Abstract

A stabilizer bar link is provided to generate the reaction force and increase the stability of the traveling performance by ball-jointing the first and second links at the body and the stabilizer. A stabilizer bar link is composed of first and second links(110,120) whose both ends are mounted with first and second ball joints(111,121) mutually combined by a hinge pin(130). The first ball joint is combined at the body, and the second ball joint is jointed at the stabilizer bar. The stability of the traveling performance of the vehicle is improved by generating the reaction force for the rolling of the stabilizer and preventing the stabilizer from being deformed for other operating force.

본 발명은 스태빌라이저 바 링크에 관한 것으로, 특히 스태빌라이저 바가 롤링에 대해서만 반력을 발생시키며 횡력과 같은 다른 작용력에 대해서는 변형되지 않도록 하는 차량의 스태빌라이저 바 링크에 관한 것이다.The present invention relates to a stabilizer bar link, and more particularly to a stabilizer bar link of a vehicle such that the stabilizer bar generates a reaction force only against rolling and does not deform against other action forces such as lateral forces.

차량의 현가장치는 차축과 차체를 연결하여 주행 중에 차축이 노면으로부터 받는 진동이나 충격을 차체에 직접 전달하지 않도록 하여 차체와 화물의 손상을 방지하고 승차감을 높이는 역할을 한다.Suspension of the vehicle connects the axle and the body so as not to directly transmit the vibration or shock received from the road surface to the vehicle body while driving, thereby preventing damage to the body and cargo and enhancing ride comfort.

한편, 승차감을 좋게 하기 위하여 스프링 상수가 작은 스프링을 사용하면 선회 시에 작용하는 원심력 때문에 차체의 기울기가 증대한다. 독립현가식의 차량에서는 이러한 경향이 크기 때문에 선회시의 롤을 감소시켜 차체의 평형을 유지하기 위한 토션바를 이용한 스태빌라이저를 장착하고 있다.On the other hand, when a spring with a small spring constant is used to improve ride comfort, the inclination of the vehicle body increases due to the centrifugal force acting at the time of turning. In the case of a self-sustaining vehicle, such a tendency is large, and it is equipped with a stabilizer using a torsion bar to reduce the roll in turning to balance the vehicle body.

스태빌라이저는 양단이 좌우의 로어 암에 고정되며 중앙부는 서브프레임에 고정되어 좌우의 바퀴가 동시에 상하 작동하는 경우에는 작용하지 않지만, 좌우의 바퀴가 서로 상하 작동하는 경우에는 스태빌라이저가 비틀려서 그 때 발생하는 스프링력에 의해 차체의 기울기를 감소시킨다.Stabilizers are fixed to the lower arm on both sides and the center part is fixed to the subframe so that the left and right wheels do not work when the left and right wheels work up and down at the same time. The spring force reduces the inclination of the bodywork.

도 1은 종래의 스태빌라이저 바를 보여주는 도면으로, 스태빌라이저 바(10)는 부싱(21)이 개재되어 브라켓(20)에 의해 서브프레임(미도시)에 볼트 체결되며, 양측 단부에는 링크(30)에 의해 로어암 조립체(40)에 볼트 체결된다.1 is a view showing a conventional stabilizer bar, the stabilizer bar 10 is bolted to the subframe (not shown) by the bracket 20 with the bushing 21 interposed, by the link 30 at both ends Bolted to the lower arm assembly 40.

그러나, 이와 같은 종래의 스태빌라이저 바는 횡력이 발생 시에 불필요한 밴딩(bending)에 의한 반력을 발생시켜 차체에 영향을 주는 문제점이 있다.However, such a conventional stabilizer bar has a problem of affecting the vehicle body by generating reaction force due to unnecessary bending when a lateral force is generated.

구체적으로 살펴보면 도 2는 종래의 스태빌라이저 바 링크의 작동예를 보여주는 도면으로, 스태빌라이저 바(10)의 단부는 링크(30) 상단과 볼트 체결되며 링크(30) 하단은 다시 로어암 조립체(40)에 볼트 체결되므로, 횡방향으로 횡력(F1)이 작용 시에 횡력(F1)이 스태빌라이저 바(10)의 길이 방향으로 작용하며 스태빌라이저 바(10)는 이러한 횡력(F1)에 대한 반력(F2)에 의해 불필요한 밴딩이 발생하여 차체에 영향을 줄 수가 있다.Specifically, Figure 2 is a view showing the operation of the conventional stabilizer bar link, the end of the stabilizer bar 10 is bolted to the top of the link 30 and the bottom of the link 30 back to the lower arm assembly 40 Since the bolt is fastened, the transverse force F1 acts in the longitudinal direction of the stabilizer bar 10 when the transverse force F1 is applied in the transverse direction and the stabilizer bar 10 is caused by the reaction force F2 against the transverse force F1. Unnecessary banding may occur and affect the bodywork.

이러한 불필요한 밴딩은 현가장치의 특성을 예기치 못한 상태로 변경시켜 차량 운동 성능의 저하시키는 문제점이 있다.Such unnecessary bending has a problem of deteriorating the vehicle movement performance by changing the characteristic of the suspension to an unexpected state.

본 발명은 상기의 결점을 해소하기 위한 것으로, 스태빌라이저 바가 롤링에 대해서만 반력을 발생시키며 횡력과 같은 다른 작용력에 대해서는 변형되지 않도록 하는 차량의 스태빌라이저 바 링크를 제공하고자 한다.SUMMARY OF THE INVENTION The present invention seeks to solve the above drawbacks, and to provide a stabilizer bar link of a vehicle such that the stabilizer bar generates a reaction force only against rolling and does not deform against other action forces such as lateral forces.

이러한 본 발명의 스태빌라이저 바 링크는 서로 힌지 체결된 제1링크와 제2링크는 양측 단부에 각각 제1및제2볼조인트가 구비됨으로써 달성된다.The stabilizer bar link of the present invention is achieved by first and second ball joints provided at both ends of the first link and the second link which are hinged to each other.

도 3 및 도 4는 본 발명의 스태빌라이저 바 링크를 보여주는 도면으로, 도 3은 본 발명의 스태빌라이저 바 링크를 보여주는 도면이며, 도 4는 본 발명의 스태빌라이저 바 링크의 작동예를 보여주는 도면이다.3 and 4 are views showing the stabilizer bar link of the present invention, Figure 3 is a view showing the stabilizer bar link of the present invention, Figure 4 is a view showing an operation example of the stabilizer bar link of the present invention.

본 발명의 실시예를 첨부 도면을 참고하여 상세히 설명하면 다음과 같다.An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 3을 참고하면, 본 발명의 스태빌라이저 바 링크(100)는 제1링크(110)와 제2링크(120)가 힌지핀(130)에 의해 힌지 체결되며, 제1링크(110)와 제2링크(120)에는 각각 제1볼조인트(111)와 제2볼조인트(121)가 구비된다.Referring to Figure 3, the stabilizer bar link 100 of the present invention is the first link 110 and the second link 120 is hinged by the hinge pin 130, the first link 110 and the second The link 120 is provided with a first ball joint 111 and a second ball joint 121, respectively.

제1볼조인트(111)는 로어암 조립체(40)에 고정되며, 제2볼조인트(121)는 스태빌라이저 바(10)에 고정된다.The first ball joint 111 is fixed to the lower arm assembly 40, and the second ball joint 121 is fixed to the stabilizer bar 10.

이와 같이 구성된 본 발명의 스태빌라이저 바 링크는 제1링크(110)와 제2링크(120)가 서로 힌지 체결되어 제1링크(110)와 제2링크(120)가 위치하는 평면 상에서 회전이 가능하다.The stabilizer bar link of the present invention configured as described above may rotate on a plane where the first link 110 and the second link 120 are hinged to each other so that the first link 110 and the second link 120 are positioned. .

또한, 제1링크(110)는 제1볼조인트(111)에 의해 로어암 조립체(40)에 체결되므로, 제1링크(110)는 로어암 조립체(40)에 대하여 입체적으로 회전이 가능하다.In addition, since the first link 110 is fastened to the lower arm assembly 40 by the first ball joint 111, the first link 110 may be three-dimensionally rotated with respect to the lower arm assembly 40.

마찬가지로 제2링크(120)는 제2볼조인트(121)에 의해 스태빌라이저 바(10)에 체결되므로, 제2링크(120)는 스태빌라이저 바(10)에 대하여 입체적으로 회전이 가능하다.Similarly, since the second link 120 is fastened to the stabilizer bar 10 by the second ball joint 121, the second link 120 may be three-dimensionally rotated with respect to the stabilizer bar 10.

이와 같이 구성된 본 발명의 스태빌라이저 바 링크의 작동예를 살펴보면 다 음과 같다.Looking at the operation example of the stabilizer bar link of the present invention configured as described above are as follows.

도 4를 참고하면, 횡력(F1)이 작용하게 되면 제1링크(110)와 제2링크(120)가 회전하면서 각도 변화가 발생하며, 또한 제1링크(110)와 제2링크(120)는 각각 차체 측과 스태빌라이저 바와 볼조인트된 부분의 요동각에 의해 횡력(F1)이 스태빌라이저 바로 전달되지 않도록 한다. 따라서, 횡력(F1)이 발생하더라도 스태빌라이저 바에는 반력이 발생되지 않으므로 종래와 같이 불필요한 밴딩이 발생되는 것을 방지한다.Referring to FIG. 4, when the lateral force F1 is applied, the angle change occurs while the first link 110 and the second link 120 rotate, and the first link 110 and the second link 120 are also rotated. The lateral force F1 is not transmitted to the stabilizer bar by the rocking angle of the body side and the stabilizer bar and the ball joint, respectively. Therefore, even when the lateral force F1 occurs, reaction force is not generated in the stabilizer bar, thereby preventing unnecessary banding from occurring.

이상과 같은 본 발명의 스태빌라이저 바 링크는 서로 힌지 체결되는 제1링크와 제2링크가 차체 및 스태빌라이저 바에 각각 볼조인트 체결되도록 구비됨으로써, 스태빌라이저 바가 롤링에 대해서만 반력을 발생시키며 다른 작용력에 대해서는 변형되지 않도록 하여 차량 운동 성능의 안정성을 향상시킬 수 있는 효과가 있는 발명인 것이다.The stabilizer bar link of the present invention as described above is provided so that the first link and the second link which are hinged to each other are ball-jointed to the body and the stabilizer bar, respectively, so that the stabilizer bar generates a reaction force only against rolling and does not deform with respect to other action forces. It is an invention that has the effect of improving the stability of the vehicle movement performance.
