Abstract
본 발명은 자동차의 기관에서 발생된 진동이 차체를 통해 실내쪽으로 전달되는 것을 효율적으로 차단하도록 하기 위해, 차체의 양쪽 저면부에 위치되고 선단부 사이에 기관(20)이 마운팅되는 프레임(14) 선단부 내부에 자연경화용 발포포움(40)이 내장되도록 하여, 차량의 제작시 프레임(14)의 밀폐된 폐단면 내부에 자연경화용 발포포움(40)을 주입하면 소정 시간이 경과한 후 발포포움(40)의 부피가 팽창되어 기관(20)의 마운팅부 프레임(14) 내부에 기밀하게 밀착되며, 기관(20)의 작동시 마운팅부인 브라켓(21)을 통해 프레임(14)과 차체로 전달되는 진동이 프레임(14)의 박스 내부에서 공진되고 발포포움(40)에 의해 공진되는 진동 및 소음이 흡수되도록 하는 소음 저감용 차체의 구조이다.In order to effectively block the vibrations generated in an engine of an automobile from being transmitted to a room through a vehicle body, the present invention is applied to a structure in which a front end portion of a frame (14), which is located at both bottom portions of a vehicle body, The natural curing foaming foam 40 is embedded in the sealed closed end face of the frame 14 when the vehicle is manufactured so that the foam cushion 40 The vibration transmitted to the frame 14 and the vehicle body through the bracket 21 which is the mounting portion during operation of the engine 20 is transmitted to the vehicle body 20 And a structure for a noise reduction body to allow vibration and noise resonated inside the box of the frame 14 and resonated by the foam foam 40 to be absorbed.
