Description

차량의 현가장치의 스태빌라이저 바와 댐퍼의 결합구조{Connecting Structure between stabilizer bar and damper of suspension system of vehicle}Connecting structure between stabilizer bar and damper of suspension system of vehicle

본 발명은 차량의 현가장치의 스태빌라이저 바와 댐퍼의 결합구조에 관한 것으로서, 보다 상세하게는 차량의 현가장치를 구성하는 댐퍼 또는 로어암을 스태빌라이저 단부가 직접 면접촉 상태로 지지하여 차량의 진동을 흡수 및 분산시켜 억제 또는 상쇄시킬 수 있는 차량의 현가장치의 스태빌라이저 바와 댐퍼의 결합구조에 관한 것이다.The present invention relates to a coupling structure of a stabilizer bar and a damper of a suspension of a vehicle, and more particularly, a damper or a lower arm constituting the suspension of a vehicle is supported by the stabilizer end in direct surface contact to absorb vibration of the vehicle. The present invention relates to a coupling structure of a stabilizer bar and a damper of a suspension of a vehicle that can be dispersed and suppressed or canceled.

일반적으로, 차량에는 차축과 차체를 연결하여 주행중에 노면으로부터 받는 진동이나 충격이 차체에 직접 전달되지 않도록 하기 위해 현가장치가 구비되어 있다. 이 같은 현가장치에 의해 차체와 화물의 손상이 방지됨은 물론 승차감이 향상되는 것이다.In general, the vehicle is provided with a suspension device in order to connect the axle and the vehicle body so that vibrations or shocks received from the road surface during driving are not directly transmitted to the vehicle body. Such suspension prevents damage to the body and cargo, as well as improving ride comfort.

이 같은 현가장치는 도 1에 도시된 바와 같이, 로어암(1)에 후단부가 전후 부시에 의해 결합되고 선단부에는 상하부시(2)가 설치된 텐션로드(3)와, 그 텐션로드(3)의 선단부가 고정되게 차체(도시않됨)에 고정되도록 로드에 의해 차체에 설치되는 브라켓(4)과, 그 브라켓(4)에 좌우 양측부가 지지되고 중앙부에는 프레임에 결합되며 좌우 양측단부는 댐퍼(5)에 결합된 스태빌라이저(6)로 이루어져 있다.As shown in FIG. 1, the suspension device includes a tension rod 3 having a rear end coupled to the lower arm 1 by a front and rear bush, and an upper and lower bushes 2 installed at the front end thereof, and the tension rod 3. A bracket 4 installed on the vehicle body by a rod so that the front end portion is fixed to the vehicle body (not shown), the left and right both sides are supported by the bracket 4, the center portion is coupled to the frame, and the left and right both ends are dampers 5 It consists of a stabilizer (6) coupled to.

이 같은 구성에 따라, 차량의 운행 중 전후 및 상하로 충격이 발생하는 경우에는 텐션로드(3)가 충격에 의해 발생되는 충격에너지를 효과적으로 흡수 및 차체로 분산시키게 되며, 좌우양측으로 충격이 발생하는 경우에는 스태빌라이저가 충격에 의해 발생된 충격에너지를 흡수 및 분산시켜 승객의 승차감 및 차량의 안전성이 향상될 수 있는 것이다.According to such a configuration, when the impact occurs before and after and up and down during the driving of the vehicle, the tension rod 3 effectively absorbs the impact energy generated by the impact and disperses it to the vehicle body, and the impact occurs to the left and right sides. In this case, the stabilizer may absorb and disperse the impact energy generated by the impact, thereby improving passenger comfort and vehicle safety.

그러나 이와 같은 종래의 현가장치는 다소의 문제점이 있는 것으로 나타났다. 먼저, 바퀴의 좌우 운동을 역학적으로 연결하는 스태빌라이저에서는 연결부분의 자유로운 운동이 발생하므로 고가의 볼조인트를 필요로 하게 되어 원가가 비싸지는 문제점이 있다.However, such a conventional suspension device appeared to have some problems. First, in the stabilizer for dynamically connecting the left and right movements of the wheels, free movement of the connection portion occurs, which requires expensive ball joints, which causes a problem of high cost.

그리고, 내구성 및 응답성에 문제가 발생할 수 있는 부시가 적용되는 콘트롤링크가 필수적으로 요구되어 구조가 복잡해지는 문제점이 있다.In addition, a control link to which a bush is applied, which may cause a problem in durability and responsiveness, is essentially required, resulting in a complicated structure.

이에 본 발명은 상술된 문제점들을 해결하기 위해 발명된 것으로서, 본 발명의 목적은 응답성이 향상되고 뛰어난 주행 안정성을 확보할 수 있는 차량의 현가장치의 스태빌라이저와 댐퍼의 결합조를 제공하는데 있다.Accordingly, the present invention has been invented to solve the above-described problems, and an object of the present invention is to provide a coupling tank of a stabilizer and a damper of a suspension device of a vehicle capable of improving responsiveness and ensuring excellent driving stability.

본 발명의 다른 목적은 구조가 간단하고 조립성, 정비성, 작업성이 우수한 차량의 현가장치의 스태빌라이저와 댐퍼의 결합구조를 제공하는데 있다.Another object of the present invention is to provide a combined structure of a stabilizer and a damper of a suspension device of a vehicle having a simple structure and excellent assembly, maintenance and workability.

본 발명의 또 다른 목적은 제조원가가 절감되고, 부품의 가공이 불필요하여 경량화될 수 있는 차량의 현가장치의 스태빌라이저와 댐퍼의 결합구조를 제공하는데 있다.Still another object of the present invention is to provide a combined structure of a stabilizer and a damper of a suspension device of a vehicle, which can reduce manufacturing cost and can be made lightweight due to unnecessary machining of parts.

특히, 본 발명에 따른 결합구조가 적용되는 스태빌라이저 바(10)의 굴곡형성된 일측의 단부에는 결합구(18)가 일체로 형성된다. 그 결합구(18)는 볼록형으로 형성되며 특히 반구형으로 형성되는 것이 바람직하다.In particular, the coupling sphere 18 is integrally formed at one end of the bent side of the stabilizer bar 10 to which the coupling structure according to the present invention is applied. The coupler 18 is formed in a convex shape, particularly preferably in a hemispherical shape.

또한, 본 발명에 따른 결합구조가 적용되는 로어암 또는 댐퍼(20)는 기본적으로 차체에 고정되는 몸체(22)와 그 몸체(22)를 완충적으로 유지하기 위한 스프링(24)을 포함한다.In addition, the lower arm or damper 20 to which the coupling structure according to the present invention is applied includes a body 22 fixed to the vehicle body and a spring 24 for buffering the body 22.

특히, 댐퍼(20)의 몸체(22)의 하단에는 전술된 스태빌라이저 바(10)의 결합구(18)가 밀착적으로 면접촉을 이루어 결합되는 수용홈(26)이 형성된다. 이 수용홈(26)은 물론 스태빌라이저 바(10)가 허용된 범위내에서 최대로 운동하는 경우에도 그 단부에 형성된 결합구(18)가 수용홈(26)에서 이탈되는 것을 방지할 수 있도록 충분한 깊이를 갖는 것이 바람직하다.In particular, the lower end of the body 22 of the damper 20 is formed with an accommodating groove 26 in which the coupling hole 18 of the stabilizer bar 10 described above is in close contact with each other. This accommodation groove 26, of course, is deep enough to prevent the coupler 18 formed at its end from leaving the accommodation groove 26 even when the stabilizer bar 10 is maximally moved within the permitted range. It is preferable to have.

결과적으로, 본 발명에 따른 스태빌라이저 바와 댐퍼의 결합구조에 의하면, 종래의 현가장치를 구성하는 콘트롤링크, 볼조인트, 부시, 와셔, 볼트, 너트, 커버, 그리스 등이 생략되는 현가징치를 이룰 수 있는 것이다.As a result, according to the coupling structure of the stabilizer bar and the damper according to the present invention, it is possible to achieve a suspension value in which the control link, ball joint, bush, washer, bolt, nut, cover, grease, etc. constituting the conventional suspension device are omitted. will be.

이하, 본 발명에 따른 스태빌라이저 바와 댐퍼의 결합방식 및 그 작용모드에 대해 상세히 설명한다.Hereinafter, the coupling method and the operation mode of the stabilizer bar and the damper according to the present invention will be described in detail.

먼저, 작업자는 스태빌라이저 바(10)를 차량의 하부차체를 구성하는 서브프레임(14)을 장착한다. 이 때, 작업자는 스태빌라이저 바(10)의 단부에 형성된 결합구(18)가 댐퍼(20)의 최대 범프위치, 즉 댐퍼(20)가 하방으로 최대로 이동한 위치에 이른 상태에서 스태빌라이저 바(10)의 결합구(18)를 댐퍼(20)의 수용홈(26)에 삽입하여 결합시킨다.First, the worker mounts the stabilizer bar 10 into the subframe 14 constituting the undercar body of the vehicle. At this time, the operator is stabilizer bar 10 in the state that the coupling hole 18 formed at the end of the stabilizer bar 10 has reached the maximum bump position of the damper 20, that is, the position where the damper 20 is moved downwards to the maximum. The coupling hole 18 of the) is inserted into the receiving groove 26 of the damper 20 to be coupled.

이에 따라, 스태빌라이저 바(10)의 본체(16)에는 탄성력 또는 스프링력이 인가되며, 결과적으로 스태빌라이저(10)와 댐퍼(20)는 상호 탄성적이며 완충적인 결합 관계가 유지되는 것이다.Accordingly, an elastic force or a spring force is applied to the main body 16 of the stabilizer bar 10, and as a result, the stabilizer 10 and the damper 20 maintain a mutually elastic and cushioning coupling relationship.

이와 같은 스태빌라이저 바와 댐퍼의 결합구조를 갖는 차량이 운행중에 노면 또는 외부로부터 휠에 충격이 가해지면 그 충격이 댐퍼(20)의 몸체(22) 및 스프링(24)에 의해 일부가 완충되며, 나머지는 몸체(22)의 하단의 수용홈(26)에 면접촉되는 결합구(18)를 통해 스태빌라이저 바(10)의 몸체(16)로 전달된다. 이와 같이 스태빌라이저 바(10)의 몸체(22)로 전달된 충격력은 스태빌라이저 바(10)의 반대편에 연계된 휠(도시안됨)로 전달되어 상쇄됨으로써, 그 충격이 완화되는 것이다.If a vehicle having such a structure of a stabilizer bar and a damper is applied to the wheel while driving, the shock is partially buffered by the body 22 and the spring 24 of the damper 20, and the rest is It is transmitted to the body 16 of the stabilizer bar 10 through the coupler 18 which is in surface contact with the receiving groove 26 of the lower end of the body 22. As such, the impact force transmitted to the body 22 of the stabilizer bar 10 is transmitted to and offset by a wheel (not shown) connected to the opposite side of the stabilizer bar 10, thereby alleviating the impact.

이에 따라, 간단하게 스태빌라이저 바와 댐퍼의 면접촉 결합에 의해 휘로부터 전달되는 다양한 방향의 충격을 상쇄 및 완화시킬 수 있는 것이다.Accordingly, it is possible to simply cancel and mitigate the impact in various directions transmitted from the wheel by the surface contact coupling of the stabilizer bar and the damper.

결과적으로, 본 발명에 따른 스태빌라이저 바와 댐퍼의 결합구조에 의하면, 스태빌라이저 바와 댐퍼가 직접 면접촉을 이루고 또한 탄성적으로 결합됨으로써, 간단한 구조로 충격을 효과적으로 상쇄 및 흡수할 수 있어 제품성 및 신뢰성이 향상되는 효과가 있다.As a result, according to the coupling structure of the stabilizer bar and the damper according to the present invention, the stabilizer bar and the damper is in direct surface contact and elastically coupled, so that the impact can be effectively canceled and absorbed with a simple structure, thereby improving productability and reliability. It is effective.

또한, 스태빌라이저 바와 댐퍼가 직접 결합되므로 응답성이 향상되고 뛰어난 주행 안정성을 확보할 수 있으며, 구조가 간단하여 조립성, 정비성, 작업성이 우수한 장점이 있다.In addition, since the stabilizer bar and the damper are directly coupled to each other, the response can be improved and excellent driving stability can be secured. The structure is simple, and thus the assembly, maintenance and workability are excellent.

이상에서 본 발명에 따른 바람직한 실시예에 대해 설명하였으나, 본 기술분야의 당업자라면 첨부된 특허청구범위를 벗어남이 없이 다양한 변형예 및 수정예를 실시할 수 있을 것으로 이해된다.While a preferred embodiment according to the present invention has been described above, it will be understood by those skilled in the art that various modifications and changes can be made without departing from the scope of the appended claims.
