[0020] The piston is located in the hydraulic cylinder 5 and reciprocates under the action of oil pressure, and the movement of the piston realizes the engagement and separation of the clutch.

[0021] The pressure rod 2 is movably connected with the sliding sleeve 3, and the sliding sleeve 3 rotates together with the transmission shaft when engaged.

[0022] The hydraulic cylinder 5 is supported on the planetary reducer 12 through a support.

[0023] When high-pressure oil liquid is delivered into the hydraulic cylinder 5, the piston moves outward under the action of oil pressure to push the pressure rod 2 to drive the sliding sleeve 3.

[0024] The working principle and use process of the hydraulic clutch are as follows: the hydraulic clutch is mainly composed of a hydraulic cylinder 5, a pressure rod 2, a sliding sleeve 3, a sliding clutch 4 and a fixed clutch 1.

The clutch hydraulic control system is mainly composed of the hydraulic pump 8, the hydraulic cylinder 5, the electromagnetic switch valve 11 and a series of hydraulic pipelines;

[0026] The hydraulic pump provides power to press hydraulic oil 5 into the hydraulic cylinder 5 to drive the action of the clutch. The electromagnetic switch valve 11 plays a role in adjusting the hydraulic flow direction and pressure to ensure the stable operation of the clutch.
