The invention discloses a two-gear hybrid power gearbox of a U-shaped stator double-motor double-planet-row structure, and belongs to the technical field of hybrid power gearboxes, the two-gear hybrid power gearbox comprises an engine and a gearbox shaft arranged below the engine, and one side of the engine is provided with a set of power generation motors EM1 and a set of driving motors EM2; rotors of the power generation motor EM1 and the driving motor EM2 are arranged in a coaxial nesting mode and share one U-shaped motor stator, an output shaft of the driving motor EM2 is connected with a second planet row planet carrier C2, and the two motors (the driving motor EM2 and the power generation motor EM1) share one stator and are coaxially arranged, so that the axial size of the whole gearbox is greatly shortened, and the transmission efficiency is improved. Meanwhile, a double-planet-row and gear-shifting structure is adopted, the speed ratio range is widened, and the requirements for the rotating speed change range and the torque of the motor are lowered; the transmission efficiency of the gearbox is higher, the integration degree is higher, layout is easy, parts are reduced, and the cost is reduced.
本发明公开了一种U型定子双电机双行星排构型的两档混合动力变速箱,属于混合动力变速箱技术领域,包括发动机和设置在发动机下方的变速箱轴,发动机的一侧设置有一组发电电机EM1和一组驱动电机EM2,发电电机EM1和驱动电机EM2的转子采用同轴嵌套的方式布置,且共用一个U形电机定子,驱动电机EM2的输出轴连接有第二行星排行星架C2,通过两个电机(驱动电机EM2和发电电机EM1)共用一个定子的同轴布置,使得整个变速箱的轴向尺寸大为缩短,同时采用双行星排并且可以换挡的构型,提高了速比范围,也降低了对电机的转速变化范围以及转矩的要求;使得变速箱传动效率更高、集成度更高、易于布局、减少了零部件、降低了成本。
