본 발명은 자동차 엔진의 흡기매니홀드에 있어서, 엔진으로부터 시작되는 진동의 전달을 막기 위한 것으로 체결구조를 개선한데 특징이 있는 것이다.The present invention is characterized in that the fastening structure is improved in the intake manifold of an automobile engine to prevent transmission of vibrations starting from the engine.

일반적으로 자동차 엔진의 흡기매니홀드는 엔진의 헤드부에 고정되어 공기를 될 수 있는 한 저항을 적게 받으면서 실린더로 유도하는 관이며, 각 실린더에 균일한 양의 공기를 분배하게 된다.In general, the intake manifold of an automobile engine is a tube which is fixed to the head of the engine and guides the cylinder with less resistance as much as possible to the air, and distributes a uniform amount of air to each cylinder.

이러한 종래의 흡기매니홀드는 대부분 제3도 도면에서 보는 바와 같이 엔진의 헤드부(a)와 흡기매니홀드(b)의 사이에 가스켓(c)을 개입시킨 상태에서 통상의 보울트(d)로 조여주는 것인바, 별도의 진동방지 구조를 가지지 못하는 것이기 때문에 엔진 구동시 발생하는 진동은 가진원에서 전파되어 각 구조물로 전파되고, 전파되면서 떨림에 의한 증폭이 발생하는 것이다.Most of the conventional intake manifolds are tightened with a conventional bolt (d) in a state where a gasket (c) is interposed between the head (a) and the intake manifold (b) of the engine as shown in FIG. Since it does not have a separate anti-vibration structure, the vibration generated when the engine is driven is propagated in the excitation source and propagated to each structure, and the amplification by the vibration is generated as it propagates.

그리고 고무부재를 진동부분에 개입시켜 방진구로 사용하는 통상의 경우 체결을 위한 압착력이 적당히 조절된 상태를 유지하지 않으면 고무부재가 너무 눌려 점차 파손되어 지고, 또 경화되고, 수축 및 이완이 일어나는 물성변화가 있기 때문에 자동차의 주요부분에는 이용을 하지 못하고 있는 실정이다.And in the case of using the rubber member as a dustproof hole through the vibration part, if the pressing force for fastening is not maintained in a properly controlled state, the rubber member is pressed too much and is gradually damaged, further hardening and shrinking and relaxation occur. Because there is a major part of the car is not available.

따라서 본 발명은 상기와 같은 제반 문제점을 감안해 이를 시정보완하고자 안출한 것으로서 발명의 주된 목적은 고무가스켓을 사용하여 진동의 진원지부분에서 근본적으로 차단하여 소음을 감소시키고자 하는데 있으며, 특히 진동방지용 고무가스켓의 물성변화에 대처할 수 있도록 하는데 있는 것이다.Therefore, the present invention has been made to solve the problem in view of the above-mentioned problems, the main object of the invention is to reduce the noise by fundamentally blocking at the epicenter of the vibration using a rubber gasket, in particular a rubber gasket for vibration prevention It is to be able to cope with changes in physical properties.

그리고 이를 위한 특징적인 구성은 실린더헤드의 위에 부착 고정하는 흡기매니홀드의 사이에 고무가스켓을 개입시키고, 위로부터 보울트를 체결하고 고정하되, 실린더헤드에 형성한 암나사는 그 깊이를 한정하면서 구멍바닥을 수평으로 가공하고, 여기에 체결된 보울트의 끝단 역시 수평으로 가공하며, 그 보울트머리의 아래에 압축스프링을 끼운 후, 이 압축스프링이 흡기매니홀드의 안장부위에 얹히는 스프링받침구위에 받쳐지도록 구성하므로써 고무가스켓으로서 진동 소음을 예방하되 보울트에 끼운 압축스프링의 탄성이 고무가스켓의 물성변화를 방지하고 스프링받침구에 의해 압축스프링의 흔들림 및 탄성력 저하에 의한 내구성 저하를 방지하게 된다.And a characteristic configuration for this is through the rubber gasket between the intake manifold attached to and fixed on the cylinder head, and fastening and fixing the bolt from above, the female thread formed in the cylinder head is limited to the depth of the hole Machined horizontally, the ends of the bolts fastened to it are also machined horizontally, and the compression springs are fitted under the heads of the bolts, so that the compression springs are supported by the spring support which is placed on the saddle of the intake manifold. Thus, the rubber gasket prevents vibration noise, but the elasticity of the compression spring inserted into the bolt prevents the change of the physical properties of the rubber gasket and the durability of the compression spring by the spring support to prevent the degradation of durability.

이하 본 발명의 상세한 구성 및 작용효과를 첨부한 도면에 따라 설명하면 다음과 같다.Hereinafter, the detailed configuration and effect of the present invention will be described with reference to the accompanying drawings.

제1도는 본 발명의 체결상태를 보인 단면도이고, 제2도는 본 발명의 구성을 상세히 보이기 위한 분해상태의 단면도이다.1 is a cross-sectional view showing a fastening state of the present invention, Figure 2 is a cross-sectional view of the disassembled state for showing the configuration of the present invention in detail.

제2도 도면에서 보듯이 엔진의 실린더헤드(1)위에 흡기매니홀드(2)를 결합하되, 그 사이에는 고무로 제작된 고무가스켓(3)을 개입시킨다.As shown in FIG. 2, the intake manifold 2 is coupled to the cylinder head 1 of the engine, while the rubber gasket 3 made of rubber is interposed therebetween.

이때 중요한 점은 보울트(4)가 나삽될 실린더헤드(1)의 암나사(11)는 임의의 깊이(L)를 한정하고, 그 구멍바닥면(12)을 수평으로 형성하며, 또 상기한 보울트(4)의 끝단(41)도 수평면으로 형성하여 이들을 결합하였을 때 서로 맞닿아 더 이상 조여지지 않도록 한다.At this time, the important point is that the female screw 11 of the cylinder head 1 to which the bolt 4 is to be threaded defines an arbitrary depth L, and forms the hole bottom surface 12 horizontally. The end 41 of 4) is also formed in a horizontal plane so that when they are joined to each other, they are no longer tightened.

흡기매니홀드(2)의 보울트삽입공(22) 입구에는 그 보다 큰 직경의 안장부(21)를 형성하여 스프링받침구(5)가 얹힐 수 있도록 하며, 상기한 보울트의 머리(42)아래에 끼운 압축스프링(6)이 이 스프링받침구(5)의 사이에서 적당한 탄성으로 받쳐지도록 한다.At the inlet of the bolt insertion hole 22 of the intake manifold 2, a saddle 21 having a larger diameter is formed so that the spring support 5 can be placed thereon, under the head 42 of the bolt. The fitted compression spring 6 is supported by a suitable elasticity between the spring support (5).

상기한 스프링받침구(5)는 상기 연장부(22)의 내경에 끼워 지지되는 소경부(5a)와, 그 소경부(5a)로부터 확개되어 흡기매니홀드(2)의 외표면에 노출되는 대경부(5b)로 구성되고, 소경부(5a)와 대경부(5b)는 수평의 스프링지지부(5c)로 연결되어 있다. 그리고 상기 압축스프링(6)은 대경부(5b)에 끼워져 스프링지지부(5c)에 의해 지지되어지게 된다.The spring support 5 is extended from the small diameter portion 5a and the small diameter portion 5a, which is supported by the inner diameter of the extension portion 22, and is exposed to the outer surface of the intake manifold 2. It consists of the neck part 5b, and the small diameter part 5a and the large diameter part 5b are connected by the horizontal spring support part 5c. The compression spring 6 is fitted to the large diameter portion 5b to be supported by the spring support portion 5c.

상기와 같이 구성된 본 발명은 제1도 도면에서 보는 바와 같이 실린더헤드(1)의 위로 고무가스켓(3)을 얹은 후, 그위에 다시 흡기매니홀드(2)를 얹어 준다.According to the present invention configured as described above, the rubber gasket 3 is placed on the cylinder head 1 as shown in FIG. 1, and then the intake manifold 2 is placed thereon.

보울트(4)를 조여 줄 때에는 압축스프링(6)을 먼저 끼운후, 흡기매니홀드(2)의 안장부(21)에 스프링받침구(5)를 얹고, 보울트(4)가 더 이상 들어가지 않을 때까지 조여 준다.When tightening the bolt 4, the compression spring 6 is inserted first, and then the spring support 5 is placed on the saddle 21 of the intake manifold 2 and the bolt 4 is no longer inserted. Tighten until

이와 같이 하면 조립이 완료되는데 이때 고무가스켓(3)은 엔진의 진동이 흡기매니홀드(2)로 전달되지 않도록 하는 역할을 하는 것이고, 또 보울트(4)는 흡기매니홀드(2)를 실린더헤드(1)에 고정시키되, 그 끝단(41)이 암나사(11)의 구멍바닥(12)에 닿도록 조여주면 암나사(11)의 깊이(L)만큼만 나삽되어 머리(42) 아래에 끼운 압축스프링(6)의 힘으로 체결상태를 유지하도록 한다.In this way, the assembly is completed. At this time, the rubber gasket (3) serves to prevent the vibration of the engine from being transmitted to the intake manifold (2), and the bolt (4) moves the intake manifold (2) to the cylinder head ( 1), but the end 41 is tightened so as to contact the bottom of the hole 12 of the female screw 11, the compression spring (6) is screwed only by the depth (L) of the female screw 11 and inserted under the head 42 (6) Keep the tightening state with the force of).

압축스프링(6)의 체결력은 압축스프링(6)의 탄성계수와 암나사(11)의 깊이(L)와 보울트(4)의 길이에 의해 사전에 계획되는 것이며, 이와 같이 하는 것은 상기한 고무가스켓(3)의 물성변화 즉, 장시간 경과 하므로서 경화되고, 수축 및 이완되며, 탄성이 약해지는 성질변화를 가능한 없애기 위한 것인데 결론적으로 고무가스켓(3)의 탄성이 가장 양호한 상태가 지속되도록 하면서 그 수명을 연장시키기 위한 것이다.The clamping force of the compression spring 6 is planned in advance by the elastic modulus of the compression spring 6, the depth L of the female thread 11, and the length of the bolt 4, and the above-mentioned rubber gasket ( This is to eliminate the change in physical properties of 3), that is, harden, shrink and relax as it elapses for a long time and weaken elasticity. In conclusion, the elasticity of the rubber gasket (3) is maintained in the best elastic state and its life is extended. It is to let.

그리고 스프링(6)이 스프링받침구(5)에 의해 강제 지지되어지므로써 보울트(4)의 축심과 안정적인 동축을 유지할 수 있게 되는데, 상기 스프링받침구(5)의 소경부(5a)는 안장부(21)에 삽입된 상태에서 압축스프링(6)의 탄발력을 받고 있게 되어 스프링받침구(5) 자체는 안장부(21)에 안정되게 설치된 상태가 유지되는 것이며, 또한 압축스프링(6)의 하단부는 스프링받침구(5)의 지지부(5c)에 안착된 상태에서 대경부(5b)에 의해 구속된 상태이므로 압축스프링(6)의 하단부가 이탈되는 사례가 방치된다. 따라서, 엔진의 진동이 크게 발생하더라도 압축스프링(6)의 위치 이탈이 방지되어 스프링 손상 및 탄성력 저하가 방지되어지게 된다.And because the spring (6) is forcibly supported by the spring support (5) it is possible to maintain a stable coaxial with the shaft center of the bolt (4), the small diameter portion (5a) of the spring support (5) is the saddle Receiving the elastic force of the compression spring (6) in the state inserted into the (21) is the spring support (5) itself is maintained in a state that is stably installed in the saddle (21), and also of the compression spring (6) Since the lower end is restrained by the large diameter part 5b in a state seated on the support part 5c of the spring support 5, the case in which the lower end of the compression spring 6 is released is left. Therefore, even if the vibration of the engine is large, the deviation of the position of the compression spring 6 is prevented to prevent the spring damage and elastic force degradation.

위에서 상세히 설명한 바와 같은 본 발명은 엔진의 실린더헤드(1)와 흡기매니홀드(2)의 사이에 고무재질로 만든 고무가스켓(3)을 사용하였기 때문에 진동과 그에 따른 소음발생을 예방하게 된 것이며, 특히 이들을 체결하는 보울트(4)의 길이, 암나사(11)의 깊이(L), 압축스프링(6)의 탄성을 모두 감안하여 항상 적당한 힘으로 체결되어 있도록 하고 또한 스프링받침구(5)에 의해 지지되도록 하였기 때문에 고무가스켓(3)의 수명 및 스프링(6)의 수명이 장기화되는 것이고, 따라서 엔진 등 주요부에서 고무가스켓을 방지수단으로 사용할 수 있는 것이다.The present invention as described in detail above, because the rubber gasket (3) made of a rubber material between the cylinder head (1) and the intake manifold (2) of the engine is to prevent the vibration and the resulting noise, In particular, in consideration of the length of the bolt (4) for fastening them, the depth (L) of the female screw (11), and the elasticity of the compression spring (6), they are always fastened with a suitable force and supported by the spring support (5). Since the life of the rubber gasket 3 and the life of the spring 6 is prolonged, it is possible to use the rubber gasket as a preventive means in the main part such as the engine.
