This relates to a clutch module of the kind comprising a mechanism (11), a clutch friction wheel (12), and a flywheel (13), the mechanism itself comprising a cover plate (14), a diaphragm (15) which engages on the cover plate (14), and a pressure plate (16A) on which the diaphragm (15) engages, while the flywheel (13) is constituted by a reaction plate (16B) which is similar to the pressure plate (16A), together with a support plate (27) on which the cover plate (14) is fixed. According to the invention, the pressure plate (16A) is thicker at its outer periphery than at its inner periphery. Applicable to clutch modules, especially for motor vehicles. |
