이를 첨부한 도면에 의거하여 본 발명을 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings as follows.
도 1은 본 발명에 의한 시스템의 구성도로서, 도 1에 도시한 바와 같이, 고속, 저속주행시 차량의 속도를 제어하는 전자 제어 유닛(ECU)과, 전자 제어 유닛으로부터 제어된 차량속도에 따라 유입되는 유체를 제어하는 솔레노이드 밸브(10)와, 유체 입출력을 위해 형성한 입출력홀(20),(20')과, 압력에 의해 유체를 공급하는 펌프(30)와, 유체가 누설되지 않도록 충전하는 패킹(40)과, 솔레노이드 밸브에 의해 하강하는 피스톤(50)과, 피스톤의 왕복운동을 지지하는 웨어링(60)과, 피스톤하강시 압축되는 요크스프링(70)과, 스프링 압축시 랙바(90)의 움직임을 제어하는 서포트요크(80)로 구성된다.1 is a configuration diagram of a system according to the present invention, as shown in FIG. 1, an electronic control unit (ECU) for controlling the speed of a vehicle during high speed and low speed driving, and inflow according to a vehicle speed controlled from the electronic control unit. The solenoid valve 10 for controlling the fluid to be controlled, the input and output holes 20, 20 'formed for the fluid input and output, the pump 30 for supplying the fluid by the pressure, and the fluid to prevent leakage Packing 40, piston 50 descending by solenoid valve, wear ring 60 for supporting reciprocating movement of piston, yoke spring 70 compressed when piston descends, rack bar 90 during spring compression It consists of a support yoke 80 for controlling the movement of the.
도면에 도시한 부호중 100은 요크플러그, 110은 6각 너트(HEX)를 나타낸다.In the drawings, 100 denotes a yoke plug and 110 denotes a hexagon nut (HEX).
이와 같이 구성된 본 발명의 작용효과를 실시도면에 따라 설명하면 다음과 같다.When explaining the operation and effect of the present invention configured as described above according to the drawings.
먼저 전자 제어 유닛(ECU)에서는 고속 또는 저속 주행시 차량속도를 입력받아 솔레노이드 밸브(10)를 제어한다.First, the electronic control unit (ECU) controls the solenoid valve 10 by receiving a vehicle speed during high speed or low speed driving.
이렇게 솔레노이드 밸브(10)를 제어해줌에 따라 고속주행시 입력홀(20)로 유입되는 유체를 솔레노이드 밸브(10)에 의해 제어된다.As the solenoid valve 10 is controlled in this way, the fluid flowing into the input hole 20 during high speed driving is controlled by the solenoid valve 10.
따라서 솔레노이드 밸브(10)에 의해 제어된 유체는 출력홀(20')을 통해 펌프(30)에 입력되고 입력된 유체는 펌프의 압력에 의해 솔레노이드 밸브(10)로 입력된다.Therefore, the fluid controlled by the solenoid valve 10 is input to the pump 30 through the output hole 20 'and the input fluid is input to the solenoid valve 10 by the pressure of the pump.
이러한 상태에서 웨어링(60)에 의해 피스톤(50)이 하강하면 피스톤의 하강에 의하여 요크스프링(70)이 압축된다.When the piston 50 is lowered by the wear ring 60 in this state, the yoke spring 70 is compressed by the lowering of the piston.
이때 요크스프링(70)의 압축에 따라 서포트요크(80)가 랙바(90)의 움직임을 제어함으로써 선형적으로 변하는 R/P 파워스티어링 조향필링을 얻게 되는 것이다.At this time, the support yoke 80 controls the movement of the rack bar 90 according to the compression of the yoke spring 70 to obtain a linearly changing R / P power steering steering peeling.
이상에서와 같이 본 발명은 기존의 R/P 파워스티어링 기어박스에 비해 구조가 간단하고, 피니언 제어방식에 비해 가공이 용이함으로 코스트를 절감시킬 수 있게 하였으며, 또한 고속, 저속 주행시 선형적으로 변하는 R/P 파워스티어링 조향필링을 향상시켜주는 효과가 있다.As described above, the present invention is simpler in structure than the conventional R / P power steering gearbox, and is easy to process compared to the pinion control method, thereby reducing the cost, and also linearly changing at high speed and low speed driving. / P Power steering Improves steering peeling.
