換檔是否順暢？

Is the shift smooth?

換檔是否順暢是考慮變速箱質量的重要指標。為什么有些變速箱換檔不均勻？一方面，除CVT變速箱外，其他類型的變速箱都是由多組不同速比的齒輪組成的齒輪。換檔的過程相當于換一組不同速比的齒輪。它會伴隨著整個傳動系統中許多部件的轉速突然變化。

Whether the gear shift is smooth is an important indicator to consider the quality of the transmission. Why do some transmissions shift unevenly? On the one hand, except CVT gearbox, other types of gearboxes are composed of multiple groups of gears with different speed ratios. The process of shifting gears is equivalent to changing a group of gears with different speed ratios. It will be accompanied by sudden changes in the speed of many components in the whole transmission system.

此外，很多變速箱都會有離合器，松開離合器后重新接合的過程也會產生轉速變化。這些因素都會造成一定的力沖擊，使駕駛者感到不舒服，稱為挫折。

In addition, many transmissions have clutches, and the process of releasing the clutch and re engaging will also produce speed changes. These factors will cause certain force impact and make the driver feel uncomfortable, which is called frustration.

一般來說，這種挫折在低速行駛中很常見，所以在試車的時候，可以選擇一些低速路段，低速行駛，或者走走停停，試試看能不能感覺到來自車子的影響比較明顯，沒有的話，變速箱還是比較平穩的。

Generally speaking, this kind of frustration is very common in low-speed driving, so when testing, you can choose some low-speed sections, drive at low speed, or walk and stop to see if you can feel the obvious impact from the car. If not, the gearbox is relatively stable.

變速箱換檔速度

Transmission shift speed

變速箱要完成換檔動作，必須經過兩個過程，一是接受指令開始執行換檔；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”。

To complete the shift action, the gearbox must go through two processes: one is to accept the command to 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 acceptance is equivalent to "quick response" of the transmission.

執行換檔的機械過程很快，相當于變速箱的“快速動作”。在選擇家用車時，我們很難量化換檔變速箱的時間。我們只能通過自己的主觀感知來判斷，然后結合我們日常的駕駛需求來判斷是否可以接受。

The mechanical process of gear shifting is very fast, which is equivalent to the "quick action" of the transmission. When choosing a family car, it is difficult to quantify the time to shift the transmission. We can only judge by our subjective perception, and then judge whether it is acceptable in combination with our daily driving needs.

濟南自動變速箱維修人員認為，現在變速箱很多。為了追求平順性和保護變速箱，故意放慢換擋速度，不僅導致駕駛員踩油門時動力減慢，而且影響駕駛體驗。由此產生的車輛燃料消耗的增加是值得注意的。

Jinan automatic transmission maintenance personnel believe that there are many transmissions now. In order to pursue smoothness and protect the gearbox, deliberately slow down the shift speed, which not only causes the driver to slow down when stepping on the accelerator, but also affects the driving experience. The resulting increase in vehicle fuel consumption is noteworthy.

如果從換擋的角度來評價自動變速箱的好壞，我們將從換擋是否平順和變速箱的換擋速度來說明問題。你可以參考一下。當然，這取決于你的實際情況。更多問題將來到我們的網站www.gxrbbs.com留言咨詢！

If we evaluate the quality of the automatic transmission from the perspective of shifting, we will explain the problem from the smoothness of shifting and the shifting speed of the transmission. You can refer to it. Of course, it depends on your actual situation. More questions will come to our website www.jnbsx Com message consultation!
