Abstract: 본 발명은 버스의 조향장치에 사용되는 링크기구에 관한 것이다. 본 발명에 따른 조향장치의 링크기구는 슬래브아암(11)이 사이드프레임(7)에 고정되어 하방으로 연장하는 슬래브아암제어용 브라켓(20)의 하단에 힌지되어 제 1 드래그링크(4)에 의해 중립의 상태로부터 좌,후로 하향하여 작동하도록 구성된 것이다. 또한, 제 2 드래그링크(12)의 형상도 슬래브링크(11)의 하향피벗운동에 따라 휠(9)을 조향하도록 선단이 상방으로 경사져 연장하도록 형성되며, 종단은 하방으로 경사져 연장하도록 형성된다.
본 발명에 따른 조향링크에서는 슬래브아암(11)의 위치가 낮아지며, 더욱이 슬래브아암(11) 및 제 2 드래그링크(12)가 하방으로 회전하여 조향이 이루어지므로 차량 하부의 다른 부품들과의 간섭의 우려가 없게 되며, 조향시 링크기구의 무게중심이 제 1 드래그링크(4)의 하방에 위치하게 되므로 조향휠(1)에 큰 반력을 미치지 않게 되어 스티어링휠(1)의 떨림현상이 방지되게 된다. 이에따라, 차량의 롤링현상이 저감되어 승차감의 향상에도 기여할 수 있다.
