The invention discloses a spline sealing connection system of electric drive axle assembly. The system comprises a drive motor, a main speed reducer and a rear axle, an inner cavity, an inner spline and an inner column cavity are sequentially formed in the outer end of a motor output shaft in the drive motor, one end of the inner column cavity is communicated with the inner cavity through the inner spline, the other end of the inner column cavity is communicated with the environment outside the drive motor, an outer spline, a groove and a driving gear are sequentially arranged on a speed reducer input shaft in the main speed reducer, one end of the outer spline is located outside the main speed reducer, the other end of the outer spline is connected with the driving gear through the groove, an O-shaped sealing ring is arranged on the periphery of the groove in a sleeved mode, one end of the outer spline is correspondingly matched with an inner spline in an inserted mode, and lubricating grease is arranged in the inner cavity. According to the design, the lubricating effect is good, the friction reduction effect is high, the application cost is low, and application and popularization are facilitated.
