Description

현가장치의 스태빌라이저 장착 구조{Structure for mounting a stabilizer of a suspension}Structure for mounting a stabilizer of suspension

본 발명은 현가장치의 스태빌라이저 장착 구조에 관한 것으로, 더욱 상세하게는 정확한 조립위치에서 스태빌라이저가 현가장치에 장착되도록 하여 원활한 스태빌라이저의 작동각을 부여하고, 그 조립시 작업성을 향상시키는 스태빌라이저 장착 구조에 관한 것이다.The present invention relates to a stabilizer mounting structure of a suspension device, and more particularly, to a stabilizer mounting structure for providing a smooth operating angle of the stabilizer by allowing the stabilizer to be mounted to the suspension device at an accurate assembly position, and improving workability during assembly. It is about.

널리 알려진 바와 같이, 차량의 현가장치는 차축과 차체를 연결하여 차량의 주행중에 차축이 노면으로부터 받는 진동이나 충격을 차체에 직접적으로 전달되지 않도록 제어하여 차체, 승객, 화물 등에 손상을 주지 않도록 하고 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.As is widely known, the suspension system of the vehicle connects the axle and the body so that the vibrations or shocks received from the road surface are not directly transmitted to the body while the vehicle is running, thereby preventing damage to the body, passengers, cargo, etc. An apparatus for improving the quality of the vehicle includes a chassis spring for mitigating an impact from a road surface, a shock absorber for controlling the free vibration of the chassis spring to improve ride quality, and a stabilizer for preventing rolling of the vehicle.

이중에서 토션바 원리를 이용한 스태빌라이저는 차량의 좌, 우측 바퀴가 각기 상하로 운동하면 스태빌라이저가 비틀리면서, 이때 발생되는 탄성력으로 차체의 기울기를 감소시켜 평형을 유지한다.Among them, the stabilizer using the torsion bar principle maintains the equilibrium by reducing the inclination of the vehicle body by the elastic force generated when the stabilizer is twisted when the left and right wheels of the vehicle move up and down, respectively.

차체의 좌, 우 양측에 장착되는 이러한 종래의 스태빌라이저의 장착 구조는 도 1에 도시된 바와 같이, 그 양쪽 선단부가 절곡된 "ㄷ" 형상의 스태빌라이저(2)의 중간 부분이 피벗 링크(19)를 통해 차체(15)에 고정되고, 체결공이 형성된 각 단부(7)가 차량의 좌, 우 양측 하부에 위치한 로어 컨트롤 암(1)에 드롭링크(3)를 통해 각각 결합고정된다.The mounting structure of the conventional stabilizer, which is mounted on both the left and right sides of the vehicle body, has a middle portion of the "c" shaped stabilizer 2 having both ends thereof bent, as shown in FIG. It is fixed to the vehicle body 15, and each end portion 7 is formed with a fastening hole is coupled to the lower control arm 1 located at the lower left and right sides of the vehicle through the drop link 3, respectively.

이러한 드롭링크(3)는 도 2에 도시된 바와 같이, 그 한쪽 부분에 형성된 볼 조인트(4)와 링크부(9)로 이루어졌다. 드롭링크(3)의 볼 조인트(4)의 나사산이 형성된 체결부(5)에 스태빌라이저(2)의 한 단부(7)가 체결되고, 링크부(9)의 단부에 형성된 나사부(6)에 로어 컨트롤 암(1, 도 1 참조)이 장착된다.This drop link 3 is composed of a ball joint 4 and a link portion 9 formed on one side thereof, as shown in FIG. One end 7 of the stabilizer 2 is fastened to the threaded fastening part 5 of the ball joint 4 of the drop link 3, and the lower part is screwed to the threaded part 6 formed at the end of the link part 9. The control arm 1 (see FIG. 1) is mounted.

하지만, 이러한 종래의 스태빌라이저 장착 구조는 조립시 스태빌라이저와 드롭링크의 볼 조인트가 서로 회전하게 되어 소정의 조립각이 발생하게 되며, 이러한 조립각은 드롭링크의 볼 조인트의 작동각을 감소시켜 볼 조인트의 이탈을 초래하는 문제점이 있었다.However, in the conventional stabilizer mounting structure, the assembly of the ball joint of the stabilizer and the drop link is rotated with each other to generate a predetermined assembly angle, and this assembly angle reduces the operating angle of the ball joint of the drop link to reduce the ball joint. There was a problem that caused the departure.

본 발명은 상기와 같은 점을 감안하여 안출한 것으로, 조립시 정확한 조립위치를 지정하여 스태빌라이저와 드롭링크의 볼 조인트가 서로 회전되는 것을 방지함으로써 볼 조인트의 작동각을 향상시키고, 또한 그에 따른 작업성을 향상시키는 스태빌라이저 장착 구조를 제공하는 데 그 목적이 있다.The present invention has been made in view of the above, by specifying the correct assembly position when assembling to prevent the ball joint of the stabilizer and the drop link is rotated with each other to improve the operation angle of the ball joint, and workability accordingly The object is to provide a stabilizer mounting structure that improves the performance of the stabilizer.
