Abstract
A friction clutch wherein the clutch spring is shiftable axially toward the pressure plate during disengagement of the clutch to compensate for wear at least upon the friction linings of the clutch disc. Disengagement of the clutch is facilitated by several springs which act upon the clutch spring and upon the pressure plate and render it possible to disengage the clutch in response to the application of a relatively small force to the tips of the radially inwardly extending prongs of the clutch spring. Moreover, the magnitude of the disengaging force remains at least substantially constant during the entire useful life of the clutch.
