Description

공압식 엔진마운트{Air pressure type engine-mount}Pneumatic engine mount {Air pressure type engine-mount}

본 발명은 진동을 저감 시키며 엔진을 차체에 장착시키기 위한 공압식 엔진마운트에 관한 것으로, 더 상세하게는 대변위 진동 및 저변위 진동의 댐핑 효율을 향상시킨 공압식 엔진 마운트에 관한 것이다.
The present invention relates to a pneumatic engine mount for reducing vibration and mounting the engine to a vehicle body, and more particularly, to a pneumatic engine mount for improving the damping efficiency of large displacement vibration and low displacement vibration.

차량의 엔진은 시동 이후 진동을 유발하므로 차체에 장착될 때 엔진마운트에 결합하여 장착된다. 따라서, 엔진마운트는 엔진의 진동을 최대한 억제시키는 것이 주목적으로서 개발되어 왔다.Since the engine of the vehicle causes vibration after starting, it is coupled to the engine mount when mounted on the vehicle body. Therefore, the engine mount has been developed mainly to suppress the vibration of the engine as much as possible.

엔진마운트는 도 1a 내지 도 1c 에 도시된 바와 같이, 러버마운트, 하이드로마운트, 공압식마운트가 있다.Engine mounts are rubber mounts, hydromounts, and pneumatic mounts, as shown in FIGS. 1A-1C.

러버마운트는 인슐레이터 재질자체의 탄성력을 이용하여 댐핑효과를 얻는 구조로서, 센터코어에 엔진하우징이 안착되고 볼트로 고정되면, 엔진진동에 따라 인슐레이터가 탄성변형 및 복원하여 진동을 감쇠시키는 구조이다. 상기 러버마운트는 대변위 진동에 대한 감쇄율은 좋지 않으나, 저변위 진동에 대한 감쇄율은 높은 특성을 나타낸다.The rubber mount is a structure in which the damping effect is obtained by using the elastic force of the insulator material itself. When the engine housing is seated on the center core and fixed with bolts, the rubber mount is elastically deformed and restored according to the engine vibration to damp the vibration. The rubber mount does not have a good attenuation rate for large displacement vibration, but has a high attenuation rate for low displacement vibration.

그리고, 하이드로마운트의 경우 인슐레이터 아래로 내부에 유액이 봉입된 구조로서, 유액이 상측액실과 하측액실을 유동함에 따라 댐핑력을 발생시킨다. 상측액실은 인슐레이터 아래로 노즐 위에 형성된 공간이며, 하측액실은 노즐 아래로 다이어프램 사이에 형성된 공간이다. 봉입된 유액는 노즐에 형성된 유로 또는 맴브레인이 형성된 공간을 경로로 유동하되, 각 경로에 따라서 고주파 진동(저변위 진동) 및 저주파 진동(대변위 진동)을 감쇄시키도록 구성된다. 다만, 유액의 점성 및 유동저항에 의해 고주파 동특성은 러버마운트 보다 효과적이지 못한 측면이 있다.In addition, in the case of the hydromount, the fluid is sealed under the insulator, and the damping force is generated as the fluid flows through the upper liquid chamber and the lower liquid chamber. The upper liquid chamber is a space formed above the nozzle under the insulator, and the lower liquid chamber is a space formed between the diaphragms below the nozzle. The encapsulated fluid flows through a path in which a flow path or a membrane formed in the nozzle is formed, and is configured to attenuate high frequency vibration (low displacement vibration) and low frequency vibration (large displacement vibration) according to each path. However, due to the viscosity and flow resistance of the fluid, high frequency dynamics are less effective than rubber mounts.

도 1c 에 도시된 공압식 마운트는, 인슐레이터 재질 자채의 탄성력 및 공기를 작동유체로 유동시켜 댐핑력을 얻는 구조로서, 하우징 내부에는 인슐레이터가 부설되되, 하부에 밑판이 장착되어 챔버를 구성하고 인슐레이터의 탄성변형에 따라 챔버로 공기가 출입되도록 에어홀이 형성되어 있다. 공압식마운트는 비교적 제조가 용이하여 소형 승용차에 주로 사용되고 있다.
The pneumatic mount shown in FIG. 1c has a structure in which the elastic force of the insulator material and the air flow into the working fluid to obtain a damping force. An insulator is installed inside the housing, and a bottom plate is mounted at the bottom to form a chamber and the elasticity of the insulator. Air holes are formed to allow air to enter and exit the chamber according to the deformation. Pneumatic mounts are relatively easy to manufacture and are mainly used in small passenger cars.

한편, 하이드로마운트의 경우, 진동 특성에 따라 유액이 가변적으로 유동하며 진동을 감쇠시키나, 공압식 마운트는 에어홀의 직경이 고정되어 진동 특성에 따라 감쇄 효율이 상이하게 나타나는 문제가 있었다.On the other hand, in the case of hydromount, the fluid flows in accordance with the vibration characteristics to attenuate the vibration, but the pneumatic mount has a problem that the attenuation efficiency is different depending on the vibration characteristics because the diameter of the air hole is fixed.

본 발명은, 대변위 진동 및 저변위 진동에 상관없이 더 효율적인 진동 감쇄력을 제공하는 공압식 엔진마운트를 제공하는 것에 주목적이 있다.
The present invention is directed to providing a pneumatic engine mount that provides more efficient vibration damping force regardless of large displacement and low displacement vibration.

상기와 같은 목적을 달성하기 위한 본 발명은, 차량의 엔진을 지지하는 공압식 엔진마운트에 있어서, 엔진에 결합되는 센터코어가 상측으로 결합되고 하부는 개구된 하우징;과 상기 하우징 내부에 수용되어 센터코어의 하부와 결합되고 하부면이 오목하게 형성된 인슐레이터;와 상기 인슐레이터의 아래로 하우징의 하단에 결합되어 챔버를 형성하고 상기 챔버로 공기가 출입하도록 에어홀이 형성된 밑판; 및 상기 밑판의 아래로 결합되는 지지판;을 포함하고, 상기 밑판은 하우징에 고정된 고정부와 에어홀이 형성된 진동부 및 상기 고정부와 진동부를 연결하며 공기의 출입에 따라 탄성변형하는 탄성부로 구성되되, 상기 진동부와 지지판 사이에는 일정한 간극(間隙)을 형성하고 스토퍼가 부설된 것을 특징으로 한다.The present invention for achieving the above object, in the pneumatic engine mount for supporting the engine of the vehicle, the center core coupled to the engine is coupled to the upper side and the lower housing; and the center core is accommodated in the housing An insulator coupled to a lower portion of the insulator and having a concave bottom surface; and a bottom plate coupled to a lower end of the insulator to form a chamber, and an air hole formed to allow air to enter and exit the chamber; And a support plate coupled to the bottom of the bottom plate, wherein the bottom plate includes a vibration part formed with a fixed part and an air hole fixed to the housing, and an elastic part that connects the fixing part and the vibration part and elastically deforms as the air enters and exits. However, a certain gap is formed between the vibrator and the support plate, and a stopper is provided.

상기 진동부는 중심에 에어홀이 형성된 원판형상이며, 탄성부는 진동부가 내주면에 결합되는 링 형상이고, 지지판는 탄성부가 내주면에 결합되는 링 형상으로 이뤄진다.The vibrating portion is a disk shape having an air hole in the center, the elastic portion is a ring shape is coupled to the inner peripheral surface of the vibration portion, the support plate is made of a ring shape is coupled to the inner peripheral surface.

그리고, 상기 스토퍼는 탄성부와 일체로 형성되어 진동부의 하부면에 밀착되도록 배치된다.
The stopper is integrally formed with the elastic part and disposed to be in close contact with the lower surface of the vibrating part.

상기와 같은 구성의 본 발명은, 저변위 진동시 챔버로 유입되는 공기의 저항을 탄성부가 상쇄시킴으로서 저변위 진동에 대한 감쇄율을 향상시키며, 스토퍼가 밑판의 변위를 단속함으로서 대변위 진동시에도 감쇄율을 향상시키는 효과가 있다.
According to the present invention, the elastic part cancels the resistance of the air flowing into the chamber during the low displacement vibration, thereby improving the attenuation rate for the low displacement vibration, and the stopper interrupts the displacement of the base plate, thereby reducing the attenuation rate during the large displacement vibration. It is effective to improve.

이하, 도면을 참조하여 본 발명의 바람직한 실시예들을 더욱 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2 를 참조하면, 본 발명의 공압식 엔진마운트는 엔진을 거치하기 위해 차체에 장착되며, 센터코어(60) 및 볼트(70)가 하우징(50) 상측에 돌출되고 내부에는 인슐레이터(40)가 장착된다. 상기 인슐레이터(40)는 합성고무재로서 엔진의 진동에 따라 탄성변형하며, 인슐레이터(40)의 하단에는 밑판(10: 10a, 10b, 10c)이 장착되어 챔버를 형성한다. 2, the pneumatic engine mount of the present invention is mounted to the vehicle body for mounting the engine, the center core 60 and the bolt 70 protrudes above the housing 50 and the insulator 40 is mounted therein. do. The insulator 40 is a synthetic rubber material and elastically deformed according to the vibration of the engine. The bottom plate 10: 10a, 10b, and 10c are mounted on the lower end of the insulator 40 to form a chamber.

상기 밑판(10)에는 에어홀(12)이 형성되어 하부면이 오목하게 형성된 인슐레이터(40)의 탄성변형에 따라 챔버 내에 양압(대기압보다 높은 압력) 및 부압(대기압보다 낮은 압력)이 반복적으로 형성되어 공기가 출입한다. In the bottom plate 10, an air hole 12 is formed, and positive pressure (higher than atmospheric pressure) and negative pressure (lower than atmospheric pressure) are repeatedly formed in the chamber according to the elastic deformation of the insulator 40 having the lower surface concave. Air enters.

상기 밑판(10)은 원판형 형상이되, 중심은 인슐레이터(40)의 바닥면에 근접하도록 돌출된 형태로 형성된다. 상기 밑판은, 컬링(curling)된 하우징(50)의 끝단에 맞물려 고정되는 고정부(10b)와 중심에 에어홀(12)이 형성된 진동부(10a) 및 상기 고정부(10b)와 진동부(10a)를 연결하며 탄성변형 가능한 탄성부(10c)로 이뤄진다. The base plate 10 has a disc shape, the center of which is formed to protrude to the bottom surface of the insulator 40. The bottom plate may include a vibrating portion 10a having an air hole 12 formed at a center thereof and a fixed portion 10b fixed to an end of a curled housing 50, and the fixing portion 10b and a vibrating portion ( It connects 10a) and consists of an elastically deformable elastic portion 10c.

상기 하우징(50)은 원기둥 형상으로 형성되므로, 상기 진동부(10a)는 원판 형상으로 형성되고 고정부(10b)와 탄성부(10c)는 링(ring) 형상으로 형성된다. 그리고, 탄성부(10c)는 재질의 특성 및 마운트 설계요건에 따라 도시된 바와 같이 홈(groove)이 형성될 수 있다. Since the housing 50 is formed in a cylindrical shape, the vibration part 10a is formed in a disc shape, and the fixing part 10b and the elastic part 10c are formed in a ring shape. In addition, the elastic portion 10c may have a groove formed as shown in accordance with the characteristics of the material and the mount design requirements.

아울러, 진동부(10a)의 아래로는 탄성재질의 스토퍼(13)가 부착된다. 상기 스토퍼(13)는 대변위 진동 입력시 진동부(10a)의 과도한 요동을 단속하기 위한 것으로서, 밑판 하부에 장착되는 지지판(30)과는 일정 간극을 두고 장착된다. 상기와 같은 목적으로 부설된 스토퍼(13)는 일정 간극을 형성하고 진동부(10a)가 아닌 지지판(30)의 상면에 장착될 수도 있다. 그리고 상기 지지판(30)에는 챔버로의 공기 출입에 간섭을 발생시키지 않도록 통기홀(31)이 형성된다. 상기 통기홀(31)은 에어홀(12) 보다 더 크게 형성되는 것이 바람직하다.In addition, an elastic stopper 13 is attached below the vibrator 10a. The stopper 13 is for controlling excessive swinging of the vibrator 10a during large displacement vibration input, and is mounted with a predetermined gap from the support plate 30 mounted below the bottom plate. The stopper 13 disposed for the above purpose may form a predetermined gap and may be mounted on the upper surface of the support plate 30 instead of the vibrator 10a. In addition, the support plate 30 is provided with a ventilation hole 31 so as not to cause interference in the air in and out of the chamber. The vent hole 31 is preferably formed larger than the air hole 12.

본 발명의 다른 실시예에 따른 밑판(20)의 모습은 도 3 에 도시되었다. 스토퍼 및 탄성부는 탄성을 갖는 재질이므로 일체로 형성될 수 있다. 즉, 링 형상의 탄성부(23)를 진동부(25)의 테두리가 거치될 수 있도록 형성하고, 바닥면에 스토퍼(24)를 일체로 돌출형성시켜 구성할 수 있다. The appearance of the base plate 20 according to another embodiment of the present invention is shown in FIG. 3. The stopper and the elastic part may be integrally formed because the material has elasticity. That is, the ring-shaped elastic portion 23 may be formed so that the rim of the vibrator 25 may be mounted, and the stopper 24 may be integrally formed to protrude from the bottom surface.

그리고, 참고적으로, 하우징(50)의 끝단을 컬링하지 않고 (용접 또는 볼트 체결 등과 같은) 별도의 다른 방식으로 밑판(20) 및 지지판(30)이 결합되는 경우, 고정부(21)에는 하우징(50)이 끼움맞춤될 수 있도록 플랜지(22)를 형성하여 구성될 수 있다.And, for reference, when the bottom plate 20 and the support plate 30 are coupled in a different manner (such as welding or bolting) without curling the ends of the housing 50, the fixing portion 21 is attached to the housing. It can be configured to form a flange 22 so that 50 can be fitted.

상기와 같은 구성의 본 발명은, 저변위 진동시에도 효과적인 댐핑이 이뤄질 뿐만아니라 대변위 진동시에도 진동부의 과도한 움직임을 단속하여 댐핑효과가 저하되는 문제점을 방지한다. 도 4 의 그래프에 도시된 바와 같이 본 발명을 적용한 공압식 엔진마운트는 종래의 방식과 대비하여 대변위 진동발생시 댐핑력은 향상시키고 저변위 진동발생 시 동특성을 낮추는 효과를 가져온다. The present invention having the above configuration prevents the problem that the damping effect is lowered by controlling the excessive movement of the vibrator even in the case of the low displacement vibration as well as the effective damping. As shown in the graph of FIG. 4, the pneumatic engine mount to which the present invention is applied has an effect of improving the damping force when the large displacement vibration occurs and lowering the dynamic characteristics when the low displacement vibration occurs in comparison with the conventional method.

이상과 같이 본 명세서와 도면에 개시된 실시예들은 본 발명의 이해를 돕기 위해 특정 예를 제시한 것에 지나지 않으며, 본 발명의 범위를 제한하고자 하는 것은 아니다. 여기에 개시된 실시예들 이외에도 본 발명의 기술적 사상에 바탕을 둔 다른 변형예들이 실시 가능하다는 것은 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에게 자명한 것이다.
