Description

转向架内置橡胶关节端梁结构 技术领域
本发明涉及机车转向架技术领域。
背景技术
转向架构架端梁相对于构架其它部位振动加速度较大。以往端梁与构架之间采用焊接型式或螺栓紧固型式安装(均为刚性连接)。在轨道线路状况不好的情况下，采用焊接型式和螺栓紧固型式的端梁安装方式，容易因长期振动产生疲劳损伤破坏焊缝或紧固螺栓，严重的情况下导致端梁脱落造成车辆脱轨，影响车辆行车安全。针对菲律宾项目以下情况需对构架端梁结构设计进行优化：
1.菲律宾铰接转向架电机-齿轮箱组成采用全悬挂型式安装，约1/3的质量作用于构架端梁处，增加端梁承载；
2.构架端梁安装有液压控制单元及配套液压管路，增加端梁承载；
3.菲律宾项目线路使用频繁，但多年未经检修，轨道表面存在大量磨耗和剥离情况，线路状况很差。
以上三点原因加剧了构架端梁在车辆运行过程中所受振动冲击影响。
发明内容
本发明所解决的技术问题是提供一种能够地勘车辆运行过程中所受振动冲击的转向架内置橡胶关节端梁结构。
本发明采用的技术方案是一种转向架内置橡胶关节端梁结构，包括两个圆筒状固定座，两个固定座之间设有一道横梁，横梁与固定座之间通过连接销轴相固定，连接销轴的前端套在固定座内部，固定座设有橡胶关节，橡胶关节内为连接销轴的前端，连接销轴和固定座的端面通过螺栓和防松垫圈进行轴向把紧，固定座与转向架构架端梁相适配。
横梁采用方管、圆管型材为主体。
本发明的有益效果是解决了现有刚性连接方式(焊接、螺栓紧固)端梁结构在线路状况较差，端梁长期振动产生疲劳损伤和应力集中破坏焊缝或螺栓和的问题，利用橡胶元件特性消除因振动造成的疲劳损伤和应力集中问题；同时结构便于拆装维护。

图2为焊接安装方式构架端梁。
图3为本发明的内置橡胶关节端梁结构示意图。
图4为图3中沿A-A方向剖视图。

图中标记为：1-连接销轴，2-端盖，3-橡胶关节，4-螺栓，5-防松垫圈，6-固定座，7-横梁。
具体实施方式
下面结合附图对本发明作进一步说明。
在端梁固定座6内部设置橡胶关节3，横梁7通过连接销轴1与固定座6连接。连接销轴另一端使用端盖2和紧固件螺栓4、防松垫圈5把紧，将固定座6和横梁7组成一体。该结构端梁通过内置橡胶关3消除以往刚性连接端梁结构受振动冲击造成的疲劳损伤和应力集中；橡胶关节3内置于固定座6内可有效避免紫外线、高温、雨水等原因损伤橡胶关节3降低其性能，保障橡胶关节3的使用寿命；本发明的端梁组成仅需通过螺栓安装在构架端部，无需在构架端部设置其它安装座或设备，便于日常检修维护，降低相关人力及设备成本。
通过内置橡胶关节消除以往刚性连接端梁结构受振动冲击造成的疲劳损伤和应力集中；避免在菲律宾热带气候条件下紫外线、高温、雨水等原因损伤橡胶关节降低其性能，保障橡胶关节使用寿命；避免车辆在运行过程中端梁因线路状况差产生损坏造成安全事故和日常检修维护因橡胶关节老化性能降低更换橡胶关节，保障橡胶关节使用寿命，降低使用维护成本。
其中,横梁7采用方管、圆管型材为主体和齿轮箱吊座、液压控制单元安装座等组焊而成，组焊后进行热处理和探伤保证焊接质量，最后端梁进行整体加工以保证安装定位尺寸精度。
橡胶关节3内置于固定座6内可有效避免紫外线、高温、雨水等原因损伤橡胶关节降低其性能，保障橡胶关节使用寿命；端梁通过内置橡胶关节消除以往刚性连接端梁结构受振动冲击造成的疲劳损伤和应力集中。
