TORSIONAL VIBRATION DAMPER

The invention relates to a torsional vibration damper (10), particularly a dual mass flywheel, a belt pulley decoupler or a pulley damper, for damping torsional vibration in a drive train of a motor vehicle, with a primary mass (12) forming a peripheral receiving channel (14), and a secondary mass (20) that can be rotated in a limited manner in relation to the primary mass (12) by means of an energy accumulator element (16), particularly a torsion spring, the secondary mass (20) comprising an output flange (18) projecting into the receiving channel (14) for tangential fastening to the energy accumulator element (16), the output flange (18) comprising a transmission flange (28) that is tangentially arranged on the energy accumulator element (16) and a connection flange (30) coupled to the transmission flange (28) by means of an additional damper (34) in such a way that torque can be transmitted, a toothing (32) being embodied particularly between the transmission flange (28) and the connection flange (30) and
