摘要： 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.

摘要： A universal wheel driving system includes a sun gear provided to receive power from a power source, a ring gear provided so that a rotation axis thereof is moved relative to a rotation axis of the sun gear and a wheel is concentrically connected to the ring gear, at least one gear train engaged to the sun gear and the ring gear and configured to allow relative motion between the rotation axes of the sun gear and the ring gear and to form a continuous power transmission state therebetween, a carrier constantly supporting a position of a rotation axis of a final pinion of the at least one gear train with respect to a position of the rotation axis of the ring gear, and a suspension portion configured to support the carrier to be movable upward and downward with respect to a vehicle body.
