The single-degree-of-freedom diameter and width variable wheel type mechanism comprises a center shaft, a center support is rotationally arranged on the center shaft, rotary supporting rods are arranged on the circumferential face of the center support at intervals in the circumferential direction, the rotary supporting rods are hinged to the center support, and connecting pieces are hinged to the ends, away from the center support, of the rotary supporting rods; the ends, far away from the rotary supporting rod, of the connecting pieces are hinged to shear fork assemblies, the shear fork assemblies are connected with the adjacent shear fork assemblies through shear fork supporting connecting pieces, the multiple shear fork assemblies are closed to form a polygonal structure, and the shear fork supporting connecting pieces are hinged to the shear fork assemblies. A supporting rod is hinged to the shear fork supporting connecting piece, and a variable wheel face assembly is hinged to the end, away from the shear fork supporting connecting piece, of the supporting rod. According to the variable wheel type mechanism, single-degree-of-freedom driving is achieved, control is convenient, the wheel face width is changed while the diameter is changed, and adaptability is high.

    本发明提供一种单自由度直径和宽度可变轮式机构,包括中心轴,所述中心轴上转动设有中心支座,所述中心支座的周面沿周向间隔设有旋转支撑杆,所述旋转支撑杆与中心支座铰接,所述旋转支撑杆远离中心支座的一端铰接有连接件,所述连接件远离旋转支撑杆的一端铰接有剪叉组件,所述剪叉组件与相邻剪叉组件之间通过剪叉支撑连接件连接,多个所述剪叉组件之间闭合形成一个多边形结构,所述剪叉支撑连接件与剪叉组件之间铰接,所述剪叉支撑连接件上铰接有支撑杆,所述支撑杆远离剪叉支撑连接件的一端铰接有变轮面组件。该可变轮式机构单自由度驱动,控制方便,直径改变的同时,轮面宽度随之发生改变,适应性强。
