The clutch release system with hydraulic release bearing has become the most mainstream form of the clutch release system at present because of its lightweight, high integration and high work efficiency. The hydraulic release bearing is also known as the coaxial hydraulic auxiliary cylinder; as the name implies, the coaxial hydraulic auxiliary cylinder still plays the role of the slave cylinder in the clutch release system. However, compared with the traditional hydraulic auxiliary cylinder, the difference is that it integrates a release bearing with a guide sleeve, and the hydraulic cylinder pushes the release bearing to complete the separation of the clutch, abandoning the traditional structure of the fork + release bearing, and the degree of integration is high.
1. The hydraulic release bearing cannot be pressed or pressurized without being fixed, otherwise the hydraulic cylinder will be damaged.
2. Check whether the new hydraulic release bearing is complete, and whether the oil seal or sealing ring of the gearbox has oil leakage. If so, it needs to be replaced in time.
3. The hydraulic system can be exhausted only after the gearbox and engine are installed.
There are three situations in which the clutch hydraulic release bearing is frequently damaged. One is poor driving habits, that is, after shifting gears, the left foot does not leave the clutch pedal, causing the clutch release bearing to work for a long time, so it will be damaged. The second is poor installation. After installation, the free stroke of the clutch pedal is not adjusted properly, causing the release bearing to keep rotating, so it will also be damaged in a short time. The third is that the quality of the car clutch bearing is really bad, and it will not take long for it's broken. It is estimated that the second possibility is relatively high, so after the replacement, check the free travel of the clutch pedal, and then look at the free movement of the separation fork.
Depress the clutch pedal to the semi-linked position, and a sound will be heard at this time to determine that the release bearing is damaged. The clutch hydraulic release bearing is a relatively important part of the car. If the maintenance is not good and the failure occurs, it will not only cause economic losses, but also it is very troublesome to disassemble and assemble once, and it takes a lot of man-hours. Therefore, to find out the reasons for the failure of the clutch release bearing, and to maintain and maintain it reasonably in use, is of great significance to prolong the life of the release bearing, improve labor productivity, and achieve better economic benefits.
The clutch release bearing (i.e. opel corsa release bearing) is installed between the clutch and the transmission, and the release bearing seat is loosely sleeved on the tubular extension of the first shaft bearing cover of the transmission. The shoulder of the release bearing is always pressed against the release fork by the return spring, and returns to the final position , and keep a gap of about 3~4mm with the end of the separation lever (separation finger).
