첨부된 도면에 의거하여 본 발명의 실시예를 상세히 설명하기로 한다.An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 4 내지 도 6에 도시된 바와 같이, 본 발명에 의한 차량용 쇽업쇼버 마운팅 기구는, 커플드 토션 빔 액슬(CTBA:Coupled Torsion Beam Axle)에 장착되고 쇽업소버(400)가 리어플로워 센터크로스 멤버(200)에 장착되는 구조를 통해, 제품 강도를 보강할 수 있다는 점에 가장 큰 특징이 있다. 4 to 6, the vehicle shock absorber mounting mechanism according to the present invention is mounted on a coupled torsion beam axle (CTBA: Coupled Torsion Beam Axle), the shock absorber 400 is a rear follower center cross member ( Through the structure mounted on the 200), the greatest feature is that the product strength can be reinforced.

이를 구현하기 위한 구성을 구체적으로 설명하면, 리어플로워 사이드 멤버(100)에는 차체와 휠 사이의 상대 운동을 적절히 조화시키기 위한 현가유닛(300)이 지지브라켓(130)에 지지되면서 고정 설치된다. Specifically, the configuration for implementing this, the rear floor side member 100 is fixed while being supported on the support bracket 130, the suspension unit 300 for properly harmonizing the relative movement between the vehicle body and the wheel.

현가유닛(300)은 스프링 스톱퍼(320)와, 스프링 시트(310)를 개재하여 스프 링 스톱퍼(320)를 탄성적으로 지지하는 스프링(330)를 포함하여 구성된다.The suspension unit 300 includes a spring stopper 320 and a spring 330 elastically supporting the spring stopper 320 via the spring seat 310.

리어플로워 사이드 멤버(100)에는 가이드파이프(140)가 관통 설치된다. 이 가이드파이프(140)에는 쇽업소버(400)을 고정하는 고정볼트(150)의 단부가 삽입되어 가이드된다. 특히, 이 가이드파이프(140)가 설치되는 리어플로워 사이드 멤버(100)의 측부에는, 리어플로워 센터크로스 멤버(200)의 단부가 결합된다.The guide pipe 140 is penetrated to the rear follower side member 100. The guide pipe 140 is inserted into the end of the fixing bolt 150 for fixing the shock absorber 400 is guided. In particular, an end of the rear follower center cross member 200 is coupled to the side of the rear follower side member 100 on which the guide pipe 140 is installed.

이를 위해 리어플로워 센터크로스 멤버(200)는 가이드파이프(140)가 위치한 리어플로워 사이드 멤버(100)의 측부를 향해 절곡되면서 연장되는 결합 단부를 갖는다. To this end, the rear follower center cross member 200 has a coupling end extending while being bent toward the side of the rear follower side member 100 where the guide pipe 140 is located.

즉, 리어플로워 센터크로스 멤버(200)는 가이드파이프(140)를 향해 절곡되면서 연장되는 절곡부(210)와, 리어플로워 사이드 멤버(100)의 측부에 밀착되어 용접되도록 절곡부(210)의 단부가 리어플로워 사이드 멤버(100)의 측부와 대응되는 형상으로 형성되는 고정부(220), 및 고정볼트(150)가 삽입되도록 절곡부(210)의 측벽에 홈 형태로 형성되는 결합홈부(230)를 포함하여 구성된다.That is, the rear follower center cross member 200 is bent toward the guide pipe 140 and extends to be bent 210 and the end of the bent portion 210 to be in close contact with the side of the rear follower side member 100. Fixing portion 220 is formed in a shape corresponding to the side of the rear follower side member 100, and the coupling groove portion 230 is formed in a groove shape on the side wall of the bent portion 210 so that the fixing bolt 150 is inserted It is configured to include.

이와 같이, 리어플로워 센터크로스 멤버(200)의 단부는 리어플로워 사이드 멤버(100)에 용접되어 일체 형태로 고정되고, 리어플로워 센터크로스 멤버(200)의 결합홈부(230)에 삽입되는 고정볼트(150)를 통해 쇽업소버(400)을 고정한다. 따라서, 본 발명은 제품 강성을 보강하고 성능을 향상시킬 수 있다. 이는 쇽업소버를 고정하기 위해 별개 구성인 쇽업쇼버 마운팅브라켓을 사용하는 경우, 쇽업쇼버 마운팅브라켓이 외팔보 형태를 이루므로 제품의 강성이 취약해질 수 있기 때문이다.As such, the end of the rear follower center cross member 200 is welded to the rear follower side member 100 and fixed in one piece, and the fixing bolt is inserted into the coupling groove 230 of the rear follower center cross member 200. The shock absorber 400 is fixed through 150). Therefore, the present invention can reinforce product stiffness and improve performance. This is because when the shock absorber mounting bracket, which is a separate configuration, is used to fix the shock absorber, the shock absorber mounting bracket forms a cantilever shape, which may weaken the rigidity of the product.

본 발명에 따른 쇽업쇼버는 현가유닛의 스프링 고유진동을 제어하여 승차감 을 향상하기 위한 리어 쇽업쇼버(Rear Shock absorber)로서, 피스톤 및 로드가 내장되어 바퀴의 덤핑 및 리바운딩시 상,하유동하면서 충격 및 진동을 억제하는 구조이다. 여기서, 이 리어 쇽업쇼버의 구성은 통상적으로 차량에 사용되는 리어 쇽업쇼버와 동일하므로 이에 대한 자세한 설명은 생략한다.Shock absorber according to the present invention is a rear shock absorber (Rear Shock absorber) for improving the ride comfort by controlling the spring natural vibration of the suspension unit, the piston and the rod is built-in during dumping and rebounding of the wheel while impact and It is a structure that suppresses vibration. Here, since the configuration of the rear shock absorber is the same as the rear shock absorber normally used for a vehicle, a detailed description thereof will be omitted.

상술한 바와 같이, 본 발명의 차량용 쇽업쇼버 마운팅 기구의 경우 쇽업소버가 리어플로워 사이드 멤버에 결합되는 리어플로워 센터크로스 멤버의 결합 단부에 장착되므로, 제품의 강성 및 성능을 향상하고 제품 중량을 감소하며 원가를 절감할 수 있다는 장점이 있다. As described above, in the case of the vehicle shock absorber mounting mechanism of the present invention, the shock absorber is mounted on the engaging end of the rear follower center cross member coupled to the rear follower side member, thereby improving the rigidity and performance of the product and reducing the product weight. The advantage is that cost can be reduced.

이로써, 쇽업쇼버 마운팅브라켓이 외팔보 형태로 장착됨에 따라 제품 강성이 취약해지고, 쇽업쇼버 마운팅브라켓 및 레인포스 등의 구성 추가로 인해 제조 원가가 증가된다는 종래 기술의 문제를 본 발명은 해결할 수 있다. Thus, the present invention can solve the problem of the prior art that the product rigidity is weakened as the shock absorber mounting bracket is mounted in the cantilever shape, and the manufacturing cost is increased due to the addition of the shock absorber mounting bracket and the rain force.

본 발명을 바람직한 실시 예를 사용하여 상세히 설명하였으나, 본 발명의 범위는 특정 실시 예에 한정되는 것은 아니며, 첨부된 특허청구범위에 의하여 해석되어야 할 것이다. 또한, 이 기술분야에서 통상의 지식을 습득한 자라면, 본 발명의 범위에서 벗어나지 않으면서도 많은 수정과 변형이 가능함을 이해하여야 할 것이다.Although the present invention has been described in detail using the preferred embodiments, the scope of the present invention is not limited to the specific embodiments, it should be interpreted by the appended claims.
