본 고안은 자동차의 차체구조에 관한 것으로서, 특히 변속기에서 발생되는 소음을 효과적으로 흡음하도록 하고, 흡음재의 교환이 용이하도록 하는 자동차의 변속기 흡음구조에 관한 것이다.The present invention relates to a vehicle body structure, and more particularly to a transmission sound absorbing structure of a vehicle to effectively absorb the noise generated in the transmission, and to facilitate the replacement of the sound absorbing material.
종래, 자동차의 변속기 흡음구조는 제1도에 도시되는 바와 같이, 변속기(1) 양쪽에 소정의 간격을 두고 프레임(frame)(2)이 위치되고, 프레임(2) 상부에 변속기(1)가 위치되는 중앙부가 상부로 돌출되도록 절곡형성된 플러어판넬(floor panel)(3)이 설치되며, 양쪽의 프레임(2) 내측면에 각기 다공질판의 흡음재(4)가 브래킷(bracket)(5)에 의해 부착되어 있다.Conventionally, in the transmission sound absorbing structure of a vehicle, as shown in FIG. 1, the frame 2 is positioned at predetermined intervals on both sides of the transmission 1, and the transmission 1 is disposed on the frame 2. A floor panel (3) is bent and formed so that the central portion of the center portion protrudes upward, and the sound absorbing material (4) of each porous plate is attached to the bracket (5) on the inner surfaces of both frames (2). It is attached by.
이와같이 구성되는 종래 변속기의 흡음구조는, 변속기(1)에서 발생되는 소음이 플로어 판넬(3)에 의해 차단되고, 흡음재(4)의 다공을 통해 흡수되어 상쇄되도록 되어 있으나, 흡음재(4)가 브래킷(5)에 일체로 부착되어 흡음효과가 만족스럽지 못하였고, 착탈이 용이하지 않은 문제점이 있었다.In the sound absorbing structure of the conventional transmission configured as described above, the noise generated in the transmission 1 is blocked by the floor panel 3 and is absorbed through the pores of the sound absorbing material 4 to be offset, but the sound absorbing material 4 is bracketed. Attached integrally to (5), the sound absorbing effect was not satisfactory, and there was a problem in that the detachment was not easy.
본 고안의 목적은 상기와 같은 종래의 문제점을 해결하기 위해, 흡음재 및 브래킷 사이에 스페이서(spacer)가 위치되도록 하고, 체결부재에 의해 흡읍재를 브래킷에 취부하여, 변속기에서 발생되는 소음을 효과적으로 흡수하도록 하는 자동차의 변속기 흡음구조를 제공하는데 있다.An object of the present invention is to solve the conventional problems as described above, so that the spacer (spacer) is located between the sound absorbing material and the bracket, by mounting the suction material to the bracket by the fastening member, to effectively absorb the noise generated in the transmission It is to provide a transmission sound absorbing structure of a vehicle.
이하 첨부된 도면에 의하여 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail.
본 고안도 변속기 양쪽에 소정의 간격을 두고 프레임(frame)(2)이 위치되고, 프레임(2) 상부에 변속기가 위치되는 중앙부가 상부로 돌출되도록 절곡형성된 플로어판넬(floor panel)이 설치되며, 각 프레임(2) 내측면에 다공질판의 흡음재(4)가 브래킷(bracket)(5)에 의해 부착되는 것은 종래와 같다. 단, 본 고안은 제2도에 도시되는 바와 같이, 흡음재(4) 및 브래킷(5)에 서로 연통되는 체결구멍이 형성되고, 브래킷(5)과 흡음재(4) 사이에 스페이서(6)가 체결구멍 부위에 부착되어, 상기 체결구멍으로 관통되는 체결부재(7)에 의해 흡음재(4)가 브래킷(5)에 취부됨을 그 기술적 구성상의 기본 특징으로 한다.In the present invention, the frame 2 is positioned at both sides of the transmission at predetermined intervals, and the floor panel bent so as to protrude upward from the center portion in which the transmission is positioned above the frame 2 is installed. The sound absorbing material 4 of the porous plate is attached to the inner surface of each frame 2 by the bracket 5 as in the prior art. However, according to the present invention, as shown in FIG. 2, a fastening hole is formed in the sound absorbing material 4 and the bracket 5 to communicate with each other, and the spacer 6 is fastened between the bracket 5 and the sound absorbing material 4. The sound absorbing material 4 is attached to the hole, and the sound absorbing material 4 is attached to the bracket 5 by the fastening member 7 penetrating through the fastening hole.
이와같이 구성되는 본 고안은, 흡음재(4)와 브래킷(5)의 체결구멍이 스페이서(6)의 중심부 구멍과 연통되도록 하고, 체결구멍으로 체결부재(7)를 삽입하여 고정하므로, 흡음재(4)와 브래킷(5) 사이에 소정의 간격이 형성되도록 한다.The present invention constituted as described above allows the fastening holes of the sound absorbing material 4 and the bracket 5 to communicate with the central hole of the spacer 6, and inserts and fastens the fastening member 7 to the fastening holes, thereby absorbing the sound absorbing material 4. And a predetermined gap is formed between the bracket 5 and the bracket 5.
이러한 본 고안은, 스페이서(6)의 두께 만큼 간격이 생겨 흡음효과가 향상되고, 체결부재(7)에 의해 체결되므로 착탈이 용이하게 되는 효과가 있다.The present invention has the effect that the interval is generated by the thickness of the spacer 6, the sound absorption effect is improved, and is fastened by the fastening member 7 so that the attachment and detachment is easy.
이상에서 살펴본 바와 같이, 본 고안은 흡읍재 및 브래킷 사이에 스페이서가 위치되고, 체결부재에 의해 흡음재가 브래킷에 취부되어, 흡음효과가 상승되고, 흡음재의 착탈이 용이하도록 하는 매우 유용한 것이다.As described above, the present invention is a very useful for the spacer is located between the suction member and the bracket, the sound absorbing material is attached to the bracket by the fastening member, the sound absorbing effect is increased, and the sound absorbing material can be easily attached and detached.
