자동차의 현가장치용 로워암 장착구조Lower arm mounting structure for suspension of vehicle

본 발명은 자동차의 현가장치에 관한 것으로서, 특히 자동차의 현가장치용 로워암 장착구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension apparatus for a vehicle, and more particularly to a lower arm mounting structure for a suspension apparatus of an automobile.

자동차의 현가장치용 로워암은 자동차의 크로스멤버와 자동차의 조향너클 사이에 장착되어 바퀴에서 발생되는 제동력이나 선회구심력을 회전지지하는 자동차현가장치의 주요구성부품이다.The lower arm for suspension of a vehicle is a main component of an automotive suspension device which is mounted between a cross member of an automobile and a steering knuckle of a vehicle and rotatably supports a braking force or a turning center force generated from the wheel.

종래에 사용되어 온 자동차의 현가장치용 로워암 장착구조를 제1도와 관련하여 설명하면 다음과 같다. 우선 구성을 보면 다음과 같다. 참조번호 1은 크로스멤버를 지시한다. 상기 크로스멤버(1)의 단부에는 브라켓1(2), 브라켓2(3) 및 브라켓3(4)가 형성되어 있다. 상기 크로스멤버(1)의 브라켓들(2, 3, 및 4)에는 볼트(5)와 클램프(6)에 의해 로워암(7)이 장착되되 상기 로워암(7)의 크로스멤버측 지지부중 하나는 부쉬형 지지부(7-2)로 되어 있으며 또한 다른 하나는 로드형 지지부(7-3)로 되어 있다.A lower arm mounting structure for a suspension of a vehicle which has been conventionally used will now be described with reference to FIG. First, the configuration is as follows. Reference numeral 1 indicates a cross member. A bracket 1 (2), a bracket 2 (3), and a bracket 3 (4) are formed at the end of the cross member 1. The lower arm 7 is mounted on the brackets 2, 3 and 4 of the cross member 1 by bolts 5 and clamps 6 and one of the cross member side supports of the lower arm 7 Shaped supporting portion 7-2 and the other is a rod-shaped supporting portion 7-3.

전술한 종래에 사용되어 온 자동차의 현가장치용 로워암 장착구조에 있어서, 그 구성이 복잡하여 제조와 조립이 어려워서 제조원가가 많이 드는 한편 그 중량이 많이 나가게 되며, 또한 크러스멤버에 직접 장착하는 관계상 그 비틀림강성과 전후강성이 취약해지는 문제점이 있었다.In the lower arm mounting structure for a suspension of an automobile which has been conventionally used, it is difficult to manufacture and assemble because of its complicated structure, so that the manufacturing cost is large and its weight becomes large. In addition, There is a problem that the torsional rigidity and the longitudinal rigidity become weak.

본 발명은 전술한 종래의 문제점을 해결하기 위해서 제안된 것으로서, 본 발명의 목적은, 그 구성을 단순화해서 제조와 조립이 용이하게 하여 그 제조원가를 절감하는 한편 그 중량을 줄여주며, 또한 별도의 브라켓에 장착하여 그 비틀림강성과 전후강성을 증대시키기 위한 것이다.SUMMARY OF THE INVENTION The present invention has been proposed in order to solve the above-described problems of the prior art. It is an object of the present invention to simplify the construction and simplify manufacturing and assembling to reduce the manufacturing cost thereof, So as to increase the torsional rigidity and the longitudinal stiffness.
