Torsional vibration damper i.e. two-mass flywheel, for use between internal combustion engine and gear box in drive train of motor cars, has support parts and flange part that are axially overlapped at torque transfer regions

摘要

The damper (1) i.e. two-mass flywheel (2), has a flange part (13) acting upon a spring device (9), and a torque limiting device (16) arranged between the spring device and an outlet part (6). The flange part is accommodated between a support part (14) and another support part (18) i.e. flywheel mass (7), to form the limiting device, where the support parts are connected together. The support and flange parts are axially overlapped at torque transfer regions (20-23), where the regions are axially pretensioned together, axially flexible and distributed over circumference.
