自动变速器(简称DCT)是基于手动变速箱发展而来的。它的工作原理是通过集成电子和液压元件的机械电子模块来实现换挡和离合操作,而不是通过离合器踏板。与手动变速箱不同,DCT中的两幅离合器与二根输入轴相连。
Automatic transmission (DCT) is developed based on manual transmission. Its working principle is to achieve gear shifting and clutch operation through a mechanical electronic module that integrates electronic and hydraulic components, rather than through the clutch pedal. Unlike manual transmissions, the two clutches in DCT are connected to two input shafts.
驾驶员可以选择手动换挡或将变速杆处于全自动D挡(舒适型,在发动机低速运行时换挡)或S挡(任务型,在发动机高速运行时换挡)。在这种模式下,换挡通常由挡位和离合执行器实现。两幅离合器各自与不同的输入轴相连。例如,离合器1通过实心轴与挡位1、3、5相连,离合器2则通过空心轴与挡位2、4、6和倒挡相连。这种变速箱形式有两组离合器,一个控制1、3、5挡,另一个控制2、4、6挡。使用一挡的时候,二挡已经准备好,因此换挡时间大大缩短,没有延时。
The driver can choose to manually shift gears or shift the gear lever to fully automatic D gear (Comfort type, shifting when the engine is running at low speeds) or S gear (Task type, shifting when the engine is running at high speeds). In this mode, shifting is usually achieved by gear and clutch actuators. The two clutches are connected to different input shafts. For example, clutch 1 is connected to gears 1, 3, and 5 through a solid shaft, while clutch 2 is connected to gears 2, 4, 6, and reverse through a hollow shaft. This type of gearbox has two sets of clutches, one controlling 1st, 3rd, and 5th gears, and the other controlling 2nd, 4th, and 6th gears. When using first gear, second gear is already ready, so the shifting time is greatly reduced without any delay.
总的来说,自动变速器的工作原理是通过集成电子和液压元件的机械电子模块来实现换挡和离合操作,与手动变速箱不同,驾驶员可以选择不同的挡位模式,以适应不同的驾驶需求。
Overall, the working principle of an automatic transmission is to achieve shifting and clutch operations through a mechanical electronic module that integrates electronic and hydraulic components. Unlike manual transmissions, drivers can choose different gear modes to adapt to different driving needs.
