摘要
介绍了国内城轨车辆上应用的液压制动夹钳现状,以及应用中存在的问题。针对城轨车辆上应用的液压制动夹钳,设计了一种用于弹簧被动式液压制动夹钳的新型弹簧动力单元装置。通过对弹簧动力单元的功能需求分析,设计出了对应的执行机构,该机构具有输出力功能、常用和辅助液压缓解输出力功能、机械缓解输出力功能以及自动补偿闸片磨耗量功能。阐述了新型弹簧动力单元装置的结构和工作原理,并针对新型弹簧动力单元进行了性能参数的计算和样机试验。试验结果表明,新型弹簧动力单元的功能和技术参数满足设计要求。
The present situation of hydraulic brake clamp applied on urban rail vehicles in China and the existing problems in its application are introduced.A new spring power unit for spring passive hydraulic brake clamp is designed for the hydraulic brake clamp applied on urban rail vehicles.Through the functional requirement analysis of spring power unit,the corresponding actuator is designed.The mechanism has the functions of output force,common and auxiliary hydraulic relief of output force,mechanical relief of output force and automatic compensation of brake wear.The structure and working principle of the new spring power unit are described,the performance parameters of the new spring power unit are calculated and the prototype test is carried out.The test results of the prototype show that the function and technical parameters of the new spring power unit meet the design requirements.
