ABSTRACT:
A variable speed drive unit having a clutch disc stack including input and output shafts, a first series of drive plates located in a fluid reservoir and supported for rotation by a rotatable housing of the unit rotated by one of said shafts, a second series of driven discs interleaved with the drive plates and supported for rotation with the other of said shafts, a piston slideably movable in a piston chamber located at one end of the interleaved plates and discs and adapted to compressively engage the interleaved plates and discs, and a control for the piston providing a gradually increasing rated profile without the need for electronic back-up or extraneous controls. The control includes a two position input flow control and a fixed output flow control, comprising a series of plugs, which output control can be selectively varied between operations of the unit to provide alternate rate profiles for engagement and disengagement of the input and output shafts of the unit.
