본 고안은 자동차조향장치의 베어링에 관한 것으로서, 더욱 상세히는 자동차의 조향장치에 채택되는 비 금속성의 베어링의 구성을 개선한 것에 관한 것이다.The present invention relates to a bearing of an automobile steering apparatus, and more particularly, to an improvement in the configuration of a non-metallic bearing adopted in a steering apparatus of an automobile.

자동차의 조향장치는 다수의 샤프트, 컬럼 및 조인트가 체결되어 구성되고 컬럼의 경우는 통상 관재(管材)내부에 컬럼보다는 비교적 직경이 적은 샤프트가 인입되어 조립된다.A steering device of an automobile is formed by fastening a plurality of shafts, columns, and joints, and in the case of a column, a shaft having a relatively smaller diameter than that of a column is usually inserted into a pipe.

이러한 종래의 일반적인 조향장치가 제1도에 분해사시도로서 도시되어 있다.This conventional general steering device is shown in exploded perspective view in FIG.

컬럼(1)내에 샤프트(2)가 삽입, 조립되고 하우징부재(3, 4)가 상하에서 조립되어 케이싱의 역할을 수행하고 통상 상기 샤프트(2)의 단부는 컬럼(1)과 샤프트(2)의 직경차이를 흡수할 수 있는 베어링(5)을 삽입하여 고정지지하고 있다.The shaft 2 is inserted and assembled into the column 1, and the housing members 3 and 4 are assembled up and down to serve as a casing, and the ends of the shaft 2 are generally the column 1 and the shaft 2 The bearing 5 which can absorb the difference in diameter of the insert is inserted and fixed.

상기에서와 같은 베어링(5)은 종래 고무소재로서 제조하여 약간의 탄성을 부여하고 내부의 샤프트(2)와 접속하는 면에는 윤활용의 그리스가 도포되는 나서낭의 홈(Groove)을 가진다.The bearing 5 as described above is manufactured as a conventional rubber material to impart some elasticity and has grooves of the post-bags to which grease for lubrication is applied on the surface to be connected to the inner shaft 2.

그러나, 상기와 같은 구성의 베어링은 장시간의 사용에 의하여 고무가 용이하게 마모되어 버리고 또한 나선상의 홈은 그리스를 외부로 누출시켜버리는 문제점이 있었다.However, the above-described bearing has a problem in that the rubber is easily worn out by long time use, and the spiral grooves leak grease to the outside.

또한 나선상의 내부홈을 가지는 베어링은 금형의 제작이 대단히 어렵고 생산성도 저하된다는 부수적인 문제점이 있었다.In addition, the bearing having a spiral inner groove has a secondary problem that the production of the mold is very difficult and the productivity is also reduced.

상기와 같은 문제점을 감안하여 본 고안의 자동차조향장치의 베어링에서는 개선된 구성을 제공함으로서 용이하게 제조할 수 있고 강도 또한 제고되는 구성의 자동차조향장치의 베어링을 제공하는 것을 목적으로 한다.In view of the above problems, an object of the present invention is to provide a bearing of a vehicle steering apparatus which can be easily manufactured by providing an improved configuration, and also improves strength.

이하의 부수된 도면과 함께 본 고안의 자동차조향장치의 베어링을 더욱 상세하게 설명한다.The bearing of the vehicle steering apparatus of the present invention together with the accompanying drawings will be described in more detail.

제1도는 본 고안의 자동차조향장치의 베어링을 도시하는 예시적인 평면도 및 측면도이다.1 is an exemplary plan view and side view showing a bearing of a vehicle steering apparatus of the present invention.

제2도는 본 고안의 자동차조향장치의 베어링의 반단면상태를 도시하는 사시도, 제3도는 본 고안의 자동차조향장치의 베어링의 조립완성 상태를 도시하는 사시도로서 함께 설명한다.FIG. 2 is a perspective view showing a half sectional state of a bearing of a vehicle steering apparatus of the present invention, and FIG. 3 is a perspective view showing an assembly completion state of a bearing of a vehicle steering apparatus of the present invention.

본 고안의 자동차조향장치의 베어링(10)은 축방향 반절단체의 관상체로서 구성하되 좌측하프(Half : 11)와 우측하프(12)로서 사출성형하고 각각의 접속단면(11', 12')에는 상호 결합하는 돌기(13)와 결함홈(14)을 수개소 구비한다.The bearing 10 of the automobile steering apparatus of the present invention is configured as a tubular body of an axial half body, but is injection molded as a left half (11) and a right half (12), and each connection section (11 ', 12') It is provided with several projections 13 and the defect groove 14 which mutually couple.

또한, 좌측하프(11)와 우측하프(12)의 내면에 형성되는 그리스수납용의 그루우브(15)는 나선상으로 성형하지 않고 반경방향으로 평행한 다수의 원주상홈으로서 구성한다. 상기 각 좌측하프(11), 우측하프(12)의 재질은 고무대신 폴리아세탈을 사용하여 강도를 증대한다.Further, the grooves 15 for grease storage formed on the inner surfaces of the left half 11 and the right half 12 are configured as a plurality of circumferential grooves that are radially parallel without forming in a spiral shape. The material of each of the left half 11 and the right half 12 increases the strength by using polyacetal instead of rubber.

좌측하프(11)와 우측하프(12)는 각각 반절단체로서 성형되어 상기의 돌기(13)와 결합홈(14)이 가이드되어 조립된 뒤 접착등의 방법으로 결합된다.The left half 11 and the right half 12 are each formed as a half-piece, and the protrusions 13 and the coupling grooves 14 are guided and assembled, and then joined by a bonding method.

본 고안의 자동차조향장치의 베어링(10)은 칼럼(1)내부에 삽입되기 때문에 원주방향의 강도는 중요시 되지 않으므로 상기의 공정으로 제조하여도 결합강도에는 영향을 끼치지 아니하게 된다.Since the bearing 10 of the vehicle steering apparatus of the present invention is inserted into the column 1, the strength in the circumferential direction is not important, and thus the coupling strength is not affected even when manufactured in the above process.

이상과 같은 본 고안의 자동차조향장치의 베어링은 조립이 대단히 용이하고 고무대신 폴리아세탈을 사용함으로서 내마모성이 증대되며 좌우하프체로서 구성되어 사출성형 또한 용이한 등의 다양한 장점을 가지는 유용한 고안인 것이다.The bearing of the automotive steering apparatus of the present invention as described above is very easy to assemble, and by using polyacetal instead of rubber, the wear resistance is increased, and it is a useful design having various advantages such as being configured as a left and right half body and also easy to injection molding.
