The clutch kit is between the engine and the transmission, clutch slip is a common problem when driving not only the way of using clutch pedal and its technical performance directly affects the transmission of the engine power, and the transmission gear control,which requires the clutch to achieve the combination of translation reliable, complete separation, transmission sound.Due to the frequent use of the clutch, wear or damage is inevitable, technical performance is easy to deteriorate or failure. Release bearing breaking analysis
1.The phenomenon of clutch slip When the car starts
The clutch pedal is fully raised, which makes it difficult to start.In the process of driving, the speed of the vehicle can not be quickly increased with the acceleration of the engine speed, the vehicle power is insufficient, and there is a coke smell produced by the clutch friction plate, this phenomenon is suspected to be clutch slip.
Fault judgment: using the gear starting method and rocker method.
Gear starting method:
Tighten the hand brake, hang into low gear, slowly lift the clutch pedal, gently refueling.If the car is not moving, the engine is not stalled, diagnosed as clutch slip.
Machine-cleaned pulled method:
Hang into the low gear, tighten the hand brake, and forward the engine crankshaft by hand.If the clutch can be turned, it can also be diagnosed as slipping.
clutch slip Solutions:
STEP1:
Check whether the clutch pedal has free travel.
The way to do it is to step on the pedal and judge by feeling.It is more intuitive to remove the lower cover of the clutch and see whether there is a gap between the separation lever and the separation bearing.No clearance, no free stroke, should be adjusted.
STEP2:
If the free travel of the pedal meets the requirements, the inspection can be done from under the car to check whether the friction edge of the clutch disc is clean or not.If there is oil thrown out, there is oil on the friction plate caused by skid.If there are scorch marks and hot car when there was burnt smell, smoke phenomenon, is the clutch friction plate ablation slip.
One person in the driving position to step on the clutch pedal, another person under the car with a driver to push the driven disc friction plate, if in the falling object found aluminum powder, is the clutch friction plate rivets exposed and slip.The slip fault listed in the second item can only be removed by removing the clutch from the car.The surface oil of the friction plate can be cleaned with gasoline and then dried with compressed air.The oil on the surface of the friction plate can be repaired with a scraper or polished with sandpaper to remove the hardening layer.If the ablation is severe or the friction rivets are exposed, the friction plates should be replaced.
STEP3:
If the above test is good, the reason for the slip is caused by the decline of the elastic force of the compressed spring, and the friction plate needs to be replaced.
Gear starting method:
Tighten the hand brake, hang into low gear, slowly lift the clutch pedal, gently refueling.If the car is not moving, the engine is not stalled, diagnosed as clutch slip.
Machine-cleaned pulled method:
Hang into the low gear, tighten the hand brake, and forward the engine crankshaft by hand.If the clutch can be turned, it can also be diagnosed as slipping.
