Description

자동차의 유체봉입식 엔진마운트Fluid-mounted engine mounts for cars

본 고안은 자동차의 엔진을 탑재함에 있어 이를 지지하도록 사용되는 유체봉입식 엔진마운트에 관한 것으로, 보다 더 상세하게는 엔진의 동작중 이로부터 발생된 대변위의 진동을 효과적으로 감쇠시켜 엔진의 진동을 제어할 수 있도록 된 자동차의 유체봉입식 엔진마운트에 관한 것이다.The present invention relates to a fluid-enclosed engine mount that is used to support an engine of a vehicle, and more particularly, effectively controls the vibration of the engine by attenuating large displacement vibration generated therefrom during operation of the engine. It relates to a fluid-enclosed engine mount of a vehicle that can be.

일반적으로 자동차의 엔진은 내부의 피스톤과 컨넥팅로드의 상하운동에 의한 중심위치의 주기적인 변화와, 실린더 축방향으로 생기는 왕복운동부분에서 발생되는 관성력, 커넥텅로드가 크랭크축의 좌우로 흔들림에 따라 발생되는 관성력 및, 크랭크축에 가해지는 회전력의 주기적인 변화에 따른 것등에 의해 동작중 진동과 소음이 유발된다.In general, the engine of an automobile has a periodic change in the center position caused by the vertical movement of the piston and the connecting rod, the inertial force generated in the reciprocating portion occurring in the axial direction of the cylinder, and the connecting tongue rod swings to the left and right of the crankshaft. Vibration and noise are generated during operation due to the inertia force generated and the periodic change in rotational force applied to the crankshaft.

이에 따라 엔진은, 동작중 차체로 전달되는 진동을 최소화하거나, 엔진의 움직임을 제어하여 내구성을 향상시키기 위해 엔진의 하부에 다수개(통상 3내지 4곳)의 지점으로 적절한 스프링강성을 지닌 고무로 제작된 엔진마운트를 장착시켜 엔진룸내에 탑재되어 있고,Accordingly, the engine is made of rubber with appropriate spring stiffness at a number of points (usually three to four places) at the bottom of the engine to minimize vibrations transmitted to the vehicle body during operation or to control the movement of the engine to improve durability. It is installed in the engine room by mounting the manufactured engine mount,

그런데, 상기와 같은 목적을 달성하기 위해 사용되는 엔진마운트 중에서 부쉬타입의 엔진마운트는, 도 1 에 도시된 바와 같이, 내측파이프(11)의 외주면에 내부에 중공의 공간부(12)를 다수개의 구비한 고무재의 완충부재(13)가 고착되고, 이 완충부재(13)의 외주면에 외측파이프(14)가 고착되어 끼워지며, 이 외측파이프(14)에는 차체의 프레임에 결합되는 브라켓트(15)가 장착되어 있다.However, among the engine mounts used to achieve the above object, the bush type engine mount has a plurality of hollow spaces 12 formed therein on the outer circumferential surface of the inner pipe 11, as shown in FIG. 1. A cushioning member 13 of a rubber material is fixed, and an outer pipe 14 is fixed to and fitted to an outer circumferential surface of the buffer member 13, and the outer pipe 14 has a bracket 15 coupled to a frame of a vehicle body. Is equipped.

그리하여 상기와 같은 구조로 된 부쉬타입의 엔진마운트는, 상기 브라켓트(15)가 차체프레임에 결합되어 고정장착되고, 상기 내측파이프(11)로는 볼트와 같은 체결수단이 끼워져 엔진에 고정된 브라켓트(도시안됨)와 동시에 체결되어 설치된다.Thus, the bush type engine mount having the structure as described above, the bracket 15 is fixed to the vehicle body frame is fixedly mounted, the inner pipe 11 is fastened to the engine by a fastening means such as bolts (not shown) No)) and is installed at the same time.

그러나 상기와 같은 부쉬타입의 엔진마운트는 엔진의 동작중 차체로 전달되는 대변위의 진동을 절연시킬 때 이를 전적으로 내측파이프(11)와 외측파이프(14) 사이에 개재된 완충부재(13)에만 의존하는데, 가해지는 진동이 완충부재(13)의 스프링강성보다 크게 되면 이를 효과적으로 절연시키지 못하는, 즉 저주파 대변위의 진동에서 엔진쇽크를 억제시켜 엔진의 진동을 제어하여 내구성을 향상시키기 위한 높은 강성 및 높은 감쇠력을 발휘하는 마운트이 특성을 충분히 발휘할 수 없는 단점이 있었다.However, the bush type engine mount as described above relies solely on the shock absorbing member 13 interposed between the inner pipe 11 and the outer pipe 14 when insulating the vibration of the large displacement transmitted to the vehicle body during operation of the engine. However, if the applied vibration is greater than the spring stiffness of the shock absorbing member 13, it does not effectively insulate it, that is, high stiffness and high for improving durability by controlling the engine vibration by suppressing the engine shank at low frequency large displacement vibration. There was a disadvantage that the mount exhibiting damping force could not fully exhibit its characteristics.

이에 본 고안은 상기와 같은 단점을 해소하기 위해 안출된 것으로, 엔진의 동작중 이로 부터 발생되는 저주파 대변위시의 진동에서 이를 큰 감쇠력으로 절연시키는 대변위진동제진수단을 구비함으로써 엔지으로부터 발생되는 대변위의 진동에 효과적으로 대처할 수 있도록 된 자동차의 유체봉입식 엔진마운트를 제공함에 그 목적이 있다.The present invention has been devised to solve the above disadvantages, and has a large displacement vibration damping means to insulate it with a large damping force in the vibration of the low frequency large displacement generated therefrom during operation of the engine, thereby causing a large displacement generated from the engine. The purpose of the present invention is to provide a fluid-mounted engine mount for a vehicle that can effectively cope with vibrations.

이하 본 고안의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2 는 본 고안에 따른 유체봉입식 엔진마운트의 단면도이고, 도 3 은 도 2 의 측단면도이다.2 is a cross-sectional view of the fluid-mounted engine mount according to the present invention, Figure 3 is a side cross-sectional view of FIG.

본 고안은 도면에 도시된 바와 같이, 내측파이프(1)와 이의 외주면에 중간파이프(2)를 고무재의 제 1 완충부재(3)를 매개로 가류접착시키고, 이 중간파이프(2)의 외주면에 외측파이프(4)를 역시 고무재의 제 2 완충부재(5)를 매개로 가류접착시키며, 상기 내측파이프(1)와 중간파이프(2)가 형성하는 상/하부액실(6)에 유체를 봉입시키면서 내측파이프(1)측에 오리피스연결구멍(7)을 갖는 고무스톱퍼(8)를 부착시키는 한편, 상기 중간파이프(2)에는 파이프형 오리피스(9)를 압입시키면서 이에 상/하액실(6)로 연통되는 관통구(10)를 형성시킨다.According to the present invention, as shown in the drawing, the inner pipe 1 and the outer circumferential surface thereof are subjected to vulcanization adhesion of the intermediate pipe 2 through the first buffer member 3 of rubber material, and to the outer circumferential surface of the intermediate pipe 2. The outer pipe 4 is subjected to vulcanization adhesion through the second buffer member 5 of rubber material, and the fluid is enclosed in the upper / lower liquid chamber 6 formed by the inner pipe 1 and the intermediate pipe 2. A rubber stopper 8 having an orifice connecting hole 7 is attached to the inner pipe 1 side, while the pipe type orifice 9 is pressed into the intermediate pipe 2 to the upper / lower liquid chamber 6. The through hole 10 communicates with each other.

따라서 상기와 같이 내측파이프(1)가 이에 제 1 완충부재(3)를 매개로 액실(6)을 형성하는 중간파이프(2)와 내부에 오리피스연결구멍(7)을 갖는 고무스톱퍼(8)를 구비함과 더불어 이 중간파이프(2)는 제 2 완충부재(5)를 매개로 외측파이프(4)를 고착시키면서 오리피스(9)와 액실(6)로 연통되는 관통구(10)를 갖춤에 따라, 대변위의 진동이 입력될 경우에 상기 액실(6)내의 유체가 받는 압축력에 의해 수축되는 고무스톱퍼(8)의 오리피스연결구멍(7)을 통해 큰 감쇠력을 얻어 대변위의 진동을 효과적으로 제진하므로 엔진의 쇽크를 줄일 수 있게 된다.Accordingly, as described above, the inner pipe 1 has a rubber stopper 8 having an intermediate pipe 2 forming the liquid chamber 6 through the first buffer member 3 and an orifice connecting hole 7 therein. In addition, the intermediate pipe 2 has a through hole 10 which communicates with the orifice 9 and the liquid chamber 6 while fixing the outer pipe 4 through the second buffer member 5. When a large displacement vibration is input, a large damping force is obtained through the orifice connecting hole 7 of the rubber stopper 8, which is contracted by the compressive force of the fluid in the liquid chamber 6, thereby effectively damping the large displacement vibration. The shank of the engine can be reduced.
