Description

페달아암과 마스터실린더 푸시로드의 연결장치Connection between pedal arm and master cylinder push rod

본 발명은 자동차의 페달에 관한 것이며, 특히는 페달아암과 마스터실린더 푸시로드의 연결장치에 관한 것이다.The present invention relates to a pedal of an automobile, and more particularly, to a connecting device of a pedal arm and a master cylinder push rod.

자동차의 브레이크와 클러치는 페달에 의해 작동되며, 페달은 브레이크와 클러치를 작동하기 위한 마스터실린더의 푸시로드와 연결되어 있다.The brakes and clutches of the vehicle are operated by pedals, which are connected to the push rods of the master cylinder for operating the brakes and clutches.

예컨데, 유압식 브레이크 시스템은 브레이크페달을 작동시키면 페달아암에 요크로 연결된 푸시로드에 의해 마스터 실린더내의 피스톤이 전진하여 실린더내의 브레이크 오일을 압축하므로써, 전, 후륜측의 브레이크라인을 통해 브레이크 오일을 압축하에 되며, 브레이크라인의 종단과 연통된 캘리퍼(전륜측)나 브레이크슈(후륜측)의 실린더로 고압의 브레이크 오일을 공급하여 라이닝이나 패드를 브레이크드럼(내부확장식, 후륜)이나 디스크(캘리퍼식, 전륜측)에 압착하여 마찰에 의해 제동이 이루어지게 된다. 또한, 브레이크페달을 해방시키면 압축되었던 브레이크 오일이 마스터 실린더로 복귀하며 브레이크가 해제되게 된다.For example, the hydraulic brake system compresses the brake oil through the front and rear brake lines by compressing the brake oil in the cylinder by moving the piston in the master cylinder by the push rod connected to the pedal arm when the brake pedal is activated. The high pressure brake oil is supplied to the cylinder of the caliper (front wheel side) or brake shoe (rear wheel side) in communication with the end of the brake line, and the lining or pad can be replaced with the brake drum (internal extension, rear wheel) or disc (caliper type, The front wheel side) is pressed to brake by friction. Also, releasing the brake pedal causes the brake oil to be returned to the master cylinder to release the brake.

한편, 수동 변속 자동차에 있어서, 유압식 클러치는 클러치페달을 밟으면 클러치페달에 연결된 마스터실린더의 푸시로드가 마스터실린더 내의 피스톤이 클러치 오일을 압축하여 릴리즈포크를 작동시켜 클러치를 분리하여 동력전달을 차단하게 된다.On the other hand, in the manual transmission vehicle, when the hydraulic clutch depresses the clutch pedal, the push rod of the master cylinder connected to the clutch pedal causes the piston in the master cylinder to compress the clutch oil to operate the release fork to disconnect the clutch to block power transmission. .

도 1에 종래의 일반적인 페달의 구성이 도시되어 있다. 도시된 바와 같이, 브레이크페달이나 클러치페달은 페달부재(2)의 바아나 파이프로 구성되는 회전축(3)에 페달아암(1)이 회전이 자유롭게 지지되며 브레이크나 클러치의 마스터실린더(도시하지 않음)와 연결된 푸시로드(4)의 종단에 형성된 ㄷ 자형의 요크(5)와 클레비스핀(6)을 이용하여 체결되어 있다.1 shows a configuration of a conventional general pedal.

The c-shaped yoke 5 and clevis pin 6 formed at the end of the connected push rod 4 are fastened.

이에따라, 페달을 밟게 되면 페달아암(1)이 회전하며 푸시로드(4)를 밀어 마스터실린더내의 오일을 압축하여 브레이크나 클러치를 작동시키게 된다.Accordingly, when the pedal is pressed, the pedal arm 1 rotates and pushes the push rod 4 to compress oil in the master cylinder to operate the brake or the clutch.

도 2에 종래의 페달아암(1)과 요크(5)의 결합방식의 일례가 도시되어 있다.2 shows an example of a conventional coupling method of the pedal arm 1 and the yoke 5.

도시된 바와같이, 페달아암(1)은 클레비스핀(6)에 부싱(9)을 통해 견고히 고정되며, 클레비스핀(6)과 요크(5)는 스냅핀(8)에 의해 결합되게 된다. 이를 위해, 클레비스핀(6)의 종단에는 탄성부시(7)를 개재하여 핀홀에 스플릿타입의 스냅핀(snappin, 8)이 설치되어 요크(5)와 클레비스핀(6)과의 고정이 이루어지게 된다.As shown, the pedal arm 1 is firmly fixed to the clevis pin 6 through the bushing 9, and the clevis pin 6 and the yoke 5 are coupled by the snap pin 8. . To this end, a split type snap pin (8) is installed at the end of the clevis pin (6) via an elastic bush (7) to fix the yoke (5) and the clevis pin (6). Will be done.

이와 같은 종래의 페달아암(1)과 마스터실린더의 요크(5)의 결합방식은 클레비스핀(6)과 스냅핀(8)의 체결에 따라 단지 구성부품의 이탈을 방지하는 것에 그치게 되며, 제조공차 등에 따라 핀(6)과 요크(5)의 관통공 사이의 유격에 의해 페달(1)에 의한 무효스트로크가 발생하게 되며, 소음의 원인이 된다는 점이 단점으로 지적되고 있다.The conventional coupling method of the pedal arm (1) and the yoke (5) of the master cylinder is merely to prevent the departure of the components according to the engagement of the clevis pin (6) and snap pin (8), manufacturing It is pointed out that the invalid stroke caused by the pedal 1 is generated due to the clearance between the through hole of the pin 6 and the yoke 5 according to the tolerance and the like, which causes noise.

이러한 종래의 클레비스핀(6)과 페달아암(1) 및 요크(5)의 결합구조상의 문제점을 감안하여, 본 발명은 무효스트로크가 발생하지 않으며 소음의 우려가 없는 페달아암과 마스터실린더의 푸시로드의 연결장치를 제공하는 것을 목적으로 한다.In view of the problems of the conventional structure of the combination of the clevis pin 6, the pedal arm 1 and the yoke 5, the present invention is the push of the pedal arm and the master cylinder that does not generate an invalid stroke and there is no fear of noise It is an object to provide a connecting device of a rod.
