自动变速箱是相对于手动变速箱而出现的一种能够自动根据汽车车速和发动机转速来进行自动换挡操纵的变速装置，那么您对汽车变速箱了解吗？下面济南自动变速箱维修人员就来为您简单讲解一下这个问题。

The automatic transmission is a kind of transmission device that can automatically shift according to the vehicle speed and engine speed, compared with the manual transmission. Do you know about the automobile transmission? Now Jinan automatic transmission maintenance personnel will explain this problem for you briefly.

1、汽车的变速箱是汽车的主要传动部件，在发动机旋转方向不变情况下，变速箱能利用空挡中断动力传递，以使发动机能够起动、怠速，并便于变速器换挡或进行动力输出，变速箱也能使汽车倒退行驶；

1. The gearbox of an automobile is the main transmission part of the automobile. When the rotation direction of the engine is unchanged, the gearbox can interrupt power transmission by using neutral gear to enable the engine to start and idle, and facilitate the transmission to shift gears or output power. The gearbox can also make the automobile run backward;

2、变速箱分为手动、自动两种，手动变速箱主要由齿轮和轴组成，通过不同的齿轮组合产生变速变矩；而自动变速箱AT是由液力变扭器、行星齿轮和液压操纵系统组成，通过液力传递和齿轮组合的方式来达到变速变矩；

2. Gearboxes are divided into manual and automatic ones. Manual gearboxes are mainly composed of gears and shafts, which generate variable speed and torque through different gear combinations; The automatic transmission AT is composed of hydraulic torque converter, planetary gear and hydraulic control system, which can achieve variable speed and torque through hydraulic transmission and gear combination;

3、汽车变速箱的作用，改变传动比，扩大驱动轮转矩和转速的变化范围，以适应经常变使汽车能倒退行驶；化的行驶条件，同时使发动机在功率较高而油耗较低）的工况下工作；

3. The function of the automobile gearbox is to change the transmission ratio, expand the variation range of the torque and speed of the driving wheel, so as to adapt to the frequent changes and enable the automobile to run backward; The driving conditions are optimized to enable the engine to work under the conditions of high power and low fuel consumption);

4、在发动机旋转方向不变情况下，使汽车能倒退行驶，利用空挡，中断动力传递，以发动机能够起动、变速，并便于变速器换挡或进行动力输出。

4. Under the condition that the rotation direction of the engine remains unchanged, the vehicle can be driven backward. The neutral gear is used to interrupt the power transmission, so that the engine can start and change speed, and it is convenient for the transmission to shift or output power.

汽车变速箱能改变传动比，扩大驱动轮转矩和转速的变化范围，以适应经常变化的行驶条件，同时使发动机在有利（速度较高而油耗较低）的工况下工作；另外在发动机旋转方向不变情况下，使汽车能倒退行驶；变速箱还能利用空挡，中断动力传递，使发动机能够起动、怠速，并便于变速器换挡或进行动力输出。

The automobile gearbox can change the transmission ratio, expand the variation range of the torque and speed of the driving wheel to adapt to the constantly changing driving conditions, and enable the engine to work under favorable conditions (high speed and low fuel consumption); In addition, under the condition that the rotation direction of the engine remains unchanged, the vehicle can be driven backward; The transmission can also use neutral gear to interrupt power transmission, enabling the engine to start and idle, and facilitating transmission shifting or power output.

此外从性能上说自动变速箱的挡位越多，车在行驶过程中也就越平顺，加速性也越好，而且更加省油。除了提供轻松惬意的驾驶感受，自动变速箱也有无法克服的缺陷。所以要定期对其进行保养维修才是。更多注意事项就来我们网站http://www.jnbsx.com咨询吧！

In addition, in terms of performance, the more gears the automatic transmission has, the smoother the car will be when driving, the better the acceleration and the more fuel efficient it will be. In addition to providing a comfortable driving experience, automatic transmissions also have insurmountable defects. Therefore, it is necessary to maintain them regularly.
