Something You Should Know about Clutch Bearing

The clutch release bearing is a relatively important part of the automobile. It is installed between the clutch and the transmission. The release bearing seat is loosely sleeved on the tubular extension of the first shaft bearing cover of the transmission. The return spring makes the shoulder of the release bearing always Hold the release fork, and retreat to the final position, keeping a gap of about 3~4mm with the end of the release lever (separation finger).

How does the clutch release bearing work?

A clutch release bearing is mounted between the clutch and the transmission, and the release bearing seat is loosely fitted over the tubular extension of the transmission's first shaft bearing cap. With the return spring, the shoulder of the release bearing always rests on the release fork and retreats to its final position with a clearance of about 3 to 4 mm from the end of the release lever (release finger).

The clutch release bearing runs synchronously with the clutch pressure plate, release lever and engine crankshaft, but the release fork can only move axially along the clutch output shaft. Obviously, it is impossible to directly shift the release lever with the release fork. By using a release bearing, the release lever can move axially along the clutch output shaft while rotating, thereby ensuring smooth engagement of the clutch, gentle disengagement, reduced wear, and extended service life of the clutch and the entire transmission system.

What is the function of the clutch release bearing?

The clutch release bearing is a kind of thrust bearing (commonly known as the clutch pin), its function is to move the pressure plate or drive plate that bears the spring thrust to the direction of the clutch cover when the clutch pedal is depressed, that is to say, when the clutch pedal is depressed Tilt the release lever to overcome the thrust of the pressure plate spring to complete the clutch release.

The release lever of the clutch rotates with the pressure plate, while the operating mechanism linked with the clutch pedal cannot rotate. In order to adapt to the different motion conditions between the two, a thrust bearing is used to reduce friction and wear. If the release bearing loses its sliding function due to lack of oil, it will not only produce abnormal noise, but also aggravate and damage 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 disengaged, the shifting will produce abnormal noise, and the wear of the separation lever will cause the pressure plate to start unevenly or incompletely, and the drive and the driven are interrelated, and finally the gear cannot be changed.

Precautions for use:

• According to the operating procedures, avoid the clutch half-engagement and half-separation, and reduce the number of times the clutch is used.

• Pay attention to maintenance, soak butter by cooking method regularly or during annual inspection and maintenance, so that it has sufficient lubricant.

• Pay attention to leveling the clutch release lever to ensure that the elasticity of the return spring meets the requirements.

• Adjust the free stroke to meet the requirements (30-40mm) and prevent the free stroke from being too large or too small.

• Minimize the number of joints and separations to reduce shock loads.

• It is easy to step on, so it can be engaged and disengaged smoothly.
