通過齒數不同的齒輪組合就可以實現增速或減速。這就好比我們騎的山地車，就運用了這一原理，通過不同的齒輪組合達到變速和變矩的目的。
Through gear combination with different number of teeth, speed increase or deceleration can be achieved. This is just like the mountain bike we ride on. This principle is applied to achieve the purpose of speed and torque by different gear combinations.
濟南自動變速箱維修是由液力變扭器、行星齒輪和液壓操縱系統組成，通過液力傳遞和齒輪組合的方式來達到變速變矩。
The maintenance of Ji'nan automatic transmission is made up of hydraulic torque converter, planetary gear and hydraulic control system, which can achieve variable torque change by means of hydraulic transmission and gear combination.
手動變速箱主要由齒輪和軸組成，通過不同的齒輪組合產生變速變矩。換擋的原理其實很簡單，齒輪轉動時，齒數較小的A齒輪轉速>B齒輪，則驅動力AB。

Manual gearboxes are mainly composed of gears and shafts, generating variable speed torque through different gear combinations. The principle of shifting is actually very simple. When the gear is rotated, the smaller A gear speed > B gear, the driving force is A < B; the A gear speed of the larger number of teeth is less than B gear, and the driving force A > B.
改變傳動比，以適應不同的行駛速度和行駛條件;發動機旋轉方向不變情況下，使汽車能倒退行駛;
Changing the transmission ratio to adapt to different driving speed and driving conditions; and when the engine rotation direction is constant, the vehicle can go backward.
利用空擋，中斷動力傳遞，且使發動機停留在怠速的狀態。這樣的好處是可以提高引擎的傳動效率。換句話說，就是用更少的油跑更遠的路。
The use of neutral gear interrupts power transmission and keeps the engine at idle speed. This advantage can improve the transmission efficiency of the engine. In other words, running farther away with less oil.
