It came with the body to bear the dynamic load transfer group, traction force, braking force, locomotive in orbit. Therefore traction bogie requires sufficient strength, small wheel rail force, better stability, stability and high performance through the curve, adhesion rate, traction and reliable braking performance, and meet the requirements of standardization, simplification. With the development of economy and science and technology progress of high speed EMU in China will have to To use more widely. The electric locomotive bogie is supporting the foundation, its performance has a great influence on the running safety of locomotive. So it is very necessary to study the standard of high speed bogie locomotive, and standardization is the technical foundation of integrated work, through the development and implementation of the organization the standard, can effectively ensure and improve the product quality and the quality of the project, technical standards organization of modern production and trade, is an important part of scientific management.
