談到變速箱維修，就要說到變速箱更換油的問題，一種是我們常見的重力置換法，另一種則是利用自動(dòng)循環(huán)機(jī)的循環(huán)替換法，那么這兩種更換自動(dòng)變速箱油方法本質(zhì)上有何區(qū)別呢？下面來解析下。
When it comes to gearbox maintenance, we need to talk about the problem of gearbox oil replacement. One is our common gravity replacement method, and the other is the circulation replacement method of automatic circulator. What is the difference between the two methods of automatic gearbox oil replacement in essence? Let's analyze it.
重力置換法
Gravity displacement method
相信更換過自動(dòng)變速箱油的車主都知道，重力更換法留下的舊變速箱比較多。至于為什么會(huì)有更多的殘留物，這與自動(dòng)變速器內(nèi)部復(fù)雜的設(shè)計(jì)結(jié)構(gòu)直接相關(guān)。變速箱中應(yīng)至少包含6至8升自動(dòng)變速箱油。其中，閥體模塊的液力偶合器約占總油量的50%，有些自動(dòng)變速器油底殼設(shè)計(jì)成形狀的原因也會(huì)占用一部分變速器油液。
I believe the owners who have changed the automatic transmission oil know that there are more old transmissions left by the gravity replacement method. As for why there are more residues, this is directly related to the complex design structure inside the automatic transmission. The transmission should contain at least 6 to 8 litres of automatic transmission oil. Among them, the hydraulic coupling of the valve body module accounts for about 50% of the total oil volume. Some automatic transmission oil pans are designed to take up part of the transmission oil.
當(dāng)然，在一些自動(dòng)變速器中，即使拆下油底殼，也看不到變速器濾芯。這就是所謂的不可更換的傳動(dòng)濾芯。這種傳動(dòng)濾芯不是不可能更換的。更換變速箱總成需要拆開濾芯，所以拆開變速箱總成只是為了更換濾芯是弊大于利的。
Of course, in some automatic transmissions, even if the oil pan is removed, the transmission filter element cannot be seen. This is the so-called non replaceable transmission filter element. This transmission filter element is not impossible to replace. The filter element needs to be disassembled to replace the transmission assembly, so it is more harmful than beneficial to disassemble the transmission assembly just to replace the filter element.
重力交換法的優(yōu)點(diǎn)：操作簡(jiǎn)單，油耗少，相對(duì)經(jīng)濟(jì)，而且這種重力交換法正好可以降低高公里自動(dòng)變速器換油的風(fēng)險(xiǎn)。
Advantages of gravity exchange method: simple operation, low fuel consumption and relatively economic, and this gravity exchange method can just reduce the risk of oil change of high kilometer automatic transmission.
提醒大家：重力更換方式二次污染嚴(yán)重，但請(qǐng)相應(yīng)縮短下次更換變速箱油的時(shí)間和公里數(shù)。這樣做的目的是讓您的變速箱更好地工作環(huán)境。
Remind you: the gravity replacement method has serious secondary pollution, but please shorten the time and kilometers for the next replacement of transmission oil accordingly. The purpose of this is to make your gearbox work better.
循環(huán)替換法
Cyclic substitution method
濟(jì)南變速箱維修廠家認(rèn)為循環(huán)置換法比重力置換法復(fù)雜。復(fù)雜的步驟是循環(huán)置換法和重力置換法的結(jié)合。除了循環(huán)器的等量交換外，一些自動(dòng)變速器在更換機(jī)油時(shí)，不僅要靠重力先放油，還需要拆下油底殼，更換變速器濾芯，更換得更徹底、更干凈。同時(shí)，更換變速箱油前、中、后的每一步都不能出錯(cuò)。簡(jiǎn)單來說，更換工藝要求比較高。
The manufacturer thinks that the gravity replacement method is more complex than the gravity replacement method. The complex step is the combination of cyclic displacement method and gravity displacement method. In addition to the equivalent exchange of the circulator, when changing the oil of some automatic transmissions, it is not only necessary to drain the oil by gravity, but also need to remove the oil pan and replace the transmission filter element to make the replacement more thorough and clean. At the same time, make no mistake in every step before, during and after changing the transmission oil. In short, the replacement process requires relatively high requirements.
循環(huán)更換方法是設(shè)備連接后，車輛起火，自動(dòng)變速箱對(duì)循環(huán)機(jī)建立一定的壓力，使變速箱與循環(huán)機(jī)連接并循環(huán)。更多的舊油從車身模塊和液力耦合器中釋放出來。一般來說，正常的自動(dòng)變速箱循環(huán)更換油在十升左右。更換變速箱油的更終清潔度取決于變速箱的公里數(shù)和使用多少油。
The cycle replacement method is that after the equipment is connected, the vehicle catches fire, and the automatic transmission establishes a certain pressure on the circulator to connect and cycle the transmission with the circulator. More old oil is released from the body module and hydraulic coupler. Generally speaking, the normal automatic transmission cycle replacement oil is about ten liters. The final cleanliness of changing transmission oil depends on the mileage of the transmission and how much oil is used.
循環(huán)更換方式的優(yōu)點(diǎn)：舊變速箱油殘留量小，新油二次污染不嚴(yán)重，變速箱可以始終在良好的工作環(huán)境中工作。
Advantages of circulating replacement method: the residual amount of old transmission oil is small, the secondary pollution of new oil is not serious, and the transmission can always work in a good working environment.
此外提醒您，不同類型的變速箱油它不能通用的，大部分自動(dòng)變速箱都有自己專屬的變速箱油，手動(dòng)變速箱油還有粘度和等級(jí)之分，因此根據(jù)實(shí)際情況來選擇油并換油，更多相關(guān)內(nèi)容就來關(guān)注我們的網(wǎng)站

In addition, I would like to remind you that different types of transmission oil cannot be used in general. Most automatic transmissions have their own transmission oil, and manual transmission oil can also be divided into viscosity and grade. Therefore, select and change the oil according to the actual situation. For more relevant contents, please pay attention to our website fdwhkj.cn Check out the information. Www. 68mn!
