Description
本申请要求于2024年01月12日提交中国专利局、申请号为202410050257.1、发明名称为“一种变轨距转向架轮对”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请涉及轨道机车车辆转向架技术领域,特别涉及一种变轨距转向架轮对。
目前世界上不同国家和地区之间的铁路轨距不尽相同,甚至在某些国家和地区内部,也有多种轨距并存。当同一列车需要在不同轨距的铁路线上跨线运营时,目前有三种处理方式:第一种是转运,即将货箱/乘客从一种轨距的列车转至另一种轨距的列车上;第二种是更换转向架,即将一种轨距的转向架更换为另一种轨距的转向架;第三种是使用变轨距转向架,即转向架在不同轨距线路上跨线时能主动或者被动调整以适应不同的轨距。前两种方式效率低、作业周期长、成本高,第三种则反之。
轨距的变换反映在轮对上,就是车轮在车轴上的轴向位置要发生变换,变轨距转向架的核心要求是车轮能实现解锁和锁紧,车轮解锁后可轴向准确移动到车轴上的预定位置,并且完成移动后能可靠锁紧。目前已有多种变轨技术,但存在结构设计不合理的问题,例如波兰研制了SUW2000变轨距轮对,采用整体轮对结构,轴盘制动,可实现不卸载变轨,但不能带动力;日本开发了A型变轨距转向架,A型变轨距转向架使用轮毂电机、独立旋转车轮结构,不适用于高速。

100的端部。
可以理解的是,连接板300的安装座310穿设过安装槽210后,通过螺栓固定安装孔220与安装座310,使连接板300固定在车轮200上,车轮200和连接板300的位置相对固定。
需要说明的是,车轮200数量为两个,两个车轮200分别和位于驱动装置座110两侧的花键130可移动的连接,每个车轮200对应三个安装槽210和三个连接板300,安装槽210沿车轮200周向均匀分布,安装孔220的数量可根据实际需要进行调整,在本实施例中,每个安装槽210外侧对应六个安装孔220。
支架组件,包括支架500和滑动块600,支架500设有支架件510、支架孔520、定位装置槽530以及导筒座540,支架件510沿车轴100延伸方向的横截面为圆环形,支架孔520为沿车轴100延伸方向贯穿于支架件510的通孔,支架500通过支架件510套设于车轴100,定位装置槽530和导筒座540交替位于支架件510的外周面,滑动块600可移动的穿设于定位装置槽530上的配合孔550。
可以理解的是,支架500通过支架孔520与车轴100上的支架500安装座310过盈配合安装在车轴100上,支架500上的定位装置槽530和导筒座540数量一致,定位装置槽530上设有用于连接滑动块600的配合孔550,在本实施例中,配合孔550的数量和定位装置槽530一致,此外,配合孔550的数量和形状也可根据实际需要进行调整。

位滑块930与滑动块600接触,滑动块600能够推动定位销910与第一定位槽320或第二定位槽330卡接。

本发明在于一种变轨距转向架轮对,包括车轴100、车轮组件、支架组件、轮盘组件、定位装置900、锁紧机构1000、第一密封装置1100和第二密封装置1200。当转向架轮对处于窄轨状态时,滑动块600的倾斜滑动面640推动定位滑块930远离车轴100,使定位装置900的定位销910与连接板300的第一定位槽320卡接,此时导向杆1010的第二限位面1014与导筒1020的第四限位面1023接触,阻止导向杆1010和导筒1020的相对位移,此时,定位装置900、锁紧机构1000位置固定,使车轮组件、支架组件、轮盘组件的相对位置固定;当转向架轮对处于宽轨状态时,滑动块600的倾斜滑动面640推动定位滑块930远离车轴100,使定位装置900的定位销910与连接板300的第二定位槽330卡接,此时导向杆1010的第一限位面1013与导筒1020的第三限位面1022接触,阻止导向杆1010和导筒1020的相对位移,此时,定位装置900、锁紧机构1000位置固定,使车轮组件、支架组件、轮盘组件的相对位置固定;以窄轨状态切换至宽轨状态为例,当转向架轮对需要由窄轨状态切换至宽轨状态时,外力作用于摩擦盘800,带动与摩擦盘800固定连接的过渡盘700克服弹簧1030的
作用力,使过渡盘700带动滑动块600与导向杆1010向靠近驱动装置座110方向移动,此时,滑动块600脱离定位滑块930,使与定位滑块930相连的定位销910在处于压缩状态的定位弹簧920弹力作用下,与第一定位槽320脱离,同时导向杆1010和导筒1020之间的弹簧1030处于压缩状态,实现车轮200解锁,当车轮200达到相应位置时,停止对摩擦盘800作用的外力,此时在压缩状态的弹簧1030的作用下,轮盘组件和导向杆1010沿远离驱动装置座110的方向移动,此时会带动与过渡盘700连接的滑动块600沿同样方向移动,当滑动块600的倾斜滑动面640与定位滑块930的楔形滑动面931接触,使定位装置900与连接板300的第二定位槽330卡接,使整个轮对系统处于宽轨状态;除此之外,锁紧机构1000的导向杆1010具有第一限位面1013和第二限位面1014,锁紧机构1000的导筒1020具有第三限位面1022和第四限位面1023,第一限位面1013、第二限位面1014、第三限位面1022和第四限位面1023用来限制导向杆1010和导筒1020的相对位移,第一密封装置1100和第二密封装置1200用来防止运行过程中杂质和异物进入定位装置900和锁紧机构1000。如此设置的变轨距转向架轮对,能够避免轮对系统结构设计不合理的问题。
