A power shaft structure of an electric drive assembly is disclosed. The power shaft structure comprises a main shaft (1), a right end of the main shaft (1) is located inside a motor (2) and fixedly connected to a rotor (3) of the motor (2), and a left end of the main shaft (1) is located inside a reducer (4) and fixedly connected to a driving gear (5) and a parking gear (6) of the reducer (4). At least one side of the driving gear (5) is provided with an axially extending flange, and at least one side of the parking gear (6) is provided with an axially extending flange. A bushing (8) is provided between an inner hole of one flange at one side of the driving gear (5) and the main shaft (1) as weel as between an inner hole of one flange at one side of the parking gear (6) and the main shaft (1) for radial positioning of the driving gear (5) and the parking gear (6), so that the driving gear (5), the parking gear (6), and the main shaft (1) are on the same axis, thereby improving the stability and NVH performance of the electric drive assembly.
