[0002] In order to overcome the need for manual operation to separate and close the crank arm of the mechanical clutch, the pressing force of the disc spring is very large when the crank arm is closed, and the manual force is also very large; the crank arm must be driven to separate through a joystick, and the joystick passes from outside the cab into the cab, resulting in poor sealing of the cab; the friction plate will wear after a period of use, and the self-locking rod will not reach the self-locking point after wear and will bounce off, causing the driven disc and the friction plate to separate, resulting in slippage or causing the friction plate to burn out. In order to overcome the above shortcomings, a hydraulic clutch has been developed, for example, Publication No.: CN 115875376 A, Name: A hydraulic clutch, which discloses that the movement of the oil cylinder is driven by hydraulic oil, the oil cylinder drives the driven disc to move, the driven disc is combined with the friction disc device, drives the input shaft to rotate, and thus drives the pulley to rotate. The hydraulic structure disclosed in this technical solution is more labor-saving than a mechanical clutch.

[0003] However, the flywheel of the hydraulic clutch is inside the housing, and the disassembly process of the flywheel connection with the power system is relatively difficult, and only specific models of devices can be connected; secondly, in the prior art, the reset spring used to control the reset movement of the driven disk has not disclosed a specific fixing method. Since the spring is easily changed in position after being compressed, the reset of the driven disk becomes more difficult or cannot be reset.

[0004] Therefore, there is an urgent need for a hydraulic clutch with easy flywheel installation and reliable reset of the driven disc. Utility Model Content
