机车径向转向架设计原理

ON THE DESIGN PRINCIPLES OF A SELF-STEERING POWERING BOGIE

根据对机车径向转向架的基本要求，从导向机理、牵引与导向功能的关系、轮对耦合方式、轮对相对于构架的位置、机构活动度、关节参数的重要性、等效模型及其施力方式、结构复杂程度等方面，分析了机车径向转向架的特点，指出了与车辆径向转向架的区别，并提出了相应的设计原则。为确保机车径向转向架的试制成功，必须加强机理研究，注重分析计算，精心设计结构，并重视各种试验。

According to the basic requirements of a radial bogie with power and from severalpoints of view such as:guidance mechanism ,relationship between traction and guidance,connected way of wheelsets on a bogie,wheelset positions in a bogie,freedoms of radical mechanism,influence of link parameters,equivalent analysis model and the execution offorces on it,complexity of bogie structure,etc.,in this paper,the characteristics of self-steering powering bogie are analysed,the differences between self-steering bogies with andwithout power are pointed out,and the relavent design principles are proposed.It is considered that the mechanism study,the analysis calculations and the experiments of radial mechanism should be specially emphasized to make sure the success of a functional self-steeringpowering bogie.
