The friction member makes frictional contact with the first or second rotor so as to generate a hysteresis torque in a second torsion angular range exceeding the first torsion angular range. The friction member is set in a neutral position by actuation of the elastic coupling part in the neutral condition.
