The invention relates to a three-point supporting frame structure, and the structure comprises a first beam, a second beam, a portal connected between the first and second beams at two sides, wheel assemblies connected to the bottoms of the first and second beams, wherein the first and second beams are located on the two sides respectively; one side of the portal is rotationally connected with thefirst beam through a first supporting point, and the other side of the portal is fixedly connected. The wheel assembly connected to the bottom of the second beam comprises a first supporting wheel and a second supporting wheel, a second supporting point is formed between the first supporting wheel and the second beam, and a third supporting point is formed between the second supporting wheel andthe second beam. Three supporting points can be simplified, the three supporting points form a stable three-point supporting structure, three-point supporting forms stable and statically determinate supporting during load distribution, the suspension system can be made into rigid suspension, the structure of the suspension system is simplified, the cost is saved, and the suspension system is suitable for large-scale popularization and application. When the whole vehicle encounters an uneven road surface in the walking process, the first beam swings up and down to adapt to the road surface, andthe key effect on the stability of the whole vehicle is achieved.

    本发明涉及一种三点支撑车架结构,包括分别位于两侧的第一梁和第二梁、连接在两侧第一梁、第二梁之间的门架、连接在第一梁、第二梁底部的轮组件,门架的一侧与第一梁之间通过第一支撑点转动连接,门架的另一侧与第二梁固定连接,连接在第二梁底部的轮组件包括第一、第二支撑轮,第一支撑轮与第二梁之间形成第二支撑点,第二支撑轮与第二梁之间形成第三支撑点。本发明可以简化呈三个支撑点,三个支撑点形成一个稳定的三点支撑结构,三点支撑在载荷分配形成稳定静定的支承,悬挂系统就可以做成刚性悬挂,简化悬挂系统的结构并节省成本,当整车在行走过程中遇到不平的路面可以通过第一梁的上下摆动来适应路面,对整车的稳定性起到关键作用。
