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.

    本发明公开了一种独立带轮式电动助力转向装置,包括壳体、一体电机控制器、输入轴、皮带轮输出轴,其特征在于:输入轴上装有第一轴承、第一密封和传感器定子,皮带轮输出轴上装有第二轴承、第二密封和传感器转子,输入轴和皮带轮输出轴使用圆柱销和扭杆进行连接,线束连接传感器定子和一体电机控制器,输入轴识别驾驶员的转向指令要求,实现角度、扭矩信号的传递,安装在一体电机控制器上的皮带轮,采用带轮式减速机构,电机输出力矩通过皮带传递给皮带轮输出轴,将电机的旋转转化为输出轴的旋转,实现力矩减速增扭的效果,共同构成一个电动助力转向装置。本独立带轮式电动助力转向装置,可对整车转向器进行电动助力,智能控制转向指令要求,实现转向系统电动化、智能化改装需求。
