Abstract
A clutch mechanism for a motor vehicle clutch comprises a cover plate and a diaphragm, which is mounted for pivoting deflection on the cover plate between a primary abutment carried by the cover plate and a secondary abutment formed on a crown ring. The crown ring is carried by assembly lugs which are joined to the cover plate, and which define a weakening groove of trapezoidal form. This weakening groove defines a bending line along which a terminal wing portion of the assembly lug is bent in an approximately radial direction. The weakening groove has two inclined side flanks. The inclined lateral flanks of each weakening groove are inclined with respect to the radial direction by different amounts, with the flank closer to the end portion of the assembly lug being inclined by a greater amount than the other flank which is closer to the cover plate.
