The invention relates to the electric vehicle driving technology, and particularly discloses an integrated axle assembly which comprises a motor, a speed reducer connected with the motor and a drivingaxle connected with the speed reducer. The speed reducer comprises a first-stage speed reduction gear assembly and a second-stage speed reduction gear assembly; the primary reduction gear assembly comprises a gear ring, a first planet gear, a sun gear and a second planet gear, the sun gear is externally meshed with the first planet gear and the second planet gear, and the gear ring is internallymeshed with the first planet gear and the second planet gear; the second-stage speed reduction gear assembly comprises a secondary speed reducer gear and a speed reducer output shaft; the gear ring isin gear connection with the second-stage speed reducer so as to be suitable for connecting the first-stage speed reduction gear assembly with the second-stage speed reduction gear assembly. In addition, the invention further discloses a vehicle comprising the integrated axle assembly. According to the integrated axle assembly, the distance between the motor and the drive axle can be reduced, thestructure is simpler, and the performance is more reliable.

    本发明涉及电动车驱动技术,具体公开了一种集成桥总成,包括电机、与电机连接的减速器和与减速器连接的驱动桥;减速器包括一级减速齿轮组件和二级减速齿轮组件;一级减速齿轮组件包括齿圈、第一行星轮、太阳轮和第二行星轮,太阳轮分别与第一行星轮和第二行星轮外啮合,齿圈分别与第一行星轮和第二行星轮内啮合;二级减速齿轮组件包括二级减速器齿轮和减速器输出轴;齿圈与二级减速器齿轮连接,以适于将一级减速齿轮组件和二级减速齿轮组件连接。此外,本发明还公开了包括该集成桥总成的车辆。本发明的集成桥总成能够减小电机与驱动桥的轴间距离,结构更加简单,性能更加可靠。
