自动变速器,亦称自动变速箱,台湾称为自排变速箱,香港称为自动波,通常来说是一种可以在车辆行驶过程中自动改变齿轮传动比的汽车变速器,从而使驾驶员不必手动换档,也用于大型设备铁路机车。

Automatic transmission, also known as automatic transmission, Taiwan is called self-propelled transmission, Hong Kong is called automatic wave. Usually, it is a kind of automobile transmission that can automatically change the gear ratio in the course of driving, so that drivers do not have to shift gears manually. It is also used in large equipment railway locomotives.

很多汽车发烧友们都喜欢自己学点汽车维修保养方面的知识,有个小毛病就自己动手解决了,换个胎、换个机油、机滤什么的都不在话下,但是对一些新型的东西了解就不一定足够了。比如现在越来越普遍的自动变速器,在更换它的传动液时就不能用原来简单的方法了。

Many automobile enthusiasts like to learn some knowledge about automobile maintenance and repair by themselves. They solve a minor problem by themselves. They can change tires, oil and filter everything, but they don't necessarily know enough about some new things. For example, now more and more popular automatic transmission, in the replacement of its transmission fluid can not be used in the original simple method.

在大多数司机眼中,更换自动变速箱中的传动液(即atf液)和更换发动机机油是一样的,只要找个地方把旧油一放,拧紧放油塞,把新油倒入,查查油尺就完事大吉了,其实不然。

In the eyes of most drivers, changing the transmission fluid (atf fluid) in the automatic transmission is the same as changing the engine oil. As long as you find a place to put the old oil, tighten the plug, pour the new oil into it and check the fuel ruler, you will be all right.

现代汽车自动变速器是高度精密的动力传输装置,多是由电脑来控制,装备有许多精密部件:液力变扭器、太阳轮、行星轮和复杂而细小的油道等,它们对其中的污染物和温度变化非常敏感。如果缺少必要的保养,自动变速器会出现工作粗暴、换档困难等故障。据统计,90%的自动变速器故障是由于传动液污染劣化引起的。

Modern automotive automatic transmission is a highly precise power transmission device, which is controlled by computer. It is equipped with many precise components: hydraulic torque converter, solar wheel, planetary wheel and complex and small oil passage. They are very sensitive to pollutants and temperature changes. If the necessary maintenance is lacking, the automatic transmission will have some malfunctions, such as rough work, difficult shifting and so on. According to statistics, 90% of the automatic transmission failures are caused by the deterioration of transmission fluid pollution.

传统的定期排放和加注自动变速器传动液会在液力变扭器和变速器的冷却管中残留75%以上的旧传动液,新的自动变速器传动液加入以后,立即被系统内的旧传动液污染,未被排出的沉积物会严重影响系统的工作性能。

Traditional regular discharge and filling of transmission fluids will leave more than 75% of the old transmission fluids in the cooling pipes of hydraulic torque converters and transmission. When new transmission fluids are added, they will be immediately polluted by the old transmission fluids in the system, and the unexploded sediments will seriously affect the performance of the system.

为达到彻底更换的目的,就需要使用自动变速器清洗剂来彻底清除旧液,保证100%更换自动变速器中的传动液,另外,还可以加入保护剂和止漏剂,这些工作较好使用设备来完成。
