Description
본 고안은 차량의 콘트롤암과 휠을 연결하는 콘트롤암 볼조인트에 관한 것으로, 더욱 상세하게는 부품수가 감소되어 제조비용이 절감되고 조립이 간단한 콘트롤암 볼조인트에 관한 것이다.The present invention relates to a control arm ball joint for connecting a control arm and a wheel of a vehicle, and more particularly, to a control arm ball joint which reduces the number of parts and reduces manufacturing costs and is simple to assemble.
일반적으로, 차량에 채용되고 있는 스트러트형 현가장치(strut type suspension)는 워시본드형(wishbone type)에 비하여 구조가 간단하고 구성부품이 적으며 정비가 용이할 뿐아니라, 스프링 하중량을 작게 할 수 있으므로 로드 홀딩 및 승차감이 우수하며, 또한 엔진 룸의 유효 공간을 넓게 할 수 있다는 장점을 갖기 때문에 최근 많은 종류의 승용차에 사용되고 있다.In general, the strut type suspension employed in vehicles has a simpler structure, fewer components, easier maintenance, and a lower spring load than the washbone type. Therefore, it has been used in many kinds of passenger cars recently because it has an advantage of excellent road holding and riding comfort and wider effective space of the engine room.
이러한 스트러트형 현가장치는 조향 너클(knucle)과 일체로 형성되고 쇽 업서버(shock absorber)가 내장되어 있는 스트러트, 현가 콘트롤 암, 콘트롤 암과 스트러트 하부를 연결하는 볼 조인트 및 스프링 등으로 구성되어 있으며, 스트러트의 상부는 현가 서포트를 거쳐서 차쳬에 결합되고, 현가 서포트에는 스러스트 베어링이(thrust bearing) 삽입되어 스트러트가 자유로이 회전할 수 있게 됨으로써 조향작용이 되도록 되어 있다.This strut-type suspension is composed of a strut that is integrally formed with a steering knucle and has a shock absorber, a suspension control arm, a ball joint and a spring connecting the control arm and the lower part of the strut. The upper part of the strut is coupled to the wheel via the suspension support, and a thrust bearing is inserted into the suspension support to allow the strut to rotate freely, thereby allowing steering.
그리고, 코일스프링은 스트러트와 스프링 시트와의 사이에 결합되고 스프링 시트는 현가 서포트의 스러스트 베어링에 접하고 있으며, 차량의 중량은 현가 서포트를 거쳐서 차쳬에 작용되도록 되어 있다.The coil spring is coupled between the strut and the spring seat, the spring seat is in contact with the thrust bearing of the suspension support, and the weight of the vehicle is acted on the vehicle gradually through the suspension support.
즉, 콘트롤암의 일단부에는 콘트롤암 볼조인트가 체결되고, 콘트롤암 볼조인트에 조향 너클이 결합되어 있으며, 조향 너클의 지축에 프론트 스프링을 가지는 쇽 업소버가 결합되어 있다.That is, a control arm ball joint is fastened to one end of the control arm, a steering knuckle is coupled to the control arm ball joint, and a shock absorber having a front spring is coupled to the axis of the steering knuckle.
콘트롤암에는 프론트 스테빌라이저가 축에 의해 연결되어 있고, 상기 축의 양단부, 즉 콘트롤암과 프론트 스테빌라이저에 결합되는 상,하단 결합부에는 범퍼가 결합되어 있으며, 상기 조향 너클에는 휠이 결합되어 있다.A front stabilizer is connected to the control arm by a shaft, and upper and lower coupling parts coupled to both ends of the shaft, that is, the control arm and the front stabilizer, are coupled to bumpers, and a wheel is coupled to the steering knuckle.
그리고, 콘트롤암 볼조인트는 그의 조인트가 콘트롤암의 연결단부에 보울트와 너트로 체결된 구성으로 되어 있다.The control arm ball joint has a structure in which its joint is fastened with a bolt and a nut at the connection end of the control arm.
볼조인트는 도 3에 도시된 바와 같이, 하우징(121)과, 하우징(121)에 수용되어 하우징(121)의 내표면과 슬라이딩 접촉하는 볼(125), 하우징(121)의 저부면에 설치되어 볼(125)과 직접 접촉하게 되는 수지재질로 만들어진 지지부재(126) 및 지지부재(126)의 하부에 설치되어 상기 볼(125)을 탄성적으로 지지하는 스프링와셔(127) 등으로 이루어져 있다.As shown in FIG. 3, the ball joint is installed in the housing 121, the ball 125 accommodated in the housing 121, and in contact with the inner surface of the housing 121, and the bottom surface of the housing 121. The support member 126 is made of a resin material which is in direct contact with the ball 125 and the spring washer 127 is installed on the lower portion of the support member 126 to elastically support the ball 125.
그래서, 이와 같은 스트러트형 현가장치는 저면에서 올라오는 하중을 콘트롤암 볼조인트(120)로 받고 있기 때문에, 볼조인트(120)의 볼(125)이 지지부재(126)와 마찰접촉하면서 스프링와셔(127)에 의해 탄성적으로 지지된다.Therefore, since such a strut type suspension device receives the load from the bottom surface by the control arm ball joint 120, the ball 125 of the ball joint 120 is in frictional contact with the support member 126 while the spring washer ( 127 is elastically supported.
그런데, 종래의 이러한 볼조인트(120) 구조에서는, 지지부재(126) 및 스프링와셔(127)의 이중지지구조가 채용됨으로써, 부품수 증가에 따라서 제조비용의 상승하고 조립상 불편하다는 문제점이 있었다.By the way, in the conventional ball joint structure 120, the double support structure of the support member 126 and the spring washer 127 is adopted, there is a problem that the manufacturing cost increases with the increase in the number of parts and assembly inconvenience.
이에 본 고안은 상기한 바와 같은 종래의 결함 및 문제점을 해결하기 위하여 안출된 것으로, 부품수가 감소되어 제조비용이 절감되고 조립이 간단한 콘트롤암 볼조인트를 제공함에 그 목적이 있다.The present invention has been made to solve the above-mentioned defects and problems as described above, the object of the present invention is to provide a control arm ball joint is reduced in the number of parts reduced manufacturing cost and simple assembly.
상기와 같은 목적을 달성하기 위한 본 고안은, 차량의 콘트롤암과 휠을 연결하는 콘트롤암 볼조인트에 있어서, 하우징과, 하우징에 수용되어 하우징의 내표면과 슬라이딩 접촉하는 볼과, 하우징의 저부면에 설치되어 볼을 탄성지지하는 탄성수지를 포함하는 것을 특징으로 하는 콘트롤암 볼조인트에 의해 달성된다.The present invention for achieving the above object, in the control arm ball joint connecting the control arm and the wheel of the vehicle, the housing, the ball accommodated in the housing and sliding contact with the inner surface of the housing, the bottom surface of the housing It is achieved by a control arm ball joint, characterized in that it comprises an elastic resin installed in the elastic support for the ball.
이에 따라, 종래에 채용되던 스프링와셔가 배제되어 부품수 감소에 따라 제조비용이 절감되고 조립이 간단해지게 된다.Accordingly, the spring washer that has been conventionally employed is excluded, and as the number of parts is reduced, manufacturing cost is reduced and assembly is simplified.

이하 본 고안을 첨부한 예시도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings of the present invention as follows.
도 1 는 본 고안에 따른 콘트롤암 볼조인트가 설치된 스트러트형 현가장치의 종단면도이고, 도 2 는 도 1의 콘트롤암 볼조인트의 확대단면도이다. 이들 도면에 도시된 바와 같이, 콘트롤암(10)의 일단부에는 콘트롤암 볼조인트(20)가 체결되고, 콘트롤암 볼조인트(20)에 조향 너클(30)이 결합되어 있으며, 조향 너클(30)의 지축(31)에 프론트 스프링을 가지는 쇽 업소버(40)가 결합되어 있다.1 is a longitudinal cross-sectional view of a strut type suspension device in which a control arm ball joint is installed according to the present invention, and FIG. 2 is an enlarged cross-sectional view of the control arm ball joint of FIG. 1. As shown in these figures, the control arm ball joint 20 is fastened to one end of the control arm 10, the steering knuckle 30 is coupled to the control arm ball joint 20, and the steering knuckle 30 The shock absorber 40 having a front spring is coupled to the support shaft 31 of ().
쇽 업소버(40)의 인접한 지점에서는 프론트 스테빌라이저가 축에 의해 상기 콘트롤암(10)과 연결되고, 상기 축의 양단부, 즉 콘트롤암(10)과 프론트 스테빌라이저에 결합되는 상,하단 결합부에는 범퍼가 결합되어 있으며, 상기 조향 너클(30)에는 휠(70)이 결합되어 있다.인접한 At adjacent points of the absorber 40, the front stabilizer is connected to the control arm 10 by a shaft, and the upper and lower coupling portions coupled to both ends of the shaft, that is, the control arm 10 and the front stabilizer, are bumpers. Is coupled, and the wheel 70 is coupled to the steering knuckle 30.
한편, 볼조인트(20)는 하우징(21)과, 하우징(21)에 수용되어 하우징(21)의 내표면과 슬라이딩 접촉하는 볼(25)과, 하우징(21)의 저부면에 설치되어 볼(21)을 탄성지지하는 탄성수지(26)로 이루어져 있다.On the other hand, the ball joint 20 is provided in the housing 21, the ball 25 accommodated in the housing 21 and sliding contact with the inner surface of the housing 21, and the ball joint 20 is provided on the bottom surface of the housing 21 21 is made of an elastic resin 26 to elastically support.
여기서, 탄성수지(26)는 소정의 탄성력을 가지고 볼(21)을 탄성적으로 지지하게 됨에 따라, 종래에 채용되던 스프링와셔가 별도로 장착되지 않더라고 볼(21)이 지지될 수 있게 되어 있다.Here, as the elastic resin 26 elastically supports the ball 21 with a predetermined elastic force, the ball 21 can be supported even if the spring washer that is conventionally employed is not separately mounted.
이에 따라, 종래에 채용되던 스프링와셔가 배제되어 부품수 감소에 따라 제조비용이 절감되고 조립이 간단해지게 된다.Accordingly, the spring washer that has been conventionally employed is excluded, and as the number of parts is reduced, manufacturing cost is reduced and assembly is simplified.
이상에서 설명한 바와 같은 본 고안에 따른 콘트롤암 볼조인트(20)에 의하면, 부품수가 감소되어 제조비용이 절감되고 조립이 간단하게 되는 효과가 있게 된다.According to the control arm ball joint 20 according to the present invention as described above, there is an effect that the number of parts is reduced to reduce the manufacturing cost and to simplify the assembly.
