A centrifugal pendulum includes a first flange, a first pendulum mass, and a first preloading element. The first pendulum mass is arranged on the first flange for movement in a radial direction relative to an axis of rotation and relative to the first flange. The first pendulum mass has an innermost point, an outermost point, a radial extension between the innermost point and the outermost point, and a first region arranged radially inward at most five percent (5%) of the radial extension from the outermost point. The first preloading element is arranged to contact the first pendulum mass in the first region for axially preloading the first pendulum mass with respect to the first flange.

Centrifugal pendulum

A torsional vibration damper () with a torque limiter includes an input part (), an output part (), and at least two torque-transmitting intermediate elements () arranged between the input part () and the output part () so as to move radially by cam mechanisms () in the case of a relative rotation of the input part () and the output part (). In the case of a relative rotation between the input part and the output part, a torsional characteristic curve () of a drive torque over the rotary angle has a damper stage () and an end stage () which adjoins the damper stage (), he damper stage () specifies a damper capacity of the drive torque over the rotary angle, and the end stage () includes a torque limitation of the drive torque over the rotary angle.

Torsional vibration damper with torque limiter

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 including an internal combustion engine with a crankshaft, and having a spur gear arrangement with at least one transmission input shaft that is coupled to the crankshaft by a friction clutch. A clutch plate within a housing of the friction clutch is connected in a rotationally locked manner to the at least one transmission input shaft and includes a centrifugal force pendulum. To accommodate the centrifugal force pendulum in the drive train in a space saving manner, the centrifugal force pendulum is situated on the at least one transmission input shaft at an axial distance from the clutch plate.

Drive train having a spur gearing and a centrifugal pendulum

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.
