如图2所示，所述轮圈1包括左圈1a及右圈1b，所述左圈1a与所述右圈1b同轴设置且通过若干螺栓固定连接。通过将所述轮圈1设置为左圈1a及右圈1b组合的形式，既能方便地对所述轮圈1进行加工，又能方便安装所述轮片组件2，提高组装的便利性。
与现有技术相比，本申请通过设置轮片支架22，将所述轮片支架22设置于所述轮圈1上，又在所述轮片支架22的一侧设置安装轴221及对接轴222，另一侧设置对接孔223，通过将相邻两所述轮片支架22的其中一者的所述对接轴
222套接于另一者的所述对接孔223内，从而使得所述轮片支架22围绕所述轮圈1的中心轴周向地布置。又在所述轮片支架22上一一对应地设置轮片21，使得所述轮片21围绕所述轮圈1的中心轴周向地布置，因此，这些轮片21共同组成了一个车轮整体，使整个万向轮达到围绕所述轮圈1的中心轴前后滚动的目的。另外，由于所述轮片21利用所述轴承23设置于所述轮片支架22，因此，每一轮片21均可围绕所述安装轴221单独滚动，使整个万向轮实现左右滚动的目的。因而，本申请可以进行多向滚动，转向灵活，而且，只需要将所述轮片21、轴承23及轮片支架22组装成一轮片组件2，再将多个轮片组件2设置于所述轮圈1上即可，零件少，结构简单、紧凑，且组装十分方便。
以上所揭露的仅为本申请的较佳实例而已，当然不能以此来限定本申请之权利范围，因此依本申请所申请专利范围所作的等同变化，仍属于本申请所涵盖的范围。
