The integrated shaft electric drive assembly structure comprises a shell, a rotating shaft arranged in the shell, a stator and rotor mechanism and a speed reducing mechanism, the stator and rotor mechanism and the speed reducing mechanism are coaxially connected to the rotating shaft, and the rotating shaft comprises a motor shaft section coaxially connected with the stator and rotor mechanism and a speed reducer shaft section coaxially connected with the speed reducing mechanism; the rotating shaft is coaxially connected with a plurality of bearings at intervals in the axial direction of the rotating shaft. And an integrated shaft structure integrating the motor shaft and the speed reducer shaft is adopted, so that the number of parts is reduced, and the overall structure is simplified. Compared with a traditional split type shaft structure, additional connecting parts and complex assembling procedures are not needed, the production cost is reduced, the production efficiency is improved, the NVH performance of a vehicle is optimized, and the size of an electric drive assembly is reduced.

    本发明公开了一种一体轴电驱动总成结构及车辆,包括壳体、设置于壳体内部的转轴、以及同轴连接于转轴上的定转子机构和减速机构,所述转轴包括与所述定转子机构同轴连接的电机轴段和与所述减速机构同轴连接的减速器轴段,所述转轴沿其轴向间隔同轴连接有多个轴承。采用电机轴与减速器轴集成的一体轴结构,减少了部件数量,简化了整体构造。相较于传统的分体式轴结构,无需额外的连接部件和复杂的装配工序,不仅降低了生产成本,还提高了生产效率,优化了车辆的NVH性能,减少了电驱动总成的尺寸。
