Torsional vibration damper for motor vehicle, has coil spring forming surface cylindrically running around longitudinal axis at one of its end windings, and other spring including end winding with outer diameter that is larger than surface

摘要

The damper has an energy storage with two coil springs (8, 9), from which the spring (8) is partially held within a spring inner space that is formed by windings of the spring (9). The spring (9) forms a surface cylindrically running around a longitudinal axis at one of its end windings. The spring (8) has an end winding with an outer diameter that is larger than the cylindrically running surface in a non-installed condition.
