The invention relates to the technical field of new energy automobiles, and discloses a new energy automobile power-assisted steering device which comprises a steering wheel direct-connection tubular shaft, a steering wheel mechanism is fixedly installed on the top of the steering wheel direct-connection tubular shaft, and the bottom end of the steering wheel direct-connection tubular shaft is rotationally sleeved with a bearing seat. A shaft body structure (a steering wheel direct connection pipe shaft) of a steering wheel and a rotation control shaft structure (a steering driving shaft bracket) of the steering wheel are designed in a separated mode, namely electronization is utilized for control, and torque data of the steering wheel direct connection pipe shaft after the steering wheel mechanism rotates are sensed through a dynamic torque sensor; the electric signal is transmitted to the electronic controller, so that the steering adjusting motor part is calculated and controlled, the electronized-controlled direction rotation assisting power is realized, the development requirements of electronization and intelligentization of the new energy automobile are met to a great extent, the effect of improving the driving comfort is achieved, and the safety is guaranteed.

    本发明涉及新能源汽车技术领域,公开了种新能源汽车转向助力装置,包括方向盘直连管轴,所述方向盘直连管轴的顶部固定安装有方向盘机构,方向盘直连管轴的底端转动套接有轴承座。通过设置方向盘的轴体结构(方向盘直连管轴)与转向的转动控制轴结构(转向驱动轴架)采用分离式设计,即利用电子化进行控制,通过动态扭矩传感器对方向盘机构转动后的方向盘直连管轴的转矩数据进行感应,并将电信号输送至电子控制器,进而实现计算控制转向调节电机部,已实现电子化控制的方向转动助力,从而极大程度上满足了新能源汽车的电子化、智能化的发展需求,达到了提升驾驶舒适性的效果,进而保障了安全性。
