摘要
为了摸清不同工况下制动缓解的理论效果为改进设计提供依据,以货车主流转向架转K2型转向架为研究对象,对制动装置连接副的工况进行抽象建立了3种接触形式的典型工况模型,通过不同工况下制动缓解状态系统受力分析与计算、影响制动缓解的摩擦阻力分析与计算,发现现有制动系统仅靠重力无法实现自动缓解,影响缓解效果的主要因素一方面是基础制动连杆机构连接副的间隙分配不合理导致缓解阻力大,另一方面是制动系统重心提高导致的制动导引滑块下滑摩擦阻力增大.论文在此基础上提出了低成本改善既有制动系统缓解效果的方案与措施.
In order to improve the design ,the mechanism of braking and alleviating of basic braking system in K2 bogie is studied, and three types of working conditions are abstracted for connecting joints of mechanism. Through analyzing and calculating alleviating force as well as main influential factors, it is found that braking system could not alleviate itself. One of the crucial factors is that clearances in mechanisms are not well distributed, which conduces to alleviating resistance increasing. On the other hand, the heightened center of gravity for K2 bogie system leads to fraction resistance of sliding block going up. Base on the above outcomes, the lower cost solutions are proposed for improving alleviating performance of the basic braking system.
