Embodiment Construction
[0017] Embodiments of the present invention are as follows:
[0018] When the present invention is in a static state, the slider stays at the uppermost position by the hydraulic oil sealed in the annular return cylinder. The compression piston 3 is under the action of the 0.2MPa low-pressure oil at the bottom of the compression cylinder, so that the clutch driving plate and the driven plate are in a loose state. When starting, the electromagnet 13-12 is energized, and the electromagnetic suction presses the pilot spool 13-8 tightly on the aperture 13-11 through the control valve 13-9. At the same time, the return cylinder 12 discharges oil to the oil tank of the hydraulic oil supply system through the oil inlet and outlet ports 10, the slide block 9 falls freely under the action of gravity, and the screw rod 5 is driven by the nut 8 to rotate forward and accelerate. After a certain time delay, the hydraulic system enters the oil through the oil inlet 13-10 of the valve seat 1...
