The present invention relates to a bicycle rear wheel acceleration device for improving driving speed. A structure, in which the acceleration device including a central axle shaft (11), a sun gear (12), a planetary gear (23), a ring gear (25), a planetary gear carrier (24) and a spring device is able to be simply installed in a housing (51) of a driving wheel, is applied to bicycles of a gearshift chain style (21) and a general chain operation style. Therefore, since the rotational force of a driving wheel is doubled in accordance with the elastic intensity of a spring and the gear ratio of a planetary gear device, the rotation speed of the driving wheel can become faster than the rotation speed of a general bicycle, so a bicycle rider can accelerate speed for riding with less power when having to climb up a slope or having to speed up. Moreover, since various combination methods for each acceleration device are changed, bicycles having various types of accelerations effects can be manufactured.

    본 발명은 주행속도향상을 위한 자전거 뒤바퀴 가속장치에 관한 것으로 중앙액슬축(11), 태양기어(12), 유성기어(23), 링기어(25), 유성기어캐리어(24),스프링장치를 포함하는 가속장치를 구동바퀴의 하우징(51)안에 간단하게 장착이 가능한 구조로 변속체인기어방식(21),일반체인구동방식인 자전거에 적용 설치함으로서, 구동바퀴의 회전력을 유성기어장치의 기어비율,스프링의 탄성강도에 따라 배가시켜 구동바퀴의 회전속도를 통상 자전거의 회전속도보다 높여 자전거 이용자가 속도를 내거나 경사지를 오르기위해 많은 힘을 필요로 하던 것을 적은 힘으로도 주행속도를 증속시킬 수 있는 효과가 있으며, 각각의 가속장치의 다양한 결합방법의 변경으로 여러 가지 형태의 가속효과를 가진 자전거를 만들 수 있는 효과가 있다.
