Description

자동차용 컬럼샤프트의 로킹링 결합구조Locking ring coupling structure of automotive column shaft

본 발명은, 자동차용 컬럼샤프트의 로킹링에 관한 것으로서, 특히, 원형상으로된 컬럼샤프트의 양측에 평면부를 형성하고 이 평면부에는, 양측에 평면부를 가지고 있고, 외면 상측에는 로킹공을 형성하고 있으며, 내부의 양측평면에는 너얼링부를 형성하고 있는 로킹링을 결합한뒤, 로킹링의 양측 평면부를 코킹하여 컬럼샤프트에 고정시킬수 있도록된 자동차용 컬럼샤프트의 로킹링 결합구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking ring of a column shaft for automobiles. In particular, the planar portions are formed on both sides of the circular column shaft, and the planar portions have flat portions on both sides, and the locking holes are formed on the outer surface. In addition, the both sides of the inner surface is coupled to the locking ring forming the knurling portion, and then to the locking ring coupling structure of the automotive column shaft to be fixed to the column shaft by caulking both flat portions of the locking ring.

종래의 자동차용 컬럼샤프트의 로킹장치는 제4도에 나타내었다. 즉, 상기의 로킹장치는 차량의 도난을 방지하기 위하여 장착되는 장치로서, 튜브(27)에 결합되어있는 로크기구(29)에 키를 꼽아서 잠그면 로크기구(29)의 로킹편(30)이 튀어나오면서 컬럼샤프트(21)의 로킹링(23)에 형성된 로킹홈(24)으로 삽입되어지게 된다. 따라서, 컬럼샤프트(21)의 회전이 불가능하게 되고, 아울러 컬럼샤프트(21)와 연결되어있는 핸들의 회전도 불가능하게 되기 때문에 차량의 도난을 방지 할 수 있게 되는 것이다. 그리고, 원형상의 컬럼샤프트(21)에 원형상의 로킹링(23)을 결합하는 수단으로는, 외주면 일측부에 로킹공(4)을 형성하고있는 로킹링(23)을 원형상의 컬럼샤프트(21)에 끼운뒤 로킹링(23)의 양측 주연부를 용접(25)하는 수단으로 로킹링(23)을 결합하였었다.A conventional locking device for a car column shaft is shown in FIG. That is, the locking device is a device mounted to prevent theft of the vehicle. When the key is locked to the locking mechanism 29 coupled to the tube 27, the locking piece 30 of the locking mechanism 29 pops up. It will be inserted into the locking groove 24 formed in the locking ring 23 of the column shaft 21. Therefore, since the rotation of the column shaft 21 is impossible, and also the rotation of the handle connected to the column shaft 21 is impossible, it is possible to prevent theft of the vehicle. As a means for coupling the circular locking ring 23 to the circular column shaft 21, the locking ring 23 having the locking hole 4 formed on one side of the outer circumferential surface thereof has a circular column shaft 21. Locking ring 23 was engaged by means of welding 25 to both sides of the locking ring 23 after being inserted in the.

상기와 같은, 종래의 로킹링을 결합하는 수단은, 상당한 문제점을 안고 있다. 즉, 컬럼샤프트의 축방향의 위치와, 로킹공이 로크기구와 정확하게 일직선상으로 위치되어 로크기구의 로킹편과 상호 작용에 의해 로킹작용을 할수 있는 것인바, 종래의 구조에서는 상기의 축방향위치와 로킹공의 각도를 일치시키는 작업이 매우 어렵게 되어 있다. 따라서, 이를 맞추기 위해 상당한 사건을 낭비하고 있는 실정이며 불량률이 높게 나타나는 문제점을 가지고 있었다. 그리고, 정확한 위치와 각도를 맞춘 상태에서 로킹링을 고정시키는 수단을 용접에 의해 해결하고 있기 때문에 용접시의 움직이나 흔들림 등에 의해 애써 맞추어 놓은 위치와 각도가 흐트려지게 되어 재차 맞추어야하는 등의 번거롭고 불편한 문제점등을 가지고 있었다.As mentioned above, the means for engaging the conventional locking ring suffers from considerable problems. That is, the position of the column shaft in the axial direction and the locking hole are positioned exactly in line with the locking mechanism so that the locking action can be performed by interaction with the locking piece of the locking mechanism. Matching the angle of the locking hole becomes very difficult. Therefore, in order to meet this situation, a considerable amount of wasted was a problem that the defect rate is high. In addition, since the means for fixing the locking ring is fixed by welding in a state where the correct position and angle are set, the position and angle set by the movement or shaking at the time of welding are blurred. I had a problem.

이러한 종래의 문제점등을 해결보완 하기위하여 본 발명은, 튜브의 삽입공에 로킹편을 결합하고있는 로크기구를 결합시키고, 튜브의 내부에는 로킹링을 결합하고있는 컬럼샤프트를 베이링과 함께 결합시키고 있는 구성에 있어서, 상기 컬럼샤프트의 양측에 평면부를 형성하고 평면부가 끝난지점에는 걸림부를 형성한 다음, 상기의 컬럼샤프트의 끝단부로, 양측에 평면부를 형성하고 있고, 외주면 상측에는 로킹공을 형성하고 있으며 내부의 평면에는 너얼링을 형성하고 있는 로킹링을 결합시키되, 로킹링이 컬럼샤프트의 걸림부에 위치되도록 끼워서 결합시키며, 상기 로킹링의 양쪽 평면부를 코킹작업하여 이 코킹부에 의해 로킹링을 컬럼샤프트에 고정시킬수 있도록 하면 본 발명의 목적을 달성 할수 있게 된다.In order to solve such a conventional problem, the present invention, the locking mechanism is coupled to the locking piece coupled to the insertion hole of the tube, and the column shaft coupling the locking ring to the inside of the tube coupled with the bearing In the configuration, a flat portion is formed on both sides of the column shaft, and a locking portion is formed at the end of the flat shaft portion, and a flat portion is formed on both sides of the column shaft end, and a locking hole is formed on the outer circumferential surface. The inner ring is combined with a locking ring forming a knurling ring, and the locking ring is fitted so that the locking ring is positioned at the engaging portion of the column shaft. The locking ring is fixed by the caulking part by caulking both flat portions of the locking ring. By allowing to be fixed to the column shaft it is possible to achieve the object of the present invention.

Both sides of the locking ring 3 are also machined to form the planar portion 3 ', and a locking hole 4 is formed in the upper portion so that the locking piece 10 can be easily inserted.

또한 로킹링(3)의 내부에 형성된 평면부에는 너얼링부(5)를 형성하여 컬럼샤프트(1)의 평면부(2)로 끼워질 때의 원할함을 얻을수 있도록 배려하고 있다. 상기와 같이 된 로킹링(3)을 컬럼샤프트(1)의 평면부에 형성된 걸림부(1')까지 삽입결합한 뒤 로킹링(3)의 양쪽 평면부(3')를 코킹 작업하여 코킹부(11)에 의해 로킹링(3)을 컬럼샤프트(1)에 고정시킬수 있도록 된 구성이다.In addition, the planar portion formed inside the locking ring 3 is formed so as to obtain smoothness when the fitting portion 5 is fitted into the planar portion 2 of the column shaft 1. Inserting the locking ring 3 as described above to the engaging portion 1 'formed on the flat portion of the column shaft 1, and then caulking both flat portions 3' of the locking ring 3 to the caulking portion ( 11) the locking ring 3 can be fixed to the column shaft 1 by means of the above.

이와 같이 된 본 고안의 작용을 설명하기로 한다.The operation of the present invention as described above will be described.

먼저, 컬럼샤프트(1)와 로킹링(3)을 별도로 가공한 뒤, 로킹링(3)을 컬럼샤프트(1)의 평면부(2)로 끼우면 로킹링(3)내부의 평면부에 형성된 너얼링부(5)에의해 적은 마찰을 일으키면서 쉽게 결합되어 진다. 그리고, 상기의 로킹링(3)은 컬럼샤프트(1)의 평면부(2)가 끝나는 지점에 형성된 걸림부(1')까지 밀어넣은 다음 로킹링(3)의 양쪽 평면부(2)를 제3도와 같이 코킹을 하여 코킹부(11)를 형성시키면 로킹링(3)의 고정이 완료되어 진다. 상기와 같이 로킹링(3)을 고정하고 있는 컬럼샤프트(1)를 튜브(7)의 내부로 베어링과(6)함께 결합시키면, 제2도와 같이 튜브(7)의 삽입공(8)위치에 로킹링(3)이 정확하게 위치되는 상태가 된다. 따라서, 로크기구(9)에 키이를 꽂은 뒤 회전을 시키면 로크기구(9)의 로킹편(10)이 로킹링(3)의 로킹공(4)으로 정확하게 삽입되는 것이므로 원할한 로킹작용을 할수 있는 것이다.First, the column shaft 1 and the locking ring 3 are processed separately, and then the locking ring 3 is inserted into the flat portion 2 of the column shaft 1 to form a nual formed in the flat portion inside the locking ring 3. The ring portion 5 is easily engaged with less friction. Then, the locking ring 3 is pushed up to the catching portion 1 'formed at the point where the flat portion 2 of the column shaft 1 ends, and then the two flat portions 2 of the locking ring 3 are removed. When the caulking portion 11 is formed by caulking as shown in FIG. 3, the fixing of the locking ring 3 is completed. When the column shaft 1 fixing the locking ring 3 as described above is coupled to the bearing 6 together with the inside of the tube 7, the insertion hole 8 of the tube 7 is positioned as shown in FIG.
