Description

차량용 현가장치의 체결구조{The connecting structure of an automotive suspension}Connecting structure of an automotive suspension

본 발명은 차량용 현가장치의 체결구조에 관한 것으로, 보다 상세하게는 부품수를 줄여 조립공정을 단축시킬 수 있도록 된 차량용 현가장치의 체결구조에 관한 것이다.The present invention relates to a fastening structure of a vehicle suspension device, and more particularly, to a fastening structure of a vehicle suspension device that can shorten the assembly process by reducing the number of parts.

일반적으로 차량의 현가 장치는 노면으로부터 오는 진동을 흡수하며 각종 부품들이 받는 충격을 완충시켜 차량의 승차감을 결정할 뿐만 아니라 차체의 선회 시 쏠림을 방지하고 차체의 평형을 유지하는 기능을 하게 된다.In general, the suspension device of the vehicle absorbs the vibration from the road surface and cushions the shock received by various parts to determine the ride comfort of the vehicle, and also prevents the vehicle from turning and maintains the equilibrium of the vehicle body.

이러한 현가장치중 차량의 선회 시 선회 안정성을 유지하기 위한 스테빌라이저(S; Stabilizer)는 도 1에 도시된 바와 같이, 차륜이 장착된 너클과 차체 사이에 구비된 로워아암(LR)에 마운팅부재(1)를 매개로 결합되는데, 이 마운팅부재(1)는 그 일단을 이루는 회전 볼 조인트부위가 로워아암(LR)의 측면으로 돌출된 고정브라켓트(10)에 고정너트(4)를 매개로 고정되고 그 타단이 상기 스테빌라이저(S)의 끝단에 고정너트(4)로 체결된 연결부재(3)에 결합되는 링크로드(2)로 이루어진다.As shown in FIG. 1, a stabilizer (S; Stabilizer) for maintaining a turning stability when turning a vehicle among the suspension devices is mounted on a lower arm LR provided between a knuckle equipped with wheels and a vehicle body. 1) is coupled to the mounting member 1, the rotating ball joint portion constituting one end is fixed via the fixing nut (4) to the fixing bracket (10) protruding to the side of the lower arm (LR) and The other end is composed of a link rod (2) coupled to the connecting member (3) fastened to the end of the stabilizer (S) by a fixing nut (4).

여기서, 상기 링크로드(2)가 결합되는 고정브라켓트(10)부위에는 이 고정브라켓트(10)의 상·하부위에 각각 어퍼·로워컵(7,8)에 안착된 어퍼·로워부시(5,6)가 구비되어 출격을 완충·흡수하게 됨은 물론이다.Here, the upper and lower bushes (5, 6) seated on the upper and lower cups (7, 8) on the upper and lower portions of the fixing bracket (10), respectively, on the fixing bracket (10) to which the link rod (2) is coupled. ) Is provided to cushion and absorb the sortie.

그러나, 이와 같이 스테빌라이저(S)와 로워아암(LR)을 연결하는 마운팅부재(1)는 링크로드(2)의 양 끝단에서 다수의 구성요소들이 순차적으로 결합되므로 이에 따른 조립공수의 증가는 물론 부품제작에 따른 제조비용의 상승을 초래하는 단점이 있음은 물론, 상기 로워아암(LR)부위에 결합된 링크로드(2)를 감싸는 부시(5,6)가 브라켓트(10)와 컵(7,8)사이에 개제되어 있어 로워아암(LR)의 심한 요동에 의해 컵(7,8)의 외부로 돌출 되면서 파손되는 현상이 빈번하게 발생되는 단점이 있게 된다.However, in the mounting member 1 connecting the stabilizer S and the lower arm LR in this way, a plurality of components are sequentially coupled at both ends of the link rod 2, thereby increasing the number of assembly operations. In addition to the disadvantage of causing an increase in the manufacturing cost according to the parts manufacturing, the bush (5,6) surrounding the link rod (2) coupled to the lower arm (LR) portion bracket 10 and the cup (7, 8) there is a disadvantage that the breakage phenomenon frequently occurs while protruding to the outside of the cup (7,8) due to the severe swing of the lower arm (LR).

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 마운팅부재의 링크로드의 결합 요소를 줄여 조립공정을 단순화하면서도 로워아암의 요동에 의한 부시의 파손도 방지함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above, and its purpose is to reduce the coupling element of the link rod of the mounting member, simplifying the assembly process, and preventing damage to the bush due to rocking of the lower arm.

상기와 같은 목적을 달성하기 위한 본 발명은, 차량의 충격을 흡수하여 완충작용을 하는 쇽업소버와 함께 선회 안정성을 유지하는 스테빌라이저가 차륜이 장착된 너클과 차체 사이에 구비된 로워아암에 마운팅부재를 매개로 결합되되, 이 마운팅부재는 스테빌라이저와 로워아암을 연결하는 링크로드와, 이 링크로드의 일단에서 스테빌라이저를 고정하도록 너트결합되는 보올트 형상의 연결부재 및 상기 링크로드의 타단에서 고정브라켓트의 상하·부에서 끼워져 삽입되는 더스트커버와 부시로 이루어진 것을 특징으로 한다.The present invention for achieving the above object, the mounting member to the lower arm provided between the knuckle and the vehicle body is equipped with a stabilizer to maintain the swing stability with the shock absorber that absorbs the shock of the vehicle to act as a shock absorber The mounting member is coupled via a link rod connecting the stabilizer and the lower arm, and a bolt-shaped connecting member which is nut-coupled to fix the stabilizer at one end of the link rod, and fixed at the other end of the link rod. It is characterized by consisting of a dust cover and a bush inserted into the upper and lower parts of the bracket.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 차량용 현가장치의 체결구조 단면도를 도시한 것인바, 본 발명은 차량의 충격을 흡수하여 완충작용을 하는 쇽업소버와 함께 선회 안정성을 유지하는 스테빌라이저(S; Stabilizer)가 차륜이 장착된 너클과 차체 사이에 구비된 로워아암(LR)에 마운팅부재(1)를 매개로 결합되되, 이 마운팅부재(1)는 스테빌라이저(S)와 로워아암(LR)을 연결하는 링크로드(2)와, 이 링크로드(2)의 일단에서 스테빌라이저(S)를 고정하도록 너트(4)결합되는 보올트 형상의 연결부재(3) 및 상기 링크로드(2)의 타단에서 고정브라켓트(10)의 하부에서 끼워져 삽입되는 부시(12)와 더불어 상기 고정브라켓트(10)의 상부에서 끼워져 로워아암(LR)에 결합되는 링크로드(2)의 회전 볼 조인트(2a)부위를 가리는 더스트커버(11)로 이루어진다.Figure 2 is a cross-sectional view of the fastening structure of the suspension device for a vehicle according to the present invention, the present invention is a stabilizer (S; Stabilizer) to maintain the stability of the swing with the shock absorber that absorbs the shock of the vehicle to act as a shock absorber The mounting arm 1 is coupled to the lower arm LR provided between the wheel and the knuckle on which the wheel is mounted, and the mounting member 1 is a link connecting the stabilizer S and the lower arm LR. Rod 2, a bolt-shaped connecting member 3 coupled with a nut 4 to secure the stabilizer S at one end of the link rod 2, and a fixing bracket at the other end of the link rod 2 A dust cover covering a portion of the rotating ball joint 2a of the link rod 2 which is fitted at the upper portion of the fixing bracket 10 and coupled to the lower arm LR together with the bush 12 inserted and inserted at the bottom of the 10. It consists of (11).

이에 따라, 본 발명의 마운팅부재를 이용하여 스테빌라이저(S)와 로워아암(LR)을 연결하려면 먼저, 마운팅부재를 구성하는 링크로드(2)의 일단을 스테빌라이저(S)에 일치시킨 다음 보올트 형상의 연결부재(3)를 관통해 너트(4)를 체결해 고정시킨 다음, 상기 링크로드(2)의 타단을 이루는 볼 조인트(2a)부위를 로워아암(LR)의 브라켓트(10)에 삽입시킨 후, 상기 브라켓트(10)의 하부에서 위로 부시(12)를 삽입하여 결합하고 상기 브라켓트(10)의 상부에서 아래로 더스트커버(11)를 끼워 결합하여 조립을 완성하게 된다.Accordingly, in order to connect the stabilizer S and the lower arm LR by using the mounting member of the present invention, first, one end of the link rod 2 constituting the mounting member is matched with the stabilizer S The nut 4 is fastened by fixing the nut 4 through the connection member 3 having an olt shape, and then the portion of the ball joint 2a that forms the other end of the link rod 2 is attached to the bracket 10 of the lower arm LR. After inserting, the bush 12 is inserted into the upper part of the bracket 10 to be coupled to the upper part, and the dust cover 11 is inserted into the lower part of the bracket 10 to be combined to complete the assembly.

여기서, 상기 링크로드(2)의 볼 조인트(2a)부위에는 외력에 의해 움직이는 스테빌라이저(S)와 로워아암(LR)의 움직임을 구속하지 않도록 베어링이 개재됨은 물론이다.Here, a bearing is interposed between the ball joint 2a of the link rod 2 so as not to restrict the movement of the stabilizer S and the lower arm LR, which are moved by an external force.

이상 설명한 바와 같이 본 발명에 의하면, 스테빌라이저와 로워아암을 양단에서 연결하는 마운팅부재가 너트 체결이 없이 로워아암부위로 결합되면서 1개의 부시만 이용하므로 부품을 축소하면서 조립공수도 함께 줄여 줄 수 있는 효과가 있게 된다.As described above, according to the present invention, since the mounting member connecting the stabilizer and the lower arm at both ends is coupled to the lower arm without using the nut, only one bush is used, thereby reducing the assembly labor while reducing components. Will be.

또한, 본 발명은 로워아암부위에 결합된 부시를 지지하는 컵을 제거해 로워아암의 심한 요동하더라도 컵에 의한 부시의 파손을 완전히 방지할 수 있는 효과가 있음은 물론이다.In addition, the present invention has the effect of completely preventing the breakage of the bush by the cup even if the rocking of the lower arm by removing the cup supporting the bush coupled to the lower arm portion.
