ABSTRACT:
Disclosed is a hydraulic clutch mounted between a power source and an output shaft. The clutch includes a pump mechanism including a hollow housing assembly coupled to the power source and rotatably mounted on the output shaft and having hydraulic passages provided therein, a passive gear fixed to the output shaft, and at least one driving gear rotatably supported within the housing assembly and engaging for driving the passive gear; a valve member sleeved on the output shaft; a passage system provided among the output shaft, the pump mechanism and the valve member, and adapted to be flooded with a liquid coming from a liquid source; and a control mechanism adapted to optionally control the hydraulic clutch either to become a dynamically connected state wherein the output shaft is dynamically connected to the power source by interrupting the passage system to establish a sufficiently high hydraulic pressure within the housing assembly and around the driving and passive gears, or to become a dynamically disconnected state wherein the output shaft is disconnected from the power source by opening the passage system to release the established hydraulic pressure within the housing assembly.
