| Abstract: | The axle box pull rod of SS7E Electric locomotive was introduced.According to the requirement of speedup,the structure of old product was improved based on the same space envelope and interface dimension.The stiffness and fatigue test results indicated that new structure product could meet the stiffness requirement and had the longer fatigue life,the application results also showed that it could provide the proper primary suspension stiffness and meet high-speed requirement of locomotive. |
