The clutch release bearing includes a clutch release bearing, a clutch release bearing seat, a hydraulic release bearing and a release bearing guide bush. Through the release bearing, the release rod can move axially along the clutch output shaft while rotating, so as to ensure the smooth engagement and soft separation of the clutch, reduce wear and prolong the service life of the clutch and the entire transmission system.
The swift clutch bearing is a thrust bearing (commonly known as the clutch ball disc). Its function is to move the pressure plate or active plate under the spring thrust to the clutch housing when the clutch pedal is depressed, that is to say, when the clutch pedal is depressed, the release lever is inclined to overcome the spring thrust of the pressure plate and complete the clutch release. The release lever of the clutch rotates with the pressure plate, but the operating mechanism linked with the clutch pedal cannot rotate. To accommodate the different motion states between the two, thrust bearings are used to reduce friction and wear. If the clutch release bearing loses its sliding action due to lack of oil, it will not only produce abnormal noise, but also aggravate the loss of the force point of the release lever, and the effective range of the clutch pedal to start the pressure plate will become smaller and smaller. When the clutch plate and the pressure plate are not completely separated, the gear shift will produce abnormal noise, and the wear of the separation lever will cause the pressure plate to start unevenly or incompletely.
The clutch release bearing seat fits loosely over the tubular extension of the first shaft bearing cap of the transmission, the shoulder of the release bearing always rests against the release fork by the return spring and returns to its final position, remaining approximately 2.5 mm from the release lever Clearance.
Since the clutch pressure plate, the release lever and the engine crankshaft operate synchronously, the release fork can only move axially along the clutch output shaft, and it is obviously impossible to directly shift the release lever with the release fork. Through the clutch release bearing, the release lever can move axially along the clutch output shaft while rotating, thereby ensuring smooth engagement and soft disengagement of the clutch, reducing wear and prolonging the service life of the clutch and the entire transmission system.
