The invention provides a power transmission system. The system is mounted in a blade electric vehicle, and in the system, double drive motors are cooperated with a single planetary row. The power transmission system comprises the two drive motors, wherein the driving moment generated by the drive motors is transmitted to an output shaft through the single planetary row to drive wheels to rotate. Through the drive control of the double motors and by the utilization of rotating speed characteristic and torque characteristics of the single planetary row, both the acceleration performance and the maximum speed of the vehicle can be improved; in addition, the two motors can work in the rotating speed interval with higher efficiency by the utilization of the clockwise and anticlockwise rotation performances of the motors and the rotating speed characteristics of the planetary row; through reasonable arrangement that the drive motors and the planetary row are coaxial, the optimal arrangement of the power transmission system on the finished vehicle chassis space is facilitated.
