본 발명은 쇽 업소버를 개시한다.The present invention discloses a shock absorber.
본 발명은 외통 실린더와 내통 실린더로 이루어지며, 피스톤 로드 및 피스톤 밸브를 구비한 쇽 업소버에 있어서, 외통 실린더의 일단에 확관부를 형성하여 외통 실린더와 내통 실린더의 간섭을 억제하는 것을 특징으로 한다.The invention consists of an outer cylinder and an inner cylinder, and in a shock absorber having a piston rod and a piston valve, an expansion pipe is formed at one end of the outer cylinder to suppress interference between the outer cylinder and the inner cylinder.
Description
본 발명은 쇽 업소버에 관한 것으로, 더욱 상세하게는 외통 실린더의 일단에 확관부를 형성하여 외통 실린더와 내통 실린더의 간섭을 억제할 수 있는 쇽 업소버에 관한 것이다.The present invention relates to a shock absorber, and more particularly, to a shock absorber capable of suppressing interference between an outer cylinder and an inner cylinder by forming an expansion pipe at one end of the outer cylinder.
현가장치는 주로 차체와 차축 사이에 설치되어 주행 중 노면으로부터 전달되는 충격이나 진동을 완화시켜 바퀴와 노면의 점착성을 향상시키고 승차감을 양호하게 해주는 장치이다.Suspension device is mainly installed between the vehicle body and the axle to reduce the shock or vibration transmitted from the road surface while driving to improve the adhesion between the wheel and the road surface and to improve the riding comfort.
특히, 쇽 업소버(shock absorber)는 노면에서 발생한 스프링의 자유진동을흡수하여 승차감을 향상시키는 것으로, 스프링이 압축될 때에는 급격히 압축되고 늘어날 때는 오일의 저항력을 크게 하며 서서히 작동함으로서 스프링의 상하운동 에너지를 열에너지로 변환시키는 일을 한다.In particular, the shock absorber absorbs the free vibration of the spring generated on the road surface and improves the riding comfort. When the spring is compressed, it is rapidly compressed and increases the resistance of the oil when it is increased and gradually operates to increase the up and down kinetic energy of the spring. It converts into heat energy.
이와 같은 쇽 업소버의 일 예가 도 1에 도시되어 있다.An example of such a shock absorber is shown in FIG. 1.
도 1에 도시된 바와 같이, 쇽 업소버는 안내를 겸한 길고 가는 외통 실린더(1)와 내통 실린더(2)의 조합으로 구성되어 있고, 내통 실린더(2)는 차축과 연결되며, 외통 실린더(1)는 피스톤 로드(3)와 함께 차체에 연결된다. 피스톤 로드(2)의 말단에는 피스톤 밸브(4)가 설치되어 있으며, 내통 실린더(1)에는 오일이 가득 채워져 있다. 피스톤 밸브(4)에는 오일이 통과하는 오리피스(5)가 형성되어 있다.As shown in Fig. 1, the shock absorber is composed of a combination of a long and thin outer cylinder 1 and an inner cylinder 2 serving as a guide, and the inner cylinder 2 is connected to the axle, and the outer cylinder 1 Is connected to the vehicle body together with the piston rod 3. The piston valve 4 is attached to the end of the piston rod 2, and the inner cylinder cylinder 1 is filled with oil. The piston valve 4 is formed with an orifice 5 through which oil passes.
피스톤 밸브(4)는 실린더의 압축운동시 피스톤 밸브(4)의 아래쪽에 저장된 튜브내의 오일이 오리피스(5)를 통해 반대편 튜브(압축 챔버)로 유출된다. 이때, 피스톤 로드(3)의 압축운동에 대한 감쇠력이 발생된다.The piston valve 4 flows oil in the tube stored below the piston valve 4 through the orifice 5 into the opposite tube (compression chamber) during the compression movement of the cylinder. At this time, the damping force with respect to the compression movement of the piston rod (3) is generated.
한편, 실린더(1)의 신장 운동시 피스톤 밸브(4)의 위쪽에 저장된 튜브내의 오일이 오리피스(5)를 통해 반대편 튜브(신장 챔버)로 유출된다. 이때 피스톤 로드(3)의 신장운동에 대한 감쇠력이 발생된다.On the other hand, in the extension movement of the cylinder 1, the oil in the tube stored above the piston valve 4 flows out through the orifice 5 to the opposite tube (extension chamber). At this time, a damping force with respect to the stretching movement of the piston rod 3 is generated.
그런데 이와 같은 종래의 쇽 업소버는 외통 실린더(1)와 외통 실린더(2)의 간격이 작아 신장 또는 압축 시 외통 실린더(1)에 의해 내통 실린더(2)의 외경부가 긁히거나 이로 인해 소음이 발생될 수 있다. 특히, 쇽 업소버의 장착 각도가 커지는 경우 이와 같은 현상이 심화된다.However, such a conventional shock absorber has a small gap between the outer cylinder 1 and the outer cylinder 2 so that the outer diameter of the inner cylinder 2 may be scratched by the outer cylinder 1 during expansion or compression, or noise may be generated. Can be. In particular, such a phenomenon is exacerbated when the mounting angle of the shock absorber becomes large.
따라서 본 발명은 이와 같은 종래의 문제점을 해결하기 위한 것으로, 외통 실린더와 내통 실린더의 간섭을 억제하여 소음 및 이로 인한 감쇠기능의 저하를 방지하기 위한 쇽 업소버를 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a shock absorber for suppressing the interference between the outer cylinder and the inner cylinder cylinder to prevent noise and deterioration of the damping function.
이와같은 목적을 실현하기 위한 본 발명은 외통 실린더와 내통 실린더로 이루어지며, 피스톤 로드 및 피스톤 밸브를 구비한 쇽 업소버에 있어서, 외통 실린더의 일단에 확관부를 형성하여 외통 실린더와 내통 실린더의 간섭을 억제하는 것을 특징으로 한다.The present invention for achieving the above object is composed of an outer cylinder and an inner cylinder, in a shock absorber having a piston rod and a piston valve, by forming an expansion pipe at one end of the outer cylinder to prevent interference between the outer cylinder and the inner cylinder. It is characterized by suppressing.
본 발명의 목적과 여러 가지 장점은 이 기술 분야에 숙련된 사람들에 의해 첨부된 도면을 참조하여 아래에 기술되는 발명의 바람직한 실시예로부터 더욱 명확하게 될 것이다.The objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

이하, 첨부된 도면을 참조하여 본 발명의 일실시예를 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the present invention.
도 2는 본 발명에 따른 확관부가 형성된 쇽 업소버를 도시한 정단면도이며, 종래와 동일한 구성부재에 대해서는 동일한 도면부호를 부여하여 설명한다.Fig. 2 is a front sectional view showing a shock absorber having an expansion pipe according to the present invention, and the same components as in the prior art will be described with the same reference numerals.
도시된 바와 같이, 본 발명에 따른 쇽 업소버는 안내를 겸한 길고 가는 외통 실린더(1)와 내통 실린더(2)의 조합으로 구성되어 있고, 내통 실린더(2)는 차축과 연결되며, 외통 실린더(1)는 피스톤 로드(3)와 함께 차체에 연결된다. 피스톤 로드(2)의 말단에는 피스톤 밸브(4)가 설치되어 있으며, 내통 실린더(1)에는 오일이 가득 채워져 있다. 피스톤 밸브(4)에는 오일이 통과하는 오리피스(5)가 형성되어 있다.As shown, the shock absorber according to the present invention is composed of a combination of a long and thin outer cylinder 1 and an inner cylinder 2 serving as a guide, and the inner cylinder 2 is connected to the axle, and the outer cylinder 1 Is connected to the vehicle body together with the piston rod 3. The piston valve 4 is attached to the end of the piston rod 2, and the inner cylinder cylinder 1 is filled with oil. The piston valve 4 is formed with an orifice 5 through which oil passes.
특히, 본 발명의 특징적인 구성에 따르면, 외통 실린더(1)의 일단에 확관부(10)가 형성되어 외통 실린더(1)와 내통 실린더(2)의 간격이 종래의 구조에 비해 넓게 형성됨을 알 수 있다. 이와 같은 확관부(10)는 외통 실린더(1) 상부의 구조는 변경시키지 않으므로 종래의 다른 부품들을 변경없이 그대로 적용할 수 있다.In particular, according to the characteristic configuration of the present invention, it is understood that the expansion tube 10 is formed at one end of the outer cylinder cylinder 1 so that the distance between the outer cylinder cylinder 1 and the inner cylinder cylinder 2 is wider than that of the conventional structure. Can be. Since the expansion part 10 does not change the structure of the upper portion of the outer cylinder 1, other conventional parts may be applied as it is without modification.
한편, 예시도면에서는 외통 실린더(1)에 확관부(10)가 일체로 형성되는 것을 보이고 있으나, 2단 조립식으로도 변경할 수 있다.On the other hand, in the exemplary drawing, it is shown that the expansion pipe 10 is integrally formed in the outer cylinder 1, but can be changed to a two-stage assembly type.
이와 같은 본 발명에 따른 확관부를 구비한 쇽 업소버는 쇽 업소버의 장착각도가 측 방향으로 기울어진 경우에도 외통 실린더(1)와 내통 실린더(2) 사이의 간격이 넓어 간섭이 일어나지 않아 긁힘이나 이로 인한 소음이 발생되지 않는다. 또한, 차량 주행 중 내통 실린더(2)에서 발생된 열이 원활하게 방열될 수 있으므로 쇽 업소버의 내구성 및 성능 향상에도 큰 역할을 한다.The shock absorber having an expansion tube according to the present invention has a wide gap between the outer cylinder 1 and the inner cylinder 2 even when the mounting angle of the shock absorber is inclined laterally, so that no interference occurs, so that the shock absorber No noise is generated. In addition, since the heat generated in the inner cylinder 2 can be smoothly dissipated while the vehicle is running, it also plays a big role in improving the durability and performance of the shock absorber.
이상, 상기 내용은 본 발명의 바람직한 일 실시예를 단지 예시한 것으로 본 발명의 당업자는 본 발명의 요지를 변경시킴이 없이 본 발명에 대한 수정 및 변경을 가할 수 있음을 인지해야 한다.In the foregoing description, it should be understood that those skilled in the art can make modifications and changes to the present invention without changing the gist of the present invention as merely illustrative of a preferred embodiment of the present invention.
상술한 바와 같이 본 발명에 따르면, 외통 실린더와 내통 실린더의 간섭을 억제하여 소음 및 이로 인한 감쇠기능의 저하를 방지할 수 있다.According to the present invention as described above, it is possible to suppress the interference between the outer cylinder and the inner cylinder cylinder to prevent noise and deterioration of the damping function.
