The invention discloses a variable diameter wheel with a distribution compliant mechanism, which comprises a left hub and a right hub: two groups of flat springs, one group is a plurality of first flat springs which are uniformly distributed around the circumference of the left hub, the other group is a plurality of second flat springs which are uniformly distributed around the circumference of the right hub, the first flat springs and the second flat springs are respectively arranged on the left hub and the right hub, and the first flat springs and the second flat springs are respectively arranged on the left hub and the right hub. The width directions of the first flat spring and the second flat spring are parallel to the axial direction of the variable-diameter wheel; the wheel foot blocks are arranged in the circumferential direction of the wheel body; wherein each caster block is fixedly connected with a first flat spring and a second flat spring, the first flat spring and the second flat spring are symmetrically arranged based on the center line of the caster block, and the first flat spring and the second flat spring are relatively bent. Through relative rotation of the left hub and the right hub, the two sets of leaf springs are bent and deformed to achieve wheel diameter change. The variable-diameter wheel can walk on various complex terrains such as highways, deserts, gobi, farmlands, the surfaces of the moon or the Mars and the like in all terrains, and is a non-pneumatic tire with high trafficability.
本发明公开了一种具有分布柔顺机构的可变直径轮,包括:左轮毂和右轮毂:两组片弹簧,一组是若干环绕左轮毂周向均布的第一片弹簧,另一组是若干环绕右轮毂周向均布的第二片弹簧,第一片弹簧、第二片弹簧分别安装于左轮毂、右轮毂上,第一片弹簧、第二片弹簧的宽度方向均平行于可变直径轮轴向;多个沿轮体周向排布的轮脚块;其中,针对每个轮脚块,均固定连接有第一片弹簧和第二片弹簧,第一片弹簧和第二片弹簧基于轮脚块中心线对称布置,第一片弹簧和第二片弹簧相对弯曲。通过左、右轮毂的相对转动,使两组片弹簧弯曲变形实现轮径变化。该可变径直径轮能在公路、沙漠、戈壁、农田、月球或火星表面等多种复杂地形上实现全地形行走,是一种高通过性非充气轮胎。
