我們知道，自動(dòng)變速箱是個(gè)非常復(fù)雜精密的儀器，它的作用是把發(fā)動(dòng)機(jī)的動(dòng)力傳遞到車輛的行駛系統(tǒng)上。

　　We know that an automatic transmission is a very complex and precise instrument, whose function is to transfer the power of the engine to the vehicle's driving system.

　　在傳遞動(dòng)力的過(guò)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(jiǎn)稱“TC”）

　　In the process of transmitting power, the gearbox has an important component called the "Torque Converter" (TC)

　　我們先來(lái)看一個(gè)例子：一個(gè)風(fēng)扇通上電，對(duì)著另一個(gè)沒(méi)通電的風(fēng)扇猛吹，這個(gè)時(shí)候那個(gè)風(fēng)扇扇葉肯定也會(huì)被吹動(dòng)。而TC，工作原理就是那么簡(jiǎn)單。

　　Let's take an example first: when a fan is powered on and blows fiercely at another fan that is not powered on, the fan blades will definitely be blown as well. And TC, the working principle is so simple.

　　不過(guò)在兩個(gè)風(fēng)扇之間，傳遞動(dòng)力的是空氣，而TC里面?zhèn)鬟f動(dòng)力的就是變速箱油，這就是“液力變矩器”的“液”字所指。

　　However, between the two fans, the power is transmitted by air, while in TC, the power is transmitted by transmission oil, which is what the word "liquid" in "hydraulic torque converter" refers to.

　　變速箱油的個(gè)作用就是傳遞動(dòng)力。但是不僅是液力變矩器需要變速箱油傳遞動(dòng)力哦，變速箱內(nèi)的很多液壓機(jī)械也需要變速箱油來(lái)推動(dòng)，比如負(fù)責(zé)換擋的閥體。

　　The first function of transmission oil is to transmit power. But not only do hydraulic torque converters require transmission oil to transmit power, but many hydraulic machinery inside the gearbox also require transmission oil to drive, such as the valve body responsible for shifting gears.

　　為了傳遞動(dòng)力，變速箱油還必須有抗泡性，就是抵抗生成泡沫的能力。在傳遞動(dòng)力的過(guò)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(guò)液力變矩器的不停攪和，就會(huì)產(chǎn)生了泡沫，顯著降低傳遞動(dòng)力的效率。

　　In order to transmit power, the transmission oil must also have anti foaming property, that is, the ability to resist the generation of foam. In the process of transmitting power, liquids are highly efficient due to their incompressibility. 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(dòng)力的機(jī)械結(jié)構(gòu)也需要潤(rùn)滑和散熱。

　　Behind the hydraulic torque converter, there is a rich and complex mechanical structure of the gearbox that is difficult to understand. These mechanical structures are also composed of gears, friction plates, and other components. Like other machinery, these mechanical structures that transmit power through mutual contact also require lubrication and heat dissipation.

　　這就是變速箱油的第二個(gè)作用：潤(rùn)滑和散熱。

　　This is the second function of transmission oil: lubrication and heat dissipation.

　　相比于發(fā)動(dòng)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(dòng)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(lái)越復(fù)雜

　　Compared to engine oil, the performance requirements of 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 related manufacturing standards are becoming increasingly complex

　　廠商越來(lái)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(wàn)別，不同型號(hào)變速箱的性能訴求也是千差萬(wàn)別。而變速箱油是變速箱執(zhí)行換擋動(dòng)作、散發(fā)熱量和潤(rùn)滑齒輪的載體，自然要承擔(dān)很多的考驗(yàn)。

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

　　舉個(gè)例子：自動(dòng)變速箱要換擋時(shí)，都是控制電腦發(fā)出信號(hào)，而閥體負(fù)責(zé)執(zhí)行。閥體的力量源泉?jiǎng)t是變速箱油傳遞過(guò)來(lái)的液壓力。我們知道液壓力的大小和液體的粘度息息相關(guān)，如果粘度發(fā)生巨大變化，那么設(shè)計(jì)階段所做的匹配、計(jì)算就全部失效了。

　　For example, when an automatic transmission needs to shift gears, the control computer sends a signal, and the valve body is responsible for executing it. The power source of the valve body is the hydraulic pressure transmitted by the transmission oil. We know that the magnitude of liquid pressure is closely related to the viscosity of the liquid. If there is a significant change in viscosity, all matching and calculations made during the design phase will be ineffective.

　　這也是長(zhǎng)期使用后的變速箱，都會(huì)出現(xiàn)換擋頓挫，而換過(guò)變速箱油后，情況就會(huì)明顯改善的原因——換油前，老油的粘度已經(jīng)無(wú)法和新油相比；換油后則恢復(fù)到設(shè)計(jì)時(shí)的理想狀態(tài)。

　　This is also the reason why gearboxes that have been used for a long time will experience shifting jerks, and after changing the transmission oil, the situation will significantly improve - before changing the oil, the viscosity of the old oil can no longer be compared to the new oil; After changing the oil, it will return to the ideal state as designed.

　　在一些極端的案例中，用錯(cuò)了變速箱油，還會(huì)導(dǎo)致變速箱的燒毀。因?yàn)椴粌H僅是粘度經(jīng)過(guò)仔細(xì)計(jì)算、匹配，散熱也是經(jīng)過(guò)精心設(shè)計(jì)的。

　　In some extreme cases, using the wrong transmission oil can also cause the transmission to burn out. Because not only is viscosity carefully calculated and matched, but heat dissipation is also carefully designed.

　　如果變速箱油的承載熱量的能力過(guò)強(qiáng)或過(guò)弱，都會(huì)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。

　　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.
