Description

窄轨客车转向架
技术领域
本发明涉及一种使用在米轨线路上的、速度等级为120km/h的铁路客车转向架。
背景技术
目前国内准轨转向架体系已较为完善，但缺少对米轨转向架的研制开发，米轨转向架种类少，速度等级低，结构复杂，维修量大，而且多为踏面制动。
东南亚国家的铁路客车轨距基本为米轨，并且市场越来越多，但对车辆的要求也越来越高，传统的米轨车辆已不能满足要求。针对米轨市场需要，研发一种速度快，结构简单，维修量小，安全舒适的米轨客车转向架很有必要，结合泰国115辆米轨客车项目合同要求，充分借鉴现有准轨转向架转向架优良结构，通过对结构、参数的优化设计，研制一种120km/h速度等级的米轨客车转向架。
发明内容
本发明的目的是研制一种适用于米轨（轨距1000mm）、最高运行速度120km/h、轴盘制动的铁路客车转向架，同时转向架要能够随整车起吊、能够在不分解转向架的情况下快速更换轮对。
为实现上述目的，本发明提供一种窄轨客车转向架，包括构架、轮对轴箱装置、中央悬挂装置和基础制动装置组成，其特征在于：
（1）构架：横梁与侧梁采用锻件连接，纵向梁上设有横向缓冲和垂向起吊一体的止挡座；
（2）轮对轴箱装置：采用转臂定位方式，通过钢弹簧和垂向减振器缓冲轮轨冲击和振动，垂向减振器同时具有起吊功能，轴箱采用三体式结构，实现不分解转向架快速更换轮对。
（3）中央悬挂装置：单拉杆牵引，空气弹簧悬挂，同时设有二系横向减振器和抗蛇行减振器；
（4）基础制动装置：采用轴装的盘型制动单元，每辆车都有一个制动单元具有手制动功能。
本发明研发一种速度快，结构简单，维修量小，安全舒适的米轨客车转向架很有必要，结合泰国115辆米轨客车项目合同要求，充分借鉴现有准轨转向架转向架优良结构，通过对结构参数的优化设计，研制一种120km/h速度等级的米轨客车。
附图说明
图1是本发明的转向架结构示意图。
具体实施方式
参照图1，本发明的转向架主要由以下几部分组成：由侧梁、横梁、纵向梁和各种吊座组焊而成的构架组成1；由轮对、轴箱和弹簧减振元件组成的轮对轴箱装置2；中央悬挂装置3；由制动单元和制动盘组成的基础制动装置4；构架组成1是装配其它各零部件的基础，轮对轴箱装置2将车轮的滚动运动转换为转向架的水平运动，同时缓冲来自轨道的冲击和振动，中央悬挂装置3通过牵引拉杆传递车体和转向架之间的牵引力和制动力，通过空气弹簧提供车体的垂向支撑及阻尼，通过横向减振器提供横向阻尼，通过抗蛇行减振器5抑制车辆的蛇行运动，基础制动装置4提供车辆所需制动力。
