The invention relates to the technical field of railway vehicles, and provides a bottom frame boundary beam, a vehicle body bottom frame, a railway vehicle body and a railway vehicle. The bottom frameboundary beam comprises a boundary beam body and an equipment pulling and hanging part. The boundary beam body comprises an outer side beam and an inner side beam. The equipment pulling and hanging part is arranged on one side, back to the outer side beam, of the inner side beam; the equipment pulling and hanging part comprises a supporting transverse rib, a shielding longitudinal rib and a connecting inclined rib; and one end of the supporting transverse rib is connected with the inner side beam, the other end of the supporting transverse rib is connected with the bottom of the shielding longitudinal rib, the top of the shielding longitudinal rib is connected with one end of the connecting inclined rib, the other end of the connecting inclined rib is connected with the inner side beam, and the connecting inclined rib, the inner side beam, the supporting transverse rib and the shielding longitudinal rib define an under-vehicle equipment mounting cavity. According to the bottom frame boundary beam provided by the embodiment of the invention, pulling and hanging installation of under-vehicle equipment can be realized, the under-vehicle equipment is effectively prevented from fallingoff, and installation stability and reliability of the under-vehicle equipment are effectively improved.

    本发明涉及轨道车辆技术领域,提供一种底架边梁、车体底架、轨道车辆车体及轨道车辆。该底架边梁包括边梁本体和设备拖挂部,边梁本体包括外侧梁和内侧梁,设备拖挂部设置于内侧梁背向外侧梁的一侧,设备拖挂部包括支撑横筋、遮挡纵筋和连接斜筋,支撑横筋的一端与内侧梁连接,支撑横筋的另一端与遮挡纵筋的底部连接,遮挡纵筋的顶部与连接斜筋的一端连接,连接斜筋的另一端与内侧梁连接,连接斜筋、内侧梁、支撑横筋和遮挡纵筋之间围合形成车下设备安装腔。本发明实施例提供的底架边梁,能够实现车下设备的拖挂安装,有效防止车下设备脱落,进而有效提高了车下设备的安装稳定性和可靠性。
