The invention discloses a novel barrier-free electric wheelchair driving wheel. The novel barrier-free electric wheelchair driving wheel comprises a motor, a chain, a gear, a nut, a multi-ratchet outer sleeve, a triangular fixing frame, a movable frame structure, a reciprocating frame structure and the like. The driving wheel is characterized in that the triangular fixing frame is welded and fixed on a shaft. The triangular fixing frame and the movable frame structure are coaxially connected, the triangular fixing frame is assembled by a multi-ratchet outer sleeve adjacent to the triangular fixing frame, a reciprocating frame structure in the multi-ratchet outer sleeve is matched with a conical locking ring hole in the triangular fixing frame, and a ratchet in the multi-ratchet outer sleeve is connected with a small ratchet in the movable frame structure through a chain. When the driving wheels of the barrier-free electric wheelchair travel on a flat road, barriers exist, and the barrier-free electric wheelch
