FRICTION DEVICE FOR A TORSIONAL VIBRATION DAMPER
The invention relates to a friction device (20) for a torsional vibration damper (10), comprising at least two friction elements (26) which can be moved independently of each other at least in the circumferential direction about a main rotation axis (14) and can be actuated via a primary-side control (28), and complementary secondary-side friction surfaces (30) which can be actuated via a secondary-side control (32) and on which rests in each case a friction element (26) with friction. The invention further relates to torsional vibration dampers and to a method for mounting a friction device of a torsional vibration damper.
