본고안은 자동차조향기구의 랙베어링에 관한 것으로서, 더욱 상세히는 개선된 향상과 구성의 조향기구의 랙베어링에 관한 것이다.The present invention relates to a rack bearing of an automobile steering mechanism, and more particularly to a rack bearing of a steering mechanism of improved improvement and configuration.
자동차에서 사용되는 랙-피니언 조향기구에 있어서는 랙을 피니언쪽으로 밀어붙이는 부재를 구비하게 되고 종래에는 이러한 부재로서 랙베어링을 사용하게 된다.Rack-pinion steering mechanisms used in automobiles have a member for pushing the rack toward the pinion, and conventionally, rack bearings are used as such members.
종래의 랙베어링은 반원형상 원부체로서 구성하여 랙에 대하여 스프링으로 탄발하면서 접속하도록 되어 있으나, 별도의 윤활구성이 없고 금속재의 재질로서 구성되어 작동시에 마찰에 기인하는 소음이나 발열이 있어 작동의 신뢰성을 저하하고 수명을 단축시키는 요인이 되었었다.Conventional rack bearings are configured as semi-circular cylindrical bodies to be connected to the racks with springs, but they do not have a separate lubrication structure and are made of metallic materials. It has been a factor in lowering reliability and shortening lifespan.
상기와 같은 문제점을 해결하고 조항력의 전달이 원활하도록 접촉성과 재질을 개선한 랙베어링을 제공하는 것이 본고안의 목적이다.Disclosure of the Invention It is an object of the present invention to provide a rack bearing that improves contact and materials so as to solve the above problems and facilitate the transfer of the provisional force.
이하의 부수된 도면과 함게 본고안의 자동차조향기구의 랙베어링을 더욱 상세하게 설명한다.The rack bearing of the automobile steering mechanism of the present invention together with the accompanying drawings will be described in more detail.
제1도는 본고안의 자동차조향기구의 랙베어링이 적용되는 조향기구의 일실시예의 분해사시도, 제2도는 본고안의 랙베어링의 일실시예의 사시도, 제3도 a, b, c는 각각 본고안의 랙베어링의 평면도, 정면도, 저면도로서 함께 설명한다.1 is an exploded perspective view of an embodiment of a steering mechanism to which the rack bearing of the automotive steering mechanism of the present invention is applied, FIG. 2 is a perspective view of an embodiment of the rack bearing of the present invention, and FIGS. 3 a, b, and c are rack bearings of the present invention, respectively. It demonstrates together as a top view, a front view, and a bottom view.
랙(1)이 삽입되는 하우징(2)을 구비하고 랙(1)은 오링(4)과 스프링(5)에 탄발되어 본 고안의 랙베어링(10)에 의하여 부세되면서 하우징(2)에 삽입된다.The rack 1 is provided with a housing 2 into which the rack 1 is inserted into the housing 2 while being pushed by the O-ring 4 and the spring 5 and urged by the rack bearing 10 of the present invention. .
제2도에서 본고안의 랙베어링(10)은 개략 원주체 형상의 보디(11)를 가지며 그 재질은 바람직하게는 폴레아세탈등의 강성수지에 고체 윤활첨가제인 이황화몰리브덴(MoS2)을 첨가하여 사출성형한 것으로 하는 것이 윤활면에서나 가공면에서 좋다.In FIG. 2, the rack bearing 10 of the present invention has a body having a substantially cylindrical shape, and its material is preferably injection molding by adding molybdenum disulfide (MoS2), which is a solid lubricant additive, to a rigid resin such as polyacetal. One should be good in terms of lubrication or processing.
보디(11)는 상방으로 함입한 랙접속부(12)를 가지며 이 랙접속부(12)는 정확히는 반원형상이 아닌 타원상의 원호를 구비한다. 랙접속부(12)는 가로, 세로로 가로질러서 도량형의 윤활부(13)를 가지며 이 윤활부(13)는 다양한 형상으로 그 접속면(14)에 구성될 수 있다.The body 11 has the rack connection part 12 which recessed upwards, and this rack connection part 12 has an elliptical circular arc rather than a semi-circle shape exactly. The rack connection portion 12 has a quantitative lubrication portion 13 transversely and vertically, which may be configured on the connection surface 14 in various shapes.
보디(11)의 저면에는 스프링(5)에 접속하기에 용이한 접속공(15)을 가진다.The bottom face of the body 11 has a connection hole 15 which is easy to connect to the spring 5.
상기 랙접속부(12)와 랙(1)이 접속하는 부분은 제3도 a에서와 같이 두 접속선(FG)에 불과하게 된다. 이것은 각점에서 곡률반경이 상이한 타원형상으로 접속면(14)을 구성함으로서 랙베어링이 랙과는 2개의 선접촉을 하게 되는 것이다.The part where the rack connection part 12 and the rack 1 connect is only two connection lines FG as shown in FIG. This constitutes the connection surface 14 in an elliptical shape with a different radius of curvature at each point, so that the rack bearing has two line contacts with the rack.
상기의 구성의 본고안의 자동차조향기구의 랙베어링은 2개의 접속선으로 랙과 접속하여 접속에 안정성을 제고하고 간섭량을 최소화하며, 외부에서 공급되는 윤활제 및 랙베어링자체의 윤활매제가 윤활성을 보장하여 작동의 신뢰성과 조작의 용이성을 제공하는 유용한 고안인 것이다.The rack bearing of the automobile steering mechanism in this configuration of the above configuration is connected to the rack by two connection lines to improve the stability of the connection and minimize the amount of interference, and the lubricant supplied from the outside and the lubricant of the rack bearing itself ensure the lubricity. It is a useful design that provides reliability of operation and ease of operation.
