Brake beam of railway vehicle is the most important part of the foundation brake device, mainly to the vehicle braking, the braking force to the brake shoe brake beam passing through, to stop a vehicle.
The combined brake beam is mainly composed of brake beam frame, brake shoe bracket and other parts by universal riveting, bolt fastening and hot set process. According to different brake beam processes, it can be divided into integral forging, integral hot rolling, hot set and other forms.
