Abstract

본 발명은 운전자의 의도에 따라 레버를 선택조정한 후, 페달을 역방향으로 밟음에 따라서, 페달의 역구동력이 베벨기어의 변환 구동에 의하여 전진구동이 이루어질 수 있도록 하는 동시에, 또한 레버의 선택조정에 의하여 기존의 자전거와 마찬가지로 페달의 역구동시에 공회전이 가능하도록 하여, 운전자의 피로를 덜고 힘의 손실을 방지하며, 다리근육의 균형있는 발달을 일상생활에서 단련할 수 있는 자전거의 전진구동 주행장치에 관한 것으로, 자전거의 페달축(10)에 스프로켓축받이(31)가 일방향클러치수단(80)으로 결합되어 페달의 구름력이 전달될 수 있도록 되어 있는 동시에, 뒷바퀴와 체인으로 연결되는 구동스프로켓(30)과; 상기 페달축(10)에 고정되어 상기 구동스프로켓(30)과 연결구동되는 제1베벨기어(40)와; 상기 제1베벨기어(40)와 이맞물림구동되며 베벨축받이(51)에 지지되어 유동가능한 제2베벨기어와(50); 변환레버(20)에 의하여 슬라이드 이동되어 상기 제2베벨기어(50)의 베벨축받이(51)를 이맞물림으로 유지 고정시킬 수 있는 변환커플링체(60)로 이루어져, 페달축(10)의 역구동을 베벨기어로 변환시키어 구동스프로켓(30)이 정방향으로 구동되도록 한 것이다.According to the present invention, when the lever is selected and adjusted according to the driver's intention, the pedal's reverse driving force enables the forward driving to be performed by the bevel gear's conversion drive as the pedal is reversed. As a conventional bicycle, the bicycle can be idled at the time of reverse driving to reduce the driver's fatigue, prevent the loss of power, and to improve the balance of leg muscles in daily life. The sprocket shaft support 31 is coupled to the pedal shaft 10 of the bicycle by the one-way clutch means 80 so that the rolling force of the pedal can be transmitted, and the driving sprocket 30 is connected to the rear wheel and the chain. ; A first bevel gear 40 fixed to the pedal shaft 10 and connected to the driving sprocket 30; A second bevel gear 50 engaged with the first bevel gear 40 and movable by being supported by the bevel bearing 51; It is composed of a conversion coupling body (60) which is slide-shifted by the conversion lever (20) to hold the bevel bearing (51) of the second bevel gear (50) in engagement. Is converted to a bevel gear so that the drive sprocket 30 is driven in the forward direction.
