Abstract

본 발명은 자전거용 무단 변속장치에 관한 것으로, 변속 조작을 용이하게 하고, 각 변속단간의 변속비를 최소화시켜 승차감을 향상시키며, 동력 전달부재를 축으로 사용하여 체인과 스프로켓으로 인한 부상이나 옷에 손상을 줄일 수 있는 자전거용 무단 변속장치에 관한 것이다.The present invention relates to a continuously variable transmission for a bicycle, to facilitate the shift operation, to minimize the speed ratio between each shift stage to improve the ride comfort, damage to injury or clothes caused by chains and sprockets using the power transmission member as an axis The present invention relates to a continuously variable transmission for a bicycle.

구동 방법으로는 구동력을 발생하는 페달축에 마찰면을 갖는 원판기어를 설치하고 후륜허브에 베벨기어를 설치하여, 상기 원판기어와 베벨기어를 동력 전달부재로 연결하여 구동력을 전달하되, 동력 전달부재의 양끝단부에 베벨기어와 이동기어를 설치 형성하여 후륜 허브의 베벨기어와 맞물리는 베벨기어는 고정 설치하고 원판 기어와 맞물리는 이동기어는 축방향으로는 이동 가능하고 회전방향으로는 고정되게 하여 증속 감속을 할 수 있게 한 것을 특징으로 하는 자전거용 무단 변속장치.As a driving method, a disc gear having a friction surface is installed on a pedal shaft generating a driving force, a bevel gear is installed on a rear wheel hub, and the disc gear and the bevel gear are connected to a power transmission member to transmit a driving force. Bevel gears and moving gears are installed at both ends of the bevel gear so that the bevel gears meshing with the bevel gears of the rear hub are fixedly installed, and the shift gears meshing with the disc gears are movable in the axial direction and fixed in the rotational direction. Continuously variable speed gear for bicycles, characterized in that the deceleration can be made.
