Torsional vibration damper

摘要

The device (1) has a primary flywheel mass (2) connected with an output shaft of a drive unit e.g. internal combustion engine. A secondary flywheel mass (4) is twisted against the resistance of two energy storage devices relative to the primary flywheel mass. The secondary flywheel mass has a plate spring (28) as a catch spring, where a coupling unit (26) is attached at the plate spring. The coupling unit is arranged in an axial direction between contact surfaces of friction units that are loaded in the axial direction by the coupling unit.
