Description

차량의 로우아암구조{Lower arm structure in vehicle}Lower arm structure in vehicle

본 발명은 차량의 현가장치를 구성하는 로우아암에 관한 것으로, 특히 차량의 중량과 원가 절감 및 내구성 향상을 위해 스태빌라이저바아 링크를 마운팅하기 위한 브라켓과 보강판이 일체로 형성된 차량의 로우아암구조에 관한 것이다.The present invention relates to a low arm constituting a suspension device of a vehicle, and more particularly, to a low arm structure of a vehicle in which a bracket and a reinforcement plate are integrally installed for mounting a stabilizer bar link to reduce weight, cost, and durability of the vehicle. .

종래 차량의 현가장치를 구성하는 로우아암은 통상적으로 차륜과 차체 사이에 개재되어 차륜을 차체에 지지시키는 역할을 하는 것으로서 도 1에 도시한 바와 같이 대체로 Ｌ자 형상을 이루는 로우아암(10)은 차륜에 체결되는 차륜 체결부(10a)와 차체에 체결되는 2개의 차체 체결부(10b)를 각각 구비하고 있다.The lower arm constituting the suspension of a conventional vehicle is typically interposed between the wheel and the body to support the wheel to the vehicle body. As shown in FIG. 1, the lower arm 10 having a generally L-shape has a wheel shape. And a vehicle body fastening portion 10b fastened to the vehicle body and two vehicle body fastening portions 10b fastened to the vehicle body.

또한 상기 로우아암(10)은 차량의 주행중에 불규칙한 노면으로부터의 진동이나 충격을 흡수하는 쇽 업소버를 장착하기 위한 쇽 업소버 장착 브라켓(10c)과, 차량의 롤링을 억제하기 위해 설치되는 스태빌라이저 바아의 링크를 연결하기 위한 스태빌라이저바아 링크 연결 브라켓(10d)도 구비하고 있다.In addition, the lower arm 10 is a shock absorber mounting bracket (10c) for mounting a shock absorber for absorbing vibrations or shocks from irregular road surface while driving the vehicle, and a linkage of the stabilizer bar is installed to suppress the rolling of the vehicle Also provided with a stabilizer bar link connecting bracket (10d) for connecting.

그리고 상기 로우아암(10)은 도 2에 도시한 바와 같이 상부 패널(11a)에 하부 패널(11b)이 결합된 2중 패널 구조로 이루어고, 상기 상부 패널과 하부 패널 사이에는 구조적인 강성을 증대시키기 위해 박스 형상의 빈 공간이 형성되며, 이 빈 공간의 내부에 강성을 보강하기 위한 보강판(12)이 추가로 부착된다.In addition, the lower arm 10 has a double panel structure in which the lower panel 11b is coupled to the upper panel 11a as shown in FIG. 2, and increases structural rigidity between the upper panel and the lower panel. In order to make a box-shaped empty space is formed, a reinforcing plate 12 for reinforcing rigidity is further attached to the interior of the empty space.

상기 보강판(12)은 도 3에 도시한 바와 같이 상기 상부 패널(11a)의 내측면에 부착되어 강성을 보강하게 되어 있다.The reinforcement plate 12 is attached to the inner surface of the upper panel 11a as shown in FIG. 3 to reinforce rigidity.

그런데 상기와 같은 종래의 로우아암구조에서는 스태빌라이저바아 링크 연결 브라켓(10d)과 보강판(12)이 별개로 형성되어 있어서 부품수가 많고 그에 따른 제작공정수가 증대되어 차량의 원가 절감 측면에서 불리하며, 상기 보강판(12)이 단지 상부 패널의 내측면에만 부착되어서 있어서 보강판에 의한 강성 보강이 미흡하다고 하는 결점이 있었다.However, in the conventional low arm structure as described above, the stabilizer bar link connecting bracket 10d and the reinforcement plate 12 are separately formed, so that the number of parts is increased and the number of manufacturing processes increases accordingly, which is disadvantageous in terms of cost reduction of the vehicle. Since the reinforcement plate 12 is only attached to the inner side of the upper panel, there is a drawback that the rigid reinforcement by the reinforcement plate is insufficient.

이에 본 발명은 상기한 사정을 감안하여 안출된 것으로, 로우아암의 구조적인 강성을 증대시키는 보강판에 스태빌라이저 바아 링크 연결부를 일체로 형성하여 부품수를 줄여서 차량의 중량 및 원가 절감을 도모할 수 있고, 보강판을 상부 패널과 하부 패널의 접합부까지 연장해서 일체로 부착하여 로우아암의 구조적인 강성을 효과적으로 증대시켜 로우아암의 내구성을 향상시킬 수 있도록 한 차량의 로우아암구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above circumstances, by forming the stabilizer bar link connection integrally to the reinforcement plate to increase the structural rigidity of the low arm can reduce the number of parts to reduce the weight and cost of the vehicle In addition, the purpose of the present invention is to provide a low arm structure of a vehicle in which the reinforcement plate is extended to the junction of the upper panel and the lower panel to be integrally attached, thereby effectively increasing the structural rigidity of the lower arm, thereby improving durability of the lower arm. .

상기와 같은 목적을 달성하기 위한 본 발명은, 상부 패널에 하부 패널이 결합하여 형성된 박스 형상의 빈 공간에 보강판이 삽입되어 상기 상부 패널과 하부 패널에 각각 일체로 부착되고, 상기 보강판의 일측면에는 스태빌라이저바아 링크를 연결하기 위한 스태빌라이저 바아 링크 연결부가 일체로 형성된 것을 특징으로 한다.The present invention for achieving the above object, the reinforcing plate is inserted into the box-shaped empty space formed by coupling the lower panel to the upper panel is integrally attached to each of the upper panel and the lower panel, one side of the reinforcing plate The stabilizer bar link connection for connecting the stabilizer bar link is characterized in that formed integrally.

이상 설명한 바와 같이 본 발명에 따른 차량의 로우아암구조에 의하면, 로우아암의 구조적인 강성을 증대시키는 보강판에 스태빌라이저바아 링크를 연결하기 위한 스태빌라이저바아 링크 연결부가 일체로 형성되어서 로우아암의 부품수를 저감하여 차량의 중량 및 원가 절감을 도모할 수 있고, 상기 보강판이 로우아암을 구성하는 상부 패널과 하부 패널에 동시에 부착됨에 따라 로우아암의 내구성이 향상되고 사용 수명이 연장되는 등의 효과가 있다.As described above, according to the low arm structure of the vehicle according to the present invention, the stabilizer bar link connecting portion for connecting the stabilizer bar link is integrally formed on the reinforcement plate to increase the structural rigidity of the low arm, thereby reducing the number of parts of the low arm. The weight and cost of the vehicle can be reduced, and the reinforcement plate is simultaneously attached to the upper panel and the lower panel of the lower arm, thereby improving the durability of the lower arm and extending the service life of the lower arm.

이하 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 4에는 본 발명에 따른 로우아암의 분리 사시도가 도시되어 있는 바, 즉 로우아암(1)은 상부 패널(1a)에 하부 패널(1b)이 박스 형상의 빈 공간을 형성하도록 결합되는 2중 패널 구조로 이루어지고, 상기 상부 패널과 하부 패널에는 쇽 업소버를 장착하기 위한 쇽 업소버 장착 브라켓(2)이 일체로 부착되며, 상기 박스 형상의 공간 내부에는 강성을 보강하기 위한 보강판(3)이 삽입되어 일체로 부착된다.4 shows an exploded perspective view of the lower arm according to the present invention, i.e., the lower arm 1 is a double panel in which the lower panel 1b is coupled to the upper panel 1a to form a box-shaped empty space. The upper panel and the lower panel are integrally attached to the shock absorber mounting bracket 2 for mounting the shock absorber, and a reinforcement plate 3 for reinforcing rigidity is inserted into the box-shaped space. And are integrally attached.

또한 상기 보강판(3)에는 스태빌라이저 바아 링크를 연결하기 위한 스태빌라이저 바아 링크 연결부(4)가 일체로 형성되는 데, 이 스태빌라이저 바아 링크 연결부(4)는 상기 보강판(3)의 일측면에서 수직한 방향으로 연장된 형태로 형성된다.In addition, the stabilizer bar link connecting portion 4 for integrally connecting the stabilizer bar link is formed on the reinforcing plate 3, and the stabilizer bar link connecting portion 4 is perpendicular to one side of the reinforcing plate 3. It is formed in a shape extending in the direction.

상기와 같이 보강판(3)에 스태빌라이저 바아 링크 연결부(4)가 일체로 형성 됨에 따라 종래의 별물로 제작되는 것에 비해 로우아암의 부품수가 감소하여 제작이 용이해지고, 로우아암의 중량 및 원가 절감을 도모할 수 있게 된다.As the stabilizer bar link connecting portion 4 is integrally formed on the reinforcing plate 3 as described above, the number of parts of the lower arm is reduced compared to that of the conventional separate product, thereby making the production easier and reducing the weight and cost of the lower arm. It becomes possible to plan.

그리고 상기 보강판(3)은 도 6에 자세히 도시된 바와 같이 상기 스태빌라이저 바아 링크 연결부(4)가 일체로 형성된 측면이 하부로 연장되게 형성되어서 연장부(3a)를 구비하고 있다.And the reinforcement plate 3 is formed in such a way that the side of which the stabilizer bar link connecting portion 4 is integrally formed to extend downward as shown in detail in FIG. 6 and has an extension portion 3a.

상기 연장부(3a)는 도 5에서 단면으로 도시한 바와 같이 상기 상부 패널(1a)과 하부 패널(1b)이 접합되는 부위까지 연장되게 형성되어 상기 하부 패널(1b)에 일체로 부착된다. 즉 상기 보강판(3)은 박스 형상의 빈 공간에 삽입되어서 상부 패널(1a)에 그 대부분의 부위가 일체로 부착됨과 더불어 상기 연장부(3a)는 하부 패널의 일부분까지 연장되어서 부착됨으로써, 보강판(3)이 상부 패널과 하부 패널에 일체로 결합되게 되는 것이다.As shown in cross section in FIG. 5, the extension part 3a is formed to extend to a portion where the upper panel 1a and the lower panel 1b are joined to be integrally attached to the lower panel 1b. That is, the reinforcing plate 3 is inserted into the empty space of the box shape so that most of the parts are integrally attached to the upper panel 1a, and the extension part 3a is extended to be attached to a part of the lower panel, thereby reinforcing the reinforcement. The plate 3 is to be integrally coupled to the upper panel and the lower panel.

상기와 같이 보강판(3)이 상부 패널과 하부 패널에 동시에 접합됨에 따라 보강판에 의해 로우아암의 구조적인 강성이 한층 증대되어 로우아암의 내구성을 향상시킬 수 있게 되는 것이다.As described above, as the reinforcing plate 3 is bonded to the upper panel and the lower panel at the same time, the structural rigidity of the lower arm is further increased by the reinforcing plate, thereby improving durability of the lower arm.
