본 고안은 자동차용 드럼 브레이크의 브레이크 슈우를 연결하는 링크장치에 관한 것으로, 특히 브레이크 슈우에 가이드홀을 형성하고 링크의 가이드핀을 가이드홀에 삽입하여 브레이크 작동시 링크가 유동되도록 하는 자동차용 드럼 브레이크의 작동시 링크가 유동되도록 하는 자동차용 드럼 브레이크의 링크장치에 관한 것이다.The present invention relates to a link device for connecting a brake shoe of an automobile drum brake, and in particular, to form a guide hole in the brake shoe and insert the guide pin of the link into the guide hole for the automobile drum brake to allow the link to flow during brake operation It relates to a linkage device for a vehicle drum brake that allows the link to flow during operation.
종래의 자동차용 드럼 브레이크에 사용되던 링크장치는 휠실린더가 결합된 브레이크 슈우의 대향측에만 링크를 고정시켜 양측의 브레이크 슈우를 연결한 후 2개의 인장스프링으로 브레이크 슈우의 상하측을 탄지하였으나, 이는 브레이크의 작동시 일측의 브레이크 슈우의 라이닝이 드럼에 완전히 밀착되지 못하여 브레이크 효율이 저하되는 결점이 있었다.The link device used in the conventional automobile drum brake fixed the link only to the opposite side of the brake shoe to which the wheel cylinders were coupled to connect the brake shoes on both sides, and then supported the upper and lower sides of the brake shoe with two tension springs. The lining of the brake shoe on one side did not come into close contact with the drum during the operation of the brake, which resulted in a decrease in the brake efficiency.
따라서, 본 고안의 목적은 양측 브레이크 슈우를 연결하는 링크를 상하측에 구비하면서 링크를 유동되도록 설치함으로서 브레이크 작동시 양측 라이닝을 드럼에 완전히 밀착시키고 브레이크의 효율을 증대시킬 수 있도록 한 자동차용 드럼 브레이크의 링크장치를 제공함에 있다.Therefore, an object of the present invention is to provide a link for connecting both brake shoes on the upper and lower sides so that the link flows so that both sides of the lining in close contact with the drum during brake operation can increase the efficiency of the brake brake To provide a link device of the.
이하, 본 고안을 첨부도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail by the accompanying drawings.
드럼(1)내에 라이닝(3)이 부착된 2개의 반원형 브레이크 슈우(2)가 삽입되고 그 상단에는 휠실린더(4)가 설치되며, 2개의 인장스프링(7)으로 브레이크 슈우(2)를 탄지하는 자동차용 드럼 브레이크에 있어서, 양측 브레이크 슈우(2)의 상하측에 가이드홀(5)(6)을 형성하고 2 개의 링크(10)(11) 양단에 구비된 가이드핀(12)(13)을 가이드홀(5)(6)에 삽입하여 브레이크 슈우(2)의 상하측에 링크(10)(11)가 구성되도록 하여서 된 것이다.Two semicircular brake shoes 2 with a lining 3 attached to the drum 1 are inserted, and wheel cylinders 4 are installed at the upper end thereof, and the brake shoes 2 are supported by two tension springs 7. In a drum brake for automobiles, guide pins (5) and (6) are formed on the upper and lower sides of both brake shoes (2) and guide pins (12) (13) provided at both ends of the two links (10) (11). Is inserted into the guide holes 5 and 6 so that the links 10 and 11 are formed on the upper and lower sides of the brake shoe 2.
이와같이 구성된 본 고안은 제 1 도와 같이 브레이크 슈우(2)에 부착된 라이닝(3)이 드럼(1)에서 이탈되어 있는 상태에서 브레이크 페달을 밟아 휠실린더(4)가 동작되도록 하면 제 2 도와 같이 양측 브레이크 슈우(2)의 라이닝(3)이 드럼(1)에 모두 밀착되는 것이다.The present invention configured as described above has both sides as shown in the second diagram when the wheel cylinder 4 is operated by stepping on the brake pedal while the lining 3 attached to the brake shoe 2 is separated from the drum 1 as the first diagram. The lining 3 of the brake shoe 2 is in close contact with the drum 1.
즉, 휠실린더(4)가 동작되면 브레이크 슈우(2)가 외측으로 밀리면서 인장스프링(7)을 인장시키고 브레이크 슈우(2) 상하측의 링크(10)(11)는 그 양단의 가이드핀(12)(13)이 브레이크 슈우(2)에 형성된 가이드홀(5)(6)을 따라 이동하게 되므로 외측으로 밀리는 브레이크 슈우(2)의 이동이 원활하게 이루어지면서 양측 브레이크 슈우(2)의 라이닝(3)이 드럼(1)에 모두 밀착되는 것이다.That is, when the wheel cylinder 4 is operated, the brake shoe 2 is pushed outward to tension the tension spring 7, and the links 10 and 11 at the upper and lower sides of the brake shoe 2 are guide pins at both ends thereof. 12) 13 moves along the guide holes 5 and 6 formed in the brake shoes 2, so that the brake shoes 2 pushed outward smoothly and the linings of the brake shoes 2 on both sides ( 3) is in close contact with the drum (1).
한편, 브레이크 페달에서 발을 떼면 휠실린더(4)가 제 1 도와 같이 복귀되면서 인장스프링(7)의 텐션력이 브레이크 슈우(2)의 상하측을 당기게 되므로 브레이크 슈우(2)와 링크(10)(11)도 원상복귀 되는 것이다.On the other hand, when the foot is released from the brake pedal, the wheel cylinder 4 returns with the first degree, and the tension force of the tension spring 7 pulls up and down the brake shoe 2, so that the brake shoe 2 and the link 10 (11) is also restored.
상기에서와 같이 본 고안은 브레이크 드럼내의 브레이크 슈우 상하측에 가이드홀을 형성하고 그 상하측의 가이드홀에 각각의 링크를 유동 가능하게 결합함으로서 브레이크의 작동시 양측 브레이크 슈우의 라이닝이 드럼에 균일하게 밀착되고 브레이크 효율을 증대시킬 수 있는 효과가 제공되는 것이다.As described above, the present invention forms a guide hole on the upper and lower sides of the brake shoe in the brake drum and couples each link to the guide hole on the upper and lower sides so that the lining of both brake shoes is uniformly applied to the drum when the brake is operated. The effect is to be in close contact and to increase the brake efficiency.
