自动变速器的维修标准

Maintenance standards for automatic transmissions

一般自动变速器(ATF)的润滑油需要两年换一次,自动变速器每4万需要清洗保养。

The lubricating oil of a typical automatic transmission (ATF) needs to be changed every two years, and automatic transmissions require cleaning and maintenance every 40000 kilometers.

以上的自动变速器故障都是由自动变速器润滑油过热和杂质引起的。对于自动变速器的保养,合理更换自动变速器润滑油是关键。如果自动变速器润滑油变质,会降低变速器内部零件的耐磨性,缩短自动变速器的使用寿命。另外,自动变速器中的油泥和杂质会直接影响系统的油压和动力传递,使自动变速器的速度变慢,甚使某个挡位失效。

The above automatic transmission faults are all caused by overheating and impurities in the lubricating oil of the automatic transmission. Reasonable replacement of automatic transmission lubricating oil is crucial for the maintenance of automatic transmissions. If the lubricating oil of the automatic transmission deteriorates, it will reduce the wear resistance of internal parts of the transmission and shorten the service life of the automatic transmission. In addition, the sludge and impurities in the automatic transmission can directly affect the oil pressure and power transmission of the system, causing the speed of the automatic transmission to slow down and even causing a certain gear to fail.

如果用于正常保养,自动变速器的平均寿命在70万左右。

If used for normal maintenance, the average lifespan of an automatic transmission is around 700000 kilometers.

自动变速器的维护方法

Maintenance methods for automatic transmissions

经常检查自动变速器的油位是否正常。自动变速器油的检查方法不同于发动机油。机油要在冷态下检查,而变速器油需要预热到50左右,在每个档位停留2s后再将变速杆放入驻车档。此时,油尺的正常油位应该在高线和低线之间。如果不够,及时添加同质量的机油。

Regularly check if the oil level of the automatic transmission is normal. The inspection method for automatic transmission oil is different from engine oil. The oil needs to be checked in a cold state, and the transmission oil needs to be preheated to around 50. After staying in each gear for 2 seconds, put the gear lever into park. At this point, the normal oil level on the dipstick should be between the high and low lines. If not enough, add oil of the same quality in a timely manner.

掌握自动变速器的换油周期。自动变速器的内部控制机构非常精密,配合间隙小,所以大部分厂家建议自动变速器的换油周期通常为两年或4 ~ 6万。在正常使用中,变速器油的工作温度一般在120左右,所以油的品质要求很高,必须保持清洁。其次,变速器油使用时间长了会产生油垢,油垢可能会形成油泥,增加摩擦片和部件的磨损,也会影响系统的油压,从而影响动力传递。再次,污油中的油泥会使各阀体内的阀体运动不顺畅,油压控制受到影响,从而使自动变速器不正常。

Master the oil change cycle of automatic transmissions. The internal control mechanism of automatic transmissions is very precise and has small clearance, so most manufacturers recommend that the oil change cycle of automatic transmissions is usually two years or 40000 to 60000 kilometers. In normal use, the working temperature of transmission oil is generally around 120, so the quality of the oil is required to be high and must be kept clean. Secondly, prolonged use of transmission oil can generate oil deposits, which may form sludge, increase wear on friction plates and components, and also affect the oil pressure of the system, thereby affecting power transmission. Once again, the sludge in the dirty oil can cause the valve bodies inside each valve body to move unsmooth, affecting oil pressure control and causing the automatic transmission to malfunction.

正确更换变速器油。目前比较好的换油方式是动态换油,使用专门的齿轮箱清洗设备。变速箱运行过程中,旧油充分循环,待完全排出后再加入新的变速箱油。换油率可达90%以上,换油效果好。平时要培养主动检查保养的意识,学习一些汽车保养的基本知识,仔细阅读车上的说明书,记住一些必要的数据。科学的汽车保养可以保证车辆处于良好的技术状态和行驶。

Replace the transmission oil correctly. The current better oil change method is dynamic oil change, using specialized gearbox cleaning equipment. During the operation of the gearbox, the old oil is fully circulated, and new gearbox oil is added after it is completely discharged. The oil change rate can reach over 90%, and the oil change effect is good. We should cultivate the awareness of proactive inspection and maintenance in daily life, learn some basic knowledge of car maintenance, carefully read the instructions on the car, and remember some necessary data. Scientific car maintenance can ensure that vehicles are in good technical condition and driving safety.
