| Abstract: | HX_D3 is 6-axle,7200kW high power AC—driven main line electrical locomotive widely operated in china.Since put into application in 2007,many wheel flats occurred to HX_D3 locomotives in operation due to spring stopping brake device failure,which seriously affected normal operation of locomotives and shorten the life of wheel-sets.Based on principle of design,control system and operation conditions of spring stopping brake device on HX_D3 locomotives,the reason for wheel tread spalling caused by action of spring stopping brake device is thoroughly analyzed.Counter meansures are proposed which lead to good results after implementation. |
