自動變速箱，也稱為自動變速器，是一種能夠自動在不同駕駛條件下更換齒輪比的變速器。它主要由液力變矩器、行星齒輪組、液壓控制系統和電子控制系統組成。了解這些部件的功能對于進行有效的維修至關重要。

Automatic transmission, also known as automatic gearbox, is a type of transmission that can automatically change gear ratios under different driving conditions. It mainly consists of a hydraulic torque converter, planetary gear set, hydraulic control system, and electronic control system. Understanding the functions of these components is crucial for effective maintenance.

1. 液力變矩器： 液力變矩器是自動變速箱的核心部件，它負責將發動機的動力傳遞到變速箱。維修時，檢查其是否磨損或損壞是首要任務。

1. Hydraulic torque converter: The hydraulic torque converter is the core component of an automatic transmission, responsible for transmitting the power of the engine to the transmission. When repairing, checking for wear or damage is the primary task.

2. 行星齒輪組： 行星齒輪組負責根據駕駛條件自動更換齒輪比。維修時，需要檢查齒輪的磨損情況和同步器的工作狀態。

2. Planetary gear set: The planetary gear set is responsible for automatically changing the gear ratio according to driving conditions. During maintenance, it is necessary to check the wear of the gears and the working condition of the synchronizer.

3. 液壓控制系統： 液壓控制系統通過油壓來控制齒輪的切換。維修時，檢查油泵、閥門和油路是否堵塞或泄漏是必要的。

3. Hydraulic control system: The hydraulic control system controls the switching of gears through oil pressure. It is necessary to check whether the oil pump, valves, and oil circuit are blocked or leaking during maintenance.

4. 電子控制系統： 現代自動變速箱通常配備電子控制系統，以提高換擋的精確性和效率。維修時，需要檢查傳感器和控制模塊是否工作正常。

4. Electronic control system: Modern automatic transmissions are usually equipped with electronic control systems to improve the accuracy and efficiency of gear shifting. During maintenance, it is necessary to check whether the sensors and control modules are working properly.

維修注意事項：

Maintenance precautions:

清潔： 變速箱油是自動變速箱的血液，定期更換清潔的變速箱油可以延長變速箱的使用壽命。

Cleaning: Transmission oil is the lifeblood of automatic transmissions, and regularly replacing clean transmission oil can extend the service life of the transmission.

專業工具： 維修自動變速箱需要專業的工具和設備，以確保維修過程的安全性和準確性。

Professional tools: Repairing automatic transmissions requires specialized tools and equipment to ensure the safety and accuracy of the repair process.

診斷： 在進行維修前，使用專業的診斷工具進行故障診斷，以確定問題所在。

Diagnosis: Before carrying out repairs, use professional diagnostic tools to diagnose the problem and determine its location.

結語：

Conclusion:

自動變速箱維修需要專業知識和技能，對于車主來說，了解基礎知識有助于更好地維護和保養自己的車輛。

Automatic transmission maintenance requires professional knowledge and skills, and for car owners, understanding basic knowledge can help better maintain and upkeep their vehicles.
