Abstract
본 고안은 자동차용 트레일링 링크(Trailing Link)의 부싱(Bushing)에 관한 것으로서, 좀더 구체적으로는 양측의 부싱을 지지하는 레터럴 로드가 외부 일측에 고정되는 외통(4)과, 상기 외통(4)의 내측에 형성되어 토인성을 부여하는 고무(3)와, 상기 고무(3)를 지지시켜주는 인너파이프(1)로 구성된 트레일링 링크의 부싱에 있어서, 상기 인너파이프(1)의 외측에 나선형의 리브(2)를 형성하여 현가장치의 횡력입력(선회시)에 대한 강성증대와 함께 외후륜에 토인성을 부여하여 언더 스티얼링을 높여주어 운전자가 선회하고자 할때 차량의 한계 선회속도를 증가시킬 수 있게 되고, 선회 안정성을 증대시킬 수 있게 한 것이다.The present invention relates to a bushing of a trailing link for a vehicle, and more specifically, an outer cylinder 4 in which a lateral rod supporting both bushings is fixed to an outer side, and the outer cylinder 4 In the bushing of the trailing link formed of a rubber (3) formed inside the c) to impart torsion, and an inner pipe (1) supporting the rubber (3), on the outside of the inner pipe (1). Spiral ribs (2) are formed to increase the rigidity of the lateral force input (when turning) of the suspension system, and provide torsional resistance to the rear wheels to increase the under-steering to increase the limit turning speed of the vehicle when the driver wants to turn. It is possible to increase, and to increase the swing stability.
Description
일반적으로 자동차의 타이머에 캠버를 두었을때 발생하는 측방의 힘을 상쇄시키기 위하여 이용되는 토인은 조향바퀴의 사이드 슬림과 타이머 마멸을 방지하고 앞바퀴를 평행하게 회전시키며 링키지 마멸에 의한 토아웃(Toe-out)됨을 방지하기 위해서 사용된다.In general, the toe used to offset the lateral force generated when the camber is placed on the timer of the car prevents side slim and timer wear of the steering wheel, rotates the front wheel in parallel, and toe-out by linkage wear. Used to prevent out).
그리고 트레일링 리크가 듀얼링크(Dual Link)식 현가장치에서 로우어 링크(Lower Link)중 하나가 장착되는 후륜현가장치 구조의 트레일링 링크 부싱은 도 1에 도시된 바와 구성되어 있어 부시가 좌우로 미끄러지는 현상을 방지할 수 있으나 트레일링 링크 링크의 회전시 부시의 찌그러짐 등과 같은 기구학적인 변화에 의한 차륜의 변화를 수동적으로 받아들이게 되어 차륜의 토인성향을 부시고무의 경도 및 고무형상으로 조절하게 된다.In addition, the trailing link bushing of the rear suspension structure in which the trailing leak is mounted in one of the lower links in the dual link suspension is configured as shown in FIG. The sliding phenomenon can be prevented, but when the trailing link is rotated, the wheel change due to the kinematic change such as the crushing of the bush is manually received, thereby adjusting the toe tendency of the wheel to the hardness and rubber shape of the bush rubber.
즉, 종래의 트레일링 링크의 부싱은 도 1과 같이 중앙부에 돌기(6)가 돌출된 인너파이프(5)와, 상기 인너파이프(5)의 외측에 형성된 고무(3)와, 상기 고무(3)의 외측에 형성되고 레터럴 로드(7)가 고정된 외통(4)으로 구성되어 있다.That is, the bushing of the conventional trailing link includes an inner pipe 5 having a protrusion 6 protruding from the center as shown in FIG. 1, a rubber 3 formed outside the inner pipe 5, and the rubber 3. The outer cylinder 4 is formed on the outer side and the lateral rod 7 is fixed.
따라서 인너파이프(5)의 돌기(6)에 의해 부시가 미끄러지는 현상은 없으나 트레일링 링크의 회전시 차륜의 변화를 수동적으로 받아들이게 되어 현가장치의 선회에 대한 강성이 저하되었고, 외후륜에 토인성향이 잘 부여되지 않아 언더 스티얼(Under Steer)성이 저하되어 운전자가 차량을 선회하고자 할때 차량의 한계 선회속도가 낮게 도어 선회 안정성이 저하되었다.Therefore, there is no sliding of the bush by the projection 6 of the inner pipe 5, but the change of the wheel is passively accepted when the trailing link is rotated, so that the rigidity of the suspension of the suspension is lowered, and the propensity to toin the outer wheel Due to this poor understeer performance, the door turning stability was lowered when the driver tried to turn the vehicle with a lower limit turning speed.
즉, 종래의 부싱은 차량의 선회시 외후륜은 범프(Bump)하면서 휠 스트로크(Wheel Stroke)가 30-50이상 부터의 토아웃성을 띠려 하기 때문에 과다선회시 외측륜이 토아웃성을 띠게 되면 순간적으로 오버스티얼(Over Steer)로 가는 성향이 생길 뿐만 아니라 차륜의 접지력이 저하되어 선호 안정성이 저하되는 등의 문제가 있었다.That is, in the conventional bushing, when the outer wheel is bumped while the vehicle is turning, the wheel stroke is toned out from 30-50 or more. At the moment, there is a problem that the tendency to go to over steer is not only generated, but the grip power of the wheel is lowered, and thus the preferred stability is lowered.
따라서 본 고안은 상기와 같은 제반 문제점을 제거하기 위하여 안출된 것으로서 부싱의 인너파이프 외측에 나선형 리브를 형성시켜 현가장치의 선회에 대한 강성을 증대시키고, 외후륜에 토인 성향을 부여하여 언더 스티얼성을 높여주어 차량의 한계 선회속도를 향상시키는데 고안의 목적이 있다.Therefore, the present invention was devised to eliminate the above-mentioned problems. As a spiral rib is formed outside the inner pipe of the bushing, the rigidity against the turning of the suspension system is increased, and the understeer property is imparted to the outer wheel by giving a ton tendency. The purpose is to improve the limit turning speed of the vehicle by raising.
상기 목적을 달성하기 위한 본 고안의 특징은 레터럴 로드가 일측에 고정된 외통과, 상기 외통의 내부에 내장되어 토인성을 부여하는 고무와, 상기 고무를 지지하는 인너파이프로 구성된 트레일링 링크 부싱에 있어서, 상기 인너파이프의 외측에 나선형 리브를 형성한 구조로 된 것이다.Features of the present invention for achieving the above object is a trailing link bushing consisting of an outer cylinder fixed to one side of the lateral rod, a rubber embedded in the outer cylinder to give torsion, and an inner pipe for supporting the rubber In the structure, the spiral pipe is formed outside the inner pipe.

이하 첨부된 도면에 의거하여 본 고안의 구성 및 작용을 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 고안에 의한 트레일링 링크의 부싱을 나타낸 것으로서, (가)는 인너파이프의 사시도를 나타낸 것이고, (나)는 부싱의 전체 단면도로서 도면 부호중 1은 인너파이프, 2는 나선형리브, 3은 고무, 4는 외통을 나타낸 것이다.Figure 2 shows the bushing of the trailing link according to the present invention, (A) is a perspective view of the inner pipe, (B) is a full cross-sectional view of the bushing 1 of the inner pipe, 2 is a spiral rib, 3 represents rubber and 4 represents an outer cylinder.
도시된 바와 같이 양측의 부싱을 지지하는 레터럴 로드가 외부 일측에 고정되는 외통(4)과, 상기 외통(4)의 내측에 형성되어 토인성을 부여하는 고무(3)와, 상기 고무(3)를 지지시켜주는 인너파이프(1)로 구성된 트레일링 링크의 부싱에 있어서, 상기 인너파이프(1)의 외측에 나선형의 리브(2)를 형성한 것으로서, 인너파이프(1)의 오른쪽과 왼쪽의 나선형리브(2)의 기울기(α°)는 서로 대칭되게 실시한다.As shown, a lateral rod 4 supporting the bushings on both sides is fixed to an outer side, a rubber 3 formed inside the outer cylinder 4 to impart torsion, and the rubber 3 In the bushing of the trailing link consisting of the inner pipe (1) supporting the (1), a spiral rib (2) formed on the outside of the inner pipe (1), the right and left of the inner pipe (1) The inclination α of the helical ribs 2 is performed symmetrically with each other.
이와 같은 본 고안은 서스펜션 구조뿐만 아니라 모든 트레일링 링크의 부싱에도 적용하여 실시할 수 있는 것이다.This invention can be applied to the bushings of all trailing links as well as the suspension structure.
이상과 같은 본 고안은 트레일링 링크의 회전이 발생할 때 나선형 리브(2)의 나선각(α°)을 따라 트레일링 링크를 움직여 주며, 이의 선정은 차량 선회안정성을 위주로 할 경우 범프시 내측방향, 리바운드시 외측으로 움직이게 하면 외,후륜의 트레일링 링크과 로우어 링크간의 각이 작아지는 방향이 되어 현가장치의 횡력입력(선회시)에 대한 강성증대와 함께 외후륜에 토인성을 부여하는 언더 스티얼성을 높여주어 운전자가 선회하고자 할때 차량의 한계 선회속도를 증가시킬 수 있게 되고, 선회 안정성을 증대시킬 수 있는 효과가 있는 것이다.The present invention as described above moves the trailing link along the helix angle (α °) of the spiral rib (2) when the trailing link is rotated, the selection of the inner direction when bumping, if the focus on the vehicle turning stability When moving outward during rebound, the angle between the trailing link and the lower link of the outer and rear wheels becomes smaller, which increases the stiffness of the lateral force input (when turning) and gives the torsional resistance to the rear wheels. When the driver wants to turn to increase the vehicle's limit turning speed is increased, it is effective to increase the turning stability.
본 고안은 자동차용 트레일링 링크(Trailing Link)의 부싱(Bushing)에 관한 것으로서, 좀더 구체적으로는 부싱의 인너파이프(Inner Pipe)의 외부에 나선형 리브(Spiral형 Rib)를 형성시켜 현가장치(Suspension)의 횡력입력에 대한 강성을 증대시키고, 외후륜에 대한 토인(Toe-in)성향을 부여하여 선회안정성을 향상시킨 자동차의 트레일링 링크 부싱에 관한 것이다.The present invention relates to a bushing of a trailing link for a vehicle. More specifically, a suspension rib is formed by forming a spiral rib outside the inner pipe of the bushing. The present invention relates to a trailing link bushing of an automobile which improves turning stability by increasing the rigidity of the lateral force input and giving a toe-in tendency to the outer and rear wheels.
