본 고안은 자동차의 새시 스프링에 발생하는 진동을 흡수하기 위하여 바디와 프레임 사이에 설치하는 쇽업쇼버에 관한 것으로, 특히 상용차등에 장착되어 하중이 과다하게 부과되면 낮은 차고에서 큰 감쇄력을 얻으며, 부하 제거시 상대적으로 높은 차고에서 낮은 감쇄력을 얻을 수 있는 스트로크 감응식 쇽업쇼버에 관한 것이다.The present invention relates to a shock absorber installed between the body and the frame in order to absorb the vibration generated in the chassis spring of the car, especially when it is mounted on a commercial vehicle such that excessive load is applied to obtain a large damping force in a low garage, when removing the load A stroke-sensitive shock absorber capable of achieving low damping at a relatively high garage.
자동차 진동을 단시간에 흡수하기 위하여 바디와 샤시사이에 설치하는 스트로크 감응식 쇽업쇼버(10)의 튜브(12)내에는 피스톤(18)과 디스크(17) 그리고, 리테이너(16)등이 설치된 구성을 이루었고, 튜브(12)의 내부를 상실(13)과 하실(14)로 구분하는 리테이너(16)에는 중앙에 유체의 이동을 위한 통공(16a)이 뚫려 있는 바, 상기한 리테이너(16)의 통공(16a)과 피스톤(18)의 오일통과부분(18a)이 일치되었을 때, 오일이 이동하게 되는 것이다.In the tube 12 of the stroke-sensitive shock absorber 10 provided between the body and the chassis to absorb the vehicle vibration in a short time, the piston 18, the disk 17, and the retainer 16 are installed. The retainer 16, which divides the inside of the tube 12 into the upper chamber 13 and the lower chamber 14, has a through hole 16a for moving the fluid in the center thereof, and the through hole of the retainer 16. When the oil passing portion 18a of 16a and the piston 18 coincide, the oil moves.
그리고 이러한 종래의 리테이너(16)는 그 외주연의 끝단이 튜브(12)의 내벽에 형성된 나선형 슬라이드홀(15)을 따라 이동하기 때문에 승강운동을 하면서 회전운동을 병행한다.And the conventional retainer 16 is the end of the outer periphery moves along the helical slide hole 15 formed on the inner wall of the tube 12, so as to move in parallel with the rotational movement.
이와 같이 승강운동과 함께 회전운동이 발생하면 제 2 도에서와 같이 유체 이동을 위한 다수의 통공(16a)들이 불연속적으로 형성되어 있기 때문에 각각의 통공(16a)이 피스톤의 오일 통과부분(18a)과 일치하는 시간외에는 유체의 흐름이 순간적으로 차단되고, 따라서 유체 흐름에 순간적으로 저항이 증대되어 급격히 감쇄력이 증가하며, 리테이너(16)가 계속 회전할 경우 다시 좀 더 큰 홀에 유로가 접하게 되어 감쇄력은 다시 감소한다.As such, when the rotary motion occurs along with the lifting and lowering motions, the plurality of through holes 16a are discontinuously formed as shown in FIG. Outside the time coinciding with, the flow of the fluid is momentarily interrupted, so the resistance to the fluid flow is instantaneously increased so that the damping force increases rapidly, and when the retainer 16 continues to rotate, the flow path is brought into contact with the larger hole again. Decreases again.
즉, 기존의 스트로크 감응식 쇽업쇼버는 작동위치별로 다른 감쇄력을 발생시킬 수 있지만 감쇄력의 불연속점이 발생하여 쇽업쇼버로서의 기능을 제 3 도에서와 같이 상실하게 된다.That is, the conventional stroke-sensitive shock absorber can generate different damping force for each operating position, but discontinuities of the damping force occur, thus losing the function as the shock absorber as shown in FIG.
본 고안은 이러한 문제점을 해결하기 위하여 감쇄력이 안정적으로 발생하는 홀을 제공하고자 하는 것으로, 이를 첨부도면과 함께 설명하면 다음과 같다.The present invention is to provide a hole in which a damping force is generated stably in order to solve this problem, described with the accompanying drawings as follows.
자동차의 진동을 흡수하기 위해 튜브(2)속에 유체를 충진하고, 이 튜브 속으로 로드(19)가 연결된 피스톤(8)을 삽입하여 피스톤의 이동시 피스톤에 뚫린 오리피스(8a)와 디스크(7), 리테이너(6)등을 거치는 유체의 저항에 의하여 감쇄력을 발생시키는 통상의 쇽업쇼버(1)를 형성함에 있어서, 상기의 튜브(2) 내경에 형성된 슬라이드홀(5)에 끼워지는 리테이너 표면에 유체의 이동을 위해 유체홀(6a)을 형성하되, 유체홀(6a)을 지나는 유체의 저항이 연속적인 변화를 이루도록 중앙을 제외한 둘레면을 태극형상으로 뚫어 형성한다.Filling the fluid into the tube (2) to absorb the vibration of the vehicle, and inserts the piston (8) connected to the rod 19 into the tube, the orifice (8a) and the disk (7) drilled in the piston during the movement of the piston, In forming a conventional shock absorber 1 which generates a damping force by the resistance of a fluid passing through a retainer 6 or the like, the fluid is deposited on the retainer surface fitted in the slide hole 5 formed in the inner diameter of the tube 2. A fluid hole 6a is formed for movement, and a periphery except for the center is formed in a taiji shape so that the resistance of the fluid passing through the fluid hole 6a forms a continuous change.
상기의 구성으로 이루어진 본 고안은 리테이너가 회전함에 따라 유체홀(6a)이 연속적으로 변화하는 형상으로 이루어져 있기 때문에, 제 2 도에서 보는 바와 같이 유체가 유체홀(6a)을 통과할 때 통공사이의 막히는 부분이 없어지게 되고, 따라서 급격한 감쇄력의 증가가 없어지게 되는 것이다.Since the present invention having the above configuration has a shape in which the fluid hole 6a is continuously changed as the retainer rotates, as shown in FIG. 2, when the fluid passes through the fluid hole 6a, There is no blockage, so there is no sudden increase in damping power.
이처럼 유체의 흐름이 원활해지면 진동위치에 일정한 피스톤의 속도에서도 작동위치에 따라 서로 다른 감쇄력을 발생시킬 수 있게 된다.As the fluid flows smoothly, different damping forces can be generated depending on the operating position even at a constant piston speed in the vibration position.
이상에서와 같이 본 고안은 리테이너에 일정한 간격으로 홀이 구성되어 있어 작동 위치에 따라 서로 다른 감쇄력을 낼 수 있는 단점이었던 감쇄력의 불연속 점을 개선하여 연속적인 감쇄력을 얻을 수 있는 이점이 있는 것이다.As described above, the present invention has an advantage in that the holes are formed at regular intervals in the retainer, thereby improving the discontinuity of the damping force, which was a disadvantage in that different damping forces can be produced depending on the operating position.
