The universal wheel assembly comprises an installation support, rolling wheels and an obstacle crossing auxiliary component, a first rotating shaft and a second rotating shaft are arranged on the installation support, the first rotating shaft and the second rotating shaft are perpendicular to each other, and the first rotating shaft is used for being connected with a chassis of the walking equipment; the rolling wheel is roughly spherical and sleeves the second rotating shaft, at least parts of the two sides of the rolling wheel form a plane, the second rotating shaft penetrates through the plane, and the lowest point of the plane is higher than that of the rolling wheel; the obstacle crossing auxiliary component is arranged on the mounting bracket, at least part of the obstacle crossing auxiliary component is located in front of the rolling wheels in the advancing direction of the universal wheel assembly, and the lowest point of the obstacle crossing auxiliary component is not higher than the lowest point of the plane. When the rolling wheel passes through an obstacle higher than the lowest point of the plane, the obstacle crossing auxiliary component enables the rolling wheel to smoothly cross the obstacle by increasing the height of the rolling wheel and improving the spherical flexibility of the rolling wheel, and the problem that the rolling wheel is possibly blocked due to the plane is effectively avoided.
本发明公开一种万向轮组件及行走设备,包括安装支架、滚动轮与越障辅助部件,其中,安装支架上设有第一转轴与第二转轴,第一转轴与第二转轴相互垂直,第一转轴用于与行走设备的底盘连接;滚动轮大致呈球形并套设于第二转轴,滚动轮的两侧至少部分构造为平面,第二转轴穿设于平面,且平面的最低点高于滚动轮的最低点;越障辅助部件设于安装支架,在万向轮组件的行进方向上越障辅助部件至少部分位于滚动轮的前方,越障辅助部件的最低点不高于平面的最低点。滚动轮在经过高于平面最低点的障碍物时,越障辅助部件通过提高滚动轮的高度以及滚动轮呈球形的灵活性,从而使滚动轮可以较顺畅地越过障碍物,有效地避免了平面可能导致滚动轮抵死的问题。
