At one end of the cylinder block 30 to which the front plate 32 is coupled, a cylindrical flange 34 for tightening the vibration-proof soundproof cover 12 from the cylinder block 30 by a predetermined distance to increase the transmission distance of the noise is fastened to the screw 18. Combined by). Sealing members 36 are inserted in the left and right sides of the flange 34. On the left side of the flange 34, a dustproof soundproof cover 12 is coupled by a fastening screw 18. As shown in FIG. The dustproof soundproof cover 12 is joined to a sintered rubber, which is the dustproof member 20, spaced apart from the dustproof soundproof cover 12 by a predetermined interval in order to prevent itself from vibrating by the vibrating member.
이러한 구성을 갖는 방진방음덮개(12)는 소음 및 진동 부재(10)와 일정간격 이격하여 결합되어 공기층을 형성하여 소음 및 진동 부재(10)에서 발생하는 소음을 완충하여 주고, 또한 부재(10)와 방진방음덮개(12) 사이에 방진부재(20)를 삽입하여 진동을 줄여주거나, 그 자신의 일부분을 일정 간격 이격하여 방진부재(20)로 결합하여 진동을 줄여주고 있다.The dustproof soundproof cover 12 having such a configuration is coupled to the noise and vibration member 10 at regular intervals to form an air layer to cushion the noise generated from the noise and the vibration member 10, and also the member 10. Insert the dustproof member 20 between the dustproof and soundproof cover 12 to reduce the vibration, or to reduce the vibration by combining a portion of its own with a dustproof member 20 at regular intervals.
하지만, 방진재를 삽입하여 부재의 진동을 줄여주는 것에는 그 한계가 있으며, 또한 공기층의 완충작용으로 인해 소음이나 진동을 줄여주는 것도 한계가 있다. 따라서, 본 고안은 이러한 문제점을 해결하기 위해 소음 및 진동발생 부재에 결합되는 방진방음덮개를 부재의 형상에 비대칭적으로 형성하여 소음으로 발생하는 공명을 줄이고 방진방음덮개의 강성을 높이며, 방진방음덮개 내부에 흡음재를 접합하여 부재에서 발생하는 소음을 흡음하는 것과 부재의 노드점 사이에 방진재를 삽입하여 부재의 진동을 흡수하고 방진방음덮개와 부재의 체결부분에 방진재를 삽입하여 체결함으로써 방진방음덮개의 진동을 개선한 방진방음부분덮개를 제공함에 있다.However, there is a limit to reducing the vibration of the member by inserting the vibration damper, and also has a limit to reduce the noise or vibration due to the buffering action of the air layer.

이와 같은 목적을 달성하기 위한 본 고안의 특징은 소음 및 진동이 발생되는 부재에 체결되는 방진방음덮개에 있어서,A feature of the present invention for achieving the above object is a dustproof soundproof cover which is fastened to a member that generates noise and vibration,
상기 부재의 형상에 비대칭적으로 체결되어 방진 방음할 수 있도록 내면에 흡음재를 구성하고, 상기 흡음재와 상기 부재 사이에 삽입되는 방진부재를 포함하는 방진방음부분덮개에 있다.The soundproof material is configured on the inner surface so as to be asymmetrically fastened to the shape of the member so as to be dustproof, and a dustproof soundproof part cover including a dustproof member inserted between the sound absorber and the member.
이하, 참조된 도면에 의거 본 고안에 따른 바람직한 실시예를 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 3a는 본 고안에 따른 방진방음부분덮개를 나타낸 평면도이고, 도 3b는 도 3a의 A-A선을 잘라내어 나타낸 선단면도이다. 도시한 바와 같이, 소음 및 진동이 발생되는 부재(10)의 외면에는 일정간격 이격되도록 방진방음덮개(12)가 체결나사들(18)에 의해 결합되어 있다. 부재(10)에 체결된 방진방음덮개(12)와 방진방음덮개(12)와 체결나사(18) 사이에는 방진부재로서 방진고무(22)가 삽입되어 있다. 그리고, 방진방음덮개(12)의 내면에는 흡음재(24)가 접합되어 있다. 또한, 흡음재(24)와 부재(10) 사이의 일부분에는 방진부재(20)가 다수 개 삽입되어 있다.Figure 3a is a plan view showing a dustproof soundproof cover according to the present invention, Figure 3b is a cross-sectional view taken cut line A-A of Figure 3a. As shown, the dustproof soundproof cover 12 is coupled to the outer surface of the member 10 where the noise and vibration are generated by fastening screws 18 so as to be spaced at a predetermined interval. Between the dustproof soundproof cover 12 fastened to the member 10, the dustproof soundproof cover 12, and the fastening screw 18, the dustproof rubber 22 is inserted as a dustproof member. The sound absorbing material 24 is bonded to the inner surface of the dustproof soundproof cover 12. In addition, a plurality of dustproof members 20 are inserted in a portion between the sound absorbing material 24 and the member 10.
도 4는 본 고안에 따른 또다른 실시예로서 오일팬에 적용된 예를 나타내고 있다. 도시한 바와 같이, 실린더블록(11)에는 일정 간격 이격하여 일정한 형상을 가진 오일팬의 외부판(40)이 체결나사(18)에 의해 결합되어 있다. 이 체결나사(18)에는 방진부재(10)로서 방진고무(22)가 삽입되어 실린더블록(11)과 외부판(40) 사이의 진동을 차폐하고 있다. 또한, 체결나사(18)에는 외부판(40)에 비대칭적인 형상을 갖는 방진방음덮개(12)가 결합되어 있다. 이 방진방음덮개(12)와 외부판(40)이 결합된 체결나사(18)에는 외부판(40)과 방진방음덮개(12) 사이에 방진고무(22)가 삽입되어 있다. 또한, 체결나사(18)의 머리부분과 방진방음덮개(12) 사이에도 방진고무(22)가 삽입되어 있다.Figure 4 shows an example applied to the oil pan as another embodiment according to the present invention. As illustrated, the outer plate 40 of the oil pan having a predetermined shape is spaced apart from the cylinder block 11 by a fastening screw 18. The fastening screw 18 is inserted with the anti-vibration rubber 22 as the anti-vibration member 10 to shield the vibration between the cylinder block 11 and the outer plate 40. In addition, the fastening screw 18 is coupled to the anti-vibration soundproof cover 12 having an asymmetrical shape to the outer plate (40). The dustproof rubber 22 is inserted between the outer plate 40 and the vibrationproof soundproof cover 12 in the fastening screw 18 to which the dustproof soundproof cover 12 and the outer plate 40 are coupled. In addition, the anti-vibration rubber 22 is inserted between the head of the fastening screw 18 and the anti-vibration soundproof cover 12.
그리고, 방진방음덮개(12)의 내부에는 흡음재(24)가 굴곡된 면을 따라 접합되어 있다. 이 방진방음덮개(12)는 또한 일정간격 이격되도록 분리되어 있다. 이 방진방음덮개(12)의 분리된 부분에는 방진부재인 소결고무(20)로 접합되어 분리된 부분을 결합하고 있다. 또한, 방진방음덮개(12)와 외부판(40) 사이에는 외부판(40)의 진동노드점들에 방진재들(20)이 삽입되어 있다.The sound absorbing material 24 is joined to the inside of the dustproof soundproof cover 12 along the curved surface. The dustproof soundproof cover 12 is also separated to be spaced apart at regular intervals. The separated part of the dustproof soundproof cover 12 is joined to the separated part by bonding with the sintered rubber 20 which is a dustproof member. In addition, the vibration isolator 20 is inserted into the vibration node points of the outer plate 40 between the anti-vibration soundproofing cover 12 and the outer plate 40.
이러한, 구성을 갖는 방진방음부분덮개(12)는 실린더블록(11)에 의한 외부판(40)의 진동을 방진고무(22)에 의해 일부 진동을 흡수하고, 외부판(40)의 진동을 방진방음덮개(12)와 외부판(40) 사이에 삽입된 방진재들(20)에 의해 방진방음덮개(12)의 강성을 증가시킴으로써 억제시킨다. 그리고, 외부판(40)에서 발생되는 소음은 방진방음덮개(12)의 흡음재(24)에 의해 차폐된다. 또한, 방진방음덮개(12)가 외부판(40)에 대해 비대칭이므로 소음으로 인한 공명현상을 방지한다.The dustproof soundproof part cover 12 having such a configuration absorbs vibrations of the outer plate 40 by the cylinder block 11 by the anti-vibration rubber 22, and vibrations of the outer plate 40. It is suppressed by increasing the stiffness of the dustproof soundproof cover 12 by the dustproof materials 20 inserted between the soundproof cover 12 and the outer plate 40. In addition, the noise generated by the outer plate 40 is shielded by the sound absorbing material 24 of the dustproof soundproof cover 12. In addition, the dustproof soundproof cover 12 is asymmetrical with respect to the outer plate 40, thereby preventing resonance due to noise.
따라서, 본 고안에 따른 방진방음부분덮개는 체결나사에 결합된 방진고무에 의해 진동을 흡수할 뿐만 아니라, 외부판과 방진방음덮개 사이의 방진재에 의해서도 진동이 흡수되므로 진동흡수의 이중효과를 가져오고, 방진방음재의 내면에 접합된 흡음재에 의해 소음을 차폐하는 효과를 갖게 된다. 또한, 방진방음재의 형상이 대상부재에 대해 비대칭적이므로 소음에 기인한 공명현상을 방지하여주는 효과를 갖는다.Therefore, the vibration-proof soundproof part cover according to the present invention not only absorbs the vibration by the anti-vibration rubber coupled to the fastening screw, but also the vibration is absorbed by the anti-vibration material between the outer plate and the anti-vibration soundproof cover, thereby bringing the dual effect of vibration absorption. The sound-absorbing material bonded to the inner surface of the vibration-proof soundproofing material has the effect of shielding noise. In addition, since the shape of the anti-vibration soundproof material is asymmetrical to the target member, it has an effect of preventing resonance caused by noise.
본 고안의 목적은 소음 및 진동이 발생되는 부재의 부위중 특히 소음 및 진동이 심하게 발생하는 부분에 부재의 소음 및 진동을 차폐하는 방진방음부분덮개를 제공함에 있다.It is an object of the present invention to provide a dustproof soundproof cover which shields the noise and vibration of a member, particularly in a portion where the noise and vibration are severely generated.
