The brake beam transmits braking force from the brake cylinder to the brake shoes, ensuring even pressure distribution across the braking surface.
Common materials include carbon steel, alloy steel, and cast iron, with material grades such as Q235B to Q345B.
The rated braking force typically ranges from 20 to 80 kN, but the exact value depends on the vehicle's braking capacity requirements.
Directory values are reference ranges. Actual dimensions, materials, and performance must be confirmed with the legal manufacturer or supplier for the specific model and application.
