상술한 목적을 달성하기 위해, 본 발명에 따른 쇼크업소버는 오리피스에 의해 상부챔버와 하부챔버로 구획된 오일챔버를 구비한 어퍼튜브, 어퍼튜브의 상부챔버 상단에 설치되는 에어챔버, 하부챔버 측면의 일정 높이에 설치되어 오일탱크와 연통된 오일튜브, 어퍼튜브의 하부챔버에 삽입되도록 설치되는 피스톤을 구비한 로워 피스톤, 및 어퍼튜브와 로워 피스톤 사이에 설치되는 스프링으로 구성되어, 엔진의 진동은 스프링으로 완충하고, 노면진동은 유체와 기체를 이용하여 완충하는 것을 특징으로 한다.In order to achieve the above object, the shock absorber according to the present invention is an upper tube having an oil chamber partitioned into an upper chamber and a lower chamber by an orifice, an air chamber installed on top of an upper chamber of an upper tube, and a lower chamber side. It consists of an oil tube installed at a certain height and communicating with the oil tank, a lower piston having a piston installed to be inserted into the lower chamber of the upper tube, and a spring installed between the upper tube and the lower piston. To buffer, road vibration is characterized in that the buffer using a fluid and gas.
이하, 첨부 도면을 참조하여, 본 발명에 따른 쇼크업소버의 일 실시예의 구성에 대해 설명한다.Hereinafter, with reference to the accompanying drawings, a configuration of an embodiment of a shock absorber according to the present invention will be described.
도 1에 본 발명에 따른 쇼크업소버의 단면도가 도시되어 있다.1 is a cross-sectional view of the shock absorber according to the present invention.
도시된 바와 같이, 본 발명에 따른 쇼크업소버는 유압, 공기압 및 스프링을 혼합한 형태의 쇼크업소버를 제공한다.As shown, the shock absorber according to the present invention provides a shock absorber of a mixture of hydraulic, pneumatic and spring.
즉, 본 발명에 따른 쇼크업소버는 어퍼 튜브(10)의 상부에 에어챔버(12)가 설치되고, 에어챔버(12)의 하부에는 작동유체가 내장되는 오일챔버(15)가 형성되며, 오일챔버(15)는 오리피스(16)에 의해 상부챔버(17)와 하부챔버(18)로 분할되어 있다.That is, in the shock absorber according to the present invention, the air chamber 12 is installed at the upper portion of the upper tube 10, and the oil chamber 15 is formed at the lower portion of the air chamber 12 in which a working fluid is built in. 15 is divided into an upper chamber 17 and a lower chamber 18 by an orifice 16.
또한, 오일챔버(15)의 외측에는 스프링(25)을 설치하기 위한 환형의 홈(19)이 길이방향을 따라 형성되어 있다.Moreover, the outer side of the oil chamber 15 is formed with the annular groove 19 for installing the spring 25 along the longitudinal direction.
또한, 에어챔버(12)내의 가스를 보충하기 위해 어퍼튜브(10)를 관통하여 에어챔버(12)와 연통된 필러밸브(13)를 설치한다.In addition, a filler valve 13 is installed through the upper tube 10 to communicate with the air chamber 12 so as to replenish gas in the air chamber 12.
한편, 어퍼튜브(10)에 감합되는 로워 피스톤(20)은 중앙에 피스톤(21)이 형성되며 피스톤(21)의 주위에 환형의 홈(22)이 형성되어 홈(22)의 외측에는 어퍼튜브(10)의 환형홈(19)에 감합되는 돌기(23)가 형성된다.Meanwhile, the lower piston 20 fitted to the upper tube 10 has a piston 21 formed at the center thereof, and an annular groove 22 is formed around the piston 21 to form an upper tube outside the groove 22. A projection 23 fitted into the annular groove 19 of 10 is formed.
또한, 어퍼튜브(10)의 환형홈(19)과 로워 피스톤(20)의 환형홈(22) 사이에는 압축스프링(25)이 설치된다.In addition, a compression spring 25 is installed between the annular groove 19 of the upper tube 10 and the annular groove 22 of the lower piston 20.
한편, 어퍼튜브(10)의 하부 챔버(18)의 일측으로는 작동오일 탱크(도시하지 않음)와 연통된 오일튜브(30)가 설치된다. 오일튜브(30)의 설치높이는 엔진의 진동폭을 감안하여 엔진의 최대진동폭과 일치하도록 설정하는 것이 중요하다.On the other hand, one side of the lower chamber 18 of the upper tube 10 is provided with an oil tube 30 in communication with the operating oil tank (not shown). It is important to set the installation height of the oil tube 30 to match the maximum vibration width of the engine in consideration of the vibration width of the engine.
따라서, 본 발명에 따른 쇼크업소버는 엔진의 진동역내에서는, 도 2에 도시한 바와 같이, 최대 진동시 로워 피스톤(20)의 상승높이가 오일튜브(30)의 하부에 위치하므로 하부챔버(18)내의 작동오일은 오일튜브(30)를 통해 오일탱크로 이동하게 되어, 엔진에 의한 진동은 어퍼튜브(10)와 로워 피스톤(20) 사이에 설치된 압축스프링(25)으로 흡수하게 된다.Accordingly, in the shock absorber according to the present invention, as shown in FIG. 2, the lower height of the lower piston 20 is located at the lower part of the oil tube 30 at the maximum vibration, as shown in FIG. 2. The working oil in the inside is moved to the oil tank through the oil tube 30, the vibration by the engine is absorbed by the compression spring 25 installed between the upper tube 10 and the lower piston (20).
한편, 주행중 노면과 차륜사이에서 발생하는 노면진동은 엔진의 주기적 진동에 비해 진폭이 크며, 이 때 로워 피스톤(20)은, 도 3에 도시한 바와 같이, 오일튜브(30)의 설치높이를 지나 하부챔버(18)의 상부로 이동하게 되므로 하부챔버(18)내의 작동유는 오리피스(16)를 통해 상부챔버(17)로 이동하며 유체마찰에 의한 완충작용이 이루어지며, 또한, 상부챔버(17)로 이동한 작동유는 상부의 에어챔버(12)를 압축하여 기체압축에 따른 완충효과도 작용하여 노면으로부터의 진동을 흡수하게 된다.On the other hand, the road vibration generated between the road surface and the wheel while driving is larger in amplitude than the periodic vibration of the engine, and the lower piston 20 passes through the installation height of the oil tube 30, as shown in FIG. Since it moves to the upper portion of the lower chamber 18, the hydraulic fluid in the lower chamber 18 moves to the upper chamber 17 through the orifice 16, and the buffering action by the fluid friction is made, and the upper chamber 17 The working oil moved to compresses the upper air chamber 12 to act as a buffer effect according to gas compression, thereby absorbing vibration from the road surface.
상술한 바와 같이 구성된 본 발명에 따른 쇼크업소버를 사용하므로써, 주행중 차량에서 발생하는 엔진진동은 물론 노면으로부터의 진동까지 넓은 진동역에 걸친 진동을 흡수할 수 있으므로 쇼크업소버의 완충효율을 향상시킬 수 있게 된다.By using the shock absorber according to the present invention configured as described above, it is possible to absorb the vibration over a wide vibration range from the engine vibration generated in the vehicle while driving, as well as vibration from the road surface, thereby improving the buffering efficiency of the shock absorber. do.
이상에서 본 발명은 실시예를 통해 상세히 설명하였으나 본 발명은 이에 한정되는 것은 아니며 당해분야의 통상의 지식을 가진자라면 본 발명의 기술적 사상을 바탕으로 다양한 변형이나 수정이 가능할 것이며, 그러한 변경이나 수정은 다음의 청구범위에 포함되는 것이다.The present invention has been described in detail through the embodiments, but the present invention is not limited thereto, and those skilled in the art may make various changes or modifications based on the technical idea of the present invention.
