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 wheelchair can cross the barriers at the height of the wheels. When a stair is higher than the wheels, the driving wheels of the barrier-free electric wheelchair can lock the triangular fixing frame through differential locks, and the wheels can climb over barriers and directly climb up the stair. Compared with a known intelligent electric wheelchair for climbing stairs, the electric wheelchair has the advantages of flexibility, improved speed, simple and compact structure, low manufacturing cost and the like.
一种新型无障碍电动轮椅车驱动轮。包括电机、链条、齿轮、螺母、多棘轮外套、三角固定架、移动架结构、往复架结构等组成。其特点在轴上有三角固定架焊结固定。三角固定架与移动架结构连接在同轴上三角固定架相邻有多棘轮外套装配,多棘轮外套内中往复架结构与三角固定架内中圆锥锁环孔配合,多棘轮外套内中的棘轮与移动架结构内中的小棘轮有链条联接。本案所述无障碍电动轮椅车驱动轮在平道上行进时有障碍,在车轮高度下可以越障。遇到大于车轮高度楼梯时,无障碍电动轮椅驱动轮可以采用差速锁锁住三角固定架,车轮可以翻越障碍直接爬上楼梯。与公知的智能爬楼梯电动轮椅相比,具有灵活性,提高速度、结构简单紧凑、制造成本低等优点。
