The invention relates to the technical field of transmission, in particular to a double-motor electric drive system which specifically comprises a box body, a first planetary gear train, a second planetary gear train, a first motor, a first motor shaft, a second motor, a second motor shaft, a fifth transmission wheel, a first transmission wheel and a pedal shaft. At least one second planet shaft is connected with a fifth transmission wheel; the first transmission wheel is in transmission fit with the fifth transmission wheel through the second transmission wheel; a third transmission wheel on the pedal shaft is in transmission fit with the gear ring; the double-motor electric drive system achieves power confluence at two positions, wherein the first position is that manpower treading power input through a pedal shaft and input power of a first motor achieve first-time power confluence at the position of a gear ring, and the second position is that power transmitted by the gear ring and input power of a second motor achieve second-time power confluence at the position of a fifth transmission wheel. In this way, stepless speed change adjustment can be achieved through double-motor regulation and control, the overall structure is simple, and cost is lower.
本发明涉及传动技术领域,具体而言,涉及一种双电机电驱动系统,具体包括箱体、第一行星齿轮系、第二行星齿轮系、第一电机、第一电机轴、第二电机、第二电机轴、第五传动轮、第一传动轮、脚踏轴;至少一个第二行星轴与第五传动轮连接;第一传动轮通过第二传动轮与第五传动轮传动配合;脚踏轴上的第三传动轮与齿圈传动配合;双电机电驱动系统在两处部位实现功率合流:第一处是通过脚踏轴输入的人力踩踏功率与第一电机输入功率在齿圈处实现第一次功率合流,第二处是齿圈传递的功率与第二电机的输入功率在第五传动轮处实现第二次功率合流。如此能够通过双电机调控实现无级变速调节,且整体结构简单、成本更低。
