The invention relates to an electric drive assembly system of an electric vehicle, and discloses an integrated axle assembly which comprises an axle housing, a main speed reducer and a half shaft arearranged in the axle housing, the main speed reducer comprises a differential mechanism, and the differential mechanism is installed on the axle housing; a first main reduction gear is connected withthe differential mechanism, and a second main reduction gear is meshed with the first main reduction gear; a one-way clutch comprises an inner ring assembly and an outer ring assembly which are connected with the output shaft of a second motor and the second main reduction gear respectively. One end of the half shaft is connected with the differential mechanism; a transmission is arranged in frontof the half shaft; a first motor is arranged on one side of a transmission; the second motor is located behind the half shaft and arranged on the side, opposite to the first motor, of the main speedreducer. In addition, the invention further discloses a vehicle comprising the integrated axle assembly. According to the invention, when the rotating speed is too high, the motor controller is prevented from being damaged by excessive current generated by the motor; and the safety of the whole vehicle and the driving stability of the whole vehicle can be guaranteed, and driving and riding are more comfortable.
