汽車是現(xiàn)在人們出行的重要交通工具，隨著人們生活水平的不斷提高，汽車成為生活的必須品，使用過(guò)多，平時(shí)的保養(yǎng)也是必須的很多人都是平時(shí)會(huì)不太注意，也許就有可能會(huì)導(dǎo)致大的毛病，那么變速箱故障根源高溫如何處理？
Automobile is an important means of transportation for people to travel. With the continuous improvement of people's living standards, automobile has become a necessity of life. It is also necessary to use it too much. Many people do not pay much attention to it at ordinary times, which may lead to major problems. How to deal with the high temperature at the root of gearbox failure?
之所以4s店或?qū)Ｐ薜旮悴欢ㄗ兯傧涔收?，?dòng)不動(dòng)采取外科手術(shù)式的大拆大修，是因?yàn)樗麄儾⒉恢赖降资鞘裁匆l(fā)了變速箱故障，治標(biāo)不治本，沒效果并不稀奇。
The reason why 4S stores or special repair shops can't fix the gearbox failure and often take surgical overhaul is that they don't know what caused the gearbox failure. It's not uncommon to treat the symptoms but not the root cause.
根據(jù)自動(dòng)變速箱修理協(xié)會(huì)數(shù)據(jù)稱：“在所有自動(dòng)變速箱故障中有90%以上是高溫過(guò)熱導(dǎo)致的。”汽車啟動(dòng)不久后，自動(dòng)變速箱油溫度會(huì)升高。當(dāng)爬坡、高溫環(huán)境、持續(xù)的超高速行駛，市區(qū)內(nèi)走走停停時(shí)，自動(dòng)變速箱油溫度會(huì)超出安全溫度（80℃）。
According to the data of the automatic transmission repair Association, "more than 90% of all automatic transmission failures are caused by high temperature and overheating." Soon after the car starts, the temperature of the automatic transmission oil will rise. In case of climbing, high temperature environment, continuous ultra-high speed driving and stop and go in the urban area, the automatic transmission oil temperature will exceed the safe temperature (80 ℃).
高溫會(huì)破壞自動(dòng)變速箱油的質(zhì)量和摩擦特性，加大摩擦與磨損，變速箱噪音隨之而來(lái)，同時(shí)，油泥（雜質(zhì)或臟污）也會(huì)在變速箱內(nèi)部產(chǎn)生（例如閥體、控制管路），導(dǎo)致變速箱出現(xiàn)頓挫、沖擊。
High temperature will damage the quality and friction characteristics of the automatic transmission oil, increase friction and wear, and the transmission noise will follow. At the same time, oil sludge (impurities or dirt) will also be generated inside the transmission (such as valve body and control pipeline), resulting in the collapse and impact of the transmission.
如果溫度超過(guò)120℃，橡膠密封材料會(huì)開始變硬老化，密封不嚴(yán)滲漏，比較后導(dǎo)致液壓降。如果溫度更高，變速箱開始打滑，打滑又會(huì)反過(guò)來(lái)使溫度升得更高。（奧迪等車型會(huì)報(bào)警，進(jìn)入變速箱保護(hù)模式）如不及時(shí)解決，變速箱會(huì)報(bào)廢。
If the temperature exceeds 120 ℃, the rubber sealing material will begin to harden and age, and the seal is not tight and leaks, resulting in hydraulic pressure drop after comparison. If the temperature is higher, the transmission begins to slip, which in turn causes the temperature to rise higher. (Audi and other high-end models will alarm and enter the transmission protection mode) if it is not solved in time, the transmission will be scrapped.
濟(jì)南自動(dòng)變速箱維修人員參考一個(gè)定理： 在正常的80℃工作溫度下， 溫度每上升10℃，自動(dòng)變速箱油的使用壽命會(huì)減半。例如，90℃時(shí)，自動(dòng)變速箱油的使用壽命會(huì)降到75000公里。
Jinan automatic transmission maintenance personnel refer to a theorem: under the normal operating temperature of 80 ℃, the service life of automatic transmission oil will be halved for every 10 ℃ rise in temperature. For example, at 90 ℃, the service life of automatic transmission oil will be reduced to 75000 km.
在100℃（這個(gè)溫度很多變速箱都會(huì)經(jīng)常出現(xiàn)）時(shí)，使用壽命只有35000公里左右。120℃時(shí)，則是15000公里。再升高10攝氏度時(shí)，使用壽命只剩下7500公里。超過(guò)146或者148℃時(shí)，自動(dòng)變速箱在1500或者2000公里前會(huì)燒掉。
At 100 ℃ (this temperature often occurs in many gearboxes), the service life is only about 35000 km. At 120 ℃, it is 15000 kilometers. When the temperature rises by another 10 degrees Celsius, the service life is only 7500 kilometers. When the temperature exceeds 146 or 148 ℃, the automatic transmission will burn out before 1500 or 2000 km.
