종래의 랙피니언 파워기어의 조립 구조도는 도 1에 도시한 바와 같이, 실린더튜브(10),(101)에 랙부쉬(30)와, 랙스토퍼(60)가 분리형으로 랙부쉬(30)를 놓고 랙부쉬(30) 이탈 및 스토퍼의 역할을 하기 위하여 랙스토퍼(60),(601)를 조립후 서클립(70),(701)로 실린더튜브(10)와 랙스토퍼(60),(601)를 고정시키고, 랙부쉬(30)는 부쉬가 앞면에 조립되고, 오일실(50),(501)은 뒷면에 조립되는 구조로 되어 있다.As shown in FIG. 1, the rack bush 30 and the rack stopper 60 are separated from the rack tube 30 in the cylinder tubes 10 and 101, as shown in FIG. After the rack stopper 60 and 601 are assembled to separate the rack bush 30 and serve as a stopper, the cylinder tube 10 and the rack stopper 60 and 601 are provided with the circlips 70 and 701. Fixing, the rack bush 30 is a bush is assembled on the front, the oil chamber 50, 501 has a structure that is assembled on the back.

그런데 이런 종래의 랙피니언 파워기어의 조립구조는 그의 조립구조가 매우 복잡 하여 제작이 용이하지 못하고, 또한 많은 부품소자를 사용함으러써 원가를 상승시키는 문제점등이 야기되었던 것이다.By the way, the assembly structure of the conventional rack pinion power gear is very complicated assembly structure is not easy to manufacture, and also caused the problem of raising the cost by using a large number of component elements.

본 고안은 상기와 같은 종래의 문제점을 해결하고자 이루어진 것으로서, 그 목적은 기존의 랙스토퍼 및 서클립을 삭제하고 랙부쉬와 랙스토퍼를 공용화할 수 있게 하여 원가절감 및 경량화를 꾀할 수 있게 하는데 있다.The present invention is made to solve the conventional problems as described above, its purpose is to delete the existing rack stopper and circlip and to make the rack bush and the rack stopper common to reduce the cost and light weight.

상기의 목적을 달성하고자 본 고안은 랙부쉬에 오일실을 형성하여 랙부쉬의 모든 역활을 수행할 수 있게 하고, 실린더튜브와 랙부쉬에 단차를 주어 랙부쉬의 내부 이동을 방지하도록 구성하며, 상기 랙부쉬에 코킹홈부를 형성하여 실린더튜브 외부로의 이탈을 방지하도록 구성한 것에 특징이 있다.In order to achieve the above object, the present invention forms an oil seal in the rack bush to perform all the roles of the rack bush, and provides a step to the cylinder tube and the rack bush to prevent internal movement of the rack bush. Caulking groove formed in the rack bush is characterized in that configured to prevent the departure to the outside of the cylinder tube.

이를 첨부도면에 의거하여 본 고안을 상세히 설명하면 다음과 같다.When explaining the present invention in detail based on the accompanying drawings as follows.

도 2는 본 고안의 랙피니언 파워기어의 조립구조도로서, 도 2에 도시한 바와 같이, 랙부쉬(80),(801)에 오일실(90),(901)을 형성하여 랙부쉬의 모든 역할을 수행 할 수 있게 구성하고, 실린더 튜브(100),(1001)와 랙부쉬(80),(801)에 단차를 주어 랙부쉬(80),(801)의 내부 이동을 방지하도록 구성하며, 상기 랙부쉬(80),(801)에 코킹홈부(110),(1101)를 형성하여 실린튜브(100),(1001)외부로의 이탈을 방지하도록 구성한 것이다.Figure 2 is an assembly structure of the rack pinion power gear of the present invention, as shown in Figure 2, the rack bush (80, 801) to form the oil chamber 90, 901 in all roles of the rack bush It is configured to perform, and give a step to the cylinder tube 100, 1001 and the rack bush (80), 801 to prevent the internal movement of the rack bush (80, 801), the Caulking grooves 110 and 1101 are formed in the rack bushes 80 and 801 to prevent separation from the outside of the cylinder tube 100 and 1001.

도 3는 본 고안에서의 랙부쉬의 발췌 단면도이고, 도 4는 도 3에서의 코킹홈부의 단면도로서, 본 고안의 작용효과를 바람직한 실시예에 따라 설명하면 다음과 같다.3 is a cross-sectional view of the rack bush in the present invention, Figure 4 is a cross-sectional view of the caulking groove in Figure 3, when explaining the operation of the present invention according to a preferred embodiment as follows.

주지한 바와 같이 기존의 랙스토퍼와 설클립을 삭제하고 랙부쉬와 랙스토퍼를 공용화할 수 있도록 도 2의 구성과 같이 랙부쉬(80),(801)에 오일실(90),(901)을 형성함으로써 랙부쉬(80),(801)의 모든 역할을 수행하도록 하고, 따라서 실린더튜브(100),(1001)와 랙부쉬(80),(801)에 단차를 주므로써 랙부쉬(80),(801)의 내부 이동을 방지하도록 수행한다.As is well known, the oil chambers 90 and 901 are disposed in the rack bushes 80 and 801 as shown in FIG. 2 so that the existing rack stoppers and sulclips can be deleted and the rack bushes and the rack stoppers can be shared. It is formed to perform all the roles of the rack bush (80, 801), and thus by giving a step to the cylinder tube (100), (1001) and rack bush (80), 801 rack bush (80), 801 to prevent internal movement.

또한 상기 랙부쉬(80),(801)에 도 3의 구성과 같이 코킹홈부(110),(1101)를 형성 한 후 실린더튜브(100),(1001)를 코킹함으로써 실린더튜브(100),(1001)외부로의 이탈을 방지하도록 수행한다.In addition, after the caulking grooves 110 and 1101 are formed in the rack bushes 80 and 801 as shown in FIG. 3, the cylinder tubes 100 and 1001 are caulked by the caulking. 1001) to prevent departure.

이와 같이 본 고안은 랙부시에 오일실을 형성하여 랙부쉬의 모든 역할을 수행시키고, 실린더 튜브와 랙부쉬에 단차를 주어 랙부쉬의 내부 이동을 방지시키고, 랙부쉬에 코킹홈부를 형성하여 실린더튜브 외부로의 이탈을 방지시키게 되는 것이다.As such, the present invention forms an oil seal in the rack bush to perform all the roles of the rack bush, and provides a step between the cylinder tube and the rack bush to prevent the internal movement of the rack bush, and forms a caulking groove in the rack bush to form a cylinder tube. It is to prevent departure to the outside.

이상에서와 같이 본 고안은 기존의 랙스토퍼 및 서클립을 삭제하여 랙부쉬와 랙스토퍼를 공용화시킴과 동시에 랙피니언 파워기어의 조립구조가 간단하여 원가절감 및 경량화시킬 수 있는 효과가 있다.As described above, the present invention deletes the existing rack stopper and circlip to make the rack bush and the rack stopper common, and at the same time, the assembly structure of the rack pinion power gear is simple, thereby reducing the cost and reducing the weight.
