Abstract
1,251,708. Friction clutches. G.K.N. BIRFIELD TRANSMISSIONS Ltd. 11 May, 1970 [27 May, 1969], No. 26607/69. Heading F2C. To ensure that the spring means in a spring- engaged friction plate clutch exerts a substantially constant engaging force, and hence that the release pressure remains constant throughout the range of wear of the clutch, the spring means includes a first spring, e.g. a coil spring, exerting a thrust which increases with its compression and a second spring, e.g. a Belleville type dished washer, selected to operate over that range in which the thrust decreases with increasing compression. As shown, the springs 18, 21 act to separate the pressure plates 16, 17 in a dual clutch. The pressure plate 16 is moved to release the clutch by levers 27 pivoted at 29 and connected to the plate by links 34. Plate 17 is controlled by a second set of levers (28), Fig. 2a, (not shown), each carrying a roller (36) abutting a stud (37) on the plate to move it axially.
