본 발명은 가변용량 진공펌프에 관한 것으로, 더욱 상세하게는 타원 펌프하 우징 내부에 가변적으로 움직일 수 있는 진원 인너하우징을 장착해 진공도의 유무에 따라 진공펌프의 저압부과 고압부의 체적을 가변적으로 제어해 마찰을 감소시켜며, 연비 및 출력 그리고 구성부품의 내구 수명을 증대시키는 가변용량 진공펌프에 관한 것이다.The present invention relates to a variable-capacity vacuum pump, and more particularly, to the variable elliptical pump housing mounted with a variable inner housing to variably control the volume of the low pressure portion and the high pressure portion of the vacuum pump according to the degree of vacuum. The present invention relates to a variable displacement vacuum pump that reduces friction and increases fuel economy, power and durability of components.

자동차에서는 브레이크, 엔진회전수 보상장치, EGR 벨브, VGT 작동 등에 공압을 이용 한다. 소형 차량의 경우 진공압력을 이용하는데, 이런 진공압력은 가솔린 엔진의 경우 흡기다기관 입구에 공기 유량을 조절하는 쓰로틀벨브가 있어 엔진 운전중에는 자연적으로 부압이 형성되어 이 압력을 호스 등으로 연결하여 사용 한다. In cars, pneumatics are used for brakes, engine speed compensators, EGR valves, and VGT operation. In the case of small vehicles, vacuum pressure is used. In the case of gasoline engines, there is a throttle valve that regulates the air flow rate at the intake manifold inlet, so that negative pressure is naturally formed during engine operation. .

디젤엔진의 경우 이런 벨브가 없어 별도의 진공펌프를 엔진에 장착해서 사용한다. 일반적인 승용디젤엔진의 경우에는 발전기의 회전축에 직결되어 회전되거나 캠사프트에 연결되어 구동된다.In the case of diesel engines, there is no such valve, so a separate vacuum pump is used in the engine. In the case of a general passenger diesel engine, it is directly connected to the rotating shaft of the generator and driven or connected to the cam shaft.

도 1은 종래 기술에 따른 가변용량 진공펌프를 도시한 도면이다. 도면을 참조하면, 로터(2)가 회전하여 원심력이 형성되면 베인(4)이 돌출되어 펌프하우징(6) 내면에 밀착하고, 오일의 작용으로 구성 부품에 기밀이 유지되어 "A,B,C,D" 구역이 형성하게 된다.1 is a view showing a variable displacement vacuum pump according to the prior art. Referring to the drawings, when the rotor 2 rotates to form a centrifugal force, the vanes 4 protrude and adhere to the inner surface of the pump housing 6, and the airtightness of the components is maintained by the action of oil. , "D" zone will form.

상기 "A,B,C,D" 공간은 로터(2) 회전에 의해 용적이 변하게 된다. A구역이 회전하여, B구역 위치로 가면 용적이 커지면서 압력은 떨어져, 부압이 발생된다. 그리고 부압이 형성되어 흡기구(8)와 차압이 발생되면 첵크밸브 밸브(10)가 열려 흡기구(8)로부터 공기가 유입된다. 유입된 공기는 D구역으로 가면서 용적이 적어져 배유구(12)로 공기와 오일이 배출된다.The space "A, B, C, D" is changed in volume by the rotation of the rotor 2. When zone A rotates to the zone B, the volume increases, the pressure drops, and negative pressure is generated. When the negative pressure is formed to generate the differential pressure with the intake port 8, the check valve valve 10 opens to allow air to flow from the intake port 8. As the air enters the area D, the volume decreases, and air and oil are discharged to the drain hole 12.

따라서 흡기구(8)에 연결된 회로에서 공기가 빠져 나가 면서 부압이 낮아지고, 공기가 다 빠지면 완전진공 상태 (-760mmHg) 가 된다. Sol. Valve, Brake 등의 작동(진공도의 저하)은 진공펌프(14)에 대기가 유입 되는 것을 의미한다. 상기한 바와 같이 베인의 움직임과 용적의 변화로 프릭션 및 고열이 발생하는 문제점이 있다.Therefore, the negative pressure is lowered as air escapes from the circuit connected to the intake port 8, and when the air is exhausted, it becomes a full vacuum state (-760 mmHg). Sol. Operation of the valve, brake, etc. (decrease in the degree of vacuum) means that the air flows into the vacuum pump 14. As described above, there is a problem in that friction and high fever occur due to the change of the vane movement and volume.

상기한 진공펌프(14)는 진공도에 관계없이 계속 일을 해서, 필요 없는 부하를 유발해 성능을 과 연비 성능을 떨어뜨리며, 작동 특성상 압축과 이완을 고회전으로 반복하여 공급 윤활유의 열화를 촉진시키는 등 개선의 여지가 많았다.The vacuum pump 14 continues to work irrespective of the degree of vacuum, causing unnecessary loads and lowering the performance of the fuel economy, and, by operating characteristics, compression and relaxation are repeated at high rotation to promote deterioration of the supply lubricant. There was a lot of room for improvement.

현재의 진공펌프는 최고 출력점에서 약3~4마력의 마찰손실을 가져오고있으며, 배유구의 오일온도가 최고 출력점에서 ~150??로 엔진 오일 열화를 촉진시키게 되는 문제점이 있었다.The current vacuum pump has a friction loss of about 3 ~ 4 horsepower at the highest output point, and the oil temperature of the drain port is ~ 150 ?? at the highest output point to promote engine oil deterioration.

상기한 바와 같이 이루어지는 종래기술의 문제점을 해소하기 위하여 제안된 것으로 본 발명의 목적은 타원 펌프하우징 내부에 가변적으로 움직일 수 있는 진원 인너하우징을 장착해 진공도의 유무에 따라 진공펌프의 저압부과 고압부의 체적을 가변적으로 제어해 마찰을 감소시켜며, 연비 및 출력 그리고 구성부품의 내구 수명을 증대시키는 가변용량 진공펌프를 제공한다.The object of the present invention is to solve the problems of the prior art made as described above, and an object of the present invention is to equip the elliptic pump housing with a variable inner housing that can move variably in the volume of the low pressure portion and the high pressure portion of the vacuum pump depending on the degree of vacuum. Variable-variability vacuum pumps that reduce friction and increase fuel economy, power and durability of components.

도면을 참조하면, 가변용량 진공펌프(20)는 서지탱크(22)와 연결되는 펌프하우징(24)내에 회전하게 설치된 로터(26)에 방사상으로 베인(28)이 조립 구성되는 진공펌프에 있어서, 타원형상이고, 직선 가이드면(30)을 형성한 타원 펌프하우징(32)과; 상기 타원 펌프하우징(32)내에 방사형으로 베인(28)을 설치한 로터(26)와; 상기 로터(26)와 베인(28)을 내장하면서 타원펌프하우징(32)내를 이동하게 전,후진 회전축(34)으로 연결 설치된 진원 인너하우징(36)과; 상기 진원 인너하우징(36)에 연결 설치된 전,후진 회전축(34)을 회전시키게 타원 펌프하우징(32) 외부에 전자제어장치(38)의 전기적 신호로 구동하게 설치된 정,역 모타(40)로 구성된다.Referring to the drawings, the variable displacement vacuum pump 20 is a vacuum pump in which the vanes 28 are assembled radially to the rotor 26 rotatably installed in the pump housing 24 connected to the surge tank 22, An elliptic pump housing (32) having an elliptical shape and forming a straight guide surface (30); A rotor (26) radially provided with vanes (28) in the elliptic pump housing (32); An inner circle housing 36 connected to the front and rear rotary shafts 34 to move the inside of the elliptic pump housing 32 while the rotor 26 and the vanes 28 are embedded therein; It consists of a forward and reverse motor 40 installed to drive the electric signal of the electronic control device 38 to the outside of the elliptic pump housing 32 to rotate the forward and backward rotation shaft 34 connected to the inner circle housing 36. do.

상기 전자제어장치(38)는 브레이크(42) 작용을 감지하도록 설치된 브레이크 감지센서(44)와, 서지탱크(22)에 설치된 접점식 다이어프램 센서(46)와, 상기 브레이크감지센서(44)와 접점식 다이어프램 센서(46)의 신호로 기 설정된 정보에 의하 여 판단하여 정,역모타(40)를 제어하게 된다.The electronic control device 38 includes a brake detection sensor 44 installed to detect the action of the brake 42, a contact diaphragm sensor 46 installed in the surge tank 22, and a contact with the brake detection sensor 44. The positive and reverse motors 40 are controlled by judging based on predetermined information as a signal of the formula diaphragm sensor 46.

가변용량 진공펌프(20)의 타원 펌프하우징(32)은 종래의 펌프 하우징과 달리 내부 구조가 진원이 아니며, 진원 인너하우징(36)이 움질일 수 있도록 타원 펌프하우징(32)은 진원 인너하우징(36)과의 중심거리가 존재하게 된다. 즉, 진원 인너하우징(36)은 외주면에는 직선 구간(36-1)이 형성되어 있어 타원 펌프하우징(32)내의 이동을 용이하게 한다.Unlike the conventional pump housing, the elliptic pump housing 32 of the variable capacity vacuum pump 20 does not have an internal structure, and the elliptic pump housing 32 has a circular inner housing so that the inner circle housing 36 may move. There is a central distance with 36). That is, the round inner housing 36 has a straight section 36-1 formed on the outer circumferential surface to facilitate movement in the elliptic pump housing 32.

상기한 바와 같이 이루어지는 본 발명의 작용을 설명하면, 진원 인너하우징(36)에는 정,역모터(40)와, 전,후진 회전축(34)으로 연결되어 있고 타원 펌프하우징(32)의 직선 가이드면(30) 구간의 안내로 움직이게 된다. When explaining the operation of the present invention made as described above, the circular inner housing 36 is connected to the forward and reverse motor 40, and the forward and backward rotation shaft 34, and the linear guide surface of the elliptic pump housing 32 It moves to the guidance of section 30.

진원 인너하우징(36)이 보통의 진공펌프처럼 정중앙에 위치되고 있는데, 이때 A,B,C,D로 표시된 각 영역이 중심 로터(26)의 회전에 의해 용적이 증가하면서 진공을 형성하게 되고, 감소하면서 압축을 하게 되어 오일을 배출하게 된다.The circular inner housing 36 is located at the center of the center like a normal vacuum pump, where each area indicated by A, B, C, and D forms a vacuum as the volume increases due to the rotation of the central rotor 26. Compression decreases, draining the oil.

이때 베인(28)은 로터(26)에 의하여 회전하면서 왕복 직선운동을 하게 되면서 왕복운동 및 회전운동과 압축 및 이완에 따른 부하가 베인(28)에 작용해서 마찰과 펌프 구동에 의한 부하가 최대로 형성되는 지점이다.At this time, the vane 28 is reciprocating linear motion while rotating by the rotor 26, the load due to the reciprocating motion and rotational movement and compression and relaxation act on the vane 28 to maximize the load due to friction and pump driving It is the point where it is formed.

진원 인너하우징(36)이 최대로 이동하여 A,B,C,D의 구역에서 용적이 같은 상태가 되어 진공펌프(20)의 작동 부하가 없고 진공도 형성되지 않게 된다. 따라서 베인(28)도 왕복운동을 하지 않고, 또한 용적의 변화가 없기 때문에 베인(28)의 부하도 없어 마찰력이 크게 떨어진 상태가 된다.The circular inner housing 36 moves to the maximum, so that the same volume is in the region of A, B, C, and D, so that there is no operating load of the vacuum pump 20 and no vacuum is formed. Therefore, since the vane 28 also does not reciprocate and there is no change in volume, there is no load of the vane 28 and the frictional force is greatly dropped.

진원 인너하우징(36)이 위치하면 그 위치에 따라 펌프 작동 부하 및 마찰이 감소 또는 증가 하게 된다. When the inner circle housing 36 is located, the pump operating load and friction are reduced or increased depending on the position.

그리고 진공펌프(20)에 DC모터 내장형 정,역모터(40)을 설치하여 진공도에 따라 가변적으로 진원 인너하우징(36)을 전,후진 회전축(34)으로 이동시켜 진공도를 조절하게 된다. And by installing the DC motor built-in forward and reverse motor 40 in the vacuum pump 20 to move the round inner housing 36 to the forward and backward rotation shaft 34 to adjust the degree of vacuum variable according to the degree of vacuum.

이에 따라 가변적으로 진원 인너하우징(36)이 이동함에 따라 용적의 변화가 적어져서 진공펌프(20)를 구동하는 부하 및 마찰력은 떨어지고 펌프의 진공 능력은 감소하게 된다. Accordingly, as the circular inner housing 36 variably moves, the change in volume decreases, thereby reducing the load and frictional force for driving the vacuum pump 20 and reducing the vacuum capability of the pump.

따라서 현재의 진공도에 알맞은 위치로 진원 인너하우징이 움직이면서 진공도를 필요한 만큼 유지하게 된다.Therefore, the inner circle housing moves to a position suitable for the current vacuum degree, thereby maintaining the vacuum degree as necessary.

이에 따라 이렇게 하면 진공펌프의 운전 상태를 항상 최적으로 유지 할 수 있어 운전시간에 따른 전체 프릭션량이 저감되어 연비 및 출력 내부 구성품의 내구 수명을 증대 그리고 오일의 열 부하 감소로 열화 현상을 개선 할 수 있게 된다.In this way, the operating state of the vacuum pump can be optimally maintained at all times, reducing the overall friction amount according to the operating time, improving the fuel economy and durability of the internal components of the output, and improving the deterioration phenomenon by reducing the heat load of the oil. Will be.

그리고 진공 써지탱크(22)에 접점식 다이아프람 센서(46)를 장착한다. 접점 부위에는 압전 소자가 설치 되어있어 압력에 따라 선형적으로 볼트 값이 출력되어 현재의 진공상태를 전달받은 전자제어장치는 목표 진공 압에 도달하면 진원 인너하우징(36)을 공회전 영역으로 이동시켜 펌프 구동 부하를 감소시키게 된다. 그리고 목표 진공 값이 되도록 정,역모터(40)를 전자제어장치(38)가 피드백제어를 하게 된다.Then, the contact type diaphragm sensor 46 is mounted on the vacuum surge tank 22. The piezoelectric element is installed at the contact point, and the voltage is output linearly according to the pressure, and the electronic control device that receives the current vacuum state moves the circular inner housing 36 to the idling region when the target vacuum pressure is reached. It reduces the driving load. In addition, the electronic controller 38 performs feedback control on the forward and reverse motors 40 so as to achieve the target vacuum value.

즉, 브레이크 작동 일때는 진공 펌프 최대 작동 상태로 이동되게 하고, 엔진이 고속이고 진공도가 충분 할 때는 공회전 영역으로 이동되도록 한다. 그리고 목 표 진동압 달성시 진원 인너하우징은 움직여 진공도를 유지한다. That is, when the brake is actuated, the vacuum pump is moved to the maximum operating state, and when the engine is high speed and the degree of vacuum is sufficient, the engine is moved to the idling region. And when the target vibration pressure is achieved, the inner circle housing moves to maintain the vacuum degree.

이상에서 살펴본 바와 같이 현재의 진공도에 알맞은 위치로 진원 인너하우징이 움직이면서 진공도를 필요한 만큼 유지하게 되는 효과가 있다.As described above, since the inner circle housing moves to a position suitable for the current vacuum degree, there is an effect of maintaining the vacuum degree as necessary.

이렇게 하면 진공펌프의 운전 상태를 항상 최적으로 유지 할 수 있어 운전시간에 따른 전체 프릭션량이 저감되어 연비 및 출력 내부 구성품의 내구 수명을 증대하게 되는 효과가 있다.In this way, the operating state of the vacuum pump can be maintained optimally at all times, thereby reducing the overall friction amount according to the operating time, thereby increasing fuel economy and endurance life of the output internal components.

그리고 오일의 열 부하 감소로 열화 현상을 개선 할 수 있는 효과가 있다.And there is an effect that can improve the deterioration phenomenon by reducing the heat load of the oil.

가변적으로 진원 인너하우징이 그림3 위치에서 그림4위치로 이동함에 따라 용적의 변화가 적어져서 진공펌프를 구동하는 부하는 및 마찰력은 떨어지고 펌프의 진공 능력은 감소하게 된다. As the variable inner housing moves variably from the position of Figure 3 to the position of Figure 4, the change in volume is small, so that the load and frictional force for driving the vacuum pump are reduced, and the vacuum capacity of the pump is reduced.

현재의 진공도에 알맞은 위치로 인너하우징이 움직이면서 진공도를 필요한 만큼 유지하게 된다.The inner housing is moved to a position that is appropriate for the current vacuum level to maintain the vacuum degree as needed.

또, 이렇게 하면 진공펌프의 운전 상태를 항상 최적으로 유지 할 수 있어 운전시간에 따른 전체 프릭션량이 저감되어 연비 및 출력 내부 구성품의 내구 수명을 증대 그리고 오일의 열 부하 감소로 열화 현상을 개선 할 수 있는 효과가 있다.In this way, the operating state of the vacuum pump can be maintained optimally at all times, which reduces the overall friction amount according to the operating time, thereby improving the fuel economy and durability of output internal components, and improving the deterioration phenomenon by reducing the heat load of oil. It has an effect.
