Durable Rail Car Side Beam Component

Side beam is the core load-bearing structural part of the underframe and side wall of subway and high-speed rail car bodies. As a key stressed part of rail transit vehicles, it directly determines the structural strength and operational stability of the whole vehicle, and is widely suitable for the manufacturing scenarios of global urban rail, EMUs and low-floor trams. This product uses high-strength special shaped pipes and profiles as the base material, processed by high-precision cold bending forming technology, and key connection parts are strengthened by welding machining, with high weld strength and no virtual welding, with the core advantages of lightweight, high strength and fatigue resistance, meeting the load transmission needs of modern rail transit vehicles.   In the vehicle body structure, the side beam is seamlessly connected with components such as Door frame assembly and door pillars to build a stable vehicle body bearing frame, which evenly transmits the vibration and…
