Device for damping vibration, particularly torsional vibration damper or dual-mass flywheel, has friction damping unit that is arranged between primary part and secondary part and produces counter force to normal force in friction device

摘要

The device (1) has a primary part (3) and a secondary part (4), which are limitedly rotating relative to one another in circumference direction. The primary part and the secondary part are coupled to each other by a spring and damping coupling. The secondary part comprises a central part (6), which is firmly connected with a connecting element. A friction damping unit (15) is provided, which is arranged between the primary part and a secondary part, and has a friction device (14) and an equipment (16) for producing a counter force to normal force in the friction device.
