Next, the driving member 30 is installed at a bias position shifted from the center below the inner surface of the driven member 20 so that the external tooth surface 31 of the driving member 30 meshes with the gear internal tooth surface 21. Furthermore, two interlocking members 40 are installed from both sides with the driven member 20 interposed therebetween, and the two interlocking members 40 are aligned with the through holes 42 between the second bearings 421 formed in the disk portions 40a of the interlocking members 40 so as to match the shaft 32.

次に図５および図６を参照しながら、本考案の自転車用の駆動力伝動機構の動作を説明する。
大径の歯車円板６７が自転車のペダルによって回転され、チェーンベルト６５が移動すると、それにより後輪６１のフライホイール６３が駆動付勢される。前記駆動部材３０のシャフト３２がこの付勢されたフライホイール６３と同期回転駆動し、駆動部材３０の外歯歯面３１が被駆動部材２０の歯車用内歯面２１に噛み合って移動し、後輪６１を前方に移動すると共に歯車用内歯面２１の上方へと移動する力が発生する。
Next, the operation of the driving force transmission mechanism for a bicycle according to the present invention will be described with reference to FIGS.
When the large-diameter gear disc 67 is rotated by the bicycle pedal and the chain belt 65 is moved, the flywheel 63 of the rear wheel 61 is driven and biased. The shaft 32 of the drive member 30 is driven to rotate synchronously with the biased flywheel 63, and the external tooth surface 31 of the drive member 30 is engaged with the internal gear tooth surface 21 of the driven member 20 and moves. A force is generated that moves the wheel 61 forward and moves the wheel 61 above the internal gear tooth surface 21.
被駆動部材２０の中心からずれた偏倚位置に駆動部材が配設されたオフセット歯車機構によって、自転車６０の重量及び負荷の重力を担持している駆動部材３０が、自転車のペダル回動に伴うチェーンベルト６５による駆動力との相乗効果により歯車用内歯面２１を前方及び上下方向へ移動する結果、被駆動部材２０の相対回転運動を発生し、これにより重力を効果的に動的駆動力に変換し、自転車の必要駆動力の出力条件を軽減して、楽に自転車を走行することができる。 Due to the offset gear mechanism in which the driving member is disposed at a biased position deviated from the center of the driven member 20, the driving member 30 carrying the weight and the load gravity of the bicycle 60 is connected to the chain due to the rotation of the bicycle pedal. As a result of moving the gear internal tooth surface 21 forward and vertically by a synergistic effect with the driving force of the belt 65, a relative rotational motion of the driven member 20 is generated, thereby effectively converting gravity into a dynamic driving force. By converting, the output condition of the required driving force of the bicycle can be reduced, and the bicycle can be run easily.
図６に示すように、駆動部材３０が回転運動中にスピードアップして、駆動力を増大すると、駆動部材３０の外歯歯面３１が歯車機構で前方及び上方へ移動させられ、被駆動部材２０の重力中心点が相対的に前方及び下方へ移動させられ、自動的に後輪６１を回転し、これにより、自転車６０を前方へ移動することができる。 As shown in FIG. 6, when the driving member 30 speeds up during the rotational movement and the driving force is increased, the external tooth surface 31 of the driving member 30 is moved forward and upward by the gear mechanism, and the driven member is moved. The center of gravity 20 is relatively moved forward and downward, and automatically rotates the rear wheel 61, whereby the bicycle 60 can be moved forward.
一方、駆動部材３０と共に上方へ持ち上げられた後輪６１の上，下方フォーク部６４，６５は、自転車６０の後輪ブラケットを僅かに持ち上げることになる。その結果、被駆動部材２０の両側方に配置されている制限ユニット５０の制限シャフト５１が旋回用穴５１１を介して旋回ロッド５３に沿って降下してきて，駆動部材３０とは反対の直線運動を産出する。そして、駆動部材３０の回転及び制限シャフト５１によって付勢された連動部材４０の第１軸受４１が被駆動部材２０の環状座に沿って滑らかに回転する。駆動部材３０及び制限シャフト５１が移動して、各々の制限位置まで、駆動部材３０が上昇して制限シャフト５１が下降すると、底部に係合されている制限ナット５３４によって制限シャフト５１が、駆動部材３０の上方移動および重力によるオフセット重力相乗歯車運動を停止して、制限効果を達成し、確実に駆動部材３０が被駆動部材２０の円盤部４０ａ中心線上の反対側へ移動しないようになっている。 On the other hand, the upper and lower forks 64 and 65 of the rear wheel 61 lifted upward together with the drive member 30 slightly lift the rear wheel bracket of the bicycle 60. As a result, the restricting shafts 51 of the restricting units 50 arranged on both sides of the driven member 20 descend along the turning rod 53 through the turning holes 511, and perform a linear motion opposite to the driving member 30. To produce. Then, the first bearing 41 of the interlocking member 40 urged by the rotation of the driving member 30 and the restriction shaft 51 smoothly rotates along the annular seat of the driven member 20. When the driving member 30 and the restriction shaft 51 move and the driving member 30 moves up to the respective restriction positions and the restriction shaft 51 descends, the restriction shaft 51 is moved by the restriction nut 534 engaged with the bottom portion. By stopping the upward movement of the 30 and the offset gravity synergistic gear movement due to gravity, a limiting effect is achieved, and the driving member 30 is reliably prevented from moving to the opposite side on the center line of the disk portion 40a of the driven member 20. .
前記駆動部材３０への駆動力が停止されたり軽減されると、駆動部材３０の外歯歯車３１が被駆動部材２０の歯車用内歯面２１に沿って下降するようになる。
一方、制限ユニット５０の制限シャフト５１は旋回用穴５１１を介して旋回ロッド５３に沿って上昇して、減衰ばね５２に規制されて、自転車６０の衝撃吸収効果を促進する。
When the driving force to the driving member 30 is stopped or reduced, the external gear 31 of the driving member 30 descends along the internal gear tooth surface 21 of the driven member 20.
On the other hand, the restricting shaft 51 of the restricting unit 50 rises along the turning rod 53 via the turning hole 511 and is restricted by the damping spring 52, thereby promoting the shock absorbing effect of the bicycle 60.
