Disclosed is a bicycle variable-transmission-ratio bidirectional driving device. The invention discloses a bicycle variable-transmission-ratio bidirectional driving device. The root of the traction rod 4 is fixed to the middle shaft 17, the traction shaft 6 is fixed to the top of the traction rod 4, the traction ring 8 freely rotates around the traction shaft 6, and one end of the strip-shaped transmission device 1 is connected to the driven wheel 10 after being pulled by the traction ring 8 and is connected to one side of the steering wheel 15 after bypassing the driven wheel 10. The driven wheel 10 drives the rear wheel shaft 14 to rotate clockwise in a one-way mode through the ratchet device 12. The root of the traction rod 5 is fixed to the middle shaft 17, the traction shaft 7 is fixed to the top of the traction rod 5, the traction ring 9 freely rotates around the traction shaft 7, and the other end of the strip-shaped transmission device 1 is connected to the driven wheel 11 after being pulled by the traction ring 9 and is connected to the other side of the steering wheel 15 after bypassing the driven wheel 11. And the driven wheel 11 drives the rear wheel shaft 14 to rotateclockwise in one direction through the ratchet device 13. The root of the crank 2 is fixed with the traction shaft 6, and the root of the crank 3 is fixed with the traction shaft 7.

    自行车变传动比双向驱动装置。本发明公开了一种自行车变传动比双向驱动装置。牵引杆4根部与中轴17固定,牵引轴6固定于牵引杆4顶部,牵引环8绕牵引轴6自由转动,条形传动装置1的一端由牵引环8牵引后连接到从动轮10,绕过从动轮10后链接到转向轮15一侧。从动轮10通过棘轮装置12单向带动后轮轴14顺时针转动。牵引杆5根部与中轴17固定,牵引轴7固定于牵引杆5顶部,牵引环9绕牵引轴7自由转动,条形传动装置1的另一端由牵引环9牵引后连接到从动轮11,绕过从动轮11后链接到转向轮15另一侧。从动轮11通过棘轮装置13单向带动后轮轴14顺时针转动。曲柄2根部与牵引轴6固定,曲柄3根部与牵引轴7固定。
