이하 본 발명의 실시예에 따른 구성 및 작용을 첨부 도면에 따라 보다 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명의 구성을 보인 분해 사시도이고, 도 3과, 도 4는 본 발명의 조립 상태를 보인 평단면도와 정단면도이다.Figure 2 is an exploded perspective view showing the configuration of the present invention, Figure 3 and Figure 4 is a plan sectional view and a front sectional view showing the assembled state of the present invention.
도면에서 보듯이 본 발명은 튜브 조인트(2)의 끝단에 형성한 홀더부(20)와, 샤프트 조인트(1)의 끝단에 형성한 볼부재(10), 그리고 핀스톱퍼(6)와, 서포트부재(5)로 이루어 진다.As shown in the drawings, the present invention provides a holder 20 formed at the end of the tube joint 2, a ball member 10 formed at the end of the shaft joint 1, a pin stopper 6, and a support member. It is made of (5).
상기한 튜브 조인트의 홀더부(20)는 내면이 반구형으로 이루어지며, 그 중단 양측에서 한쌍의 관통구멍(22)이 형성되고, 내경에 암나사(23)가 형성된 것이고, 샤프트 조인트(1)의 볼부재(10)는 오일리스 프라스틱재로써 상기 샤프트 조인트(1) 끝단이 끼워지도록 인서트 몰딩의 방법으로 성형하되, 가로로 가이드홈(12)이 형성된 채 상기 홀더부의 속에 끼워질 것이다.The holder portion 20 of the tube joint has a hemispherical inner surface, and a pair of through holes 22 are formed at both ends of the tube joint, and a female screw 23 is formed at an inner diameter thereof, and a ball of the shaft joint 1 is formed. The member 10 is molded by insert molding so that the end of the shaft joint 1 is fitted with an oilless plastic material, but is inserted into the holder part with the guide groove 12 formed horizontally.
그리고 인서트 몰딩을 하되, 결속력을 높이기 위해 상기한 샤프트 조인트(1)의 끝단에 다수의 구멍(13)을 형성하여, 몰딩되는 플라스틱이 상기 구멍으로 일부 침투하도록 되는 것이다.And while insert molding, to form a plurality of holes 13 in the end of the shaft joint (1) in order to increase the binding force, the plastic to be molded is to partially penetrate the hole.
또, 상기 볼부재(10)의 이탈을 방지하기 위한 서포트부재(5)는 오일리스 플라스틱재의 받침링(52)과, 받침링의 바깥쪽에서 나삽할 나사링(51)으로 이루어 지며, 상기한 홀더부(20)의 양측 관통구멍(22)에는 좌우측에서 핀스톱퍼(6)를 끼워 조립한다.In addition, the support member 5 for preventing separation of the ball member 10 is composed of a support ring 52 of the oilless plastic material, and a screw ring 51 to be inserted from the outside of the support ring, the holder Both side through holes 22 of the part 20 are assembled with pin stoppers 6 on the left and right sides.
한편, 상기한 서포트부재(5)의 나사링(51)은 그 외주면 일측에 나사산이 형성되지 않은 불완전 나사부(51a)를 형성하여 풀림이 방지되도록 하는 것이 좋으며, 경우에 따라서는 합성수지 도포층(51b)을 형성하여 풀림이 방지되도록 할 수도 있다.On the other hand, the screw ring 51 of the support member (5) is preferably formed on the outer peripheral surface of the incomplete threaded portion (51a) is not formed by the thread to prevent loosening, in some cases synthetic resin coating layer (51b) ) May be formed to prevent loosening.
이상과 같이 구성된 본 발명은 상측 샤프트 조인트(1)로부터 하측 튜브 조인트(2)로 조향장치의 회전력을 전달함에 있어서, 상측 샤프트 조인트(1)와 하측 튜브 조인트(2)가 도 3에서 보듯이 가로 방향으로 회동할 수 있고, 도 4에서 보듯이 상,하 방향으로도 회동할 수 있기 때문에 유니버셜 조인트로서의 기능을 충분히 발휘할 수 있는 것이다.In the present invention configured as described above, the upper shaft joint 1 and the lower tube joint 2 are transverse as shown in FIG. 3 in transmitting the rotational force of the steering apparatus from the upper shaft joint 1 to the lower tube joint 2. Direction can be rotated, and as shown in Fig. 4 can also be rotated in the up and down direction, it is possible to fully exhibit the function as a universal joint.
즉, 도 3에서 보듯이 홀더부(20)의 양쪽 관통구멍(22)에 끼운 핀스톱퍼(6)는 볼부재(10)가 수평방향으로 회동할때는 가이드홈(12)을 따라 이동하여 흔들림이 없도록 하고, 수직방향으로 회동할 때는 힌지축이 되어 안정되게 회동할 수 있는 것이다.That is, as shown in FIG. 3, the pin stopper 6 inserted into both through-holes 22 of the holder 20 moves along the guide groove 12 when the ball member 10 rotates in the horizontal direction so that there is no shaking. When rotating in the vertical direction, it becomes the hinge axis and can rotate stably.
한편, 서포트부재(5)에 의해 이탈이 방지된 볼부재(10)는 상,하 좌,우 회동을 함에 있어서 마찰력의 크기를 상기 서포트부재(5)로써 조절할 수 있다.On the other hand, the ball member 10 is prevented from being separated by the support member (5) can be adjusted by the support member (5) the amount of friction force in the up, down, left, right rotation.
예컨데 회전 마찰력이 커서 뻑뻑할 때는 서포트부재(5)의 나사링(51)을 풀어 밀착력이 약해지도록 하고, 반대로 회전 마찰이 적어서 헐거울 때는 서포트부재(5)의 나사링(51)을 더 깊이 조여 밀착력이 커지게 하면된다.For example, when the rotational friction is large, loosen the screw ring 51 of the support member 5 so that the adhesion is weakened. On the contrary, when the rotational friction is low, loosen the screw ring 51 of the support member 5 deeper. You can increase the adhesion.
그리고 볼부재(6)는 오일리스 프라스틱재로 형성하므로써 윤활유를 사용하지 않아도 된다.The ball member 6 is formed of an oilless plastic material so that it is not necessary to use lubricating oil.
위에서 자세히 설명한 바와 같은 본 발명은 조향장치의 칼럼에 사용되는 유니버셜 조인트를 형성하되, 컵모양의홀더부(20)와 이 홀더부(20)에 끼워진 볼부재(6)로써 관절 모양을 만들고, 그 볼부재(10)에 가이드홈(12)을 형성하되, 홀더부(20)의 양측으로부터 끼운 핀스톱퍼(6)가 가이드홈(12)에 끼워진 채 힌지로 혹은 가이더로 이용되어작동이 원활하게 되는 것이고, 특히 부품수가 적을 뿐만 아니라 중요부품만 정밀가공하기 때문에 제조하기가 쉬우며, 오일리스 플래스틱재를 사용하기 때문에 그리스유를 사용하지 않으면서도 제품이 가벼워 상품성이 크게 향상되는 것이다.The present invention as described in detail above to form a universal joint used in the column of the steering device, to form a joint shape with the cup-shaped holder portion 20 and the ball member 6 fitted to the holder portion 20, Guide grooves 12 are formed in the ball member 10, and the pin stoppers 6 inserted from both sides of the holder part 20 are used as hinges or guiders while being inserted into the guide grooves 12 to facilitate operation. In particular, it is easy to manufacture because only a small number of parts, but also important parts are precisely processed, and because the oilless plastic material is used, the product is light without using grease oil, thereby greatly improving the merchandise.
