Description
본 고안은 자동차 조향장치의 랙바와 이너 볼 조인트 연결구조에 관한 것으로, 상세하게는 랙바의 양단과 이너 볼 조인트를 연결함에 있어 연결상태가 견고하며 조립구조 및 과정이 간단하도록 탈.부착구조를 형성하여 개재시킨 자동차 조향장치의 랙바와 이너 볼 조인트 연결구조에 관한 것이다.The present invention relates to the connection structure of the rack bar and the inner ball joint of the steering device of the vehicle, and in detail, in connecting the both ends of the rack bar and the inner ball joint, the connection state is solid and the detachable structure is formed to simplify the assembly structure and the process. The present invention relates to a rack bar and an inner ball joint connection structure of a vehicle steering device interposed therebetween.
일반적으로, 자동차의 조향장치는 조향 휠과, 이에 연결되는 조향샤프트, 이 샤프트를 외부에서 커버하면서 지지하는 칼럼 튜브와, 상기 조향 샤프트에 연결되어 비틀림 회전력을 전달하는 유니버셜 조인트와, 이 유니버셜 조인트에 의하여 전달되는 회전력을 전달하여 주는 피니언 기어축과, 상기 피니언 기어축에 연결되어 좌,우측 조향력을 전달 받는 랙바로 이루어져 랙바와 연결된 타이로드등의 연결수단을 통해 바퀴를 움직여 자동차를 조향하게 된다.In general, a steering device of an automobile includes a steering wheel, a steering shaft connected thereto, a column tube supporting and supporting the shaft from the outside, a universal joint connected to the steering shaft to transmit a torsional rotational force, and the universal joint. Pinion gear shaft for transmitting the rotational force transmitted by the, and the rack bar is connected to the pinion gear shaft is transmitted to the left and right steering force to move the wheel through the connecting means, such as tie rods connected to the rack bar to steer the car.
여기에서 랙바는 수평상태에서 좌,우측으로 좌우 이동되는 이동수단으로써 일부구간은 유압 실린더의 내부에서 유압에 따라 이동되도록 실린더 내측에서 피스톤 부재와 함께 관설되어 있고 일부분은 피니언 기어와 맞물리는 랙기어를 형성하여 피니언 기어로부터 전달되는 회전력이 수평 이동력으로 바뀌게 되며 양단은 바퀴와 연결되도록 이너 볼 조인트를 형성하게 된다.Here, the rack bar is a means of moving left and right in the horizontal state, and some sections are installed together with the piston member inside the cylinder to move according to the hydraulic pressure inside the hydraulic cylinder, and a part of the rack gear is engaged with the pinion gear. The rotational force transmitted from the pinion gear is converted into a horizontal movement force, and both ends form an inner ball joint to be connected to the wheel.
여기에서 랙바(100)와 이너 볼 조인트(200)를 연결함에 있어서 종래에는 랙바(100)의 단부측 내부면에 일정길이 나선(102)을 형성하고 이너 볼 조인트(200)는 자체의 일측면을 절삭 가공하여 상기 나선(102)에 대응하는 나선(202)을 형성한 돌출봉(204)을 형성하며 이와같은 나선(102)(202)의 대응 맞춤후 풀림을 방지하기 위하여 별도의 탭 와셔(300)를 랙바(100)와 이너 볼 조인트(200)가 나사맞춤으로 연결하는 사이에 개재시킨 뒤 이너 볼 조인트(200)에 탭 와셔(300)을 코킹(caulking) 처리하여서 되는 것이다.Here, in connecting the rack bar 100 and the inner ball joint 200, conventionally, a spiral thread 102 is formed on the inner surface of the end side of the rack bar 100, and the inner ball joint 200 has one side thereof. Cutting to form a protruding rod 204 to form a spiral 202 corresponding to the spiral 102, and separate tab washer 300 to prevent loosening after the corresponding alignment of the spiral 102 (202) ) Is interposed between the rack bar 100 and the inner ball joint 200 by screwing, and then caulking the tap washer 300 to the inner ball joint 200.
그러나, 이와같은 랙바와 이너 볼 조인트의 연결구조는 구조의 부품 자체가 복잡하고 이 부품들을 처리하기 위한 조립공정이 많이 소요되고,탭와셔를 동원한 코킹 작업 및 이너 볼 조인트 몸체를 일일이 별도의 가공 작업을 통하여 나선과 이 나선이 형성된 돌출부를 가공해야 되는 번거로움등이 있었다.However, such a connection structure of the rack bar and the inner ball joint is complicated in the parts of the structure itself, takes a lot of assembly process to process these parts, caulking work using a tap washer and separate processing work of the inner ball joint body individually There was a hassle to process the helix and the protrusion on which the helix was formed.
따라서, 랙바와 이너 볼 조인트의 연결시 유지되어야 할 내구성 및 체결력등이 유지되면서 상기와 같은 이너 볼 조인트 가공에 따른 가공 공정상의 문제점을 개선하고 탈부착이 용이한 랙바와 이너 볼 조인트의 연결구조가 필요로 하게 되었다.Therefore, while maintaining the durability and fastening force to be maintained when connecting the rack bar and the inner ball joint, it is necessary to improve the problems in the machining process according to the inner ball joint processing as described above, and the connection structure of the rack bar and the inner ball joint that is easily removable. Was done.
본 고안은 상기 종래의 제반문제점을 해결하고자 안출된 것으로, 랙바와 이너 볼 조인트를 연결함에 있어 나사맞춤 연결부가 갖는 나선부분의 이완을 방지하기 위한 탭 와셔와 같은 부품을 사용하지 않고 연결 강도를 유지하고 오히려 조립 생산 공정이 수월하도록 탈부착이 가능한 랙바와 이너 볼 조인트 연결구조를 제공하고자 하는 데에 그 목적이 있다.The present invention has been made to solve the above-mentioned conventional problems, maintaining the connection strength without using parts such as tap washers to prevent the loosening of the spiral portion having a screw fitting connection in connecting the rack bar and the inner ball joint Rather, the purpose is to provide a removable rack bar and inner ball joint connection structure to facilitate the assembly production process.

이하, 본 고안의 바람직한 실시예를 첨부 도면과 함께 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
첨부도면중 도 3은 본 고안에 따른 랙바와 이너 볼 조인트의 연결상태 보인 요부 분해사시도, 도 4는 본 고안에 따른 랙바와 이너 볼 조인트의 연결상태를 보인 결합단면도로써, 랙바(29)와 이너 볼 조인트(21)의 연결구조에 있어서, 중공의 양끝단 내주면에 암나사(28)가 형성되고 그 외주면에 관통된 요홈(30)을 형성한 랙바(29)와; 상기 랙바(29)의 내주면에 체결하도록 그 외주면에 수나사(24)가 형성된 중공의 돌출봉(23)을 형성하며, 상기 돌출봉(23)의 끝단 외주면에서 돌출되어 랙바(29)의 요홈(30)에 고정하기 위한 돌기부(25)를 형성하고, 상기 돌출봉(23)의 내.외측에 관통된 절개홈(27)을 형성한 이너 볼 조인트(21)와; 상기 돌출봉(23)의 외주면에 결합되는 체결너트(33)를; 포함하여 구성된다.Figure 3 is an exploded perspective view of the main part showing the connection state of the rack bar and the inner ball joint according to the present invention, Figure 4 is a combined cross-sectional view showing the connection state of the rack bar and the inner ball joint according to the present invention, the rack bar 29 and the inner In the connection structure of the ball joint (21), the female thread 28 is formed on the inner circumferential surface of both ends of the hollow and the rack bar 29 formed with the groove 30 penetrated through the outer circumferential surface; A hollow protrusion bar 23 having a male screw 24 is formed on the outer circumferential surface thereof so as to be fastened to the inner circumferential surface of the rack bar 29, and protrudes from the outer circumferential surface of the end of the protrusion bar 23 to form the recess 30 of the rack bar 29. An inner ball joint 21 formed with a protrusion 25 for fixing to the inner side, and forming a cutout groove 27 penetrating inside and outside of the protruding bar 23; A fastening nut 33 coupled to an outer circumferential surface of the protruding bar 23; It is configured to include.
그리고, 상기와 같은 랙바(29)와 이너 볼 조인트(21)의 조립은 이너 볼 조인트(21)의 돌출봉(23)부위의 양끝단에 형성된 돌기부(25)를 랙바(29)의 외주면에 형성된 요홈(30)으로 결합 고정시 상기 돌출봉(23)의 외측을 눌러주면서 랙바(29)의 내주면으로 삽입하면서 돌기부(25)가 요홈(30)의 위치에 왔을 때 결합되어 고정되는 것이며, 상기 돌출봉(23)의 외측으로 체결된 체결너트(33)를 적당히 랙바(29)쪽으로 조절하여 랙바(29)와 이너 볼 조인트(21)를 견고하게 고정하는 것이다.And, the assembly of the rack bar 29 and the inner ball joint 21 as described above is formed on the outer circumferential surface of the rack bar 29 of the protrusions 25 formed on both ends of the protruding bar 23 of the inner ball joint 21 When the coupling is fixed to the groove 30, while pressing the outside of the protruding bar 23 is inserted into the inner circumferential surface of the rack bar 29, the projection 25 is coupled and fixed when it comes to the position of the groove 30, the protrusion By adjusting the fastening nut 33 fastened to the outside of the rod 23 toward the rack bar 29, the rack bar 29 and the inner ball joint 21 are firmly fixed.
상기 랙바(29)와 이너 볼 조인트(21)의 탈거시는 상기 체결의 역순이며 상기 돌출봉(23)에 형성된 절개홈(27)의 형상으로 랙바의 내주면에 삽입을 용이하게 하기 위한 것이다.When the rack bar 29 and the inner ball joint 21 are removed, the reverse order of the fastening and the shape of the cutting groove 27 formed in the protruding bar 23 are to facilitate insertion into the inner circumferential surface of the rack bar.
본 고안은 체결너트를 이용하므로서 기존의 탭와셔를 사용한 코킹공정을 없앨수 있을 뿐만 아니라 조립이 수월해지고 단가를 절약하게 되는 것이다.The present invention not only eliminates the caulking process using a conventional tap washer by using a fastening nut, but also facilitates assembly and saves cost.
이와같이 본 고안은 종래 탭와셔를 이용하여 랙바와 이너 볼 조인트사이를 연결하는 구조에 있어 나타나는 문제점을 개선하게 되는 바,예를들면 나사맞추된 랙바와 이너 볼 조인트 부재와의 이완을 방지하기 위한 탭 와셔와 같은 부속수단이 필요하게 되어 부품수 공정수를 높이는 결과를 초래하였고, 코킹을 위한 이너 볼 조인트 부재의 몸체를 절삭 및 상당하게 가공해야되는 가공 공정상의 번거로움등이 있었으나, 조립공정을 단순화하여 조립시간의 단축 및 탈부착이 용이하여 조립의 편의성이 용이하게 하는 매우 유용한 고안인 것이다.As such, the present invention improves the problems in the structure connecting the rack bar and the inner ball joint by using a conventional tap washer, for example, a tab for preventing the loosening of the threaded rack bar and the inner ball joint member. The additional means such as washers are required to increase the number of parts, and the process of cumbersome processing of the inner ball joint member for caulking and processing is required, but the assembly process is simplified. By shortening the assembly time and easy to detach it is a very useful design to facilitate the ease of assembly.
