自動變速箱的問世，減輕了駕駛員駕駛汽車時的緊張感。四檔自動變速箱換檔操縱桿及檔位。下面山東變速箱維修廠家來講講四檔自動變速箱換檔操縱桿及檔位的事項！檔位符號分別為P、R、N、D、3、2、1。

With the advent of automatic transmission, drivers feel less nervous when driving. Shift control lever and gear of four-speed automatic transmission. Next, Shandong transmission maintenance manufacturer will talk about the shift lever and gear of the four-speed automatic transmission! The gear symbols are P, R, N, D, 3, 2 and 1.

P（PARK）—停車檔

P (PARK) - parking gear

出于安全原因，離車前一定要將換檔桿置于檔位P，在進行維修時，特別是在發(fā)動機運轉時，更是如此。

For safety reasons, the shift lever must be placed in gear P before leaving the vehicle, especially when the engine is running.

在檔位P時，自動變速箱處在空檔，機械杠桿會將輸出軸鎖死，以防止溜車現(xiàn)象發(fā)生，當然只有在車輛完全停穩(wěn)時，方可將換檔桿置于檔位P。

In gear P, when the automatic transmission is in neutral, the mechanical lever will lock the output shaft to prevent rolling. Of course, the shift lever can be put in gear P only when the vehicle is completely stopped.

R（REVERSE）—倒車檔

R (REVERSE) - reverse gear

只有在車輛完全停穩(wěn)后，方可掛入或退出檔位R，否則會造成自動變速箱的早期磨損。

Only after the vehicle has completely stopped, can it shift into or out of gear R, otherwise it will cause early wear of the automatic transmission.

N（Neutral）—空檔

N (Neutral) - Neutral

如果需要推動或牽引車輛，則必須選用檔位N，在牽引車輛時，牽引速度不應大于50km/h，牽引距離不應大于50km，否則，會損壞自動變速箱的行星齒輪機構。

If it is necessary to push or tow the vehicle, gear N must be selected. When towing the vehicle, the traction speed should not be greater than 50km/h and the traction distance should not be greater than 50km, otherwise, the planetary gear mechanism of the automatic transmission will be damaged.

在車輛靜止，點火開關接通的情況下，必須踏下制動踏板并按下?lián)Q檔桿側面按鈕方可移出檔位N。在車輛行駛過程中，車速>5km/h，只需按下?lián)Q檔桿側面按鈕，即可移出或換入檔位N。

When the vehicle is stationary and the ignition switch is on, the brake pedal must be pressed and the button on the side of the shift lever pressed to move out of gear N. When the vehicle speed is>5km/h during driving, just press the button on the side of the shift lever to move out or into gear N.

D（DRIVE）—行駛檔

D (DRIVE) - Drive

只有踏下制動踏板并按下?lián)Q檔桿側面的按鈕，方可將變速桿從檔位P或N移出，換入行駛檔位。檔位D是常用的檔位，在檔位D，自動變速箱首先選擇一檔使車輛起步，然后根據(jù)油門開度和車速等信號，在適當時刻逐漸升至一檔、三檔直至四檔。同樣，車輛減速時，自動變速箱也會自動地從相應檔位降檔。

Only when the brake pedal is pressed and the button on the side of the shift lever is pressed can the shift lever be moved from gear P or N to the driving gear. Gear D is the commonly used gear. In gear D, the automatic transmission first selects the first gear to start the vehicle, and then gradually rises to the first gear, the third gear and the fourth gear at the appropriate time according to the throttle opening and vehicle speed and other signals. Similarly, when the vehicle decelerates, the automatic transmission will automatically downshift from the corresponding gear.

3—坡度檔

3 - Grade scale

如選擇檔位3，則行駛中只允許變速箱高升至3檔，如遇坡路可選用此檔，此時自動變速箱將在1、2、3三個檔位中自動實現(xiàn)換檔。在下坡路段時，選用此檔，可以利用發(fā)動機的制動效果。

If gear 3 is selected, the transmission is only allowed to rise to gear 3 during driving. This gear can be selected in case of a slope. At this time, the automatic transmission will automatically shift gears 1, 2 and 3. When selecting this gear on the downhill section, the braking effect of the engine can be used.

2—長坡檔

2 - Long slope

如選擇檔位2，則行駛中只允許變速箱高升至2檔，沿多彎道長坡路段行駛時，這個檔位非常有用，否則，自動變速箱可能會頻繁地更換檔位，下坡時選用此檔，可以利用發(fā)動機制動。

If gear 2 is selected, the transmission is only allowed to rise to gear 2 during driving. This gear is very useful when driving along the long slope section with multiple curves. Otherwise, the automatic transmission may change gear frequently. When selecting this gear when going downhill, the engine brake can be used.

1—陡坡檔

1 - Steep grade gear

選用檔位1，車輛則始終以1檔行駛，變速箱不會升入其他檔位，從而，可大限度地發(fā)揮發(fā)動機的制動力，因此，在下陡坡時，可以選用此檔。檔位1只能在車速低于30km/h時，方可選取。

If gear 1 is selected, the vehicle will always drive in gear 1, and the transmission will not move into other gears, so the braking force of the engine can be fully exerted. Therefore, this gear can be selected when going down a steep slope. Gear 1 can only be selected when the vehicle speed is lower than 30 km/h.

當自動變速箱電子控制系統(tǒng)出現(xiàn)故障時，自動變速箱處于應急工況，此時，自動變速箱只有R、3、l三個檔位，這時必須馬上去特約服務站進行維修，不可耽擱，否則，會造成較大的損失。您有什么問題或者需求可以隨時來我們網(wǎng)站http://www.ihudie.cn進行咨詢了解！

When the electronic control system of the automatic transmission fails, the automatic transmission is in the emergency condition. At this time, the automatic transmission has only three gears, R, 3 and l. At this time, you must go to the special service station for maintenance immediately, without delay, otherwise, it will cause great losses. If you have any questions or needs, please come to our website at any time http://www.ihudie.cn Consult and understand!
