Abstract:
A rotating clutch mechanism comprising:a rotatable input shaft;a rotatable piston drivingly connected with said input shaft and defining one axial extent of said clutch mechanism;a plurality of input friction plates drivingly connected with, axially moveable on, and spaced axially along said input shaft in axial alignment with said piston;an output member;a plurality of output friction plates drivingly connected with and axially moveable on said output member, and being alternately spaced with and axially aligned with said input friction plates, said input friction plates and said output plates defining a clutch pack;a backing plate drivingly connected with said input shaft defining an extent of said clutch pack and being axially aligned with said input friction plates, said backing plate having a recess formed thereon having first and second circumferential walls;a first retaining and locating ring secured in a groove on said input shaft to limit axial movement in one direction along said shaft; anda second retaining and locating ring secured in a groove in said second circumferential wall and having an inner periphery overlapping an outer periphery of said first retaining ring and cooperating therewith to retain said first retaining ring in overlapping relation with said first circumferential wall and thereby limiting axial movement of said backing plate in another axial direction.
