摘　　要：轨道交通车辆的轮对组装大部分采用冷压工艺。由于低地板轻轨车辆齿轮箱结构的特殊性,其轮对需要通过数控轮对压装机进行组装才能满足技术要求。为此,对低地板车辆的轮对组装工艺进行分析,结合轮对结构与数控轮对压装机的接口情况,提出轮对压装新工艺,设计制作低地板车辆轮对压装夹具,使其满足低地板轻轨车辆轮对的压装技术要求。The most wheel-set assembly of rail transit vehicle adopts cold pressing technology. But due to the particularity of low-floor vehicle gearbox structure,it is necessary to assemble the press through the CNC wheel set press to meet the technical requirements of the low-floor wheel-set. In this paper,the wheel set assembly process of low-floor rail vehicles is analyzed. Combined with the structure of the wheel set and the interface of the CNC wheel set press,the new process is developed and researched. A set of low-floor wheel-set press fixture is designed and manufactured to meet the requirements for the wheel-set press of low floor rail vehicles.
