Description

현가장치의 컨트롤 암 구조{Control arm structure for suspensions}Control arm structure for suspension

본 발명은 현가장치의 컨트롤 암 구조에 관한 것으로, 특히 3개의 차체 구조물을 하나의 볼 조인트로 연결하여 컨트롤 암의 중량을 절감할 수 있는 현가장치의 컨트롤 암 구조에 관한 것이다.The present invention relates to a control arm structure of a suspension device, and more particularly, to a control arm structure of a suspension device that can reduce the weight of the control arm by connecting three vehicle body structures with one ball joint.

일반적으로 차량의 현가장치는 차축과 차체를 연결하고, 주행 중에 노면의 진동과 충격을 흡수하여 승차감과 선회 안정성을 높이기 위한 장치이다.In general, the suspension of the vehicle is a device for connecting the axle and the vehicle body, and absorbs the vibration and shock of the road surface while driving to increase the riding comfort and turning stability.

이러한 현가장치는 노면으로부터 전달되는 충격을 완화하기 위하여 상하방향의 연결이 유연하여야 하며, 휠에 발생되는 구동력, 제동력, 선회 시의 원심력 등을 이겨낼 수 있는 수평방향의 연결이 견고해야 한다.In order to alleviate the impact transmitted from the road surface, the suspension system should be flexible in the vertical direction, and the horizontal connection should be strong to overcome the driving force, the braking force, and the centrifugal force during the turning.

한편, 현가장치는 독립식과 일체식 현가장치로 분류되며, 본 발명은 독립식 현가장치에 적용이 가능한 컨트롤 암에 관한 것으로, 컨트롤 암은 휠의 움직임을 컨트롤하는 암(arm)의 역할을 하는 부재이다.On the other hand, the suspension is classified into independent and integrated suspension, the present invention relates to a control arm applicable to the independent suspension, the control arm is a member that serves as an arm for controlling the movement of the wheel (arm) to be.

도 1에 도시된 바와 같이, 일반 어퍼 컨트롤 암(10)은 상단 볼조인트와 결합되도록 볼조인트결합구(11a)가 형성된 볼조인트결합부(11)와, 이 볼조인트결합부(11)와 일체로 연장 형성되어 스트럿어셈블리의 상단과 결합되는 스트럿어셈블리결합부(12)와; 이 스트럿어셈블리결합부(12)의 선단쪽 양측부에 절곡형성되어 어퍼암부시(20)가 결합되는 어퍼암부시결합구(13a)가 형성된 어퍼암부시결합부(13)가 일체로 구성된다.As shown in FIG. 1, the general upper control arm 10 includes a ball joint coupling part 11 in which a ball joint coupling hole 11a is formed so as to be engaged with an upper ball joint, and the ball joint coupling part 11. A strut assembly coupling part 12 extending to be coupled to an upper end of the strut assembly; The upper arm bushing engaging portion 13 is formed integrally with the upper arm bushing engaging portion 13a, which is bent and formed at both ends of the strut assembly coupling portion 12, and the upper arm bushing 20 is coupled thereto.

어퍼암부시(20)에는 미도시된 샤프트가 나사체결되어 결합되며, 이 샤프트에는 스트럿어셈블리마운팅 브래킷이 체결되어 스트럿어셈블리의 상단이 결합된다.The upper arm bush 20 is coupled to the shaft not shown is screwed, the strut assembly mounting bracket is fastened to the shaft is coupled to the upper end of the strut assembly.

그러나, 종래의 컨트롤 암은 강판을 압축하여 제작되므로, 차체 설계 상에 있어 차량 중량 절감에 한계가 있다.However, since the conventional control arm is manufactured by compressing the steel sheet, there is a limit to the vehicle weight reduction in the vehicle body design.

본 발명은 상기의 결점을 해소하기 위한 것으로, 인장력 또는 압축력만이 작용하도록 2개의 링크로 이루어진 컨트롤 암을 구성하여, 컨트롤 암의 구성 부품을 경량화할 수 있는 현가장치의 컨트롤 암 구조에 관한 것이다.The present invention relates to a control arm structure of a suspension device capable of reducing the components of the control arm by constituting a control arm composed of two links such that only a tensile force or a compressive force acts.
