The invention belongs to the technical field of wheel-track composite deformation wheels, particularly relates to a wheel-track composite deformation wheel and a liftable wheel-track-foot composite active suspension chassis, and solves the problems that an existing deformation wheel is complex in structure, small in approach angle due to structural limitation and non-ideal in trafficability to complex and severe terrains. The device comprises a crawler belt, a main body supporting part and a two-way telescopic driving assembly, the main body supporting part comprises four sub-supporting modules, the four sub-supporting modules form a closed ring frame used for installing the crawler belt, and a deformation module is used for driving the closed ring frame to deform so that the crawler belt can be in a circular working state and an oval working state; the two telescopic ends of the two-way telescopic driving assembly are hinged to the closed ring frame and further provided with driving modules used for driving the crawler belt to rotate, and each driving module comprises a driving wheel meshed with the crawler belt and enabling the crawler belt to be tensioned. The deformable wheels, the cuboid frame and the four sets of fork arm suspension modules are connected to form the liftable wheel-track-foot composite active suspension chassis.
本发明属于轮履复合变形轮技术领域,具体为一种轮履复合变形轮及可升降轮履足复合主动悬架底盘,解决了现有变形轮结构复杂,受结构限制接近角较小,对复杂恶劣地形的通过性能不理想的问题,其包括履带、主体支撑部和双向伸缩驱动组件,主体支撑部包括四块子支撑模块,四块子支撑模块形成用于安装履带的封闭环架,变形模块用于驱动封闭环架变形以使履带呈现圆形和椭圆形两种工作状态;双向伸缩驱动组件的两个伸缩端分别与封闭环架相铰接,双向伸缩驱动组件的两个伸缩端还分别安装有用于驱动履带转动的驱动模块,驱动模块包括与履带啮合且使履带张紧的主动轮。变形轮与长方体框架以及四套叉臂悬架模块连接后形成可升降轮履足复合主动悬架底盘。
