A compact torque limiting clutch (10) provides spring cup bolt assemblies (34) for interengaging a pressure plate (32) and input flange (12) on opposite sides of a friction flange (26) of an output hub (16). The spring cup assemblies (34) include bolts (40) employed for securing the clutch elements together, such bolts being restricted from rotating during the assembly process by engagement with noncircular apertures (58) passing through a retainer plate (56). The torque limiting clutch (10) is of pancake design, contained between axially displaced planar surfaces defined by an input flange (12) on one side and a pressure plate (32) on the other. In another embodiment of the invention, a keeper plate (113) is coaxially secured to an output hub (104) with a friction disc (106) fixedly secured therebetween. An input drive flange (102) is rotatably mounted on the keeper plate (113). A separator disc (122) extends the full diameter of the clutch assembly and has cup-shaped shields (124, 126) extending therefrom, serving as seals and heat dissipating members. Torque pins (138) pass through a pressure plate (116) which is urged toward the input hub (102) by a plurality of spring cup bolt assemblies (34), the torque pins serving as indicators of clutch wear. <IMAGE> |
