Abstract

본 발명은, 철도차량용 2차 현수장치의 높이 조정방법 및 장치에 관한 것으로, 특히 철도차량의 차체 높이 조절을 차량과 대차를 분해하지 않고 손쉽게 조절할 수 있는 2차 현수장치의 높이 조정방법 및 장치에 관한 것이다. 본 발명에서는 관통된 스프링 시트(10)의 하단을 통해 승강수단(13)을 이용하여 공기 스프링 (2)과 차체(3)를 상승시키는 공정, 홈부 (15A, 15B) 를 갖는 라이너 (15)를 스프링 시트 (10) 상부로 돌출한 승강수단(13)에 끼우는 공정, 승강수단(13)을 체결수단(12)으로부터 분리하는 공정으로 이루어지는 것을 특징으로 하는 방법을 제공하며, 그의 장치는 통공(11)을 형성시킨 공기 스프링 시트(10)와, 상기 공기 스프링 시트(10)의 통공(11) 하단에 일체로 취부한 체결수단(12)과, 이 체결수단(12)을 통해 승강하여 공기 스프링 (2) 및 차체 (3)를 승강시키는 승강수단(13)과, 스프링 세트(10) 상부로 돌출한 승강수단(13)에 끼울 수 있도록 홈부(15A, l5B)를 형성하는 라이너 (15)로 구성되는 것을 주요 특징으로 한다.The present invention relates to a height adjustment method and apparatus for a secondary suspension device for a railway vehicle, and more particularly, to a height adjustment method and apparatus for a secondary suspension device that can easily adjust the height of a vehicle body without disassembling the vehicle and the bogie. It is about. In the present invention, the step of raising the air spring (2) and the vehicle body (3) using the lifting means 13 through the lower end of the through the spring sheet 10, the liner (15) having the grooves (15A, 15B) It provides a method characterized in that it comprises the step of fitting to the lifting means 13 protruding to the top of the spring sheet 10, the step of separating the lifting means 13 from the fastening means 12, the apparatus is a through hole 11 ) And an air spring (10) which is integrally mounted to the lower end of the through hole (11) of the air spring sheet (10), and the air spring (10) through the fastening means (12). 2) and an elevating means 13 for elevating the vehicle body 3, and a liner 15 forming grooves 15A and l5B to be fitted to the elevating means 13 protruding above the spring set 10. It is to be a main feature.
