The integral welded frame bogie with axle box suspension for railway freight cars is a steering device specifically designed for railway freight cars. It adopts a welded structure design that fully integrates the traditional bolster and side frame, forming a rigid and stable whole. This design method effectively reduces the number of components, improves the overall rigidity and stability, and enhances the load-bearing capacity and durability of the bogie. The overall welded frame type bogie is made of high-quality steel, which has excellent strength and corrosion resistance.
