The invention relates to the technical field of transmission, in particular to a double-motor stepless speed change electric drive system. The double-motor stepless speed change electric drive system comprises a first motor, a second motor, a planetary gear train, a pedal crankshaft, a sun wheel overrun clutch and a gear ring overrun clutch. The sun gear and/or the gear ring are/is set as power input, and the planet carrier is set as power output; a rotor of the first motor can be connected with the sun gear, and a rotor of the second motor can be connected with the gear ring through the gear ring overrunning clutch. The gear ring is locked by the gear ring overrun clutch and can only rotate in the forward direction. The pedal crank shaft is connected with the sun gear through the sun gear overrun clutch so that torque can only be transmitted from the pedal crank shaft to the sun gear. Therefore, the double motors can cooperate with the planetary gear train to jointly meet the speed change requirement.

    本发明涉及传动技术领域,具体而言,涉及一种双电机无级变速电驱系统。双电机无级变速电驱系统包括第一电机、第二电机、行星齿轮系、脚踏板曲柄轴、太阳轮超越离合器、齿圈超越离合器;太阳轮和/或齿圈设置为动力输入,行星架设置为动力输出;第一电机的转子能够与太阳轮连接,第二电机的转子能够通过齿圈超越离合器与齿圈连接;齿圈被齿圈超越离合器锁止,齿圈只能正向旋转。脚踏板曲柄轴通过太阳轮超越离合器与太阳轮连接,以使转矩只能由脚踏板曲柄轴向太阳轮传动。如此能够采用双电机协同配合行星齿轮系共同完成变速需求。
