【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.
