According to the multi-gear coaxial electric drive axle structure, all arrangements are coaxially arranged, the size is small, the structure is compact, the whole vehicle arrangement is simple, an electric drive axle power assembly is reasonable in mass distribution, the theoretical mass center is coaxial with the axle housing axis, and the stress and vibration conditions are greatly improved. The differential mechanism assembly comprises a differential mechanism, an A-side half shaft and a B-side half shaft; the A-side half shaft and the B-side half shaft are fixedly connected with the differential mechanism respectively, and power is transmitted to the outside in a differential mode. Each two-gear power assembly comprises a driving motor assembly, a front planet row assembly, a rear planet row assembly and a gear shifting planet row assembly which are coaxially arranged; one group of two-gear power components is located at the corresponding position of the A-side half shaft to form an A-side power component, and the other group of two-gear power components is located at the corresponding position of the B-side half shaft to form a B-side power component.

    本发明提供了一种多挡同轴电驱桥结构,其所有布置均同轴布置,体积小、结构紧凑、整车布置简单,电驱桥动力总成质量分布合理,理论质心与桥壳轴线同轴,极大地改善了受力与振动状况。其包括:差速器组件,其包括差速器、A侧半轴、B侧半轴;所述A侧半轴、B侧半轴分别与差速器固连在一起,差速传递动力至外界;以及两组二挡动力组件,每组所述二挡动力组件包括同轴布置的驱动电机组件、前行星排组件、后行星排组件、换挡行星排组件;一组二挡动力组件位于所述A侧半轴的对应位置形成A侧动力组件,另一组二挡动力组件位于所述B侧半轴的对应位置形成B侧动力组件。
