The invention belongs to the technical field of electric drive axles, and discloses a double-motor electric drive axle assembly. Wherein the motors comprise a first motor and a second motor, the first motor is rotationally connected with a first driving gear through a first input shaft, the first driving gear is meshed with a first driven gear, and the first driven gear drives a main output shaft to rotate; the first driven gear is further meshed with a second driven gear, a second input shaft is rotationally connected to the second driven gear, a gear shifting gear is connected to the second input shaft, a gear shifting mechanism is installed on the gear shifting gear and drives a gear shifting gear sleeve to move, and the gear shifting gear sleeve can be connected with the two sets of gears in a meshed mode at the same time. A first-gear driving tooth and a second-gear driving tooth are installed on the two sides of the gear shifting gear respectively, the first-gear driving tooth is meshed with a first-gear driven tooth, the second-gear driving tooth is meshed with a second-gear driven tooth, and the first-gear driven tooth is rotationally connected with the second-gear driven tooth through an intermediate shaft. The problem that in the prior art, power interruption and pause occur during gear shifting of a double-motor electric drive axle assembly is solved.
