Spring diaphragm for clutch mechanism of motor vehicle, has nozzles that surround central opening and form tracks that includes plane track forming interior radial track and convex track placed adjacent to plane track

摘要

The diaphragm has a conical elastic disc that is cut out in the interior to form radial fingers (12) resulting from an external crown of the disk. Nozzles of the disc surround a central opening (14) and form a track for a range of obstinate clutch. The nozzles have a plane track (13b) that forms an interior radial track and a convex track (13a) placed adjacent to the plane track. An Independent claim is also included for a clutch mechanism including a spring diaphragm.
