쇽업소버는 노면으로부터 주행중인 차량의 차체로 전해지는 진동을 억제, 감쇄하는 역할을 하며, 특히 차체의 상하 방향 진동에너지를 흡수함으로써, 승차감 향상, 적재화물의 보호, 그리고, 차량의 각 부품을 보호하는데 기여한다.The shock absorber serves to suppress and attenuate the vibration transmitted from the road surface to the vehicle body of the vehicle being driven, and in particular, by absorbing the up and down vibration energy of the vehicle body, improving the riding comfort, protecting the loaded cargo, and protecting each part of the vehicle. Contributes to

쇽업소버는 통상, 실린더와, 그 실린더 내에 슬라이드 가능하게 수용되는 피스톤 및 이 피스톤에 연결된 채 실린더 외부로 연장되는 피스톤 로드를 포함한다. 이러한 종래의 쇽업소버가 차량에 설치될 때, 일반적으로 실린더는 차축 또는 차륜 측에 고정되고 피스톤로드는 차체 측에 고정된다.The shock absorber typically includes a cylinder, a piston slidably received within the cylinder, and a piston rod extending out of the cylinder while being connected to the piston. When such a conventional shock absorber is installed in a vehicle, the cylinder is generally fixed to the axle or wheel side and the piston rod is fixed to the vehicle body side.

쇽업소버는 차량이 노면을 주행할 때 연속적으로 압축(compression) 행정과 리바운드(rebound) 행정을 반복하면서 노면에서 차체로 전해지는 진동 및 충격을 감쇠, 완화하는 기능을 수행할 수 있다.The shock absorber may function to attenuate and mitigate vibrations and shocks transmitted from the road surface to the vehicle body while repeatedly compressing and rebounding the road when the vehicle travels on the road surface.

도 1에는 종래기술에 따른 쇽업소버의 일례를 도시한 단면도가 도시되어 있다. 도 1에 도시된 바와 같이, 종래의 쇽업소버는, 실린더(1)와, 이 실린더(1) 내 에서 직선이동함으로써 감쇠력을 발생시키는 피스톤(2) 및 피스톤 로드(3)와, 피스톤(2)의 상부에 부착되어 피스톤(2)이 실린더(1)의 상단과 충돌하는 것을 방지하는 스토퍼(4)를 가진다.1 is a cross-sectional view showing an example of a shock absorber according to the prior art. As shown in FIG. 1, the conventional shock absorber includes a cylinder 1, a piston 2 and a piston rod 3 generating a damping force by linearly moving in the cylinder 1, and a piston 2. It has a stopper 4 attached to the top of the to prevent the piston 2 from colliding with the top of the cylinder 1.

그런데, 쇽업소버의 리바운드 행정시 피스톤(2)을 보호하기 위해 부착된 스토퍼(4)가 실린더(1)의 상단에 순간적으로 접촉하면서 둔탁한 소음과 진동을 발생시키는 경우가 있었다.By the way, the stopper 4 attached in order to protect the piston 2 at the time of the rebound stroke of the shock absorber may generate dull noise and vibration while instantaneously contacting the upper end of the cylinder 1.

본 발명은 이러한 종래의 문제점들을 해결하기 위한 것으로서, 본 발명의 목적은, 쇽업소버의 리바운드 작동시 피스톤 로드에 부착된 스토퍼가 실린더 상단과 충돌하면서 발생하는 소음과 진동을 저감시킬 수 있도록 피스톤 로드에 설치되는 완충장치를 가지는 쇽업소버를 제공하고자 하는 것이다.SUMMARY OF THE INVENTION The present invention has been made to solve these conventional problems, and an object of the present invention is to provide a piston rod with a stopper attached to the piston rod during the rebound operation of the shock absorber to reduce the noise and vibration generated by collision with the upper end of the cylinder.

상기 완충장치는, 상기 완충부재와 상기 실린더의 내주면 사이에 개재되는 지지 링 부재를 더 포함하는 것이 바람직하다.Preferably, the shock absorber further includes a support ring member interposed between the shock absorbing member and the inner circumferential surface of the cylinder.

상기 지지 링 부재는, 외주면이 상기 실린더의 내주면과 밀착될 수 있도록 원통형상을 가지는 동시에 내주면은 상기 완충부재의 몸체와 동일한 정다각형을 가지며, 상기 지지 링 부재의 내주면에는 상기 완충부재의 날개부가 각각 맞닿아 있는 것이 바람직하다.The support ring member has a cylindrical shape such that the outer circumferential surface may be in close contact with the inner circumferential surface of the cylinder, and the inner circumferential surface has the same regular polygon as the body of the shock absorbing member. It is desirable to touch.

또한, 상기 완충장치는 상기 실린더 상단 부분을 이루는 로드 가이드의 하부면에 설치되는 것이 바람직하다.In addition, the shock absorber is preferably installed on the lower surface of the rod guide forming the upper portion of the cylinder.

이하, 본 발명의 바람직한 실시예에 따른 쇽업소버의 소음 감소용 완충장치를 도면을 참조하여 상세하게 설명한다.Hereinafter, a shock absorber for reducing noise of a shock absorber according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 2에는 본 발명에 따른 소음 감소용 완충장치가 설치된 쇽업소버의 일례가 도시되어 있고, 도 3에는 상기 완충장치에 포함되는 완충부재가 전개된 상태를 나타내는 도면이 도시되어 있다. 도 4에는 상기 완충부재를 만곡시킨 상태를 나타내는 도면이 도시되어 있고, 도 5에는 만곡시킨 상태의 상기 완충부재와 지지 링 부재가 결합된 상태를 나타내는 도면이 도시되어 있다.2 shows an example of a shock absorber provided with a shock absorber for reducing noise according to the present invention, and FIG. 3 shows a state in which a shock absorber included in the shock absorber is deployed. 4 is a view showing a state in which the buffer member is curved, and FIG. 5 is a view showing a state in which the buffer member and the support ring member are coupled in a curved state.

도 2에 도시된 바와 같이, 본 발명에 따른 소음 감소용 완충장치를 가지는 쇽업소버는, 종래와 마찬가지로, 쇽업소버의 외형을 형성하는 실린더(1)와, 이 실린더(1) 내에서 직선이동함으로써 감쇠력을 발생시키는 피스톤(2) 및 피스톤 로드(3)와, 피스톤(2)의 상부에 부착되어 피스톤(2)이 실린더(1)의 상단과 충돌하는 것을 방지하는 스토퍼(4)를 가진다.As shown in Fig. 2, the shock absorber having the shock absorber for reducing noise according to the present invention is, as in the prior art, by a linear movement in the cylinder 1 and the cylinder 1 forming the outer shape of the shock absorber. It has a piston (2) and a piston rod (3) for generating a damping force, and a stopper (4) attached to the upper portion of the piston (2) to prevent the piston (2) from colliding with the upper end of the cylinder (1).

다만, 본 발명에 따르면, 스토퍼(4)와 실린더(1) 상단과의 사이의 피스톤 로드(3)에 충돌시 소음 및 진동을 감소시키기 위한 완충장치가 설치된다. 구체적으로는, 상기 완충장치는 실린더(1) 상단 부분의 하부면, 즉 로드 가이드의 하부면에 설치되는 것이 바람직하다.According to the present invention, however, a shock absorber for reducing noise and vibration in the event of a collision is installed in the piston rod 3 between the stopper 4 and the upper end of the cylinder 1. Specifically, the shock absorber is preferably provided on the lower surface of the upper end of the cylinder 1, that is, the lower surface of the rod guide.

본 발명에 따른 상기 완충장치는 도 1 및 도 2에 도시된 형태의 쇽업소버 이외에 모노 튜브식(mono tube type) 쇽업소버나 듀얼 튜브식(dual tube type) 쇽업소버 등 다른 모든 형태의 쇽업소버에도 장착될 수 있음은 물론이다.The shock absorber according to the present invention may be mounted on all other types of shock absorbers such as a mono tube type shock absorber or a dual tube type shock absorber in addition to the shock absorbers of the type shown in FIGS. 1 and 2. Of course it can.

상기 완충장치는, 도 3 내지 도 5에 도시된 바와 같이, 탄성을 가지는 완충부재(10)로 이루어진다. 또한 본 발명에 따르면, 이 완충부재(10)를 실린더(1) 내에서 지지하는 지지 링 부재(20)를 더 포함하는 것이 바람직하다.The shock absorber, as shown in Figures 3 to 5, consists of a buffer member 10 having elasticity. In addition, according to the present invention, it is preferable to further include a support ring member 20 for supporting the buffer member 10 in the cylinder (1).

도 3에 도시된 바와 같이, 상기 완충부재(10)는, 중심부분에 피스톤 로드(3)가 삽입되는 관통구멍(12)을 가지는 다각형상 몸체(11)와, 이 몸체(11)의 외측 가장자리를 따라서 배열되는 날개부(13)를 포함하여 이루어진다.As shown in FIG. 3, the shock absorbing member 10 has a polygonal body 11 having a through hole 12 into which a piston rod 3 is inserted into a central portion thereof, and an outer edge of the body 11. It comprises a wing 13 arranged along the.

상기 몸체(11)는 도면에는 육각형으로 도시되어 있지만, 육각형만으로 한정되는 것은 아니며 필요에 따라 다양한 다각형상으로 변형될 수 있다. 이때, 실린더(1)의 내부에 배치되는 상기 몸체(11)는 후술하는 바와 같이 힘을 실린더(1)의 내주면 측으로 균등하게 전달할 수 있도록 정육각형, 정팔각형 등과 같이 정다각형을 가지는 것이 바람직하다.Although the body 11 is illustrated in the figure as a hexagon, it is not limited to the hexagon alone and may be transformed into various polygonal shapes as necessary. At this time, it is preferable that the body 11 disposed inside the cylinder 1 has a regular polygon such as a regular hexagon, a regular octagon, and the like so as to transmit force to the inner circumferential surface side of the cylinder 1 as described below.

상기 날개부(13)는 말단 부분이 대략 타원형으로 둥글게 형성되며, 도 4에 도시된 바와 같이 만곡될 수 있도록 가요성을 가지는 것이 바람직하다.The wing 13 has a distal end that is round in an elliptical shape, and preferably has flexibility to be curved as shown in FIG. 4.

상기 날개부(13)는 만곡되어 탄성을 가지도록 형성되어 있으므로, 쇽업소버가 최대로 신장되어 도 2에 도시된 바와 같이 피스톤 로드(3)에 부착된 스토퍼(4)가 상기 완충장치와 맞닿으면, 상기 날개부(13)가 변형되면서 피스톤 로드(3)의 축선방향으로 전달되는 힘을 반경방향으로 분산시킨다. 이와 같이 축선방향 힘을 반경방향으로 분산시킴으로써 차체 측으로 충격이 전달되는 것을 막아 진동 발생을 억제할 수 있다.Since the wing portion 13 is formed to be bent and elastic, the shock absorber is extended to the maximum and the stopper 4 attached to the piston rod 3 as shown in FIG. 2 is in contact with the shock absorber. When the wing 13 is deformed, the force transmitted in the axial direction of the piston rod 3 is distributed in the radial direction. By dispersing the axial force in the radial direction as described above, it is possible to prevent the shock from being transmitted to the vehicle body side and to suppress the occurrence of vibration.

또한, 상기 날개부(13)는 충격이 가해지면 즉시 변형을 일으키므로, 스토퍼(4)와 날개부(13)는 순간적으로 접촉되는 것이 아니라 접촉하는 시간이 길어지게 된다. 따라서 스토퍼(4)와 날개부(13)가 접촉함으로써 발생하는 충격이 순간적으로 집중되지 않고 분산되어 차체 측으로 전달되는 충격과 진동이 현저하게 감소될 수 있다.In addition, since the wing 13 is immediately deformed when an impact is applied, the stopper 4 and the wing 13 are not instantaneously contacted, but the contact time becomes long. Therefore, the shock and vibration transmitted by the stopper 4 and the wing 13 in contact with the vehicle body side, rather than being concentrated instantaneously, can be significantly reduced.

본 발명에 따르면, 도 5에 도시된 바와 같이, 상기 완충부재(10)와 실린더(1)의 내주면 사이에 상기 지지 링 부재(20)가 개재되는 것이 바람직하다.According to the invention, as shown in Figure 5, it is preferable that the support ring member 20 is interposed between the buffer member 10 and the inner peripheral surface of the cylinder (1).

상기 지지 링 부재(20)는, 외주면이 실린더(1)의 내주면과 밀착될 수 있도록 원통형상을 가지며, 내주면은 완충부재(10)의 몸체(11)와 동일한 다각형상을 가진다. 다각형상의 내주면에는 각각 날개부(13)가 맞닿아 있다.The support ring member 20 has a cylindrical shape such that the outer circumferential surface may be in close contact with the inner circumferential surface of the cylinder 1, and the inner circumferential surface has the same polygonal shape as the body 11 of the buffer member 10. The wing part 13 abuts on the polygonal inner peripheral surface, respectively.

본 발명에 따르면, 상기 지지 링 부재(20)가 완충부재(10)와 실린더(1) 내주면과의 사이에 배치되어 있기 때문에, 완충부재(10)가 실린더(1) 내주면에 직접 접촉할 경우 야기될 수 있는 완충부재(10)의 변형 혹은 실린더(1) 내주면의 손상을 방지할 수 있으며, 완충부재(10)로부터 실린더(1)의 내주면 측으로 전달되는 힘을 원활하게 전달하여 분산시킬 수 있다.According to the present invention, since the support ring member 20 is disposed between the buffer member 10 and the inner circumferential surface of the cylinder 1, this occurs when the buffer member 10 is in direct contact with the inner circumferential surface of the cylinder 1. Deformation of the shock absorbing member 10 or damage to the inner circumferential surface of the cylinder 1 may be prevented, and the force transmitted from the shock absorbing member 10 to the inner circumferential surface side of the cylinder 1 may be smoothly transmitted and distributed.

이상과 같이 본 발명에 따른 쇽업소버의 완충장치를, 예시된 도면을 참조하여 설명하였으나, 본 발명은 이상에서 설명된 실시예와 도면에 의해 한정되지 않으며, 특허청구범위 내에서 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자들에 의해 다양한 수정 및 변형이 이루어질 수 있음은 물론이다.As described above, the shock absorber of the shock absorber according to the present invention has been described with reference to the illustrated drawings, but the present invention is not limited to the embodiments and drawings described above, and the present invention belongs to the claims. Of course, various modifications and variations can be made by those skilled in the art.
