和手动挡相比，自动变速箱在结构和使用上有很大不同。下面
济南自动变速箱维修厂家就来为您分析自动变速箱的结构特点内容。
Compared with manual transmission, automatic transmission is very different in structure and use. Below, Jinan automatic transmission maintenance factory will analyze the structural characteristics of automatic transmission for you.
手动挡主要通过调节不同齿轮组合来更换挡位，而自动变速箱是通过液力传递和齿轮组合的方式来达到变速的目的。
The manual gear mainly changes gears by adjusting different gear combinations, while the automatic transmission achieves the purpose of speed change through hydraulic transmission and gear combination.
其中液力变扭器是自动变速箱具特点的部件，它由泵轮、涡轮和导轮等构件组成，泵轮和涡轮是一对工作组合，泵轮通过液体带动涡轮旋转，而泵轮和涡轮之间的导轮通过反作用力使泵轮和涡轮之间实现转速差并实现变速变矩功能，对驾驶者来说，您只需要以不同力度踩住踏板，变速箱就可以自动进行挡位升降。
Among them, the hydraulic torque converter is a characteristic component of the automatic transmission. It is composed of components such as the pump wheel, turbine and guide wheel. The pump wheel and turbine are a pair of working combinations. The pump wheel drives the turbine to rotate through the liquid, and the guide wheel between the pump wheel and the turbine realizes the speed difference between the pump wheel and the turbine through the reaction force and realizes the variable speed torque function. For the driver, you only need to step on the pedal with different strength, The transmission can automatically move the gear up and down.
由于液力变矩器自动变速变矩范围不够大，因此在涡轮后面再串联几排行星齿轮提率，液压操纵系统会随发动机工作变化自行操纵行星齿轮，从而实现自动变速变矩。为了满足行驶过程中的多种需要(如泊车、倒车)等，自动变速箱还设有一些手动拨杆位置，像P挡(停泊)、R挡(后挡)、N挡(空档)、D挡(前进)等。
Since the automatic transmission and torque conversion range of the hydraulic torque converter is not large enough, several rows of planetary gears are connected in series behind the turbine to improve efficiency. The hydraulic control system will control the planetary gears according to the working changes of the engine, so as to realize automatic transmission and torque conversion. In order to meet various needs during driving (such as parking and reversing), the automatic transmission is also equipped with some manual paddle positions, such as P gear (parking), R gear (rear gear), n gear (neutral), D gear (forward), etc.
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。自动变速箱的动力响应不够直接，这使它在“驾驶乐趣”方面稍显不足。此外，由于采用液力传动，这使自动挡变速箱传递的动力有所损失。
In terms of performance, the more gears the automatic transmission has, the smoother the car will be in the driving process, the better the acceleration and the more fuel-efficient it will be. In addition to providing a comfortable driving experience, the automatic transmission also has insurmountable defects. The power response of the automatic transmission is not direct enough, which makes it slightly insufficient in "driving pleasure". In addition, due to the hydraulic transmission, the power transmitted by the automatic transmission is lost.
自动变速器的保养方法：
Maintenance method of automatic transmission:
自动变速器需按照规定添加变速箱油。切不可因为贪图便宜或方便，添加手动挡变速器机油，不然将会对离合器和制动器产生严重的烧蚀。在正规的自动变速器油里配置了适量的摩擦改良剂，它可以保证离合器与制动器能够正常地工作。摩擦改良剂的数量是根据自动变速器能承受的负荷改变而改变的，并不存在一个恒定的数值。
The automatic transmission shall be filled with transmission oil as required. Do not add manual transmission oil for the sake of cheapness or convenience, otherwise it will cause serious erosion to the clutch and brake. A proper amount of friction improver is provided in the normal automatic transmission oil to ensure that the clutch and brake can work normally. The amount of friction improver varies according to the load that the automatic transmission can bear, and there is no constant value.
In addition to adding according to the regulations, it is also necessary to add according to the model of transmission oil, otherwise the clutch will slip and the hot car will jump. For more information, please visit our website http://www.jnbsx.com Consultation and understanding.
