很多車主們對于車輛自動變速箱的保養(yǎng)維護知識卻知之甚少，開車過程中不注意維護保養(yǎng)，變速箱很容易發(fā)生故障。現(xiàn)在來講講關于變速箱入檔遲、入檔死、入檔沖擊的故障分析吧。
Many car owners know little about the maintenance of the automatic transmission. If they don't pay attention to maintenance during driving, the transmission is prone to failure. Now let's talk about the fault analysis of the late shift, dead shift and shock shift of the transmission.
故障情況：測試入檔標準是啟動引擎、怠速、踩住剎車、入檔，正常的的情況是1－1.2秒的時間內有入檔的感覺、放開剎車踏板，在不踩油門踏板的情況下車輛會慢慢起步并逐步提取到10－20公里/小時的車速，這是正常的入檔標準，如果入檔后超過2秒鐘以上即定位入檔延遲，這種情況需要立即檢修。
Fault condition: the test gearing standard is to start the engine, idle, step on the brake, and gear in. The normal situation is to feel gearing in 1-1.2 seconds and release the brake pedal. Without stepping on the accelerator pedal, the vehicle will start slowly and gradually extract the speed of 10-20 km / h. This is the normal gearing standard. If the gearing is more than 2 seconds after gearing, the gearing delay will be positioned. This situation needs to be repaired immediately.
如果入檔有強烈的沖擊感覺即定位入檔沖擊，需要說明的是任何的自動變速箱入檔都有一定程度的沖擊感覺，如果絲毫的感覺都沒有，反而說明內部有故障，但這個沖擊比較大是不能夠接受的，而引發(fā)的這個問題的原因就很復雜而且包括除了變速箱以外的很多方面。
If there is a strong impact feeling in gear, that is, the positioning impact, it should be noted that any automatic transmission has a certain degree of impact feeling in gear. If there is no feeling at all, it indicates that there is an internal fault, but the impact is relatively large, which is unacceptable, and the causes of this problem are very complex and include many aspects except the gearbox.
入檔死火的情況是入檔時引擎會死火，這種問題在冷車時比較明顯，引發(fā)這個問題有變速箱的問題也有其他車身系統(tǒng)的問題。
The situation of stalling in gear is that the engine will stall in gear. This problem is more obvious when the car is cold. This problem is caused by the gearbox and other body systems.
此外車輛跑不起包括沒有高速，即無論如何行駛，車輛都不能達到100公里/小時個速段。提速很慢，即油門踩的很重但車輛還是慢慢提速，反應很差、缺乏酣暢的感覺，這種情況又包括引擎提速慢，即發(fā)動機的轉速上不來和轉速上得很快但車速不快這兩種情況。
In addition, the vehicle can't afford to run, including no high-speed, that is, no matter how you drive, the vehicle can't reach the speed range of 100 km / h. The acceleration is very slow, that is, the accelerator is pressed heavily, but the vehicle still accelerates slowly, with poor response and lack of sound feeling. This situation also includes the slow acceleration of the engine, that is, the speed of the engine does not come up and the speed of the engine is fast but the speed is not fast.
所以這是個非常復雜的問題，正常的測試標準是車輛起步、適當踩加速踏板，引擎轉速平穩(wěn)提升，車輛加速，一般在2500轉左右，車速在25－30公里之間，自動變速箱進入換檔，引擎的轉速在適當回落后逐步回升。
So this is a very complex problem. The normal test standard is to start the vehicle, step on the accelerator pedal appropriately, the engine speed increases steadily, the vehicle accelerates, generally around 2500 rpm, the speed is between 25-30 km, the automatic transmission enters the first shift, and the engine speed gradually picks up after an appropriate drop.
同時車速明顯加快，在車輛40公里時二次換檔，變速箱在進入三檔后，車速會進一步加快，在60公里的速段上會進入變速箱的高檔位，整個過程引擎在升檔的過程會適當回落后再次提起，無空轉、無打滑現(xiàn)象。
At the same time, the vehicle speed is significantly accelerated. When the vehicle is shifted for a second time at 40 km, the speed of the transmission will further accelerate after entering the third gear, and will enter the high gear of the transmission at the speed range of 60 km. In the whole process, the engine will be lifted again after appropriately falling back in the process of upshifting, without idling and slipping.
濟南自動變速箱維修人員認為一般引擎排量位2.0左右排量的車輛平穩(wěn)行駛的情況下，引擎2500－3000轉時車速可以達到100公里的時速，如需要進一步提升車速，引擎轉速需要同步增加。如果引擎加油很悶、不順暢一般說明引擎需要檢修，如果引擎加速有力則說明變速箱內部檔位不對、離合器燒毀、變鈕器出現(xiàn)機械故障等。
Jinan automatic transmission maintenance personnel believe that generally, when the engine displacement is about 2.0, the vehicle speed can reach 100 kilometers per hour when the engine is 2500-3000 rpm. If the speed needs to be further increased, the engine speed needs to be increased synchronously. If the engine is stuffy and does not refuel smoothly, it generally indicates that the engine needs maintenance. If the engine accelerates strongly, it indicates that the internal gear of the gearbox is wrong, the clutch is burned, and the button changer has mechanical failure.
You should know that once there is a problem with the automatic transmission, it is also very troublesome to repair, so ordinary maintenance is a very important thing. Come to our website for more relevant content http://m.ihudie.cn Consult!
