自動變速箱是相對于手動變速箱而出現的一種能夠自動根據汽車車速和發動機轉速來進行自動換擋操縱的變速裝置，那么您對汽車變速箱了解嗎？下面濟南自動變速箱維修人員就來為您簡單講解一下這個問題。

The automatic transmission is a kind of transmission device that can automatically shift according to the vehicle speed and engine speed, compared with the manual transmission. Do you know about the automobile transmission? Now Jinan automatic transmission maintenance personnel will explain this problem for you briefly.

1、汽車的變速箱是汽車的主要傳動部件，在發動機旋轉方向不變情況下，變速箱能利用空擋中斷動力傳遞，以使發動機能夠起動、怠速，并便于變速器換擋或進行動力輸出，變速箱也能使汽車倒退行駛；

1. The gearbox of an automobile is the main transmission part of the automobile. When the rotation direction of the engine is unchanged, the gearbox can interrupt power transmission by using neutral gear to enable the engine to start and idle, and facilitate the transmission to shift gears or output power. The gearbox can also make the automobile run backward;

2、變速箱分為手動、自動兩種，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；而自動變速箱AT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；

2. Gearboxes are divided into manual and automatic ones. Manual gearboxes are mainly composed of gears and shafts, which generate variable speed and torque through different gear combinations; The automatic transmission AT is composed of hydraulic torque converter, planetary gear and hydraulic control system, which can achieve variable speed and torque through hydraulic transmission and gear combination;

3、汽車變速箱的作用，改變傳動比，擴大驅動輪轉矩和轉速的變化范圍，以適應經常變使汽車能倒退行駛；化的行駛條件，同時使發動機在功率較高而油耗較低）的工況下工作；

3. The function of the automobile gearbox is to change the transmission ratio, expand the variation range of the torque and speed of the driving wheel, so as to adapt to the frequent changes and enable the automobile to run backward; The driving conditions are optimized to enable the engine to work under the conditions of high power and low fuel consumption);

4、在發動機旋轉方向不變情況下，使汽車能倒退行駛，利用空擋，中斷動力傳遞，以發動機能夠起動、變速，并便于變速器換擋或進行動力輸出。

4. Under the condition that the rotation direction of the engine remains unchanged, the vehicle can be driven backward. The neutral gear is used to interrupt the power transmission, so that the engine can start and change speed, and it is convenient for the transmission to shift or output power.

汽車變速箱能改變傳動比，擴大驅動輪轉矩和轉速的變化范圍，以適應經常變化的行駛條件，同時使發動機在有利（速度較高而油耗較低）的工況下工作；另外在發動機旋轉方向不變情況下，使汽車能倒退行駛；變速箱還能利用空擋，中斷動力傳遞，使發動機能夠起動、怠速，并便于變速器換擋或進行動力輸出。

The automobile gearbox can change the transmission ratio, expand the variation range of the torque and speed of the driving wheel to adapt to the constantly changing driving conditions, and enable the engine to work under favorable conditions (high speed and low fuel consumption); In addition, under the condition that the rotation direction of the engine remains unchanged, the vehicle can be driven backward; The transmission can also use neutral gear to interrupt power transmission, enabling the engine to start and idle, and facilitating transmission shifting or power output.

此外從性能上說自動變速箱的擋位越多，車在行駛過程中也就越平順，加速性也越好，而且更加省油。除了提供輕松愜意的駕駛感受，自動變速箱也有無法克服的缺陷。所以要定期對其進行保養維修才是。更多注意事項就來我們網站http://www.566605.com咨詢吧！

In addition, in terms of performance, the more gears the automatic transmission has, the smoother the car will be when driving, the better the acceleration and the more fuel efficient it will be. In addition to providing a comfortable driving experience, automatic transmissions also have insurmountable defects. Therefore, it is necessary to maintain them regularly.
