본 고안은 자동차의 제둥장치에 있어 드럼형 브레이크 제동장치에 관한 것이다.The present invention relates to a drum type brake braking device in a braking device of an automobile.
특히, 휘일실린더의 유압으로 브레이크 드럼에 압착되는 브레이크 슈우와 상기 브레이크 슈우의 마찰력을 받아 제동력을 발생하는 브레이크 드럼에 마찰계수 및 마찰력을 식혀주는 장치에 관한 것이다.In particular, the present invention relates to a brake shoe pressed against a brake drum by hydraulic pressure of a wheel cylinder and an apparatus for cooling a friction coefficient and a friction force to a brake drum generating a braking force by receiving a friction force of the brake shoe.
일반적으로 자동차의 제동장치는 유압식으로 드럼형 브레이크와 디스크 브레이크로 나눌수 있다.In general, the braking device of a vehicle is hydraulically divided into a drum brake and a disk brake.
드럼형 브레이크는 휘일실린더의 유압으로 브레이크 드럼에 압착되는 T단면을 가지는 브레이크 슈우와 회전할때 브레이크 슈우의 마찰력을 받아 제동력을 발생하는 브레이크 드럼으로 이루어져 있으며 상기 브레이크 슈우에는 라이닝을 붙어있어 드럼과의 사이에서 마찰력에 의하여 제동작용을 하는 것으로 이때 마찰열에 의해 온도가 상승하게 된다.The drum type brake is composed of a brake shoe having a T section that is pressed against the brake drum by hydraulic pressure of the wheel cylinder, and a brake drum which generates braking force by receiving friction of the brake shoe when rotating. The brake shoe has a lining attached to the drum. The braking action is performed by the frictional force between and the temperature is increased by the frictional heat.
즉, 여름철 온도가 높을때 긴 내리막길 등에서 풋브레이크를 많이 사용하면, 브레이크의 드럼과 라이닝이 과열되어 휘일실린더 등의 브레이크 오일속에 기포가 생기게 되고, 이에 따라 브레이크 페달을 밟아도 유압이 전달되지 않아 브레이크가 잘작동되지 않은 베이퍼록(Vapperlock)현상이 발생함과, 고속주행 중 긴 내리막길등에서 짧은 시간안에 풋브레이크를 지나치게 사용해서 브레이크 슈우와 드럼이 과열하면 브레이크 라이닝이 높은 온도때문에 변질되고, 따라서 마찰계수가 극히 작아져서 미끄러지며, 브레이크가 듣지 않는 페이드(Fade)현상이 발생하여 제동력이 부족함에 따라 크나큰 사고의 위험성이 제거되었다.In other words, if the foot brake is used a lot on long downhill when the temperature is high in summer, the drum and lining of the brake will overheat, causing air bubbles in the brake oil such as the wheel cylinder, and thus the hydraulic pressure will not be delivered even when the brake pedal is pressed. If the brake shoe and drum overheat due to excessive use of foot brakes in short periods of time, such as long downhills during high-speed driving, overheating of the brake shoes and drums, the brake linings are deteriorated due to high temperatures. The coefficient was extremely small and slipped, and the brakes did not fade, causing the braking force to be eliminated.
본 고안은 이와같은 문제점을 해결하기 위하여 안출한 것으로 브레이크 슈우에 부착된 라이닝의 표면에 유출홈을 구비하고, 드럼의 외·내측으로 공기 유입공과 유입홈을 구성하여 브레이크 라이닝에서 발생하는 마찰열을 유입되는 공기로 식혀주어 높은 제동력을 얻고자 하는데 그 목적이 있다.The present invention has been devised to solve such a problem and has an outflow groove on the surface of the lining attached to the brake shoe, and constitutes an air inlet hole and an inflow groove to the outside and the inside of the drum to introduce friction heat generated from the brake lining. The purpose is to obtain high braking force by cooling with air.
이하에서 첨부된 도면에 의거하여 본 고안의 기술적 구성을 상세히 살펴본다.Hereinafter, the technical configuration of the present invention will be described in detail with reference to the accompanying drawings.
라이닝(3)과 브레이크 드럼(1)과의 사이에서 발생하는 마찰열을 식혀주기 위해 T단면의 브레이크 슈우(2)에 압착된 라이닝(3)의 표면에 유출홈(10)을 형성하고, 브레이크 드럼(1)의 외·내측면에 상기 유출홈(10)의 방향과 엇갈리도록 공기 유입홈(11)과 유입홈(12)을 각각 구성한다.In order to cool the frictional heat generated between the lining 3 and the brake drum 1, an outflow groove 10 is formed in the surface of the lining 3 squeezed by the brake shoe 2 of the T section, and the brake drum The air inlet grooves 11 and the inlet grooves 12 are formed on the outer and inner sides of (1) so as to cross the direction of the outlet groove 10.
이와같이 구성된 본 고안의 작용효과를 살펴보면, 제3도에 도시된 바와같이 브레이크 폐달(9)를 밟으면 마스터 실린더(8)내의 피스톤(7)은 오일을 휘일실린더(4)내로 압송한다.Looking at the effect of the present invention configured as described above, as shown in FIG. 3, when the brake pedal (9) is pressed down, the piston (7) in the master cylinder (8) pumps oil into the wheel cylinder (4).
휘일실린더(4)는 유압으로 인하여 피스톤(7)을 좌우로 밀어내어 이로 인해 브레이크 슈우(2)는 브레이크 드럼(1)의 내측면에 압착되어 브레이크 작용을 하고 브레이크 페달(9)에서 발을떼면 마스터 실린더(8)내의 유압은 낮아지게 되어 브레이크 슈우(2)는 슈우 리턴 스프링(5)에 의해서 원위치로 돌아오므로 휘일실린더(4)내의 오일은 마스터 실린더(8)내로 돌아와 브레이크 작용은 풀린다.The wheel cylinder 4 pushes the piston 7 from side to side due to the hydraulic pressure, which causes the brake shoe 2 to be squeezed to the inner surface of the brake drum 1 to brake and to release the brake pedal 9. Since the hydraulic pressure in the master cylinder 8 is lowered and the brake shoe 2 is returned to its original position by the shoe return spring 5, the oil in the wheel cylinder 4 returns to the master cylinder 8 to release the brake action.
상기와 같이 브레이크 페달(9)을 밟았을때 휘일실린더(4)의 유압에 의해 라이닝(3)이 압착된 브레이크 슈우(2)에 맞닿으면서 마찰열이 발생하게 되는데 이때 브레이크드럼(1)동체의 외주면에 형성된 공기 유입공(11)에서 내측면의 유입홈(12)으로 공기가 유입되어 브레이크 슈우(2)에 압착된 라이닝(3)의 표면에 형성된 유출홈(10)이 서로 X자로 교차하면서 회전하게 됨으로써 라이닝(3)의 표면이 브레이크드럼(1)동체의 내측면에 형성된 유입홈(12)에 맞닿아 라이닝(3)표면에서 발생되는 마찰열을 공기에 의해 최단시간에 식혀주어 높은 제동효과을 얻을 수 있다.As described above, when the brake pedal 9 is pressed, friction heat is generated while the lining 3 is pressed against the brake shoe 2 compressed by the hydraulic pressure of the wheel cylinder 4. Air flows from the air inlet hole 11 formed on the outer circumference 11 to the inlet groove 12 of the inner side, and the outlet grooves 10 formed on the surface of the lining 3 squeezed by the brake shoe 2 cross each other with an X-shape. By rotating, the surface of the lining 3 abuts the inflow groove 12 formed in the inner surface of the brake drum 1, thereby cooling the frictional heat generated from the surface of the lining 3 with air in the shortest time, thereby providing a high braking effect. You can get it.
이와같이 본 고안은 브레이크의 드럼과 라이닝에서 발생하는 마찰열과 마찰계수를 적게하여 베이퍼록(Vapper Lock)현상과 페이트(Fade)현상을 제어함에 따라 높은 제동력을 얻을 수 있는 잇점이 있다.As such, the present invention has the advantage that high braking force can be obtained by controlling the vapor lock phenomenon and the fade phenomenon by reducing frictional heat and coefficient of friction generated in the drum and lining of the brake.
