Abstract

체인 휠의 외측부에서 베어링 블록내에 체결되며, 자전거의 하부 브래킷 액슬내에 편심 체결된 커넥터상에 장착된 볼 베어링의 측부 돌출부와 연결되는 크랭크를 구비하는 자전거체인 전동장치에 관한 것으로, 여기에서 폐달을 밟는데 드는 에너지 소비를 최소화하기 위해 볼 베어링을 편심 회전시키고 크랭크의 힘의 아암을 자동 변화시키기 위해 상기 커넥터가 회전한다.A bicycle chain transmission comprising a crank which is fastened in a bearing block at the outside of the chain wheel and connected to the side projection of a ball bearing mounted on an eccentrically fastened connector in the lower bracket axle of the bicycle, wherein The connector rotates to eccentrically rotate the ball bearings and to automatically change the arm of the crank's force to minimize energy consumption.
