1、AT变速箱，AT变速箱是在每个档位之间都会有一个离合片，离合片的作用就是控制档位，能够达到换挡，现在我们平常使用的AT变速箱就是采用对离合器的进行的一个控制，然后运用到变速箱里面达到换挡。

1. AT gearbox, there is a clutch plate between each gear, and the function of the clutch plate is to control the gear and achieve shifting. The AT gearbox we usually use now is to control the clutch and then apply it to the gearbox to achieve shifting.

2、自动变速箱的原理是：通过液力传递和齿轮组合的方式来达到变速变矩。自动变速箱是由液力变扭器、行星齿轮、液压变距系统和液压操纵系统组成。

2. The principle of an automatic transmission is to achieve variable speed and torque through hydraulic transmission and gear combination. An automatic transmission is composed of a hydraulic torque converter, planetary gears, hydraulic pitch control system, and hydraulic control system.

3、自动挡汽车变速箱的工作原理是：利用行星齿轮机构进行变速，其能根据油门踏板程自动挡度和车速变化，自动地进行变速。变速箱又称变速器，是用来改变来自发动机的转速和转矩的机构，能固定或分挡改变输出轴和输入轴的传动比。

3. The working principle of an automatic car transmission is to use a planetary gear mechanism for speed change, which can automatically shift gears and speed changes according to the throttle pedal range. A gearbox, also known as a transmission, is a mechanism used to change the speed and torque from the engine. It can fix or shift gears to change the transmission ratio of the output and input shafts.
