The invention discloses a dual-motor driving system and an engineering vehicle, the dual-motor driving system comprises a first driving motor, a second driving motor and a gearbox integrated with a power takeoff, the output end of the first driving motor is connected with an input shaft of the gearbox, an output shaft of the gearbox is connected with an axle through a transmission shaft, and an output shaft of the power takeoff is connected with an oil pump; the second driving motor and the first driving motor are coaxially connected in series through a clutch mechanism; during loading operation, the clutch mechanism separates power of the two motors, and the first driving motor drives independently; when the vehicle runs, the clutch mechanism enables the two motors to be in power connection, and the two motors jointly drive. The system is high in integration level, low in cost and convenient for whole vehicle arrangement, the motor runs in a high-efficiency area when the engineering vehicle is in a running mode and an operation mode, and the running efficiency of the motor is improved.

    本发明公开了一种双电机驱动系统及工程车辆,所述双电机驱动系统包括第一驱动电机、第二驱动电机和集成取力器的变速箱,第一驱动电机输出端连接变速箱输入轴,变速箱输出轴通过传动轴连接车桥,取力器输出轴连接油泵,第二驱动电机与第一驱动电机通过离合机构同轴串联;上车作业时,离合机构将两电机动力分离,第一驱动电机单独驱动;车辆行驶时,离合机构将两电机动力接合,两电机共同驱动。本发明集成度高、成本低、便于整车布置,工程车辆在行驶模式和作业模式下电机均运行在高效区,提高了电机运行效率。
