Abstract
A clutch assembly is provided for selectively establishing a drive connection between a pair of relatively rotatable members. The clutch assembly includes a series of interleaved plates operably effective when axially compressed to couple the rotatable members. A fluid pressure operated clutch actuator is provided for effecting clutch engagement and regulating the torque carrying capacity of the clutch assembly. The clutch actuator includes an annular clutch engaging face area. The present invention contemplates arranging a series of deflectable springs between the annular face area on the clutch actuator and the interleaved plates to provide a gradual deceleration of the clutch actuator during clutch engagement in a manner significantly reducing impact loading and associated torque peak to the clutch assembly.
