　　Automatic transmission is a type of vehicle transmission system that can automatically adjust the gear ratio based on factors such as vehicle speed and RPM, thereby keeping the engine in optimal working condition, improving fuel efficiency, and driving comfort. Automatic transmission is more convenient and easy to use compared to manual transmission, and is a commonly used transmission in modern cars.|

　　1.自動(dòng)變速箱的工作原理

　　1. Working principle of automatic transmission

　　自動(dòng)變速箱的工作原理基于液力傳動(dòng)的原理，即通過(guò)油液流動(dòng)來(lái)實(shí)現(xiàn)齒輪的切換和傳動(dòng)。自動(dòng)變速箱包括液壓系統(tǒng)、離合器、行星齒輪組等部分，其中液壓系統(tǒng)是其核心部分。當(dāng)發(fā)動(dòng)機(jī)轉(zhuǎn)速達(dá)到一定值時(shí)，液壓系統(tǒng)會(huì)將動(dòng)力傳輸?shù)叫行驱X輪組中，從而進(jìn)行換擋操作，使得車輛保持在最佳工作狀態(tài)。

　　The working principle of an automatic transmission is based on the principle of hydraulic transmission, which achieves gear switching and transmission through the flow of oil. The automatic transmission includes hydraulic system, clutch, planetary gear set and other parts, among which the hydraulic system is its core component. When the engine speed reaches a certain value, the hydraulic system will transmit power to the planetary gear set to perform gear shifting operations, keeping the vehicle in optimal working condition.
