随着广州地铁车辆运营公里数的增加 ,车辆的故障类型及数量逐渐增多 ,修理的级别不断提升 ,转向架与车体的分离、连接作业也越来越频繁。因而 ,在转向架分离、连接作业时对车辆中心销、空气弹簧及抗侧滚扭杆等部件的对位连接原理和方法进行科学分析 ,并且进行合理的工艺布置 , With the increase of the number of kilometers operated by Guangzhou Metro vehicles, the types and quantities of vehicles have been gradually increased, the level of repairs has been continuously improved, and the separation of the bogie and the vehicle body has made the connection work more and more frequent. Therefore, during the bogie separation and connection work, the principle and method of alignment connection of the vehicle center pin, the air spring and the anti-roll bar and other components are analyzed scientifically, and the reasonable process layout is carried out.
