본 고안은 자동차의 이동을 제어하기 위한 드럼 브레이크에 관한 것으로서, 좀더 구체적으로는 드럼 브레이크와 라이닝 수리나 교체시에 드럼 브레이크를 용이하게 분리시킬 수 있도록 한 것이다.The present invention relates to a drum brake for controlling the movement of a vehicle, and more particularly, to facilitate the separation of the drum brake and the drum brake during repair or replacement of the lining.

일반적으로 드럼 브레이크에 설치된 라이닝의 축경조절 간격은 통상 2mm 정도로서 반복 사용에 따라 라이닝이 마모되므로 라이닝과 휠의 간격을 일정하게 유지시킬 필요가 있게 된다.In general, the shaft adjustment interval of the lining installed in the drum brake is usually about 2mm, so the lining is worn with repeated use, so it is necessary to keep the distance between the lining and the wheel constant.

이에 따라 한쌍의 라이닝(1)이 고정된 슈(sShoe)(2)사이에 스트러트(4)와 어드져스터 레버(Adjuter Lever)를 다수개의 스프링으로 탄력설치하여 라이닝(1)의 마모량만큼 슈(2)를 외측으로 벌려주게 된다.Accordingly, the strut 4 and the adjuster lever are elastically installed with a plurality of springs between the shoes 2 to which the pair of linings 1 are fixed. 2) spread outwards.

이와같이 반복사용에 따른 라이닝(1)의 마모로 교체를 하거나 수리를 하고자 할 경우에는 라이닝(1)과 휠(도시는 생략함)의 간격이 극히 미세하여 분리에 많은 어려움이 따르게 되므로 이러한 경우에는 라이닝(1)의 축경을 줄여 빼내게 되는데, 이때 축경의 과다 축소를 방지하기 위한 수단의 설치가 요구된다.In this case, when replacing or repairing the lining (1) due to repeated use, the spacing between the lining (1) and the wheel (not shown) is extremely fine, which leads to many difficulties in separation. The shaft diameter of (1) is reduced and pulled out, whereby a means for preventing overshrinkage of the shaft diameter is required.

종래에는 제 4 도에 도시한 바와 같이 주차시 라이닝(1)을 휠과 접속시키기 위한 오퍼레이팅레버(13)의 끝단에 돌기(13a)를 형성함과 함께 선단은 슈(2)의 웨브(2a)에 고정된 판스프링(7)에 지지되도록 되어 있다.Conventionally, as shown in FIG. 4, the protrusion 13a is formed at the end of the operating lever 13 for connecting the lining 1 to the wheel when parking, and the tip is the web 2a of the shoe 2 as shown in FIG. It is to be supported by the leaf spring 7 fixed to it.

따라서 스트러트(4)와 어드져스트레버의 작용으로 라이닝(1)을 휠과 일정간격으로 되도록 한 상태에서 라이닝(1)을 교체하기 위해 휠에서 분리시키고자 할 경우에는 라이닝(1)이 고정된 슈(2)를 내측으로 오므러들게 하면 오퍼레이팅레버(13)가 스프링(7)과 접속되어 이동이 제어되므로 과다한 축경 조정이 방지된다.Therefore, when the lining (1) is to be separated from the wheel to replace the lining (1) in a state where the lining (1) is at a predetermined distance from the wheel by the action of the strut (4) and the adjust lever, the shoe on which the lining (1) is fixed Retracting (2) inwardly prevents excessive adjustment of the shaft diameter since the operating lever 13 is connected to the spring 7 and the movement is controlled.

그러나 이러한 종래의 드럼 브레이크는 오퍼레이팅레버(13)의 이동을 제어하기 위해 별도의 스프링(7)을 사용하게 되므로 생산성이 저하되는 문제점이 있었다.However, this conventional drum brake has a problem in that productivity is lowered because a separate spring 7 is used to control the movement of the operating lever 13.

본 고안은 종래의 이와같은 문제점을 해결하기 위한 것으로서, 별도의 스프링을 사용하지 않고도 오퍼레이팅레버의 이송량을 제어할 수 있도록 하는데 그 목적이 있다.The present invention is to solve such a problem in the prior art, the purpose is to be able to control the feed amount of the operating lever without using a separate spring.

상기 목적을 달성하기 위한 본 고안 형태에 따르면, 주차시 사용되는 오퍼레이팅레버의 선단에 돌출부를 형성하여 돌출부가 슈의 웨브에 걸려 이송이 제어될 수 있도록 된 드럼 브레이크가 제공된다.According to the present invention for achieving the above object, there is provided a drum brake in which a protrusion is formed at the tip of the operating lever used for parking so that the protrusion is caught on the web of the shoe so that the feeding can be controlled.

이하, 본 고안을 일실시예로 도시한 첨부된 도면 제 1 도 내지 제 3 도에 도시한 바와 같이 라이닝(1)이 고정되는 슈(2)의 웨브(2a)에 오퍼레이팅레버(3)가 회동가능하게 결합되어 있고 상기 오퍼레이팅레버(3)의 선단에는 돌출부(3a)가 엠보싱되어 슈(2)의 웨브(2a)에 걸리도록 되어 있다.Hereinafter, the operating lever 3 is rotated to the web 2a of the shoe 2 to which the lining 1 is fixed, as shown in the accompanying drawings 1 to 3 showing an embodiment of the present invention. It is possible to engage, and the protrusion 3a is embossed at the tip of the operating lever 3 so as to be caught by the web 2a of the shoe 2.

한편 오퍼레이팅레버(3)의 끝단에는 스트러트(4)와 어드져스트레버(5)가 상호 스프링으로 탄력설치되어 있어 반복 사용에 따라 라이닝(1)과 휠의 간격을 유지시키기 위해 어드져스트레버(5)를 회동시켜주면 슈(2)가 외측으로 벌어져 라이닝(1)과 휠의 간격이 보정된다.On the other hand, at the end of the operating lever 3, the strut 4 and the adjuster lever 5 are elastically installed with each other, so that the adjuster lever 5 can maintain the gap between the lining 1 and the wheel according to repeated use. Rotating the shoe 2 opens to the outside, and the distance between the lining 1 and the wheel is corrected.

이러한 상태에서 라이닝(1)을 교체시켜주기 위해 휠에서 분리시키고자 할 경우에는 플러그(6)를 분리시킨 후 드라이버 등으로 어드져스트레버(5)를 눌러주면 슈(2)가 내측으로 이동되어 축경이 작아지는데, 이때 오퍼레이팅레버(3)에 형성된 돌출부(3a)가 슈(2)의 웨브(2a)에 걸리게 되므로 축경이 과다하게 축소되는 것을 방지할 수 있게 되는 것이다.In this case, if you want to remove the lining (1) from the wheel in order to replace the plug (6) and then press the adjuster lever 5 with a screwdriver or the like, the shoe (2) is moved to the inside diameter In this case, the protrusion 3a formed on the operating lever 3 is caught by the web 2a of the shoe 2, thereby preventing the shaft diameter from being excessively reduced.

이상에서와 오퍼레이팅레버(3)에 돌출부(3a)를 형성하여 돌출부(3a)가 웨브(2a)에 걸리므로서 축경이 과다하게 줄어드는 것을 방지할 수 있게 되므로 부품의 간소화로 인한 생산성을 향상시킬 수 있게 된다.Since the projection 3a is formed on the operating lever 3 as described above, the projection 3a can be caught by the web 2a, thereby preventing the shaft diameter from being excessively reduced, so that the productivity due to the simplification of parts can be improved. do.
