The invention relates to a multi-element coupling elastic deformation planet wheel, and belongs to the technical field of deep space exploration, the multi-element coupling elastic deformation planet wheel comprises a hub, a plurality of elastic sheets, a first elastic ring and an elastic tread, the plurality of elastic sheets are annularly fixed on two sides of the periphery of the hub at intervals; the two first elastic rings are correspondingly fixed to the elastic pieces on the two sides of the hub shaft through first connecting pieces respectively. The elastic tread is arranged on the peripheral sides of the hub and the elastic pieces in a sleeving mode and fixed to the two first elastic rings through second connecting pieces. The multiple elastic pieces, the two first elastic rings and the elastic tread are used for providing elastic support for the hub at the same time, a multi-element coupling elastic deformation structure can be formed on the peripheral side of the hub, and the multi-element coupling elastic deformation structure is compact in design, simple in structure and low in manufacturing cost, and can also be used for manufacturing the hub on the premise that the yield limit strength of materials is not changed. And the elastic deformation and the bearing capacity of the planet wheel are greatly improved.
本发明涉及一种多元耦合弹性变形星球车轮,属于深空探测技术领域,包括:轮毂、多个弹片、第一弹性圈及弹性胎面,多个弹片呈环形间隔固定在轮毂外周的两侧;第一弹性圈为两个且分别通过第一连接件对应固定在轮毂轴两侧的弹片上;弹性胎面套设在轮毂和多个弹片的外周侧且通过第二连接件固定在两个第一弹性圈上。本发明利用多个弹片、两个第一弹性圈和弹性胎面同时为轮毂提供弹性支撑,可以在轮毂的外周侧构成一个多元耦合弹性变形结构,该多元耦合弹性变形结构不仅设计紧凑、结构简单、造价低廉,还可以在不改变材料屈服极限强度的前提下,大幅提升星球车轮的弹性变形量和承载能力。
