본 발명은 자전거용 무단변속장치에 관한 것으로, 사용자의 조작없이 주행환경에 따른 구동력과 하중의 변화에 따라 자동적으로 무단변속이 가능하고, 주행 및 변속시 발생하는 동력을 발전기를 통해 충전하며, 중심축의 역회전을 방지하고, 필요시 부하제공부를 통해 변속을 수동으로도 조절할 수 있도록, 사용자가 중심축을 구동시켜 회전시키고, 중심축의 회전력을 제1캐리어, 제1유성기어, 제1링기어, 제1선기어, 출력축 순으로 전달받아 회전시 저항에 따라 자동 변속하면서 출력축으로 전달하는 변속부와, 상기 변속부와 연동되게 설치하여 변속부에 선택적으로 부하를 제공하는 부하제공부로 이루어져, 주행환경에 맞춰서 기어 조절이 용이한 효과가 있다.

    The present invention relates to a continuously variable transmission for a bicycle. The continuously variable transmission for a bicycle can automatically shift gears continuously in response to changes in driving force and load according to the bicycle-riding environment without user intervention, recharges, by means of a generator, with power generated during riding and shifting, prevents reverse rotation of the central shaft, and also allows transmission to be manually controlled by means of a load-providing unit when necessary. To that end, the continuously variable transmission for a bicycle comprises: a transmission unit which receives rotational power from the central shaft, which is driven and rotated by a user, and automatically shifts gears in response to resistance when rotating, the rotational power being delivered in the order of a first carrier, a first planetary gear, a first ring gear, a first sun gear, and an output shaft; and a load-providing unit which is installed to engage with the transmission unit and selectively provides a load to the transmission unit. Therefore, the continuously variable transmission for a bicycle facilitates gear changes based on the bicycle-riding environment.
