The invention discloses a three-wheel linkage suspension robot chassis, which relates to the technical field of walking mechanisms and structurally comprises a chassis body and three-wheel linkage assemblies symmetrically arranged on the left side and the right side of the chassis body. The three-wheel linkage assembly comprises a middle driving wheel, a front universal wheel and a rear universal wheel and further comprises a front damping rocker mechanism connected with the driving wheel and the front universal wheel, a rear rocker mechanism connected with the driving wheel and the rear universal wheel and a connecting rod connected with the front damping rocker mechanism and the rear rocker mechanism. When the chassis goes uphill or the front side of the chassis is impacted by ground protrusions, the front universal wheels are lifted under upward acting force, meanwhile, the driving wheels are pressed downwards through the front damping rocker mechanisms, when the chassis goes downhill or the driving wheels cross obstacles, the front universal wheels move downwards, meanwhile, upward force is provided for the driving wheels through the front damping rocker mechanisms, and the driving wheels are driven to move downwards. And the rear universal wheel is pressed down through the rear rocker mechanism under the action of the connecting rod. The operation stability of the chassis can be improved, and the grounding performance of the universal wheels and the road holding force of the driving wheels are improved.

    本发明公开一种三轮联动的悬挂机器人底盘,涉及行走机构技术领域,其结构包括底盘本体和对称布置于底盘本体左右两侧的三轮联动组件;三轮联动组件包括中间驱动轮、前万向轮和后万向轮,还包括连接驱动轮和前万向轮的前阻尼摇杆机构、连接驱动轮和后万向轮的后摇杆机构、连接前阻尼摇杆机构和后摇杆机构的连杆;在底盘进行上坡或者前侧受到地面凸起的冲击时,前万向轮受到向上的作用力抬高,同时通过前阻尼摇杆机构下压驱动轮,在底盘进行下坡或者驱动轮跨越障碍时,前万向轮向下运动,同时通过前阻尼摇杆机构给驱动轮提供向上的力,在连杆作用下通过后摇杆机构下压后万向轮。本发明可以提高底盘运行平稳性,增加万向轮的接地性与驱动轮的抓地力。
