The invention discloses a variable-transmission-ratio bidirectional driving device of a bicycle. The roots of the left and right traction rods (5, 4) are fixed with the middle shaft (17), the left and right traction shafts (7, 6) are fixed at the tops of the left and right traction rods (5, 4), and the left and right traction rings (9, 8) freely rotate around the left and right traction shafts (7, 6). One end of the strip-shaped transmission device (1) is connected to the right driven wheel (10) after being dragged by the right dragging ring (8), and is connected to one side of the steering wheel (15) after bypassing the right driven wheel (10), and the other end of the strip-shaped transmission device (1) is connected to the left driven wheel (11) after being dragged by the left dragging ring (9), and is linked to the other side of the steering wheel (15) after bypassing the left driven wheel (11). And the left and right driven wheels (11, 10) unidirectionally drive the rear wheel shaft (14) to rotate clockwise through the left and right ratchet devices (13, 12). And the roots of the left and right cranks (3, 2) are fixed with the left and right traction shafts (7, 6).
一种自行车变传动比双向驱动装置。左右牵引杆(5,4)根部与中轴(17)固定,左右牵引轴(7,6)固定于左右牵引杆(5,4)顶部,左右牵引环(9,8)绕左右牵引轴(7,6)自由转动。条形传动装置(1)的一端由右牵引环(8)牵引后连接到右从动轮(10),绕过右从动轮(10)后连接到转向轮(15)一侧,条形传动装置(1)的另一端由左牵引环(9)牵引后连接到左从动轮(11),绕过左从动轮(11)后链接到转向轮(15)另一侧。左右从动轮(11,10)通过左右棘轮装置(13,12)单向带动后轮轴(14)顺时针转动。左右曲柄(3,2)根部与左右牵引轴(7,6)固定。
