What is clutch tubing
Automobile clutch oil pipe is an important part of automobile clutch hydraulic system, its main function is to transfer oil pressure to control the working state of the clutch. The clutch tubing converts pedal operation into hydraulic energy via a hydraulic system, thereby controlling clutch disengagement and coupling .
The specific working principle of the clutch tubing is as follows: when the driver presses the clutch pedal, the hydraulic oil is transferred from the main pump to the sub-pump under the action of pressure, and the sub-pump starts to work. The piston movement of the branch pump further pushes the ejector rod, so that the disengaging fork separates the clutch pressure plate and friction plate from the flywheel, achieving the clutch separation state for shifting operation .
The causes of oil leakage in the clutch tubing may include the following:
Poor quality, material or technology of parts.
In summer, the engine temperature is too high, and the oil seal and rubber pad are easy to age, resulting in reduced sealing.
The fastening screw is affected by thermal expansion and cold contraction, and the fastening force is not uniform.
External impact causes internal engine parts to deform .
If there is oil leakage in the clutch tubing, it is recommended to immediately go to the 4S shop for after-sales repair, so as not to cause greater losses .
The main reasons for the explosion of automobile clutch tubing include the following :
Tubing quality problem : the quality of the tubing itself is not up to standard, there may be design defects or manufacturing problems, resulting in the tubing unable to withstand normal oil pressure and burst .
tubing aging : after a long time of use, the tubing material will age, the sealing performance will decline, can not withstand normal oil pressure, resulting in burst .
oil pipe connection screws loose : the screws at the oil pipe connection are not fastened or loose, resulting in unstable internal oil pressure, which may cause oil pipe burst .
Improper installation : Inaccurate installation or improper installation of the tubing may cause the tubing to bear additional pressure during use and thus burst .
Return pipe plugging : return pipe plugging will lead to increased oil pressure, increase the load on the tubing, and may eventually lead to tubing bursting .
aging of sealing material : sealing material will wear, aging and deterioration after long-term use, resulting in reduced sealing performance and tubing burst .
Extreme temperature variations : tubing shrinks and becomes brittle in cold climates and expands under extra pressure at high temperatures, which can cause tubing to burst under extreme conditions .
Mechanical injury : daily driving may be hit by sharp objects on the road, stones or other vehicles caused mechanical damage, resulting in oil pipe burst .
Prevention and solutions :
Regular inspection and maintenance : regularly check the status of the tubing, timely replacement of aging tubing and seals.
Fastening connection screws : Ensure that all connection screws are firmly tightened to avoid oil pipe burst due to screw loosening.
correct installation : Ensure that the installation position of the tubing is accurate to avoid the explosion caused by improper installation.
Avoid extreme temperature changes : Use protective measures at extreme temperatures to reduce thermal expansion and contraction of tubing.
