본 고안은 자동차의 (승용차, 상용차)의 진동을 감쇠시키기 위한 전기 유압식 쇽업소오버에 관한 것으로, 특히 쇽업소오버내의 유량을 노면상태에 따라 조절하여 간쇠력을 무단변환시켜 승차감 및 조정안정성을 극대화시키고져 한 것이다.The present invention relates to an electro-hydraulic shock absorber for damping vibration of a car (commercial car, commercial vehicle). In particular, the flow rate within the shock absorber is adjusted according to the road surface condition to maximize the riding comfort and adjustment stability. I was supposed to.
주지된 바와 같이 쇽업소오버는 자동차가 주행할때 스프링에 받는 충격에 의해 발생하는 고유진동을 흡수하여 진동을 빨리 감쇠시켜 승차감을 좋게 하기 위해 설치하는 것으로서 일반적으로 유압식을 주로 사용하여 진동을 감쇠하였다.As is well known, shock absorbers are installed to absorb the natural vibrations caused by the impact of the spring when the car is running and to attenuate the vibrations quickly to improve ride comfort. .
그런데 종래에는 제2도에 도시한 바와 같이 쇽업소오버(21)가 차축쪽과 연결하는 실린더(22)와 차체쪽으로 연결하는 피스톤(23)이 결합되어 있고 실린더(22) 내부에는 오일(26)이 채워져 있다.However, in the related art, as shown in FIG. 2, a cylinder 22 connecting the shock absorber 21 to the axle side and a piston 23 connecting to the vehicle body are coupled, and the oil 26 inside the cylinder 22. Is filled.
그리고 피스톤(23)이 상하운동할때 오일(26)이 통과할수 있도록 오일공(24)이 형성되고 실린더(22) 외부에는 감쇠력을 가변시킬수 있는 외통(25)을 형성한후 실린더(22) 내부의 오일(26)이 외통(25)으로 통과할수 있도록 실린더(22)위 하부에 밸브스프링(27)을 설치하여 구성된 것이다.When the piston 23 moves up and down, the oil hole 24 is formed to allow the oil 26 to pass therethrough, and the outer cylinder 25 is formed outside the cylinder 22 to vary the damping force. The valve 26 is installed on the lower portion of the cylinder 22 so that the oil 26 can pass through the outer cylinder 25.
이와 같이 구성된 쇽업소오버(22)는 단순히 실린더(21)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 유동되면서 자동차가 주행할때 차측쪽에서 발생되는 진동을 감쇠시켰는 바, 이는 노면상태 및 운동상황에 따라 크고, 적은 상태인 2단의 감쇠력과, 크고, 보통, 적은 상태인 3단의 감쇠력만 조정가능하여 각단에서의 감쇠력차이가 서로 커서 모오드(MODE) 변환시 승차자의 승차감이 나쁘며 순간적으로 조종안정성을 잃어버릴 수 있는 문제점이 있었다.The shock absorber 22 configured as described above simply moves the oil 21 inside the cylinder 21 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. As the oil 26 flows through the installed valve spring 27, the vibration generated from the vehicle side is attenuated when the vehicle is running, which is large and small depending on road conditions and movement conditions, and the damping force of the second stage is large and large. In general, only a small amount of damping force in three stages is adjustable, so that the difference in damping force in each stage is large, resulting in a poor riding comfort of the rider during mode conversion and a loss of steering stability.
본 고안은 상기한 종래의 문제점을 해결하기 위하여 외통의 외측으로 오일통을 형성하되 이 오일통을 관통하여 외통과, 오일이 통과될수 있는 오일관을 형성한후 이 오일관의 내부에 비례제어할수 있는 솔레노이드밸브를 설치한 상태로 오일관을 오일통의 하측과 관통연결하여 노면의 상태 및 운동상황에 따라 오일관의 내부에 설치된 솔레노이드밸브가 미세한 감쇠력을 비례제어조정할 수 있게하여 승차감 및 조정안정성을 극대화할수 있도록 안출한 것으로서 이하 본 고안을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention forms an oil barrel on the outside of the outer cylinder in order to solve the above-mentioned conventional problems, and can be controlled proportionally to the inside of the oil tube after forming the outer tube and the oil tube through which the oil can pass. With the solenoid valve installed, the oil pipe is connected with the lower part of the oil tank so that the solenoid valve installed inside the oil pipe can adjust the fine damping force proportionally by the condition of the road surface and the movement situation. When the present invention is described in detail by the accompanying drawings as designed to maximize as follows.
실린더(2)의 내부에 오일공(4)이 형성된 피스톤(3)을 설치하며 실린더(2) 외부에 감쇠력을 가변시킬 수 있는 외통(5)을 형성하되 실린더(2) 하부에 밸브스프링(13)을 설치하여 실린더(2) 내부 및 외통(5) 내부에 오일(6)을 주입하여서된 쇽업소오버(1)에 있어서, 외통(6)의 외측으로 오일통(7)을 형성하되 오일통(7)을 관통되게 외통(6)에 오일관(8)을 관통설치한후, 이 오일관(8)의 끝단은 오일통(7)의 하측부와 관통되게 연결하였다.Install a piston (3) having an oil hole (4) formed inside the cylinder (2) and form an outer cylinder (5) for varying the damping force on the outside of the cylinder (2), but the valve spring (13) under the cylinder (2) In the shock absorber (1) in which the oil (6) is injected into the cylinder (2) and the inside of the outer cylinder (5), the oil barrel (7) is formed outside the outer cylinder (6). After the oil pipe 8 was penetrated to the outer cylinder 6 so as to penetrate (7), the end of the oil pipe 8 was connected to penetrate the lower side of the oil barrel 7.
이때 오일관(8)의 통로에는 오일을 비례제어할수 있는 솔레노이드밸브(10)를 오일관외측에 설치한 솔레노이드(9)와 연결설치하는 한편 이 솔레노이드(9)는 ECU(Electronic controled Unit)(11)와 연결하고, 이 ECU(13)는 조향핸들각, 브레이크 차속, 캬브레이터 등의 신호를 감지할 수 있는 센서부(12)와 연결하여서된 것이다.At this time, a solenoid valve 10 capable of proportionally controlling oil is connected to and installed in the passage of the oil pipe 8 with a solenoid 9 installed outside the oil pipe, and the solenoid 9 is an ECU (Electronic controled unit) 11. The ECU 13 is connected to a sensor unit 12 capable of detecting a signal such as a steering wheel angle, a brake vehicle speed, a carburetor, and the like.
이와 같이 구성된 본 고안은 차체쪽과 차체쪽에 속업소오버(1)를 설치하여 자동차의 진동상태, 즉 조향핸들각, 브레이크상태, 차속등의 신호를 센서부(12)에서 감지하여 이 신호를 ECU(11)에서 분석한후 ECU(11)와 연결된 솔레노이드(9)를 작동하여 솔레노이드(9)를 작동하여 솔레노이드(9)에 설치된 솔레노이드밸브(10)가 승하강하면서 오일(8)의 통로를 미세하게 조정할 수 있는 것이다.According to the present invention configured as described above, the business unit (1) is installed on the vehicle body side and the vehicle body side to detect a vibration state of the vehicle, that is, a steering wheel angle, a brake state, a vehicle speed, and the like in the sensor unit 12 to detect the ECU. After analyzing in (11), the solenoid (9) connected to the ECU (11) is operated to operate the solenoid (9) to move up and down the solenoid valve (10) installed in the solenoid (9) while the passage of the oil (8) is fine. Can be adjusted.
이와 같이 작동되는 쇽업소버(1)에 강한 충격이 가해지면 이 강한충격을 센서부(12)에서 감지하여 센서부(12)에서 감지된 신호를 ECU(11)로 도달하면 ECU(11)에서 분석된 충격을 솔레노이드밸브(10)가 충격여하에 따라 무단으로 하강하여 오일관(8)을 막으면서 조절함으로써 강한 충격제어에도 승차감이 부드럽게 되고 한편 충격이 약할때에도 이 충격을 센서부(12)에서 감지하여 그 신호를 ECU(11)로 보내면 ECU(11)에서 분석된 충격을 솔레노이드(9)로 보내 솔레노이드(9)가 솔레노이드밸브(10)를 충격의 여하에 따라 미세하게 작동하여 오일관(8)을 무단으로 상하유동되면서 조절하는 것이다.When a strong shock is applied to the shock absorber 1 operated as described above, the strong shock is detected by the sensor unit 12, and when the signal detected by the sensor unit 12 reaches the ECU 11, the ECU 11 analyzes the signal. As the solenoid valve 10 descends according to the impact of the shock, the shock is lowered to prevent the oil pipe 8 from being adjusted. Thus, even in the strong impact control, the riding comfort is smooth and the shock is detected by the sensor unit 12 even when the impact is weak. When the signal is transmitted to the ECU 11, the shock analyzed by the ECU 11 is sent to the solenoid 9, so that the solenoid 9 operates the solenoid valve 10 finely according to the impact and the oil pipe 8 It is to adjust the flow without permission.
이상 설명한 바와 같이 자동차에서 발생되는 모든 진동을 센서부에서 감지하여 쇽업소오버내의 유량을 노면상태 및 운동상황에 따라 무단으로 조정하여 정밀한 제어를 함으로써 승차감 및 조정안정성을 극화시킬수 있는 유용한 고안이다.As described above, all vibrations generated in the vehicle are sensed by the sensor unit, and the flow rate in the shop-over is adjusted in an unauthorized manner according to the road surface conditions and motion conditions, thereby making it possible to minimize ride comfort and adjustment stability.
