Description
본 고안은 자동차의 엔진마운트에 관한 것으로, 보다 더 상세하게는 진동에 의한 축방향의 과대변위를 억제시키도록 엔진마운트의 완충부재내에 스톱퍼를 내장시켜 축방향의 과대변위에 따른 타부품과의 간섭을 억제시키도록 된 스톱퍼내장형 엔진마운트에 관한 것이다.The present invention relates to an engine mount of an automobile, and more particularly, to incorporate an stopper in the shock absorbing member of the engine mount so as to suppress excessive displacement in the axial direction due to vibration, thereby interfering with other parts caused by an excessive displacement in the axial direction. It relates to a stopper built-in engine mount to suppress the.
일반적으로 자동차의 엔진은 작동중 필연적으로 진동을 발생시키는 바, 이와 같은 진동의 원인은 피스톤과 컨넥팅로드의 상하운동에 의한 중심위치의 주기적인 변화와, 실린더 축방향으로 생기는 왕복운동부분에서 발생되는 관성력, 커넥팅로드가 크랭크축의 좌우로 흔들림에 따라 발생되는 관성력 및, 크랭크축에 가해지는 회전력의 주기적인 변화에 따른 것등으로 기인할 수 있다.In general, the engine of an automobile inevitably generates vibrations during operation, and the causes of such vibrations are caused by periodic changes in the center position caused by the vertical movement of the piston and the connecting rod, and reciprocating portions occurring in the axial direction of the cylinder. It may be due to the inertia force generated, the inertia force generated as the connecting rod shakes to the left and right of the crankshaft, and the periodic change of the rotational force applied to the crankshaft.
이에 따라 엔진을 엔진룸내에 탑재시킬 때에는, 진동을 감쇠시켜 승차감을 향상시키기 위해 엔진의 하부에 다수개(통상 3내지 4곳)의 지점으로 적절한 스프링 강성을 지닌 고무로 제작되 엔진마운트를 장착시키고 있는 실정이다.Therefore, when the engine is mounted in the engine room, the engine mount is made of rubber with appropriate spring stiffness at a number of points (usually 3 to 4 places) at the bottom of the engine to damp vibration and improve ride comfort. There is a situation.
그런데, 상기와 같은 목적을 달성하기 위해 사용되는 엔진마운트중에서 부쉬 타입의 엔진마운트는 내측파이프의 외주면에 고무재의 완충부재가 외측파이프와 함께 고착된 형태가 일반적인 것이다.However, among the engine mounts used to achieve the above object, the bush type engine mount is generally in a form in which a cushioning member of rubber material is fixed to the outer circumferential surface of the inner pipe together with the outer pipe.
그리하여 상기와 같은 구조의 부쉬타입의 엔진마운트는, 상기 브라켓트가 차체프레임에 결합되어 고정장착되고, 상기 내측파이프로는 볼트와 같은 체결수단이 끼워져 엔진에 고정된 브라켓트(도시 안됨)와 동시에 체결되어 설치된다.Thus, the bush type engine mount of the above structure is fixed to the bracket is coupled to the vehicle body frame, the inner pipe is fastened at the same time as the bracket (not shown) fixed to the engine by the fastening means such as bolts are fitted Is installed.
그러나 상기와 같이 체결되어 엔진을 지지하는 부쉬타입의 엔진마운트는, 엔진으로부터 전달되는 다양한 진동에 따라 약간씩 유동을 하게 되는데, 특히 유동이 심할 경우에는 과다한 변위로 유동되어 근처에 있는 다른 부품들과 접촉을 하게 되어 금속성의 접촉음을 유발시켜 탑승자의 신경을 거슬리게 되므로 이를 막기 위해서는 엔진마운트를 설치할 때에는 인접된 부품과의 간섭을 방지하기 위해 별도의 장애물을 설치해야 하는 등 간섭에 의해 유발되는 접촉음의 발생소지를 없애는 대책을 강구해야 하는 문제점이 있었다.However, the bush type engine mount that is fastened and supports the engine as described above is slightly flown according to various vibrations transmitted from the engine, especially when the flow is severe, it flows with excessive displacement and other parts nearby. Contact is caused by metallic contact sound, which disturbs the occupant's nerves. To prevent this, contact sound caused by interference, such as installing a separate obstacle to prevent interference with adjacent parts when installing the engine mount, is prevented. There was a problem in that measures should be taken to eliminate the occurrence of the problem.
이에 본 고안은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 엔진을 진동에 따른 엔진마운트의 축방향 과대변위를 억제시켜 타부품과의 간섭이나 접촉등으로 기인되는 마찰음을 방지하도록 엔진마운트의 완충부재내에 스톱퍼를 내장시켜 축방향의 과대변위를 억제시킬 수 있도록 된 스톱퍼 내장형 엔진 마운트를 제공함에 그 목적이 있다.The present invention is devised to solve the above problems, the engine mount cushioning to prevent the friction sound caused by interference or contact with other parts by suppressing the axial over displacement of the engine mount caused by the vibration of the engine It is an object of the present invention to provide a stopper-mounted engine mount in which a stopper is incorporated in the member to suppress excessive displacement in the axial direction.

상기한 바의 목적을 달성하기 위한 본 고안은, 내측파이프 외주면에 탄성력이 있는 고무재의 완충부재가 원통형상의 외측파이프내에 가류접착되는 부쉬타입의 엔진마운트에 있어서, 상기 내측파이프와 외측파이프 사이에 축방향의 대변위를 억제시켜 주도록 된 걸림수단이 구비된 것을 특징으로 한다.The present invention for achieving the above object is a bush type engine mount in which a cushioning member of elastic rubber material on the inner circumferential surface of the inner pipe is vulcanized in a cylindrical outer pipe, the shaft between the inner pipe and the outer pipe. It is characterized in that the locking means is provided to suppress the large displacement in the direction.
이를 위해 상기 걸림수단이 내측파이프의 외주면과 외측파이프의 내주면에서 상호 어긋나게 개재되도록 접합된 판형상의 제1돌출부재와 제2돌출부재인 것을 특징으로 한다.To this end, the locking means is a plate-shaped first protrusion member and a second protrusion member joined so as to be interposed between the outer peripheral surface of the inner pipe and the inner peripheral surface of the outer pipe.
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.
제1도는 본 고안에 따른 스톱퍼내장형 엔진마운트의 단면도이고, 제2도는 제1도의 A-A선 단면도이다.1 is a cross-sectional view of a stopper-mounted engine mount according to the present invention, and FIG. 2 is a cross-sectional view taken along line A-A of FIG.
본 고안의 스톱퍼내장형 엔진마운트는 도면에 도시된 바와 같이, 내측파이프(1)와 완충부재(6)를 매개로 가류접착되는 외측파이프(3)사이에 축방향의 대변위를 억제시켜 주도록 된 걸림수단이 각기 어긋나게 내측파이프(1)와 외측파이프(3)의 외/내주면에 형성되어 이루어지는 바, 즉 내측파이프(1)의 판형태의 제1돌출부재(2)가 소정간격을 두고 이격되어 직립되게 2매 접합되고, 외측파이프(3)의 내주면에는 판형태의 제2돌출부재(4)가 제1돌출부재(2)사이에 개재되도록 직립되게 1매 접합되며, 상기 제1돌출부재(2)의 절단부(5)에 외측파이프(3)와 제2돌출부재(4)를 삽입한 다음 완충부재(6)를 매개로 내측파이프(1)를 가류접착시켜 구성된다.The stopper built-in engine mount of the present invention, as shown in the figure, the locking to restrain the large displacement in the axial direction between the inner pipe (1) and the outer pipe (3) vulcanized adhesively via the buffer member (6) The means are formed on the outer and inner circumferential surfaces of the inner pipe 1 and the outer pipe 3 so as to be shifted from each other, that is, the plate-shaped first protrusion members 2 of the inner pipe 1 are spaced apart at a predetermined interval. Two sheets are joined together, and a single plate-shaped second protruding member 4 is joined to the inner circumferential surface of the outer pipe 3 so as to be interposed between the first protruding members 2, and the first protruding member 2 The outer pipe (3) and the second protruding member (4) is inserted into the cutout portion 5 of the c) and then the inner pipe (1) is subjected to vulcanization bonding through the buffer member (6).
여기서 상기 제1돌출부재(2)의 절단부(5)는 내측파이프(1)와 외측파이프(3)를 완충부재(6)를 매개로 가류접착시킬 때, 내측파이프(1)에 접합된 제1돌출부재(2)와 외측파이프(3)에 접합된 제2돌출부재(4)사이의 간섭이 없이 내측파이프(1)에 외측파이프(3)이 끼워질 수 있는 여유공간이다.Here, the cutout portion 5 of the first protruding member 2 is the first bonded to the inner pipe 1 when the inner pipe 1 and the outer pipe 3 are vulcanized by the buffer member 6. It is a free space in which the outer pipe 3 can be fitted to the inner pipe 1 without interference between the protruding member 2 and the second protruding member 4 bonded to the outer pipe 3.
따라서 상기와 같이 내측파이프(1)와 외측파이프(3)의 외/내주면에 각기 어긋나게 개재되어 접합된 걸림수단을 구비한 엔진마운트는, 엔진의 진동에 따른 대변위시의 상대움직임을 어긋나게 접합된 제1돌출부재(2)와 제2돌출부재(4)사이의 간격내에서만 허용하게 되므로 지나친 엔진마운트의 축방향의 유동을 억제시켜 줄수 있게 되어, 근처에 있는 다른 부품들과의 접촉이 억제될 수 있으므로 금속성의 접촉음이 유발되지 않게 해 준다.Therefore, as described above, the engine mount having the locking means connected to the outer and inner circumferential surfaces of the inner pipe 1 and the outer pipe 3 by shifting the outer pipe 1 and the outer pipe 3, respectively, is made by shifting the relative movement during large displacement caused by the vibration of the engine. Since only the clearance between the first projection member 2 and the second projection member 4 is allowed, it is possible to suppress excessive axial flow of the engine mount, so that contact with other nearby components can be suppressed. Therefore, it does not cause metallic contact sound.
그리고, 본 고안에서 걸림수단으로서 내측파이프(1)의 외주면과 외측파이프(3)의 내주면에서 각기 어긋나게 접합된 제1돌출부재(2)와 제2돌출부재(4)는, 내측파이프(1)와 외측파이프(3)사이의 축방향의 상대움직임을 제한하는 것으로 이의 장착위치나 간격등은 본 고안의 추구하는 목적을 위해 상술한 바와 달리 다양한 형태로 변형되어 실시될 수 있음은 물론이다.In the present invention, the first protrusion member 2 and the second protrusion member 4 joined to the outer circumferential surface of the inner pipe 1 and the inner circumferential surface of the outer pipe 3 as the locking means are respectively the inner pipe 1. The relative position of the axial direction between the outer and the pipe (3) to limit the mounting position or spacing thereof may be implemented in a variety of forms different from those described above for the purpose of the present invention.
이상 설명한 바와 같이 본 고안에 따른 스톱퍼내장형 엔진마운트에 의하면, 엔진의 하부와 차체사이에 고정되어 엔진으로부터 발생된 진동이나 소음 등을 저감시키도록 된 엔진마운트가 엔진의 진동에 따른 대변위시 유발되는 지나친 범위의 축방향 움직임을 내측파이프(1)와 외측파이프(3)의 외/내주면에서 각기 어긋나게 개재되도록 접합된 걸림수단을 매개로 억제시킬 수 있게 됨으로써, 근처의 다른 부품들과 접촉되어 발생되는 금속성의 접촉음이 유발되지 않게 해 주는 효과가 있게 된다.As described above, according to the stopper-embedded engine mount according to the present invention, an engine mount fixed between the lower part of the engine and the vehicle body to reduce vibrations or noise generated from the engine is excessively caused when the displacement of the engine is caused by large displacement. The axial movement of the range can be suppressed by means of the locking means joined to be interposed between the inner and outer circumferential surfaces of the inner and outer pipes 1 and 3, respectively, so that the metallic parts generated in contact with other nearby parts can be suppressed. There is an effect that does not cause the contact sound of.
