자동차용 파워스티어링(Power Steering)의 펌프(Pump) 구조Pump Structure of Power Steering for Automotive

본 발명은 자동차용 파워스티어링(Power Steering)의 펌프(Pump) 구조에 관한 것으로서, 더욱 상세하게는 파워스티어링 펌프의 풀리를 전자 클러치 방식으로 하여 일정 차속 이상에서는 클러치가 떨어져서 파워스티어링 펌프가 작동하지 않으므로 스티어링이 무겁게 되고, 또한 고속 주행시에는 핸들 오작동으로 인한 사고를 방지할 수 있고, 또한 파워 스티어링 펌프에 클러치만 추가하면 되므로 원가를 저하시켜서 제품의 품질을 향상하고, 소비자의 신뢰성을 향상시키는 자동차용 파워스티어링의 펌프 구조에 관한 것이다.The present invention relates to a pump (pump) structure of the automotive power steering (Power Steering), and more particularly, the pulley of the power steering pump by the electromagnetic clutch method, so that the clutch does not operate because the clutch falls above a certain vehicle speed. The steering power becomes heavy, and in case of high speed driving, it is possible to prevent accidents due to the steering wheel malfunction. Also, only the clutch is added to the power steering pump, which reduces the cost, improves the quality of the product, and improves the consumer's reliability. It relates to the pump structure of the steering.

일반적으로는 자동차용 파워스티어링(Power Steering)은 자동차의 진행방향을 운전자의 편의에 따라 임의로 바꾸기 위한 것으로서, 조향장치를 크게 분류하면 운전자의 조작력을 조향축에 전달하여 운전자의 안전을 도모하는 핸들과, 상기의 핸들에서 발생하는 조타력(주행 위치에 핸들을 꺾는 힘)을 스티어링 기어에 전달하는 조향축이 형성된다.In general, power steering for automobiles is to change the direction of movement of the vehicle arbitrarily according to the driver's convenience. When the steering device is largely classified, the steering wheel and the steering wheel for the driver's safety are transmitted by transmitting the driver's operating force to the steering shaft. The steering shaft which transmits the steering force (the force of bending a steering wheel to a driving position) which arises in the said steering wheel to a steering gear is formed.

그리고 상기 핸들의 회전을 감속함과 동시에 조작력을 증대시키고 운동 방향을 바꾸어 스티어링 링키지(Steering Linkage)에 전달하는 다양한 종류의 스티어링 기어와, 상기 스티어링 기어의 움직임을 앞바퀴에 전달함과 동시에 좌우 바퀴의 관계위치를 올바르게 유지하는 스티어링 링키지로 형성된다.In addition, various types of steering gears which reduce the rotation of the handle and increase the operating force and change the direction of movement to the steering linkage, transmit the movement of the steering gear to the front wheel, and at the same time, the relationship between the left and right wheels. It is formed with a steering linkage that maintains its position correctly.

한편 파워스티어링 펌프의 엔진에 장착되어 크랭크 샤프트가 회전하는 힘을 받아 엔진이 작동되면 항시 작동하는 구조로 되어 있다.On the other hand, it is mounted on the engine of the power steering pump, and the crankshaft is rotated at all times when the engine is operated.

이와 같이 구성되는 자동차용 파워스티어링의 펌프 구조는 원활한 자동차의 코너링을 이룰 수가 없어 제품의 품질을 저하시키고, 또한 속도 감응형 파워스티어링은 제어 방법이 복잡하고 원가가 상승하여 고급차에만 적용함으로서 소형이나 중형을 운전하는 운전자의 코너링에 많은 문제점이 발생되어 제품의 품질을 저하시켜서 소비자의 신뢰성을 떨어뜨리는 문제점 등이 있었다.The pump structure of the automotive power steering system configured as described above does not achieve smooth car cornering and degrades the quality of the product. Also, the speed-sensitive power steering system is applied to only high-end cars because the control method is complicated and the cost increases. Many problems have occurred in the driver's cornering to reduce the quality of the product, there was a problem such as lowering the reliability of the consumer.

본 발명은 이와 같은 종래 기술의 문제점들을 개선하기 위하여 안출된 것으로서, 본 발명의 목적은 파워스티어링 펌프이 풀리를 전자 클러치 방식으로 하여 일정 차속 이상에서는 클러치가 떨어져서 파워스티어링 펌프가 작동하지 않으므로 스티어링이 무겁게 되고, 또한 고속 주행시에는 핸들 오작동으로 인한 사고를 방지할 수 있어 제품의 품질을 향상시킨다.The present invention has been made in order to improve the problems of the prior art, the object of the present invention is the power steering pump pulley by the electromagnetic clutch method, the clutch is dropped over a certain vehicle speed, the power steering pump is not operated, so the steering becomes heavy In addition, it prevents accidents due to steering wheel malfunctions at high speeds and improves product quality.

그리고 본 발명의 다른 목적은 파워스티어링 펌프에 클러치만 추가하면 되므로 원가를 저하시켜서 제품의 품질을 향상하고, 소비자의 신뢰성을 향상시키는 자동차용 파워스티어링의 펌프 구조를 제공하는 데 있다.Another object of the present invention is to provide a pump structure of a power steering vehicle for automobiles, which is required to add only a clutch to the power steering pump, thereby reducing the cost and improving the quality of the product and improving the consumer's reliability.

이와 같은 목적을 실현하기 위하여 이루어진 본 발명에 의한 자동차용 파워스티어링의 펌프 구조는 자동차의 진행방향을 운전자의 편의에 따라 임의로 바꾸기 위한 파워스티어링과 상기 스티어링과 연결되어 오일을 흡입 가압하여 각 윤활부에 공급하는 펌프를 포함하는 자동차용 파워스티어링의 펌프 구조에 있어서, 파워스티어링 펌프의 일측으로 전자 클러치를 형성하는 것을 특징으로 하는 자동차용 파워스티어링의 펌프 구조를 제공한다.The pump structure of the power steering system for a vehicle according to the present invention made to realize the above object is connected to the power steering and the steering to arbitrarily change the driving direction of the vehicle according to the driver's convenience, and suction oil to pressurize each lubrication unit. In the pump structure of the automotive power steering including a pump to supply, it provides a pump structure of the automotive power steering characterized in that the electromagnetic clutch is formed on one side of the power steering pump.
