The present invention relates to a rear shock absorber mounting structure capable of preventing the damping rubber from being melted by frictional heat and extending its life.
일반적으로, 자동차의 현가장치(suspension system)는 차축과 차체를 연결하여 주는 것으로, 주행 중에 차축이 노면에서 받는 진동이나 충격을 흡수하여 차체에 직접 전달되지 함으로써, 차체나 화물의 손상을 방지하고 승차감을 좋게 유지하는 장치로서, 차량의 뒤차축에는 도 1에 도시한 바와 같은 쇽 업소버가 장착된다.In general, the suspension system of a vehicle connects the axle and the body, and absorbs vibrations or shocks received from the road surface while the vehicle is not directly transmitted to the body, thereby preventing damage to the body or cargo and providing a comfortable ride. As a device for maintaining a good quality, the shock absorber as shown in FIG. 1 is mounted on the rear axle of the vehicle.
도 1은 종래의 리어 쇽 업소버의 장착구조를 보인 단면도이다 종래의 쇽 업소버의 장착구조를 보면, 쇽 업소버(8)의 하부를 구성하는 하부 스트럿(6)은 부시(4)를 개재하여 로어 컨트롤 아암에 부착된 브라켓(2)에 고정되며, 상단은 상부 댐핑고무(16)와 하부 댐핑고무(18)를 개재하여 차체(12)에 고정된다. 이들 댐핑고무(16), (18)는 상부 플레이트(15)와 하부 플레이트(14)에 의해 감싸져 있으며, 상부 플레이트(15)상에는 너트(22)를 체결한 다음, 부트(20)를 조립한다1 is a cross-sectional view showing a mounting structure of a conventional shock absorber. In the conventional mounting structure of a shock absorber, the lower strut 6 constituting the lower portion of the shock absorber 8 is provided with a lower control via a bush 4. It is fixed to the bracket (2) attached to the arm, the upper end is fixed to the vehicle body (12) via the upper damping rubber 16 and the lower damping rubber (18). These damping rubbers 16 and 18 are surrounded by the upper plate 15 and the lower plate 14, and the nut 22 is fastened on the upper plate 15, and then the boot 20 is assembled.
이러한 구성을 지닌 종래의 리어 쇽 업소버 장착구조에서는 장시간 운행시에 상부 댐핑고무와 하부 댐핑고무가 쇽 업소버의 피스톤 로드와 반복적으로 마찰 접촉함으로써, 이때 발생되는 마찰열에 의해 용융되어 댐핑효과가 저감되는 문제가 있다.In the conventional rear shock absorber mounting structure having such a configuration, the upper damping rubber and the lower damping rubber repeatedly frictionally contact the piston rod of the shock absorber during long time operation, thereby causing the damping effect to be reduced due to the frictional heat generated. There is.
이와 같은 문제점을 해결하기 위해 안출된 본 발명은 쇽 업소버의 피스톤 로드에 2개의 스페이서를 끼운 다음에, 상부 댐핑고무와 하부 댐핑고무를 장착함으로써, 마찰열에 의해 댐핑고무가 용융되는 것을 방지하여 수명을 연장할 수 있는 리어 쇽 업소버 장착구조를 제공하는데 그 목적이 있다.The present invention devised to solve such a problem is to fit the two spacers to the piston rod of the shock absorber, and then by mounting the upper damping rubber and the lower damping rubber, to prevent the damping rubber from melting by frictional heat to extend the life Its purpose is to provide an extensible rear shock absorber mounting structure.

상술한 본 발명의 목적은 노면으로부터 전달되는 진동이나 충격을 흡수하기 위한 코일 스프링의 진동을 흡수하는 차량의 리어 쇽 업소버에 있어서, 쇽 업소버의 피스톤 로드의 외측면에 밀착되는 하부 스페이서와, 하단은 하부 스페이서의 외측면에 끼워지며 상단에는 상부 플레이트가 배치되는 상부 스페이서와, 하부 플레이트에 배치되며 하부 쇽 업소버를 감싸고 있는 하부 댐핑고무와, 차체를 사이에 두고 하부 댐핑고무와 대향으로 배치되며 상부 스페이서를 감싸고 있는 상부 댐핑고무와, 상부 플레이트에 배치되는 피스톤 로드에 체결되는 너트로 이루어진 것을 특징으로 하는 리어 쇽 업소버 장착구조에 의해서 달성된다.The above object of the present invention is a rear shock absorber of a vehicle that absorbs vibrations of a coil spring for absorbing vibrations or shocks transmitted from a road surface, the lower spacer being in close contact with the outer surface of the piston rod of the shock absorber, The upper spacer is fitted to the outer surface of the lower spacer and the upper plate is disposed on the upper side, the lower damping rubber disposed on the lower plate and surrounding the lower shock absorber, and disposed opposite to the lower damping rubber with the vehicle body interposed therebetween. It is achieved by a rear shock absorber mounting structure, characterized in that the upper damping rubber surrounding the, and the nut is fastened to the piston rod disposed on the upper plate.
본 발명에 의하면, 2개의 스페이서에 의해 댐핑고무와 쇽 업소버의 스트럿과의 직접적인 마찰을 방지함으로써, 댐핑고무의 수명을 연장하여 댐핑효과를 증대시킬 수 있는 이점이 있다.According to the present invention, the two spacers prevent the direct friction between the damping rubber and the strut of the shock absorber, thereby extending the life of the damping rubber and increasing the damping effect.
이하, 첨부한 도 2를 참조하여 본 발명의 바람직한 실시예에 따른 리어 쇽 업소버 장착구조에 대하여 상세히 설명한다.Hereinafter, a rear shock absorber mounting structure according to a preferred embodiment of the present invention with reference to the accompanying Figure 2 will be described in detail.
도 2는 본 발명에 따른 리어 쇽 업소버 장착구조를 보인 단면도로, 도 1에서 설명한 구조와 동일한 부품은 동일한 부호로 표시하여 설명한다.Figure 2 is a cross-sectional view showing a rear shock absorber mounting structure according to the present invention, the same parts as the structure described in Figure 1 will be described with the same reference numerals.
노면으로부터 전달되는 진동이나 충격을 흡수하기 위한 코일 스프링의 진동을 최대한 빨리 억제하여 진동을 감쇠하는 본 발명에 따른 리어 쇽 업소버(8) 장착구조에서는 쇽 업소버(8)의 피스톤 로드(10)와 댐핑고무(34), (36)간의 직접적인 마찰을 피하기 위하여 이들 댐핑고무(34), (36)내에 2개의 스페이서(spacer)(38), (40)를 끼워 넣었다.In the rear shock absorber 8 mounting structure according to the present invention, which suppresses the vibration of the coil spring for absorbing the vibration or shock transmitted from the road surface as soon as possible, damping the piston rod 10 of the shock absorber 8 and damping. In order to avoid direct friction between the rubbers 34 and 36, two spacers 38 and 40 are inserted in these damping rubbers 34 and 36.
보다 상세히 살펴보면, 쇽 업소버(8)의 피스톤 로드(10)의 외측면에는 하부 스페이서(38)를 끼운 다음, 이 하부 스페이서(38)의 외측면에는 상부 스페이서(40)를 끼웠으며, 하부 스페이서(38)와 상부 스페이서(40)의 외측면에는 각각, 하부 댐핑고무(34)와 상부 댐핑고무(36)를 배치하였다.In more detail, the lower spacer 38 is fitted to the outer surface of the piston rod 10 of the shock absorber 8, and then the upper spacer 40 is fitted to the outer surface of the lower spacer 38. 38 and the lower damping rubber 34 and the upper damping rubber 36 are disposed on the outer surfaces of the upper spacer 40 and the upper spacer 40, respectively.
여기에서, 하부 댐핑고무(34)는 하부 플레이트(30)에 의해 쇽 업소버(8)의 스트럿 상에 배치하여, 하부 댐핑고무(34)와 상부 댐핑고무(36)간에는 차체(12)가 배치된다. 또한, 상부 댐핑고무(36)상에는 상부 플레이트(32)가 배치되며, 상부 플레이트(32)를 관통하여 설치되는 피스톤 로드(10)에는 너트(22)를 체결하여 결합하였다. 하부 댐핑고무(34)의 하단에는 돌출단(34a)이 형성되어 있어, 상부 댐핑고무(36)의 하단에 형성된 홈내에 삽입되도록 하였다.Here, the lower damping rubber 34 is disposed on the strut of the shock absorber 8 by the lower plate 30, so that the vehicle body 12 is disposed between the lower damping rubber 34 and the upper damping rubber 36. . In addition, an upper plate 32 is disposed on the upper damping rubber 36, and a nut 22 is coupled to the piston rod 10 installed through the upper plate 32. Protruding end 34a is formed at the lower end of the lower damping rubber 34 to be inserted into the groove formed at the lower end of the upper damping rubber 36.
이러한 구성을 지닌 본 발명의 쇽 업소버에 있어서, 노면으로부터 충격이 전달되어 범핑(bumping)될 경우, 하부 댐핑고무(34)가 압축되면서 하부 스페이서(38)를 상승시킴으로써, 하부 스페이서(38)는 상부 스페이서(40)내로 압입된다. 반대로, 리바운딩(rebounding)시에는 상부 댐핑고무(36)가 압축되면서 상부 스페이서(40)는 하부 스페이서(38)의 외측면을 따라 하강함으로써, 쇽 업소버(8)의 피스톤 로드(10)와 댐핑고무(34), (36)간의 직접적인 마찰을 피할 수 있게 된다.In the shock absorber of the present invention having such a configuration, when the shock is transmitted from the road surface and bumped, the lower spacer 38 is raised by raising the lower spacer 38 while the lower damping rubber 34 is compressed. It is press fit into the spacer 40. On the contrary, during the rebounding, the upper damping rubber 36 is compressed while the upper spacer 40 is lowered along the outer surface of the lower spacer 38, whereby the piston rod 10 and the damping rubber of the shock absorber 8 are dampened. Direct friction between (34) and (36) can be avoided.
이상으로 설명한 본 발명에 따른 리어 쇽 업소버 장착구조는 2개의 스페이서에 의해 댐핑고무와 쇽 업소버의 스트럿과의 직접적인 마찰을 방지함으로써, 댐핑고무의 수명을 연장하여 댐핑효과를 증대시킬 수 있는 효과를 갖는다.The rear shock absorber mounting structure according to the present invention described above has the effect of increasing the damping effect by extending the life of the damping rubber by preventing the direct friction between the damping rubber and the strut of the shock absorber by two spacers. .
