【0001】[0001]
本考案は二輪自転車に係り、特に、二輪自転車の前輪に後輪の回転を伝動して 前輪を後輪と同期して回転させる二輪自転車の前輪後輪同期伝動機構に関する。 The present invention relates to a two-wheeled bicycle, and more particularly to a front-wheel-rear-wheel synchronous transmission mechanism for a two-wheeled bicycle that transmits rotation of a rear wheel to a front wheel of the two-wheeled bicycle and rotates the front wheel in synchronization with the rear wheel.
【0002】[0002]
従来の二輪自転車は、ペダルを踏むと後輪だけが回転する構成である。前輪に は、回転駆動力は伝わらない。 The conventional two-wheeled bicycle has a structure in which only the rear wheels rotate when the pedal is depressed. No rotational drive force is transmitted to the front wheels.
【0003】[0003]
前輪が回転駆動されないため、特に、コーナを曲がるとき、平坦でない道、湿 地、又は滑り易い道を走行する場合に、前輪がつまずいて二輪自転車は転倒し易 かった。 そこで、本考案は、上記課題を解決した二輪自転車の前輪後輪同期伝動機構を 提供することを目的とする。 Since the front wheels are not driven to rotate, the front wheels stumble and the two-wheeled bicycle is prone to tipping, especially when traveling on uneven roads, wetlands, or slippery roads when cornering. Therefore, an object of the present invention is to provide a front wheel / rear wheel synchronous transmission mechanism for a two-wheeled bicycle that solves the above-mentioned problems.

図1は本考案の一実施例になる二輪自転車を示す。二輪自転車の前輪3と後輪 4とには夫々伝動機構1a,1bが設けてある。後輪4の伝動機構1aと前輪3 の伝動機構1bとは、軟らかいシャフト2でもって連結してある。これによって 、前輪3は後輪4と同期に伝動される。 FIG. 1 shows a two-wheeled bicycle according to an embodiment of the present invention. The front wheel 3 and the rear wheel 4 of the two-wheeled bicycle are provided with transmission mechanisms 1a and 1b, respectively. The transmission mechanism 1a of the rear wheel 4 and the transmission mechanism 1b of the front wheel 3 are connected by a soft shaft 2. As a result, the front wheels 3 are transmitted in synchronization with the rear wheels 4.
【0006】 図2(A),(B)に示すように、伝動機構1a(1b)は、取付け盤10を 有する。取付け盤10には、伝動盤11がリベットで固定してある。伝動盤11 には、適当な数の伝動穴110が形成してある。伝動穴110には、伝動ギヤ1 2の歯120が噛合する。 図3に示すように、伝動ギヤ12の歯120が伝動穴110と噛合すると、動 力の伝動の方向が90度転換される。また、ケーシング13内には、伝動ギヤ1 2が固定してある回転軸20と回転軸21とが夫々軸受15、16によって回転 可能に支持されている。回転軸20、21にはギヤ172、171が固定してあ り、ギヤ171、172は噛合している。ギヤ172、171は、回転軸20か ら回転軸21へ伝達する回転を減速する減速ギヤ機構17を構成する。ギヤ17 1は、最終の減速ギヤである。回転が減速されるので、回転軸20から回転軸2 1への回転の伝達は円滑になされる。回転軸21のケーシング13外に突き出て いる部分と軟らかいシャフト2の端とが、リングカップリング14によって連結 してある。As shown in FIGS. 2A and 2B, the transmission mechanism 1 a (1 b) has a mounting board 10. A transmission plate 11 is fixed to the mounting plate 10 with rivets. An appropriate number of transmission holes 110 are formed in the transmission board 11. The teeth 120 of the transmission gear 12 mesh with the transmission hole 110. As shown in FIG. 3, when the teeth 120 of the transmission gear 12 mesh with the transmission holes 110, the direction of power transmission is changed by 90 degrees. Further, in the casing 13, a rotary shaft 20 and a rotary shaft 21 to which the transmission gear 12 is fixed are rotatably supported by bearings 15 and 16, respectively. Gears 172 and 171 are fixed to the rotary shafts 20 and 21, and the gears 171 and 172 mesh with each other. The gears 172 and 171 configure a reduction gear mechanism 17 that reduces the rotation transmitted from the rotary shaft 20 to the rotary shaft 21. The gear 171 is the final reduction gear. Since the rotation is decelerated, the rotation is smoothly transmitted from the rotary shaft 20 to the rotary shaft 21. A portion of the rotary shaft 21 projecting outside the casing 13 and the end of the soft shaft 2 are connected by a ring coupling 14.
【0007】 軟らかいシャフト2の一端が後輪4の伝動機構1aと連結してあり、軟らかい シャフト2の他端が前輪3の伝動機構1bと連結してある。後輪4の伝動機構1 aは取付け盤10によって後輪4に設けてある。前輪3の伝動機構1bは取付け 盤10によって前輪3に設けてある。後輪4及び前輪3が夫々伝動機構1a,1 bを有する。One end of the soft shaft 2 is connected to the transmission mechanism 1 a of the rear wheel 4, and the other end of the soft shaft 2 is connected to the transmission mechanism 1 b of the front wheel 3. The transmission mechanism 1a of the rear wheel 4 is provided on the rear wheel 4 by the mounting board 10. The transmission mechanism 1b of the front wheel 3 is provided on the front wheel 3 by the mounting board 10. The rear wheel 4 and the front wheel 3 have transmission mechanisms 1a and 1b, respectively.
【0008】 二輪自転車を走行させているときに、ペダルを踏むと後輪4が回転する。後輪 4と一体に、取付け盤10と伝動盤11とが回転する。伝動盤11の回転が伝動 ギヤ12に伝達し、減速ギヤ機構17で回転速度が減速され、減速された回転が リングカップリング14及び軟らかいシャフト2を介して前輪3の伝動機構1b に伝達される。ここで、前輪3の伝動機構1bは、後輪4の伝動機構1aと同じ であり、回転の伝達の方向が異なるだけであり、前輪3の伝動盤11の伝動穴1 10の数は後輪4の伝動盤11の伝動穴110の数と等しい。よって、前輪3は 、後輪4と同期して回転する。When the pedal is stepped on while the two-wheeled bicycle is running, the rear wheel 4 rotates. The mounting board 10 and the transmission board 11 rotate integrally with the rear wheel 4. The rotation of the transmission plate 11 is transmitted to the transmission gear 12, the rotation speed is reduced by the reduction gear mechanism 17, and the reduced rotation is transmitted to the transmission mechanism 1b of the front wheel 3 via the ring coupling 14 and the soft shaft 2. . Here, the transmission mechanism 1b of the front wheel 3 is the same as the transmission mechanism 1a of the rear wheel 4, only the direction of rotation transmission is different, and the number of the transmission holes 110 of the transmission plate 11 of the front wheel 3 is equal to the number of the rear wheels. It is equal to the number of the transmission holes 110 of the transmission plate 11 of 4. Therefore, the front wheels 3 rotate in synchronization with the rear wheels 4.
【0009】 前輪3は積極的に回転することによって、コーナを曲がるとき、平坦でない道 、湿地、又は滑り易い道を走行する場合でも、つまずくことが起きず、よって二 輪自転車は転倒し難い状態で運転される。 なお、伝動盤11の伝動穴110にはごみ、ちり等が付着していない。よって 、後輪4についての伝動盤11から伝動ギヤ12への回転の伝達、及び前輪3に ついての伝動ギヤ12から伝動盤11への回転の伝達は共に円滑になされ、故障 が起きる虞れはない。When the front wheel 3 positively rotates, the front wheel 3 does not stumble even when traveling on an uneven road, a wetland, or a slippery road when turning a corner, so that the two-wheeled bicycle is hard to fall down. Be driven in. It should be noted that dust, dust, etc. are not attached to the transmission holes 110 of the transmission plate 11. Therefore, the transmission of the rotation of the rear wheel 4 from the transmission plate 11 to the transmission gear 12 and the transmission of the rotation of the front wheel 3 from the transmission gear 12 to the transmission plate 11 are both smoothly performed, and there is a possibility that a failure may occur. Absent.
