The present invention relates to an acceleration power transmission device of a bicycle. The bicycle comprises: a pedal (11) connected to a pair of left and right crank arms (12), a pedal central shaft (13) coupled to the pair of left and right crank arms, and a rotor (16) and a pedal side stator (15) engaging with the pedal central shaft: a power transmission system including a plurality of planetary gears (21) located above a hollow of the pedal central shaft, a ring gear (22), a planetary gear carrier (23), a pin hole (24), and a planetary gear combination concentric disc (25); a sun gear (31) which is located in the hollow of the pedal central shaft (13), and is engaged with the planetary gear to obtain an acceleration output, and a chain ring (33) connected and coupled to a protrusion (32) of the sun gear and connecting power to a rear wheel shaft via a chain; a first acceleration power drive device composed of a cylindrical hub (41) which is provided with a gear teeth formed therein and acts as a ring gear of an acceleration power device, a stator provided at a predetermined distance from the inside of the cylinder, and a fixture/support to fix and support on a bicycle frame; and a second acceleration power drive device consisting of a rear wheel hub (54), a rear wheel central shaft (55), a one-way power transmission device (57), a permanent magnet (51) and a rear wheel-side stator (52), and a rotor (53) on a rear wheel drive side.

    본 발명은 자전거의 가속 동력전달장치에 관한 것으로 좌우한쌍의 크랭크암(12)에 연결된 페달(11)과 좌우한쌍의 크랭크암에 결합하는 폐달중심축(13) 페달중심축과 치합하는 페달측고정자(15),회전자(16): 폐달중심축 중공상에 위치하는 다수의 유성기어(21), 링기어(22), 유성기어 캐리어(23), 핀공(24), 유성기어를 결합시키는 유성기어조합 동심원판(25)으로 구성된 동력변속장치; 폐달중심축(13) 중공상에 위치하여 유성기어와 치합결속되어 가속출력을 얻는 태양기어(31)와 태양기어의 돌출부분(32)과 연결결합되어 뒷바퀴축에 체인을 매개로 동력을 연결시키는 체인링(33 ); 원통안쪽에 기어산이 만들어져 가속동력장치의 링기어 역할, 원통안쪽에 일정거리 이격되어 설치되는 고정자역할 및 자전거 프레임에 고정·지지 역할을 하는 원통허브(41)로 이뤄진 제1가속동력구동장치. 후륜구동측에 후륜허브(54), 후륜중심축(55), 한방향동력전달장치(57),영구자석(51)과 후륜측고정자(52), 회전자(53)로 이뤄진 제2가속동력구동장치로 구성되는 것을 특징으로 하는 자전거.
