The invention discloses a double-motor electric drive assembly system for a pure electric vehicle, which comprises a power drive system which comprises a main drive unit, a planetary gear differential assembly and a power release mechanism, the main drive unit and the auxiliary drive unit transmit power to the planet wheel differential assembly through a main drive motor and an auxiliary drive motor respectively and finally output the power to a wheel half shaft. The double-motor electric drive system is simple and compact in structure and simple in control logic, when the vehicle is started and starts to run, the double motors are started at the same time so that the acceleration performance and the climbing performance of the whole vehicle can be improved, and when the vehicle system at the high vehicle speed does not need large power performance, the power disengaging mechanism is in a disengaging state; the auxiliary drive motor stops working after power interruption, and the vehicle is powered by the main drive motor, so that the energy consumption of the whole vehicle is reduced.
本发明公开了一种纯电动车用双电机电驱动总成系统,包括:动力驱动系统,所述动力驱动系统包括主驱单元、主驱单元、行星轮式差速器总成以及动力脱开机构,所述主驱单元和辅驱单元分别通过主驱电机和辅驱电机将动力传递给到行星轮差速器总成并最终输出到车轮半轴上。本发明双电机电驱动系统结构简单紧凑,控制逻辑简单,当车辆启动并开始行驶时双电机同时启动由此提升整车的加速性能和爬坡性能,当车速较高车辆系统不需要较大动力性能时,动力脱开机构处于脱开状态,辅驱电机动力中断停止工作,车辆由主驱电机提供动力,由此降低整车能耗。
