铁道车辆转向架斜楔挡损坏原因分析及改进措施

Damage causes analysis and improvement measures of the railway vehicle bogie inclined wedge block

大型工矿、冶炼企业为了运输需要,均设有自营铁路和自备车辆,在车辆扣修过程中,出现转8A与转8A改台车侧架因斜楔挡开焊、变形、脱落而进库检修。其主要原因为曲线半径、道岔设置不合理,列车运行速度过快,卸车设备调整不当,制造检修工艺不当,改进措施测定曲线最小半径及道岔设置符合规定要求,控制列车技速,改进卸车设备,严格制造检修工艺,达到消除故障、提高车辆质量的目的。

In order to meet the need of the transport ,both the large-scale mining companies and the smelters have the self-supporting railway and the private ears. In the process of repairing the cars,the 8A and the change ear side frame of the 8A are sent to repair be cause of the breaking ,distortion and separation of the inclined wedge block.The main reasons are that the set of curve radius and the turnout are not reasonable, the speed of the train is too fast, the regulation of the unloading equipment is improper and the technique of the manufacture and repair is inappropriate.The improvement measures are put forward by this paper, such as determining the set of the minimum radius and turnout complied with the requirements, controlling the speed of the train, improving the unloading equipmenl and the technique of the manufacture and maintenance so as to overeome the hurdles and improve the quality of the vehicle.
