본 발명은 자동차의 파워 스티어링 펌프용 유압 클러치에 관한 것이다.The present invention relates to a hydraulic clutch for a power steering pump of a motor vehicle.
종래의 파워 스티어링 펌프는 임펠러의 축에 풀리를 설치하여 크랭크 샤프트 풀리와 연결된 워터 펌프 풀리와 벨트로 연결하여 크랭크 샤프트의 회전에 따라 펌프축이 회전되면 임펠러가 회전되도록 한 것이다.In the conventional power steering pump, a pulley is installed on the shaft of the impeller, and the water pump pulley connected to the crankshaft pulley is connected to the belt so that the impeller rotates when the pump shaft is rotated according to the rotation of the crankshaft.
그러나, 파워 스티어링은 저속시에는 파워 스티어링 펌프의 높은 압력을 필요로 하지만 점차로 고속이 되면서 파워 스티어링 펌프의 압이 필요없게 된다.However, power steering requires a high pressure of the power steering pump at a low speed, but gradually becomes a high speed, and the pressure of the power steering pump is unnecessary.
그럼에도 불구하고, 종래의 파워 스티어링 펌프는 고속상태에서도 계속해서 엔진에 의하여 회전하고 있기 때문에 불필요한 에너지 손실을 가져오고 있었다.Nevertheless, the conventional power steering pump has caused unnecessary energy loss because it continues to rotate by the engine even at a high speed.
본 발명의 목적은 고속시에 파워 스티어링 펌프가 작동된 않게 하므로서 불필요한 엔진 마력손실을 방지하기 위한 데 있는 것이다.An object of the present invention is to prevent unnecessary engine horsepower loss by preventing the power steering pump from operating at high speed.
본 발명은 상기 목적을 달성하기 위하여, 펌프 하우징 내에 펌프 출구와 연결되는 유로와 압력실을 형성하고; 이 압력실 내에 풀리와 연결되고, 단부에 스플라인이 형성된 구동축과, 임펠러가 축설치되고, 단부에 스플라인이 형성된 피동축을 이격되게 일직선 상으로 설치하며; 상기 구동축과 상기 피동축의 단부에는 유로측 오일압력에 따라 축방향으로 이동 가능하게 스플라인결합되고 오일압력을 받는 압력판이 형성된 연결기어를 설치하고; 상기 오일압력에 반력을 작용하는 스프링을 상기 압력판의 일측에 설치한 것이다.In order to achieve the above object, the present invention provides a flow path and a pressure chamber connected to the pump outlet in the pump housing; A drive shaft connected to the pulley in the pressure chamber, the drive shaft with the spline formed at the end, and the impeller being shaft-mounted, and the driven shaft with the spline formed at the end spaced apart in a straight line; An end gear of the drive shaft and the driven shaft is spline-coupled to be movable in the axial direction according to the oil pressure on the flow path side, and a connection gear having a pressure plate for receiving oil pressure is provided; A spring that reacts to the oil pressure is installed on one side of the pressure plate.
본 발명은 상기와 같은 구성에 따라, 저속시에는 압력실에 작용하는 오일압력이 스프링력 보다 크므로 연결기어가 구동축과 피동축에 공히 연결되고, 고속시에는 압력실에 작용하는 오일압력이 스프링력 보다 작으므로 연결기어가 피동축으로 이동하여 구동축에서 분리된다.According to the above configuration, since the oil pressure acting on the pressure chamber at the low speed is greater than the spring force, the connecting gear is connected to the driving shaft and the driven shaft at the low speed, and the oil pressure acting on the pressure chamber at the high speed is the spring. Since it is smaller than the force, the connecting gear moves to the driven shaft and is separated from the drive shaft.
이하 본 발명의 실시예를 첨부된 도면에 의하여 설명한다.Embodiments of the present invention will now be described with reference to the accompanying drawings.
본 발명은 제1도와 같이 펌프 하우징(1) 내에 펌프 출구와 연결되는 유로(2)와 압력실(3)을 형성하고; 이 압력실(3) 내에 풀리(4)와 연결되고, 단부에 스플라인(5)이 형성된 구동축(6)과, 임펠러(미도시)가 축설치되고, 단부에 스플라인(5')이 형성된 피동축(7)을 이격되게 일직선 상으로 설치하며; 상기 구동축(6)과 상기 피동축(7)의 단부에는 유로(2)측 오일압력에 따라 축방향으로 이동가능하게 스플라인결합되고 오일압력을 받는 압력판(8)이 형성된 연결기어(9)를 설치하고; 상기 오일압력에 반력을 작용하는 스프링(10)을 상기 압력판(8)의 일측에 설치한 것이다.The present invention forms a flow passage 2 and a pressure chamber 3 connected to the pump outlet in the pump housing 1 as shown in FIG. 1; The driving shaft 6 which is connected to the pulley 4 in this pressure chamber 3, the drive shaft 6 in which the spline 5 was formed in the edge part, and the impeller (not shown) are shaft-mounted, and the driven shaft in which the spline 5 'was formed in the edge part. (7) is installed in a straight line apart; At the end of the drive shaft 6 and the driven shaft 7 is provided a connecting gear 9 having a pressure plate 8 which is spline-coupled in the axial direction in accordance with the oil pressure on the flow path 2 and receives an oil pressure. and; The spring 10 acting on the oil pressure is installed on one side of the pressure plate 8.
상기 연결기어(9)의 내면에도 상기한 구동축(6)의 스플라인(5)과 피동축(7)의 스플라인(5')에 각각 스플라인 결합될 수 있는 스플라인이 형성되어 있다.Splines that can be splined to the splines 5 of the drive shaft 6 and the splines 5 'of the driven shaft 7 are also formed on the inner surface of the connecting gear 9.
구동축(6)에는 베어링(11)이 설치되고, 베어링(11)과 압력실(3)간에는 패킹(12)이 설치되어 있다.A bearing 11 is provided on the drive shaft 6, and a packing 12 is provided between the bearing 11 and the pressure chamber 3.
따라서, 저속시에는 압력실(3)에 작용하는 오일압력이 스프링력 보다 크므로 연결기어(9)가 구동축(6)과 피동축(7)에 공히 연결되어 풀리(4)에 의하여 전달되는 구동력(6)이 피동축(7)에 연결되어 임펠러의 회전에 따른 오일압력이 커져 핸들이 부드럽게 움직인다.Therefore, at low speeds, the oil pressure acting on the pressure chamber 3 is greater than the spring force, so that the driving gear 9 is connected to the drive shaft 6 and the driven shaft 7 in parallel and is transmitted by the pulley 4. (6) is connected to the driven shaft (7), the oil pressure increases due to the rotation of the impeller, the handle moves smoothly.
고속시에는 압력실(3)에 작용하는 오일압력이 스프링력 보다 작으므로 연결기어(9)가 피동축(7)으로 이동하여 구동축(6)에서 분리되어 구동축(7)이 공회전하므로 피동축(7)은 회전하지 않아 엔진 마력손실은 줄어든다.At high speed, since the oil pressure acting on the pressure chamber 3 is smaller than the spring force, the connecting gear 9 moves to the driven shaft 7 and is separated from the driving shaft 6 so that the driving shaft 7 is idling. 7) does not rotate, so horsepower loss is reduced.
상기와 같이 구성된 본 발명은 스프링 상수와 유로의 압을 튜닝하므로서 저압에 의해 우측으로 이동시켜 공회전 가능하며 유로측에 일정압 이상이 걸리며 좌측으로 이동하여 릴리프 밸브의 역할도 가능하게 된다. 이와 같은 본 발명은 펌프를 공회전시킬 수 있으므로 고속시의 불필요한 에너지 손실을 방지할 수 있는 것이다.According to the present invention configured as described above, the spring constant and the pressure of the flow path are tuned to move to the right by the low pressure, and can be idle, and the flow path side takes a certain pressure or more and moves to the left to serve as a relief valve. The present invention as described above can idle the pump, it is possible to prevent unnecessary energy loss at high speed.
