Description
본 고안은 자동차용 동력조향장치의 동력실린더에 관한 것으로, 특히 동력실린더에 조향력향상장치가 설치되어져 고속주행시 조향휠의 조작력이 향상될 수 있도록 된 자동차용 동력조향장치의 동력실린더에 관한 것이다.The present invention relates to a power cylinder of a power steering apparatus for automobiles, and more particularly, to a power cylinder of a power steering apparatus for automobiles in which a steering force enhancing apparatus is installed in the power cylinders so that the operating force of the steering wheel can be improved during high-speed driving.
일반적으로 동력조향(Power Steering)은 엔진에 의해 구동되는 오일펌프의 유압으로 스티어링오일의 조작력을 가볍게 하는 장치의 총징으로써, 작동원리는 압력을 높일 오일을 조향장치와 연동하는 실린더에 넣어 피스톤의 문동에 의해 핸들의 조작력을 가볍게 하는 것으로, 파워실린더에 유입되는 오일의 양은 컨트롤밸브에 의해 조정되며, 핸들의 조작을 신속히 할수록 오일의 유입양을 많아지게 되며, 핸들의 조작을 멈추면 오일의 유입도 멈추는 구조로 되어 있다.In general, power steering is a mass of a device that lightens the operating force of the steering oil by the hydraulic pressure of an oil pump driven by an engine.The principle of operation is to put oil into a cylinder that interlocks with a steering device to increase pressure, and then to operate the piston. By reducing the operating force of the handle, the amount of oil flowing into the power cylinder is controlled by the control valve, and the speed of operation of the handle increases the inflow of oil. It is structure to stop.
동력 조향을 사용하게 되면 첫째, 조작력을 작게 할 수 있으므로 조향기어를 자유로이 선택할 수 있고, 둘째 노면에서의 공격에 의한 조향휠의 킥 백(Kick Back)을 방지할 수 있으며, 셋째, 앞바퀴의 시미 오션(Shimmy Motion)을 감소하는 효과가 있다.When using power steering, first, the operating force can be reduced, so the steering gear can be freely selected, and second, the kick back of the steering wheel can be prevented by the attack on the road surface, and third, the seamy of the front wheel It has the effect of reducing (Shimmy Motion).
이러한 동력조향의 일반적인 구성부는 제1도에 도시된 바와 같이, 배력작용의 동력원인 유압을 발생시키도록 된 동력장치(100)와, 이 동력장치(100)에서의 유압을 앞바퀴의 조향력으로 바꾸도록 된 작동장치(200) 및, 이 작동장치(200)에서의 유로를 개폐하도록 된 제어장치(300)로 이루어져 있다.This general configuration of the power steering, as shown in Figure 1, the power unit 100 is to generate the hydraulic pressure as a power source of the back action, and to change the hydraulic pressure in the power unit 100 to the steering force of the front wheels. The operating device 200, and the control device 300 to open and close the flow path in the operating device 200.
여기서, 상기 동력장치(100)는 엔진으로 구동되는 오일펌프(10)와 고유압을 규제하도록 된 압력릴리프밸브 및 유량을 조정하도록 된 플로우컨트롤밸브(11)로 이루어져 있고, 상기 작동장치(200)는 동력실린더(20)가 주요부이며, 상기 제어장치(300)는 조향휠(30)을 조작함으로써 유로를 개폐하게 되며 안전밸브(31)가 설치되어 있다.Here, the power device 100 is composed of an oil pump 10 driven by the engine, a pressure relief valve to regulate the high pressure and a flow control valve 11 to adjust the flow rate, the operating device 200 The power cylinder 20 is the main part, the control device 300 is opened and closed the flow path by operating the steering wheel 30, the safety valve 31 is installed.
그리고, 상기 동력실린더(20)는 유체가 유입 또는 배출되도록 제1개구홀(21a) 및 제2개구홀(21b)이 형성된 챔버(21)와, 이 챔버(21)내에서 피스톤로드(22)를 매개로 작동되도록 된 피스톤(23)으로 이루어져 있다.The power cylinder 20 includes a chamber 21 in which a first opening 21a and a second opening 21b are formed so that fluid is introduced or discharged therein, and a piston rod 22 in the chamber 21. It consists of a piston (23) to be operated through the.
따라서, 주행중 좌측방향으로 선회주행을 하기 위해 조향휠(30)을 좌측으로 회전시키게 되면 유체가 제1개구홀(21a)을 통해 챔버(21)내로 유입됨과 동시에 피스톤로드(22)가 좌측으로 이동되어 상기 챔버(21)내의 유체가 피스톤(23)의 작동압에 의해 제2개구홀(21b)을 통해 배출되는 바, 이때 상기 제2개구홀(21b)을 통해 배출된 유체는 좌측바퀴로 이동되어 좌측바퀴를 작동시킴으로써 차체가 좌측방향으로 선회주행을 실시할 수 있게 된다.Therefore, when the steering wheel 30 is rotated to the left to turn in the left direction while driving, the fluid flows into the chamber 21 through the first opening 21a and the piston rod 22 moves to the left. The fluid in the chamber 21 is discharged through the second opening 21b by the operating pressure of the piston 23, and the fluid discharged through the second opening 21b moves to the left wheel. Thus, by operating the left wheel, the vehicle body can turn in the left direction.
또한, 주행중 우측방향으로 선회주행을 하기 위해 조향휠(30)을 우측으로 회전시키게 되면 유체가 전술한 바의 역순인 제2개구홀(21b)로 유입되어 제1개구홀(21a)을 통해 배출되는 바, 이때 상기 제1개구홀(21a)을 통해 배출된 유체는 우측바퀴를 작동시킴으로써 차체가 우측방향으로 선회주행을 실시할 수 있게 된다.In addition, when the steering wheel 30 is rotated to the right in order to turn in the right direction while driving, the fluid flows into the second opening 21b in the reverse order as described above and is discharged through the first opening 21a. In this case, the fluid discharged through the first opening 21a may operate the right wheel so that the vehicle body may rotate in the right direction.
그러나 이와 같은 종래의 동력조향장치에 의하면, 저속으로의 주행시에는 조향휠(30)의 조작력이 향상되어 운전자가 적은 힘으로도 용이하게 선회주행을 실시 할 수 있는 장점은 있으나, 고속으로의 주행시에는 조향휠(30)이 가벼워지는 특성에 의해 선회주행시 상기 조향휠(30)의 조작력이 저감되어 운전자가 조작하지 않은 임의의 방향으로 조작됨으로 인해 안전사고가 발생되는 문제점이 있었다.However, according to such a conventional power steering device, the driving force of the steering wheel 30 is improved when driving at a low speed, so that the driver can easily turn with a small force, but when driving at a high speed The steering wheel 30 has a problem in that a safety accident occurs due to the operation force of the steering wheel 30 being reduced by turning the steering wheel 30 in any direction not operated by the driver when turning by the characteristic of being lighter.
이에 본 고안은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 동력실린더에 조향력향상장치를 설치하여 고속주행시 조향휠이 가벼워지는 현상을 제거함으로써 상기 조향휠의 조작력을 향상시켜 안전사고발생을 방지할 수 있도록 된 자동차용 동력조향장치의 동력실린더를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, by installing a steering force enhancing device in the power cylinder to eliminate the phenomenon that the steering wheel lighter during high-speed driving to improve the operating force of the steering wheel to prevent the occurrence of safety accidents It is an object of the present invention to provide a power cylinder of a power steering apparatus for automobiles.

And a chamber 21 having a first opening 21a and a second opening 21b to allow fluid to flow in or out of the power cylinder 20, and a piston rod in the chamber 21. In the power steering apparatus of an automobile comprising a piston (23) adapted to be operated via a medium (22), the power cylinder (20) is electrically connected to a controller (500) connected to a vehicle speed sensor (400) to detect a traveling speed. Steering force to be operated by control signal The apparatus 600 is provided.
여기서, 상기 조향력향상장치(600)는 외관을 형성하도록 된 2개의 하우징(60, 70)과, 금속재질로써 상기 하우징(60, 70)내에서 전기적인 자성(磁性)에 의해 작동되도록 된 작동부재(61, 71) 및, 이 작동부재(61, 71)의 하면과 일체로 결합되어 상기 챔버(21)의 일부분을 개폐하도록 된 밸브부재(62, 72)로 이루어진다.Here, the steering force enhancing device 600 is the two housings (60, 70) to form an appearance, and the operating member to be operated by electrical magnetic in the housing (60, 70) made of a metal material 61 and 71 and valve members 62 and 72 which are integrally coupled with the lower surfaces of the actuating members 61 and 71 to open and close a part of the chamber 21.
따라서, 주행중 일측 방향으로 선회주행을 하기 위해 조향휠(30)의 조작을 시작하게 되면 주행속도가 차속센서(400)에 의해 감지되되, 먼저 주행속도가 저속으로 감지되면 상기 차속센서(400)의 제어신호에 의해 제어기(500)가 작동되어 조향력향상장치(600)로 전기적인 신호를 보내게 되는 바, 이때 하우징(60, 70)의 상부에는 전자력이 발생됨과 더불어 작동부재(61, 71)가 전자력에 의해 상기 하우징(60, 70)의 상부에 밀착되도록 이동되고, 상기 작동부재(61, 71)의 이동과 동시에 밸브부재(62, 72)도 이동되어 챔버(21)를 개방시키게 되며, 이로 인해 상기 챔버(21)의 통로가 막힘이 없이 원활한 통로를 형성함으로서 운전자가 원활하게 조향조작을 실시할 수 있게 된다.Therefore, when the operation of the steering wheel 30 is started in order to turn in one direction while driving, the driving speed is detected by the vehicle speed sensor 400, but when the driving speed is detected at a low speed, the vehicle speed sensor 400 The controller 500 is operated by the control signal to send an electrical signal to the steering force enhancing device 600. At this time, an electromagnetic force is generated on the upper portions of the housings 60 and 70, and the operating members 61 and 71 are Moved to be in close contact with the upper portion of the housing (60, 70) by the electromagnetic force, the valve member 62, 72 is also moved to open the chamber 21 at the same time as the operation member (61, 71) moves, Due to this, the passage of the chamber 21 forms a smooth passage without clogging, thereby allowing the driver to smoothly operate the steering.
