变速箱油到底是干嘛的呢？-乌什县变扭器异响-就找阿克苏享通

我们知道，自动变速箱是个非常复杂精密的仪器，它的作用是把发动机的动力传递到车辆的行驶系统上。那么变速箱油到底是干嘛的呢？下面来讲讲。

As we know, automatic transmission is a very complex and precise instrument. Its function is to transmit the power of the engine to the driving system of the vehicle. So what is the transmission oil for? Now let's talk about it.

传递动力。

Transmit power.

为了传递动力，变速箱油必须有抗泡性，就是抵抗生成泡沫的能力。在传递动力的过程中，液体因为其不可被压缩而效率很高。但是空气如果混进液体中，通过液力变矩器的不停搅和，就会产生了泡沫，显着降低传递动力的效率。

In order to transmit power, the transmission oil must have anti foaming property, that is, the ability to resist the formation of foam. In the process of transmitting power, liquid is highly efficient because it cannot be compressed. However, if air is mixed into the liquid and stirred continuously by the hydraulic torque converter, foam will be produced, significantly reducing the efficiency of power transmission.

在液力变矩器后面，是变速箱丰富多彩复杂难懂的机械结构。这些机械结构也都是齿轮、摩擦片等组成，和其他机械一样，这些相互接触传递动力的机械结构也需要润滑和散热。

Behind the hydraulic torque converter is the colorful and complicated mechanical structure of the gearbox. These mechanical structures are also composed of gears, friction plates, etc. like other machines, these mechanical structures that contact each other to transmit power also need lubrication and heat dissipation.

润滑和散热。

Lubrication and heat dissipation.

相比于发动机用的机油而言，变速箱油的性能要求更加复杂，因为机油并不承担传递动力的作用。因为变速箱技术的不断发展，为了满足其要求，变速箱油的性能要求也不断提升，相关制造标准也是越来越复杂。

Compared with engine oil, the performance requirements of transmission oil are more complex, because engine oil does not play the role of transmitting power. Because of the continuous development of transmission technology, in order to meet its requirements, the performance requirements of transmission oil are also improving, and the relevant manufacturing standards are becoming more and more complex.

厂商越来越重视变速箱油，也是因为它是确保变速箱总成正常工作的根基要素。因为变速箱性能千差万别，不同型号变速箱的性能诉求也是千差万别。而变速箱油是变速箱执行换挡动作、散发热量和润滑齿轮的载体，自然要承担很多的考验。

Manufacturers pay more and more attention to transmission oil, also because it is the basic element to ensure the normal operation of transmission assembly. Because the performance of gearboxes varies greatly, the performance demands of different models of gearboxes also vary greatly. The transmission oil is the carrier for the transmission to perform the shift action, dissipate heat and lubricate the gears, so it naturally has to bear many tests.

举个例子：自动变速箱要换挡时，都是控制电脑发出信号，而阀体负责执行。阀体的力量源泉则是变速箱油传递过来的液压力。我们知道液压力的大小和液体的粘度息息相关，如果粘度发生巨大变化，那么设计阶段所做的匹配、计算就全部失效了。

For example, when an automatic transmission wants to shift gears, the control computer sends a **, and the valve body is responsible for the implementation. The power source of the valve body is the hydraulic pressure transmitted by the transmission oil. We know that the size of the liquid pressure is closely related to the viscosity of the liquid. If the viscosity changes greatly, the matching and calculation made in the design stage will all fail.

这也是长期使用后的变速箱，都会出现换挡顿挫，而换过阿克苏变速箱油后，情况就会明显改善的原因--换油前，老油的粘度已经无法和新油相比；换油后则恢复到设的理想状态。

This is also the reason why gearboxes that have been used for a long time will have gear shifting setbacks, and the situation will be significantly improved after changing Jinan gearbox oil - before changing the oil, the viscosity of the old oil can no longer be compared with that of the new oil; After oil change, it will return to the ideal state at the time of design.
