Description

자동차용 고온고압 호스의 소음저감장치{Noise reducing apparatus for vehicle hose}Noise reduction apparatus for high temperature high pressure hose for automobiles

본 발명은 자동차용 고온고압 호스에 관한 것으로, 특히 고온과 고온에 의해 팽창하는 것을 방지하여 유체의 흐름에 따른 소음을 저감시키는 자동차용 고온고압 호스의 소음저감장치에 관한 것이다.
The present invention relates to a high temperature and high pressure hose for automobiles, and more particularly, to a noise reduction device for a high temperature and high pressure hose for automobiles to prevent the expansion due to the high temperature and high temperature to reduce the noise caused by the flow of the fluid.

일반적으로 자동차의 동력발생계통인 엔진에서 고온고압용 공기를 전달하는데 사용하는 호스는 여러 가지 종류가 있으며, 이러한 호스가 갖추어야 할 조건의 일예로서 자동차 엔진의 배기 매뉴폴더에 장착된 호스는 800℃ 이상의 고온의 연료 및 공기가 통과하게 되므로 고온을 견딜 수 있도록 내구성을 지녀야 한다.In general, there are many types of hoses used to deliver high temperature and high pressure air in an engine, which is a power generation system of a vehicle. Hot fuel and air will pass through, so it must be durable to withstand high temperatures.

도1은 이러한 고온 및 고압 상태의 유체를 전달하기 위한 호스(100)의 구조를 보인 도로서, 좁은 공간으로 이루어진 자동차의 엔진룸의 배치상태를 간결하게 하기 위해 고무호스는 엔진룸의 구조 상태에 따라 3차원으로 복잡하게 굴곡 성형된다.1 is a view showing the structure of a hose 100 for delivering a fluid of such a high temperature and high pressure state, in order to simplify the arrangement state of the engine room of a car made of a narrow space, the rubber hose is in the structural state of the engine room Therefore, it is complexly bent in three dimensions.

그런데, 고온 및 고압을 갖는 유체가 호스(100)의 내부를 통과하게 되면 호스(100)가 고온 및 고압에 의해 팽창하게 되고, 이때 빠른 속도로 흐르는 유체가 팽창에 의해 면적이 커진 골곡부위(110)와 접촉하면, 굴곡부위(110)의 접촉면적이 넓어져 있으므로 소음이 크게 증가한다.However, when the fluid having a high temperature and high pressure passes through the inside of the hose 100, the hose 100 is expanded by the high temperature and the high pressure, and at this time, the fluid flowing at a high speed is enlarged in area due to expansion of the curved portion 110. ), Since the contact area of the bent portion 110 is widened, the noise is greatly increased.

도3(a)는 이러한 종래의 호스(100)에서 발생하는 소음의 크기를 측정한 자료로서, 고속의 유체가 굴곡부위(110)에 접촉하여 70dB 이상을 갖는 큰 소음이 발생한 상태를 보여주는 것이다.Figure 3 (a) is a data measuring the size of the noise generated in the conventional hose 100, showing a state in which the high-speed fluid has a large noise having 70dB or more in contact with the bent portion (110).

이로인해, 운전자 및 탑승자에게 불쾌한 소음을 주게 되어 안락한 승차를 방해하는 큰 요인이 된다.
This causes unpleasant noise to the driver and the occupant, which is a major factor in preventing comfortable riding.

본 발명은 이러한 종래의 문제점을 해결하기 위하여, 호스의 외측에 철사를 스파이럴 형태로 감아 고온 및 고압에 의해 호스가 팽창되는 것을 방지함으로써 소음을 저감시키도록 하는 자동차용 고온고압 호스의 소음저감장치에 관한 것이다.
The present invention is to solve the conventional problems, to reduce the noise by reducing the noise by winding the wire in the spiral form on the outside of the hose to prevent the hose from expanding by high temperature and high pressure It is about.

상기의 목적을 달성하기 위한 본 발명의 자동차용 고온고압 호스의 소음저감장치는,Noise reduction device for a high temperature and high pressure hose for automobiles of the present invention for achieving the above object,

자동차의 엔진룸에 장착되어 고온고압의 유체를 전달하며, 엔진룸의 구조 상태에 따라 직선부위와 굴곡부위를 갖는 자동차의 고온고압 호스에 있어서,In the high temperature and high pressure hose of the vehicle is mounted in the engine room of the vehicle to transfer the fluid of high temperature and high pressure, and has a straight portion and a bent portion according to the structural state of the engine room,

상기 호스의 외측면에 철사가 스파이럴 형태로 권취되어 고온고압의 유체에 의해 호스의 팽창이 방지되도록 구성된 것을 특징으로 한다.
Wire is wound on the outer surface of the hose in the form of a spiral, characterized in that configured to prevent expansion of the hose by the fluid of high temperature and high pressure.

이러한 구조를 갖는 본 발명은 고온고압 호스의 외측에 철사를 스파이럴 형태로 권취하여 고온고압의 유체에 의한 팽창을 방지함으로써 고속으로 흐르는 유체와의 접촉면적을 그대로 유지시킴으로써 소음을 저감시켜 탑승자에게 안락한 승차감을 제공하는 효과를 갖는다.
The present invention having such a structure wound the wire in the form of a spiral on the outside of the high temperature and high pressure hose to prevent expansion by the high temperature and high pressure fluid to maintain the contact area with the fluid flowing at high speed as it is to reduce the noise to ride comfort comfortable to the occupant Has the effect of providing.

이와같이 구성된 본 발명을 첨부한 도면을 참조하여 상세히 설명한다.The present invention configured as described above will be described in detail with reference to the accompanying drawings.

본 발명의 호스(200) 구조는 종래의 호스(100)와 동일하거나 유사하며, 호스(200)의 외측으로는 철사(300)가 일측 끝부위부터 타측 끝부위까지 스파이럴 형태로 권취되어 있다.The structure of the hose 200 of the present invention is the same as or similar to the conventional hose 100, the wire 300 is wound in a spiral form from one end to the other end of the outside of the hose 200.

즉, 호스(200)의 양끝부위를 엔진의 다른 계통에 연결하기 위한 밴드가 장착되므로, 그 밴드가 장착되는 위치를 제외한 부위까지 철사(300)가 스파이럴 형태롤 권취되는 것이다.That is, since the band for mounting both ends of the hose 200 to the other system of the engine is mounted, the wire 300 is wound in a spiral form to the portion except the position where the band is mounted.

이러한 철사(300)는 호스(200)의 직선부위(220)에서는 비교적 등간격을 형성하면서 권취되고, 굴곡부위(210)에서는 그 간격이 조밀하게 형성함이 바람직한데, 그 이유는 고온고압의 유체에 의해 굴곡부위(210)에서 팽창이 더 크게 발생하므로 그 위치에서 철사(300)가 조밀하게 권취되도록 함으로써 팽창력에 대해 버팀력을 크게 가지도록 한다.The wire 300 is wound while forming a relatively equal interval at the straight portion 220 of the hose 200, the gap is preferably formed densely at the bent portion 210, because the fluid of high temperature and high pressure Since the expansion occurs in the bent portion 210 by a larger so that the wire 300 is tightly wound at the position to have a greater force against the expansion force.

철사(300)는 호스(200)의 외측면서 밀착되면서 권취되어 호스(300)의 팽창을 억지하게 된다. The wire 300 is wound while being in close contact with the outside of the hose 200 to inhibit the expansion of the hose 300.

한편, 상기 스파이럴 형태로 권취되는 철사(300)의 양측 끝부위에는 고리와 걸이 구조에 의해 마감되어 권취된 철사가 풀리는 것을 방지하는데, 이를 위해서 철사(300)의 끝부위가 꼬임에 의해 원형의 고리부(310)가 형성되며, 철사(300)의 단부에는 후크 형태의 걸이부(320)가 형성된다.On the other hand, both ends of the spiral wound wire 300 is closed by a hook and hook structure to prevent the wire is unwinding, for this purpose the end of the wire 300 is twisted by a circular ring The part 310 is formed, and a hook portion 320 in the form of a hook is formed at the end of the wire 300.

따라서, 상기 고리부(310)부터 철사(300)가 호스(200)의 외측을 1회전 또는 그 이상 권취하여 고리부(310)에 걸이부(320)가 걸리게 된다.Therefore, the hook part 310 is caught by the hook part 310 by winding the outer side of the hose 200 one or more times from the hook part 310.

그러므로, 호스(200)가 고온고압의 유체에 의해 팽창력이 가해지더라도 철사(300)가 밀착되어 팽창을 억지하며, 또한 고리부(310)와 걸이부(320)의 체결에 의해 억지력이 유지되면서 철사(300)의 풀림이 방지된다.
Therefore, even if the hose 200 is applied to the expansion force by the fluid of the high temperature and high pressure, the wire 300 is in close contact to inhibit expansion, and also the wire while maintaining the deterrent force by the engagement of the hook portion 310 and the hook portion 320 Loosening of 300 is prevented.

도3(b)는 본 발명에 의해 소음이 저감된 상태를 보여주는 자료로서, 도3(a)에서와 같은 종래의 소음영역과 동일한 위치에서 70dB 이상의 소음이 현저히 저감된 상태를 보여준다.
Figure 3 (b) is a data showing a state in which the noise is reduced by the present invention, showing a state in which the noise of 70dB or more is significantly reduced at the same position as the conventional noise region as in Figure 3 (a).
