Embodiment Construction

[0115] The drawings are of a schematic nature only and are only used for the understanding of the invention. The same elements have the same reference numerals.

[0116] The features of individual embodiments can be implemented in other embodiments as well. Therefore, they are interchangeable.

[0117] figure 1 The spring set 2 of the invention is shown in a first exemplary embodiment. The spring set 2 comprises a first support ring 4 , a second support ring 6 and a plurality of coil springs 8 arranged between the first and second support rings 4 , 6 .

[0118] The coil springs 8 can be formed as tension springs or compression springs and, in the embodiment shown here, are evenly distributed along the circumference of the two support rings 4 , 6 and are arranged spaced apart from each other. Furthermore, it can be seen that the support rings 4 , 6 have a circular opening 10 aligned with the central axis of each coil spring 8 . Between two such adjacent circular openings 1...

Abstract

The invention relates to a spring set (2) used in clutches and / or transmissions, comprising: a first support ring (4), a second support ring (6), which is arranged axially with the first support ring (4) spaced apart (parallel), and arranged between a first support ring (4) and a second support ring (6) and distributed along its circumference a plurality of coil springs (8), wherein the support ring At least one of (4, 6) is formed from a sheet metal strip (22) which is stamped and then bent into a ring shape and whose ends are permanently connected to each other. Furthermore, the invention also relates to a method for producing a support ring (4, 6) for a spring set (2) according to the invention, comprising the steps of: stamping a predetermined length (l) and a predetermined width (b) The sheet metal strip (22), introduces the spring seat (10, 68), introduces indentations in the longitudinal edge (26) of the sheet metal strip (22) while forming the ring, and connects the two axial ends.

Description

technical field [0001] The invention relates to a spring set for use as a restoring element for multi-disc clutches and applications with similar functions in clutches and / or transmissions, said spring set comprising: a first support ring and arranged axially with The first support ring is spaced apart from and parallel to the second support ring, and a plurality of coil springs are arranged between the first support ring and the second support ring and distributed along the circumference thereof. The invention also relates to a method for producing a support ring. Background technique [0002] Rings made of sheet metal and their production are known from various fields of application. For example, EP 0 765 101 A1 discloses a method for producing a flat friction ring comprising a support ring and a friction lining which is arranged on at least one support ring side and forms at least approximately radial oil grooves , and the friction lining is initially cut out from a fri...
