従来の電動自転車はバッテリーの電力によってモータから動力が出力され、登 り坂でオートバイのように後輪を駆動させ、楽に走行することができる。 In conventional electric bicycles, power is output from the motor by the power of the battery, You can easily drive by driving the rear wheels like a motorcycle on a slope.
【0003】[0003]
しかしながら、従来の電動自転車の伝動装置は、そのモータが下パイプとシー トポストとの間に設置され、複雑なギア組み及び大ギアを介して後輪を駆動させ るので、体積が大きく、部材が多く、更に組合することも非常に面倒であり、尚 、伝動装置に設置する感知装置の精確性も不足である。 However, in a conventional electric bicycle transmission, its motor is It is installed between the topo and drive the rear wheels through a complicated gear set and a large gear. Therefore, the volume is large, there are many members, and it is very troublesome to combine them. The accuracy of the sensing device installed in the transmission is also insufficient.
【0004】 例えば、台湾実用新案登録第498876号の「電動自転車の伝動装置」は、 スピードセンサー及びクランク軸に設置する第二ギアを介して、第二ギアのスピ ンが遅くなる際、走行動力の不足と判断して、他のセンサーからモータに出力信 号を伝送すると共に、後輪を駆動させる。しかし、乗用者は楽にペダルを踏み、 ゆっくり走行する場合、スピードセンサーが走行動力の不足と判断するにより、 動力を出力するというミス判断を発生してしまうことがある。[0004] For example, Taiwan Utility Model Registration No. 489876 "Electric bicycle transmission" is The speed of the second gear is set via the speed sensor and the second gear installed on the crankshaft. When the speed becomes slow, it is judged that the running power is insufficient and other sensors output signals to the motor. The signal is transmitted and the rear wheels are driven. However, passengers can easily pedal When traveling slowly, the speed sensor determines that running power is insufficient, A mistaken decision to output power may occur.
【0005】 そこで、案出されたのが本考案であって、小体積を有すると共に、感知精確の 特徴を有する電動自転車の伝動装置を提供することを目的としている。[0005] Therefore, the present invention was devised, which has a small volume and is capable of sensing and An object of the present invention is to provide a transmission device of an electric bicycle having the characteristics.
