Universal wheel device

The utility model discloses a universal wheel device which comprises a casing, a transition plate, a rotation motor, a driving motor, a rotating body, a wheel, a cover plate, a rotating transmission mechanism and a driving transmission mechanism. The rotation motor is installed on the transition plate, the transition plate is fixed at the position of a notch positioned at the upper end of the casing, the driving motor is fixed on a large gear of the rotating transmission mechanism, the wheel is installed between the rotating body and the cover plate, the rotation motor drives the rotating body to rotate through the rotating transmission mechanism so as to achieve steering of the wheel device; the driving motor drives the wheel to move through the driving transmission mechanism to achieve advance or retreat of the wheel device; and universal movement of the wheel device is achieved through the rotation motor and the driving motor jointly. The universal wheel device is simple in structure and convenient to use, steering movement and driving movement can be performed synchronously, and working efficiency of robots or other devices borne by the universal wheel device is effectively improved.
