The invention belongs to the technical field of mobile robot chassis, and particularly relates to a wheel suspension system capable of absorbing axial displacement. The system comprises a limiting frame, a mounting frame, a supporting frame and a hub mounting disc, wherein the limiting frame is connected with a chassis frame, the mounting frame is connected with the limiting frame in a sliding mode in the horizontal direction, an elastic reset mechanism is arranged between one side of the mounting frame and the limiting frame, the other side of the mounting frame is hinged to the hub mountingdisc through the supporting frame, and the supporting frame is hinged to the chassis frame through a shock absorber. Axial displacement generated by wheels can be absorbed during vibration reduction of a robot, so the situation that the walking stability is affected due to wheels rub the grounding in the axial direction is avoided.
本发明属于移动机器人底盘技术领域,特别涉及一种可吸收轴向位移的轮子悬挂系统。包括限位架、安装架、支撑架及轮毂安装盘,其中限位架与底盘架连接,安装架与限位架可沿水平方向滑动地连接,安装架的一侧与限位架之间设有弹性复位机构,安装架的另一侧通过支撑架与轮毂安装盘铰接,支撑架通过减震器与底盘架铰接。本发明可以在机器人减振动作时吸收轮子产生的轴向位移,以免车轮与地面在轴向发生摩擦,影响行走平稳性。
