Description

차량용 쇽 업소버 장착구조Vehicle shock absorber mounting structure

본 발명은 차량용 쇽 업소버 장착구조에 관한 것으로, 보다 상세하게는 쇽 업소버의 피스톤 로드에 장착되는 스토퍼를 범퍼 러버 시트와 일체로 구성함으로써 이음을 방지할 수 있는 차량용 쇽 업소버 장착구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle shock absorber mounting structure, and more particularly, to a vehicle shock absorber mounting structure in which a stopper mounted on a piston rod of a shock absorber is integrally formed with a bumper rubber seat.

일반적으로, 자동차의 현가장치(suspension system)는 차축과 차체를 연결하여 주는 것으로, 주행 중에 차축이 노면에서 받는 진동이나 충격을 흡수하여 차체에 직접 전달되지 않게 함으로써, 차체나 화물의 손상을 방지하고 승차감을 좋게 유지하는 장치이다. 이러한 현가장치에는 노면에서 받는 충격을 완화시키는 코일 스프링과, 코일 스프링의 자유진동을 최대한 빨리 억제하여 승차감을 향상시키는 쇽 업소버(shock absorber)가 있다.In general, the suspension system of the vehicle connects the axle to the body, and prevents damage to the body or cargo by absorbing vibrations or shocks received from the road surface while the vehicle is not directly transmitted to the body. It is a device that maintains a good ride comfort. Such a suspension system includes a coil spring that mitigates the impact on the road surface and a shock absorber that suppresses free vibration of the coil spring as soon as possible to improve ride comfort.

도 1은 종래의 차량용 쇽 업소버 장착구조를 보인 단면도로, 쇽 업소버(2)의 상단에는 피스톤 로드(6)가 인출 가능하게 장착되어 있다. 피스톤 로드(6)의 외주부에는 댐핑 러버(8)가 끼워져 있으며, 댐핑 러버(8)상에는 러버 시트(10)가 배치된다. 또한, 러버 시트(10)의 상부에는 외측 브라켓(14)이 장착되며 외측 브라켓(14)내에는 마운팅 러버(16)가 끼워져 있다. 피스톤 로드(6)의 상단은 너트(18)에 의해 차체(4)에 고정된다. 외측 브라켓(14)의 하부에는 스토퍼(12)가 부착되어 있다.1 is a cross-sectional view showing a conventional shock absorber mounting structure for a vehicle. A piston rod 6 is mounted on the upper end of the shock absorber 2 so as to be pulled out. A damping rubber 8 is fitted to the outer circumferential portion of the piston rod 6, and a rubber seat 10 is disposed on the damping rubber 8. In addition, an outer bracket 14 is mounted on the upper portion of the rubber seat 10, and a mounting rubber 16 is fitted in the outer bracket 14. The upper end of the piston rod 6 is fixed to the vehicle body 4 by a nut 18. A stopper 12 is attached to the lower portion of the outer bracket 14.

이러한 구성을 지닌 종래의 차량용 쇽 업소버 장착구조에서는 쇽 업소버의 작동시에 스토퍼가 외측 브라켓과 접촉하면서 스토퍼로부터 이음이 발생하게 되어 승차감을 저하시키는 문제가 있다.In the conventional vehicle shock absorber mounting structure having such a configuration, when the shock absorber is operated, the stopper comes into contact with the outer bracket to generate a noise from the stopper, thereby reducing the riding comfort.

이와 같은 문제점을 해결하기 위해 안출한 본 발명은 스토퍼를 러버 시트와 일체로 구성하여 댐핑시의 이음을 최소화할 수 있는 차량용 쇽 업소버 장착구조를 제공하는 데 그 목적이 있다.The present invention devised to solve such a problem is to provide a shock absorber mounting structure for a vehicle that can minimize the joint at the time of damping by configuring the stopper integrally with the rubber seat.

상술한 본 발명의 목적은 쇽 업소버의 상부로부터 인출 가능하게 장착되는 피스톤 로드와, 피스톤 로드의 외주부에 끼워지는 댐핑 러버와, 마운팅 러버를 개재하여 피스톤 로드의 상단에 배치되는 외측 브라켓으로 구성되는 차량용 쇽 업소버 장착구조에 있어서, 댐핑 러버상에는 러버 시트가 배치되며, 러버 시트상에는 돌기를 지닌 스토퍼가 일체로 형성된 것을 특징으로 하는 차량용 쇽 업소버 장착구조에 의해 달성된다.The object of the present invention described above is for a vehicle composed of a piston rod that is releasably mounted from an upper portion of a shock absorber, a damping rubber fitted to an outer circumference of the piston rod, and an outer bracket disposed at an upper end of the piston rod via a mounting rubber. In the shock absorber mounting structure, a rubber seat is disposed on the damping rubber, and the stopper having protrusions is formed integrally on the rubber seat.

본 발명에 의하면, 스토퍼가 러버 시트와 일체로 구성되어 있기 때문에 쇽 업소버의 댐핑시에 스토퍼가 외측 브라켓과 접촉되어도 이음이 발생기지 않기 때문에 정숙성을 향상시킬 수 있는 이점이 있다.According to the present invention, since the stopper is integrally formed with the rubber seat, there is an advantage that the quietness can be improved because no noise is generated even when the stopper contacts the outer bracket during damping of the shock absorber.

이하, 첨부한 도 2를 참조하여 본 발명의 바람직한 실시예에 따른 차량용 쇽 업소버 장착구조에 대하여 상세히 설명한다.Hereinafter, a vehicle 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 발명의 차량용 쇽 업소버 장착구조를 보인 단면도로, 도 1에서 설명한 종래의 구조와 동일 부품은 동일 부호로 표시하여 설명한다.Figure 2 is a cross-sectional view showing a vehicle shock absorber mounting structure of the present invention, the same parts as the conventional structure described in Figure 1 will be described with the same reference numerals.

본 발명의 바람직한 실시예에 따른 쇽 업소버 장착구조에서는 외측 브라켓(14)과 접촉되는 스토퍼(20)로부터 발생되는 이음을 최소화하기 위해 스토퍼(20)를 댐핑 러버(8)상에 배치되는 러버 시트(10)와 일체로 형성하였다.In the shock absorber mounting structure according to the preferred embodiment of the present invention, the rubber seat is disposed on the damping rubber 8 so as to minimize the noise generated from the stopper 20 in contact with the outer bracket 14. It was formed integrally with 10).

이것의 전체적인 구성을 보면, 쇽 업소버(2)의 상부로부터 인출 가능하게 장착되는 피스톤 로드(6)와, 이 피스톤 로드(6)의 외주부에 끼워지는 댐핑 러버(8)와, 마운팅 러버(16)를 개재하여 피스톤 로드(6)의 상단에 배치되는 외측 브라켓(14)과, 상기 댐핑 러버(8)와 외측 브라켓(14)사이에 배치되는 것으로 스토퍼(20)가 일체로 형성된 러버 시트(10)로 이루어져 있다.In view of its overall configuration, a piston rod 6 mounted to be pulled out from the top of the shock absorber 2, a damping rubber 8 fitted to the outer circumference of the piston rod 6, and a mounting rubber 16 are shown. The rubber seat 10 in which the stopper 20 is integrally formed by being disposed between the outer bracket 14 and the damping rubber 8 and the outer bracket 14 disposed on the upper end of the piston rod 6 via Consists of

여기에서, 상기한 바와 같이 스토퍼(20)를 러버 시트(10)와 일체로 부착함과 동시에 스토퍼(20)상에는 돌기(22)를 형성함으로써, 불규칙한 노면의 주행시에 쇽 업소버(2)가 진동하는 경우에 러버 시트(10)에 부착된 스토퍼(20)가 외측 브라켓(14)과 접촉되어도 스토퍼(20)는 곧바로 외측 브라켓(14)으로부터 분리되기 때문에 이음은 발생하지 않게 된다.Here, as described above, the stopper 20 is integrally attached to the rubber seat 10 and the projection 22 is formed on the stopper 20 so that the shock absorber 2 vibrates when the irregular road surface is driven. In this case, even if the stopper 20 attached to the rubber seat 10 is in contact with the outer bracket 14, the stopper 20 is immediately separated from the outer bracket 14, so that no joint occurs.

이상으로 설명한 본 발명에 의하면, 스토퍼가 러버 시트와 일체로 구성되어 있기 때문에 쇽 업소버의 댐핑시에 스토퍼가 외측 브라켓과 접촉되어도 이음이 발생기지 않기 때문에 정숙성을 향상시킬 수 있는 효과를 얻을 수 있다.According to the present invention described above, since the stopper is integrally formed with the rubber seat, no noise occurs even when the stopper comes into contact with the outer bracket during damping of the shock absorber, so that the quietness can be improved.
