본 고안은 조향장치의 랙-밸브하우징어셈블리에 관한 것으로서, 더욱 상세히는 동력 조향장치에서의 밸브하우징과 랙하우징을 접속하는 구성의 개선에 관한 것이다.The present invention relates to a rack-valve housing assembly of a steering apparatus, and more particularly, to an improvement of a configuration for connecting a valve housing and a rack housing in a power steering apparatus.
자동차에서의 동력조향장치는 유압구동수단을 구비하여 적은 힘으로도 핸들을 조작할 수 있게하는 구성부재로서 랙하우징에 체결되는 밸브하우징으로 유압이 인가되도록 구성된다.The power steering device in a vehicle is provided with hydraulic driving means and configured to apply hydraulic pressure to a valve housing which is fastened to a rack housing as a component that allows the steering wheel to be operated with a small force.
이러한 양분된 랙하우징과 밸브하우징을 체결하기 위하여 종래에는 랙하우징에 나사공을 천공하여 볼트로서 상호 체결하였지만, 조립공정이 복잡하고 접속부에서의 유압의 누출이 발생하는 등의 문제점이 있었다.In order to fasten these divided rack housings and valve housings, conventionally, screw holes were drilled into the rack housings and fastened to each other as bolts. However, the assembly process is complicated and hydraulic leaks occur at the connecting parts.
상기와 같은 문제점을 해결하기 위하여 개선된 구성의 조립방법이 적용되는 조향장치의 랙하우징 튜브어셈블리를 제공하는 것을 본 고안의 목적으로 한다.It is an object of the present invention to provide a rack housing tube assembly of a steering apparatus to which an assembly method of an improved configuration is applied to solve the above problems.
이하의 부수된 도면과 함께 본 고안의 조향장치의 랙하우징어셈블리를 더욱 상세하게 설명한다.The rack housing assembly of the steering apparatus of the present invention together with the accompanying drawings will be described in more detail.
제1도는 본 고안의 조향장치의 랙-하우징어셈블리를 도시하는 측면도, 제 2 도는 본고안의 조향장치의 랙-밸브하우징어셈블리를 도시하는 단면도로서 함께 설명한다.FIG. 1 is a side view showing the rack-housing assembly of the steering apparatus of the present invention, and FIG. 2 is a cross-sectional view showing the rack-valve housing assembly of the steering apparatus of the present invention.
랙하우징(1)에 삽입되는 유압작동용의 밸브하우징(2)을 구성함에 있어서, 밸브하우징(2)의 하단부를 상기 랙하우징(1)에 삽입되기전에 적합한 축소관체의 형상을 가지고 밸브하우징(2)의 하단부 외방에는 외벽부를 둘러싸는 요홈(凹홈)형상의 사출고정홈(3)을 형성한다.In constructing the valve housing 2 for hydraulic operation inserted into the rack housing 1, the lower end of the valve housing 2 has a shape of a reducing tube suitable for insertion before being inserted into the rack housing 1. At the outer side of the lower end of 2), an injection fixing groove 3 having a groove shape surrounding the outer wall part is formed.
상기 사출고정홈(3)은 밸브하우징(2)의 외방벽부에 형성된 링형상의 오목한 홈이다.The injection fixing groove 3 is a ring-shaped concave groove formed in the outer wall portion of the valve housing 2.
상기 밸브하우징(2)의 랙하우징(1)으로의 압입시에 사출고정홈(3)의 대응하는 랙하우징(1)위치에는 도시한 바와 같은 외방개구(4)를 일부 형성한다. 외방개구(4)는 도시하는 바와 같은 관통공일 수있을 것이다.At the time of the press fitting of the valve housing 2 into the rack housing 1, a part of the outer opening 4 as shown in the drawing is formed at the corresponding rack housing 1 position of the injection fixing groove 3. The outward opening 4 may be a through hole as shown.
랙하우징(1)의 외방개구(4)와 밸브하우징(2)의 사출고정홈(3)은 압입조립시에 개략 일치하는 위치에 있게 된다.The outward opening 4 of the rack housing 1 and the injection fixing groove 3 of the valve housing 2 are in roughly coincident positions during the press fitting assembly.
상기와 같은 구성의 랙하우징(1)에 밸브하우징(2)을 압입하여 끼운 뒤 상기 외방개구(4)로 사출성형하여 (→ 부위) 사출되는 소재가 외방개구(4)와 사출고정홈(3)을 채움으로서 고정되는 구성이 된다.The valve housing 2 is press-fitted into the rack housing 1 having the above-described configuration, and then injection molded into the outer opening 4 (→ site), and the material to be injected is the outer opening 4 and the injection fixing groove 3. ) To be fixed.
사출시에 사용되는 소재는 강성의 금속재의 하우징소재와 결합성이 우수한 고점성의 강성수지인 것이 바람직하다.It is preferable that the material used at the time of injection is a highly viscous rigid resin having excellent bonding properties with the housing material of the rigid metal material.
이상과 같은 본 고안의 조향장치의 랙하우징어셈블리는 종래 볼트체결구성을 사출구성으로 변경함으로서 강고한 결합이 이루어지고 또한 결합부에서의 밀봉성이 제고되어 종래와 같은 문제점을 일소하여 조립성 및 기밀성이 제고되는 유용한 고인이 것이다.The rack housing assembly of the steering apparatus of the present invention as described above has a strong coupling by changing the conventional bolting configuration into an injection configuration, and also improves the sealing property at the coupling part, eliminating the problems as in the prior art, and assembling and airtightness. This would be a useful deceased.
