Abstract

본 발명은 자전거 구동장치에 관한 것이다.The present invention relates to a bicycle drive device.

본 발명에 따른 자전거 구동장치는 페달구동을 크랭크축 회전에 기여하는 구간만 수행하도록 하여 효율적으로 자전거를 구동하도록 된 것으로, 체인기어에 림(rim)을 형성하고 크랭크축에 상기 림을 접촉구동하는 구동부와, 회전축의 부시상에 회전자재하게 장착된 제1기어장치를 지니며, 중간기어장치를 통하여 상기 제1기어장치가 연동하는 제2기어장치가 회전축의 일단부에 제공되어 일측의 크랭크축을 시계방향으로 회전시키면 체인기어가 구동됨과 함께 제2기어장치가 반대방향으로 구동되어 반대측 크랭크축이 상승위치로 올라가도록 되어 있으며, 크랭크축들은 100~120°의 범위에서 동작하도록 구성되어 있다.The bicycle driving apparatus according to the present invention is configured to efficiently drive the bicycle by performing only a section contributing to the rotation of the crankshaft, forming a rim on the chain gear and driving the rim on the crankshaft. And a first gear device rotatably mounted on the bush of the rotating shaft, and a second gear device to which the first gear device is interlocked through an intermediate gear is provided at one end of the rotating shaft to provide a crank shaft on one side. When rotated clockwise, the chain gear is driven and the second gear device is driven in the opposite direction so that the opposite crankshaft rises to the ascending position, and the crankshafts are configured to operate in the range of 100 to 120 °.
