Description
본 발명은 차량용 에어클리너에 관한 것으로, 더욱 상세하게는 엔진쪽으로 흡입되는 공기의 유동성 향상으로 차량의 동력성능을 향상시키면서 액화천연가스(LPG)차량에 경우 연소실의 역화에 의한 자체 파손을 방지할 수 있는 차량용 에어클리너에 관한 것이다.The present invention relates to a vehicle air cleaner, and more particularly, to improve the power performance of the vehicle by improving the fluidity of the air sucked into the engine, and to prevent the self-damage caused by backfire of the combustion chamber in the case of LPG vehicles. The present invention relates to a vehicle air cleaner.
주지된 바와 같이 차량용 에어클리너는 외기의 흡입공기를 필터부에서 여과한 다음, 엔진의 흡기 다기관쪽으로 정화된 공기를 공급하는 역할을 수행하는 바, 이와 같은 역할을 수행하는 종래 에어클리너의 설치구조를 도 3을 참고로 살펴보면, 외부공기가 흡입되는 덕트(101)에 에어클리너의 하부커버(103b)가 연결되고 이 하부커버(103b)의 상부쪽에 장착된 상부커버(103a)에는 엔진측 공기호스(102)가 연결되어 있으며, 상기 상하부커버(103a,103b)의 내부에는 공기를 여과하는 필터(104)가 내장되어 있다.As is well known, the vehicle air cleaner performs a role of supplying purified air to the intake manifold of the engine after filtering the intake air of the outside air from the filter part. Referring to FIG. 3, the lower cover 103b of the air cleaner is connected to the duct 101 through which the outside air is sucked, and the engine side air hose is attached to the upper cover 103a mounted on the upper side of the lower cover 103b. 102 is connected, and a filter 104 for filtering air is built into the upper and lower covers 103a and 103b.
종래 이러한 에어클리너는 필터(104)의 면적에 비해 여과효율이 떨어져서 공기의 정화효율이 저하될 뿐만 아니라, 공기가 흡입되는 덕트(101)와 여과된 공기가 빠져나가는 엔진측 공기호스(102)의 방향이 불일치하여 공기 통기저항이 높아서 엔진의 동력성능이 저하되는 단점을 지니고 있었다.Conventionally, such an air cleaner has a lower filtration efficiency than the area of the filter 104, thereby lowering the purification efficiency of the air, as well as the duct 101 through which the air is sucked and the engine side air hose 102 through which the filtered air exits. Due to the mismatch in direction, the air vent resistance was high, which lowered the engine's power performance.
더욱이 상기 덕트(101)와 에어클리너 자체가 합성수지로 제작되어 있기 때문에 차량 소음 및 진동 저감 성능을 개선시키기 위해 흡기계통에 별도의 공명기를 설치하는 번거로움도 있었다.In addition, since the duct 101 and the air cleaner itself are made of synthetic resin, there was also the inconvenience of installing a separate resonator in the intake cylinder to improve vehicle noise and vibration reduction performance.
이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 에어클리너 전체 형상을 유선형으로 형성시키어 통기저항을 감소시키면서 필터의 여과면적 증대로 여과 효율의 향상과 소음 및 진동저감 성능이 향상될 뿐만 아니라, 액화천연가스 차량에 있어서 역화시 에어클리너 자체의 파손을 방지하는 차량용 에어클리너를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the conventional problems as described above, by increasing the filtration area of the filter while reducing the airflow resistance by forming the overall shape of the air cleaner to improve the filtration efficiency and noise and vibration reduction performance is improved. In addition, the object of the present invention is to provide a vehicle air cleaner which prevents damage of the air cleaner itself when backfired in a LNG gas vehicle.

상기와 같은 목적을 달성하기 위한 본 발명은 덕트와 호스에 각각 연결되는 병모양의 유선형 전후커버의 내부에 원통형 필터부가 내장되되, 이 원통형 필터부의 전면쪽에는 유선형 원뿔의 고무밀봉부가 스크류 방식으로 체결되고 이의 후면쪽에는 고무 원형 밀봉부를 매개로 후커버의 스크류 방식으로 체결되어 이루어진 구조로 되어 있다.The present invention for achieving the above object is a cylindrical filter portion is built in the inside of the bottle-shaped streamline front and rear cover connected to each of the duct and the hose, the rubber seal of the streamlined cone is fastened in a screw manner to the front side of the cylindrical filter portion And the rear side thereof has a structure made by fastening with a screw method of the rear cover via a rubber circular seal.
이하 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 차량용 에어클리너의 전체 분리 사시도이고, 도 2는 도 1의 결합단면도로서 공기의 흐름이 도시되어 있다.1 is a perspective view of the entire separation of the vehicle air cleaner according to the present invention, Figure 2 is a cross-sectional view of the air flow shown in FIG.
본 발명은 외부공기가 흡입되는 덕트(1)와 엔진쪽으로 정화된 공기를 보내는 호스(2)에 각각 커버들(3a,3b)이 연결되고 이 커버들(3a,3b)내부에는 필터부(4)가 내장되어 이루어진 차량용 에어클리너에 있어서, 상기 필터부(4)가 내장 설치되는 병모양의 유선형 전후커버(3a,3b)에 각각 연결되는 덕트(1)와 호스(2)는 동축선상으로 배치되고 이 원통형 필터부(4)의 전면쪽에는 유선형 원뿔의 고무밀봉부(6)가 스크류 방식으로 체결되며 이의 후면쪽에는 고무환형 밀봉부(7)를 매개로 스크류 방식으로 후커버(3b)와 체결되어 이루어진 구조로 되어 있다.According to the present invention, the covers 3a and 3b are connected to the duct 1 through which the outside air is sucked and the hose 2 which sends the purified air to the engine, and the filter part 4 is disposed inside the covers 3a and 3b. In the vehicle air cleaner having a built-in), the duct (1) and the hose (2) connected to the streamlined front and back cover (3a, 3b) is installed coaxially, respectively, the filter unit 4 is built-in On the front side of the cylindrical filter portion 4, the rubber sealing portion 6 of the streamlined cone is fastened by a screw method, and on the rear side thereof, the rear cover 3b and the rubber type sealing portion 7 are screwed through the screw method. It is structured by being fastened.
그리고 상기 전커버(3a)는 와이어 골격부(8)에 면사직조물(9)이 부착되어 코팅처리 되어 있다.And the front cover (3a) is a cotton yarn woven fabric (9) is attached to the wire skeleton portion 8 is coated.
또한 상기 전후커버(3a,3b)의 연결부위는 연결 플랜지 부위에 클립(10)이 체결되고, 상기 전커버(3a)의 입구쪽은 외부공기 유입구인 덕트(1)와 연결되며, 이덕트(1)와 동축선라인으로 배치되는 엔진축 호스(2)는 후커버(3b)와 연결되어 있다.In addition, the connecting portion of the front and rear cover (3a, 3b) is the clip 10 is fastened to the connecting flange portion, the inlet side of the front cover (3a) is connected to the duct (1) which is the outside air inlet, the duct ( The engine shaft hose 2, which is arranged coaxially with 1), is connected to the rear cover 3b.
이와 같은 구조를 갖는 본 발명에 따른 에어클리너의 공기흐름을 살펴보면, 도 2의 화살표 방향으로 외부공기가 덕트(1)를 통해 유입되면 전커버(3a)의 원만한 공기 흐름통로에 의해 통기저항이 저감되면서 원통형 필터부(4)를 거치게 되는데, 이때 이 필터부(4)의 여과면적이 원통형으로 되어 있어서 종래 사각형 필터부의 여과 면적에 비해 증가된 상태이기 때문에 여과효율이 증대된다.Looking at the air flow of the air cleaner according to the present invention having such a structure, when the outside air flows through the duct 1 in the direction of the arrow of Figure 2, the ventilation resistance is reduced by the smooth air flow passage of the front cover (3a) While passing through the cylindrical filter portion 4, at this time, the filtration area of the filter portion 4 is cylindrical, so that the filtration efficiency is increased because of the increased state compared to the filtration area of the conventional rectangular filter portion.
이렇게 상기 필터부(4)를 거친 정화된 공기는 엔진측 호스(2)쪽으로 빠져 흡기 다기관(도면에 도시되어 있지 않음)으로 공급된다.한편, 상기 전커버(3a)는 와이어 골격부(8)에 면사직조물(9)이 부착되어 코팅처리 되는 구성을 가지므로, 이러한 전커버(3a)의 표면에는 미세한 천공이 형성되며 이를 통해 역화의 발생에 의한 고압 가스가 새어나갈 수 있게 된다.그러므로, 통기성이 전혀 없는 합성수지로 제작되었던 종래의 에어클리너와는 달리 역화 발생시 형성되는 고압을 커버면에서 모두 받지 않고 천공을 통해 외부로 적절히 분산시키게 되므로, 에어클리너 자체의 파손을 방지하게 된다.또한, 면사직조물(9)의 표면에는 코팅처리를 하게 되므로, 외부로부터의 이물질은 효과적으로 차단될 수 있게 된다.The purified air having passed through the filter part 4 is thus fed to the engine side hose 2 and supplied to the intake manifold (not shown). The front cover 3a is provided with a wire skeleton part 8. Since the cotton woven fabric 9 is attached to and coated on the surface of the front cover 3a, fine perforations are formed on the surface of the front cover 3a so that the high-pressure gas due to the backfire can leak out. Unlike conventional air cleaners, which were made of no synthetic resin, since the high pressure formed when the backfire occurs, the cover surface is properly distributed to the outside through perforation without receiving all of the high pressure, thereby preventing damage to the air cleaner itself. Since the surface of (9) is coated, foreign matter from the outside can be effectively blocked.
상기와 같이 본 발명에 따른 에어클리너는 외부공기가 유입되는 덕트와 엔진측 호스를 동축선상으로 배치하여 통기저항을 저감시키고 여과 면적의 증대로 여과효율이 증대될 뿐만 아니라, 유선형의 구조로 설치되기 때문에 소음 및 진동 저감 효과를 지닌다.As described above, the air cleaner according to the present invention has coaxially arranged the duct and the engine side hose into which the outside air flows to reduce the ventilation resistance and increase the filtration area to increase the filtration efficiency, and to be installed in a streamlined structure. Because of the noise and vibration reduction effect.
