The present invention relates to an axial rubber spring assembly structure for a railway vehicle, which has an elastic liner having elasticity between an axle box and an axial rubber spring of a railway vehicle, thereby being possible to maintain initial rigidity of the axial rubber spring by rigidity of the elastic liner and being possible to improve derailment safety and driving safety of the railway vehicle. The present invention includes: an axial rubber spring installed between an axle box and a bogie frame of a railway vehicle; an elastic liner provided between the axle box and the elastic rubber spring and having elasticity; and a lower fixing bracket penetrating the axle box and coupled to the axial rubber spring.

    본 발명은 철도차량용 축상고무스프링 조립체 구조에 관한 것으로, 철도차량의 액슬박스와 축상고무스프링의 사이에 탄성을 가지는 탄성라이너를 구비함으로써 탄성라이너의 강성에 의해 축상고무스프링의 초기 강성을 유지할 수 있도록 하여 철도차량의 탈선 안전도 및 운행 안전성을 향상시킬 수 있도록 하는 철도차량용 축상고무스프링 조립체 구조에 관한 것이다. 본 발명은 철도차량의 액슬박스와 대차프레임 사이에 설치되는 축상고무스프링과, 상기 액슬박스와 축상고무스프링의 사이에 구비되되, 탄성을 가지는 탄성라이너와, 상기 액슬박스를 관통하여 축상고무스프링에 결합 설치되는 하부고정브라켓을 포함하여 이루어지는 것을 특징으로 한다.
