Abstract

A universal wheel driving system includes a sun gear provided to receive power from a power source mounted in a vehicle body, a ring gear to which a wheel is concentrically connected, a gear train engaged to the sun gear and the ring gear and configured to transfer the power between the sun gear and the ring gear while allowing relative motion between the rotation shafts of the sun gear and the ring gear, a carrier supporting a final pinion of the gear train and gear-meshing with the ring gear so that a position of the rotation shaft of the final pinion remains unchanged with respect to a position of the rotation shaft of the ring gear, and a suspension portion provided to support the carrier against the sun gear so that the ring gear and the carrier move up and down with respect to the vehicle body.
