The invention discloses a multi-gear electric drive axle assembly structure which effectively utilizes the spaces on the two sides of an axle assembly, improves the overall reliability of an electric drive axle, and enables a lubricating structure to be simple and the lubricating reliability to be high. The axle assembly comprises an axle sub-assembly; the auxiliary box gearbox comprises an auxiliary box shell, an auxiliary box rear cover, an auxiliary box oil pipe and an auxiliary box gear shaft assembly. An auxiliary box motor; the main box gearbox comprises a main box shell, a main box gear shaft assembly, a main box rear cover, an oil pump, a main box upper oil pipe and a main box lower oil pipe. A main box motor; and an inter-bridge oil pipe. The auxiliary box motor and the auxiliary box gearbox form an auxiliary box sub-assembly, the main box motor and the main box gearbox form a main box sub-assembly, and the main box sub-assembly and the auxiliary box sub-assembly are located on the two sides of the axle sub-assembly respectively. A main box shell of the main box gearbox and an auxiliary box shell of the auxiliary box gearbox are fixedly connected to the positions, corresponding to shell bodies on the two sides of a differential mechanism gear, of the axle subassembly through bolts respectively, and a main box external oil way connector is arranged on the main box rear cover.
