본 발명은 감쇠력 가변형 쇽업소버에 관한 것으로서 더욱 더 상세하게는 전자기 유도 현상에 의해 쇽업소버에 충진되어 있는 오일 유량이 차량의 운행상태에 따라 변화되면서 감쇠력이 가변되도록 함으로써, 차량을 운행 중 선회 등을 수행 시, 차량의 롤링을 억제하여 차실에 탑승한 승원이 편안한 승차감을 얻을 수 있도록 함과 동시에 양호한 조종안정성을 얻을 수 있도록 하는 감쇠력 가변형 쇽업소버 에 관한 것이다.The present invention relates to a variable damping force shock absorber, and more particularly, by changing the oil flow rate filled in the shock absorber according to the driving state of the vehicle by the electromagnetic induction phenomenon, so that the damping force is varied, thereby turning the vehicle while driving. When performing, the present invention relates to a damping force variable shock absorber that suppresses rolling of a vehicle to allow a passenger in a cabin to obtain a comfortable ride and at the same time obtain a good steering stability.

일반적으로 현가장치는 차축과 차체 프레임 사이에 연결되어 주행 중 노면으로부터 전달되는 진동이나 충격을 흡수하여 승차감과 자동차의 안정성을 향상시키는 장치로서, 주행 중에 노면으로부터 받는 충격을 완화하는 섀시 스프링, 차체의 상하진동을 억제하여 승차감을 좋게 하는 쇽업소버로 이루어진다. In general, the suspension system is connected between the axle and the body frame to absorb vibrations or shocks transmitted from the road surface while driving to improve ride comfort and stability of the vehicle. It is composed of shock absorber which suppresses up and down vibration and improves riding comfort.

이러한 현가장치는 프론트 현가장치와 리어 현가장치로 대별되고, 프론트 현가장치는 앞차축의 형식에 따라 차축 현가식과 독립 현가식으로 나눌 수 있다. These suspensions are classified into front suspensions and rear suspensions, and the front suspensions can be divided into axle suspension and independent suspensions according to the type of the front axle.

독립 현가식은 차축을 분할하여 놓은 것으로, 양쪽 바퀴가 상호간에 간섭받지 않고 단독적으로 움직일 수 있도록 하여 승차감이나 자동차의 안전성을 향상시킬 수 있다. Independent suspension is a split axle, so that both wheels can move independently without interference between each other can improve the ride comfort and safety of the car.

이러한 독립 현가식은 위시본형, 맥퍼슨형, 스위차축형, 트레일링 링크형 등이 있다.Such independent suspensions include a wishbone type, a McPherson type, a swiveling axle type and a trailing link type.

현가장치 중 맥퍼슨형 현가장치에 대한 예로서, 한국 특허 공개공보 제 2000-004017호, 제 1999-035385호, 제 1998-040143호 등에 제시되어 있다.As an example of the McPherson type suspension device, it is presented in Korean Patent Laid-Open Publication Nos. 2000-004017, 1999-035385, 1998-040143, and the like.

현가장치는 서로 반대되는 특성인 승차감과 조종안정성의 쌍방을 만족시키기 위한 목적으로 저속 주행 시 쇽업소버의 감쇠력을 낮추어 승차감을 향상시키고, 고속 주행 시 쇽업소버의 감쇠력을 높게 하여 조종안정성을 확보하는 쇽업소버 감쇠력 제어기구를 사용한다.Suspension system improves ride comfort by reducing damping force of shock absorber at low speed and improves ride comfort at high speed while satisfying both of riding comfort and steering stability. Use absorber damping force control mechanism.

다시 말하면, 조종안전성과 승차감은 서로 상반된 특성을 가지고 있어 어느 한쪽을 만족시키면 다른 한쪽이 나빠지는 경향이 있으므로 이의 해결을 위해 차량 의 정보를 이용, 쇽업소버 측 오일 통로의 크기 또는 오일 통로를 통과하는 오일량을 조절하여 쇽업소버의 감쇠력을 액티브하게 조절하는 기술들이 적용되어 왔다.In other words, the steering safety and the ride comfort have opposite characteristics, so if one side is satisfied, the other side tends to be bad, so the information of the vehicle can be used to solve the problem. Techniques for actively adjusting the damping force of the shock absorber by adjusting the oil amount have been applied.

이러한, 감쇠력 가변형 쇽업소버 구조로써 한국 특허 공개공보 제 2003-0042604호 공보에 제시되어 있다.Such a damping force variable shock absorber structure is disclosed in Korean Patent Laid-Open Publication No. 2003-0042604.

도 1은 종래의 감쇠력 가변형 쇽업소버를 도시한 단면도이다.1 is a cross-sectional view showing a conventional damping force variable shock absorber.

도 1에 도시한 바와 같이, 종래의 감쇠력 가변형 쇽업소버 구조는 내부에 오일이 충진된 튜브(110)와, 상기 튜브(110)의 내부를 따라 왕복 이동하는 피스톤(120)과, 상기 피스톤 (120)에 그 단부가 고정되어 피스톤(120)을 왕복 이동시키는 피스톤 로드(130)로 구성되어 있다.As shown in FIG. 1, the conventional damping force variable shock absorber structure includes a tube 110 filled with oil therein, a piston 120 reciprocating along the inside of the tube 110, and the piston 120. Its end is fixed to the) is configured of a piston rod 130 for reciprocating the piston (120).

한편, 상기 피스톤(120)에는 오리피스(121)가 관통되게 형성되어 있다, Meanwhile, an orifice 121 is formed in the piston 120 to penetrate through the piston 120.

이와 같이 구성된 종래 감쇠력 가변형 쇽업소버는, 승차감을 우선적으로 향상시킬 필요가 있을 경우에는, 오리피스(121)의 내경을 크게 형성하여 감쇠력을 크게 조정하는 방식으로 감쇠력을 조종하게 된다.The conventional damping force variable shock absorber configured as described above controls the damping force in such a manner that the inner diameter of the orifice 121 is increased to adjust the damping force largely when it is necessary to improve the riding comfort first.

그러나, 전술한 감쇠력 가변형 쇽업소버는 차량의 좌우 양측에 각각 설치되는 쇽업소버가 동일한 감쇠력을 갖도록 설치되는 관계로, 차량을 운행 중 선회 등을 수행 시 외륜에 위치하게 되는 쇽업소버는 원심력에 의해 범핑이 발생되면서 차량의 롤링을 증대시켜 차실에 탑승한 승원이 불안감을 느끼게 됨은 물론, 조정안정성이 저하되는 문제점이 있었다.However, the above-described damping force variable shock absorber is installed so that the shock absorbers respectively installed on both the left and right sides of the vehicle have the same damping force. As a result of this, the rolling of the vehicle was increased to make the crew in the cabin feel insecure, and there was a problem in that the adjustment stability was lowered.

따라서 종래에도 상기와 같은 문제점을 해결하기 위해 노면 상태와 운전 조건에 따라 차체 높이를 변화시켜, 주행 안전성과 승차감을 동시에 확보하기 위한 전자제어현가장치(electronic controlled suspension)를 개발하여 사용하고 있다.Therefore, in order to solve the above problems, the vehicle height is changed according to road conditions and driving conditions, and an electronic controlled suspension is developed and used to simultaneously secure driving safety and ride comfort.

그러나 이러한 종래 전자제어현가장치는 쇽업소버의 튜브에 충진되어 있는 오일의 양이 솔레노이드나 스텝모터에 의해 제어되면서 감쇠력이 조절되는 것인 관계로, 상기 쇽업소버의 외부에 별도의 솔레노이드나 스텝모터를 장착시켜야 한다.However, such a conventional electronic control suspension has a damping force that is controlled while the amount of oil filled in the tube of the shock absorber is controlled by the solenoid or the step motor, so that a separate solenoid or step motor is provided outside the shock absorber. It must be fitted.

이로 인해 차량을 조립시 부품수가 증가하고 작업 공정이 증가하여 작업자가 불편함을 느끼게 됨은 물론, 차량을 제작시 제작비용이 상승하게 되는 문제점이 있었다.As a result, the number of parts increases and the working process increases when assembling the vehicle, thereby making the worker feel uncomfortable, and there is a problem that the manufacturing cost increases when manufacturing the vehicle.

본 발명의 목적은 전자기 유도 현상에 의해 쇽업소버에 충진되어 있는 오일 유량이 차량의 운행상태에 따라 변화되면서 감쇠력이 조절되도록 함으로써, 차량을 운행 중 선회 등을 수행 시, 차량의 롤링을 억제하여 차실에 탑승한 승원이 편안한 승차감을 얻을 수 있도록 함과 동시에 양호한 조종안정성을 얻도록 하는 감쇠력 가변형 쇽업소버를 제공하는데 그 목적이 있다.An object of the present invention is to adjust the damping force while the flow rate of the oil filled in the shock absorber is changed according to the operating state of the vehicle by the electromagnetic induction phenomenon, to suppress the rolling of the vehicle when turning the vehicle during driving, etc. The object of the present invention is to provide a damping force variable shock absorber that enables a crew to get a comfortable ride and at the same time obtain a good steering stability.

이러한 본 발명의 목적은, 행정공간(111)이 형성되어 있는 튜브(110)와, 상기 행정공간(111)에 승하강 가능하게 설치되는 피스톤(120)과, 상기 피스톤(120)이 튜브(110)의 행정공간(111) 상하부로 왕복운동이 이루어지도록 하는 피스톤 로드(130)로 구성되어 지는 것에 있어서, 상기 튜브(110)가 구리나 은등과 같이 자석 이 붙지않는 비자성체 금속으로 제작되고, 상기 튜브(110)의 행정공간(111)에 설치된 피스톤(120)이 승하강되도록 하는 피스톤 로드(130)에는 자력을 발생시키는 자석(140)이 설치되는 것에 의해 달성된다.The object of the present invention, the tube 110, the stroke space 111 is formed, the piston 120 is installed to be able to move up and down in the stroke space 111, the piston 120 is the tube 110 In the piston rod 130 for reciprocating the upper and lower strokes of the stroke space (111) of the), the tube 110 is made of a non-magnetic metal, such as copper or silver, without a magnet, The piston rod 130 which is installed in the stroke space 111 of the tube 110 is raised and lowered by the magnet 140 for generating a magnetic force is achieved.

한편, 상기 자석(140)은 노면이 울퉁불퉁한 비포장 도로에서는 차 높이를 높여 차체를 보호하고, 고속도로와 같이 고속 주행이 가능한 도로에서는 차 높이를 낮추어 공기 저항을 줄여 줄수 있도록 하는 만큼만 자력이 있도록 함으로써, 상기 자석(140)의 자력에 의해 쇽업소버(100)가 원활한 감쇠력을 갖도록 하게됨이 가장 바람직 하다.On the other hand, the magnet 140 protects the vehicle body by increasing the height of the car on the uneven road surface bumpy road, by lowering the height of the car on the road capable of high-speed running, such as a highway to reduce the air resistance as much as possible, Most preferably, the shock absorber 100 has a smooth damping force by the magnetic force of the magnet 140.

이 구성에 의하면, 피스톤 로드(130)가 작동시, 상기 피스톤 로드(130)에 설치된 자석(14)에 의해 전자기 유도현상이 발생하면서 튜브(110)내에 맴돌이 전류가 발생하게 되고, 상기 맴돌이 전류는 다시 자기장을 형성하게 되며, 상기 자기장은 피스톤 로드(130)의 움직임을 방해하는 방향으로 힘이 발생하면서 쇽업소버(100)의 감쇠력을 적절하게 변화시키게 된다.According to this configuration, when the piston rod 130 is operated, a eddy current is generated in the tube 110 while electromagnetic induction occurs by the magnet 14 installed in the piston rod 130, and the eddy current is To form a magnetic field again, the magnetic field is appropriately to change the damping force of the shock absorber 100 while generating a force in a direction that interferes with the movement of the piston rod (130).

따라서, 차량을 운행시 양호한 조종안정성을 얻을 수 있으며 동시에 편안한 승차감을 얻을 수 있게 된다.Therefore, it is possible to obtain good steering stability when driving the vehicle and at the same time obtain a comfortable riding comfort.

한편, 상기 자석(140)을 전자석으로 구성하여, 상기 전자석에 공급되는 전원량에 따라 전자석의 자력 세기가 조절되도록 함으로써, 차량을 제작시 전류의 세기를 조절하여 쇽업소버(100)의 감쇠력이 조절되도록 하여도 무방하다.On the other hand, by configuring the magnet 140 as an electromagnet, the magnetic strength of the electromagnet is adjusted according to the amount of power supplied to the electromagnet, the damping force of the shock absorber 100 is adjusted by adjusting the strength of the current when the vehicle is manufactured. You may make it possible.

이하, 첨부된 도면에 의하여 본 발명의 그 기술적 구성을 상세히 설명하면 다음과 같다Hereinafter, the technical configuration of the present invention according to the accompanying drawings in detail as follows.

도 2는 본 발명인 감쇠력 가변형 쇽업소버의 구성을 보인 개략도이다.Figure 2 is a schematic diagram showing the configuration of the damping force variable shock absorber of the present invention.

본 발명의 감쇠력 가변형 쇽업소버는 차체와 차륜사이에 장착되어 상·하 진동에 대한 감쇠력을 발휘하는 쇽업소버(100)에 있어서, 상기 쇽업소버(100)의 튜브(110)가 구리나 은등과 같이 자석이 붙지않는 금속으로 제작되고, 상기 튜브(110)의 행정공간(111)에 설치된 피스톤(120)이 승하강되도록 하는 피스톤 로드(130)에는 자력을 발생시키는 자석(140)이 설치된다.The damping force variable shock absorber of the present invention is mounted between the vehicle body and the wheel, and the shock absorber 100 exhibits a damping force against up and down vibration, wherein the tube 110 of the shock absorber 100 is made of copper or silver. A magnet 140 for generating a magnetic force is installed on the piston rod 130 that is made of a metal to which the magnet does not adhere, and the piston 120 installed in the stroke space 111 of the tube 110 is lifted up and down.

물론, 상기 자석(140)을 전자석으로 구성하여, 상기 전자석에 공급되는 전류의 세기에 따라 자력이 변화되는 것에 의해 쇽업소버(100)의 감쇠력이 변화되도록 하여도 무방하다.Of course, the magnet 140 may be configured of an electromagnet, and the damping force of the shock absorber 100 may be changed by changing the magnetic force according to the strength of the current supplied to the electromagnet.

이와 같이 구성되는 본 발명은, 차량을 운행 중 쇽업소버(100)가 범프 및 리바운드 시, 피스톤 로드(130)를 따라 피스톤(120)이 구리나 은 등과 같이 자석이 붙지않는 비자성체 금속으로 제작된 튜브(110)의 행정공간(111)을 따라 승,하강 된다.According to the present invention configured as described above, when the shock absorber 100 is bumped and rebounded while driving a vehicle, the piston 120 is made of a non-magnetic metal such as copper or silver that does not adhere to the piston rod 130. It is raised and lowered along the administration space 111 of the tube 110.

이때, 상기 피스톤 로드(130)에 설치된 자석(140)은 상기 피스톤 로드(140)의 움직임에 따라 전자기 유도현상이 발생하면서 튜브(110)에 맴돌이 전류를 발생시키게되고, 상기 맴돌이 전류는 다시 자기장을 형성하면서 피스톤 로드(130)의 움직임을 방해하는 방향으로 힘을 발생시키면서 감쇠력이 변화되어지게 된다.In this case, the magnet 140 installed in the piston rod 130 generates an eddy current in the tube 110 while electromagnetic induction occurs as the piston rod 140 moves, and the eddy current again generates a magnetic field. While forming, the damping force is changed while generating a force in a direction that obstructs the movement of the piston rod 130.

따라서 이러한 본 발명은 전자기 유도 현상에 의해 쇽업소버에 충진되어 있 는 오일 유량이 차량의 운행상태에 따라 변화되면서 감쇠력이 조절되도록 함으로써, 차량을 운행 중 선회 등을 수행 시, 차량의 롤링을 억제하여 차실에 탑승한 승원이 편안한 승차감을 얻을 수 있도록 함과 동시에 양호한 조종안정성을 얻도록 하는 등의 효과가 있는 매우 유용한 발명이다.Therefore, the present invention is to control the damping force while the flow rate of the oil filled in the shock absorber is changed according to the operating state of the vehicle by the electromagnetic induction phenomenon, thereby suppressing the rolling of the vehicle when turning the vehicle, etc. It is a very useful invention that has the effect of obtaining a comfortable driving comfort at the same time as the occupant in the cabin to obtain a comfortable ride feeling.
