The invention relates to a three-gear AMT speed change system, an electric drive axle and a vehicle adopting the electric drive axle. According to the scheme, the three-gear AMT speed change system comprises an input shaft used for being connected with a drive system and a fourth shaft used for outputting power to the drive axle. The input shaft is in transmission connection with a second shaft and a fifth shaft which are arranged on the two sides of the input shaft respectively, and the second shaft is in transmission connection with a third shaft through a disconnectable connecting mechanism. The third shaft is in transmission connection with a fourth shaft which is collinear with the axis of the input shaft, one end, opposite to the input shaft, of the fourth shaft is provided with a combination gear, the other side of the combination gear of the fourth shaft is adjacently provided with a large gear combination gear, and the large gear combination gear is in transmission connection with a fifth shaft; a gear sleeve and a gear shifting device are arranged on every three adjacent combination teeth, and the gear sleeves are moved through the gear shifting devices, so that the fourth shaft combination teeth and the input shaft combination teeth are connected, the fourth shaft combination teeth and the large gear combination teeth are connected, and all the combination teeth are disconnected. According to the scheme, a high gear, a middle gear and a low gear can be achieved, the number of gear meshing stages is small, and transmission efficiency is high.

    本发明涉及一种三挡AMT变速系统、电驱动桥及采用该电驱动桥的车辆,方案包括用于与驱动系统连接的输入轴,以及用于输出动力到驱动桥的第四轴;输入轴分别传动连接两根在其两侧的第二轴和第五轴,第二轴通过可分断的连接机构与第三轴传动连接;第三轴传动连接与输入轴轴心共线的第四轴,第四轴与输入轴相对的一端分别设置有结合齿,第四轴结合齿的另一侧相邻设置有大齿轮结合齿,大齿轮结合齿与第五轴传动连接;三个相邻的结合齿上设置有齿套和换挡装置,通过换挡装置对齿套的移动,能够实现将第四轴结合齿和输入轴结合齿连接、第四轴结合齿和大齿轮结合齿连接,以及全部断开。方案可以实现高、中、低三个档位,且齿轮啮合级数少,传动效率高。
