Embodiment Construction

[0023] Figures 1 to 5 The flange 1 is shown in different views, in particular a flange for a torsional vibration damper. The flange 1 has an annular base body 2 which is provided with openings 3 on the circumference in order to connect the flange 1 to a further component, for example a torsional vibration damper. In this case, the opening 3 is used, for example, for riveting with further components of the torsional vibration damper.

[0024] The tongue 4 protrudes radially outwards from the annular base body 2 of the flange 1, wherein, in Figures 1 to 5 In the exemplary embodiment of the present invention, two tongues 4 protrude radially outward from the annular base body 2, said tongues protruding from the annular base body 2 offset by 180° relative to each other. In an alternative embodiment, the number of tongues 4 can also vary, eg in particular three, four or more tongues 4 can be provided. In another configuration, for example, only one tongue 4 can also be provided...

Abstract

The invention relates to a flange (1) having an annular main part (2) and tongues (4), which project radially outwards, for abutting energy accumulators, in particular torsional vibration dampers, the contour of the tongues (4) being designed such that it is Z-shaped in cross-section.

Description

technical field [0001] The invention relates to flanges, in particular flanges for torsional vibration dampers of internal combustion engines. Background technique [0002] In the prior art, torsional vibration dampers have an input part and an output part, wherein a spring is arranged between the input part and the output part, so that the input part can be twisted relative to the output part against the restoring force of the spring. [0003] Flanges are often used as input or output or in addition to one of these structures, which flanges have tongues on the radial outside, which engage in each case between two springs and act upon said springs when twisted. In the prior art, the flanges are made of flat sheet material. In this case, the flange is dimensioned in such a way that the material thickness is selected such that it is sufficient for the requirements of the most loaded regions. However, this leads to overdimensioning of the flange in less demanding areas. Con...
