Torque transmission device e.g. torsional vibration damper, for powertrain of motor car to attenuate torsional vibrations, has shock absorber device comprising energy storage part between output portion and another energy storage device

摘要

The device has an input portion and an output portion with a common rotational axis about which the input portion and the output portion are rotatable together relative to each other. A shock absorber device comprises an energy storage part between the input portion and the output portion, and another energy part device between the output portion and the former energy storage device dependant on a load. The output portion comprises a flange part (100) and a retainer for the latter energy storage part, where the retainer is radially inwardly arranged at the flange part. The energy storage device is designed as an auxiliary spring (102). The retainer is designed as a spring window (112).
