The invention relates to the technical field of railway vehicles, and provides a chassis structure and a railway vehicle. The underframe structure comprises an underframe body, and the underframe body comprises at least two cross beams, at least two longitudinal beams perpendicularly fixed to the cross beams and a bearing piece. Wherein a pair of longitudinal beams is arranged between two adjacent cross beams, a first concave area is defined by the cross beams and the pair of longitudinal beams, and supporting surfaces are formed on the upper sides of the pair of longitudinal beams; the bearing piece is fixedly arranged on the lower side of the first concave area and used for forming a first oil storage disc structure in the first concave area. According to the chassis structure and the railway vehicle, the vertical channel area formed by the cross beams and the longitudinal beams can be reasonably utilized, the space occupied by the upper side of the chassis structure when the fuel engine is installed is effectively reduced, the structural design of a vehicle body is more compact and reasonable, and the fuel engine is more convenient to install.
本发明涉及轨道车辆技术领域,提供一种底架结构及轨道车辆。底架结构包括底架本体,底架本体包括至少两个横梁、与横梁垂直固定的至少两个纵梁以及承接件;其中两个相邻的横梁之间设置有一对纵梁,并与一对纵梁围成第一凹陷区,一对纵梁的上侧形成支撑面;承接件固定设置于第一凹陷区的下侧,用于在第一凹陷区形成第一储油盘结构。本发明提供的底架结构及轨道车辆,可以合理利用横梁与纵梁形成的竖向通道区域,有效减小燃油机安装时在底架结构上侧占用的空间,使车体的结构设计更紧凑、合理,并使燃油机的安装更方便。
