A wet clutch buffer control method and control system

Abstract

The invention relates to a wet clutch buffer control method and a control system. A control system including a computer, a frequency converter, a controller, a power transmission mechanism and an actuator is set; the control parameters of the frequency converter are set by the computer, and whether the control parameters are reasonable; Judging whether the input speed of the motor reaches the set value, if it reaches the set value, it is judged whether the speed difference between the input shaft and the output shaft of the clutch box is less than the preset upper limit value, and if it is less than the upper limit value, it enters the clutch box engagement process; after the engagement process ends Judging whether the speed difference is zero, after it is zero, enter the separation process of the clutch box; after the separation control process is completed, judge whether the operating oil pressure is close to zero, if it is close to zero, then adjust the speed of the motor through the controller and frequency converter ; The inverter controls the motor speed to be zero, power off, and the operation ends. The invention has the advantages of convenient operation, good cushioning effect and reliability, and can be widely applied in the field of wet clutch control.

Description

technical field [0001] The invention relates to a clutch control method and a control system, in particular to a wet clutch buffer control method and a control system in the field of wet clutch control. Background technique [0002] The wet clutch uses oil to soak the friction plate to accelerate heat dissipation and smooth and soft power transmission. Its advantages are stable operation, large transmission torque, long service life, and generally no failure. It is mostly used in automatic transmissions. The hydraulic cylinder presses multiple steel plates and friction plates to engage the clutch. After the oil is returned, the steel plates and friction plates are separated under the action of the spring force. Wet clutches are mainly used in vehicles, aerospace, air-cooled systems, oil drilling and other heavy machinery, especially in the automotive industry. In addition to AMT using single-plate dry clutches, AT, CVT, and DCT mostly use wet multi-plate clutches clutch. T...

AI Technical Summary

Problems solved by technology

When the existing wet clutch is engaged, the combination of relief valve and reversing valve will cause impact when the clutch friction plate is engaged, causing vibration of the transmission system; using the combination of secondary pressure control valve and reversing valve, the clutch The working oil pressure rise time has a great influence with the change of ambient temperature. When working with heavy load, the clutch will be seriously worn and aged; some methods of electro-hydraulic proportional control are not reliable, the judgment before control is not comprehensive enough, and the self-protection ability of the system is poor , the operation is more complicated

In addition, this buffer control method relies too much on hardware, the control form is too monotonous, and the buffer control effect is limited.
