铁路货车新型橡胶缓冲器设计

Design of a new rubber bumper of railway freight car

介绍了米轨货车橡胶缓冲器—— XJH-1的新型结构方案与设计计算方法。该缓冲器仅由盖板 -橡胶与隔板 -橡胶两个互换性单元构成 ,采用零初压力 ,制造与维修时无须专用装拆设备 ,具有重量轻、冲击力低和缓冲效果好的优点 ;而且安装拆卸方便 ,互换性好 ,制造与维修费用低 ,充分利用了缓冲结构空间 ;为开发大容量提速、高速和重载铁路车辆橡胶缓冲器奠定了基础。

New structural scheme is introduced and design method is presented for a new rubber bumper of the railway freight car with 1 m wide trucks.The bumper is only made up of two exchangeable units,the butt plate rubber unit and the partition plate rubber unit.In addition,a zero initial press force is employed.These make the bumper holds advantages of light in weight, lowest in impact force and good in bumping effect.It is easy to be assembled and disassembled,good in exchangeability,lower in cost of manufacturing and maintaining and higher efficient in use of the bumper volume.The structural scheme provides also a capacity of developing the rubber bumpers used for high speed,sub high speed and heavy railway cars. The design method has been effectively applied to the development of present rubber bumpers.3 tabs,5 figs,10 refs.
