Abstract

A flywheel mass arrangement having a flywheel mass on the driving side, a planetary gear unit having at least one planet carrier provided with at least one planet gear that engages with at least one additional toothed wheel of the planetary gear unit, and with a flywheel mass on the driven side which can be rotationally deflected relative to the flywheel mass on the driving side. At least one of the flywheel masses has a control structure for elastic elements of a damping arrangement which act in the circumferential direction. A mass is provided at the planet gear to project radially beyond the toothing diameter of the planet gear and is arranged at an axial offset relative to at least one additional toothed wheel such as the ring gear or the sun gear of the planetary gear unit, in particular relative to the toothing engagement of the additional toothed wheel with the planet gear.
