Abstract

537,927. Friction clutches. GENERAL MOTORS CORPORATION. Feb. 8, 1940, No. 2419. Convention date, Feb. 27, 1939. [Class 80 (ii)] In a friction clutch comprising a flywheel 9, cover plate 13 fixed thereto and a pressure plate 19 for gripping a friction plate 25 between itself and the flywheel, the pressure plate is connected to the cover 13 by a number of U- shaped springs 53 which are stressed when the clutch is engaged, these springs serving to transmit drive from the cover to the plate 19, to centre the plate, and to withdraw the plate when the pressure of the main clutch closing spring is relieved. The pressure plate is actuated to close the clutch by a conical spring 31, such as a Belleville washer making circular line contact with a bulge 35 on the cover, an annular member 43 secured to the cover having a circular edge 51 which, when the clutch releasing device 57 is actuated, forms a fulcrum edge on which the spring turns to relieve the pressure on the plate 19. The member 43 has axially extending fingers 45, passing through openings 41 at the ends of slots 37 in the spring 31, and welded at 47 to the cover 13.
