要知道质量是否可靠，通过短暂的试驾很难知道。更有效的方法是通过论坛、口碑、质量反馈帖等方式了解。但是变速箱的质量是否可靠，又该如何衡量呢？

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.是否容易过热

1. whether it is easy to overheat

其实对于家用车来说，如果不是经常长时间剧烈驾驶，或者是越野爬各种陡峭陡峭的山路，变速箱过热的问题是很难逼出来的。很长时间。但是，有一个例外。比如一些双离合变速箱。如果散热设计或者换档逻辑有问题，在市区长时间停走，低档切换会导致过热。此时仪表板上会有指示灯。如果你的车更频繁地出现这类提醒，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

对耐用性的直观理解是变速箱中的部件是否耐用。比如离合器、齿轮等部件的扭矩承受能力、抗磨损能力、自清洁自润滑能力、是否会出现异响、漏油等问题。

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.电子系统的稳定性

3. stability of electronic system

在振动和高温的环境下，不仅内部机械部件会受到压力，而且受控电子系统本身的稳定性也会受到考验，包括电磁干扰、高温、振动等，这些都会成为影响因素影响电子系统。因此，我们在日常驾驶中要注意变速箱是否会出现跳档、不换档、绊倒等情况，这可能是电子系统不稳定的先兆。

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，变速箱要完成换档动作，必须有两个过程，一是接受指令，开始换档；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”；执行换档的机械操作过程很快，相当于变速箱的“快速动作”。

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.

济南自动变速器维修人员认为，变速器对燃油经济性的影响主要体现在传动比设置、换挡效率、内耗等方面。燃油经济性通常不能单独讨论变速箱，因为它通常是通过发动机和变速箱的联合匹配来实现的。

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.
