變速箱漏油的原因，大部分都是由密封件（油封）老化造成的。
Most of the causes of transmission oil leakage are caused by the aging of seals (oil seals).
密封件（油封）時間長了會變硬，也就是說，隨著時間的推移他們失去增塑劑。這種過程因為持續的冷暖交替的工作溫度而加劇。這種糟糕過程的結果是密封件首先開始收縮，接著變硬，甚至斷裂，所以漏油變速箱是不可避免的出現。
Seals (oil seals) harden over time, that is, they lose plasticizer over time. This process is exacerbated by the continuous alternating working temperature of cold and warm. The result of this bad process is that the seal first shrinks, then hardens or even breaks, so the oil leakage gearbox is inevitable.
變速箱漏油的原因
Causes of transmission oil leakage
變速箱的工作條件比較苛刻，負荷變化較大。其結構設計十分緊湊，強化程度很高。實際工作時箱內溫度很高，使箱內潤滑油產生蒸氣，充滿箱體空間，導致箱內壓力升高。各密封截面都承受這個壓力的沖擊，往往在薄弱處油氣沖出而產生泄漏。就目前的情況來看，多數都是由于變速箱油溫過高、裝配工藝或變速箱油封質量這些問題所導致的漏油。
The working conditions of the gearbox are harsh and the load changes greatly. Its structural design is very compact and the degree of strengthening is very high. During actual operation, the temperature in the box is very high, which makes the lubricating oil in the box produce steam and fill the box space, resulting in the increase of pressure in the box. Each sealing section bears the impact of this pressure, and oil and gas often rush out at the weak point to produce leakage. As far as the current situation is concerned, most of the oil leakage is caused by the problems of high transmission oil temperature, assembly process or transmission oil seal quality.
變速箱漏油怎么看
What do you think of the transmission oil leakage
查看變速箱漏油很簡單，低頭往車底后部看,就可以看見變速箱底部是否漏油，如果漏油底部的油會沉積灰塵留下黑黑的一片油漬，如果是少量漏油可以查看變速箱箱體是否有油漬。
It's easy to check the oil leakage of the transmission. If you look down at the rear of the vehicle bottom, you can see whether there is oil leakage at the bottom of the transmission. If there is oil leakage, the oil at the bottom will deposit dust and leave a black oil stain. If there is a small amount of oil leakage, you can check whether there is oil stain on the transmission.
變速箱漏油怎么辦
What if the transmission leaks oil
如果變速箱出現漏油情況，一是要判斷是滲油還是漏油。有些滲油的發生并不是持續性的，只要不再嚴重就先不要理會。可以繼續的短途行駛，找到維修站查看變速箱漏油故障。
If there is oil leakage in the transmission, first, judge whether it is oil leakage or oil leakage. The occurrence of some oil seepage is not sustainable, so it should be ignored as long as it is no longer serious. You can continue to drive for a short distance and find the maintenance station to check the oil leakage fault of the transmission.
如果漏油變速箱很嚴重的話，要盡快檢查處理。當變速箱出現明顯的換擋沖擊和頓挫，就需要盡快檢查變速箱油，不然長期使用很有可能導致變速箱油溫過熱，變速箱齒輪間潤滑不良。同時，頻繁的高速運轉或急加速也會導致變速箱油溫升高，加大變速箱漏油的概率。具體的解決方法是清潔變速箱表面油漬，之后在漏油點部位打上密封膠。如有重大故障可能還需拆解變速箱箱體檢查維修。
If the oil leakage of the gearbox is very serious, check and deal with it as soon as possible. When there is obvious shift impact and setback in the transmission, it is necessary to check the transmission oil as soon as possible, otherwise long-term use may lead to overheating of the transmission oil temperature and poor lubrication between the transmission gears. At the same time, frequent high-speed operation or rapid acceleration will also lead to the increase of transmission oil temperature and increase the probability of transmission oil leakage. The specific solution is to clean the oil stain on the surface of the gearbox, and then apply sealant at the oil leakage point. In case of major faults, the gearbox may need to be disassembled for physical inspection and maintenance.
變速箱漏油的不良后果
Adverse consequences of transmission oil leakage
變速箱油和發動機油類似，主要起潤滑，清潔，降溫，防銹，密封。變速箱在運作時，會有高溫和高壓，如果變速箱油漏了，變速箱漏油會導致潤滑不足,齒輪間的摩擦磨損快，所以在解體變速箱時需要檢查有沒有發現齒輪磨損。
Transmission oil is similar to engine oil, mainly for lubrication, cleaning, cooling, rust prevention and sealing. When the gearbox is in operation, there will be high temperature and high pressure. If the gearbox oil leaks, the gearbox oil leakage will lead to insufficient lubrication and rapid friction and wear between gears. Therefore, it is necessary to check whether the gears are worn when disassembling the gearbox.
需要根據其磨損的情況更換換擋齒輪。漏油一定要修理，變速箱里面都是齒輪，只要車走齒輪就在工作，齒輪需要齒輪油的潤滑，當齒輪油漏完以后齒輪干摩擦，長時間務潤滑的情況下行使以后變速箱也就基本上報廢了。
The shift gear needs to be replaced according to its wear. Oil leakage must be repaired. There are gears in the gearbox. As long as the car goes, the gears are working. The gears need gear oil lubrication. When the gear oil leaks, the gears dry friction. After running for a long time, the gearbox will basically be scrapped.
