The invention relates to a deformable wheel (2) with a non-pneumatic load bearing intended to be equipped for vehicles rolling under extreme conditions, such as those encountered on the moon and Mars. The deformable wheel comprises a hub (4), an annular laminated strip (6) comprising a plurality of concentric ferrules assembled together by inserting insertion layers, each of which is composed of a material having a Young's modulus 600000 to 1000 times lower than the Young's modulus of the ferrules, and a plurality of metal cables (8) having an outer diameter comprised between 0.2 mm and 5 mm, each of which is made of a material having a Young's modulus less than that of the ferrules. Each cable, while radially connecting the hub (4) to the laminate strip (6), is secured to the laminate strip on the one hand by means of an outer end (8a) and to the hub by means of an inner end (8b) by means of elastic members (18), so that it can adjust the radial stiffness of the cable, each elastic member being associated with an abutment (12, 14) capable of limiting its deformation.
本发明涉及一种具有非充气承载的可变形车轮(2),意在装备用于在极端条件下(例如在月球和火星上遇到的那些极端条件)滚动的车辆。可变形车轮包括:轮毂(4),包括多个同心套圈的环形层压条带(6),这些套圈通过插入插入层组装在一起,每个插入层由杨氏模量比套圈的杨氏模量低600000到1000倍的材料构成,以及多根外径包括在0.2mm和5mm之间的金属线缆(8),每根线缆在将轮毂(4)与层压条带(6)径向连接的同时,一方面通过外端(8a)与层压条带相固定,另一方面通过内端(8b)借助于弹性构件(18)与轮毂相固定,使其能够调节线缆的径向刚度,每个弹性构件与能够限制其变形的邻接部(12,14)相关联。
