The invention relates to a dual-motor coupling driving system which comprises a first motor, a second motor, a first input shaft, a second input shaft, a compound planet row mechanism, a first brake, a second brake, a planet gear set shell, an output shaft and a differential mechanism. The first motor is connected with a first planet gear through the first input shaft, the second motor is connected with a sun gear through the second input shaft, and the first brake and the second brake brake the second input shaft and a gear ring respectively. The rotating speeds of the two motors are coupled together through the compound planet row mechanism, the second planet wheel serves as output and transmits power to the reduction gear through a planet carrier, the reduction gear transmits the power to the output shaft, and the power transmitted by the output shaft is shunted through the differential mechanism and then drives an automobile to run. The power driving system can realize four driving modes, and the motor can work efficiently due to the existence of the rotating speed coupling mode, so that the electric energy is saved. Meanwhile, compared with a multi-mode coupling power driving system in an existing research hotspot, the system has the advantages that the structure is simple, and the manufacturing cost is reduced.

    本发明涉及一种双电机耦合驱动系统,包括第一电动机、第二电动机、第一输入轴、第二输入轴、复合行星排机构、第一制动器、第二制动器、行星齿轮组壳体、输出轴和差速器;第一电动机通过第一输入轴与第一行星轮相接,第二电动机通过第二输入轴与太阳轮相接,其中第一、第二制动器分别制动第二输入轴、齿圈。复合行星排机构将两电机的转速耦合在一起,其中第二行星轮作为输出将动力经行星架传递至减速齿轮,减速齿轮将动力传递至输出轴,输出轴传递出的动力经差速器分流后驱动汽车行驶。该动力驱动系统能够实现四种驱动模式,其中由于转速耦合模式的存在使得电动机可以高效地工作,从而节约电能。同时与现有研究热点中的多模耦合动力驱动系统相比,其优势在于结构简单,制造成本降低。
