Torsion vibration damper arrangement for hydrodynamic torque converter of drive train of vehicle, has damper spring unit extending in circumferential direction, and damper spring asymmetrically formed in spring longitudinal direction

摘要

The arrangement (10) has a secondary side (24) rotated around a rotation axis with respect to a primary side (16) against the effect of a damper spring arrangement (32). The damper spring arrangement includes a damper spring unit (34) that extends in a circumferential direction. The spring unit has a damper spring (36), which is supportable at circumferential end areas (40) with respect to the primary side and the secondary side. The damper spring exhibits two areas for the damper spring unit, and the damper spring is asymmetrically formed in a spring longitudinal direction.
