The present invention relates to an installation structure for a link arm-type axial support apparatus for a railroad vehicle, and more specifically, relates to an installation structure for a link arm-type support apparatus for a railroad vehicle, which has a link arm placed in an axle box of a vehicle wheel to be installed to make a rolling motion towards a truck frame, being able to reduce a ratio of wheel unloading of the vehicle wheel generated when the railroad vehicle drives on a transition section such as a sharp curve or an easement curve, and to increase a derailment safety while the railroad vehicle is driving. According to the present invention, the installation structure for the link arm-type axial support apparatus for the railroad vehicle comprises: a link arm extended towards one side of the axle box placed on a wheel and axle of the railroad vehicle; an elastic joint engaged with a penetrating hole formed on an end unit of the link arm; bushings placed on an upper side and a lower side of a shaft of the elastic joint; and a lower frame placed to cover the bushing placed on a lower side of the shaft of the elastic joint to be fixated and installed on the truck frame of the railroad vehicle.

    본 발명은 철도차량용 링크암방식 축상지지장치 설치구조에 관한 것으로, 보다 상세하게는 차륜의 액슬박스에 구비되는 링크암이 대차프레임에 대하여 롤링(rolling)운동이 가능하도록 설치되어 철도차량이 급곡선이나 완화곡선과 같은 천이구간을 주행하는 경우 발생하는 차륜의 윤중감소율을 저감시킴으로써 철도차량의 주행 시 탈선안전도를 높일 수 있도록 하는 철도차량용 링크암방식 축상지지장치 설치구조에 관한 것이다. 본 발명은 철도차량의 윤축에 구비되는 액슬박스의 일측으로 연장 형성되는 링크암과, 상기 링크암의 단부에 형성된 관통공에 결합되는 탄성조인트와, 상기 탄성조인트의 축 상하부에 구비되는 부쉬와, 상기 탄성조인트의 축 하부에 구비되는 부쉬를 커버하도록 구비되어 철도차량의 대차프레임에 고정 설치되는 하부프레임을 포함하여 이루어지는 것을 특징으로 한다.
