Embodiment Construction

[0024] The invention is described in detail with the aid of a single figure. The figure shows a shortened arcuate energy store 1 which is installed, for example, in a dual-mass flywheel or another torsional vibration damper. it goes without saying, figure 1 The advantageous embodiments of are correspondingly also used for non-bending energy stores. In the exemplary embodiment shown, the energy store 1 has two helical springs nested inside one another, namely an outer spring 2 and an inner spring 3 . The two helical springs have two common end faces 4 , 5 which each have a differently shaped adhesive connection 6 , 6 ′ shown in an exemplary embodiment. It goes without saying that the adhesive connection 6 , 6 ′ can be implemented identically on only one end face or mixedly on both end faces 4 , 5 or uniformly on both end faces 4 , 5 . In the case of using an adhesive connection 6', this adhesive connection can also be at one place between the end faces 4, 5 between the two c...

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. ...
