ABSTRACT:
A friction clutch wherein the prestressed diaphragm spring has prongs extending outwardly from its annular main section and being separably affixed to the counterpressure plate by an annulus of screws. The spring bears against the pressure plate and urges the latter against the clutch plate which is thereby biased against the counterpressure plate. When the screws are removed, the prestressed spring is axially shifted relative to the pressure plate and lugs on its prongs come into engagement with a radial shoulder of the pressure plate to hold the spring against further axial movement relative to the pressure plate as well as to maintain the diameter of the circle formed by the centers of holes in the prongs at least substantially unchanged. This simplifies the reattachment of prongs to the counterpressure plate. The prongs tend to move radially inwardly and abut against a cylindrical surface of the pressure plate when they are detached from the counterpressure plate.
