[0035] refer to figure 1 , The clutch master cylinder includes: a cylinder body 1 with a piston chamber 1a and a piston 2 located in the piston chamber 1a. The piston chamber part on one axial side of the piston 2 is a hydraulic chamber 1b, and the piston rod 4 is connected to the other axial side. The cylinder body 1 is provided with a first oil delivery part 11 communicating with the hydraulic chamber 1b, the outer peripheral surface of the piston 2 is provided with an oil groove 2a, and the cylinder body 1 is provided with a second oil delivery part 12 communicating with the oil groove 2a. An oil passage 2b is provided in the piston 2, and the oil passage 2b can communicate with the hydraulic chamber 1b and the oil groove 2a.
[0036] An on-off piece 3 may be provided outside the oil passage 2b. combine figure 2 , depress the clutch pedal, the piston rod 4 drives the piston 2 to move to the left, and the high-pressure oil in the squeeze hydraulic chamber 1b is output fr...
