The invention relates to a dual-motor drive axle device which comprises a drive axle shell and two electric power assemblies, the two electric power assemblies are symmetrically arranged on the two sides of a first central axis of the drive axle shell, each electric power assembly comprises a drive motor, a parking brake, a planetary reducer and a drive wheel, the drive motor is connected with the planetary reducer through a half shaft, and the parking brake is connected with the planetary reducer. The planetary reducer is in transmission connection with the driving wheel. The two electric power assemblies are symmetrically arranged, and the driving motors, the parking brakes, the planetary reducers and the driving wheels are arranged at intervals, so that distributed driving can be realized, the rotating speed and the torque of the driving wheels can be more conveniently controlled, the transmission efficiency is improved, and electric power and braking energy are effectively utilized; the two driving motors and the two parking brakes are arranged in the driving axle shell, and the two planetary reducers are arranged in the corresponding driving wheels respectively, so that the space utilization rate of the driving wheels and the driving axle shell can be increased.
