Abstract (en)

[origin: WO2014094762A1] A vibration damper (100) comprises an input side (105), an output side (115), one or more elastic elements (130, 135) for force transmission between the input side and the output side, and a centrifugal pendulum having a pendulum flange (140) and one or more pendulum masses (145) which are movably mounted on the pendulum flange in the rotation plane of the pendulum flange. The invention proposes forming certain ratios of masses and volumes of the elastic elements and pendulum masses. If one or more of the ratios lie within specified ranges, efficient damping or absorption of torsional vibrations by the vibration damper can be assumed.
