Multi-directional driving mechanism of a spheric wheel

摘要: A multi-directional driving mechanism of a spheric wheel is assembled at preset position on the surface an existing wheel, thus rotation wheel. The comprises least two wheels opposite directions An axle set enter said for via gear. One lateral side abutted tightly onto frictional driving. Rolling elements are pivoted interval periphery and axial direction rolling runs perpendicular to could be normally or sliding without mutual interference.
