Abstract
The invention relates generally to an assembly unit for a clutch, especially for automobile vehicles, and comprising an annular cover, a pressure-plate fixed for rotation with the cover and movable axially with respect to this latter, an elastic diaphragm with controllable action interposed between the cover and the pressure-plate and tending especially to move this plate away from the cover, a friction-disc adapted to be coupled for rotation with a first or driven shaft, and a reaction-plate intended to be coupled to a second or driving shaft, the assembly unit being adapted for fixing by the periphery of the cover on the reaction-plate so as to effect a controlled gripping of the friction-disc between the pressure-plate and reaction-plate, the cover periphery comprising radial fixing zones; the cover is provided at positions along its periphery with spacing members which project from the fixing zones, these members being fixed permanently on the cover periphery and extending substantially radially, each spacing member having a supporting surface by which it is intended to come into contact with the associated reaction-plate.
