본 발명은 자동차의 어퍼암에 관한 것으로, 특히, 알루미늄 압출재의 연결부를 커팅하고, 제1,제2압출부를 절곡하여 양측으로 벌려주고, 끝단부분을 압착 성형하므로 제1,제2부시고정부 및 액슬고정부를 형성하고, 제1,제2부시고정부 및 액슬고정부에 액슬 및 부시를 압입 또는 고정하기 위한 제1,제2부시고정홀 및 액슬홀을 형성하므로 용접이나 후 가공을 없애고, 제작시간을 단축시켜 제조단가를 절감하고, 제조효율을 증대하도록 하는 자동차의 어퍼암 및 그 제조방법에 관한 것이다.The present invention relates to an upper arm of an automobile, and in particular, by cutting the connecting portion of the aluminum extrusion material, bending the first and second extruded parts to open to both sides, and the end portion is press-molded, so that the first and second subsidiary fixing parts and axles Forming the fixed part, and forming the first and second sub-fixing hole and axle hole for pressing or fixing the axle and bush in the first and second sub-fixing part and the axle fixing part, eliminating welding or post-processing, The present invention relates to a vehicle upper arm and a method of manufacturing the same, which reduce the manufacturing cost by reducing the manufacturing cost and increase manufacturing efficiency.

일반적으로, 서스펜션(SUSPENSION)은 차축과 차체를 연결하여 주행할 때 노면에서 받는 진동이나 충격을 차체에 직접 전달되지 않도록 하여 차체나 화물의 손상을 방지하고 승차감을 좋게 하는 장치로서, 더블 위시본이나 멀티 링크 타입 현가장치가 최근에 많이 사용되고 있다.In general, the suspension (SUSPENSION) is a device that prevents damage to the vehicle body or cargo and improves the ride comfort by preventing the vibration or shock received from the road surface directly when driving connecting the axle and the vehicle body, and improves the ride comfort. Multi-link suspensions have been widely used in recent years.

한편, 더블 위시본형 서스펜션구조는 도 1에 도시하고 있는 바와 같이, 좌, 우측 전륜의 휠과 결합되는 너클(10)과, 상기 너클(10)의 상, 하단에 볼조인트(미도시)를 매개로 각각 결합되어 휠의 움직임을 조절하는 어퍼암(8) 및 로어암(12) 과, 상기 로어암(12)에 좌우 양측단부가 각각 결합되어 차체가 옆으로 흔들리는 것을 방지하는 스태빌라이저바(S)와, 차량을 운행 시 타이어가 지면과 접촉하면서 발생되는 충격을 완화시키는 코일스프링(16) 및 상기 코일스프링(16)의 자유진동을 억제하여 승차감을 좋게 하는 쇽업소버(18)가 구비되면서 종축방향으로 설치되는 스트럿어셈블리(14)로 구성되어 있다.Meanwhile, as shown in FIG. 1, the double wishbone suspension structure has a knuckle 10 coupled to wheels of the left and right front wheels, and a ball joint (not shown) on the upper and lower ends of the knuckle 10. The upper arm 8 and the lower arm 12 are coupled to each other to control the movement of the wheel, and the left and right both ends are coupled to the lower arm 12, respectively, to stabilize the stabilizer bar (S) And a coil spring 16 for alleviating the shock generated when the tire comes into contact with the ground when driving the vehicle, and a shock absorber 18 for suppressing free vibration of the coil spring 16 to improve ride comfort, while being provided with a longitudinal axis direction. Strut assembly 14 is installed.

또한, 상기 스트럿어셈블리(14)의 외측부에는 프론트사이드멤버(6)의 전후양측에 하부가 용착된 상태로 휠하우징커버(2)가 설치되고, 상기 휠하우징커버(2)의 일측부에는 하단부가 프론트사이드멤버(6)의 일측면에 있는 휠하우징패널(5)이 부착 설치된다.In addition, the outer side of the strut assembly 14, the wheel housing cover (2) is installed on the front and rear sides of the front side member (6) in a state in which the bottom is welded, the lower portion of the wheel housing cover (2) The wheel housing panel 5 on one side of the front side member 6 is attached.

이러한 종래 더블 위시본형 프론트서스펜션구조는 차량을 운행 중 선회를 수행시 어퍼암(8)을 통해 비틀림하중이 전달되면, 상기 어퍼암(8)을 통해 전달되는 비틀림 하중이 보강부재(미도시)에 의해 흡수된 후 휠하우징커버(2)를 통해 분산이 이루어지게 됨은 물론, 차량을 운행 시 타이어가 지면과 접촉하면서 발생되는 충격이나 상하진동은 스트럿어셈블리(14)에 의해 흡수가 이루어지고 있다In the conventional double wishbone type front suspension structure, when a torsional load is transmitted through the upper arm 8 when the vehicle turns while driving, the torsional load transmitted through the upper arm 8 is applied to the reinforcing member (not shown). After being absorbed by the wheel housing cover 2, the dispersion is made, as well as the shock or vertical vibration generated when the tire is in contact with the ground when the vehicle is driven is absorbed by the strut assembly 14.

한편, 상기한 어퍼암(8)은 제조하기 위하여서는 주로 스틸판재를 소성가공하거나 단조공법으로 제작하여 사용하였다.On the other hand, in order to manufacture the upper arm 8, the steel plate is mainly used by plastic working or forging.

그리고, 최근에는 차체를 경량화하기 위하여 알루미늄을 적용하지만, 구조적인 안정성을 위하여 재질의 강도, 휨 또는 비틀림 등에 대하여 기계적인 특성이 우수한 단조공법 등이 주로 이용되고 있다.In recent years, aluminum is applied to reduce the weight of the vehicle body, but a forging method that is excellent in mechanical properties with respect to strength, warpage, or torsion of a material is mainly used for structural stability.

그러나, 알루미늄 단조공법은, 고가의 단조처리장치 등의 대형설비가 필요하 고, 성형시간, 후가공 및 열처리시간 길고, 단조 후의 원소재 수율이 낮아서 어퍼암의 생산성 및 작업성이 저하하며, 생산단가가 증가하는 문제점을 지녔다.However, the aluminum forging method requires large equipment such as an expensive forging treatment device, a long forming time, a post processing and a heat treatment time, a low yield of raw materials after forging, and a lower productivity and workability of the upper arm.
