要知道質量是否可靠，通過短暫的試駕很難知道。更有效的方法是通過論壇、口碑、質量反饋帖等方式了解。但是變速箱的質量是否可靠，又該如何衡量呢？

It is difficult to know whether the quality is reliable after a short test drive. A more effective way is to understand through forums, word of mouth, quality feedback posts, etc. But whether the quality of the gearbox is reliable, and how to measure it?

1.是否容易過熱

1. whether it is easy to overheat

其實對于家用車來說，如果不是經常長時間劇烈駕駛，或者是越野爬各種陡峭陡峭的山路，變速箱過熱的問題是很難逼出來的。很長時間。但是，有一個例外。比如一些雙離合變速箱。如果散熱設計或者換檔邏輯有問題，在市區長時間停走，低檔切換會導致過熱。此時儀表板上會有指示燈。如果你的車更頻繁地出現這類提醒，你就要注意了。

In fact, for household vehicles, if they don't often drive violently for a long time, or climb all kinds of steep mountain roads off-road, the problem of overheating of the gearbox is very difficult to force out. for ages. However, there is one exception. For example, some double clutch gearboxes. If there is a problem with the heat dissipation design or shift logic, if you stop in the urban area for a long time, low gear switching will lead to overheating. There will be an indicator on the instrument panel. If your car has this kind of reminder more frequently, you should pay attention to it.

2、耐不耐用

2. Durable or not

對耐用性的直觀理解是變速箱中的部件是否耐用。比如離合器、齒輪等部件的扭矩承受能力、抗磨損能力、自清潔自潤滑能力、是否會出現異響、漏油等問題。

The intuitive understanding of durability is whether the components in the transmission are durable. For example, the torque bearing capacity, wear resistance, self-cleaning and self-lubricating capacity of clutch, gear and other components, and whether there will be abnormal noise, oil leakage and other problems.

3.電子系統的穩定性

3. stability of electronic system

在振動和高溫的環境下，不僅內部機械部件會受到壓力，而且受控電子系統本身的穩定性也會受到考驗，包括電磁干擾、高溫、振動等，這些都會成為影響因素影響電子系統。因此，我們在日常駕駛中要注意變速箱是否會出現跳檔、不換檔、絆倒等情況，這可能是電子系統不穩定的先兆。

In the environment of vibration and high temperature, not only the internal mechanical components will be under pressure, but also the stability of the controlled electronic system itself will be tested, including electromagnetic interference, high temperature, vibration, etc., which will become the influencing factors affecting the electronic system. Therefore, during daily driving, we should pay attention to whether the transmission will jump, do not shift, trip, etc., which may be a precursor to the instability of the electronic system.

另外，變速箱要完成換檔動作，必須有兩個過程，一是接受指令，開始換檔；另一種是完成換檔的內部機械作用。這兩個過程的完成時間之和就是變速箱完成換檔所花費的總時間。快速接受指令，相當于變速箱的“快速響應”；執行換檔的機械操作過程很快，相當于變速箱的“快速動作”。

In addition, there must be two processes for the gearbox to complete the shift action. One is to accept the command and start the shift; The other is to complete the internal mechanical function of gear shifting. The sum of the completion time of these two processes is the total time spent by the transmission to complete the shift. Quick command receiving, equivalent to "quick response" of the transmission; The mechanical operation process of gear shifting is very fast, which is equivalent to the "quick action" of the transmission.

濟南自動變速器維修人員認為，變速器對燃油經濟性的影響主要體現在傳動比設置、換擋效率、內耗等方面。燃油經濟性通常不能單獨討論變速箱，因為它通常是通過發動機和變速箱的聯合匹配來實現的。

Jinan automatic transmission maintenance personnel believe that the impact of transmission on fuel economy is mainly reflected in the transmission ratio setting, shift efficiency, internal friction and so on. Fuel economy can not be discussed separately because it is usually achieved through the joint matching of engine and transmission.

綜上所述，自動變速器需要在各方面都有出色的表現，才能成為好的自動變速器，為我們提供順暢的駕駛體驗。以上就是本文的內容。看完這篇文章，希望對你有所幫助。我們的網站上有很多相關內容的詳細說明。如果您想了解更多，請關注我們的網站www.mmolords.cn。
