換檔是否順暢？
Is the shift smooth?
換檔是否順暢是考慮變速箱質(zhì)量的重要指標(biāo)。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(dāng)于換一組不同速比的齒輪。它會(huì)伴隨著整個(gè)傳動(dòng)系統(tǒng)中許多部件的轉(zhuǎn)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(huì)有離合器，松開離合器后重新接合的過程也會(huì)產(chǎn)生轉(zhuǎn)速變化。這些因素都會(huì)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(shí)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(wěn)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(dòng)作，必須經(jīng)過兩個(gè)過程，一是接受指令開始執(zhí)行換檔；另一種是完成換檔的內(nèi)部機(jī)械作用。這兩個(gè)過程的完成時(shí)間之和就是變速箱完成換檔所花費(fèi)的總時(shí)間?？焖俳邮苤噶钕喈?dāng)于變速箱的“快速響應(yīng)”。
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(zhí)行換檔的機(jī)械過程很快，相當(dāng)于變速箱的“快速動(dòng)作”。在選擇家用車時(shí)，我們很難量化換檔變速箱的時(shí)間。我們只能通過自己的主觀感知來判斷，然后結(jié)合我們?nèi)粘５鸟{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(jì)南自動(dòng)變速箱維修人員認(rèn)為，現(xiàn)在變速箱很多。為了追求平順性和保護(hù)變速箱，故意放慢換擋速度，不僅導(dǎo)致駕駛員踩油門時(shí)動(dòng)力減慢，而且影響駕駛體驗(yàn)。由此產(chǎn)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(píng)價(jià)自動(dòng)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(dāng)然，這取決于你的實(shí)際情況。更多問題將來到我們的網(wǎng)站

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!
