Description

엔진마운팅의 유체방진러버 구조Fluid Antivibration Rubber Structure of Engine Mounting

본 발명은 자동차의 엔진마운팅에 관한 것으로, 특히 내부에 유체를 봉입하여 러버의 움직임에 따라 유체의 유동이 발생하면서 이 유체가 가동판을 통과하면서 에너지손실을 유발하게 되어 방전성능이 향상되도록 된 엔진마운팅의 유체방진러버 구조에 관한 것이다.The present invention relates to an engine mounting of an automobile, and in particular, an engine in which a fluid flows in accordance with the movement of a rubber by enclosing a fluid therein, causing the fluid to lose energy while passing through a movable plate, thereby improving discharge performance. The present invention relates to a fluid vibration resistant rubber structure of a mounting.

일반적으로, 운전중의 엔진은 피스톤과 컨로드의 상하운동에 의한 중심위치의 주기적 변화와, 실린더 축방향으로 생기는 왕복운동 부분의 관성력과, 커넥팅 로드가 크랭크 축의 좌우로 흔들리는 것에 의한 관성력과, 크랭크 축에 가해지는 회전력의 주기적인 변화 등의 원인으로 항상 진동하게 되는데, 이때 상기 진동 등이 섀시나 보디에 전해져 승차감이 나빠지지 않도록 엔진 장착부에는 반드시 탄성체에 의한 방진장치가 설치되어지는데 그 구조는 도3에 도시된 바와 같이, 탄성력이 있는 러버부(44)가 내부의 공간으로 채워진 외측파이프(33)와, 상기 러버부(44)의 중심에 원형의 관통홀로 이루어진 내측파이프(55)로 구성되어져 엔진쪽과 바디쪽으로 연결되어진다.In general, the engine during operation has a periodic change in the center position due to the vertical movement of the piston and the conrod, the inertia force of the reciprocating portion occurring in the cylinder axial direction, the inertia force due to the connecting rod swinging from the left and right of the crank shaft, and the crank. Due to the periodic change in rotational force applied to the shaft, the vibration always occurs. At this time, the vibration is transmitted to the chassis or the body so that the engine mounting part is always equipped with an anti-vibration device by an elastic body. As shown in FIG. 3, the elastic rubber part 44 is composed of an outer pipe 33 filled with an inner space, and an inner pipe 55 formed of a circular through hole at the center of the rubber part 44. It is connected to the engine side and the body side.

따라서, 상기 러버부(44)가 압축, 인장, 비틀림 등의 작용을 함에 따라 상기 진동, 소음등을 흡수하도록 된다.Accordingly, the rubber part 44 absorbs the vibration, the noise, etc. as the compression, tension, and torsion acts.

그러나, 상기 방진러버 구조는 시동을 걸때나, 중/고속 주행시에 방진러버의 에너지 손실율이 미약하여 방진성능이 저하되는 문제점이 있었다.However, the dustproof rubber structure has a problem in that the dustproof performance is deteriorated due to a weak energy loss rate of the dustproof rubber at start-up or at medium / high speed driving.

이에 본 발명은 상기와 같은 제반 문제점을 해소하기 위해 발명된 것으로, 외측파이프 안측에 유체를 봉입하여 외측파이프에 설치되어진 가동판을 통해 유체가 통과하면서 엔진의 어떠한 진동에도 에너지손실을 가져다주어 방진성능이 향상되는 엔진마운팅의 유체방진러버 구조를 제공함에 그 목적이 있다.Accordingly, the present invention is invented to solve the above problems, the fluid is enclosed in the inner side of the outer pipe and the fluid passes through the movable plate installed in the outer pipe while bringing energy loss to any vibration of the engine, dustproof performance It is an object to provide a fluid dustproof rubber structure of this improved engine mounting.

상기와 같은 목적을 달성하기 위한 본 발명은, 외측파이프내에 삽입단 및 지지단에 의해서 연결되어지는 가동판이 상/하 2곳에 설치되어져 양측 삽입단 및 지지단을 매개로 유동하게 되며, 이 가동판의 상면으로 지지단의 일단에 취부되어지는 다이아그램은 원주방향으로 탄성을 갖도록 휘어지게 된다.The present invention for achieving the above object, the movable plate which is connected by the insertion end and the support end in the outer pipe is installed in the upper / lower two places and flows through both the insertion end and the support end, the movable plate The diagram attached to one end of the support end to the upper surface of the bent is bent to have elasticity in the circumferential direction.

이에따라, 외측파이프내에 봉입된 유체가 상기 가동판의 상/하로 지나가게 되면서 가동판의 유동이 발생되어 에너지 손실을 일으키게 되고 이때 상기 다이아그램은 유체가 가동판을 통하여 내려오게 되면서 신축성있게 움직이게 된다.Accordingly, as the fluid enclosed in the outer pipe passes up and down the movable plate, flow of the movable plate is generated to cause energy loss, and the diagram moves elastically as the fluid descends through the movable plate.

이하, 본 발명을 예시된 도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the illustrated drawings.

도 1은 본 발명에 따른 엔진마운팅부를 도시한 것이고, 도 2는 본 발명에 따른 도 1의 A-A 선의 단면을 도시한 것이며, 도 3은 본 발명에 따른 엔진마운팅의 에너지손실율을 도시한 것인 바, 본 발명은, 좌/우 양측면에 유격홈이 형성되어진 대략 직사각형상으로 성형되어진 가동판(3a)과, 상기 유격홈으로 연결되어 상기 가동판(3a)을 원통의 외측파이프(3e)에 취부되도록 하는 지지단(3c)과, 상기 가동판(3a)의 상면에 위치되어 지지단(3c)의 삽입단(3d)을 매개로 원주방향으로 활처럼 고정되어지는 다이아그램(3b)과, 상기 외측파이프(3e)의 중심부에 작은 원형의 홀로 관통되어진 내측파이프(3f)와, 상기 내측파이프(3f)와 외측파이프(3e)사이에 탄성력이 있는 고무등으로 채워진 방진러버(3g)로 구성되어진다.1 illustrates an engine mounting unit according to the present invention, FIG. 2 illustrates a cross section of the AA line of FIG. 1 according to the present invention, and FIG. 3 illustrates an energy loss rate of the engine mounting according to the present invention. In the present invention, the movable plate 3a is formed in a substantially rectangular shape in which a clearance groove is formed on both left and right sides thereof, and the movable plate 3a is attached to the cylindrical outer pipe 3e by being connected to the clearance groove. And a diagram 3b which is located on the upper surface of the movable plate 3a and which is fixed like a bow in the circumferential direction via the insertion end 3d of the support end 3c. It consists of an inner pipe 3f penetrated by a small circular hole in the center of the outer pipe 3e, and an anti-vibration rubber 3g filled with rubber or the like with elastic force between the inner pipe 3f and the outer pipe 3e. Lose.

이때, 상기 외측파이프(3e) 내부의 빈공간은 유체로 채워져 밀봉되어진다.At this time, the empty space inside the outer pipe 3e is filled with a fluid and sealed.

따라서, 차체의 흔들림, 중/고속주행 등의 원인으로 엔진의 진동이 일어날 때에, 엔진마운팅 외측파이프(3e)의 유체가 상기 가동판(3a)의 상/하로 지나가게 되면서 가동판(3a)이 지지단(3c)을 매개로 유동하게 되어 에너지 손실(도3에 도시된 선도에서 빗금친 부분만큼)을 일으키게 되므로 상기 엔진의 진동 등이 감쇄되어지는데 이때 상기 다이아그램(3b)은 유체가 가동판을 지나서 내려오게 되면 신축성있게 상/하로 움직이게 된다.Therefore, when the engine vibrates due to the shaking of the vehicle body, the medium / high speed driving, etc., the fluid of the engine mounting outer pipe 3e passes up / down of the movable plate 3a while the movable plate 3a Since the fluid flows through the support end 3c, it causes energy loss (as much as the hatched portion in the diagram shown in FIG. 3), so that the vibration of the engine and the like are attenuated. If you go down past the elastic will move up and down.

이상 설명한 바와 같이 본 발명에 의하면, 외측파이프 안측에 유체를 봉입하여 외측파이프에 설치되어진 가동판을 통해 유체가 통과하면서 엔진의 어떠한 진동에도 에너지손실을 가져다주어 방진성능이 향상되는 효과가 있다.As described above, according to the present invention, the fluid is enclosed in the inner side of the outer pipe and the fluid passes through the movable plate provided on the outer pipe, bringing energy loss to any vibration of the engine, thereby improving dustproof performance.

이상에서 설명한 것은 본 발명에 의한 엔진마운팅의 유체방진러버 구조를 실시하기 위한 하나의 실시예에 불과한 것으로, 이하 청구범위내에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경실시가 가능할 것이다.What has been described above is only one embodiment for implementing the fluid vibration-proof rubber structure of the engine mounting according to the present invention, which is conventional in the field to which the present invention pertains without departing from the spirit of the invention as claimed in the following claims.
