Abstract

At least three retraction springs (11) are mounted equally spaced, externally, between the outer edge of the cover (7) and the rim of the pressure plate (5), passing through windows in the cover. These springs instantly cause disengagement on declutching, since they act in opposition to the diaphragm force. The washer (12) of the thrust bearing is connected to the diaphragm via projecting tongues (12a) which are curved inwards and located in radial slots (8a) in the diaphragm. The tongues are retained on the other side of the diaphragm by an expansion ring (14). All play between thrust washer and diaphragm is taken up by an elastic mounting. The clutch plate is driven directly by the cover, which is rigidly fixed to the flywheel.
