The invention discloses an integrated power unit which comprises a motor assembly, a connecting flange, a speed reducer assembly and a rubber coating wheel which are connected in a matched mode, the connecting flange fixedly connected with a vehicle body is arranged between the motor assembly and the speed reducer assembly, and the motor assembly and the speed reducer assembly are both connected with the connecting flange; the first-stage planet carrier is arranged on the end face of the first-stage sun gear, and a first-stage planet gear is installed on the surface of the first-stage planet carrier and meshed with the first-stage sun gear and the inner gear ring. The structure is simple, the motor assembly and the speed reducer assembly are organically combined into a whole through the common connecting flange, on one hand, the axial length is reduced, and on the other hand, the connecting flange bears the load finally, motor driving is not affected, and transmission is stable; and secondly, the first-stage sun gear, the first-stage planet gear, the first-stage planet carrier, the second-stage sun gear, the second-stage planet gear and the second-stage planet carrier share one inner gear ring, the structure is compact, and assembling is convenient.
本发明公开了一种集成式动力单元,包括配合连接的电机组件、连接法兰、减速器组件和包胶轮,电机组件和减速器组件之间设有与车身固定连接的连接法兰,电机组件和减速器组件均与连接法兰连接:减速器组件包括一级太阳轮,设置于一级太阳轮端面的一级行星架,一级行星架的表面安装有一级行星轮,一级行星轮分别与一级太阳轮和内齿圈进行啮合。本发明结构简单,电机组件和减速器组件通过共用连接法兰有机地结合成一体,一是减少了轴向长度,二是由连接法兰最终承受了负载,不影响电机驱动,传动平稳;其次一级太阳轮、一级行星轮、一级行星架、二级太阳轮、二级行星轮、二级行星架均共用一个内齿圈,结构紧密,装配方便。
