由于国内道路交通拥堵，造成车辆不能升入高档，频繁在低速档切换，造成磨损产生杂质，容易堵塞油道，加速变速箱损坏，只有及时更换变速箱油才能保证正常使用寿命。那么在换变
济南变速箱油时，我们需要注意什么？
Due to traffic congestion on domestic roads, vehicles are unable to move into high gear and frequently switch between low gears, resulting in wear and impurities, easy blockage of oil passages, and damage to the acceleration gearbox. Only by replacing the gearbox oil in a timely manner can normal service life be guaranteed. So what should we pay attention to when changing Jinan transmission oil?
1、变速箱和后桥分开选
1. Separate selection of gearbox and rear axle
由于变速箱和后桥齿轮的材质和结构不同，要分开选油，以保证变速箱密封件不泄露，铜部件不腐蚀及后桥齿轮得到充分的润滑。
Due to the different materials and structures of the gearbox and rear axle gears, separate oil selection is necessary to ensure that the gearbox seals do not leak, copper components do not corrode, and the rear axle gears receive sufficient lubrication.
2、选择粘度
2. Select viscosity
如果粘度选择过大，会使摩擦面过热，也会造成不必要的动力损耗，如果粘度选择过小，由于离心力的作用将油从齿面甩掉，容易造成油封漏油，可能在齿轮面上形成贫油润滑，从而磨损加大，甚至会产生烧结现象，因此选择适合的粘度非常重要。
If the viscosity is chosen too high, it will cause overheating of the friction surface and unnecessary power loss. If the viscosity is chosen too low, the oil will be thrown away from the tooth surface due to the centrifugal force, which is easy to cause oil seal leakage and may form lean oil lubrication on the gear surface, leading to increased wear and even sintering. Therefore, choosing a suitable viscosity is very important.
3、车辆变速箱油的分级和正确使用
3. Classification and correct use of vehicle transmission oil
车辆齿轮油即车辆变速器、驱动桥等齿轮传动机构所用的润滑油被视为齿轮装置的重要结构材料，其粘度和承载能力成为设计的重要依据之一。因此齿轮油在使用中必须严格按规定要求选用，否则会降低齿轮装置的使用寿命，甚至造成早期损坏。
Vehicle gear oil, that is, lubricating oil used for gear transmission mechanisms such as vehicle transmission and drive axle, is regarded as an important structural material of gear device, and its viscosity and load capacity become one of the important basis for design. Therefore, gear oil must be selected in strict accordance with the specified requirements in use, otherwise it will reduce the service life of the gear unit, or even cause early damage.
4、选用高质量的品牌车辆变速箱油
4. Choose high-quality branded vehicle transmission oil
高质量的品牌车辆变速箱油不仅可以有效保护齿轮，降低磨损，使车辆运行更轻松，节约燃油，同时可以延长油品使用寿命，降低保养及维修费用。因此在选择车辆变速箱油时，要到销售渠道正规的地点购买高质量的品牌车辆变速箱油，保护好您的爱车。
High quality branded vehicle transmission oil can not only effectively protect gears, reduce wear, make vehicle operation easier, save fuel, but also extend the service life of the oil and reduce maintenance and repair costs. Therefore, when choosing vehicle transmission oil, it is important to purchase high-quality branded vehicle transmission oil from reputable sales channels to protect your car.
