Problems solved by technology

This can lead to an uneven tension distribution in the connecting strip geometry when clamping the clamp (e.g. the screw head) when clamping, which then leads to deformation of the diaphragm and thus negatively affects the functional efficiency of the multi-disk clutch

Abstract

A multi-plate clutch for a motor vehicle (11), having an inner plate carrier (14), an outer plate carrier (15) and at least one fixedly engaged with the inner plate carrier (14) Or the diaphragm group (16) on the outer plate support (15), the diaphragm group includes at least two diaphragms (17), wherein the diaphragm clutch has at least one spacer element (19), so The spacer element is configured as a partition and is arranged between the at least two membranes (17), the spacer element being arranged to space the membranes (17) evenly.

Description

technical field [0001] The invention relates to a disc clutch for a motor vehicle and a hybrid traction device with the disc clutch. Background technique [0002] AT 157623 B discloses a diaphragm clutch for automobiles, in which at least a part of the diaphragm is kept at a certain distance apart by an axially deformable elastic spacer element. These elastic spacer elements are deformable in the axial direction, in particular after installation, so that when the multi-disc clutch is disengaged, the distance between the diaphragms increases due to these elastic spacer elements. When the multi-disk clutch is closed, the elastic spacer elements can be compressed, which reduces the distance between the diaphragms when closing. [0003] DE 33 20 977 C1 and EP 0 190 571 A2 likewise disclose similar multi-plate clutches. [0004] DE 10 2008 006 155 A1 of the same type already discloses a disc clutch for motor vehicles with an inner disc carrier, an outer disc carrier and at leas...
