The invention relates to a mechanical reinforcement wheel foot composite lunar rover wheel, and belongs to the technical field of deep space exploration, the mechanical reinforcement wheel foot composite lunar rover wheel comprises an inner wheel, an outer wheel and a mechanical reinforcement mechanism, the inner wheel and the outer wheel of the mechanical reinforcement wheel foot composite lunar rover wheel are concentrically and fixedly connected and rotate around a wheel shaft, and a sliding block is hinged to the inner wheel and is in sliding connection with a reinforcement rod; the boosting rod penetrates through the sliding block, is rotationally connected with the outer end of the eccentric rod and can rotate along with the inner wheel, the relative dip angle alpha between the eccentric rod and the frame can be actively adjusted through the dip angle motor, the eccentric rod is locked by the worm gear reducer, and the eccentric rod, the dip angle adjusting unit, the sliding block and the boosting rod jointly form a mechanical boosting mechanism; in the rolling process of the wheel-foot composite wheel, the extending position and the extending length of the reinforcement rod can be actively adjusted in real time according to the lunar surface condition, the traction force and the passing ability of the wheel are improved, meanwhile, the continuous rolling characteristic of the round wheel is kept, and the lunar rover has good movement stability.

    本发明涉及一种机械增力轮足复合月球车车轮,属于深空探测技术领域,包括:内轮、外轮及机械增力机构,本发明的内轮与外轮同心固连并绕轮轴转动,滑块铰接于内轮并与增力杆滑动连接,增力杆穿过滑块与偏心杆外端转动连接并可随内轮一起转动,偏心杆可通过倾角电机主动调整与车架的相对倾角α,并由蜗轮蜗杆减速器锁定,偏心杆、倾角调节单元、滑块、增力杆共同形成机械增力机构;轮足复合车轮滚动过程中增力杆的伸出位置和伸出长度可根据月面情况进行实时主动调整,提高车轮的牵引力和通过性,同时也保持了圆形车轮连续滚动的特点,使得月球车具有较好的运动平稳性。
