Description

콘 타입의 에어댐핑 엔진마운트{cone typic air damping engin mount}Cone typic air damping engin mount

본 발명은 콘 타입의 에어댐핑 엔진마운트에 관한 것이다.The present invention relates to a cone type air damping engine mount.

일반적으로, 자동차의 로워암과 같은 운동부나 엔진과 같은 구동부에 설치되는 방진부재 즉, 마운트는 서스펜션 또는 엔진의 차체측 연결부위를 받쳐주는 구조적 측면에서의 역할과 함께 자체 탄성변형을 이용하여 서스펜션이나 엔진에서 발생되는 충격, 진동, 소음 등을 흡수하는 역할을 한다.In general, a dustproof member, that is, a mount installed in a moving part such as a lower arm of an automobile or a driving part such as an engine, has a role in suspension or a structural aspect supporting the connection part of the engine body, and uses a suspension or its own elastic deformation. It absorbs shock, vibration and noise generated from the engine.

일반적으로 이러한 마운트는 종래부터, 진동전달계를 구성하는 부재 사이에 개재되어, 진동의 전달을 제어하는 작용을 하며, 이를 위해, 진동입력방향으로 소정 거리를 이격시켜 배치된 제 1의 지지체와 제 2의 지지체를 이들 사이에 개재된 고무탄성체로 연결시켜 이루어진 구조로 되어 있다.In general, such a mount is interposed between members constituting the vibration transmission system to control the transmission of vibration. For this purpose, the first support and the second support are arranged to be spaced a predetermined distance in the vibration input direction. It is a structure made by connecting the support body with the rubber elastic body interposed between them.

이러한 마운트는 그 진동 감쇠 범위나 기능의 한계성 때문에 최근에는 액상의 유체 봉입형 마운트가 널리 채용되고 있다.These mounts have recently been widely adopted liquid-liquid mounts because of their vibration damping range and their limited functionality.

특히, 주행중 휠(wheel)로부터 전달되는 진동을 감쇠하는 유체 봉입형 마운트는 고무재로 형성된 방진체의 내부에 액실을 구비하고, 상기 액실 내에는 비압축성인 액상의 유체를 충전하여 기하학적 오리피스를 결정함으로써 원하는 주파수 대 역에서 발생되는 종 방향의 진동을 액상의 유체에 의한 유동을 이용하여 흡수할 수 있도록 되어 있다.In particular, a fluid-enclosed mount that attenuates vibration transmitted from a wheel while driving has a liquid chamber inside a dustproof body formed of a rubber material, and inside the liquid chamber is filled with an incompressible liquid fluid to determine a geometric orifice. The longitudinal vibration generated in the desired frequency band can be absorbed by the flow of the liquid fluid.

하지만, 이러한 액상의 유체는 고가이어서, 마우트 제조 비용을 상승시킨다고 하는 문제가 있다.However, there is a problem that such a liquid fluid is expensive, thereby increasing the manufacturing cost of the mout.

이러한 문제를 극복하기 위해서, 액상의 유체를 대신하여 기체인 공기를 이용하는 방안이 고려되고 있으며, 현재 상기 방진체의 바닥 부근에 외부와 유통하는 압축챔버를 외곽 틀과 협력하여 구획형성하여, 상기 방진체의 종방향 진동에 따른 압축챔버의 공간 수축/확장에 따라 상기 압축챔버에 외기(공기)가 유입/유출하게 되는 콘 타입의 마운트가 출시되고 있다. In order to overcome this problem, a method of using air, which is a gas instead of a liquid, is being considered, and at present, a compression chamber circulating with the outside near the bottom of the dustproof body is formed in cooperation with an outer frame to form the dustproof device. Cone-type mounts are introduced in which outside air (air) flows into and out of the compression chamber according to the space contraction / expansion of the compression chamber according to the longitudinal vibration of the sieve.

하지만, 상기 공기가 무상으로 외부에서 얼마든지 얻을 수 있어서, 에어 마운트의 제조비용을 낮추지만, 상기 공기가 압축성이기 때문에, 종래의 에어 마운트는 진동에 신속하게 반응하지 못한다고 하는 문제점이 있다.However, the air can be obtained free of charge from the outside, thereby lowering the manufacturing cost of the air mount. However, since the air is compressible, the conventional air mount does not respond quickly to vibration.

이러한 문제점을 해결하기 위해, 종래의 에어 마운트는 상기 방진체와 외곽 틀에 구획형성된 압축챔버의 높이를 축소시키고 외경을 확장시킴으로써 진동에 어느정도 신속하게 반응하게 되지만, 이 역시 진동에 대한 반응속도가 늦고 에어 마운트의 전체적인 크기가 확대된다고 하는 문제점이 있다.In order to solve this problem, the conventional air mount responds to the vibration to some extent quickly by reducing the height of the compression chamber defined in the dustproof body and the outer frame and expanding the outer diameter, but this also slows the response speed to the vibration. There is a problem that the overall size of the air mount is enlarged.

본 발명은 상기된 문제점을 해결하는 것에 해결하고자 하는 과제를 가지고 있다.The present invention has a problem to be solved in solving the above problems.

본 발명은, 외기에 대하여 차단된 압축챔버 그리고 이 압축챔버와 유통가능한 팽창챔버가, 방진체와 외곽 틀에 의해 구획형성된, 콘 타입의 엔진마운트에 에어댐핑을 제공함으로써, 상기 과제를 달성할 수 있다.The present invention can achieve the above object by providing air damping to a cone-type engine mount, in which the compression chamber and the expansion chamber circulated with the compression chamber, which are blocked against the outside air, are partitioned by the dustproof body and the outer frame. have.

상기와 같은 과제 해결 수단에 의해 본 발명은 콘 타입의 엔진마운트에 고가인 액상의 유체 대신에 공기를 적용하여 엔진마운트의 제조비용을 낮춤과 동시에 압축성의 공기로 인한 진동에 대한 낮은 감쇄 반응성을 신속하게 하는 것을 가능하게 한다. According to the above-described problem solving means, the present invention applies air instead of expensive liquid fluid to the cone-type engine mount, thereby lowering the manufacturing cost of the engine mount and at the same time rapidly reducing the attenuation responsiveness to vibration caused by the compressible air. Makes it possible to
