A special case of torsional vibration absorbers is the centrifugal pendulum, in the absorber masses on tracks with circumferential and radial portion are arranged displaceable, so that the absorber masses take different radii for torsional vibrations and thus the moment of inertia of the absorber mass receiving component increases and thus the component for a short time is slowed down.
  • The devices used in a powertrain to reduce of torsional vibrations are each adapted to the drive train. It has been found that the known arrangements of torsional vibration dampers in a dual mass flywheel and / or a disc damper one Clutch disc may not be sufficient to vibrations occurring in the drive train, by resonance of the torsional vibrations and / or be amplified by natural vibrations of the drive train can, sufficiently reduce.
