申请内容
本申请的目的在于提供一种转向灵活、结构简单、组装方便的滚轮支撑式多片万向轮。
为了实现上述目的，本申请提供的滚轮支撑式多片万向轮包括轮圈、支撑环、多个轮片以及多个滚轮，所述轮片可转动地套于所述支撑环，且所述轮片围绕所述轮圈的中心轴呈周向地布置于所述轮圈外周，所述支撑环与所述轮圈呈同心地设置；所述滚轮枢接于所述轮圈的内部两侧，且所述滚轮与所述轮片的外周滚动接触。

具体地，所述滚轮支撑式多片万向轮还包括滚轮支架，所述滚轮支架围绕所述轮圈的中心轴呈周向地安装于所述安装槽内。通过设置所述滚轮动架，使得所述滚轮组装更加容易方便。
较佳地，所述滚轮支撑式多片万向轮还包括定位支架，所述定位支架设置于两相邻的所述轮片之间，以对所述轮片轴向定位。这样可以防止所述轮片沿所述支撑环的中心轴方向发生位置移动，从而提高万向轮结构的稳定性以及运行的安全性。
具体地，所述滚轮支撑式多片万向轮还包括轴承，所述轴承套于所述支撑环及所述轮片之间，两相邻的所述定位支架之间抵顶所述轴承的内圈。设置所述轴承可以使得所述轮片更稳定流畅地转动。

具体实施方式
为详细说明本申请的技术内容、构造特征、所实现的效果，以下结合实施方式并配合附图详予说明。
如图1至图5所示，本申请的滚轮支撑式多片万向轮100包括轮圈1、支撑环2、多个轮片3以及多个滚轮4，所述轮片3的横截面呈圆环形，所述轮片3可转动地套于所述支撑环2，且所述轮片3围绕所述轮圈1的中心轴呈周向地布置于所述轮圈1外周，所述支撑环2与所述轮圈1呈同心地设置；所述滚轮4枢接于所述轮圈1的内部两侧，且所述滚轮4与所述轮片3的外周滚动接触。所述滚轮4围绕所述轮圈1的中心轴周向设置。所述轮片3及所述滚轮4的中心轴均与所述轮圈1的中心轴垂直。
请参阅图6及图7，所述轮圈1的外侧周向凹陷地设有安装槽1a，所述滚轮4及所述轮片3设置于所述安装槽1a内。所述安装槽1a可以容纳所述支撑环2以及所述轮片3的一部分，从而既可以只露出轮片3的另一部分而隐藏不必要的零件，提高万向轮的美观性，又可以使得整个万向轮的体积更小，结构更加紧凑合理。具体地，所述滚轮支撑式多片万向轮100还包括滚轮支架5，所述滚轮支架5围绕所述轮圈1的中心轴呈周向地安装于所述安装槽1a内。通过设置所述滚轮4动架，使得所述滚轮4组装更加容易方便。所述滚轮支架5的下端 套接固定于所述轮圈内的固定柱上，所述滚轮支架5的上端向所述轮片3安装槽1a的两侧延伸出两分叉51，所述分叉51上设有枢接轴52，所述滚轮4枢接到所述枢接轴52上。此外，为了适应所述轮片3围成的圆形的结构并且使滚轮4能更好地与轮片3滚动接触，可以使所述枢接轴52设置成直线形，并在一所述枢接轴52上枢接多个滚轮4，本实施例一所述枢接轴52枢接有三个滚轮4，其中位于两侧的滚轮4的表面为圆弧形，以适应所述轮片3。另外，还可以将所述枢接轴52设置成弧形或弯折结构，从而使得每个滚轮4的表面都能与对应的轮片3的表面完全接触，以使滚动更平稳。
再如图4及图5所示，所述滚轮支撑式多片万向轮100还包括定位支架6及轴承7，所述定位支架6设置于两相邻的所述轮片3之间，以对所述轮片3轴向定位。这样可以防止所述轮片3沿所述支撑环2的中心轴方向发生位置移动，从而提高万向轮结构的稳定性以及运行的安全性。所述轴承7套于所述支撑环2及所述轮片3之间，两相邻的所述定位支架6之间抵顶所述轴承7的内圈。设置所述轴承7可以使得所述轮片3更稳定流畅地转动。更具体地，所述定位支架6的相对两侧分别延伸出轴套，所述轴套抵顶于与其位于同侧的所述轴承7的内圈。
再请参阅图5，所述轮片3包括内轮31及外轮套32，所述外轮套32套接固定于所述内轮31的外周。所述内轮31的表面外周周向设有定位肋311，所述外轮套32的内壁周向设有卡槽321，所述卡槽321与所述定位肋311卡合。这样可以使所述外轮套32与所述内轮31能相对固定，提高连接的稳定性。所述外轮套32可以使用稍软且耐磨的材料制成，例如橡胶材料；所述内轮31可以使用硬度较高的材料制成，例如铝合金材料。
再如图2及图6所示，所述轮圈1包括左圈11及右圈12，所述左圈11与所述右圈12通过螺栓同轴固定连接。通过将所述轮圈1设置为左圈11及右圈12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3及滚轮4，提高组装的便利性。
在本实施例中，所述定位支架6、轴承7及所述轮片3的数量均为48个，相邻两轮片3或相邻两定位支架6之间的圆心角为7.5度。当然，所述轮片3或 所述定位支架6的数量也可以为更少或更多，本领域技术人员可以通过所述轮片3或定位支架6的数量以及万向轮半径计算出相邻两轮片3之间的圆心角度，进而可以计算出所述定位支架6的两轴套的长度，在此不再详细说明。
与现有技术相比，本申请通过将轮片3套接于支撑环2上，又将轮片3周向地布置于所述轮圈1的外周，使得所述支撑环2与所述轮圈1同心，同时设置滚轮4，并使所述滚轮4枢接于所述轮圈1的内部两侧；利用所述滚轮4与所述轮片3滚动接触，一方面可以使得所述轮片3及所述支撑环2能稳定地支承于所述轮圈1的外周，从而使这些轮片3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；另一方面可以使各个所述轮片3能稳定流畅地围绕自身的中心轴转动，从而能使万向轮实现左右滚动的目的。因此，本申请可以进行多向滚动，转向灵活，而且，零件组合少，结构简单、紧凑，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，因此依本申请专利范围所作的等同变化，仍属于本申请所涵盖的范围。
