Description
モータ４４は、自転車１０の推進をアシストする。モータ４４は、電気モータを含む。モータ４４は、いわゆるブラシレスモータである。モータ４４は、図１のペダル３４から後輪３０までの人力駆動力の伝達経路に回転を伝達するように設けられる。モータ４４は、クランク軸４２からフロント回転体３６までの人力駆動力の伝達経路に結合される。図５に示す制御部６０は、基板および駆動回路を含む。駆動回路は、インバータ回路を含み、図１のバッテリ１８からモータ４４に供給される電力を制御する。 The motor 44 assists the propulsion of the bicycle 10. The motor 44 includes an electric motor. The motor 44 is a so-called brushless motor. The motor 44 is provided to transmit the rotation to the transmission path of the manual drive force from the pedal 34 of FIG. 1 to the rear wheel 30. The motor 44 is coupled to the transmission path of the manual drive force from the crankshaft 42 to the front rotor 36. The control unit 60 shown in FIG. 5 includes a substrate and a drive circuit. The drive circuit includes an inverter circuit to control the power supplied from the battery 18 of FIG. 1 to the motor 44.
減速機構５０は、ハウジング４６の内部空間に設けられる。減速機構５０は、モータ４４の出力軸４４Ａの回転速度を減速する。減速機構５０は、モータ４４と出力部５２とを接続する。減速機構５０は、モータ４４の回転を減速して出力部５２に伝達する。減速機構５０は、複数の歯車６８を含む。複数の歯車６８は、第１歯車６８Ａ、第２歯車６８Ｂ、第３歯車６８Ｃ、および、第４歯車６８Ｄを含む。減速機構５０は、回転軸７０をさらに含む。 The speed reduction mechanism 50 is provided in the internal space of the housing 46. The reduction mechanism 50 reduces the rotational speed of the output shaft 44A of the motor 44. The speed reduction mechanism 50 connects the motor 44 and the output unit 52. The reduction mechanism 50 decelerates the rotation of the motor 44 and transmits it to the output unit 52. The reduction mechanism 50 includes a plurality of gear wheels 68. The plurality of gears 68 include a first gear 68A, a second gear 68B , a third gear 68C , and a fourth gear 68D . The speed reduction mechanism 50 further includes a rotating shaft 70.
