Problems solved by technology

However, this known technical solution necessitates the use of a clutch cover and an annular spacer specially designed for this purpose
[0010] [10] Furthermore, at the end of the normal disengagement stroke, the ends of the radial fingers actuated by the clutch stop abut against the annular stop formed by the radially inner peripheral portion of the clutch cover, which Interfering with the control of the clutch stop
Finally, the impact of the ends of the radial fingers of the spacer on the annular stop of the clutch cover tends to generate noise and damage the clutch mechanism and its controls

Embodiment Construction

[0032] [32] First refer to figure 1 , figure 1 A clutch mechanism with automatic wear compensation of the known type is shown schematically, for example as described in document FR 2847626-A1.

[0033] [33] The clutch mechanism mainly comprises an annular spacer 10, the radially outer part of which is formed by a diaphragm spring washer (rondelle Belleville) 12 supported on a clutch cover 14, the diaphragm spring washer It is fixed on the idler wheel 16 driven to rotate by the drive shaft 18 , and the idler wheel 16 is fixed to the drive shaft 18 by screws 20 .

[0034] [34] The annular spacer 10 axially urges the pressure plate 22 towards the idler wheel (volant d'inertie) 16, the pressure plate 22 forms the reaction disc of the clutch for fastening the friction lining 24, which is driven by the friction A disc 26 is supported, and the friction disc 26 is rotatably connected to a driven shaft 28 , for example an input shaft of a gearbox.

[0035] [35] The free ends of the ...

Abstract

A pressure clutch mechanism has an annular diaphragm (10) with an external radial annular part for soliciting a pressure plate axially to fasten the friction line of the clutch plate. The diaphragm (10) is pivoted on a clutch cover (14), which inludes a stop unit (44) for limiting the separation journey.

Description

technical field [0001] [01] The present invention relates to a power clutch mechanism, in particular for motor vehicles, comprising an annular spacer which urges towards the reaction plate (plateau de reaction). Dynamic pressure plate (plateau de pressure), a reaction plate driven in rotation by a drive shaft, such as the crankshaft of an internal combustion engine of a motor vehicle, to tighten a friction lining between the pressure plate and the reaction plate, the friction lining being rotated by A disc (disque) bearing connected to a driven shaft, such as the input shaft of a gearbox. Background technique [0002] [02] The annular spacer comprises: a radially outer annular portion, such as a diaphragm washer, which is supported on the cover of the clutch; and a radially inner annular portion, which consists of elastically deformable radial finger Formed as a body, said radial fingers extend towards the axis of rotation and are intended to cooperate with an axially displ...
