The role of the automobile clutch master pump
The main function of the automobile clutch master pump is to convert the force generated by the clutch pedal into hydraulic pressure and transfer it to the clutch sub-pump through the tubing, so as to realize the separation and engagement of the clutch. Specifically, when the driver presses down on the clutch pedal, the push rod will push the master pump piston, so that the oil pressure will increase, through the hose into the sub-pump, forcing the sub-pump pull rod to push the separation fork, the separation bearing forward, so that the clutch to achieve separation. When the clutch pedal is released, the hydraulic pressure is released, the separation fork gradually returns to the original position under the action of the return spring, and the clutch is in the engaged state .
In addition, the clutch master pump is also connected with the clutch booster through the tubing, which can collect the travel information of the clutch pedal of the owner to ensure the flexible and stable operation of the clutch . The damage of the clutch master pump will lead to the difficulty of gear hanging and shifting, and it is impossible to accelerate, so it needs timely maintenance and replacement .
Collect pedal travel information and disengage the clutch through the booster . The clutch master pump is connected to the clutch pedal to collect the driver's pedal travel information. When the driver presses the clutch pedal, the push rod pushes the piston of the master pump to increase the oil pressure, and the hydraulic pressure is transferred to the clutch sub-pump through the hose, forcing the disengaging fork to push the disengaging bearing to achieve clutch disengagement .
Ensure a smooth start and smooth shift . By controlling hydraulic pressure, the clutch master pump enables the clutch to engage smoothly when starting, avoiding the impact of sudden engagement between the engine and the transmission. During the shift process, the clutch master pump can temporarily cut off the connection between the engine and the transmission, making the shift more smooth and reducing the impact of the shift .
Protect the transmission system . In the case of emergency braking or transmission overload, the clutch master pump can quickly cut off the contact between the engine and the transmission, prevent the transmission system from being damaged due to overload, thus protecting the vehicle's transmission system .
Fault symptoms and maintenance . After the clutch master pump is damaged, there will be difficulties in gear hanging and shifting, and the vehicle cannot accelerate. Timely maintenance and replacement of parts are required to ensure the normal operation of the clutch .
The solution to the broken car clutch master pump mainly includes the following:
Replace clutch master pump : If the clutch master pump is damaged, it is usually necessary to replace it with a new master pump. Since the clutch master pump is damaged and cannot be repaired, the problem can only be solved by replacing the new master pump .
Inspect and replace damaged parts : If the clutch master pump damage is due to internal rubber ring damage, lack of clutch oil, clutch disc wear serious reasons, need to inspect and replace these damaged parts. For example, replace the internal rubber ring, add clutch oil or replace the clutch disc .
improve driving habits : Improper operation of the driver is one of the common causes of damage to the clutch master pump. Therefore, improving driving habits, avoiding frequent stepping on clutch, long-term stepping on clutch and other operations, can effectively extend the service life of the clutch master pump .
Signs of clutch master pump failure include:
Oil leakage : When the clutch master pump is damaged, there will be oil leakage .
gear hanging difficulty : when shifting, it will obviously feel difficult to hang up the corresponding gear, or even unable to hang up any gear .
clutch pedal paresthesia : When stepping on the clutch, you will feel that the clutch pedal is very empty and lacks the due resistance, which usually means that the clutch master pump cannot provide sufficient pressure .
