换档是否顺畅？

Is the shift smooth?

换档是否顺畅是考虑变速箱质量的重要指标。为什么有些变速箱换档不均匀？一方面，除CVT变速箱外，其他类型的变速箱都是由多组不同速比的齿轮组成的齿轮。换档的过程相当于换一组不同速比的齿轮。它会伴随着整个传动系统中许多部件的转速突然变化。

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，很多变速箱都会有离合器，松开离合器后重新接合的过程也会产生转速变化。这些因素都会造成一定的力冲击，使驾驶者感到不舒服，称为挫折。

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.

一般来说，这种挫折在低速行驶中很常见，所以在试车的时候，可以选择一些低速路段，低速行驶，或者走走停停，试试看能不能感觉到来自车子的影响比较明显，没有的话，变速箱还是比较平稳的。

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.

变速箱换档速度

Transmission shift speed

变速箱要完成换档动作，必须经过两个过程，一是接受指令开始执行换档；另一种是完成换档的内部机械作用。这两个过程的完成时间之和就是变速箱完成换档所花费的总时间。快速接受指令相当于变速箱的“快速响应”。

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.

执行换档的机械过程很快，相当于变速箱的“快速动作”。在选择家用车时，我们很难量化换档变速箱的时间。我们只能通过自己的主观感知来判断，然后结合我们日常的驾驶需求来判断是否可以接受。

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.

济南自动变速箱维修人员认为，现在变速箱很多。为了追求平顺性和保护变速箱，故意放慢换挡速度，不仅导致驾驶员踩油门时动力减慢，而且影响驾驶体验。由此产生的车辆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.

如果从换挡的角度来评价自动变速箱的好坏，我们将从换挡是否平顺和变速箱的换挡速度来说明问题。你可以参考一下。当然，这取决于你的实际情况。更多问题将来到我们的网站www.jnbsx.com留言咨询！

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!
