Description

一种下置式铁路货车转向架轮对径向装置 技术领域
本发明涉及铁路运输装备技术领域，具体涉及一种铁路货车副构架式径向转向架轮对径向装置的下置结构。
背景技术
现有铁路货车副构架式径向转向架的轮对径向装置一般由前后两个副构架和两根交叉设置的连接杆通过圆销销接组成，副构架置于摇枕两端，连接杆从摇枕中部孔穿过。为了满足车辆下部限界要求，保证转向架其他零部件，尤其是基础制动装置的布置空间；同时也为了降低摇枕的设计难度和保证摇枕结构的紧凑性，副构架式径向转向架主要采用下拉杆的杠杆制动型式。
随着铁路货车技术的不断发展，转向架集成制动装置的应用越来越广泛。现有的副构架式径向转向架因其固有的结构特点，造成其对集成制动装置的适应性不好，与个别型式的集成制动装置无法匹配；同时，由于轮对径向装置的连接杆从摇枕中部孔穿过，两者空间结构交叉，转向架组装工艺难度偏大，且不利于检修维护。
发明内容
本发明目的是公开一种下置式铁路货车转向架轮对径向装置。该装置设计为连接杆从转向架下部，从摇枕、侧架以及基础制动以下穿过结构，其空间结构合理，具有足够的强度和刚度，能较好地适应集成制动装置， 且组装、检修工艺性良好。
本发明通过以下技术方案实现：
一种下置式铁路货车转向架轮对径向装置，所述轮对径向装置由前、后两个副构架和两根交叉设置的连接杆通过圆销连接件销接构成，其特征在于：副构架为承载鞍与横向臂联接组合结构，连接杆布置于摇枕下方构成下置式转向架轮对径向结构；连接杆中心平面高度低于副构架承载鞍鞍面中心平面高度。
上述连接杆中心平面高度为转向架落成后连接杆几何断面中心与轨面的最小垂向距离，承载鞍鞍面中心高度为转向架落成后承载鞍鞍面中心线与轨面的垂向距离。
所述承载鞍由构成弧形鞍结构的鞍面和与鞍面结构一体、竖直设置于鞍面一端的鞍连接臂构成，鞍连接臂设置有多组鞍连接孔和位于中心的鞍锁孔；所述横向臂末端设置有竖直结构的横向臂法兰，横向臂法兰设置多组与鞍连接孔对应匹配的横向臂连接孔和位于中心的横向臂锁舌；副构架通过拉铆钉组件固定连接鞍连接孔与横向臂连接孔、并用锁销将穿过鞍锁孔的横向臂锁舌锁闭构成。
所述鞍连接孔和横向臂连接孔设置三组并成三角形布置。
所述承载鞍一端的鞍连接臂为箱形断面结构。
所述副构架通过设置竖直的鞍连接臂、合适的鞍连接孔位置以及水平布置的横向臂，实现了连接杆整体置于摇枕下方，整体结构工艺性良好。副构架设置箱形断面的鞍连接臂，可以保证在承载鞍鞍面中心与连接杆中 心平面间产生的弯矩作用下，具有足够的强度和刚度。所述连接杆交叉布置，端部嵌入位于副构架的安装槽并通过圆销销接。
所述连接杆端部可设置刚性衬套或弹性铰。
所述圆销与副构架和连接杆间具有小间隙和绕圆销轴线的转动自由度。
与一般轮对径向装置相比，本发明具有以下优点：
1、能较好的适应传统杠杆制动和集成制动装置，有效提高了转向架的通用性，有利于转向架的技术改造和产品升级。
2、轮对径向装置与转向架其他零部件无空间结构交叉，可独立组装，转向架组装工艺性良好。
3、轮对径向装置与转向架其他零部件可通过拆卸挡键直接分离，不破坏其他零部件结构，有效降低了检修维护难度。
