The invention discloses a pure electric power assembly integrated with a double-intermediate-shaft speed reducer, and belongs to the technical field of automobile power assemblys.The pure electric power assembly comprises a high-speed motor and a multi-gear AMT transmission and further comprises a speed reducer connecting the high-speed motor and the multi-gear AMT transmission, the speed reducer comprises a shell, and an input shaft and an output shaft which are coaxially arranged are arranged in the shell; the input shaft is connected with a high-speed motor, the output shaft is connected with a multi-gear AMT transmission, intermediate shafts parallel to the input shaft are arranged in the shell on the two sides of the input shaft respectively, the input shaft is provided with a first-stage speed reduction driving gear, the intermediate shafts are provided with first-stage speed reduction driven gears meshed with the first-stage speed reduction driving gear, and the output shaft is provided with a second-stage speed reduction driven gear. The middle shaft is provided with a second-stage speed reduction driving gear meshed with the second-stage speed reduction driven gear. The input shaft and the output shaft of the speed reducer are coaxially arranged, the overall dimension of an assembly can be reduced, arrangement of the assembly is facilitated, and the structural radial force of the two intermediate shafts counteracts mutually, so that transmission of the speed reducer is more stable.

    本发明公开了一种集成双中间轴减速器的纯电动力总成,属于汽车动力总成技术领域,本发明包括高速电机、多挡AMT变速器,还包括将高速电机、多挡AMT变速器连接的减速器,减速器包括壳体,壳体内设有同轴布置的输入轴、输出轴,输入轴连接高速电机,输出轴连接多挡AMT变速器,输入轴两侧的壳体内分别设有与输入轴平行的中间轴,输入轴设有一级减速主动齿轮,中间轴设有与一级减速主动齿轮啮合的一级减速从动齿轮,输出轴设有二级减速从动齿轮,中间轴设有与二级减速从动齿轮啮合的二级减速主动齿轮。本发明中减速器的输入轴与输出轴同轴布置,可以减小总成外形尺寸,方便总成布置,且两个中间轴的结构径向力互相抵消,使得减速器传动更加平稳。
