Torque transmission device for powertrain of combustion engine-driven motor car, has transmission element connected with secondary mass in torque-proof manner, and sealing element formed between vibration damper and transmission element

摘要

The device (100) has a torsional vibration damper (102) provided with a primary mass (112). An output-side secondary mass (114) is rotatable around a common axis (a) and limited based on the primary mass. A damper device (116) is arranged between the primary and secondary masses. The primary mass includes a flange part (122) that is firmly connected with an output-side cover part (124). A transmission element (104) is connected with the secondary mass in a torque-proof manner. A sealing element i.e. two piece seal, is formed between the damper and the transmission element.
