The invention relates to an integrated multi-gear single-shifting gear shaft electric drive assembly which comprises a shifting gear shaft, the shifting gear shaft is a single-shifting gear shaft, the shifting gear shaft is in meshing transmission with a primary reduction gear shaft and an output shaft assembly to form a shifting gear shaft system, and power switching among different working conditions is achieved. A first sliding meshing sleeve is arranged between the primary reduction gear shaft and the gear shifting gear shaft, a second sliding meshing sleeve is arranged between the output shaft assembly and the gearbox shell, and the first sliding meshing sleeve and the second sliding meshing sleeve are in meshing transmission with the power joint sleeve through left-right movement, so that power switching among different working conditions is achieved. By adopting the shifting gear shaft system of the single shifting gear shaft, the power performance of the electric driving system is improved, meanwhile, the energy consumption of the driving system and the structural complexity of a product are remarkably reduced, and the manufacturing cost of the product is greatly reduced.

    本发明涉及一种集成式多挡位单换挡齿轮轴电驱动总成,包括换挡齿轮轴,换挡齿轮轴为单换挡齿轮轴,换挡齿轮轴分别与一级减速齿轮轴及输出轴组件啮合传动,构成换挡齿轮轴系,实现不同工况之间的动力切换,一级减速齿轮轴与换挡齿轮轴之间设有第一滑动啮合套,输出轴组件与变速箱壳体之间设有第二滑动啮合套,第一滑动啮合套与第二滑动啮合套通过左右移动,分别与动力接合套啮合传动,实现不同工况之间的动力切换。本发明通过采用单换挡齿轮轴的换挡齿轮轴系,在实现电驱动系统动力性能提升的同时,驱动系统能耗以及产品的结构复杂程度均得到显著降低,产品的制造成本大幅下降。
