본 고안은 자동차의 엔진마운팅(Engine Mounting)에 사용되는 부시(Bush)구조에 관한 것으로써, 더욱 상세히 설명하면 러버 부시내에 유체를 봉입시킨 자동차의 엔진마운팅용 부시에 관한 것이다.The present invention relates to a bush structure used for engine mounting of an automobile, and more particularly, to an engine mounting bush of an automobile in which fluid is enclosed in a rubber bush.
엔진마운팅은 엔진마운트 또는 엔진서포트라고도 부르며 엔진을 지지하며 차체에 고정된 부품을 의미한다.Engine mounting, also called engine mount or engine support, is a part that supports the engine and is fixed to the body.
이러한 엔진마운팅에는 엔진과 엔진마운팅간을 연결하는 부시가 결합되는데 이는 엔진의 진동을 차체에 전달하지 못하도록 방진 기능을 가지며, 고무로 만들어진 커버마운팅이나 고무내에 액체(Oil)를 봉입하여 진동의 감쇠력을 크게 한 액체봉입엔진마운팅 등이 있다.The engine mounting is combined with a bush that connects the engine and the engine mounting, which has a dustproof function to prevent the vibration of the engine from being transmitted to the vehicle body, and the damping force of the vibration is prevented by enclosing the oil in the cover mounting or rubber made of rubber. Liquid encapsulated engine mounting.
예시도면 제1도 및 제2도는 종래의 엔진마운팅(1)과 연결브라켓(2)을 도시한 것으로, 엔진마운팅(1)은 아우터 파이프(3)의 내측에 고무(4)가 충진되어 있고, 고무(4)를 관통하는 인너 튜브(5:Inner Tube) 및 공간부(6)가 형성되어 있다.1 and 2 show a conventional engine mounting 1 and a connection bracket 2, the engine mounting 1 having rubber 4 filled inside the outer pipe 3, An inner tube 5 and a space 6 penetrating the rubber 4 are formed.
또한 아우터 파이프(3)의 외금구 브라켓(7)과 결합보울트(8)가 형성되어 마운팅 멤버(9)에 결함할 수 있도록 되어 있고, 엔진(10) 및 트랜스미션(11)에 결합된 연결 브라켓(2)에는 결합축(12)이 고무(4)의 인너 튜브(5)를 관통하여 결합되도록 되어 있다. 따라서 엔진의 하중이 연결브라켓(2)을 통하여 고무(4)에 전달되고 이러한 충격 및 소음등이 고무(4)에 의하여 완화된다.In addition, the outer bracket (7) and the coupling bolt (8) of the outer pipe (3) is formed to be able to be defective in the mounting member (9), the coupling bracket coupled to the engine (10) and the transmission (11) 2) the coupling shaft 12 is coupled to penetrate the inner tube 5 of the rubber (4). Therefore, the load of the engine is transmitted to the rubber 4 through the connecting bracket 2, and such shocks and noises are alleviated by the rubber 4.
특히, 충격흡수는 공간부(6)에 의하여 고무(4)가 충분히 변형될 수 있게 되어 효과적으로 이루어질 수 있도록 되어 있다.In particular, the shock absorption is to be effectively made to the rubber 4 can be sufficiently deformed by the space (6).
상기 고무(4)에는 예시도면 제2도에서 알 수 있는 바와 같이 인너 튜브(5)의 상·하측에 각각 공간부(6)가 형성되어 있고, 그 사이에 인너 튜브(5)가 형성되어 있어서 엔진의 하중이 상·하로 미치는 것을 완화시키도록 되어 있다.As shown in FIG. 2 of the drawing, the rubber 4 has a space 6 formed on the upper and lower sides of the inner tube 5, and an inner tube 5 is formed therebetween. It is designed to mitigate the load on the engine up and down.
엔진마운팅용 러버부시(Rubber Bush)를 이용하여 엔진을 지지하게 되면, 하중이 적은 경우에는 효과적이지만 하중이 크게 작용하는 곳에는 효과적인 하중지지 및 롤(Roll)의 제어가 어렵고 내구성이 저하되는 결점이 있는 것이다.Supporting the engine by using a rubber bush for engine mounting is effective when the load is small, but where the load is large, effective load support and control of the roll are difficult and durability is degraded. It is.
또한 예시도면 제3도와 같은 종래의 오일 봉입형 엔진마운팅(13)의 구조를 보면 고무(14) 내에 오일(15)이 충진되고 하부에는 공간부(16)가 형성되어 오일이 그 사이의 상광하협형의 오리피스(Orifice)를 통과함으로써 충격을 완충시키도록 되어 있다.In addition, in the structure of the conventional oil-sealed engine mounting 13 as shown in FIG. 3, the oil 15 is filled in the rubber 14, and a space portion 16 is formed in the lower portion thereof, so that the oil is in the upper and lower valleys therebetween. The shock is cushioned by passing through the orifice of the mold.
그러나 상기와 같은 오일봉입형 엔진마운팅(1)은 구조가 복잡하고 제작이 어려우며 효과적인 지지 및 제어가 곤란한 결점이 있는 것이다.However, the oil-sealed engine mounting 1 as described above has a drawback in that the structure is complicated, difficult to manufacture, and effective support and control are difficult.
본 고안은 상기한 바와 같은 종래의 러버부시 또는 오일봉입형 부시가 갖는 결점을 해결하기 위하여 고무 내에 유체를 상하로 봉입하여 고무의 탄성과 유체의 압축력 및 유체내의 공기압등을 적절히 이용함으로서 엔진의 진동을 효과적으로 감쇠 또는 흡수하는 동시에, 그 구조가 간단하고 지지 및 제어력이 뛰어난 엔진마운팅용 부시를 제공함에 목적이 있다.The present invention encloses the fluid up and down in the rubber to solve the drawbacks of the conventional rubber bush or oil-sealed bush as described above, by appropriately using the elasticity of the rubber and the compressive force of the fluid and the air pressure in the fluid, etc. It is an object of the present invention to provide an engine mounting bush which effectively attenuates or absorbs the carbon fiber, and at the same time has a simple structure and excellent support and control.
상기와 같은 목적을 실현하기 위한 본 고안은 아우터 파이프내에 고무를 결합함에 있어서 중앙의 고무를 중심으로 상·하부에 유체를 내입하고 유체 내에는 공기가 갇혀 있도록 한 것이다.The present invention for realizing the above object is to incorporate the fluid into the upper and lower centers of the rubber in the center in the coupling of the rubber in the outer pipe and to trap the air in the fluid.
본 고안을 첨부된 예시도면과 함께 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings.
본 고안은 엔진마운팅(1)의 아우터 파이프(3)내에 고무(4)를 내입한 것에 있어서, 인너 튜브(5)를 중심으로 고무(4)의 상·하부에 유체(17)를 봉입시키고 유체(17)내에는 공기(18)를 주입한 구조로 되어 있다.In the present invention, the rubber 4 is embedded in the outer pipe 3 of the engine mounting 1, and the fluid 17 is sealed in the upper and lower portions of the rubber 4 around the inner tube 5, and the fluid is In 17, air 18 is injected.
예시도면 제4도는 본 고안에 따른 엔진마운팅(1)의 사시도로서 아우터 파이프(3) 내측에 고무(4)가 충진되어 있다.4 is a perspective view of an engine mounting 1 according to the present invention, and the rubber 4 is filled inside the outer pipe 3.
예시도면 제5도는 본 고안에 따른 엔진마운팅(1)의 단면도로서 아우터 파이프(3)의 내부에는 고무(4)가 3개층으로 나뉘어서 그 사이에 유체(17)가 주입되는 공간이 형성되며, 공간내에는 유체(17)와 공기(18)가 함께 주입된다.5 is a cross-sectional view of the engine mounting 1 according to the present invention. In the interior of the outer pipe 3, rubber 4 is divided into three layers to form a space in which the fluid 17 is injected therebetween. In the fluid 17 and the air 18 are injected together.
유체(17)와 공기(18)는 함께 봉입되어 외부로 빠져 나갈 수 없도록 되어 있고 외부에서 압력을 받게 되면 유체(17)내의 공기(18)가 압축되면서 충격을 흡수하게 되어 있다.The fluid 17 and the air 18 are enclosed together so that they cannot escape to the outside, and when the pressure is received from the outside, the air 18 in the fluid 17 is compressed to absorb shocks.
본 고안은 엔진마운팅(1)의 아우터 파이프(3)내에 고무(4)를 충진하되 고무내에 상, 하 대칭형의 공간부를 형성하여 그 내측에 유체(17)와 공기(18)를 봉입함으로써 고무의 탄성과 공기의 압축력을 완충 효과로 이용할 수 있는 것이다.The present invention fills the rubber (4) in the outer pipe (3) of the engine mounting (1), but forms a space of up and down symmetry in the rubber to seal the fluid (17) and air (18) inside the rubber Elasticity and air compressive force can be used as a cushioning effect.
