The invention belongs to the technical field of motor vehicle drive axles, and discloses a dual-motor-driven two-gear speed change integrated drive axle for a vehicle, a driving method and application. The dual-motor-driven two-gear speed change integrated drive axle for the vehicle comprises a drive axle and a dual-motor-driven two-gear speed change device. The drive axle is used for receiving power from the double-motor-driven two-gear speed change device and carrying out multi-mode power operation. A double-motor-driven two-gear speed change device is used for being freely combined into various working modes suitable for vehicle running working conditions according to different gear modes in the driving process and the number of motors participating in driving in the driving process. The comprehensive performance of the vehicle can be improved; the drive motor, the speed change device and the drive axle are integrally designed, the space utilization rate can be increased, and convenience is provided for arrangement of other parts. In general, the dual-motor-driven two-gear speed change integrated drive axle for the commercial truck has great potential in the aspects of improving the dynamic property and economical efficiency of the truck.
