Torsional vibration damper, particularly dual mass flywheel, has primary mass and secondary mass, which are coupled with each other in rotating manner by bow sheet arrangement

摘要

The torsional vibration damper has a primary mass (2) and a secondary mass (3), which are coupled with each other in rotating manner by a bow sheet arrangement comprising an inner spring (9) and an outer spring (8) opposite to the force of the bow sheet arrangement. A coil diameter is enlarged at an end of the inner spring such that this is greater than the inner diameter of the outer spring.
