As shown therein, the conventional shock absorber 1 has an inner tube 20 filled with oil, an outer tube 10 filled with oil to the outside thereof, and one end is inserted into the inner tube 20. The other end is provided with a piston rod 30 extending to the outside of the outer tube (10).
상기 내부관(20)은 외부관(10)의 내측에 외부관(10)과 소정간격 이격되도록 설치되어 그 사이에 오일이 저장되는 저장실(15)을 형성하는 중공관으로서, 상측은 피스톤 로드(30)가 외부로 연장될 수 있도록 그 중심축이 개구되어 있고, 그 하측에는 저장실(15)과 내부관(20)의 내부로 오일이 유동되는 바디 몸체(22)를 가진 바디 밸브(21)가 설치되며, 그 하부에 발판(40)과 외부관(10)에 베이스 캡(50)이 압입 설치된다. 그리고 내부관(20)의 내부에는 내부관(20)과 마찰되면서 슬라이딩 이동되는 피스톤 밸브(31)가 설치된다.The inner tube 20 is a hollow tube installed inside the outer tube 10 to be spaced apart from the outer tube 10 by a predetermined interval to form a storage chamber 15 in which oil is stored therebetween, the upper side of which is a piston rod ( A central valve is opened so that 30 may extend outward, and a lower side body valve 21 having a body body 22 through which oil flows into the storage chamber 15 and the inner tube 20 is provided. The base cap 50 is press-fitted to the footrest 40 and the outer tube 10 at the bottom thereof. And the inside of the inner tube 20 is provided with a piston valve 31 which is slid and moved friction with the inner tube (20).
여기서 바디밸브(21)는 바디몸체(22)에 통로(23)가 관통한 상태로 복수 형성된다.Here, the body valve 21 is formed in plural in a state where the passage 23 penetrates the body body 22.
그리고 바디몸체(22)의 상면에는 스프링(24)이 설치되고, 바디몸체(22)의 하면에는 통로(23)를 개폐시키는 다판 디스크(25)가 설치된다.And a spring 24 is provided on the upper surface of the body body 22, the multi-plate disk 25 for opening and closing the passage 23 is provided on the lower surface of the body body 22.
그리고 다판 디스크(25)는 순차적으로 적층되는 복수의 디스크(26)와, 디스크-S(27)와, 상기 발판(40)과 바디몸체(22)와의 수평 상태를 유지하기 위한 디스크링(28)으로 이루어지며, 디스크-S(27)에는 외측으로 개방된 슬릿(27a)이 다수개 형성된다.And the multi-disc disk 25 is a plurality of disks 26 are sequentially stacked, disk-S (27), the disk ring 28 for maintaining the horizontal state of the footrest 40 and the body body 22 The disk-S 27 is formed with a plurality of slits 27a opened outward.
이와 같이 구성된 쇽 업소버의 바디밸브(21)는 피스톤 로드(30)의 상하 왕복운동에 따라 내부관(20)과 외부관(10)에 채워진 오일이, 저속에서는 바디밸브(21)의 외측을 따라 디스크-S(27)의 슬릿(27a)을 통과하여 감쇠력을 발생시키며, 고속에서는 통로(23)를 통과하면서 감쇠력이 발생하게 된다.The body valve 21 of the shock absorber configured as described above is oil filled in the inner tube 20 and the outer tube 10 according to the vertical reciprocating motion of the piston rod 30, and at a low speed along the outer side of the body valve 21. The damping force is generated by passing through the slit 27a of the disk-S 27, and the damping force is generated while passing through the passage 23 at high speed.
그러나 이렇게 바디밸브를 통과하는 오일이 저속과 고속에서 다르게 유로가 형성됨으로써, 산포가 발생하게 된다. 따라서 감쇠력의 성능 저하를 가져오는 단점이 있었다.However, as the oil passing through the body valve is formed differently at low speed and high speed, dispersion occurs. Therefore, there was a disadvantage that the performance of the damping force.

이하 첨부된 도면을 참조하여 본 발명에 따른 바람직한 실시 예를 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명에 따른 쇽 업소버의 바디밸브의 단면도이다.2 is a cross-sectional view of the body valve of the shock absorber according to the present invention.
도 2에 도시되어 있는 바와 같이, 내부관(200) 하단 발판(300)의 상부에 설치되는 바디밸브(210)는 바디몸체(220)에 통로(230)가 관통한 상태로 복수개 형성된다.As shown in FIG. 2, a plurality of body valves 210 installed on an upper portion of the lower foot plate 300 of the inner tube 200 are formed in a state in which passages 230 penetrate through the body body 220.
그리고 바디몸체(220)의 상면에는 스프링(240)이 설치되고, 바디몸체(220)의 하면에는 통로(230)를 개폐시키는 다판 디스크(250)가 설치된다.And a spring 240 is installed on the upper surface of the body body 220, the multi-plate disk 250 for opening and closing the passage 230 is installed on the lower surface of the body body 220.
여기서 본 발명에 따라 다판 디스크(250)는 순차적으로 적층되는 디스크-S(252)와, 복수개의 디스크(254)로 구성된다.According to the present invention, the multi-plate disc 250 is composed of a disk-S 252 and a plurality of disks 254 sequentially stacked.
디스크-S(252)에 형성되는 슬릿(252a)은 개방면이 내측을 향하도록 원주방향으로 다수개 형성된다.A plurality of slits 252a formed in the disk-S 252 are formed in the circumferential direction so that the open surface faces inward.
그리고 복수개의 디스크(254)는 디스크-S(252)와 발판(300)에 사이에 설치되어, 통로(230)를 따라 감쇠력을 발생시킬 뿐만 아니라, 상기 발판(300)의 원형부에 거치되는 바디몸체(220)의 수평 상태를 유지하도록 하는 기능이 추가된다.The plurality of disks 254 are installed between the disk-S 252 and the scaffold 300 to generate a damping force along the passage 230, as well as a body mounted on the circular portion of the scaffold 300. The function of maintaining the horizontal state of the body 220 is added.
이와 같이 구성된 본 발명에 쇽 업소버의 바디밸브의 작동을 설명하면 다음과 같다.Referring to the operation of the shock absorber body valve in the present invention configured as described above are as follows.
먼저, 인장 행정시의 저속과 고속구간에서는 도 2에 도시된 바와 같이, 유체가 바디몸체(220)의 통로(230)를 통해 스프링(240)을 상방으로 압축하면서 감쇠력을 발생시키게 된다.First, in the low speed and high speed sections during the tension stroke, as shown in FIG. 2, the fluid generates the damping force while compressing the spring 240 upward through the passage 230 of the body body 220.
그리고 압축 행정시의 저속과 고속구간에서는 도 2의 실선으로 도시된 바와 같이, 유체가 통로(230)로 유입되고, 유입된 유체는 다판 디스크(250)중 디스크-S(252)의 내측면에 형성된 슬릿(252a)과 디스크(254)를 통과하면서 감쇠력을 발생시키게 된다.In the low speed and high speed sections of the compression stroke, as shown by the solid line of FIG. 2, the fluid flows into the passage 230, and the fluid flows into the inner surface of the disc-S 252 in the multi-plate disc 250. The damping force is generated while passing through the formed slit 252a and the disk 254.
이와 같이 다판 디스크(250)의 구성을 내측면에 슬릿(252a)이 형성된 디스크-S(252)를 먼저 적층 시킴으로서, 저속에서나 고속구간에서의 유체 흐름이 통로(230)를 통하여 다판 디스크(250)의 내측으로 일정하게 유입된다.Thus, by stacking the disk-S 252 in which the slits 252a are formed on the inner surface of the multi-layer disk 250, the fluid flow in the low speed or the high-speed section is transmitted through the passage 230. It is constantly introduced into the inside of.
따라서 항상 일정한 유로로 흐르는 유체는 산포의 발생이 줄어들게 되어 감쇠력 성능이 좋아진다.Therefore, the fluid always flowing in a constant flow path will reduce the occurrence of scattering and the damping force performance is improved.
또한, 종래에 발판(300)의 상부에 설치되어 수평 상태를 유지하던 디스크 링의 삭제로 원가절감을 이루게 된다.In addition, the cost reduction is achieved by eliminating the disk ring, which is conventionally installed on the top of the scaffold 300 to maintain a horizontal state.
이상에서는 본 발명을 특정의 바람직한 실시 예에 대하여 도시하고 또한 설명하였으나, 본 발명은 상술한 실시 예에 한정되지 아니하며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 이하 청구범위에 기재된 본 발명의 요지를 벗어남이 없이 다양한 변경실시가 가능할 것이다.Although the present invention has been illustrated and described with respect to certain preferred embodiments, the present invention is not limited to the above-described embodiments, and a person skilled in the art to which the present invention pertains has the present invention set forth in the claims below. Various modifications may be made without departing from the spirit of the invention.
이상에서 설명한 바와 같이 본 발명의 쇽 업소버의 바디밸브는, 바디밸브를 통과하는 오일이 일정한 유로를 가질 수 있도록 바디밸브의 구조를 개선함으로써, 유체의 산포 현상이 줄어들어 감쇠력 성능이 향상되는 효과가 있다.As described above, the body valve of the shock absorber of the present invention improves the structure of the body valve so that the oil passing through the body valve has a certain flow path, thereby reducing the dispersion of fluid and improving the damping force performance. .
또한, 디스크 링의 삭제로 원가절감을 이루는 효과가 있다.In addition, there is an effect of reducing the cost by eliminating the disk ring.
