變速箱作為第二大汽車核心部件，也是我們的重要保養對象，濟南變速箱油在長期工作中會發生變質揮發，加劇變速箱磨損，接下來我們一起來了解變速箱油的基本常識。根據變速箱的種類不同，變速箱油可分為兩種，一種是手動變速箱油，一種是自動變速箱油。

As the second largest automobile core component, the gearbox is also our important maintenance object. Jinan gearbox oil will deteriorate and volatilize during long-term work, which will aggravate gearbox wear. Next, let's learn the basic knowledge of gearbox oil. According to different types of transmission, transmission oil can be divided into two types, one is manual transmission oil and the other is automatic transmission oil.

變速箱油一般來講，變速箱油有三個作用，個作用是散熱，齒輪之間的相互摩擦做功，勢必會產生大量的熱量，這時候需要潤滑油進行散熱。第二個作用是潤滑，減少齒輪間的磨損，使檔位結合更加的順暢。第三個作用就是清潔，保持排擋系統的清潔，延長傳動裝置的使用壽命。

Generally speaking, the transmission oil has three functions. The first function is to dissipate heat. The mutual friction between gears will certainly generate a large amount of heat. At this time, lubricating oil is required to dissipate heat. The second function is to lubricate, reduce the wear between gears, and make the gear combination more smooth. The third role is to clean, keep the gear system clean and extend the service life of the transmission.

我們何時更換變速箱油要根據車型而定，不同的車型要求不一樣。許多車輛的使用說明書上明確標注了變速箱油要經常進行更換，當然有的車型的使用說明書上也寫了終身免維護，所以要根據實際情況來判斷該不該換。通常情況下，自動變速箱油一般建議4萬公里左右更換一次，車主可以根據自己用車的實際情況來判斷是否進行更換。

When we change the transmission oil depends on the model. Different models have different requirements. The operating instructions of many vehicles clearly indicate that the transmission oil should be replaced frequently. Of course, the operating instructions of some models also indicate that the maintenance is free for life, so it is necessary to judge whether to replace it according to the actual situation. Generally, it is recommended to replace the automatic transmission oil once every 40000 km. The owner can determine whether to replace it according to the actual situation of his own vehicle.

變速箱油如果車掛擋非常順暢，變速箱噪音變化也不大，就可以不用更換。如果車輛換擋時，感到有明顯的生澀或頓挫感，特別是行駛時速超過一百公里以后，變速箱噪音明顯增大，這個時候就要考慮是否更換變速箱油了。

If the transmission oil is very smooth and the noise of the transmission does not change much, it can be replaced. If the vehicle feels obvious astringency or frustration when shifting gears, especially when the speed exceeds 100km / h, the noise of the transmission increases significantly. At this time, it is necessary to consider whether to change the transmission oil.

除此之外，還要經常檢查自動變速箱油液位是否正常。而手動變速箱油由于其變速箱內部結構相對來說比較簡單，且精密度不高，技術相對比較成熟，故手動變速箱油的更換里程可以適當增加。手動變速箱油主要是起潤滑作用，一般的家用車的手動變速箱油是三年或行駛10萬公里左右進行更換一次。

In addition, always check whether the oil level of the automatic transmission is normal. Because the internal structure of the manual transmission oil is relatively simple, the precision is not high, and the technology is relatively mature, the replacement mileage of the manual transmission oil can be appropriately increased. The manual transmission oil is mainly used for lubrication. Generally, the manual transmission oil of household vehicles is replaced once every three years or 100000 kilometers.

變速箱油如果長時間不更換變速箱油，變速箱齒輪的磨損必然會快速加劇，嚴重可造成變速箱提前報廢。所以，我們一定要做好及時更換變速箱油的工作。關注我們http://www.ihudie.cn，了解更多內容！

If the transmission oil is not replaced for a long time, the wear of the transmission gear will inevitably increase rapidly, which may cause the transmission to be scrapped in advance. Therefore, we must do a good job in changing the transmission oil in time. Follow us http://www.ihudie.cn Yes, learn more!
