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.

　　如果自動變速箱漏油不及時處理，不僅會在傳動過程中損壞傳動部件，還會縮短傳動的使用壽命。對于變速器漏油的維修，在還不知道哪一部分漏油的情況下，不能盲目的去處理。找到漏油的原因將會解決這個問題。三和自動擋變速維修專注于自動變速箱維修多年，總結出自動變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、頸部油封漏油原因:油封老化變形,油封彈簧脫落或油封錯誤的方向,將使油封失去石油的作用,應該更換油封老化變形,注意安裝方向的油封,油封的彈簧環的一面應該朝與石油。軸頸偏心磨損或凹陷，與油封配合不當造成漏油，應更換或修復。

　　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、箱體連接處漏油原因:如果箱體連接處有破損，則在破損處加厚墊紙。2. 如果密封墊損壞，應更換相同的密封墊。3.如果箱蓋螺絲松動，應及時擰緊。

　　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、軸承前關節面漏油原因:如果密封墊損壞，應及時更換同一密封墊。二、擰緊時螺絲是否松動，應按對角線順序擰緊，但不宜過緊，以免損壞紙墊。此外，變速箱的通氣孔被堵塞，變速箱工作時與外界空氣隔絕，導致箱內壓力增大，也使機油從插頭處泄漏。齒輪箱的通氣孔應保持打開，以降低箱內壓力，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、油封或法蘭磨損，齒輪油超過規定的標準。

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

　　5、每軸端間隙過大，閥座孔、軸承松動，墊片損壞失效，密封墊片損壞或丟失。

　　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、各密封件表面加工質量不符合產品圖紙要求，油封老化失效，螺栓緊固松動。

　　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、不當使用潤滑油,如:18蒸餾的后橋雙曲線齒輪油到傳輸(即和齒輪油混合)的傳播,這樣的盒子潤滑油產生很多泡沫,導致液面上升(泡沫)。油泡通過傳動軸軸承蓋內壁泄漏進入離合器殼體底蓋，嚴重的還會使摩擦盤與油接觸。

　　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.
