The invention provides a three-stage planet row speed reduction non-shaft installation bridge assembly, which comprises a motor, three stages of reduction gears, a differential mechanism, an axle tube, a speed reducer and differential mechanism shell and a motor shell, wherein the motor is connected with the differential mechanism through two stages of reduction gears arranged in a planet row modeand then through the third stage of reduction gear, the differential mechanism is connected with the axle tube, and the axes of the three stages of reduction gears are parallel; a motor shaft is coaxial with the axis of an axle, and the three stages of reduction gears and the differential mechanism are integrated into a whole and installed on in the speed reducer and differential mechanism shellabove the axle in a non-shaft mode and coaxially connected with wheels on the two sides; and the motor is arranged in the independent motor shell. According to the invention, three-stage speed reduction is adopted, large-speed-ratio speed reduction is achieved, the torque is increased, and large power output is achieved.
