随着科技的不断发展，人们为了方便，研制出很多自动产品。其中较为人熟知的便是汽车中的自动变速箱。了解自动变速箱的工作原理后，会对您日后在变速箱维护上大有帮助。
With the continuous development of science and technology, people have developed many automatic products for convenience. The most well-known one is the automatic transmission in a car. Knowing the working principle of the automatic transmission will help you in gearbox maintenance in the future.

如果你开过自动档的车的话，你就知道自动档和手动档有两大区别自动档不像手动，没有离合器自动档不用换档，把档把拨到DRIVE D档就行。自动变速箱(加上扭矩转换器TORQUE CONVERTER，有的地方叫它湿式离合器) 和手动变速箱(加上离合器) 用完全不同的方法做到了相同的功用。手动变速箱一样，自动变速箱的主要作用就是把引擎的输出变换出很大的速度变化范围输出到驱动轮上。手动和自动变速箱之间一个很重要的不同就是，手动变速箱通过把不同直径的齿轮锁住到输出轴上来达到改变齿轮比，而自动变速箱却用同一组齿轮的不同排列来产生不同的齿轮比。那组齿轮叫做行星齿轮。一个自动变速箱是两个行星齿轮组合在一起组成的一个整体。
If you have opened an automatic car, you know that there are two different types of automatic and manual gear unlike manual, no clutch gear without gear shift, and put the file to DRIVE D. Automatic transmission (coupled with torque converter TORQUE CONVERTER, some place called wet clutch) and manual transmission (plus clutch) do the same function in a completely different way. Like manual gearboxes, the main function of automatic gearboxes is to transform the output of the engine to a wide range of speed variations output to the drive wheel. A very important difference between the manual and the automatic transmission is that the manual transmission can change the gear ratio by locking the gears of different diameters to the output axis, while the automatic transmission produces different gear ratios with the different arrangement of the same gear. That group of gears is called a planetary gear. An automatic transmission is a combination of two planetary gears.
世界变速器行业发展趋势分析 世界变速器行业发展趋势分析 汽车行驶的速度是不断变化的，这就要求汽车的变速器的变速比要尽量多，这就是无级变速(Continuously VariableTransmission简称 CVT )。尽管传统的齿轮变速箱并不理想，但其以结构简单、效率高、功率大三大显著优点依然占领着汽车变速箱的主流地位。在跨越了三个世纪的一百多年后的今天，汽车还没有使用上满意的无级变速箱。这是汽车的无奈和缺憾。但是，人们始终没有放弃寻找实现理想汽车变速器的努力，各大汽车厂商对无级变速器(CVT)表现了极大的热情，极度重视CVT在汽车领域的实用化进程。这是世界范围尚未根本解决的难题，也是汽车变速器的研究的目标。
The development trend of the world transmission industry analysis of the development trend of the world transmission industry analysis of the speed of vehicle driving is constantly changing, which requires that the speed ratio of the automobile transmission is as much as possible, this is the Continuously VariableTransmission (CVT). Although the traditional gear gearbox is not ideal, but its simple structure, high efficiency and high power still occupy the main position of the automobile gearbox. Today, after more than 100 years spanning three centuries, the automobile has not yet used satisfactory CVT. This is the car's helplessness and regret. However, people have never given up the effort to find the ideal vehicle transmission, and the major automobile manufacturers have shown great enthusiasm for the CVT and attach great importance to the practical process of CVT in the automotive field. This is a difficult problem that has not been solved fundamentally in the world. It is also the ultimate goal of vehicle transmission research.
