Abstract

A vibration damping having a first torsional vibration damper couplable to a drive member with a first secondary side rotatable with respect to the first primary side against a return action of a first damper element arrangement, a second torsional vibration damper with a second primary side connected to the first secondary side and with a second secondary side rotatable with respect to the second primary side against the return action of a second damper element arrangement and couplable to an output member, and a deflection mass pendulum arrangement having at least one deflection mass. The first damper element arrangement has a plurality of first damper element units acting parallel to one another and/or the second damper element arrangement has a plurality of second damper element units acting parallel to one another.
