제2도는 본 고안의 작동상태를 예시한 정면도.Figure 2 is a front view illustrating the operating state of the present invention.
제3도는 제2도 A-A선 횡단면도.3 is a cross-sectional view taken along the line A-A of FIG.
본 고안은 자전거의 후차륜 허브에 착설되는 브레이크의 구조에 관한 것으로서 허브에 고정된 회전드럼의 내외면을 라이닝판이 협지하도록 하여 제동력의 향상과 소음의 제거를 기하도록 한 것이다.The present invention relates to a structure of a brake installed on the rear wheel hub of a bicycle, so that the lining plate pinches the inner and outer surfaces of the rotating drum fixed to the hub to improve braking force and remove noise.
종래의 자전거 브레이크는 거의가 밴드 브레이크로서 회전 드럼의 외면을 라이닝판이 압지하게 되어 있어서 라이닝판과 회전드럼이 마찰될 때 심한 소음이 발생하게 되고 강한 제동력을 나타낼 수 없었다.Most of the conventional bicycle brakes are band brakes, and the lining plate is pressed against the outer surface of the rotating drum, so that when the lining plate and the rotating drum are rubbed, high noise is generated and the braking force cannot be exhibited.
본 고안은 상기와 같은 종래의 결점을 해결하기 위하여 안출된 것으로 첨부 도면에 의거하여 설명하면 다음과 같다.The present invention has been devised to solve the above-mentioned drawbacks as described below based on the accompanying drawings.
후차륜 허브에 축설되는 브레이크 케이스(a)와 회전드럼(b)으로 되는 자전거 브레이크에 있어서, 돌출부(1')가 돌출된 외부 작동판(1)의 상단부(1")에 코일스프링(s)을 탄설하고 이에 내부작동판(2)의 상단을 지축(3)으로 유착하며 하단은 케이스(a)의 벽면에 지축(3')으로 축설하여 외부작동판(1)의 돌출부(1')내면과 내부 작동판(2)의 외면에는 각각 호형 라이닝판(4)(4')을 간격(H)이 생기도록 부착하고 외부작동판(1)의 돌출부(1')에 선단(6)이 접촉되게한 압지판(5)은 장공(8)에 축설된 보조링크(7)에 유착시켜서된 것이다.In a bicycle brake comprising a brake case (a) and a rotating drum (b) arranged on the rear wheel hub, the coil spring (s) is provided at the upper end (1 ") of the external operation plate (1) on which the protrusion (1 ') protrudes. And the upper end of the inner operating plate (2) is adhered to the support shaft (3), and the lower end is constructed on the wall surface of the case (a) with the support shaft (3 ') to form the inner surface of the protrusion (1') of the external operation plate (1). Arc-shaped lining plates 4 and 4 'are attached to the outer surfaces of the inner working plate 2 so as to form a gap H, and the tip 6 contacts the protrusions 1' of the outer working plate 1, respectively. The tack plate 5 is made by adhering to the auxiliary link 7 built in the long hole (8).
도면중 미설명부호 9는 인장와이어 10은 복귀스프링, 11은 각 라이링판의 간격 조절용 보울트를 보인 것이다. 이와 같이 된 본 고안의 작용효과를 설명하면 다음과 같다.In the figure, reference numeral 9 is a tension wire 10 is a return spring, 11 is shown a bolt for adjusting the spacing of each of the lining plate. Referring to the effect of the present invention made as follows.
외부 작동판(1)의 돌출부(1')에 부착된 라이닝판(4)와 내부작동판(2)의 외면에 부착된 라이닝판(4')사이의 간격(H)으로 공지의 회전드럼(b)주면이 들어가게 되어있어서 평상시는 차륜이 원활하게 회전될수 있다.Known rotating drums with a spacing H between the lining plate 4 attached to the protrusion 1 'of the outer operating plate 1 and the lining plate 4' attached to the outer surface of the inner operating plate 2; b) The main surface is entered so that the wheel can rotate smoothly.
이와 같은 주행상태에서 자전거를 급정거시키기 위하여 인장와이어(9)를 당기게 되면 이에 연결된 압지판(5)이 보조링크(7)를 중심으로 하여 하향 회전되면서 그 선단(6)이 외부작동판(1)의 돌출부(1')를 압압하여 아래로 밀게되고 따라서 외부작동간(1)은 상부 지축(3)에 함께 연결되어 있는 내부작동판(2)을 당기게 되어 스프링(s)이 신장되면서 내부작동판(2)은 하부지축(3')을 중심으로 우회전하게 된다.When the tension wire 9 is pulled to suddenly stop the bicycle in such a driving state, the pressure-sensitive plate 5 connected thereto is rotated downwardly about the auxiliary link 7, and the front end 6 of the bicycle is connected to the external operation plate 1. The protrusion 1 'of the pressing unit is pushed down and thus the external operation section 1 pulls the inner operating plate 2 connected together to the upper support shaft 3 so that the spring s is extended and the inner operating plate is extended. (2) is to turn right about the lower axis (3 ').
따라서 이때 외부작동판(1)의 라이닝판(4)과 내부작동판(2)의 라이닝판(4')은 각각 그들 사이에 끼워져 있는 회전드럼(b)의 측벽을 내외면에서 협지하게되어 강한 제동작용을 하게되며 동시에 라이닝판(4)(4')이 내외면에서 협지하게 됨으로 소음 발생이 거의 없다.Therefore, at this time, the lining plate 4 of the outer operating plate 1 and the lining plate 4 'of the inner operating plate 2 respectively sandwich the sidewalls of the rotating drum b sandwiched therebetween at the inner and outer surfaces. At the same time, the lining plate (4) (4 ') is sandwiched from the inner and outer surfaces and there is little noise.
그리고 제동을 풀어줄 때는 당기던 와이어(9)만 놓아주면 수축되있던 복귀 스프링(10)이 탄발되면서 압지판(5)을 내측으로 밀어주게 됨으로 압지판(5)의 선단(6)이 외부작동판(1)의 돌출부(1')에서 떨어지게되고 따라서 스프링(s)의 복귀작용에 의하여 내외작동판(1)(2)의 원위치로 복귀되면서 라이닝판(4)(4')이 회전드럼(b)으로부터 떨어지면서 자전거는 다시 정상으로 운행하게 된다.When releasing the braking, when only the wire 9 is released, the return spring 10, which has been contracted, is pushed inward and the pusher plate 5 is pushed inward so that the tip 6 of the pusher plate 5 is the external operation plate. The lining plate (4) (4 ') is rotated from the protrusion (1') of the (1) and thus returned to the original position of the inner and outer operating plates (1) and (2) by the return action of the spring (s). Off the bike, the bike runs back to normal.
이상과 같이 본 고안은 자전거를 강력하면서도 비교적 소음이 없이 급정거 시킬 수가 있게되는 것이다.As described above, the present invention is capable of stopping the bicycle suddenly without compromising powerful yet relatively noise.
