Embodiment Construction

[0085] Figure 3 to 7 The assembly 1 for a normally closed clutch device according to the first embodiment is shown. The assembly 1 includes an annular cover 2 having an axis X.

[0086] The terms "axial", "radial" and "circumferential" are defined by the reference axis X.

[0087] The cover 2 includes a radial portion 3 that includes a radially inner peripheral edge 4, and its outer peripheral edge is elongated by an annular portion 5 that extends axially. The cover 2 thus has the overall shape of a bell defining an internal volume. The free end of the axial annular portion 5 includes a radially outwardly extending flange 6 which is used in particular for the mounting of the cover 2 on a reaction plate, which is formed, for example, by an engine flywheel (not shown).

[0088] The radial portion 3 of the cover 2 includes a protruding support area 7 having the shape of a circular arc in a front view, which is uniformly distributed over the entire periphery and angularly offset from ...

Abstract

The invention relates to an assembly (1) for a clutch device, in particular for a motor vehicle, said assembly (1) comprising: a cover (2) having an axis (X); a pressure plate (8), It is movable relative to said cover (2) along said axis (X) and is induced by a diaphragm (9) interposed axially between said cover (2) and said pressure plate (8) movable, the diaphragm (9) is movable between an engaged position and a disengaged position; an elastically deformable auxiliary washer (29), which is inserted axially between the cover (2) and the diaphragm (9 ), and can exert a variable axial force according to the position of the diaphragm (9); it is characterized in that, when the diaphragm (9) is in the disengaged position, the auxiliary washer (29) can axially bearing radially on a link (24) fixed relative to said cover (2) to maintain said auxiliary washer (29) bearing against said cover (2).

Description

Technical field [0001] The invention relates to an assembly for a clutch device, particularly for a motor vehicle. Background technique [0002] In motor vehicles, the device is intended to rotatably couple an engine shaft (like for example a crank) and the input shaft of a gearbox. [0003] Generally, the clutch device includes a cover in which an annular diaphragm is housed, and the annular diaphragm is tilted between an engaged position and a disengaged position to move the pressure plate. The diaphragm respectively pivots around first and second supporting areas that extend circumferentially and are positioned on both sides of the diaphragm, the first and second supporting areas being between the diaphragm and the cover and between the diaphragm and the Between the pressure plates. The cover, the diaphragm and the pressure plate are rotatably connected. [0004] The annular diaphragm thus forms an articulated lever member, and at its radially inner periphery includes radial fi...
