不同年份不同車型可能使用多款自動變速箱，同品牌不同型號的變速箱油能混用嗎？其次，盡管整車品牌眾多，但生產(chǎn)自動變速箱的企業(yè)倒不多，用量比較大的也就采埃孚、愛信、通用、奔馳等幾家廠商。那么不同廠家的自動變速箱能使用相同的變速箱油嗎？或者同一廠家的自動變速器使用同一種變速箱油嗎？

　　Multiple automatic transmissions may be used in different years and models. Can different types of transmission fluids from the same brand be mixed? Secondly, although there are many vehicle brands, there are not many companies that produce automatic transmissions, and only a few manufacturers such as ZF, Aisin, General Motors, and Mercedes Benz use them in large quantities. Can automatic transmissions from different manufacturers use the same transmission fluid? Or do automatic transmissions from the same manufacturer use the same type of transmission fluid?

　　相應(yīng)的另一些油品生產(chǎn)企業(yè)，推出許多種的“替代油品”、“升級油品”或“通用油品”。這些油品真的能適用于各種不同的變速箱嗎？

　　Correspondingly, other oil production enterprises have launched many types of "alternative oil products", "upgraded oil products" or "universal oil products". Can these oils really be applied to various types of transmissions?

　　類似于以上的問題事實(shí)上還有很多。說了這么多，變速箱油到底是干嘛的呢？我們知道，自動變速箱是個(gè)非常復(fù)雜的儀器，它的作用是把發(fā)動機(jī)的動力傳遞到車輛的行駛系統(tǒng)上。在傳遞動力的過程中，變速箱有個(gè)很重要的部件，叫“液力變矩器”（Torque Converter，下文簡稱“TC”）。

　　There are actually many similar issues as mentioned above. After all that has been said, what exactly is gearbox oil for? We know that an automatic transmission is a very complex instrument that transfers the power of the engine to the vehicle's driving system. In the process of transmitting power, the gearbox has an important component called the "Torque Converter" (TC).

　　變速箱油的其中一個(gè)作用就是傳遞動力。但是不僅是液力變矩器需要變速箱油傳遞動力哦，變速箱內(nèi)的很多液壓機(jī)械也需要變速箱油來推動，比如負(fù)責(zé)換擋的閥體。為了傳遞動力，變速箱油還有抗泡性，就是抵抗生成泡沫的能力。在傳遞動力的過程中，液體因?yàn)槠洳豢杀粔嚎s而效率很高。但是空氣如果混進(jìn)液體中，通過液力變矩器的不停攪和，就會產(chǎn)生了泡沫，顯著降低傳遞動力的效率。

　　One of the functions of gearbox oil is to transmit power. But not only does the hydraulic torque converter require gearbox oil to transmit power, but many hydraulic machinery inside the gearbox also require gearbox oil to drive, such as the valve body responsible for shifting gears. In order to transmit power, the transmission oil also has anti foaming property, which is the ability to resist the generation of foam. In the process of transmitting power, liquids are highly efficient because they cannot be compressed. However, if air is mixed into the liquid and continuously stirred by the hydraulic torque converter, foam will be produced, which will significantly reduce the efficiency of power transmission.

　　在液力變矩器后面，是變速箱豐富多彩復(fù)雜難懂的機(jī)械結(jié)構(gòu)。這些機(jī)械結(jié)構(gòu)也都是齒輪、摩擦片等組成，和其他機(jī)械一樣，這些相互接觸傳遞動力的機(jī)械結(jié)構(gòu)也需要潤滑和散熱。這就是變速箱油的另一個(gè)作用：潤滑和散熱。

　　Behind the hydraulic torque converter is the diverse, complex, and difficult to understand mechanical structure of the gearbox. These mechanical structures are also composed of gears, friction plates, etc. Like other machines, these mechanical structures that come into contact with each other to transmit power also require lubrication and heat dissipation. This is another function of gearbox oil: lubrication and heat dissipation.

　　相比于發(fā)動機(jī)用的機(jī)油而言，變速箱油的性能要求更加復(fù)雜，因?yàn)闄C(jī)油并不承擔(dān)傳遞動力的作用。因?yàn)樽兯傧浼夹g(shù)的不斷發(fā)展，為了滿足其要求，變速箱油的性能要求也不斷提升，相關(guān)制造標(biāo)準(zhǔn)也是越來越復(fù)雜。

　　Compared to engine oil, the performance requirements for transmission oil are more complex because oil does not play a role in transmitting power. Due to the continuous development of transmission technology, in order to meet its requirements, the performance requirements of transmission oil are also constantly improving, and the relevant manufacturing standards are becoming increasingly complex.

　　廠商越來越重視變速箱油，也是因?yàn)樗谴_保變速箱總成正常工作的根基要素。因?yàn)樽兯傧湫阅芮Р钊f別，不同型號變速箱的性能訴求也是千差萬別。而變速箱油是變速箱執(zhí)行換擋動作、散發(fā)熱量和潤滑齒輪的載體，自然要承擔(dān)很多的考驗(yàn)。

　　Manufacturers are increasingly valuing gearbox oil because it is a fundamental element in ensuring the normal operation of the gearbox assembly. Because the performance of gearboxes varies greatly, the performance requirements of different models of gearboxes are also vastly different. And gearbox oil is the carrier for the gearbox to perform shifting actions, dissipate heat, and lubricate gears, naturally bearing many tests.

　　在一些別的案例中，用錯(cuò)了變速箱油，還會導(dǎo)致變速箱的燒毀。因?yàn)椴粌H僅是粘度經(jīng)過仔細(xì)計(jì)算、匹配，散熱也是經(jīng)過精心設(shè)計(jì)的。如果變速箱油的承載熱量的能力過強(qiáng)或過弱，都會導(dǎo)致散熱機(jī)構(gòu)效能降低，從而影響散熱，導(dǎo)致變速箱燒毀。

　　In some other cases, using the wrong transmission oil can also cause the transmission to burn out. Because not only the viscosity is carefully calculated and matched, but also the heat dissipation is carefully designed. If the heat carrying capacity of the transmission oil is too strong or too weak, it will lead to a decrease in the efficiency of the heat dissipation mechanism, thereby affecting heat dissipation and causing the transmission to burn out.
