常有車主反映，車輛在升擋、降擋過(guò)程中有沖擊、頓挫感，或是在加速時(shí)出現(xiàn)卡頓慫車的感覺(jué)。這就是我們常說(shuō)的變速箱頓挫。這是自動(dòng)擋汽車行駛到一定里程常出現(xiàn)的現(xiàn)象。下面山東變速箱維修人員為您講解下這個(gè)方面。

The car owners often report that the car has a feeling of shock and frustration during upshifting and downshifting, or a feeling of being stuck when accelerating. This is what we often say about the gearbox. This is a common phenomenon when an automatic transmission vehicle runs to a certain mileage. Next, Shandong transmission maintenance personnel will explain this aspect to you.

1、頓挫原因分析

1. Analysis of the causes of setbacks

出現(xiàn)頓挫的原因主要有二，一是電磁閥異常，導(dǎo)致電磁閥異常的原因較多，可能變速箱油變質(zhì)，導(dǎo)致閥體部件磨損而產(chǎn)生雜質(zhì)致使電磁閥無(wú)法正常調(diào)節(jié)油壓；也可能是本身設(shè)備的故障率導(dǎo)致自然損傷。二是閥體閥道損傷，這個(gè)階段的情況就較為嚴(yán)重了，變速箱內(nèi)部進(jìn)一步磨損產(chǎn)生的頑固雜質(zhì)，將使閥道閥芯卡漬，同時(shí)產(chǎn)生磨損，故障更加嚴(yán)重。

There are two main reasons for the setback. First, the solenoid valve is abnormal. There are many reasons that cause the solenoid valve to be abnormal. It may be that the gearbox oil is deteriorated, causing the valve body parts to wear and produce impurities, which makes the solenoid valve unable to regulate the oil pressure normally; It may also be the failure rate of the equipment itself that causes natural damage. Second, the valve channel of the valve body is damaged, and the situation at this stage is more serious. The stubborn impurities generated by the further wear inside the gearbox will cause the valve channel and the valve core to be stuck, at the same time, the wear will occur, and the fault will be more serious.

2、是否需要維修

2. Whether maintenance is required

頓挫故障在大部分情況下需要通過(guò)維修才能解決。如果是閥體其他地方磨損的雜質(zhì)干擾到電磁閥部件信號(hào)異常，這種情況通過(guò)專門的維修有可能恢復(fù)電磁閥的正常工作。

The stuttering fault can only be resolved through maintenance in most cases. If the worn impurities in other parts of the valve block interfere with the abnormal signal of the solenoid valve components, the normal operation of the solenoid valve may be restored through special maintenance.

如果因?yàn)殡姶砰y自身的故障率導(dǎo)致自然損傷，則一般需要對(duì)電磁閥進(jìn)行更換。如果閥體內(nèi)部閥道磨損嚴(yán)重，嚴(yán)重影響變速箱油壓正常控制，頓挫現(xiàn)象更加嚴(yán)重，這種情況一般會(huì)選擇更換閥體。

If the failure rate of the solenoid valve itself causes natural damage, it is generally necessary to replace the solenoid valve. If the valve channel inside the valve body is seriously worn, which seriously affects the normal control of transmission oil pressure, and the bumping is even more serious, the valve body will generally be replaced.

頓挫故障在初期，如果對(duì)電磁閥采用清洗或調(diào)節(jié)等維修手法就能解決問(wèn)題，在費(fèi)用上基本以人工費(fèi)為主。如果需要更換電磁閥，一般只需幾百元。如果因?yàn)轭D挫過(guò)于嚴(yán)重，需要更換閥體，其價(jià)格一般需要兩三千元或以上，具體價(jià)格以各品牌實(shí)時(shí)報(bào)價(jià)為準(zhǔn)。相關(guān)內(nèi)容就來(lái)我們網(wǎng)站http://www.566605.com進(jìn)行咨詢吧！

In the early stage of the setback, if the solenoid valve is cleaned or adjusted, the problem can be solved. The cost is mainly labor cost. If the solenoid valve needs to be replaced, it usually costs only a few hundred yuan. If the valve body needs to be replaced due to too serious setback, the price will generally cost two or three thousand yuan or more, and the specific price shall be subject to the real-time quotation of each brand.
