본 발명은 차량용 현가장치에 관한 것으로, 보다 상세하게는 알루미늄 재질 컨트롤암을 이용한 차량용 현가장치에 관한 것이다.The present invention relates to a vehicle suspension, and more particularly to a vehicle suspension using an aluminum control arm.

일반적으로 주행 중 차량이 노면의 불균일로부터 소음을 수반하는 진동을 받게 되면서 차체가 흔들리는 현상을 방지하는 현가장치는 스프링과 쇽업소버(Shock Absober) 및 스테빌라이져 등으로 구성되어, 대체로 스프링상수와 댐핑력 및 차고조종의 3가지 기능을 주로 하면서 차량의 승차감과 안정성을 개선하는 역할을 한다.In general, the suspension system that prevents the vehicle body from shaking while the vehicle receives vibrations from the unevenness of the road surface is composed of a spring, shock absorber and stabilizer, and the spring constant, damping force and It mainly plays three functions of garage control, and plays a role of improving the ride comfort and stability of the vehicle.

이와 같은 현가장치를 구성하는 구성 요소 중 주요 부품중 하나인 컨트롤암은 차량 조립 시, 한 부위는 볼 조인트를 매개로 조향 너클에 연결되고 다른 부위는 부시와 함께 축을 매개로 하여 프레임에 연결되며, 이와 같이 조립되는 컨트롤암은 자동차의 주행시 바퀴로부터 여러 방향으로 동시에 힘이 전달되어져 내구성이 요구되는 부품임은 물론이다.One of the main components of the suspension system, the control arm, is connected to the steering knuckle through the ball joint and the other part is connected to the frame through the shaft with the bush when assembling the vehicle. The control arm assembled as described above is a component that requires durability as the force is simultaneously transmitted in various directions from the wheel when the vehicle is driven.

이에 따라, 통상 상기 컨트롤암은 차륜의 너클을 통해 들어오는 차량의 전·후방 하중뿐만 아니라 내·외향 하중을 지지하도록 강성을 갖는 강(Steel)재질로 이루어지게 된다.Accordingly, the control arm is usually made of a steel (Steel) having a rigid so as to support not only the front and rear loads of the vehicle coming through the wheel knuckles, but also the inward and outward loads.

그러나, 이와 같은 강 재질 컨트롤암은 철재 판재를 4종의 프레스 부품 단품과 부시를 별도로 제작한 후 서로간에 용접되는 5종의 단품 복합 구조를 이루므로, 다수의 금형과 성형공정이 필요함은 물론 용접 품질에 따른 품질 불량 의존성이 높은 한계가 있가.However, the steel control arm is made of four kinds of press parts and steel parts separately, and then made of five kinds of single-piece composite structures welded to each other, so that a large number of molds and molding processes are required, as well as welding. Is there a high limit on the quality defect dependence on quality?

또한, 철재의 특성상 중량이 무겁고 부품의 내식성 확보를 위해 전착도장 피막처리를 해야 만 되어, 작업 공정이 증가되는 취약성이 있게 된다.In addition, due to the characteristics of the steel is heavy, and the electrodeposition coating to be treated to ensure the corrosion resistance of the parts, there is a vulnerability to increase the work process.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 컨트롤암을 알루미늄 재질로 용접이 없이 압출 성형해 용접에 따른 품질 저하를 없애면서 부품 경량화를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above, and an object of the present invention is to provide a lightweight component while eliminating the quality degradation caused by welding by extruding the control arm with aluminum without welding.

상기 안착부를 형성하도록 압출 성형되는 제1압출연장단과 제2압출연장단은, 상기 인너 테두리의 저부 부위에서 압출 성형되는 제1압출연장단이 테두리부의 끝에서 일체로 압출 성형되는 제2압출연장단에 떨어진 위치에서 접촉되도록 경사지게 연장됨에 따라, 상기 제1압출연장단과 제2압출연장단이 접촉되지 않는 부위에는 속인 빈 폐 단면인 제2중공이 형성되어진 연결부를 형성하고,
상기 안착부를 형성하는 테두리부가 그 길이 방향으로 안착부에 비해 상대적으로 좁은 폭을 이루도록 이어져 양 쪽 끝단 부위를 형성해, 서브프레임과 너클 부위로 각각 체결되는 프레임·너클 체결단을 형성한 것을 특징으로 한다.In the present invention for achieving the above object, in the control arm manufactured by the extrusion molding method of extrusion molding using an aluminum extrusion profile,
An outer inner edge protruding at a predetermined height forms a first hollow forming a closed cross section of a hollow space therein, and an edge portion forming an overall shape symmetrical with respect to the longitudinal direction is formed,
The first extrusion extension end that is extruded from the bottom portion of the inner edge constituting the both edges symmetric with each other extends obliquely, and the second extrusion extension end is integrally extruded from the end of the edge portion, the first extrusion extension end and the first 2 Extruded extension ends form a seating part through close contact parts overlapping each other so that no gap is formed between them,
The first extrusion extension end and the second extrusion extension end that are extruded to form the seating part have a second extrusion extension end that is integrally extruded from the end of the edge by the first extrusion extension end extruded at the bottom portion of the inner edge. As it extends inclined so as to contact at a position away from, the first compression extension end and the second compression extension end are not in contact with each other to form a connection portion in which a second hollow, which is a hollow closed cross section, is formed.
The edge portion forming the seating portion has a relatively narrow width compared to the seating portion in the longitudinal direction thereof to form both end portions, and forms frame and knuckle fastening ends respectively fastened to the subframe and the knuckle portion. .

상기 테두리부(2)에서 안쪽으로 경사지게 연장되면서 그 내부가 속이 빈 폐 단면 공간인 제2중공을 이루도록 연결부(4)가 연장 형성되며, The connecting portion 4 is extended to be inclined inward from the edge portion 2 to form a second hollow, the inside of which is a hollow closed cross-sectional space,

상기 연결부(4)에 일체로 형성되면서 새시스프링이 안착되도록 넓게 형성되는 안착부(8)가 형성되고, The mounting portion 8 is formed integrally with the connecting portion 4 is formed so that the seat spring is seated wide,

상기 안착부(8)에 비해 상대적으로 좁은 폭을 이루도록 안착부(8)의 양 측 면에서 연장되면서 테두리부(2)의 양 쪽 끝단부위를 이루어 서브프레임과 너클부위에 각각 체결되는 체결단(A,B)을 형성하는 구조를 이루게 된다. A fastening end extending from both sides of the seating portion 8 to form a relatively narrower width than the seating portion 8 and forming both end portions of the edge portion 2 to be fastened to the subframe and the knuckle portion, respectively.
