The oil adjusting mechanism 40 is used for adjusting the position of the engagement point of the clutch, the oil adjusting mechanism 40 includes an oil cylinder 401, a piston 402, a sealing ring 403, a spring pusher 404, a spring 405, a lead screw transmission mechanism 406 and a driving mechanism 407, the oil cylinder 401 has a cylinder body which is through along the axial direction, the two ends of the cylinder body are open, the initial open end of the oil cylinder 401, namely the left end of the cylinder body is communicated with the inside of the oil pipe 30, the piston 402 is slidably embedded in the oil cylinder 401 through the sealing ring 403, specifically, the sealing ring 403 is sleeved on the outer edge of the piston 402, so that an oil adjusting chamber 4011 from the initial open end of the oil cylinder 401 to the left end surface of the piston 402 is formed in the oil cylinder 401, the spring 405 is placed between the piston 402 and the spring pusher 404, the spring 405 is compressed by the piston 402 and the spring pusher 404 moving towards each other, the spring pusher 404 is preferably in a round block shape, the spring 405 may be connected with one or both of the piston 402 and the, the driving mechanism 407 drives the spring pushing element 404 to move axially in the oil cylinder 401 through the lead screw transmission mechanism 406, so as to control the position of the spring pushing element 404 in the oil cylinder 401, and with the help of the oil pressure generated by the primary end oil cylinder 10, the piston 402 is driven to move towards the spring pushing element 404 until the spring pushing element 404 and the spring pushing element are in contact with each other, so that the volume of the oil adjusting chamber 4011 changes, if the spring pushing element 404 moves leftwards to a certain position, the volume of the oil adjusting chamber 4011 decreases, and if the spring pushing element 404 moves rightwards to a certain position, the volume of the oil adjusting chamber 4011 increases.

The specific working mode of the oil regulating mechanism 40, the primary end oil cylinder 10, the terminal end oil cylinder 20 and the oil pipe 30 working cooperatively is as follows: first, when the driver steps on the clutch pedal to the limit position, the oil pressure generated by the initial cylinder 10 is transmitted to the final cylinder 20 through the oil pipe 30, and the final cylinder 20 operates to operate the swing member, thereby releasing the engagement of the clutch. While the clutch is disengaged, the driver operates the shift lever to shift the gear, and then the driver returns the clutch pedal to the home position, so that the hydraulic pressure of the final end cylinder 20 is absorbed by the primary end cylinder 10, and the clutch is reengaged to transmit the driving force of the engine to the drive wheels.

In returning the clutch pedal from the extreme position to the initial position, the position of the clutch pedal when the clutch is engaged is referred to as an engagement point. The oil adjusting mechanism 40 is connected into the oil pipe 30 between the primary end oil cylinder 10 and the terminal end oil cylinder 20, and specifically, the oil adjusting chamber 4011 in the oil cylinder 401 is used for absorbing oil bodies from the oil pipe 30, so that the purpose of adjusting the joint point position of the clutch is achieved.

More specifically, it is explained as: when the oil absorption of the oil adjusting chamber 4011 increases, the stroke of the final cylinder 20 is reduced relative to the stroke of the initial cylinder 10, and thus a position where the clutch pedal is depressed deeply becomes a joint point. Therefore, when the clutch pedal is returned from the limit position to engage the clutch, the required amount of return of the clutch pedal is reduced, and the clutch is engaged early. In contrast, when the oil absorbed by the oil adjusting chamber 4011 decreases, the stroke of the final end cylinder 20 increases relative to the stroke of the start end cylinder, and thus the position where the clutch pedal is depressed more shallowly becomes the engagement point. Therefore, when the clutch pedal is returned from the limit position to engage the clutch, the required amount of return of the clutch pedal increases, and the clutch is engaged with a delay.
