The invention discloses an integrated electric drive axle system. The integrated electric drive axle system comprises an all-in-one drive unit. The driving all-in-one device comprises a motor controller, a driving motor, a multi-gear gearbox and a main speed reducer; the motor controller is arranged on the shell of the driving motor and is used for controlling the operation of the driving motor; a motor winding of the driving motor, the multi-gear gearbox and a change gear train of the main speed reducer are all arranged in an axle housing of the axle, the driving motor is in power connection with the multi-gear gearbox, the multi-gear gearbox is in power connection with the main speed reducer, and the main speed reducer is in power connection with hubs at the two ends of the axle. A moving gear is arranged in the multi-gear gearbox, and the multi-gear gearbox outputs different speed ratios through the moving gear. By the adoption of the scheme, all-in-one driving is arranged on the axle in an integrated mode, and therefore the problems that a traditional electric drive axle does not have multiple gears, and a motor and wheel power cannot be disconnected are solved.
