The invention relates to the field of railway vehicles, and provides a vehicle underframe and a railway vehicle. The vehicle underframe comprises a side beam and a supporting and hanging cross beam; the supporting and hanging cross beam is suitable for being installed on the edge beam through an installation structure and comprises a beam body and a supporting and hanging body which are connected with each other, a first reinforcing rib with a reinforcing structure is arranged on the side, away from the supporting and hanging body, of the beam body, and the supporting and hanging body is suitable for supporting and hanging under-vehicle equipment. According to the chassis, the supporting and hanging cross beam is arranged in the form that the beam body and the supporting and hanging body are connected, so that the structure of the supporting and hanging cross beam is further simplified. The first reinforcing rib with the reinforcing structure is arranged on the side, away from the supporting and hanging body, of the beam body, so that the structure of the beam body can be further optimized, the loading capacity of the beam body can be effectively improved, and supporting and hanging of equipment under a large vehicle are achieved. And the first reinforcing ribs with the reinforcing structures are arranged, so that the impact resistance of the beam body in the length direction of the vehicle can be improved. In addition, the beam body also has the advantages of simple structure and light weight.
本发明涉及轨道车辆领域,提供一种车底架及轨道车辆。车底架,包括边梁和托挂横梁;托挂横梁适于通过安装结构安装于边梁,托挂横梁包括相互连接的梁体和托挂体,梁体背离托挂体的一侧设置有带补强结构的第一加强筋,托挂体适于托挂车下设备。该车底架通过将托挂横梁设置呈梁体和托挂体相连的形式,使得托挂横梁的结构进一步地简化。通过在梁体背离托挂体的一侧设置带补强结构的第一加强筋,能够进一步地优化该梁体的结构,进而能够有效地提升梁体的载重能力,实现大型车下设备的托挂。而且通过设置带补强结构的第一加强筋,还能够提升该梁体沿车长方向的抗冲击能力。此外,该梁体还具有结构简单、可轻量化的优点。
