隨著科技的不斷發展，人們為了方便，研制出很多自動產品。其中較為人熟知的便是汽車中的自動變速箱。了解自動變速箱的工作原理后，會對您日后在變速箱維護上大有幫助。
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.

如果你開過自動檔的車的話，你就知道自動檔和手動檔有兩大區別自動檔不像手動，沒有離合器自動檔不用換檔，把檔把撥到DRIVE D檔就行。自動變速箱(加上扭矩轉換器TORQUE CONVERTER，有的地方叫它濕式離合器) 和手動變速箱(加上離合器) 用完全不同的方法做到了相同的功用。手動變速箱一樣，自動變速箱的主要作用就是把引擎的輸出變換出很大的速度變化范圍輸出到驅動輪上。手動和自動變速箱之間一個很重要的不同就是，手動變速箱通過把不同直徑的齒輪鎖住到輸出軸上來達到改變齒輪比，而自動變速箱卻用同一組齒輪的不同排列來產生不同的齒輪比。那組齒輪叫做行星齒輪。一個自動變速箱是兩個行星齒輪組合在一起組成的一個整體。
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.
世界變速器行業發展趨勢分析 世界變速器行業發展趨勢分析 汽車行駛的速度是不斷變化的，這就要求汽車的變速器的變速比要盡量多，這就是無級變速(Continuously VariableTransmission簡稱 CVT )。盡管傳統的齒輪變速箱并不理想，但其以結構簡單、效率高、功率大三大顯著優點依然占領著汽車變速箱的主流地位。在跨越了三個世紀的一百多年后的今天，汽車還沒有使用上滿意的無級變速箱。這是汽車的無奈和缺憾。但是，人們始終沒有放棄尋找實現理想汽車變速器的努力，各大汽車廠商對無級變速器(CVT)表現了極大的熱情，極度重視CVT在汽車領域的實用化進程。這是世界范圍尚未根本解決的難題，也是汽車變速器的研究的目標。
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.
