Abstract
A clutch assembly for selectively transferring rotary power between axially aligned drive and driven members arranged about a transmission shaft of off-highway equipment such as a tractor or the like. The clutch assembly includes an actuator assembly arranged in operable combination with a clutch pack of interleaved annular clutch plates. The actuator assembly includes a clutch piston arranged in operable combination with and establishing an expandable fluid receiving pocket with the drive member. The clutch assembly further includes an annular ring disposed in sealing engagement with and between the clutch piston and the drive member. As long as the clutch piston is in a released position, the annular ring operably divides the piston cavity into inner and outer annular cavities disposed at different radial distances from the axis of the shaft. The clutch assembly further includes a fluid conduit for delivering pressurized fluid to the piston cavity and that opens to the inner chamber of the piston cavity or pocket.
