The invention discloses an independent belt wheel type electric power steering device, which comprises a shell, an integrated motor controller, an input shaft and a belt pulley output shaft, and is characterized in that a first bearing, a first seal and a sensor stator are arranged on the input shaft, and a second bearing, a second seal and a sensor rotor are arranged on the belt pulley output shaft; an input shaft and a belt pulley output shaft are connected through a cylindrical pin and a torsion bar, a wire harness is connected with a sensor stator and an integrated motor controller, the input shaft recognizes the steering instruction requirement of a driver, transmission of angle and torque signals is achieved, and a belt pulley installed on the integrated motor controller adopts a belt pulley type speed reducing mechanism. The output torque of the motor is transmitted to the output shaft of the belt pulley through the belt, rotation of the motor is converted into rotation of the output shaft, the effect of torque speed reduction and torque increase is achieved, and an electric power steering device is jointly formed. According to the independent belt wheel type electric power-assisted steering device, electric power assistance can be carried out on a steering gear of a whole vehicle, the steering instruction requirement is intelligently controlled, and the electric and intelligent refitting requirement of a steering system is met.
