The invention discloses a double-electric-drive-axle structure of a heavy-duty commercial vehicle, and belongs to the technical field of automobiles, the double-electric-drive-axle structure comprises a first electric drive axle, a second electric drive axle and a third electric drive axle, the first electric drive axle comprises a first drive motor, a speed reducer and a first differential mechanism; the second electric drive axle comprises a second drive motor, a third drive motor, a two-gear transmission and a second differential mechanism; according to the double-electric-drive-axle multi-drive-mode electric vehicle, the vehicle can be driven independently through a single electric drive axle, the two electric drive axles can jointly drive the vehicle to run, different working modes can be selected according to the running working conditions of the vehicle, and due to the characteristics of the double-electric-drive-axle multi-drive motor and the multi-gear speed changing device, the driving efficiency is improved. Therefore, the heavy-duty commercial vehicle has more working modes for selection, so that the torque is distributed according to the working conditions on the premise of ensuring the dynamic property of the vehicle, the motor is effectively ensured to run in a high-efficiency interval under each working condition, and better economical efficiency is realized.

    本发明公开了一种重型商用车的双电驱动桥构型,属于汽车技术领域,所述双电驱动桥构型包括:第一电驱动桥,所述第一电驱动桥包括第一驱动电机、减速器和第一差速器;第二电驱动桥,所述第二电驱动桥包括第二驱动电机、第三驱动电机、两挡变速器和第二差速器;本发明通过单一电驱动桥可以单独实现对车辆的驱动,也可以两个电驱动桥共同驱动车辆行驶,便于根据车辆的行驶工况选择工作在不同的工作模式,而双电驱动桥多驱动电机和多挡变速装置的特点,使得重型商用车有更多的工作模式可以选择,从而在保证车辆动力性的前提下,根据工况分配转矩,有效保证各工况下电机运行在高效率区间,实现更好的经济性。
