The invention relates to a steering pull rod system and an automobile, and belongs to the technical field of automobile steering systems. The steering pull rod system comprises a vehicle frame, a direct-drive EPS steering gear and a steering pull rod assembly. The frame comprises two longitudinal beams arranged at an interval and a plurality of cross beams arranged between the two longitudinal beams; the direct-drive EPS steering gear is fixed to the frame and arranged at the front end of the longitudinal beam in the width direction of a vehicle body. The steering pull rod assembly comprises a first steering pull rod and a second steering pull rod, the first steering pull rod is connected to the direct-drive EPS steering gear and arranged in the length direction of the direct-drive EPS steering gear, the second steering pull rod is perpendicularly arranged on the first steering pull rod, and the end, away from the first steering pull rod, of the second steering pull rod is connected with a steering knuckle arm. And the steering knuckle arm is connected to a wheel through a steering knuckle. According to the steering pull rod system, the requirement for height reduction of a cab can be met, and meanwhile the problem that a direct-drive EPS steering gear cannot be reasonably arranged due to the fact that a front overhang of a commercial vehicle is short is solved.

    本申请涉及一种转向拉杆系统及汽车,属于汽车转向系统技术领域。本申请的转向拉杆系统包括车架、直驱式EPS转向器和转向拉杆组件;所述车架包括两根间隔设置的纵梁和设置于两根所述纵梁之间的多根横梁;所述直驱式EPS转向器固定于所述车架,且沿车身宽度方向设置于所述纵梁前端;所述转向拉杆组件包括连接于所述直驱式EPS转向器,且沿所述直驱式EPS转向器长度方向设置的第一转向拉杆,以及垂直设置于所述第一转向拉杆的第二转向拉杆,所述第二转向拉杆远离所述第一转向拉杆的一端连接有转向节臂,所述转向节臂通过转向节连接于车轮。该转向拉杆系统能够实现驾驶室降高需求的同时,解决因商用车前悬较短,导致的无法合理布置直驱式EPS转向器的问题。
