20 30 40T Railway Bogie Frame For Highway Maintenance
20-40T Axle Load AAR M-201 Railteco Bogie Side Frame
1 . Description with 20-40T Bogie Side Frame:
20-40T Bogie Side Frame is an important bearing component of the railway freight car bogie. Bogie Side Frame is not only related to the performance of the bogie, but also related to the safety of railway transportation. Side frame is to connect two wheelsets and transfer the weight of the car body from the bolster and suspension system to the wheels and rails.
In the past 20 years, my country's side frame design and manufacturing technology has been greatly improved, and Bogie Side Frame quality has also been continuously improved. The main functions of the bogie side frame are as follows:
