Description
본 발명은 자동차의 동력조향장치에 관한 것으로, 특히 동력조향장치를 구성하는 랙과 피니언밸브조립체의 충격을 완화하고, 최대회전시 충격을 주지않도록 하는 자동차의 동력조향장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power steering apparatus of a motor vehicle, and more particularly, to a power steering apparatus of a motor vehicle which mitigates the impact of a rack and pinion valve assembly constituting the power steering apparatus and does not give an impact during maximum rotation.
일반적으로 자동차의 조향장치는 자도차의 진행방향을 임의로 바꾸기 위해 조향을 하는 장치로서, 운전자가 직접 조향조작을 하여 그 조작력을 조향 기어 및 링크 등에 전달하기 위해 조향핸들과 조향축 및 칼럼 등으로 구성된 조작기구와, 상기 조향축의 회전을 감속하여 조작력을 크게 함과 동시에 조작기구의 운동방향을 바꾸어 링크기구에 전달하는 기어장치 및, 기어 기구의 작동을 앞바퀴에 전달하고 또 좌우 바퀴의 관계위치를 바르게 지지하기 위해 피트먼 아암과 드래그 아암, 너클 아암 및 타이 로드 등으로 구성된 링크기구로 이루어져 있다.In general, a steering device of a vehicle is a device for steering to arbitrarily change the driving direction of a self-driving car, and is composed of steering wheel, steering shaft, column, etc. to transmit steering force to steering gear and link by the driver directly steering operation. The operation mechanism, the gear unit for reducing the rotation of the steering shaft to increase the operating force and changing the direction of movement of the operation mechanism to the link mechanism, and transmitting the operation of the gear mechanism to the front wheels, It consists of a link mechanism consisting of a pitman arm, a drag arm, a knuckle arm and a tie rod to support it.
제1도는 종래 자동차의 동력조향장치를 도시한 것으로, 피니언밸브조립체(10)가 오일시일(20)과 니들베어링(30)을 매개로 타이로드(41)가 설치된 기어박스(40)에 장착되고, 이 기어박스(40)의 내부로 랙기어부(51)를 갖춘 랙(50)이 끼워져 상기 피니언밸브조립체(10)의 피니언(11)과 맞물려 회전 및 이동되도록 설치되어 타이어의 방향을 설정할 수 있도록 설치됨과 더불어, 이 랙(50)의 랙기어부(51)와 피니언(11)이 치합되는 반대쪽에는 오일시일(60)과 오일링(70) 및 랙스톱퍼(80)가 장착되어 유체의 누출을 방지함과 더불어 랙(50)의 이동을 제한하도록 설치되어 있다.1 shows a power steering apparatus of a conventional vehicle, in which a pinion valve assembly 10 is mounted on a gearbox 40 in which a tie rod 41 is installed via an oil seal 20 and a needle bearing 30. The rack 50 having the rack gear portion 51 is inserted into the gearbox 40 to be engaged with the pinion 11 of the pinion valve assembly 10 so as to rotate and move, thereby setting the direction of the tire. In addition, the oil seal 60, the oil ring 70 and the rack stopper 80 are mounted on the opposite side to which the rack gear 51 and the pinion 11 of the rack 50 are engaged. In addition to preventing the movement of the rack 50 is installed to limit.
상기와 같이 구성된 피니언밸브조립체(10)가 회전하면서 랙(50)을 좌우로 직선이동하게 하고, 이렇게 좌우로 직선운동하는 랙(50)에 의해 차륜이 일정각도로 선회되게 된다.As the pinion valve assembly 10 configured as described above rotates the rack 50 linearly to the left and right, the wheel is pivoted at a predetermined angle by the rack 50 linearly moving left and right.
그런데 이러한 동력조향장치는 최대회전시 조향핸들을 최대한 돌릴 경우 랙스톱퍼(80)가 부딪치는 둔탁한 소리를 느끼게 되어 조향핸들의 최대회전시 조종안정감이 없게 되는 결점이 있었다.However, such a power steering device has a drawback in that when the steering wheel is turned as much as possible during the maximum rotation, the rack stopper 80 feels a dull sound and there is no steering stability at the maximum rotation of the steering wheel.
이에 본 발명은 상기한 결점을 해소하기 위해 안출된 것으로, 랙의 변위를 감지하여 엔진콘트롤유니트로 신호를 보내게 되면 오일펌프를 작동시켜 조향축과 연결된 피니언밸브조립체의 회전을 제어할 수 있도록 된 변위센서가 기어박스에 설치된 구조로, 동력조향장치를 구성하는 랙과 피니언밸브조립체의 충격을 완화하고, 최대회전시 충격이 없도록 된 자동차의 동력조향장치를 제공함에 그 목적이 있다.Therefore, the present invention has been devised to solve the above-mentioned drawback, and when the displacement of the rack is sensed and sent to the engine control unit, the oil pump can be operated to control the rotation of the pinion valve assembly connected to the steering shaft. Displacement sensor is installed in the gearbox, the purpose of the rack and pinion valve assembly constituting the power steering to mitigate the impact, and to provide a power steering device of the vehicle that there is no impact at maximum rotation.

본 발명은, 피니언밸브조립체(10)가 오일시일(20)과 니들베어링(30)을 매개로 타이로드(41)가 설치된 기어박스(40)에 장착되고, 이 기어박스(40)의 내부로 랙기어부(51)를 갖춘 랙(50)이 끼워져 상기 피니언밸브조립체(10)의 피니언(11)과 맞물려 회전 및 이동되도록 설치되어 타이어의 방향을 설정할 수 있도록 설치됨과 더불어, 이 랙(50)의 랙기어부(51)와 피니언(11)이 치합되는 반대쪽에는 오일시일(60)과 오일링(70)이 설치되어 유체의 누출을 방지할 수 있도록 된 자동차의 동력전달장치에 있어서, 상기 랙(50)의 돌출부(52)의 위치를 감지하여 엔진콘트롤유니트(100)로 신호를 보내게 되면 오일펌프(200)의 출구에 위치한 리턴파이프라인(210)의 밸브를 조절하여 오일펌프(200)와 압력계(400) 및 피니언밸브조립체(10)의 압력을 저하시켜 스티어링휠의 회전을 무겁게 하여 조향축과 연결된 피니언밸브조립체(10)의 회전을 제어할 수 있도록 된 변위센서(300)가 기어박스(40)의 소정위치에 설치된 구조로 되어 있다.According to the present invention, the pinion valve assembly 10 is mounted to the gearbox 40 in which the tie rod 41 is installed via the oil seal 20 and the needle bearing 30, and into the gearbox 40. The rack 50 having the rack gear portion 51 is fitted to be engaged with the pinion 11 of the pinion valve assembly 10 so as to rotate and move so as to set the direction of the tire. The rack gear unit 51 and the pinion 11 of the opposite side is engaged with the oil seal 60 and the oil ring 70 is installed in the power transmission device of the vehicle to prevent the leakage of fluid, the rack When the position of the protrusion 52 of the 50 is detected and sent to the engine control unit 100, the oil pump 200 is controlled by adjusting the valve of the return pipe line 210 located at the outlet of the oil pump 200. And pressure of the pressure gauge 400 and the pinion valve assembly 10 to reduce the rotation of the steering wheel. Displacement sensor 300 to control the rotation of the pinion valve assembly 10 connected to the steering shaft has a structure installed in a predetermined position of the gear box (40).
여기서 상기 리버스수단(210)은, 상기 엔진콘트롤유니트(100)와 오일펌프(200)의 사이에 설치된 압력계(400)의 압력이 일정압 이상으로 도달되지 않으면 오일펌프(200)의 유체가 리싸이클을 갖을 수 있도록 설치되어 있다.Here, the reverse means 210, if the pressure of the pressure gauge 400 installed between the engine control unit 100 and the oil pump 200 does not reach above a certain pressure, the fluid of the oil pump 200 is to recycle the recycle. It is installed to have.
이에 따라 상기 변위센서(300)에서 감지한 변위량의 입력치를 엔진콘트롤유니트(100)에서 판독하여 일정치 이상이 되면 리버스수단(210)에 의해 오일펌프(200)의 압력을 급속히 감소시켜 피니언밸브조립체(10)의 회전을 무겁게 하여 차륜의 최대회전시 충격음이 발생하지 않게 한다.Accordingly, when the input value of the displacement amount sensed by the displacement sensor 300 is read by the engine control unit 100 and exceeds a predetermined value, the pressure of the oil pump 200 is rapidly reduced by the reverse means 210 so that the pinion valve assembly can be obtained. The rotation of (10) is made heavy so that the impact sound does not occur at the maximum rotation of the wheel.
한편 상기 변위센서(300)에서 감지한 변위량의 입력치를 엔진콘트롤유니트(100)에서 판독하여 일정치 이하이면 오일펌프(200)의 압력을 증가시켜 피니언밸브조립체(10)의 회전을 가볍게 만든다.On the other hand, the input value of the displacement amount sensed by the displacement sensor 300 is read by the engine control unit 100, if the predetermined value or less to increase the pressure of the oil pump 200 to lighten the rotation of the pinion valve assembly (10).
상기 변위센서(300)의 일정영역에서는 평상시와 동일한 유체의 흐름을 주고, 일정영역의 밖에서는 유체의 유량을 조절하게 된다.In a certain region of the displacement sensor 300 gives a flow of the same fluid as usual, and outside the predetermined region to control the flow rate of the fluid.
이상 설명한 바와 같이 본 발명에 따른 자동차의 동력조향장치에 의하면, 랙(50)의 변위를 감지하여 엔진콘트롤유니트(100)로 신호를 보내게 되면 오일펌프(200)를 작동시켜 조향축과 연결된 피니언밸브조립체(10)의 회전을 제어할 수 있도록 된 변위센서(300)가 기어박스(40)에 설치되어, 랙과 피니언밸브조립체의 충격을 완화하고, 최대회전시 충격이 없도록 만들어 줄 수 있는 효과가 있다.As described above, according to the power steering apparatus of the vehicle according to the present invention, when the displacement of the rack 50 is detected and a signal is sent to the engine control unit 100, the oil pump 200 is operated to connect the pinion to the steering shaft. Displacement sensor 300 that can control the rotation of the valve assembly 10 is installed in the gearbox 40, to mitigate the impact of the rack and pinion valve assembly, the effect that can be made to be no impact during maximum rotation There is.
