ABSTRACT:
A control system for actuating various types of clutches includes a first piston which contacts a clutch disc associated with a first shaft. The first piston forces the first shaft clutch disc into a corresponding clutch disc associated with a second shaft. A second piston is received within a fluid chamber, and is reciprocated by a motor to force fluid outwardly of the fluid chamber and against the first piston. In this way, the position of the second piston controls the force of the first piston against the clutch disc of the first shaft. An electronic control for the second piston motor accurately controls the position of the second piston to control the force of the first piston on the clutch discs. The first and second pistons, the ball screw motor, the fluid chambers and the fluid paths are all received in a casing for the shafts. In this way, the size of the clutch is reduced over prior art assemblies which typically required a separate pump removed from the casing.
