The invention relates to the field of engineering machinery, in particular to a gearbox assembly for double-motor-driven engineering machinery, which comprises a box body, a driving shaft, a first intermediate shaft, a second intermediate shaft and an output shaft are rotatably mounted in the box body, a driving gear is mounted on the driving shaft, a driven gear meshed with the driving gear is mounted on the first intermediate shaft, and a driven gear meshed with the second intermediate shaft is mounted on the output shaft. A first intermediate wheel is rotationally installed on the first intermediate shaft, a first clutch used for fixing the first intermediate wheel is installed on the first intermediate shaft, a second intermediate wheel meshed with the first intermediate wheel is installed on the second intermediate shaft, and an output wheel meshed with the second intermediate wheel is installed on the output shaft. A second motor used for driving the driving shaft to rotate is installed on the box body, and a PTO driving shaft, a PTO2 output shaft and a PTO1 output shaft are rotationally installed in the box body. According to the gearbox assembly, the walking system and the hydraulic working system can work independently; and two power takeoff ports of the gearbox oil supply pump and the working device are arranged, the layout is reasonable, and the maintenance is convenient.
