ABSTRACT:
A hydraulic clutch includes drive friction discs rotatably mounted around an output shaft, driven friction discs mounted around the output shaft against rotation relative thereto, a clutch pressure member mounted around the output shaft for movement therealong relative to a chamber plate fixedly mounted on the output shaft, the pressure member cooperating with the chamber plate to form a hydraulic pressure chamber. The drive and driven discs are movable along an axis of the output shaft. The pressure member has outlet port means communicating with the hydraulic pressure chamber. A clutch lifter member is mounted around the output shaft for movement therealong and is normally urged by urging means against the clutch pressure member to close the outlet port means. Fluid passageway means is connected to a source of pressurized fluid and communicates with the hydraulic pressure chamber for supplying the pressurized fluid thereinto to increase a pressure therein to urge the clutch pressure member toward alternately-disposed drive and drive friction discs, which are to drivingly couple them, thereby transmitting the rotation of said drive discs to the output shaft. Actuator means is operable to move the lifter member away from the clutch pressure member against the bias of the urging means to open the outlet port means to discharge the pressurized fluid therefrom to reduce the pressure in the hydraulic pressure chamber, so that the clutch pressure member is moved away from the drive and driven friction discs to discouple them.
