본 고안의 브레이크슈와 주차 브레이크 레버 사이에 흘드다운 크립을 개재하여 브레이크와 드럼 분리시 슈경을 축소토록한 드럼 브레이크의 슈경 축소장치에 관한 것으로, 홀드다운 클립을 코일스프링에 탄지토록 함으로서 제작 및 조립이 간편하고 사용중 고장을 일으킬 염려가 전혀 없도록 하는데 그 목적이 있다.Shoe diameter reduction device of drum brake which reduces shoe diameter when brake and drum are separated through a brake down between the brake shoe and parking brake lever of the present invention, and is manufactured and assembled by holding the hold down clip on the coil spring. Its purpose is to make it simple and not cause any trouble during use.
종래에는 슈경 축소장치가 없었기 때문에 브레이크 사용시 슈 라이닝이 마모됨에 따라 슈경을 뜨게하여 주는 조정장치에 의하여 브레이크슈가 벌어지면서 브레이크 드럼에 끼이는 상태가 되므로서 브레이크슈의 라이닝을 교체하고자 브레이크와 드럼을 분리하는데 많은 어려움이 따랐으며 이를 보완하기 위해 판스프링을 일체로 형성시킨 홀드다운 클립에 있어서도 그 제작이 어렵고 사용중 탄성한계를 못이겨 파손됨으로서 홀드다운 클립으로서 제역활을 하지 못하는 것이 현실정이다.Since there is no shoe diameter reduction device in the past, the brake shoe is opened by the adjusting device that opens the shoe diameter as the shoe lining wears when the brake is used, and the brake shoe is caught and the state is caught in the brake drum. In order to compensate for this, it is difficult to manufacture a hold down clip that is integrally formed with a leaf spring, and it cannot be used as a hold down clip because it is damaged due to an elastic limit during use.
본 고안은 이와같은 종래의 제결함을 감안하여 홀드다운 클립을 코일스프링에 탄지한 것으로, 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention is to hold the clip to the coil spring in consideration of the conventional defects, such as described in detail based on the accompanying drawings as follows.
브레이크슈(1)와 주차 브레이크 레버 (2)사이에 홀드다운 클립(3)을 개재하여 브레이크와 드럼 분리시 슈경을 축소토록한 드럼 브레이크의 슈경 축소장치에 있어서, 상기 브레이크슈(1)와 주차 브레이크 레버(2) 사이에 요홈(3a)이 형성된 걸림편(3')을 가지는 홀드다운 클립(3)을 설치하고 코일스프링(4)으로 탄지토록 한 것으로, 미설명 부호3b는 스프링(4)의 미끄럼을 방지하는 돌기, 5는 라이닝, 6은 자동조정장치, 7은 브레이크의 백플레이트이며, 8은 브레이크슈(1)와 홀드다운클립(3)을 결합하는 앵커핀이며, 9는 스프링 고정용 캡이고, 10은 휘일실린더이다.In the shoe diameter reduction device of a drum brake, the brake shoe (1) and the parking brake lever (2) are interposed between the brake shoe (1) and the parking brake lever (2) via a hold down clip (3). A hold down clip 3 having a locking piece 3 'having a groove 3a formed between the brake levers 2 is provided and held with a coil spring 4, and reference numeral 3b denotes a spring 4 Anti-slip projection, 5 is lining, 6 is automatic adjustment device, 7 is back plate of brake, 8 is anchor pin to connect brake shoe (1) and hold down clip (3), and 9 is spring fixed Is a dragon cap, and 10 is a wheel cylinder.
이와같이 구성된 본 고안의 작용효과를 설명하면, 브레이크슈(1)와 주차 브레이크 레버(2)사이에 홀드다운 클립(3)의 걸림편(3')을 개재한 상태에서 브레이크를 사용하던 중 브레이크슈(1)의 외연에 부착된 라이닝(5)이 마모됨에 따라 브레이크슈(1)와 드럼과의 간격이 커지기 때문에 이를 보완하기 위하여 자동조정장치(6) (스타휘일조정기등에 의거 외경을 넓혀주는 장치)가 라이닝(5)이 마모된 량만큼 브레이크슈(1)를 벌려서 드럼과의 간격이 항상 일정하게 유지하게 되는데, 브레이크를 너무 오래 사용하여 라이닝(5)을 갈아 끼우고자 할때는 라이닝이 마모된 칩등이 브레이크슈(1)와 드럼사이에 끼어서, 별도의 드럼과 브레이크의 분리가 잘되지 않기 때문에 브레이크슈(1)와 주차 브레이크 레버(2)사이에 홀드다운플립(3)의 걸림편(3')을 드라이버등의 공구를 이용하여 브레이크슈(1) 상부로 밀어올리면 제3도에서와 같이 코일스프링(4)에 탄지된 홀드다운클립(3)이 상승하면서 걸림편(3')에 밀착되어 지지되던 주차브레이크레버(2)가 우측으로 이동됨과 동시에 상기 주차 브레이코 레버(3)에 일측이 지렛대 작용으로 지지되었던 브레이크슈(1)가 좌측으로 이동되어 슈경이 축소되게 한 것이다.When explaining the operation and effect of the present invention configured as described above, the brake shoe while using the brake in the state of interposing the engaging piece (3 ') of the hold down clip (3) between the brake shoe (1) and the parking brake lever (2) As the lining (5) attached to the outer edge of (1) is worn out, the distance between the brake shoe (1) and the drum increases, so as to compensate for this, the automatic adjusting device (6) (a device for increasing the outer diameter based on a star wheel adjuster, etc.) The gap between the drum is always kept constant by spreading the brake shoe (1) by the amount that the lining (5) is worn, but when the lining (5) is replaced by using the brake too long, the lining is worn out. A chip or the like is caught between the brake shoe 1 and the drum, and the separate drum and the brake are not easily separated, so that the engaging piece 3 of the hold down flip 3 between the brake shoe 1 and the parking brake lever 2 Tools such as screwdriver When the upper side of the brake shoe 1 is pushed up, the parking brake lever 2 which is held in close contact with the latching piece 3 'while the hold down clip 3 supported by the coil spring 4 ascends as shown in FIG. ) Is moved to the right and at the same time the brake shoe 1, which was supported on one side by the lever of the parking brake nose lever 3 is moved to the left to reduce the shoe diameter.
상기한 바와같이 본 고안은 홀드다운 클립(3)의 걸림편(3')에 요홈(3a)를 형성하였기 때문에 드라이버등 공구가 미끄러질 염려가 전혀 없으며, 홀드다운 클립(3)과 코일스프링(4)이 별개로 형성되기 때문에 부품의 제조 및 조립이 용이할 뿐만 아니라, 사용중 고장을 일으킬 염려가 전혀 없는 등 그 실사용 가치를 일층 고양시킨 신규유용의 고안이다.As described above, the present invention is provided with a recess 3a in the engaging piece 3 'of the hold down clip 3, so that there is no fear that the tool such as a driver slips, and the hold down clip 3 and the coil spring 4 ) Is not only easy to manufacture and assemble parts, but also a new utility designed to further enhance its practical value, such as no fear of breakdown during use.
