In particular, the structure is simple and lightweight, and the design freedom is excellent, and the front lower arm intrudes into the body floor frame during a collision. The present invention relates to an installation structure of the front lower arm for the McPherson type suspension of a passenger car, which can improve the collision stability.
일반적으로 차량의 서스펜션은 차축과 차체를 연결하여 주행중에 차축이 노면으로부터 받는 진동이나 충격을 차체에 직접적으로 전달되지 않도록 제어하여 차체와 화물의 손상을 방지하고 승차감을 좋게 만드는 장치로서 노면으로부터 충격을 완화시키는 섀시 스프링과, 섀시 스프링의 자유진동을 제어하여 승차감을 좋게 하는 쇽 업소버 및 차량의 롤링을 방지하는 스태빌라이저 등으로 구성된다.In general, the suspension of the vehicle is connected to the axle and the body so that the vibration or shock received from the road surface is not directly transmitted to the body while driving, thereby preventing damage to the body and cargo and improving ride comfort. And a chassis spring for mitigating, a shock absorber for controlling the free vibration of the chassis spring to improve ride comfort, and a stabilizer for preventing rolling of the vehicle.
그리고 맥퍼슨형(스트러트식) 서스펜션에서 크로스멤버가 없는 상태로 프론트로어아암이 설치된 구조는 도 1에 도시된 바와 같이, 차체플로어프레임(10)의 전방부 좌우측에 프론트사이드멤버(20)가 고정됨과 더불어 상기 차체플로어프레임(10)의 전방하부 쪽으로 돌출된 돌출부(11)에 용접되는 브라켓트(30)를 매개로 프론트사이드멤버(20)의 길이방향중심이 지지되는 한편, 상기 돌출부(11)의 하부면에 서스펜션을 구성하는 프론트로어아암(40)의 2곳의 힌지부가 고정된 구조로 되어 있다.And the structure of the front lower arm in the state without the cross member in the McPherson type (strut type) suspension, as shown in Figure 1, the front side member 20 is fixed to the front left and right sides of the body floor frame 10 and In addition, the longitudinal center of the front side member 20 is supported by the bracket 30 welded to the protrusion 11 protruding toward the front lower portion of the body floor frame 10, while the lower portion of the protrusion 11 is supported. The two hinge parts of the front lower arm 40 which comprise a suspension on the surface are fixed.
또한 맥퍼슨형(스트러트식) 서스펜션에서 크로스멤버가 있는 상태에서 프론트로어아암이 설치된 구조는 도 2에 도시된 바와 같이, 차체플로어프레임(10)의 전방부 좌우측에 프론트사이드멤버(20)가 고정됨과 더불어, 상기 차체플로어프레임(10)의 전방하부와 프론트사이드멤버(20)의 길이방향중심이 지지되도록 전방크로스멤버(50)가 설치되는 한편, 상기 프론트사이드멤버(20)의 소정위치와 전방크로스멤버(50)의 소정위치에 브라켓트(60)가 설치됨과 더불어, 상기 전방크로스멤버(50)의 하부면 앞뒤쪽에 프론트로어아암(40)의 2곳의 힌지부가 고정되어 있다.In addition, the structure of the front lower arm is installed in the state of the cross member in the McPherson type (strut type) suspension, as shown in Figure 2, the front side member 20 is fixed to the front left and right sides of the body floor frame 10 and In addition, the front cross member 50 is installed so that the front lower part of the body floor frame 10 and the longitudinal center of the front side member 20 are supported, while a predetermined position and front cross of the front side member 20 are supported.
