The invention relates to a self-adaptive obstacle-crossing deformation wheel which comprises a deformation wheel body composed of a plurality of arc-shaped wheel strips distributed in the circumferential direction, a center supporting hub and a spoke mechanism, the spoke mechanism comprises fixed spokes and deformation arms which are in one-to-one correspondence with the arc-shaped wheel strips, one ends of the fixed spokes are fixed to the center supporting hub, and the other ends of the fixed spokes are fixed to the center supporting hub. One end of each arc-shaped wheel strip is hinged to the center supporting hub, the other end of each arc-shaped wheel strip is hinged to the middle of the corresponding arc-shaped wheel strip, the hinged portion of each arc-shaped wheel strip extends in the radial direction to form a first arm plate of a deformation arm, linear sliding grooves are formed in second arm plates of the deformation arms, transverse pin shafts inserted into the linear sliding grooves are arranged on the first arm plates, and a center disc body connected with the second arm plates is rotationally matched with the center supporting hub. The deformation arms coincide with the sides of the fixed spokes when folded into a straight line, the deformation wheel body is in a wheel type state, and the center supporting hub is provided with stopping pieces for stopping the deformation arms to limit deformation of the deformation arms on the same side in the circumferential direction. The device automatically adapts to the obstacle condition to automatically adjust the deformation state, and has the advantages of being simple in structure and convenient to use.
本发明涉及一种自适应式越障变形轮,包括由若干沿周向分布的圆弧形轮条构成的变形轮体、中心支撑轮毂及轮辐机构,轮辐机构包括与圆弧形轮条一一对应的固定辐条及形变臂,固定辐条一端固定于中心支撑轮毂上,另一端铰接于圆弧形轮条中部,每根圆弧形轮条的铰接部沿径向延伸形成形变臂的第一臂板,形变臂的第二臂板上设有直线滑槽,第一臂板上设有插置于直线滑槽内的横向销轴,中心支撑轮毂上转动配合有连接各第二臂板的中心盘体,形变臂折叠成直线状时重合于固定辐条侧方且变形轮体为轮式状态,中心支撑轮毂设有止挡形变臂以限制形变臂沿周向同一侧形变的止挡件。自动适应障碍物情况实现自动调整变形状态,具有结构简单和使用方便的优点。
