    • A freewheel assembly (1) for a rear wheel of a bicycle includes a body (10), a sprocket wheel (12) mounted on the body (10), a sleeve (16) sandwiched between the body (10) and the sprocket wheel (12), a plurality of roller bearings (11) fitted between the sleeve (16) and the sprocket wheel (12), a disk clamp (15) fitted to a distal end of the body (10) and clamping the sprocket wheel (12) to the body (10), and pluralities of first and second ball bearings (13, 14) to ensure correct location of the sprocket wheel (12) and roller bearings (11). In a driving mode of the freewheel assembly (1), the roller bearings (11) engage the sprocket wheel (12) to the body (10). In a non-driving mode, the roller bearings (11) separate from sprocket wheel (12) to allow the body (10) to rotate while the sprocket wheel (12) does not rotate.

    • An indexed gear-shift mechanism for a bicycle that has one lever for up-shifting and another lever for down-shifting. A ratchet wheel is fixed to the down-shifting lever and has two rows of teeth along an outer curvature thereof. A pair of pawls are placed on the up-shifting lever and works in conjunction with the two rows of teeth. A pair of springs respectively apply force on the levers in a counterclockwise direction. When a rider applies a force on the up-shifting lever in a clockwise direction, the pawls move to a next adjacent pair of teeth, one pawl preventing rotation of the lever and the other pawls preventing rotation of the ratchet wheel; the bicycle is in a higher gear. When a rider applies a force on the down-shifting lever in a clockwise direction, the pawls move to a previous adjacent pair of teeth, but the pawls do not prohibit movement of the down-shifting lever; therefore, the ratchet wheel may be down-shifted through as many gears as desired in one action.
    • 一种用于自行车的分度变速机构,其具有用于上移的一个杆和用于向下换档的另一杆。 棘轮固定在下移杆上,沿其外曲面具有两排齿。 一对棘爪放置在上移杆上,与两排牙齿配合使用。 一对弹簧分别在逆时针方向上对杆施加力。 当骑乘者沿顺时针方向对升档杆施加力时,棘爪移动到下一个相邻的一对齿,一个棘爪防止杠杆的旋转,另一个棘爪阻止棘轮旋转; 自行车处于较高档位。 当骑手沿顺时针方向向下移动杆施加力时,棘爪移动到先前相邻的一对齿,但是棘爪不禁止下移杆的移动; 因此,棘轮可以在一个动作中根据需要向下移动通过尽可能多的档位。

    • An improved form of bicycle speed change mechanism, characterized in that, a speed change support is installed to sustain and keep a bicycle chain at a fixed tension; a stop ring installed on the speed change support is bent to one side to form a positioning plate that is bent outwardly; a C-type snap ring is inserted in the gap of a support shaft; one end of the C-type snap ring extends outwardly to form a handle; one end of the handle forms a horizontal plate on which two guide holes are formed; two bolts are mounted in the guide holes; adjustment of the length of the two bolts extruding from the guide holes of the horizontal plate controls the angle of rotation of the stop ring wtih respect to the baffle angle of the bicycle frame, and consequently changes the force produced by the torsion spring which is dragged by the stop ring.
    • 一种改进形式的自行车变速机构,其特征在于,安装变速支架以维持和保持自行车链条处于固定张力; 安装在变速支架上的止动环弯曲到一侧以形成向外弯曲的定位板; C形卡环插入支撑轴的间隙中; C型卡环的一端向外延伸以形成手柄; 手柄的一端形成水平板,其上形成有两个导孔; 两个螺栓安装在导孔中; 调整从水平板的引导孔挤出的两个螺栓的长度控制止动环的旋转角度相对于自行车车架的挡板角度,从而改变被拖动的扭转弹力产生的力 通过停止环。
