The invention discloses a drive axle device of an electric automobile, a first planetary mechanism is matched with a first power input assembly to receive the torque of the first power input assembly, a first output assembly is matched with the first planetary mechanism to output the torque, and an adjusting unit comprises a first gear pair for receiving the torque of the first power input assembly and a second gear pair for receiving the torque of the second power input assembly. The first gear pair is connected with the first power input assembly; the auxiliary shaft assembly is in pivot fit with the first gear pair, and the auxiliary shaft assembly is further combined with or separated from the first gear pair so as to transmit or cut off the torque of the first gear pair; the gear ring hub is meshed with the auxiliary shaft assembly, and the gear ring hub is fixed to the first planetary mechanism so that torque from the auxiliary shaft assembly can be loaded to the first output assembly through the first planetary mechanism, and therefore the torque and the rotating speed of the first output assembly can be adjusted. The invention has the advantages of high integration level and simple structure.
