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.
In a clutch assembly unit comprising an annular cover member and a pressure plate fixed to said cover member for rotation with and relative axial movement with respect to said cover member, resilient means interposed between said cover member and said pressure plate and normally tending to urge said pressure plate away from said cover member, a friction disc disposed between said pressure plate and a flat type reaction plate to be clamped therebetween;
A new article of manufacture comprising a clutch pressure plate assembly especially constructed for use with a flat type reaction plate said clutch pressure plate assembly including a cover member and a pressure plate conventionally assembled with said pressure plate in axial protruding relation with respect to said cover member for mounting on a reaction plate of the cup shaped or pot type, said cover member having a mounting flange with openings therein for fasteners to secure said cover member to a reaction plate, and spacing members fixed along said mounting flange in accordance with the position of said openings for spacing said mounting flange from a flat type reaction plate in accordance with said projection of said pressure plate with respect to said cover member.
