AI Technical Summary
The existing U-shaped frame of the radial mechanism of railway freight car wheel axle has a large impact force when connected to the connecting rod, resulting in insufficient operational reliability and inconvenient maintenance.
A U-shaped frame is designed, including radial arms and connecting arms. By setting reinforcing rings and bushings at the mounting holes to form mounting grooves, the connection of the connecting rods is optimized, the impact force is reduced, and the stability is improved through bending structure and integral frame structure.
It effectively reduces the impact force between the connecting rod and the U-shaped frame, improves operational reliability, and facilitates connection and maintenance with the load-bearing saddle.
