作為修車一族來說，我們時常會遇上關(guān)于自動變速箱的故障問題，那么怎么樣才能快速準(zhǔn)確的判斷出問題所在呢?診斷的思路是怎么樣的?今天濟(jì)南自動變速箱維修人員來講講入檔遲、入檔死火、入檔沖擊是怎么回事。

As a car repairer, we often encounter problems with automatic transmission, so how can we quickly and accurately determine the problem? What is the idea of diagnosis? Today, Jinan automatic transmission maintenance personnel will talk about the reasons of late shift, misfire and shock.

測試入檔標(biāo)準(zhǔn)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(nèi)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，這是一部正常的入檔標(biāo)準(zhǔn)，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。

The test gear-in standard is to start the engine, idle, hold the brake, and shift in. The normal condition is to feel the gear-in within 1-1.2 seconds, release the brake pedal, and the vehicle will start slowly and gradually extract the speed of 10-20 km/h without stepping on the accelerator pedal. This is a normal gear-in standard. If the gear-in delay is located more than 2 seconds after the gear-in, 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(nèi)部有故障，但這個沖擊比較大則是不能夠接受的，引發(fā)的這個問題很復(fù)雜包括除變速箱以外的很多方面;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。

If there is a strong impact feeling in the gear shift, that is, the positioning impact, it should be noted that any automatic transmission has a certain degree of impact feeling in the gear shift. If there is no feeling at all, it indicates that there is an internal fault, but the impact is relatively large, which is unacceptable. The problem caused is very complex, including many aspects except the transmission; The case of misfire when shifting in is that the engine will misfire when shifting in. This problem is more obvious when the car is cold. This problem is caused by the gearbox and other body systems.

起步無力、不能起步、起步抖動測試起步的標(biāo)準(zhǔn)有兩個其一是測試“爬行”，其二是測試測試提速爬行是指入檔后放開剎車、不睬油門踏板、直路行駛測試在怠速情況下的車輛起步和行駛，正常的車輛能夠車輛逐步提速到20公里/小時的時速，如果不能夠達(dá)到這個標(biāo)準(zhǔn)一般先要檢查引擎怠速是否過低，正常的700轉(zhuǎn)左右，其二檢查是否輪胎氣壓是否過低，如果以上正常說明變速箱系統(tǒng)存在故障。

There are two standards for starting test: weak starting, unable to start, and starting jitter. One is to test "creep". The other is to test acceleration creep, which means to release the brake after entering gear, ignore the accelerator pedal, and drive the vehicle straight. The normal vehicle can gradually increase the speed to 20 km/h, and if it can not meet this standard, it is necessary to check whether the engine idle speed is too low, The second is to check whether the tire pressure is too low. If the above is normal, it indicates that there is a fault in the transmission system.

測量起步提速的方法是入檔、松剎車、按照小、中、大油門的程序分三次測試起步提速的感覺，正常的情況是車輛的車速同引擎的轉(zhuǎn)速保持一定的比例加速，具體感覺根據(jù)引擎排量的大小、車輛的重量、變速箱的檔位有很大的關(guān)聯(lián)，整個提速過程平穩(wěn)順暢、無抖動、無沖擊為正常。

The way to measure the starting acceleration is to shift in gear, release the brake, and test the feeling of starting acceleration in three times according to the procedure of small, medium and large throttle. The normal situation is that the vehicle speed keeps a certain proportion of the engine speed to accelerate. The specific feeling is closely related to the size of the engine displacement, the weight of the vehicle, and the gear of the transmission. The whole acceleration process is smooth, without jitter and impact.
