<p>A friction clutch wherein the pressure plate at one side of the clutch disc is axially movably connected with a cover by a set of leaf springs which are disposed at the outer side of the cover, namely at the side which faces the engine of the motor vehicle wherein the clutch is installed. The cover is driven by the crankshaft of the engine and has raised portions extending toward the engine and being riveted to the respective end portions of the leaf springs. The other end portions of the leaf springs are riveted to protuberances which are provided on the pressure plate and extend into openings provided therefor in the cover and alternating with the raised portions. The clutch plate is biased against the adjacent lining of the clutch disc by a diaphragm spring whose radially outermost portion reacts against the cover radially inwardly of the protuberances and which bears against the pressure plate in a region which is located somewhat inwardly of the radially outermost portion. The protuberances of the pressure plate need not extend radially outwardly beyond the peripheral surfaces of the linings on the clutch disc. The leaf springs transmit torque between the cover and the pressure plate and allow the latter to move axially into and from frictional engagement with the adjacent lining. The mounting of such leaf springs at the outer side of the cover contributes to compactness of the friction clutch, as considered in the radial direction of the linings.</p> |
