Abstract

The invention relates to a torsional vibration damper having an energy storage acted between an input member and an output member and composed of at least two coil springs nested to each other. The coil springs are secured against each other in a material locking manner, such as by a glued connection in order to prevent lost between the two members before an installation.

Description

technical field

[0001] The invention relates to a torsional vibration damper with an input part and an output part with an energy store acting in the circumferential direction between the input part and the output part. Background technique

[0002] Such torsional vibration dampers are known from automobile construction and are installed in the drive train, in particular between the internal combustion engine and the transmission, in order to damp torsional vibrations caused in particular by rotational inhomogeneities of the internal combustion engine. The energy store is preferably formed here by helical springs, for example helical compression springs, which can be pre-bent in the case of a long embodiment for a simpler construction. In order to adapt the spring rate, a plurality of, for example two or three, helical springs can be nested within one another. In this case, the length of the helical spring can be varied in order to form a multi-stage characteristic curve. ...
