975,156. Damped resilient couplings. DANA CORPORATION. Sept. 21, 1961 [Sept. 30, 1960], No. 33895/61. Heading F2U. Clutch-plate torque-cushion springs 70 are arranged so that one parallel pair acts in series with another equal or unequal parallel pair, whereby the total deflection under a given load is four times that obtained with all four springs in parallel. For this purpose registering spring- receiving slots are provided in a driving clutch plate 12, intermediate outside plates 52, 54, and a driven hub plate 36. One diametrically opposed pair of slots 26, 28 in the drive plate 12 are long, the other 22, 24 short, and the pairs register respectively with similar short 40, 42 and long 44, 46 pairs of slots in the driven hub plate 36. All the slots 56 in the intermediate outside plates 52, 54 are short, and these latter plates are held together by spacer rivets 64 passing through slots 30, 48 in the driving and driven discs to allow the plates limited circumferential freedom. Under torque load the drive from the plates 12 passes through the springs in the short slots 22, 24 to the intermediate plates 52, 54 and thence through the springs in the short slots 40, 42 to the driven hub. Belleville-loaded friction washers 67, 69 and 50 provide damping. |
