이 고안은 전기유동유체(Electrical Rheological Fluid)를 이용한 엔진(Engine) 진동감쇄장치에 관한 것으로서, 더 상세하게 말하면, 자동차의 엔진에서 프레임(Frame)을 통해 차체로 전달되는 진동을 전기유동유체를 이용하여 감쇄시키는 장치에 관한 것이다.The present invention relates to an engine vibration attenuation apparatus using electric rheological fluid, and more specifically, an electric fluid is used for vibration transmitted from a vehicle engine to a vehicle body through a frame. It relates to a device for attenuating.
일반적으로 자동차 주행 도로의 상태나 엔진 등의 기계적인 장치의 동작 등으로, 자동차가 주행할 경우나 정차할 경우에 많은 진동과 소음이 발생한다.In general, a lot of vibration and noise are generated when the vehicle runs or stops due to the condition of the driving road, the operation of a mechanical device such as an engine, or the like.
이와 같은 소음이나 진동이 프레임을 통해 차체로 전달되어 탑승자의 승가감을 감소시키는 현상을 줄이기 위해, 현가 장치를 장착하여 주행 상태에 따라 발생하는 진동이나 충격을 흡수하고 진폭을 감쇄시킬 수 있도록 한다. 또 엔진이나 변속기 등의 자동차 기계 장치에서 발생하는 진동이 역시 프레임을 통해 곧바로 차체로 전달되는 것을 방지하기 위해 진동이 많이 발생하는 엔진이나 변속기 등과 프레임 사이에 고무(Rubber) 등을 이용한 마운터(mounter)를 장착하고 차체로 전달되는 진동을 줄일 수 있도록 한다.In order to reduce the phenomenon that the noise or vibration is transmitted to the vehicle body through the frame to reduce the riding feeling of the occupant, the suspension device is mounted to absorb the vibration or shock generated according to the driving state and to reduce the amplitude. In addition, a mounter using rubber or the like between an engine or a transmission and a frame in which vibration is generated in order to prevent vibrations generated from an automobile mechanical device such as an engine or a transmission from being directly transmitted to the vehicle body. To reduce the vibration transmitted to the bodywork.
그러나 프레임과 엔진 사이에 장착한 상기 종래의 고무를 이용한 마운터는 일정한 강성(stiffeness)을 가지고 있어 특정 주파수 영역에서만 진동을 감쇄한다는 문제점이 있다.However, the conventional rubber mounter mounted between the frame and the engine has a certain stiffness and thus attenuates vibration only in a specific frequency region.
따라서 이 고안의 목적은 상기 문제점을 해결하기 위한 것으로, 엔진으로부터 프레임으로 전달되는 진동을, 프레임과 엔진 사이에 장착된 전기유동유체의 강성을 제어함으로써 넓은 범위에서 감쇄시키는, 전기유동유체를 이용한 엔진 진동감쇄장치를 제공하는 것이다.Therefore, an object of the present invention is to solve the above problems, and to reduce the vibration transmitted from the engine to the frame in a wide range by controlling the stiffness of the electrofluid fluid mounted between the frame and the engine, the engine using the electrofluid fluid It is to provide a vibration damping device.
