The electric steering system comprises a frame, a steering structure, a steering engine structure and a steering drag link, the steering structure comprises a steering knuckle body, the steering engine structure is arranged on the frame, one end of the steering engine structure is used for being connected with a transmission shaft of a steering wheel, and the other end of the steering engine structure is provided with an output interface; one end of an input interface of the steering drag link is connected with the output interface, the other end is connected with the steering knuckle body, and the linear distance between the input interface of the steering drag link and a plate spring front support lug of the suspension system is smaller than a first set value; the steering engine structure is configured as follows: when the transmission shaft of the steering wheel drives one end of the steering engine structure to move, the output interface drives the steering drag link to linearly displace so as to drive the steering knuckle body to rotate. The linear distance between the steering drag link input interface and the plate spring front support lug of the suspension system is smaller than the first set value, and the difference between the motion trails of the steering drag link input interface and the suspension plate spring front support lug and the motion interference amount of the electric steering system and the suspension system are reduced.
本申请涉及一种电动转向系统及其汽车,其包括:车架、转向结构、转向机结构和转向直拉杆,转向结构包括转向节本体,转向机结构设置于车架上,转向机结构一端用于与方向盘的传动轴连接,另一端设置有输出接口;转向直拉杆的输入接口一端与输出接口连接,另一端与转向节本体连接,转向直拉杆的输入接口与悬架系统的板簧前支耳直线距离小于第一设定值;转向机结构配置为:方向盘的传动轴驱使转向机结构一端运动时,输出接口驱使转向直拉杆直线位移,以驱动转向节本体转动。本发明将转向直拉杆输入接口与悬架系统的板簧前支耳直线距离小于第一设定值,减小转向直拉杆输入接口与悬架板簧前支耳运动轨迹的差距以及电动转向系统和悬架系统的运动干涉量。
