The invention relates to the field of vehicle driving, in particular to a dual-motor pure electric driving system and a vehicle. The system comprises a main driving motor, an auxiliary driving motor,a speed reducing mechanism and a clutch, the auxiliary driving motor is connected with the first power end of the speed reducing mechanism, the second power end of the speed reducing mechanism is connected with one end of the clutch, the other end of the clutch is connected with the first power end of the main driving motor, and the second power end of the main driving motor is connected with a system output shaft; the clutch is arranged between the speed reducing mechanism and the main driving motor, when the main driving motor independently works in the low-torque and low-power forward direction, through the separation function of the clutch, reluctance torque loss and transmission internal loss caused by follow-up of the auxiliary driving motor and the speed reducing mechanism are avoided, and the energy utilization rate is increased; and when the vehicle runs at a high speed, the vehicle is directly and efficiently driven by the main driving motor through the separation function ofthe clutch, so that the speed proportion reduction caused by a speed reducing mechanism is avoided, and the high-speed driving of the vehicle is realized.
本发明涉及车辆驱动领域,特别是一种双电机纯电动驱动系统及车辆。该系统包括主驱动电机、副驱动电机、减速机构和离合器,副驱动电机连接减速机构的第一动力端,减速机构的第二动力端连接离合器的一端,离合器的另一端连接主驱动电机的第一动力端,主驱动电机的第二动力端连接系统输出轴;通过在减速机构与主驱动电机之间设置一个离合器,在主驱动电机单独低扭矩、低功率正向工作时,通过离合器的分离功能,避免了副驱动电机和减速机构随动带来的磁阻转矩损耗以及变速器内部损耗,提高了能量利用率;而且在车辆高速运行时,通过离合器的分离功能,采用主驱动电机直接高效驱动车辆,避免了通过减速机构造成的速度比例降低,实现车辆的高速驱动。
