The invention provides a freely-rotating electrically-driven universal wheel which comprises a wheel bridge, a wheel set composed of two electric wheels is installed on the two sides of the wheel bridge through a balance mechanism, the top of the wheel bridge is rotationally connected with a connecting rod outer sleeve by embedding an eccentric first bearing, a connecting rod fixed to the wheel bridge is fixedly connected into the first bearing in a sleeved mode, a communication conductive part and a power supply conductive part are installed on the outer side of the connecting rod, and an electronic gyroscope is installed in the wheel bridge. The connecting rod is in running fit in the outer sleeve, so that the central shaft of the electric wheel set eccentrically rotates around the axis of the connecting rod, the universal wheel has a flexible steering (passive steering) function in the use process, and a power supply and communication wire in the universal wheel passes through the hollow connecting rod and then is connected with a control panel. Due to the fact that the wheel bridge and the connecting rod are in follow-up motion, and the communication conductive part and the power supply conductive part of the universal wheel can be an annular electrode or a secondary coil, the problems of wire winding and wire breakage do not exist.

    本发明提供一种自由转动电驱动万向轮,包括轮桥,轮桥的两侧通过平衡机构安装有两个电动轮组成的轮组,轮桥顶部通过嵌设偏心的第一轴承转动连接有连杆外套,第一轴承的内部固定套接有和轮桥固定的连杆,连杆的外侧安装有通讯导电部和供电导电部,轮桥的内部安装设有电子陀螺仪。本发明连杆在外套内的转动配合,使电动轮组中心轴绕连杆轴线进行偏心转动,使得万向轮在使用过程中具备灵活的转向(被动转向)功能,其中万向轮内部的供电和通讯电线经中空的连杆内部通过,再和控制板连接,由于轮桥和连杆是随动的,而且万向轮的通讯导电部以及供电导电部可以选用环状电极或者次级线圈,所以不会有导线缠绕以及导线断裂的问题。
