When you buy a car now, you often hear such a sentence: "buy a car, buy an automatic baffle. Gearbox maintenance has different transmission ratios for each gear position, which is equivalent to the simultaneous interpreting of the meshing between the pinion and the big gear. The low transmission ratio (3 gears and below) can be obtained at low speed, and the greater shaft speed is lower than the engine speed. The greater driving force can be obtained. When the speed is high, the high transmission ratio (4 gears and above), the shaft speed is higher than the engine speed, and the traction force can be reduced more quickly. Gear shifting means that gears of different sizes are selected to mesh with gears of main shaft.

雖然汽車在使用時(shí)不像手動(dòng)齒輪那樣復(fù)雜，但它并不完全需要駕駛汽車，但它并不完全需要駕駛汽車，如果自動(dòng)變速箱不能正常運(yùn)行，它也會(huì)增加自動(dòng)變速箱故障的可能性。此時(shí)需要自動(dòng)變速器服務(wù)。

Although the automobile is not as complicated as manual gear in use, it does not need to drive the car completely, but it does not need to drive the car completely. If the automatic transmission can not operate normally, it will also increase the possibility of automatic transmission failure. Automatic transmission service is required at this time.

自動(dòng)變速器稱為AT。它由三個(gè)重要部分組成：液力變矩器，行星齒輪和液壓控制系統(tǒng)。液壓傳動(dòng)和齒輪組合用于快速實(shí)現(xiàn)變速扭矩。不同道路上的模型自動(dòng)變速器可以自動(dòng)改變扭矩，自動(dòng)變速器不能分離，就像馭勝S350，它與ZF的6AT變速器相匹配，這款6AT變速箱成熟穩(wěn)定，有多種駕駛模式，穩(wěn)定性和操控性都很好，允許駕駛員專注于道路交通而不會(huì)被換擋困擾。

Automatic transmission is called at. It consists of three important parts: hydraulic torque converter, planetary gear and hydraulic control system. The combination of hydraulic drive and gear is used to quickly realize variable speed torque. The model automatic transmission on different roads can automatically change the torque, and the automatic transmission can not be separated. Just like Yusheng S350, it is matched with ZF's 6at transmission. This 6at gearbox is mature and stable, has a variety of driving modes, and has good stability and handling. It allows the driver to focus on road traffic without being bothered by shifting gears.

如果您的車出現(xiàn)以下現(xiàn)象，說明您的車需要及時(shí)修理，否則會(huì)損壞車輛的傳動(dòng)裝置。以下情況會(huì)導(dǎo)致自動(dòng)變速器的損壞，使用汽車時(shí)要注意這些點(diǎn)。

If your car appears the following phenomenon, it means that your car needs to be repaired in time, otherwise the transmission device of the vehicle will be damaged. The following conditions will cause damage to the automatic transmission. Pay attention to these points when using the car.

一、箱體內(nèi)有異味

1、 There is a peculiar smell in the box

自動(dòng)傳動(dòng)結(jié)構(gòu)一般不同于齒輪組機(jī)構(gòu)和手動(dòng)變速。其結(jié)構(gòu)包含多組摩擦片和剎車片。這些零部件需要液壓油來維持工作。液壓油的溫度直接決定傳動(dòng)是否能正常運(yùn)行。如果油過熱，會(huì)引起一些燃燒。這些氣味會(huì)擴(kuò)散開來，這意味著變速箱中的一些執(zhí)行部件無法正常工作，或液壓油不足以及時(shí)加入自動(dòng)變速箱油。選擇加入液壓油時(shí)，盡量選擇原裝油，以保持變速箱的良好性能，延長(zhǎng)變速箱的使用壽命。

Automatic transmission structure is generally different from gear set mechanism and manual speed change. The structure comprises a plurality of friction plates and brake pads. These parts need hydraulic oil to keep working. The temperature of hydraulic oil directly determines whether the transmission can run normally. If the oil is overheated, it will cause some combustion. These odors can spread, which means that some of the actuating components in the transmission are not working properly or the hydraulic oil is not enough to fill the automatic transmission oil in time. When choosing to add hydraulic oil, the original oil should be selected as far as possible to maintain the good performance of the gearbox and extend the service life of the gearbox.

第二，自動(dòng)換檔時(shí)間過長(zhǎng)或太短

Second, the automatic shift time is too long or too short

自動(dòng)變速器通常具有特定的變速速度和速度。如果你改變換檔過程，你顯然覺得換檔時(shí)間太長(zhǎng)或太短，這意味著變速箱的傳動(dòng)是不成比例的。更進(jìn)一步，可能存在發(fā)動(dòng)機(jī)轉(zhuǎn)速過高且變速箱不換檔的情況。如果發(fā)現(xiàn)換檔時(shí)間異常，應(yīng)及時(shí)將其發(fā)送給維修。

Automatic transmission usually has a specific speed and speed. If you change the shift process, you obviously feel that the shift time is too long or too short, which means that the transmission of the transmission is out of proportion. Further, it is possible that the engine speed is too high and the transmission does not shift. If it is found that the shift time is abnormal, it should be sent to.

三、車子起步困難

3、 It's difficult to start the car

當(dāng)然，并非所有的起動(dòng)困難都是自動(dòng)變速器異常。在冬季，由于低溫，車輛起動(dòng)困難是很常見的。起動(dòng)困難是指在起動(dòng)車輛時(shí)，無論掛上什么檔位，車輛都不走，或發(fā)動(dòng)機(jī)轉(zhuǎn)速很高，但速度很慢，這可能是自動(dòng)變速器的異常情況。

Of course, not all starting difficulties are caused by abnormal automatic transmission. In winter, it is very common for the vehicle to start because of low temperature. Starting difficulty refers to that when starting the vehicle, no matter what gear is engaged, the vehicle does not go, or the engine speed is very high, but the speed is very slow. This may be an abnormal condition of automatic transmission.

四、掛擋時(shí)發(fā)動(dòng)機(jī)熄火

4、 The engine stalls when the gear is in gear

我們都知道，自動(dòng)汽車不像手動(dòng)汽車，一般不關(guān)閉發(fā)動(dòng)機(jī)。如果你掛上電話的時(shí)候關(guān)掉了發(fā)動(dòng)機(jī)，那就意味著自動(dòng)變速器出了問題。

As we all know, an automatic car, unlike a manual car, generally does not turn off the engine. If you turn off the engine when you hang up the phone, it means there is something wrong with the automatic transmission.

自動(dòng)變速箱維修自動(dòng)變速器的核心在實(shí)現(xiàn)自動(dòng)換擋。所謂自動(dòng)換擋是指汽車在行駛的過程中，駕駛員按行駛過程的需要操控加速踏板（油門踏板），自動(dòng)變速器即可根據(jù)發(fā)動(dòng)機(jī)負(fù)荷和汽車的運(yùn)行工況，自動(dòng)換入不同擋位工作。”自動(dòng)攔路車操作簡(jiǎn)單方便，深受消費(fèi)者歡迎。當(dāng)你買車時(shí)，你會(huì)更傾向于買自動(dòng)擋板模型。

Automatic transmission maintenance the core of automatic transmission is to realize automatic shift. The so-called automatic shift refers to that in the process of driving, the driver controls the accelerator pedal (accelerator pedal) according to the needs of the driving process, and the automatic transmission can automatically shift into different gears according to the engine load and the operating conditions of the car. " The operation of automatic road blocking vehicle is simple and convenient, which is welcomed by consumers. When you buy a car, you're more likely to buy an automatic fender model.
