본 고안은 자동차의 서스펜션이나 스티어링계통에 사용되는 볼 조인트의 더스트 커버결착구조에 관한 것으로써, 특히 더스트 커버에 요철을 형성하고 에폭시수지계통의 접착제를 사용하여 볼 시트에 결착시킨 것에 관한 것이다.The present invention relates to a dust cover fastening structure of a ball joint used in a suspension or steering system of an automobile, and more particularly, to concavities and convexities formed in a dust cover and to a ball seat using an epoxy resin adhesive.

통상의 볼 조인트는 제1도(a)에서 보는 바와 같이 볼 스터드(1)가 유동삽입된 볼 시트(2)를 하우징(3)에 삽입고정시킨 다음 고무로 된 더스트 커버(4)가 볼 시트(2)의 결합홈에 고정되는 구조로 이루어져 있는 것이다.A conventional ball joint is fixed by inserting a ball seat 2 into which a ball stud 1 is flow-inserted into a housing 3, as shown in FIG. 1 (a), and then a rubber dust cover 4 by a ball seat. (2) consists of a structure fixed to the coupling groove.

위와 같이 만들어진 볼 조인트는 자동차의 서스펜션이나 스티어링계통에 장착되어 사용되고, 작동중 볼 스터드(1)가 회전이나 진동으로 움직일때 더스트 커버(4) 또한 볼 스터드(1)의 작동에 따라 볼 시트(2)에서 이탈되지 않고 작동되어야 되는 것이다.The ball joint made as above is mounted on the suspension or steering system of the vehicle, and when the ball stud 1 moves by rotation or vibration during operation, the dust cover 4 and the ball seat 2 according to the operation of the ball stud 1 It should work without getting out of).

일반적으로 종래 널리 쓰이던 볼 조인트의 더스트 커버 결착구조를 제1도(a),(b)와 함께 살펴보기로 한다.Generally, the dust cover binding structure of the ball joint, which is widely used in the related art, will be described with reference to FIGS. 1A and 1B.

제1도(c)에서 보는 바와 같은 볼 조인트는 금속재인 하우징(3)의 상단에 결합홈(5)을 만들고, 결합홈(5)에서 더스트 커버(4)를 공구를 사용하여 억지삽입한 다음 공구를 사용하여 원형립(6)으로 고정하는 것인 바, 이와같이 더스트 커버(4)를 하우징(3)의 결합홈(5)에 원형립(6)으로 삽입고정할때 수작업으로 인하여 인건비가 많이 소요될 뿐만아니라 대량생산의 걸림돌이 되었던 것이다.As shown in FIG. 1 (c), the ball joint makes a coupling groove 5 in the upper part of the housing 3 made of metal, and inserts the dust cover 4 into the coupling groove 5 by using a tool. When using the tool to fix the circular lip (6) bar, when the dust cover (4) is inserted into the circular lip (6) in the coupling groove 5 of the housing 3, the labor cost is high due to manual labor Not only was it necessary, it was also an obstacle to mass production.

또한 제1도(b)에서 보는 바와 같은 볼 조인트는 보강편(7)을 더스트 커버(4)를 성형할 때 더스트 커버(4)와 일체로 사출성형하여, 하우징(3)의 결합홈(5)에 끼워 고정하는 것인 바 이와 같이 고정되는 더스트 커버(4)를 볼 시트(2)의 결합홈(5)에 삽입하는 공정은 간단하게 이루어지지만 보강편(7)을 준비하는 과정에 많은 문제점이 있었던 것이다.In addition, the ball joint as shown in FIG. 1 (b) is injection molded integrally with the dust cover 4 when forming the dust cover 4, so that the coupling groove 5 of the housing 3 is formed. Inserting the dust cover 4 fixed in this way into the coupling groove 5 of the ball seat 2 is simple, but there are many problems in the process of preparing the reinforcing piece 7. This was there.

즉 보강편(7)을 일정형상으로 프레스 성형한 다음 열처리하여 보강편(7)에 탄력성을 부여해야 하고, 탄력성을 가진 보강편(7)을 더스트 커버(4)에 정확히 삽입하여 일체로 사출성형해야 하는 어려움 뿐만아니라 볼 시트(2)의 결합홈(5) 가공치수가 각 제품간에 편차없이 정확하게 가공해야 하는 문제점이 있었던 것이다.That is, the reinforcing piece 7 is press-molded to a predetermined shape and then heat treated to give elasticity to the reinforcing piece 7, and the reinforcing piece 7 having elasticity is accurately inserted into the dust cover 4 to integrally injection molding. In addition to the difficulty to be done, there was a problem in that the machining groove 5 of the ball seat 2 should be accurately processed without deviation between the products.

이에 본 고안인은 종래 더스트 커버를 하우징에 고정하는데 따랐던 문제점을 일소한 본 고안을 고안하게 되었는 바 부수되는 도면가 함께 본 고안을 살펴보기로 한다.In this regard, the present inventors will devise the present invention to solve the problems caused by fixing the dust cover to the housing, and thus the present invention will be described together with the accompanying drawings.

제2도에서 보는 바와 같이 더스트 커버(4)하단에 두꺼운 고정부(8)를 만들되, 고정부(8)의 외측에는 돌출된 누름턱(9)을 만들고 내측에는 오목, 볼록한 요철(10)을 형성한 것이며, 하우징(3)의 결합홈(5)상부에 경사면(11)을 형성한 것이다.As shown in FIG. 2, a thick fixing part 8 is formed at the bottom of the dust cover 4, but a protruding pressing jaw 9 is formed on the outside of the fixing part 8, and concave and convex unevenness 10 is formed on the inside of the fixing part 8. The inclined surface 11 is formed in the upper part of the coupling groove 5 of the housing 3.

위에서 고정부(8)내측에 형성되는 요철의 수는 필요에 따라 달리할 수 있겠으나 요철(10)의 끝단부는 항상 끼움경사면(12)이 형성되어야 하는 것이다.The number of concavities and convexities formed on the inside of the fixing part 8 may vary depending on necessity, but the end of the concavities and convexities 10 should always have a fitting inclined surface 12.

즉 요철(10)의 끝단부가 더스트 커버(4)내측에서 외측으로 경사지도록 끼움경사면(12)이 형성되야만 더스트 커버(4)가 공구(13)에 의해 조립될 때 하우징(3)의 상단에 형성된 경사면(11)을 따라 쉽게 조립될 수 있는 것이다.That is, the fitting inclined surface 12 must be formed so that the end portion of the unevenness 10 is inclined from the inside of the dust cover 4 to the outside of the housing 3 when the dust cover 4 is assembled by the tool 13. It can be easily assembled along the formed inclined surface (11).

위와 같은 본 고안의 조립과정을 살펴 보면 끝단의 고정부(8)내측에 요철(10)과 외측에 누름턱(9)이 형성된 고무재질의 더스트 커버(4)를 사출성형하고, 결합홈(5)에 에폭시수지계통의 접착제(14)가 발려진 하우징(3)에 공구(13)를 사용하여 더스트 커버(4)의 누름턱(9)을 더스트 커버(4)의 끼움경사면(12)이 하우징(3)의 경사면(11)을 따라 안내되어 결합홈(5)에 안착하게 되는 것이다.Looking at the assembly process of the present invention as described above injection molding the dust cover 4 of the rubber material formed with the concavo-convex 10 and the pressing jaw 9 on the inside of the fixing portion 8 of the end, the coupling groove 5 The pressing jaw (9) of the dust cover (4) to the housing (3) on which the epoxy resin-based adhesive (14) was applied to the housing (3). Guided along the inclined surface 11 of (3) is to be seated in the coupling groove (5).

위와 같이 결합홈(5)에 더스트 커버(4)의 고정부(8)가 안착되면 결합홈(5)에 발려져 있는 접착제(14)에 의해 더스트 커버(4)가 고정되는 것이며, 이때 접착제(14)로 접착되는 고정부(8)의 요철(10)은 오목,볼록부로 이루어져 있는 접착면이 최대가 되는 것이고, 특히 요철(10)의 오목부는 많은 량의 접착제가 결합홈(5)에 발려진 경우에 대비한 접착제(14)수납공간 역할을 수행하게 되는 것이다.As described above, when the fixing part 8 of the dust cover 4 is seated in the coupling groove 5, the dust cover 4 is fixed by the adhesive 14 coated on the coupling groove 5, wherein the adhesive ( 14) The concave and convex portion 10 of the fixing portion 8 to be bonded is the concave, convex portion of the adhesive surface is the maximum, in particular, the concave portion of the concave and convex portion 10 is a large amount of adhesive is applied to the coupling groove (5) It will serve as a storage space for the adhesive 14 in case of loss.

위에서 금속재인 볼 시트(2)가 고무재인 더스트 커버(4)를 부착하는데 사용되는 접착제는 에폭시수지계통의 접착제가 접착력에 있어서 유리하고, 특히 비스페놀 A(bisphenol-A)계인 디 글리시딜 에테르(di glycidy lether)가 유리하며, 경화제는 엠 페닐렌 디아민(m-phenylene diamine) 5 ~ 10% (중량비)를 사용하는 것이 가장 우수한 접착력을 발휘하게 되는 것이다.The adhesive used for attaching the dust cover 4 of the metal ball sheet 2 to the rubber is advantageous in that the adhesive of the epoxy resin system is advantageous in adhesion, and in particular, a diglycidyl ether of bisphenol A (bisphenol-A) ( Di glycidy lether is advantageous, and the curing agent is 5 to 10% by weight (m-phenylene diamine) will be the best adhesion.

위에서 살펴 본 바와 같이 본 고안은 더스트커버의 단부에 두꺼운 고정부를 만들고 고정부에 누름턱과 요철을 형성하여 공구를 사용하여 누름턱을 눌러 접착제가 발려진 하우징의 끼움홈에 더스트커버를 삽입하여 접착고정함으로써, 종래의 문제점이던 제작공정의 복잡함이나 수작업으로 인하여 생산성이 저하되던 문제점을 일소한 유용한 고안인 것이다.As described above, the present invention forms a thick fixing part at the end of the dust cover, and forms the pressing jaw and the uneven portion at the fixing part by pressing the pressing jaw by using a tool to insert the dust cover into the fitting groove of the adhesive coated housing. By fixing the adhesive, it is a useful design to eliminate the problem that the productivity is lowered due to the complexity of the manufacturing process or manual work that was a conventional problem.
