본 고안은 자동차의 (승용차, 상용차)의 진동을 감쇄시키기 위한 전기 유압식 쇽업소오버에 관한 것으로서, 특히 쇽업소오버 내의 유량조절을 노면상태 및 운동상황에 따라, 미세하게 자동조절하여 감쇄력을 무단변환시켜, 자동차의 승차감 및 조정 안정성을 극대화시키고져 한 것이다.The present invention relates to an electrohydraulic shock absorber for attenuating vibration of a car (commercial car, commercial vehicle). In particular, the flow rate control in the shock absorber is finely adjusted according to road conditions and motion conditions, and thus the damping force is changed without permission. It is intended to maximize the ride comfort and adjustment stability of the car.

주시된 바와 같이 쇽업소오버는 자동차의 차측과 차체에 설치되어 자동차기 주행할때 스프링에 받는 층격에 의해 발생하는 고유진동을 흡수하여, 진동을 빨리 감쇠시켜 승차감을 양호하게 하기 위해 설치하는 것으로서 일반적으로 유압식을 주로 사용하여 진동을 감쇠하였다.As observed, the shock-absorber is installed on the vehicle side and the body of the vehicle to absorb natural vibrations caused by the stratification received by the spring when the vehicle is driven, and to install the vibration to attenuate the vibration quickly to improve the ride comfort. The vibration was damped mainly using hydraulic.

그런데 종래의 유압식, 쇽업소오버는 제2도에 도시한 바와 같이 실린더(22)와 외통(25)을 형성하여 실린더(22)내에 오일공(24)이 형성된 피스톤(22)이 결합되어 있고 실린더(22)와 외통(25) 내부에 오일(26)이 채워져 있다.However, in the conventional hydraulic and shock absorber, as shown in FIG. 2, the cylinder 22 and the outer cylinder 25 are formed, and the piston 22 in which the oil hole 24 is formed in the cylinder 22 is coupled to the cylinder. The oil 26 is filled inside the 22 and the outer cylinder 25.

그리고 실린더(22) 하부에는 실린더(22)와 외통(25)내의 오일(26)이 유동될 수 있도록 밸브스프링(27)을 설치하여 구성되었다.And the lower end of the cylinder 22 was configured by installing a valve spring 27 so that the oil 22 in the cylinder 22 and the outer cylinder 25 can flow.

이와 같이 구성된 쇽업소오버(21)는 단순히 실린더(22)와 외통(25) 내부의 오일(26)을 자동차의 진동에 따라 피스톤(23)에 형성된 오일공(24)과 실린더(22) 하부에 설치된 밸브스프링(27)을 통하여 오일(26)이 화살표 방향으로 피스톤(23)의 상하유동시 유동되면서 주행할때 차측에서 발생되는 진동을 감쇄시켰는바 이는 노면상태 및 운동상황에 따라 크고 적은 상태인 2단의 감쇠력과 크고, 보통, 적은 상태인 3단의 감쇠력만 조정 할수 있어 각단에서의 감쇠력차이가 서로켜서 모오드(MODE) 변환시 승차자의 승차감이 나쁘며 순간적으로 조정안정성을 잃어버리는 문제점이 있었다.The shock absorber 21 configured as described above simply moves the oil 22 inside the cylinder 22 and the outer cylinder 25 to the oil hole 24 formed in the piston 23 and the lower part of the cylinder 22 according to the vibration of the vehicle. When the oil 26 flows in the up and down flow of the piston 23 in the direction of the arrow through the installed valve spring 27, the vibration generated from the vehicle side is attenuated. Only the damping force of two stages and the large, normal, and small three stages of damping force can be adjusted, so that the difference in damping force at each stage is mutually worse, resulting in a poor passenger's riding comfort during mode conversion and loss of adjustment stability.

본 고안은 상기한 종래의 제문제점을 해결하기 위하여 실린더 내부에 설치된 피스톤과 피스톤로드 중앙에 오일관을 형성하되, 오일이 피스톤 상측으로 유입될 수 있는 오일공을 형성하여, 노면상태 및 운동상황에 따라 피스톤 하부의 오일을 피스톤 상부로 유입 또는 차단을 무단으로 비례제어 할 수 있게 하여 승차감 및 조정안정성을 극대화 시킬수 있도록 안출한 것으로서 이하 본 고안을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is to form an oil tube in the center of the piston and the piston rod installed in the cylinder in order to solve the conventional problems described above, the oil can be introduced into the piston upper side, road surface conditions and movement conditions Accordingly, the oil in the lower part of the piston is introduced to the upper part of the piston to control the steplessly proportionately to maximize the riding comfort and adjustment stability. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

실린더(2)와 외통(5)을 일체로 설치하고 실린더(2) 내부에 오일공(4)이 형성된 피스톤(3)을 설치하며 실린더(2)와 외통(5)의 하부에는 오일이 유동되어 감쇠력을 가변시킬 수 있도록 밸브스프링(7)을 설치한 내부에 오일(6)을 주입하여 된 쇽업소어보(1)에 있어서, 실린더(2)에 설치되고, 차체에 고정되는 피스톤(3)과 피스톤로드(8)의 중앙을 관통하게 오일관(9)을 형성하고, 피스톤(3) 상측의 피스톤로드(8) 일측단으로 피스톤(3) 하부의 오일(6)의 피스톤(3) 상부로 유입될 수 있는 오일공(10)을 형성한 후 이 오일공(10) 상측으로, 원하는 위치에서 비례적으로 제어할수 있는 솔레노이드(11)를 설치하되, 이솔레노이드(11)의 하측으로 상기 피스톤로드(8)에 형성된 오일공(10)를 비례적으로 미세하게 개폐할 수 있는 솔레노이드밸브(12)를 설치하였다.The cylinder 2 and the outer cylinder 5 are integrally installed, and the piston 3 having the oil ball 4 formed therein is installed inside the cylinder 2, and oil is flowed through the lower portion of the cylinder 2 and the outer cylinder 5. In the shock absorber (1) in which oil (6) is injected into the valve spring (7) in which the damping force can be varied, the piston (3) installed in the cylinder (2) and fixed to the vehicle body; An oil pipe 9 is formed to penetrate the center of the piston rod 8, and one end of the piston rod 8 on the upper side of the piston 3 is upward of the piston 3 of the oil 6 below the piston 3. After forming the oil hole 10 that can be introduced into the oil ball 10 above, install a solenoid 11 that can be proportionally controlled at a desired position, the piston rod to the lower side of the solenoid 11 The solenoid valve 12 which can open and close the oil hole 10 formed in (8) proportionally and minutely was installed.

이때, 실린더(2)내의 오일(6)은 피스톤로드(8)의 오일관(9)에 형성된 오일공(10)상측으로 오일공(10)을 개폐할 수 있도록 솔레노이드 밸브(12)가 설치되어 오일관(9) 상측으로는 오일(6)이 올라가지 못하게 되는 것이다.At this time, the oil 6 in the cylinder 2 is provided with a solenoid valve 12 to open and close the oil hole 10 above the oil hole 10 formed in the oil pipe 9 of the piston rod 8. The oil 6 is prevented from rising above the oil pipe 9.

그리고, 솔레노이드(11)는 ECU(Electronic controled Unit)(13)와 연결하고, 이 ECU(13)는 조향핸들각 브레이크, 차속, 캬브레이터 등의 신호를 감지할수 있는 센서부(14)와 연결하여서된 것이다.Then, the solenoid 11 is connected to the ECU (Electronic controled Unit) 13, the ECU 13 is connected to the sensor unit 14 that can detect signals such as steering wheel angle brake, vehicle speed, carburator, etc. will be.

이와 같이 구성된 본 고안은 차축과 차체에 속업소오버(1)를 설치하여, 자동차의 진동상태 즉, 조향핸들, 브레이크상태, 차속등의 신호를 센서부(14)에서 감지하면 이 신호를 ECU(Electronic controled Unit)(13)로 보내서 분삭한후 분석된 로직(LOGIC)에 따라, 피스톤로드(8)의 오일관(9)에 설치된 솔레노이드(11)가 작동하여 솔레노이드밸브(12)가 오일공(10)을 개폐시키는 것이다.According to the present invention configured as described above, when the sensor unit 14 detects a signal such as a steering state, a steering wheel, a brake state, a vehicle speed, and the like, by installing a fast overrun 1 on the axle and the vehicle body, the signal is detected by the ECU ( According to the analyzed logic (LOGIC), the solenoid 11 installed in the oil pipe 9 of the piston rod 8 is operated, and the solenoid valve 12 is operated by the oil ball (10). 10) to open and close.

이와 같이 작동되는 쇽업소버(1)는 약한충격에 의하여 피스톤(3)이 실린더(2)내에서 운동할 때에는 센서브(14)에서 충격을 감지하면 ECU(13)에서 분석한후 분석된 로직에 따라 솔레노이드(11)로 보낸다.The shock absorber 1 operated as described above is applied to the analyzed logic after analysis by the ECU 13 when the shock sensor 14 detects an impact when the piston 3 moves in the cylinder 2 due to a weak impact. To the solenoid (11).

그러면, 솔레노이드(11)가 피스톤로드(8)의 오일관(9)에 설치된 솔레노이드밸브(12)를 상측으로 올려서 피스톤로드(8)의 오일관(9)에 형성된 오일공(10)을 개방하게 되어 피스톤(3) 하부의 오일(6)이 피스톤(3) 상부로 오일관(9)과, 오일공(10)을 통하여 재빨리 유입되어 피스톤(3)이 상하로 부드럽게 운동하여 승차감이 좋게 되는 것이다. 이때 유량조절은 센서부(14)의 감지여하에 따라 작동되는 것이다.Then, the solenoid 11 raises the solenoid valve 12 installed in the oil pipe 9 of the piston rod 8 upwards to open the oil hole 10 formed in the oil pipe 9 of the piston rod 8. Thus, the oil 6 in the lower part of the piston 3 flows quickly through the oil pipe 9 and the oil hole 10 to the upper part of the piston 3 so that the piston 3 smoothly moves up and down to improve ride comfort. . At this time, the flow rate control is to operate according to the detection of the sensor unit 14.

또한 노면상태가 불균일한 경우 즉 피스톤(3)이 운동할때에는 센서부(14)에서 감지된 강한 충격을 ECU(13)에서 분석된 로직(LOGIC)을 피스톤로드(8)의 오일관(9)에 설치된 솔레노이드(11)로 보내면 이 솔레노이드밸브(12)를 하강시켜 오일관(9)에 형성된 오일공(10)을 차단하여 피스톤(3) 하부의 오일(6)과 상부의 오일(6)을 차단하게 되어 피스톤(3)이 힘을 받으면서 운동하게 되므로서 이 또한 승차감을 양호하게 하는 것이다.In addition, when the road surface is uneven, that is, when the piston 3 moves, the logic analyzed by the ECU 13 is transmitted to the oil pipe 9 of the piston rod 8 when the strong shock detected by the sensor unit 14 is moved. When it is sent to the installed solenoid 11, the solenoid valve 12 is lowered to block the oil hole 10 formed in the oil pipe 9 to block the oil 6 in the lower part of the piston 3 and the oil 6 in the upper part. The piston (3) is to move while being subjected to the force is also to improve the ride comfort.

이때, 유량조절은 센서부(14)의 감지여하에 따라 솔레노이드 밸브(12)가 승하강하면서 조절되는 것이다.At this time, the flow rate is adjusted while the solenoid valve 12 is raised and lowered according to the detection of the sensor unit 14.

그리고, 피스톤(13)이 승하강하면서 진동을 감쇠할때 센서부(14)에 감지된 신호를 ECU(13)에 보내서 ECU(13)에서 분석된 충격의 여하에 따라 피스톤(3)과 피스톤로드(8)에 형성된 오일관(9)의 솔레노이드밸브(12)가 오일공(10)을 무단으로 승하강 하면서 개폐조절할 수 있는 것이다.Then, when the piston 13 is raised and lowered, the piston 13 and the piston rod are sent to the ECU 13 by sending a signal sensed by the sensor unit 14 to damp the vibration. Solenoid valve 12 of the oil pipe (9) formed in (8) is to control the opening and closing while raising and lowering the oil hole 10 without permission.

이상 설명한 바와 같이 자동차에서 발생되는 모든 진동을 센서부에서 감지하여 ECU에서 분석한 후 분석된 로직에 따라, 피스톤과, 피스톤로드의 오일관에 설치된 솔레노이드의 솔레노이드밸브가 피스톤 상하부의 유량을 무단으로 조절하여 정밀한 제어를 하므로서 승차감 및 조정안정성을 극대화 시킬 수 있는 유용한 고안이다.As described above, all vibrations generated by the vehicle are detected by the sensor unit and analyzed by the ECU, and according to the analyzed logic, the solenoid valve of the solenoid installed in the oil pipe of the piston rod and the piston rod regulates the flow rate of the piston upper and lower endlessly It is a useful design that can maximize ride comfort and adjustment stability by precise control.
