The invention relates to a double-motor electric drive axle power transmission system which comprises a first motor, a second motor, a transmission assembly, a speed reducer assembly and a differential mechanism assembly. A first motor and transmission assembly is arranged at one end of the differential mechanism assembly; a second motor and speed reducer assembly is arranged at the other end of the differential mechanism assembly; through the gear shifting action of the sliding meshing sleeve, the power output by the first motor achieves three-level two-gear speed changing and torque adjusting through the transmission assembly, the power is transmitted to the differential assembly, the power output by the second motor is transmitted to the differential assembly through the speed reducer assembly, and the differential assembly achieves power converging through an output driven gear h and outputs the power from half shafts. The half shafts transmit power to wheels connected with the half shafts so as to drive the vehicle to run. The double-motor transmission has the advantages of being short in axial width, compact in structure, light in weight, capable of saving space and facilitating whole vehicle arrangement, meanwhile, due to double-motor arrangement, it is guaranteed that power is not interrupted in the gear shifting process, and the power requirement of a large-tonnage vehicle type is met while motor efficiency is improved.
