What is the oil pan of the automobile transmission
automotive transmission oil pan is an important part of the gearbox, its main function is to store the lubricating oil in the gearbox and help dissipate the heat generated when the gearbox is working. The oil pan is usually located at the very bottom of the gearbox and is made of a strong metal material to ensure that it can handle the pressure and weight inside the gearbox .
Structure and function
The transmission oil pan usually contains a magnet to absorb metal debris generated by operation. When replacing transmission oil, remove the oil pan to clean debris, check whether the oil pan is bumped, damaged, or deformed, replace the sealing element and filter element, and reinstall the .
Care and maintenance
Changing the transmission oil regularly is the key to keeping the transmission working properly. When replacing transmission oil, the oil pan needs to be removed for cleaning and inspection to ensure that there are no metal debris or other impurities inside. In addition, it is necessary to check whether the oil pan is damaged or deformed, and replace the original seal and filter element before re-installing .
The main functions of the automotive transmission oil pan include storing and sealing transmission oil, cooling transmission oil and preventing oil leakage.
Store and seal transmission fluid : The main function of the transmission oil pan is to store transmission fluid and ensure that it does not leak. The transmission oil sump is tightly connected with the gearbox through the gasket to prevent transmission oil leakage .
Cooling transmission oil : The transmission oil pan also plays a role in cooling transmission oil, helping to maintain the normal working temperature of the transmission and preventing the oil temperature from being too high .
Prevent oil leakage : If there is oil leakage in the transmission oil pan, it is usually only necessary to replace the oil pan gasket to solve the problem. Due to the high working temperature of the transmission oil pan of high-performance cars, the gasket is easy to age, so it is more prone to oil leakage .
Protect internal components : As a part of the gearbox, the transmission oil pan plays the role of protecting the internal transmission components, and fixing and supporting the internal structure of the gearbox .
The fault of oil pan of automobile transmission is mainly manifested as oil seepage or oil leakage, the main reasons include aging of gasket, loosening or damage of screws, aging of tubing and so on. The specific fault causes and solutions are as follows:
Aging or damaged gasket : Aging or damaged gasket of transmission oil pan may result in oil seepage. The solution is to remove the gearbox oil pan, replace the gasket or apply glue at the local oil leakage spots .
Loose or damaged screws : the oil bottom screws are not tightly sealed or the screw holes are deformed, which may lead to oil seepage. The solution is to check and tighten the screws and replace the damaged screws or oil pan if necessary.
aging tubing : aging deformation of transmission cooling tubing connection will lead to leakage. The solution is to replace the new cooling tubing .
gearbox rear housing leakage : need to remove gearbox rear housing, replace gasket and reinstall .
input shaft oil seal aging : need to remove the gearbox, replace the new oil seal .
Preventive measures and maintenance suggestions
regular check : regularly check the seal of the oil pan of the gearbox, and deal with the problem of oil seepage in time.
Replace the standard oil : use the oil that meets the standard of the original car to avoid the oil leakage caused by the oil does not meet the standard .
avoid collision : pay attention to avoid collision between chassis and obstacles when driving, reduce the risk of oil pan damage .
correct maintenance : replace and check transmission oil according to the manufacturer's recommended time and mileage to ensure that the oil level is within the normal range .
