变速箱漏油的原因，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）时间长了会变硬，也就是说，随着时间的推移他们失去增塑剂。这种过程因为持续的冷暖交替的工作温度而加剧。这种糟糕过程的结果是密封件首先开始收缩，接着变硬，甚至断裂，所以漏油变速箱是不可避免的出现。
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.
变速箱漏油的原因
Causes of transmission oil leakage
变速箱的工作条件比较苛刻，负荷变化较大。其结构设计十分紧凑，强化程度很高。实际工作时箱内温度很高，使箱内润滑油产生蒸气，充满箱体空间，导致箱内压力升高。各密封截面都承受这个压力的冲击，往往在薄弱处油气冲出而产生泄漏。就目前的情况来看，多数都是由于变速箱油温过高、装配工艺或变速箱油封质量这些问题所导致的漏油。
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.
变速箱漏油怎么看
What do you think of the transmission oil leakage
查看变速箱漏油很简单，低头往车底后部看,就可以看见变速箱底部是否漏油，如果漏油底部的油会沉积灰尘留下黑黑的一片油渍，如果是少量漏油可以查看变速箱箱体是否有油渍。
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.
变速箱漏油怎么办
What if the transmission leaks oil
如果变速箱出现漏油情况，一是要判断是渗油还是漏油。有些渗油的发生并不是持续性的，只要不再严重就先不要理会。可以继续的短途行驶，找到维修站查看变速箱漏油故障。
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.
如果漏油变速箱很严重的话，要尽快检查处理。当变速箱出现明显的换挡冲击和顿挫，就需要尽快检查变速箱油，不然长期使用很有可能导致变速箱油温过热，变速箱齿轮间润滑不良。同时，频繁的高速运转或急加速也会导致变速箱油温升高，加大变速箱漏油的概率。具体的解决方法是清洁变速箱表面油渍，之后在漏油点部位打上密封胶。如有重大故障可能还需拆解变速箱箱体检查维修。
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.
变速箱漏油的不良后果
Adverse consequences of transmission oil leakage
变速箱油和发动机油类似，主要起润滑，清洁，降温，防锈，密封。变速箱在运作时，会有高温和高压，如果变速箱油漏了，变速箱漏油会导致润滑不足,齿轮间的摩擦磨损快，所以在解体变速箱时需要检查有没有发现齿轮磨损。
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.
需要根据其磨损的情况更换换挡齿轮。漏油一定要修理，变速箱里面都是齿轮，只要车走齿轮就在工作，齿轮需要齿轮油的润滑，当齿轮油漏完以后齿轮干摩擦，长时间务润滑的情况下行使以后变速箱也就基本上报废了。
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.
