Description
본 고안은 자동차 마스터 실린더에 설치된 체크밸브에 관한 것으로, 특히 오일흐름에 의한 유량의 제어시 편심되거나 혹은 뒤틀림을 방지할 수 있는 자동차 마스터 실린더의 체크밸브 구조에 관한 것이다.The present invention relates to a check valve installed in an automobile master cylinder, and more particularly, to a check valve structure of an automobile master cylinder that can prevent eccentricity or distortion in controlling the flow rate by oil flow.
일반적으로 자동차에는 마스터 실린더가 설치되어 폐달을 조작시키는 힘을 유압으로 전환시키고 있으며, 대개 클러치와, 브레이크장치에 설치되고 있다.In general, a master cylinder is installed in an automobile to convert the force for operating the lung moon into hydraulic pressure, and is usually installed in a clutch and a brake device.
일예로 상기 브레이크장치에 설치되는 마스터 실린더는 브레이크 페달을 밟는 힘을 유압으로 전환하는 장치로서, 내부에는 브레이크 오일과, 피스톤이 장착되어 있으며, 여기서 발생하는 유압은 연결파이프에 의하여 휠 실린더로 전달된다.For example, the master cylinder installed in the brake device is a device that converts the force to press the brake pedal into hydraulic pressure, the brake oil and the piston is mounted therein, the hydraulic pressure generated here is transmitted to the wheel cylinder by the connecting pipe. .
휠 실린더에 있는 피스톤은 유압에 의하여 압출되어 브레이크 슈 또는 브레이크 패드를 드럼 또는 디스크에 밀어 붙여 제동이 되도록 하는 것이고, 클러치에 설치되는 마스터 실린더는 오일을 릴리스 실린더에 압송하여 동력이 단속되도록 하는 것이다.The piston in the wheel cylinder is extruded by hydraulic pressure to brake the brake shoe or brake pad to the drum or disk for braking. The master cylinder installed in the clutch presses oil into the release cylinder so that power is interrupted.
또한, 상기 마스터 실런더에 설치된 체크 밸브는 오일이 일방향으로만 흐르게 하는 것으로 도 1은 이 체크밸브의 일예를 나타낸 것이다.In addition, the check valve installed in the master cylinder allows oil to flow in only one direction, and FIG. 1 shows an example of this check valve.
도면에서 상기 체크밸브(10)는 피스턴(20) 중앙에 형성된 중공부(21)에 삽입되어 슬라이드되는 가동부재(11)와, 이 가동부재(11)의 선단부에 형성되어 탄성부재(13)에 탄지되도록 하는 지지편(12)으로 구성되어 오일이 일방향으로만 제어되도록 하고 있다.In the drawing, the check valve 10 is inserted into the hollow part 21 formed in the center of the piston 20 and slides, and is formed at the tip of the movable member 11 to the elastic member 13. It is composed of a support piece 12 to be touched so that the oil is controlled in only one direction.
그런데, 이러한 체크 밸브(10)는 동작과정 중 오일압력과 탄성부재(13)에 의해 피스턴(20)의 중공부(21)에서 슬라이딩 되는 과정에서 가동부재(11)의 외주연에 원형으로 이루어져 회동하며 동작된다.However, the check valve 10 is rotated in a circular shape on the outer circumference of the movable member 11 in the process of sliding in the hollow portion 21 of the piston 20 by the oil pressure and the elastic member 13 during the operation process. It works.
그러나 이러한 회동동작은 중공부(21)에서 가동부재(11)가 이탈되거나 일측으로 편심되어 이동하는 문제점을 가지며, 더욱이 편심된 상태에서 이동하는 가동부재(11)는 중공부(21)를 마모시켜 동작중 오일 압력이 유출되는 문제점이 있었다.However, this rotational operation has a problem that the movable member 11 is separated or moved eccentrically to one side in the hollow portion 21, and the movable member 11 moving in the eccentric state is operated by wearing the hollow portion 21. There was a problem that the oil pressure out of the.
본 고안은 상기의 결점을 해소하기 위한 것으로, 마스터 실린더에 설치되어 오일을 일측방향으로 흐르게 하는 체크밸브에 가이드편을 형성하여 동작과정에서 편심 및 뒤틀림이 방지되도록 하는 자동차 마스터 실린더의 체크밸브구조를 제공하고자 한다.The present invention is to solve the above-mentioned shortcomings, to provide a check valve structure of the automobile master cylinder to prevent eccentricity and twisting during operation by forming a guide piece in the check valve that is installed in the master cylinder to flow the oil in one direction To provide.
이러한 본 고안은 피스턴의 중앙에 형성된 중공부에 삽입되어 오일압력에 의해 이동하며, 후방에 탄지된 탄성부재의 복원력에 의해 복귀하는 가동부재를 갖추어서된 체크밸브에 있어서, 상기 가동부재의 외측면에 가이드편을 형성하고, 이 가이드편이 삽입되어 동작중 편심을 방지하는 가이드홈이 피스턴 중앙에 형성된 중공부에 갖추어진 것으로 달성되는데, 이의 가이드편은 가동부재의 동작을 안내하여 편심 및 피스턴의 중공부 마모를 방지할 수 있는 특징을 가지는 것이다.This invention is inserted into the hollow portion formed in the center of the piston is moved by the oil pressure, the check valve is provided with a movable member that is returned by the restoring force of the elastic member supported on the rear, the outer surface of the movable member A guide groove is formed in the guide piece, and the guide piece is inserted into the hollow groove formed in the center of the piston to prevent eccentricity during operation. The guide piece thereof guides the operation of the movable member so that the hollow of the eccentric and the piston is It has a feature that can prevent side wear.

본 고안의 실시 예를 첨부 도면에 의하여 상세히 설명하면 다음과 같다.An embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 고안이 합치된 체크밸브의 조립상태를 나타낸 단면도 이고, 도 3은 본 고안의 요부 확대 단면도를 나타낸 것으로, 우선 상기 체크밸브(100)는 피스톤(200)의 중앙에 형성된 중공부(210)에 삽입되어 있는 가동부재(110)와, 이 가동부재(110)의 단부에 형성된 지지편(120) 및 이 지지편(120)을 탄지하여 복원력에 의해 가동부재(110)를 이동시키는 탄성부재(130)로 구성되어 있다.2 is a cross-sectional view showing an assembled state of the check valve according to the present invention, Figure 3 is an enlarged cross-sectional view of the main part of the present invention, first, the check valve 100 is a hollow portion formed in the center of the piston (200) Elasticity for moving the movable member 110 by restoring force by holding the movable member 110 inserted into the 210, the support piece 120 formed at the end of the movable member 110, and the support piece 120. The member 130 is comprised.
여기서 상기 가동부재(110)의 외측면에는 가이드편(101)이 돌출되어 슬라이드 동작시 이를 따라 이동되도록 하며, 이 가이드편(101)이 조립되는 가이드홈(201)은 중공부(201)의 내주연에 형성된 구성이다.Here, the guide piece 101 protrudes on the outer surface of the movable member 110 so that the guide piece 101 moves along the slide piece, and the guide groove 201 to which the guide piece 101 is assembled is formed in the hollow portion 201. It is a configuration formed on the periphery.
물론, 상기 가이드홈(201)은 가동부재(110)의 이동거리를 감안하여 형성되어 있다.Of course, the guide groove 201 is formed in consideration of the moving distance of the movable member 110.
그러면 위와 같은 구성으로 이루어진 본 고안의 작동상태를 설명하면 다음과 같다.Then explain the operating state of the subject innovation made of the above configuration as follows.
우선, 상기 피스턴(200)의 중앙에 형성된 중공부(210)에 체크밸브(100)의 가동부재(110)를 끼워고정시키며, 그 후방측은 탄성부재(130)에 의해 탄지되어 오일 압력에 의해 이동한다.First, the movable member 110 of the check valve 100 is fitted into the hollow portion 210 formed at the center of the piston 200, and the rear side thereof is supported by the elastic member 130 and moved by oil pressure. do.
이때, 상기 가동부재(110)의 외측면에 돌출된 가이드편(101)은 중공부(210)에 형성된 가이드홈(201)에 삽지되어 가동부재(110)의 이동을 안내함으로서, 동작중 편심 및 뒤틀림을 방지하고 동시에 가동부재(110)의 조립성이 향상되도록 하는 것이다.At this time, the guide piece 101 protruding on the outer surface of the movable member 110 is inserted into the guide groove 201 formed in the hollow portion 210 to guide the movement of the movable member 110, thereby causing eccentricity and To prevent distortion and at the same time to improve the assembly of the movable member (110).
이상과 같이 본 고안은 체크밸브를 구성하는 가동부재의 외측면에 가이드편을 돌출시켜 개폐에 따른 슬라이드 동작시 가동부재와 피스턴 중앙에 형성된 장공부의 마모를 방지하여 장기간의 사용을 가능하게 함은 물론, 오일압력의 누수를 방지할 수 있는 것이다.As described above, the present invention protrudes the guide piece on the outer surface of the movable member constituting the check valve to prevent the wear of the long hole formed in the center of the movable member and the piston during the slide operation according to opening and closing to enable long-term use. Of course, it is possible to prevent the leakage of oil pressure.
