The invention relates to an electric drive system of a two-gear electric automobile. The electric drive system is characterized in that a rotor shaft is hollow, so that a differential mechanism can be arranged inside the rotor shaft; a synchronizer is arranged on an inner gear ring; a first-gear engagement gear ring and a second-gear engagement gear ring are arranged on the synchronizer in an engaged manner, the first-gear engagement gear ring is fixedly connected to a gusset, and the second-gear engagement gear ring is connected to a differential shaft through keys, so that a gear shifting structure is formed; the differential shaft is hollow, so that a gear shaft of a right main reduction gear can be arranged inside the differential shaft. The electric drive system has the advantages that the high integration of a motor, a transmission and the differential mechanism can be realized, and the power performance of the electric automobile is improved.
