Description

휴대와 보관이 편리한 무체인 전륜구동 자전거{Chainless Front Wheel driving bicycle with portability and keeping}[0001] The present invention relates to a bicycle, a bicycle,

본 발명은 휴대와 보관이 편리한 무체인 전륜구동 자전거에 관한 것으로, 더욱 상세하게는 자전거 페달의 발구름에 의해 발생하는 회전력을 페달과 연결된 동력발생부와 플렉시블 케이블에 의해 전륜구동부에 전달하여 전륜을 구동시키고, 상기 전륜의 구동에 의해 후륜이 구동되는 체인이 없는 전륜구동방식 자전거에 관한 것이다.
The present invention relates to an all-wheel drive bicycle which is easy to carry and store. More particularly, the present invention relates to an all-wheel drive bicycle, Driven bicycle without a chain in which the rear wheels are driven by driving the front wheels.

일반적으로 자전거는 페달의 발구름에 의해 전륜을 회전시키는 전륜구동방식과, 후륜을 회전시키는 후륜구동방식 및 전륜과 후륜을 동시에 회전시키는 양륜구동방식이 있다.
Generally, a bicycle has an all-wheel drive system in which front wheels are rotated by a pedal crest, a rear-wheel drive system in which a rear wheel is rotated, and a two-wheel drive system in which front and rear wheels are simultaneously rotated.

도 1은 종래기술인 하이휠 자전거의 사시도이고, 도 2는 종래기술인 리컴번트 자전거의 사시도로, 종래기술의 전륜구동방식 자전거는 체인구동장치 없이 페달을 전륜회전축에 연결하여 페달의 발구름에 의해 전륜을 회전시키는 하이휠 자전거와, 전륜에 체인구동장치를 장착하고 페달을 전륜회전축에 연결하여 전륜을 회전시키는 리컴번트 자전거가 있다.
FIG. 1 is a perspective view of a conventional high-wheel bicycle, and FIG. 2 is a perspective view of a conventional recumbent bicycle. In the conventional all-wheel drive bicycle, a pedal is connected to a front wheel rotation shaft without a chain drive device, There is a recumbent bicycle that rotates the front wheel by attaching the chain driving device to the front wheel and connecting the pedal to the front wheel rotation axis.

그러나 전륜에 페달이 구비된 하이휠 자전거는 후륜을 작게 할 수 있어 휴대성은 높으나 체인 등의 구동장치가 없어서 속도를 높이는데 한계가 있으며, 전륜에 체인구동장치가 장착된 리컴번트 자전거는 사용자의 다리 사이에 전륜이 설치된 것이므로 구동과 방향전환을 동시에 하는 경우 자전거 운전이 불안정할 수 있다.
However, the high-wheel bicycle having a pedal on the front wheel has a small rear wheel, which is high in portability. However, since there is no driving device such as a chain, there is a limit to increase the speed, and a recumbent bicycle equipped with a chain driving device on the front wheel, The bicycle operation may be unstable when driving and turning directions at the same time.

자전거를 레저와 스포츠를 위한 용도로 사용하는 인구가 증가하면서 휴대와 보관이 편리한 자전거의 필요성이 증가하고 있으며, 이를 위해 자전거의 크기를 작게 하려는 시도가 있으나, 자전거는 바퀴의 크기에 따라 속도가 달라지는 특성이 있으므로 종래의 후륜구동방식 자전거는 후륜의 크기를 줄이면 속도가 느려지므로 자전거의 크기를 줄이는데 한계가 있다.
As the population increasingly uses bicycles for leisure and sports purposes, there is an increasing need for bicycles that are portable and easy to store. For this purpose, attempts have been made to reduce the size of bicycles. However, The conventional rear wheel drive bicycle has a limitation in reducing the size of the bicycle because the speed of the rear wheel is reduced.

도 3은 종래기술인 양륜구동 자전거의 사시도로, 종래기술의 양륜구동 자전거(300)는 전륜과 후륜을 동시에 회전시켜 자전거의 추동력을 증대하기 위한 것으로, 페달의 발구름에 의해 발생된 회전력을 페달에 인접한 동력발생부에 전달하고, 상기 동력전달부(310)는 체인(325)에 의해 후륜구동부(330)에 회전력을 전달하여 후륜(360)을 회전시키며, 동시에 상기 동력전달부(310)는 플렉시블 케이블(340)에 의해 전륜구동부(350)에 회전력을 전달하여 전륜(370)을 회전시킨다.
FIG. 3 is a perspective view of a conventional two-wheel drive bicycle. The conventional two-wheel drive bicycle 300 is for rotating the front wheel and the rear wheel simultaneously to increase the braking force of the bicycle. And the power transmission unit 310 transmits rotation force to the rear wheel drive unit 330 by the chain 325 to rotate the rear wheel 360. The power transmission unit 310 is a flexible And transmits the rotational force to the front wheel drive unit 350 by the cable 340 to rotate the front wheel 370.

그러나 전륜과 후륜을 동시에 회전시키는 양륜구동 자전거는 후륜구동이 주가 되고 전륜구동은 이를 보조하여 구동력을 높이는 방식으로, 동력발생부와 후륜구동부가 체인에 의해 연결되며, 전륜과 후륜의 크기가 동일해야 하므로 자전거의 크기를 작게 할 수 없어서 자전거의 휴대와 보관이 용이하지 못하다.
However, the two-wheel drive bicycle which rotates the front wheel and the rear wheel at the same time is mainly driven by the rear wheel drive, and the all-wheel drive is assisted by this to increase the driving power. The power generating portion and the rear wheel drive portion are connected by a chain. The size of the bicycle can not be reduced, so that it is not easy to carry and store the bicycle.
