Description
본 발명은 자동차 기관(engine)의 흡기장치에 관한 것으로서, 드로틀밸브의 구조를 개선하여 흡기저항 및 흡기 유동음이 저감되도록 하는 기관의 드로틀밸브 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intake apparatus of an automobile engine, and more particularly, to a throttle valve structure of an engine that improves the structure of the throttle valve to reduce intake resistance and intake flow noise.
일반적으로 자동차 기관은 복수개의 실린더가 형성되는 실린더블록의 상부에 복수개의 연소실이 형성되는 실린더헤드가 결합되어 상기 실린더와 연소실이 연통되며, 상기 실린더헤드의 일측에 흡기밸브에 의해 개폐되도록 하는 흡기구들이 각기 연소실에 연통되게 형성되고, 실린더헤드의 타측에 배기밸브에 의해 개폐되도록 하는 배기구들이 각기 연소실 타측에 연통되게 형성되어 있다. 또한, 실린더헤드의 일측에는 제1도에 도시되는 바와 같이, 흡기다기관(11)이 흡기구들에 연통되도록 취부되고, 흡기다기관(11)에 서지탱크(surge tank)(10)가 연통되게 연결되며, 서지탱크(10)의 선단부에 원통형의 드로틀바디(throttle body)(20)가 연통되게 연결되어 있다. 또한, 드로틀바디(2)의 내부에 드로틀밸브(21)가 회동 가능하게 장착되고, 드로틀밸브(21)의 일단부가 드로틀바디(20)의 외측에 장치되는 드로틀레버(22)에 구동 가능하게 연결되며, 드로틀레버(22)가 가속페달에 연결되는 가속케이블(accel cable)(23)에 회전구동 가능하게 연결되어 있다.Generally, in an automobile engine, a cylinder head having a plurality of combustion chambers is coupled to a cylinder block on which a plurality of cylinders are formed, so that the cylinder and the combustion chamber communicate with each other. Intake ports for opening / And exhaust ports for opening and closing by an exhaust valve are formed on the other side of the cylinder head so as to communicate with the other side of the combustion chamber. 1, the intake manifold 11 is connected to the intake ports, and the surge tank 10 is connected to the intake manifold 11 so as to be communicated with the intake manifold 11 And a cylindrical throttle body 20 is connected to the front end of the surge tank 10 so as to communicate with each other. A throttle valve 21 is rotatably mounted inside the throttle body 2 and one end of the throttle valve 21 is driveably connected to the throttle lever 22 provided on the outside of the throttle body 20 And the throttle lever 22 is rotatably connected to an accelerator cable 23 connected to the accelerator pedal.
이와같이 구성되는 자동차 기관은, 실린더헤드의 각 연소실에 장치되는 흡기밸브와 배기밸브가 각기 일정 주기로 개폐되며, 흡기밸브가 열리면 실린더 내부의 부압에 의해 흡기구와 흡기다기관(11)을 통해 서지탱크(10) 및 드로틀바디(20) 내부에 부압이 작용되어, 가속페달을 조작하면 가속케이블(23)과 드로틀레버(22)에 의해 드로틀밸브(21)가 희동되는 것에 의해 드로틀바디(20)의 내부 통로 개구량이 조절되도록 하므로, 연소실로 유입되는 공기량이 조절되도록 한다.When an intake valve is opened, a negative pressure inside the cylinder causes the intake valve and the exhaust valve to be opened and closed at regular intervals in the combustion chamber of the cylinder head. The intake valve and the intake manifold 11 are connected to each other through a surge tank 10 And the throttle valve 21 is activated by the accelerator cable 23 and the throttle lever 22 when the accelerator pedal is operated by a negative pressure in the throttle body 20 and the inside passage of the throttle body 20, So that the amount of air flowing into the combustion chamber can be controlled.
그러나 이러한 종래 기관은, 드로틀밸브(21)가 원형의 판재로 형성되어 있기 때문에, 흡입공기가 드로틀바디(20) 내부를 통과할 때 제2도에 도시되는 바와 같이, 드로틀밸브(21) 안쪽 외곽부에 와류가 발생되어 흡기저항이 크게 되고, 기류음이 발생되는 문제점이 있었다.However, in this conventional engine, since the throttle valve 21 is formed of a circular plate, when the intake air passes through the inside of the throttle body 20, as shown in FIG. 2, There is a problem that a vortex is generated in the portion, the intake resistance is increased, and the air flow noise is generated.
본 발명은 상기 종래와 같은 문제점을 보완하기 위해, 드로틀밸브의 구조 및 조작구조를 개선하여 흡기저항 및 기류음이 저감되도록 하는 데 그 목적이 있다.SUMMARY OF THE INVENTION It is an object of the present invention to improve the structure and operating structure of a throttle valve to reduce the intake resistance and the air flow noise in order to overcome the above problems.

먼저, 본 발명도 제3도 내지 제5도에 도시되는 바와 같이, 기관의 흡기다기관(11)에 서지탱크(10)가 연통되게 연결되고, 서지탱크(10)의 선단부에 원통형의 드로틀바디(20)가 연통되게 연결되며, 드로틀바디(20)의 내부에 드로틀밸브(25)가 장착되고, 드로틀밸브(25)의 일단부가 가속페달에 연결되는 가속케이블(23)에 구동 가능하게 연결되는 것은 종래와 같다.3 to 5, the surge tank 10 is connected to the intake manifold 11 of the engine so as to communicate with the intake manifold 11. The surge tank 10 has a cylindrical throttle body The throttle valve 25 is mounted inside the throttle body 20 and one end of the throttle valve 25 is drivably connected to the acceleration cable 23 connected to the accelerator pedal As in the prior art.
단, 본 발명은 드로틀바디(20)의 내주면에 단턱부를 갖는 슬라이드부가 형성되고, 외주면에 걸림턱이 돌출되는 타원형의 드로틀밸브(25)가 드로틀바디(20)의 내부에 이동이 가능하게 장착되어, 드로틀바디(20)의 슬라이드부에 드로틀밸브(25)의 걸림턱이 제한 이동 가능하게 지지되고, 드로틀밸브(25)의 후단부에 서지탱크(10)를 관통하는 구동바아(26)가 연결되며, 서지탱크(10)의 후면부에서 구동바아(26)가 가속케이블(23)에 구동 가능하게 연결됨을 그 기술적 구성상의 기본 특징으로 한다.However, in the present invention, an elliptical throttle valve 25 having a slide portion having a stepped portion formed on the inner circumferential surface of the throttle body 20 and having an engagement protrusion protruding from the outer circumferential surface thereof is movably mounted inside the throttle body 20 A driving bar 26 passing through the surge tank 10 is connected to the rear end of the throttle valve 25 so as to be connected to the sliding portion of the throttle body 20 And the drive bar 26 is drivably connected to the acceleration cable 23 at the rear portion of the surge tank 10 as a basic feature of the technical structure.
여기에서, 서지탱크(10)는 후단부에 관통구멍이 형성되고, 상기 관통구멍 외측부에 소정 공간을 갖는 브라켓(27)이 취부되며, 브라켓(27)의 공간 내부에 스프링(28)이 장착되어, 구동바아(26)의 후단부가 서지탱크(10)의 후단 관통구멍을 관통하여 브라켓(27) 내부의 스프링(28)에 일측방향으로 탄지된다.A through hole is formed in the rear end of the surge tank 10, a bracket 27 having a predetermined space is attached to the outside of the through hole, and a spring 28 is mounted inside the space of the bracket 27 The rear end of the drive bar 26 penetrates through the rear end through hole of the surge tank 10 and is biased to the spring 28 inside the bracket 27 in one direction.
이와같이 구성되는 본 발명은, 가속페달을 조작하면 가속케이블(23)에 의해 구동바아(26) 및 드로틀밸브(25)가 연동되어, 드로틀밸브(25)가 드로틀바디(20)의 슬라이드부에서 축방향으로 이동되며, 드로틀밸브(25)가 축방향으로 이동되면 타원의 외주면과 드로틀바디(20) 내부면 사이의 간격이 가변되므로, 유동 공기량이 조절되게 되며, 가속페달을 놓으면 스프링(28)의 탄발력에 의해 구동바아(26) 및 드로틀밸브(25)의 위치가 복원되게 된다.When the accelerator pedal is operated, the drive bar 26 and the throttle valve 25 are interlocked by the acceleration cable 23 so that the throttle valve 25 is moved from the slide portion of the throttle body 20 to the axis of the throttle body 20, When the throttle valve 25 is moved in the axial direction, the distance between the outer surface of the ellipse and the inner surface of the throttle body 20 is changed, so that the amount of flow air is adjusted. When the accelerator pedal is released, The position of the driving bar 26 and the throttle valve 25 is restored by the elastic force.
한편, 본 발명은 드로틀바디(20)의 내부를 유동하는 공기가 타원형으로 형성된 드로틀밸브(25)의 외주면을 따라 유동하게 되며, 기류가 유선형으로 유동되므로 공기저항이 저감되고, 유동시 발생되는 기류음이 저감되도록 한다.Meanwhile, since the air flowing inside the throttle body 20 flows along the outer circumferential surface of the elliptical throttle valve 25 and the airflow flows in a streamlined manner, the air resistance is reduced, Let the sound be reduced.
이와같이 구성되고 작동되는 본 발명은, 드로틀밸브의 구조가 유선형의 타원형으로 형성되고 축방향으로 이동되어 통과공기의 유량을 조절하도록 되므로, 드로틀밸브면을 접촉하는 흡입공기가 유선형으로 유동되고, 이로인해 공기저항 및 유동음이 저감되도록 하는 효과를 갖는다.According to the present invention constructed and operated as described above, since the structure of the throttle valve is formed into a streamlined elliptical shape and is moved in the axial direction to adjust the flow rate of the passing air, the intake air contacting the throttle valve surface flows in a streamline manner, The air resistance and the flow noise are reduced.
