The invention relates to a dual-motor dynamic coupling driving system based on a double-row compound planetary gear train. The dual-motor dynamic coupling driving system comprises a first motor, a first input shaft, a second motor, a second input shaft, a double-row compound planetary gear train mechanism, a brake and a power output mechanism, the double-row compound planetary gear train mechanism comprises a gear ring, a front planetary gear row and a rear planetary gear row; the front planetary gear row and the rear planetary gear row are coaxially and fixedly connected; the gear ring is meshed with the front planetary gear row and the rear planetary gear row; the first motor is connected with the gear ring through a first input shaft; the second motor is connected with the front planetary gear row through a second input shaft; the brake is arranged in the middle of the rear planetary gear row; the power output mechanism is coaxially connected to the output end of the rear planetary gear row. The power driving system provided by the invention can realize four driving modes in total, and due to the existence of the four working modes, the motor can more work in an efficient interval on the premise of meeting the driving requirement.

    本发明涉及一种基于双排复合行星轮系的双电机动力耦合驱动系统,包括第一电动机、第一输入轴、第二电动机、第二输入轴、双排复合行星轮系机构、制动器和动力输出机构;双排复合行星轮系机构包括齿圈、前行星齿轮排和后行星齿轮排;前行星齿轮排和后行星齿轮排同轴固联;所述齿圈与前行星齿轮排和后行星齿轮排啮合;第一电动机通过第一输入轴与齿圈连接;第二电动机通过第二输入轴与前行星齿轮排连接;制动器设置在后行星齿轮排的中部;动力输出机构同轴连接在后行星齿轮排的输出端。本发明提出的动力驱动系统一共能够实现四种驱动模式,这四种工作模式的存在,这使得电动机能够在满足驾驶要求的前提下,更多地工作在高效区间。
