Research on replacement technology of axle box spring of Type 206P bogie
In the running process of railway vehicles,the wheel set of the bogie,the axle box spring,the bolster spring and other parts of the bogie may fail,and the fail parts shall be replaced in time.In order to optimize the technological process and make the replacement of the faulty parts more efficient and faster,the technological process of replacing the axle box spring of the bogie was optimized in view of the non-frame working condition of the axle box spring of the bogie.The test results showed that by adopting the optimized process flow,the car body and one end of the frame could be lifted manually and the axle box spring could be replaced under the condition of no lifting machine on common rail.It provides new technical support for replacing the faulty parts such as the temporary maintenance axle box spring of the bogie.
