The invention discloses an electric power steering device of a new energy automobile, and belongs to the technical field of new energy automobiles. The electric power steering device of the new energyautomobile comprises a transmission rod, a first limiting ring is fixedly connected to one side of the transmission rod, a driving rack is arranged on the side, close to the first limiting ring, of the transmission rod, a driven rack is fixedly connected to the bottom end of the transmission rod, and a second limiting ring is fixedly connected to the bottom end of the transmission rod. Accordingto the electric power steering device of the new energy automobile, the ECU controller calculates the running current required by the power-assisted motor according to the torque signal, and after being electrified, the power-assisted motor drives the power-assisted motor rotating shaft to rotate, so that the second thread in the transmission pair body is driven to linearly rotate on the outer surface of the first thread formed in the transmission shaft, then the steering wheel pushes the first wheel and the second wheel to steer together, and the purpose of power-assisted steering is achieved.

    本发明公开了一种新能源汽车电动助力转向装置,属于新能源汽车技术领域。一种新能源汽车电动助力转向装置,包括传动杆,所述传动杆的一侧固定连接有第一限位环,所述传动杆靠近第一限位环的一侧开设有主动齿条,所述传动杆的底端固定连接有从动齿条,所述传动杆的底端固定连接有第二限位环。该新能源汽车电动助力转向装置,ECU控制器根据扭矩信号计算助力电机所需要的运行的电流,助力电机通电流后将会带动助力电机转轴进行转动,从而带动传动副本体内部的第二螺纹在传动轴所开设的第一螺纹的外表面进行直线转动,进而使得方向盘一起推动第一车轮和第二车轮进行转向,进而实现转向助力的目的。
