Title: TORSIONAL VIBRATION DAMPER
Abstract:
The invention relates to a torsional vibration damper (10), in particular a two-mass flywheel, pulley decoupler or disc damper, for damping torsional vibrations in a drivetrain of a motor vehicle, comprising a primary mass (12) forming an encircling receiving channel (14) and a secondary mass (20), which, via an energy store element (16), in particular a torsion spring, can be rotated to a limited degree relative to the primary mass (12), wherein the secondary mass (20) has an output flange (18) protruding into the receiving channel (14) for tangential abutment against the energy store element (16), wherein the output flange (18) has a transfer flange (28) tangentially abutting the energy store element (16) and a connection flange (30) coupled via a clearance angle to the transfer flange (28) in such a manner that torque can be transmitted. As a result of the multi-part output flange (18), the realisation of the clearance angle can be relocated away from the radius area of the energy store element (16) into the output flange (18) such that a torsional vibration damper (10) with a soft spring characteristic line and a large clearance angle is made possible.
