Abstract
533,563. Friction clutches. BORG & BECK CO., Ltd. (Nutt, H., and Smirl, R. L.) Aug. 1, 1939, Nos. 11866/40 and 11870/40. Divided out of 533,506. [Class 80 (ii)] [Also in Group XXXII] A spring of the kind comprising a ring of sheet metal curved in radial section to the form of a dome has a " crown measurement " within 0.2 and 2 times the maximum thickness of the ring, the " crown measurement " being the maximum distance c, Fig. 10, between the. concave surface of the spring and a chord connecting the inner and outer peripheries. The spring may be formed with slits 166, Fig. 13, extending radially from the inner periphery to apertures 168.. The characteristics of the spring may also be modified by apertures 176, Fig. 17, pierced through the body of the spring, by providing the inner periphery with a reversely turned collar portion 182, Fig. 19, or by flattening off the intermediate portion 188, Fig. 22, of the convex side. Fig. 9 shows the application of the spring to a friction clutch, where a driver plate 120 is clamped between friction faces 122, 124 respectively of a flywheel and a pressure plate 126 by pressure developed in a spring 128. A series of levers 134 extend through and are fulcrummed against openings 140 in the clutch cover 132, their inner ends being engaged by a release bearing number 148 and their outer ends engaging bosses 144 on the pressure plate 126. The inner periphery of the spring is engaged by the control portion of the cover and the outer periphery by the levers. The first Provisional Specification describes the application of a spring constructed in accordance with the invention to a friction clutch described in Specification 533,506.
