和手動擋相比，自動變速箱在結構和使用上有很大不同。下面濟南自動變速箱維修廠家就來為您分析自動變速箱的結構特點內(nèi)容。

Compared with manual transmission, automatic transmission is very different in structure and use. Below, Jinan automatic transmission maintenance factory will analyze the structural characteristics of automatic transmission for you.

手動擋主要通過調(diào)節(jié)不同齒輪組合來更換擋位，而自動變速箱是通過液力傳遞和齒輪組合的方式來達到變速的目的。

The manual gear mainly changes gears by adjusting different gear combinations, while the automatic transmission achieves the purpose of speed change through hydraulic transmission and gear combination.

其中液力變扭器是自動變速箱具特點的部件，它由泵輪、渦輪和導輪等構件組成，泵輪和渦輪是一對工作組合，泵輪通過液體帶動渦輪旋轉(zhuǎn)，而泵輪和渦輪之間的導輪通過反作用力使泵輪和渦輪之間實現(xiàn)轉(zhuǎn)速差并實現(xiàn)變速變矩功能，對駕駛者來說，您只需要以不同力度踩住踏板，變速箱就可以自動進行擋位升降。

Among them, the hydraulic torque converter is a characteristic component of the automatic transmission. It is composed of components such as the pump wheel, turbine and guide wheel. The pump wheel and turbine are a pair of working combinations. The pump wheel drives the turbine to rotate through the liquid, and the guide wheel between the pump wheel and the turbine realizes the speed difference between the pump wheel and the turbine through the reaction force and realizes the variable speed torque function. For the driver, you only need to step on the pedal with different strength, The transmission can automatically move the gear up and down.

由于液力變矩器自動變速變矩范圍不夠大，因此在渦輪后面再串聯(lián)幾排行星齒輪提率，液壓操縱系統(tǒng)會隨發(fā)動機工作變化自行操縱行星齒輪，從而實現(xiàn)自動變速變矩。為了滿足行駛過程中的多種需要(如泊車、倒車)等，自動變速箱還設有一些手動撥桿位置，像P擋(停泊)、R擋(后擋)、N擋(空檔)、D擋(前進)等。

Since the automatic transmission and torque conversion range of the hydraulic torque converter is not large enough, several rows of planetary gears are connected in series behind the turbine to improve efficiency. The hydraulic control system will control the planetary gears according to the working changes of the engine, so as to realize automatic transmission and torque conversion. In order to meet various needs during driving (such as parking and reversing), the automatic transmission is also equipped with some manual paddle positions, such as P gear (parking), R gear (rear gear), n gear (neutral), D gear (forward), etc.

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。自動變速箱的動力響應不夠直接，這使它在“駕駛樂趣”方面稍顯不足。此外，由于采用液力傳動，這使自動擋變速箱傳遞的動力有所損失。

In terms of performance, the more gears the automatic transmission has, the smoother the car will be in the driving process, the better the acceleration and the more fuel-efficient it will be. In addition to providing a comfortable driving experience, the automatic transmission also has insurmountable defects. The power response of the automatic transmission is not direct enough, which makes it slightly insufficient in "driving pleasure". In addition, due to the hydraulic transmission, the power transmitted by the automatic transmission is lost.

自動變速器的保養(yǎng)方法：

Maintenance method of automatic transmission:

自動變速器需按照規(guī)定添加變速箱油。切不可因為貪圖便宜或方便，添加手動擋變速器機油，不然將會對離合器和制動器產(chǎn)生嚴重的燒蝕。在正規(guī)的自動變速器油里配置了適量的摩擦改良劑，它可以保證離合器與制動器能夠正常地工作。摩擦改良劑的數(shù)量是根據(jù)自動變速器能承受的負荷改變而改變的，并不存在一個恒定的數(shù)值。

The automatic transmission shall be filled with transmission oil as required. Do not add manual transmission oil for the sake of cheapness or convenience, otherwise it will cause serious erosion to the clutch and brake. A proper amount of friction improver is provided in the normal automatic transmission oil to ensure that the clutch and brake can work normally. The amount of friction improver varies according to the load that the automatic transmission can bear, and there is no constant value.

除了要按照規(guī)定添加外，還需要根據(jù)變速箱油的型號進行添加，否則將會出現(xiàn)離合器打滑、熱車跳檔等現(xiàn)象。更多相關事項就來我們網(wǎng)站http://m.566605.com咨詢了解。

In addition to adding according to the regulations, it is also necessary to add according to the model of transmission oil, otherwise the clutch will slip and the hot car will jump. For more information, please visit our website http://m.566605.com Consultation and understanding.
