본 고안은 자동차의 서스펜션이나 스티어링계통에 사용되는 볼 조인트에 관한 것으로서, 특히 볼 조인트를 조립할 때 각 부품의 크기오차로 인한 조립오차를 극복할 수 있는 볼 조인트에 관한 것이다.The present invention relates to a ball joint used in the suspension or steering system of the vehicle, and more particularly to a ball joint that can overcome the assembly error due to the size error of each part when assembling the ball joint.

자동차에서 볼 조인트는 스티어링이나 서스펜션계통에 사용되며, 정확하고 견고하게 조립되어야 안전사고를 방지할 수 있는 중요한 부품인 것이다.In automobiles, ball joints are used in steering and suspension systems, and they are important parts to prevent safety accidents when assembled correctly and firmly.

통상의 자동차용 볼 조인트를 만들 때 사용되는 부품은 제1도에 보는 바와 같이 하단에 원형의 구두부(2)를 가진 볼 스터드(1)와 중앙에 삽입공(4)이 형성된 볼 시트(3), 하우징(5) 및 플러그(6)로 구성되어 있다.The parts used in making a conventional automotive ball joint are a ball seat 3 having a ball stud 1 having a circular shoe part 2 at the bottom and an insertion hole 4 in the center, as shown in FIG. ), A housing 5 and a plug 6.

위와 같이 구성된 볼 조인트를 조립하는 공정을 살펴보면, 볼 스터드(1)의 구두부(2)를 볼 시트(3)의 삽입공(4)에 억지 삽입하고, 볼 시트(3)를 하우징(5)에 끼운 다음 플러그(6)를 사용하여 고정하는 것이다.Looking at the process of assembling the ball joint configured as described above, forcibly inserting the shoe portion (2) of the ball stud (1) into the insertion hole (4) of the ball seat (3), the ball seat (3) the housing (5) And then use the plug (6) to fix it.

위와 같이 조립된 자동차용 볼 조인트의 볼 시트(3)는 하우징(5)에 완전히 끼움 고정되어 회전되거나 움직이지 않아야 되고, 볼 스터드(1)의 구두부(2)는 볼 시트(3)의 삽입공(4) 속에서 원활하게 움직이되 볼 스터드(1)가 수직으로 움직이는 힘에 의해 일탈되지 않아야 되는 것이다.The ball seat 3 of the automotive ball joint assembled as described above is completely fitted into the housing 5 and should not be rotated or moved, and the shoe part 2 of the ball stud 1 is inserted into the ball seat 3. The ball (4) moves smoothly, but the ball stud (1) should not be deviated by the vertical moving force.

위와 같이 조립되기 위해서는 볼 시트의 삽입공내주연(7)과 볼 스터드(1)의 구두부외주연(8) 및 볼 시트(3)의 볼 시트외주연(9), 하우징(5)의 하우징내주면(10)이 정확한 치수로 만들어져 조립되어야 볼 조인트가 원활한 작동을 하게 되는 것이다.In order to be assembled as described above, the inner circumferential edge of the ball seat (7) and the outer circumference (8) of the shoe stud (1) and the outer circumference (9) of the ball seat (3), the housing inner peripheral surface of the housing ( 10) It must be made and assembled with the correct dimensions for the ball joint to work smoothly.

즉 볼 스터드(1)의 구두부외주연(8)과 볼 시트(3)의 삽입공내주연(7) 사이에 생기는 공차가 클 때는 볼 스터드(1)가 볼 시트(3) 속에서 원활하게 움직이지만 볼 스터드(1)가 볼 시트(3) 속에 헐겁게 끼움되어 정상토크가 발생되지 않고, 공차가 작을 때는 볼 스터드(1)의 구두부(2)가 볼 시트(3)에 국부적으로 접촉하면서 작동되어 토크가 높아지거나 불균일한 토크가 발생될 뿐만 아니라 볼 스터드(1)가 볼 시트(3) 속에서 원활하게 움직이지 못하는 문제점이 발생되는 것이며, 또한 하우징(5)의 하우징내주면(10)과 볼 시트(3)의 볼 시트외주연(9) 사이에 공차가 크면 볼 시트(3)가 하우징(5) 내에서 공회전하게 되고 공차가 없으면 조립이 불가능해지는 문제가 발생되는 것이다.That is, when the tolerance between the outer circumferential edge 8 of the ball stud 1 and the inner circumferential edge 7 of the ball seat 3 is large, the ball stud 1 moves smoothly in the ball seat 3 When the ball stud 1 is loosely inserted into the ball seat 3 and no normal torque is generated, when the tolerance is small, the shoe part 2 of the ball stud 1 is operated while locally contacting the ball seat 3 Not only does the torque increase or the non-uniform torque is generated, but the ball stud 1 does not move smoothly in the ball seat 3, and the housing inner peripheral surface 10 and the ball seat of the housing 5 also occur. If the tolerance between the ball seat outer periphery 9 of (3) is large, the ball seat 3 will be idle in the housing (5), there is a problem that the assembly is impossible without the tolerance.

이에 본 고안인은 볼 시트와 볼 스터드의 구두부를 제3도(a)에서 보는 바와 같이 수지몰드로 일체로 성형하되, 볼 시트의 볼 시트외주면에 브이홈과 돌출턱을 형성한 본 고안을 고안하게 되었는 바, 부수되는 도면과 함께 본 고안을 상세히 살펴보기로 한다.The inventors of the present invention devised the present invention in which the shoe parts of the ball seat and the ball stud are integrally molded with the resin mold as shown in FIG. 3 (a), but the V groove and the protruding jaw are formed on the outer circumferential surface of the ball seat. The present invention together with the accompanying drawings will be described in detail.

본 고안은 제3도에서 보는 바와 같이, 볼 스터드(1)의 구두부(2)와 볼 시트(3)를 수지몰드공법을 사용하여 일체로 성형하되, 볼 시트(3)의 볼 시트외주면에 브이홈(12)을 경계로 다수개의 돌출턱(11)을 연속 형성한 것이다.The present invention, as shown in Figure 3, the shoe part 2 and the ball seat 3 of the ball stud (1) is integrally molded by using a resin molding method, but the ball seat outer peripheral surface of the ball seat (3) The plurality of protruding jaws 11 are continuously formed at the boundary of the V-groove 12.

여기서 상기 수지몰드공법은 사출성형의 일종인 인서트 사출성형으로서, 상기 볼 시트(3)를 성형하는 사출 금형내에 인서트물 즉 상기 볼 스터드(1)의 구두부(2)를 넣고 소정의 온도에서 유동적으로 가변한 합성수지를 상기 금형 내부에 주입한 뒤에 냉각하여 볼 스터드(1)의 구두부(2)가 삽입된 볼 시트(3)를 만들게 되는 것이다.Herein, the resin molding method is insert injection molding, which is a kind of injection molding, in which an insert, that is, an oral part 2 of the ball stud 1, is placed in an injection mold for molding the ball sheet 3 and flows at a predetermined temperature. The synthetic resin is injected into the mold and then cooled to make the ball seat 3 into which the shoe portion 2 of the ball stud 1 is inserted.

물론 상기 볼 스터드(1)의 구두부(2)는 금속재질이며, 볼 시트(3)는 합성수지재이기 때문에, 구두부(2)와 볼 시트(3)를 완전히 접착하지 않게 된다.Of course, since the shoe part 2 of the ball stud 1 is made of metal, and the ball seat 3 is made of synthetic resin, the shoe part 2 and the ball seat 3 are not completely bonded.

위와 같이 볼 시트(3)의 볼 시트외주면에 형성된 돌출턱(11)은 볼 시트(3)에 끼움되는 하우징(5)의 하우징내주면(10) 크기보다 돌출턱(11)이 크게 만들어진 것으로서, 바람직하기로는 하우징내주면(10)의 지름보다 0.02mm ∼ 1.15mm 정도 크게 만드는 것이 좋다.The protruding jaw 11 formed on the ball seat outer circumferential surface of the ball seat 3 as described above is preferably made of the protruding jaw 11 larger than the size of the housing inner circumferential surface 10 of the housing 5 fitted to the ball seat 3. In the following description, it is preferable to make the housing inner circumferential surface 10 larger than 0.02 mm to 1.15 mm.

즉, 제3도 (b)에서 보는 바와 같이 하우징내주면(10)의 지름을 'A'로 하고 돌출턱(11)의 지름을 'B'로 한다면, 'B'를 'A'보다 0.02mm ∼ 0.05mm 크게 만드는 것이 바람직하다는 것이다.That is, as shown in FIG. 3 (b), if the diameter of the housing inner circumferential surface 10 is 'A' and the diameter of the protruding jaw 11 is 'B', 'B' is 0.02 mm to 'A'. It is desirable to make 0.05mm larger.

또한 브이홈(12)을 경계로 돌출턱(11)은 연속 형성되는 것이며, 필요에 따라 그 수를 조절할 수 있음은 당연한 것이고, 돌출턱(11)의 양측은 경사면(14)을 형성하여 조립을 쉽게 만드는 것이다.In addition, the protruding jaw 11 is continuously formed at the boundary of the v-groove 12, and it is natural that the number can be adjusted as needed. Both sides of the protruding jaw 11 form an inclined surface 14 to assemble the assembly. It's easy to make.

위에서 살펴본 바와 같은 본 고안은 볼 스터드(1)의 구두부(2)와 볼 시트(3)를 수지몰드공법을 사용하여 일체로 제작함으로써, 각 부품이 허용오차에서 조금 벗어나더라도 항상 균일한 접촉을 하면서 볼 스터드(1)가 볼 시트(3)속에서 작동할 수 있게 된 것이고, 볼 시트(3)가 하우징(5)에 끼움될 때 돌출턱(11)이 찌그러지면서 밀착 고정됨으로써, 작동중 볼 시트(3)가 하우징(5)속에서 회전하거나 움직이는 것을 근본적으로 방지할 수 있게 된 것이다.The present invention as described above, by manufacturing the shoe part (2) and the ball seat (3) of the ball stud (1) integrally using the resin molding method, so that even if each part is slightly out of tolerance, always uniform contact While the ball stud 1 is able to operate in the ball seat 3, the projection jaw 11 is crushed and tightly fixed when the ball seat 3 is fitted to the housing 5, It is possible to fundamentally prevent the seat 3 from rotating or moving in the housing 5.

또한 본 고안 볼 시트의 돌출턱(11) 양측에 형성된 경사면(14)은 하우징(5)에 볼 시트(3)가 쉽게 끼움되도록 도와주는 역할을 수행하고, 브이홈(12)은 돌출턱(11)이 쉽게 찌그러들 수 있도록 도와주는 역할을 수행하여 하우징내주면(10)과 볼시트외주면(9) 사이에 생기는 제조 오차에 따른 조립 오차를 극볼할 수 있게 한 것이다.In addition, the inclined surface 14 formed on both sides of the protruding jaw 11 of the subject innovation ball seat serves to help the ball sheet 3 is easily fitted to the housing 5, the v-groove 12 is a protruding jaw 11 ) Serves to help crush easily, so that the assembly errors due to manufacturing errors occurring between the housing inner circumferential surface 10 and the ball seat outer circumferential surface 9 can be maximized.

위에서 살펴본 바와 같이 본 고안은 종래 볼 조인트가 가지고 있던 부품의 제조오차로 인한 문제점을 해결함으로써, 불량을 최소화하고 나아가 제품의 신뢰도를 높일 수 있는 유용한 고안인 것이다.As described above, the present invention solves the problems caused by the manufacturing error of the parts of the conventional ball joint, thereby minimizing defects and further increasing the reliability of the product.
