The rigid wheel comprises a main hub and an auxiliary hub, the center of the main hub is provided with a deflection structure, one side of the deflection structure is connected with a limiting clutch, and the limiting clutch is used for receiving deflection torque, transmitting the deflection torque to the deflection structure and driving the deflection structure to rotate; the number of the auxiliary hubs is two, the two auxiliary hubs are movably installed on the two sides of the main hub respectively, reset springs are arranged between the auxiliary hubs and the main hub, flexible pull ropes are evenly connected to the edges of the outer sides of the auxiliary hubs, and the other ends of the flexible pull ropes are connected with the deflection structure. Deflection torque is transmitted to the deflection structure through the limiting clutch, the deflection structure is driven to deflect, then the flexible pull rope is pulled, the wheel width of the wheel is compressed, and therefore the problems that the steering resistance of a large-wheel-width rigid wheel is too large, the space carrying size is too large, and the dragging difficulty is too large when a driving and steering motor is damaged are effectively solved.

    本发明公开了一种轮宽可变的星球车刚性车轮及星球车,刚性车轮包括主轮毂和副轮毂,其中,主轮毂中心安装有偏转结构,偏转结构的一侧连接有限位离合器,限位离合器用于接收偏转扭矩传递至偏转结构,并带动偏转结构旋转;副轮毂有两个,分别活动安装于主轮毂的两侧,副轮毂与主轮毂之间有复位弹簧,且副轮毂的外侧边缘均匀连接柔性拉绳,柔性拉绳的另一端与偏转结构相连。本发明通过限位离合器将偏转扭矩传递至偏转结构并带动其偏转,进而拉动柔性拉绳,实现车轮轮宽的压缩,从而有效解决大轮宽刚性车轮转向阻力过大、航天运载体积占用过大、驱动以及转向电机受损时拖拽难度过大等问题。
