新型米轨机车转向架的选型及设计

Model selection and design of the truck for new model metre-rail locomotive

3B0 轴式转向架机车和 2C0 轴式径向转向架机车均能较好地适应山区小半径曲线线路。从转向架结构、机车动力学及机车总体布置等方面阐述了新型昆明米轨内燃机车转向架的选型。指出 2C0 轴式径向转向架是新型米轨内燃机车转向架更好的选型 ,并介绍了该机车径向转向架的设计。

B 0 and 2C 0 truck locos can all meet the requirement of applying in mountain area with small radius of curve.The truck structure,locomotive dynamic performance and the general layout of the locomotive are taken considerations for model selection of the new type metre rail diesel locomotive truck.2C 0 radial truck is the preferred selection for the new type locomotive.The design of it is presented in this paper.
