Torsional vibration damper for arrangement between internal combustion engine and electric motor in hybrid drive train of motor vehicle, has first damper stages arranged radially within second damper stage and connected in parallel state

摘要

The torsional vibration damper (1) has energy storage unit (4) with two damper stages (10,13) that limits rotation of output unit (3). Two coil springs (11,12) are provided in damper stage (10), while bow springs (14) are fitted at damper stage (13). The damper stage (10) is arranged radially within the damper stage and connected in parallel state, such that damping stages (10,13) are switched simultaneously at large rotational angle of the input and output portions.
