본고안은 평행구동라이닝의 드럼브레이크에 관한 것으로서, 더욱 상세히는 자동차 드럼브레이크에서 라이닝이 장착된 슈우의 작동방식을 개선한 것에 관한 것이다.The present invention relates to a drum brake of a parallel driving lining, and more particularly, to an improved method of operating a shoe fitted with a lining in an automobile drum brake.
일반적인 자동차의 드럼브레이크는 원형상의 드럼내에 라이닝을 그 외벽면에 구비한 슈우를 일지점을 힌지고정하여 유압실린더의 신축작동으로 드럼의 내벽면과 슈우의 패드상 라이닝을 상호 접속시키거나 이탈시켜 제동을 수행하고 있다.In general, the drum brake of a car is fixed to a shoe having a lining in a circular drum on its outer wall and fixed at one point, and the hydraulic cylinder is stretched to connect or brake the inner wall of the drum and the pad-shaped lining of the shoe. Is doing.
상기와 같은 종래의 구성에서는 일지점을 중심으로 슈우가 회동하는 구성이기 때문에, 라이닝이 원호상의 접촉을 행하게 되어 면압이 국부적으로 상이하여 드럼 내벽면과의 접촉시에 접촉개시점에서의 마모는 큰 반면 접촉종료점의 라이닝의 마모가 적어 부분적인 리아닝의 마모에도 불구하고 전체 라이닝을 교환하여야 하는 문제가 있고, 또한 힌지축을 중심으로 하는 레버구성이기 때문에 상호 부재가 엉켜버리거나 걸리는 레버록킹현상이 발생하여 고장의 원인이 되기도 한다.In the conventional configuration as described above, since the shoe is rotated around one point, the lining makes arc-shaped contact, and the surface pressure is locally different, so that the wear at the contact start point is large when contacting the drum inner wall surface. On the other hand, there is a problem that the lining of the contact point is less wearable, so that the entire lining needs to be replaced in spite of the wear of the partial lining, and because of the lever structure centered on the hinge axis, the interlocking members are entangled or caught. It can also cause malfunction.
상기와 같은 문제점을 감안하여 본고안의 평행구동라이닝의 드럼브레이크는 라이닝의 접촉을 드럼내벽면에 대하여 평행하게 수행할 수 있도록 하여 균일한 라이닝의 마모와 고장의 극소화를 도모한다.In view of the above problems, the drum brake of the parallel drive lining of the present invention enables the contact of the lining to be performed in parallel with the inner wall of the drum, thereby minimizing wear and failure of the uniform lining.
이하의 부수된 도면과 함께 본고안의 평행구동라이닝의 드럼브레이크를 더욱 상세하게 설명한다.The drum brake of the parallel drive lining of the present invention will be described in more detail together with the accompanying drawings below.
제1도는 본고안의 평행구동라이닝의 드럼브레이크의 일실시예를 도시하는 평면도, 제2도는 본고안의 평행구동라이닝의 드럼브레이크에 사용되기에 적합한 휠실린더의 일실시예의 단면도이다.FIG. 1 is a plan view showing one embodiment of a drum brake of parallel drive lining in this article, and FIG. 2 is a cross-sectional view of one embodiment of a wheel cylinder suitable for use in a drum brake of parallel drive lining in this paper.
통상적인 원통형상의 드럼(10) 내벽에는 종래의 슈우와 거의 유사한 원호상의 슈우(11,12)가 한쌍 백플레이트(20)상에 가이드되면서 그 외벽면에 라이닝(16,17)을 가지면서 장착된다.On the inner wall of a conventional cylindrical drum 10, arc-shaped shoes 11, 12, which are almost similar to conventional shoes, are mounted on the pair of back plates 20 with linings 16, 17 on their outer wall surfaces. .
상기 슈우(11,12)는 서로 평행하게 대향하도록 배치한다.The shoes 11 and 12 are arranged to face each other in parallel.
슈우(11,12)의 내측향으로는 돌출하여 연장한 신축가이드바아(13,13',14,14')가 한쌍 슈우(11,12)에 강고하게 각각 설치된다.The extension guide bars 13, 13 ', 14, 14' which protrude and extend inwardly of the shoes 11 and 12 are firmly attached to the pair of shoes 11 and 12, respectively.
상기의 신축가이드바아(13,13',14,14')는 드럼 내하방에 설치되는 통상적인 백플레이트(20)상에 개략“U”형상으로 돌출고정되는 가이드안내홈(21)을 각각 상하에 일개소씩 구비하며 이러한 가이드구성은 랙및 랙가이드형식등의 다양한 구성이 가능할 것이다.The extension guide bars 13, 13 ', 14 and 14' respectively have guide guide grooves 21 which protrude and fix in a roughly "U" shape on a conventional back plate 20 installed below and below the drum. The guide structure will be provided in one place at a variety of configurations, such as rack and rack guide type.
신축가이드바아(13,13',14,14')는 가이드안내홈(21)내방에 안착되어 좌우로 미끄럼자유롭게 끼워지고 슈우(11,12)의 양 내단사이에는 한쌍의 휠실린더(30,31)가 긴밀하게 설치되고 상기의 슈우(11,12)사이에는 복귀스프링(33,34)이 인장력으로 작용하면서 구비된다.The extension guide bars 13, 13 ', 14, 14' are seated inside the guide guide groove 21 and slide freely from side to side, and a pair of wheel cylinders 30 and 31 between both inner ends of the shoe 11 and 12. ) Is closely installed and return springs 33 and 34 are provided between the shoes 11 and 12 while acting as a tensile force.
제2도는 본고안의 평행구동라이닝의 드럼브레이크에 사용하기에 적합한 휠실린더를 단면도로서 도시하는 것으로서 통상적인 휠실린더를 사용하여도 무방하나 제2도이하의 휠실린더(30,31)가 바람직하다.2 is a cross-sectional view of a wheel cylinder suitable for use in a drum brake of parallel drive lining in this paper. A conventional wheel cylinder may be used, but wheel cylinders 30 and 31 below the second preferred embodiment are preferred.
휠실린더(30,31)는 양단의 작동피스톤(40,41)의 직경(d,D)이 상이하게 구성되고 작동유체가 작용하는 실린더(42)도 역시 이에 상응하도록 내경을 가짐으로서 양 슈우(11,12)에 인가되는 작동력이 직경(d,D)의 차이만큼 상이하게 인가된다.The wheel cylinders 30 and 31 are configured with different diameters d and D of the working pistons 40 and 41 at both ends, and the cylinder 42 to which the working fluid acts also has an inner diameter such that both wheels ( 11, 12 is applied differently by the difference of the diameter (d, D).
이러한 작동인가력의 차이는 회전방향에서 먼쪽의 슈우측(A,B)에 인가되도록 한다.This difference in operating force is applied to the shoe sides A and B far from the rotational direction.
상기의 구성의 본고안의 평행구동라이닝의 드럼브레이크에서는 드럼(10) 내벽면에 대하여 슈우(11,12)가 평행하게 접속하였다가 이탈함으로서 제동력이 라이닝(16,17)전체에 걸쳐서 균일하게 인가되고 그에따라 라이닝(16,17)의 마모도 균일하게 발생함으로서 라이닝의 수명을 연장하고 평행작동하는 기구를 구비함으로서 기구적인 방해 현상도 제거할 수있다.In the drum brake of the parallel driving lining of the above structure, the braking force is uniformly applied throughout the linings 16 and 17 by the shoes 11 and 12 being connected in parallel to the inner wall of the drum 10 and then detached. As a result, the wear of the linings 16 and 17 is evenly generated, thereby extending the life of the linings and providing mechanisms for parallel operation, thereby eliminating mechanical disturbances.
이상과 같은 본고안의 평행구동라이닝의 드럼브레이크는 라이닝의 균일한 마모를 도모하고 기구적인 안정성을 제고함으로서 작동신뢰성을 증대하는 유용한 고안인 것이다.The drum brake of the parallel drive lining as described above is a useful design to increase the operational reliability by promoting uniform wear of the lining and improving mechanical stability.
