At present, many cars are automatic transmission cars. We all know that automatic transmission cars are easy to operate. The application of automatic gearbox in automatic vehicle is of great significance to the research of automatic gearbox. If the automatic transmission fails, it will affect the use of the automatic vehicle, and will cause the automatic vehicle can not operate normally. The failure of automatic transmission is caused by various factors of automobile, such as the leakage of oil in automatic transmission, which is the cause of fuse failure.

　　如果自动变速箱漏油不及时处理，不仅会在传动过程中损坏传动部件，还会缩短传动的使用寿命。对于变速器漏油的维修，在还不知道哪一部分漏油的情况下，不能盲目的去处理。找到漏油的原因将会这个问题。三和自动挡变速维修专注于自动变速箱维修多年，总结出自动变速箱漏油的原因如下:

　　If the oil leakage of the automatic transmission is not handled in time, it will not only damage the transmission parts in the transmission process, but also shorten the service life of the transmission. For the maintenance of transmission oil leakage, we can't deal with it blindly without knowing which part of the oil leakage is. Finding the cause of the leak will solve the problem. Third, automatic transmission maintenance has been focused on automatic transmission maintenance for many years, and summarized the causes of automatic transmission oil leakage as follows:

　　1、颈部油封漏油原因:油封老化变形,油封弹簧脱落或油封错误的方向,将使油封失去石油的作用,应该更换油封老化变形,注意安装方向的油封,油封的弹簧环的一面应该朝与石油。轴颈偏心磨损或凹陷，与油封配合不当造成漏油，应更换或修复。

　　1. Causes of neck oil seal leakage: the aging and deformation of the oil seal, the falling off of the oil seal spring or the wrong direction of the oil seal will make the oil seal lose the role of oil. The aging and deformation of the oil seal should be replaced. Pay attention to the oil seal in the installation direction, and one side of the spring ring of the oil seal should face the oil. If the journal is eccentrically worn or dented, and the oil leakage is caused by improper matching with the oil seal, it shall be replaced or repaired.

　　2、箱体连接处漏油原因:如果箱体连接处有破损，则在破损处加厚垫纸。2. 如果密封垫损坏，应更换相同的密封垫。3.如果箱盖螺丝松动，应及时拧紧。

　　2. Cause of oil leakage at the box connection: if the box connection is damaged, thicken the pad paper at the damaged place. 2. If the gasket is damaged, replace the same gasket. 3. If the box cover screws are loose, they should be tightened in time.

　　3、轴承前关节面漏油原因:如果密封垫损坏，应及时更换同一密封垫。二、拧紧时螺丝是否松动，应按对角线顺序拧紧，但不宜过紧，以免损坏纸垫。此外，变速箱的通气孔被堵塞，变速箱工作时与外界空气隔绝，导致箱内压力增大，也使机油从插头处泄漏。齿轮箱的通气孔应保持打开，以降低箱内压力，防止漏油。

　　3. Cause of oil leakage on front joint surface of bearing: if the gasket is damaged, replace the same gasket in time. 2、 If the screw is loose during tightening, it should be tightened in diagonal order, but it should not be too tight to avoid damaging the paper pad. In addition, the vent hole of the gearbox is blocked, and the gearbox is isolated from the outside air when working, which causes the pressure in the gearbox to increase, and also causes the oil to leak from the plug. The vent hole of the gearbox shall be kept open to reduce the pressure in the gearbox and prevent oil leakage.

　　4、油封或法兰磨损，齿轮油超过规定的标准。

　　4. The oil seal or flange is worn, and the gear oil exceeds the specified standard.

　　5、每轴端间隙过大，阀座孔、轴承松动，垫片损坏失效，密封垫片损坏或丢失。

　　5. The clearance at each shaft end is too large, the valve seat hole and bearing are loose, the gasket is damaged and invalid, and the sealing gasket is damaged or lost.

　　6、各密封件表面加工质量不符合产品图纸要求，油封老化失效，螺栓紧固松动。

　　6. The surface processing quality of each seal does not meet the requirements of the product drawing, the oil seal is aging and invalid, and the bolt is loose.

　　7、不当使用润滑油,如:18蒸馏的后桥双曲线齿轮油到传输(即和齿轮油混合)的传播,这样的盒子润滑油产生很多泡沫,导致液面上升(泡沫)。油泡通过传动轴轴承盖内壁泄漏进入离合器壳体底盖，严重的还会使摩擦盘与油接触。

　　7, improper use of lubricating oil, such as: 18 distillation of the rear axle hyperbolic gear oil to transmission (that is, mixing with gear oil), such a box of lubricating oil produces a lot of foam, resulting in the rise of liquid level (foam). The oil bubble leaks into the bottom cover of clutch housing through the inner wall of the bearing cover of the first transmission shaft, and seriously contacts the friction plate with oil.
