Abstract

A stabilizer system is provided to employ two parts of a cross tube and a cross bracket to reduce the number of parts, and to remove bushes so as to reduce noise generating when bushes are abraded. A stabilizer system includes a pair of leaf spring assemblies(110), a cross tube(130), and a cross bracket(150). The leaf spring assembly includes leaf springs provided at the lower side of frames of two opposite sides of a vehicle. The cross tube has a long bar shape. The cross tube has the first end positioned at the lower end of a front surface of the left leaf spring and the second end positioned at the lower end of a front surface of the right leaf spring while extending to the right leaf spring. The cross tube serves as a stabilizer. The cross bracket couples two opposite ends of the cross tube with lower ends of the right and left leaf springs.

본 발명은 스테빌라이저 시스템에 관한 것으로서, 더욱 상세하게는 크로스 튜브를 장착하여 차량 선회시 안티-롤(Roll) 기능을 수행하며, 빠른 응답속도와 Roll강성을 향상시키는 스테빌라이저 시스템에 관한 것이다.The present invention relates to a stabilizer system, and more particularly, to a stabilizer system that is equipped with a cross tube to perform an anti-roll function when the vehicle is turned, and improves quick response speed and roll rigidity.

일반적으로 스테빌라이저는 차량의 선회시 차량이 선회 방향으로 기울어지거나 불규칙한 노면이나 바람 또는 다른 차량 등에 의해 차량이 좌우로 흔들리는 롤링(Rolling) 현상을 방지하기 위한 장치이다.In general, a stabilizer is a device for preventing a rolling phenomenon in which a vehicle is swayed left and right due to an inclination of the vehicle in a turning direction, an irregular road surface, wind, or another vehicle.

이렇게 차체가 많이 기울어지는 것을 최소화하기 위해 일반적인 차량에는 스테빌라이저(stabilizer)가 장착되어 있다.In order to minimize the inclination of the car body much, a typical vehicle is equipped with a stabilizer (stabilizer).

스테빌라이저의 양끝은 컨트롤 암에 결합되고 중앙부는 프레임에 결합되기 때문에 좌우 바퀴가 동시에 상하 운동을 하는 경우에는 작용하지 않지만, 좌우 바퀴가 서로 다른 상하 운동을 하는 경우에 작용하여 차체의 롤링 각도를 최소화한다.Since both ends of the stabilizer are connected to the control arm and the center part is connected to the frame, it does not work when the left and right wheels move up and down at the same time, but it works when the left and right wheels perform different up and down movements to minimize the rolling angle of the body. do.

첨부된 도 1은 종래의 스테빌라이저 시스템을 나타낸 사시도이다.1 is a perspective view showing a conventional stabilizer system.

도 1에 도시된 바와 같이, 스테빌라이저 시스템(30)은 로워 마운팅 브라켓(31)과, 스테빌라이저(32)와, 부시(33), 및 로드(34), 그리고 어퍼 마운팅 브라켓(35)으로 구성되어 있다.As shown in FIG. 1, the stabilizer system 30 consists of a lower mounting bracket 31, a stabilizer 32, a bush 33, a rod 34, and an upper mounting bracket 35. It is.

차량의 좌우 프레임(미도시) 하측에 각각 리프스프링(11)이 구비된 한 쌍의 리프스프링 조립체(10)가 설치된다. 각각의 리프스프링(11)을 적층시키고 U볼트(13)로 체결한다. U볼트(13)로 체결된 리프스프링(11)의 전면 하단면에 각각 로워 마운팅 브라켓(31)을 연결시키고, 스테빌라이저(32)는 부시(33)를 끼어 로워 마운팅 브라켓(31)에 장착된다.A pair of leaf spring assemblies 10 having leaf springs 11 are provided below the left and right frames (not shown) of the vehicle. Each leaf spring 11 is laminated and fastened with a U bolt 13. The lower mounting brackets 31 are respectively connected to the front lower surface of the leaf spring 11 fastened by the U bolts 13, and the stabilizer 32 is fitted to the lower mounting brackets 31 by inserting the bush 33. .

상기 로워 마운팅 브라켓(31)은 한 쌍으로 구성되는 부품으로, 평평하게 가공된 스테빌라이저(32)의 단부 양측면에 부시(33)가 끼어지고 그 부시(33)를 관통하는 2개의 볼트(미도시)와 이 볼트(미도시)에 체결되는 너트(미도시)를 매개로 고정된다.The lower mounting bracket 31 is a pair of components, and two bolts (not shown) are inserted into the bush 33 on both sides of the end of the stabilizer 32 which is flatly processed, and penetrates the bush 33. ) And a nut (not shown) fastened to the bolt (not shown).

스테빌라이저(32)의 양 타측으로 핀(미도시)을 매개로 로드(34)가 연결되었 다. 로드(34)는 차체를 가로지르는 스테빌라이저(32)의 몸체 부분을 잡아주는 스테빌라이저 로드(34)로서, 상단이 어퍼 마운팅 브라켓(35)을 매개로 차체에 고정된다.The rod 34 is connected to the other side of the stabilizer 32 via a pin (not shown). The rod 34 is a stabilizer rod 34 for holding a body portion of the stabilizer 32 across the vehicle body, and an upper end thereof is fixed to the vehicle body via the upper mounting bracket 35.

상기와 같은 구조로 스테빌라이저(32)가 장착됨으로써 스테빌라이저(32)는 양측 차륜이 동일하게 상하 거동할 때는 작용하지 않고, 양측 차륜이 상이한 거동을 보일 때는 비틀림 저항에 의해 이를 억제할 수 있도록 되어 있다.Since the stabilizer 32 is mounted in the above structure, the stabilizer 32 does not work when both wheels are equally up and down, and when the two wheels show different behavior, the stabilizer 32 can suppress it by torsional resistance. have.

이와 같은 종래의 안티-롤(Anti-Roll) 시스템의 경우, 차체와 스테빌라이저를 연결하기 위한 링크(link)구조 및 러버 부시(Rubber bush)의 적용 등으로 인해 롤(Roll) 강성의 저하 및 차량 선회시 안티-롤(Anti-Roll) 응답속도가 느려지는 단점이 있다.  In the case of such a conventional anti-roll system, due to the link structure for connecting the vehicle body and the stabilizer and the application of a rubber bush, roll stiffness decreases and the vehicle Anti-roll response speed is slow when turning.

또한 부시류의 마모에 따른 내구 성능 저하 및 잡음 문제가 발생할 가능성을 가지고 있다.In addition, there is a possibility that durability degradation and noise problems occur due to the wear of bushes.

그리고 스테빌라이저를 차체에 연결하기 위해서는 부시, 브라켓, 볼트 및 너트 등 많은 부품이 소요되기 때문에 차량의 원가상승 및 조립 작업성의 저하라는 문제점이 있다.In addition, since a large number of parts such as a bush, a bracket, a bolt, and a nut are required to connect the stabilizer to the vehicle body, there is a problem in that the cost of the vehicle is increased and the assembly workability is degraded.

본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로서, 스테빌라이저 역할을 하는 크로스 튜브를 리프스프링에 직접 연결함으로써 안티-롤(Anti-Roll) 응답속도가 향상되며, 롤 강성 손실 없이 성능을 향상시키는 스테빌라이저 시스템을 제공하는 것이다.The present invention has been made to solve the above problems, by directly connecting the cross tube acting as a stabilizer to the leaf spring to improve the anti-roll (Anti-Roll) response speed, improve performance without loss of roll rigidity It is to provide a stabilizer system.

또한 크로스 튜브와 크로스 브라켓 2가지 부품으로 구성됨으로써 부품수를 감소시키고, 부시류의 삭제를 통하여 부시 마모로 인한 내구 문제 및 잡음 등의 발생 가능성이 없으므로 부가적인 상품성을 향상시키는 스테빌라이저 시스템을 제공하는 것이다.In addition, since it consists of two parts of the cross tube and the cross bracket, the number of parts is reduced, and there is no possibility of durability problems and noise due to the wear of the bush through elimination of bushes, which provides a stabilizer system that improves the additional merchandise. will be.

상기한 목적을 달성하기 위하여, 본 발명은 차량의 양측에 설치된 프레임 하측에 길이 방향으로 각각 리프스프링이 구비된 한 쌍의 리프스프링 조립체; 긴 바(bar)의 형상으로, 일단이 상기 좌측 리프스프링 전면의 하단부에 위치하고 상기 우측 리프스프링을 향하여 연장 형성되어 타단이 상기 우측 리프스프링 전면의 하단부에 위치하며 스테빌라이저 역할을 하는 크로스 튜브; 및 상기 크로스 튜브의 양단과 상기 각각의 리프스프링의 전면의 하단부를 결합하는 크로스 브라켓을 포함하는 것을 특징으로 하는 스테빌라이저 시스템을 제공한다. In order to achieve the above object, the present invention is a pair of leaf spring assembly is provided with a leaf spring in the longitudinal direction under the frame installed on both sides of the vehicle; A cross tube having a shape of a long bar, one end of which is located at the lower end of the front side of the left leaf spring and extends toward the right leaf spring, the other end of which is located at the lower end of the front of the right leaf spring and serves as a stabilizer; And it provides a stabilizer system comprising a cross bracket for coupling both ends of the cross tube and the lower end of the front surface of each leaf spring.

상기 크로스 튜브는 원통 중공형인 것을 특징으로 한다.The cross tube is characterized in that the cylindrical hollow.

상기 크로스 튜브는 양단이 상기 크로스 브라켓에 용접 결합되는 것을 특징으로 한다.Both ends of the cross tube are welded to the cross bracket.
