Clutch driven plate assembly with anti-backlash damping.

摘要

A clutch driven plate assembly for use in an automotive vehicle and having anti-backlash damping adapted to dissipate the irregular impulses of the vehicle internal combustion or diesel engine with the transmission in neutral, the clutch engaged and the engine at idle rpm. The assembly includes a clutch plate (31), a spring retainer plate (41) secured to the clutch plate, and a hub assembly (11) comprising an inner hub (121 in operative engagement with the transmission input shaft and an outer hub (18) having an integral hub flange (26) with spring windows (27) coinciding with the spring windows (33, 34) of the clutch and spring retainer plates. An intermeshing backlash spline (15, 22) loosely connects said inner (12) and outer (18) hubs to allow limited relative rotation therebetween and means yieldably resisting relative rotation of said hubs includes a plurality of circumferentially equally spaced recesses (16) in one hub and a plurality of plungers (47) and compression springs (51) in the other hub with the plungers biased by the springs into engagement with complementary recesses. Rota tion of the clutch (31) and spring retainer plates (41), damper springs (28) and outer hub (18) relative to the inner hub (12) causes the plungers (47) to be cammed out of the recesses against the force of the compression springs (51).
