The embodiment of the invention relates to the technical field of railway vehicles, in particular to a roof and a body of a railway vehicle. The roof comprises a flat top structure with a rectangularopening, the flat top structure comprises two parallel flat top end beams and two parallel flat top longitudinal beams, and the flat top longitudinal beams are fixedly connected between the two flat top end beams; the rectangular opening is defined by the flat-top end beam and the flat-top longitudinal beams; each flat-top longitudinal beam comprises a flat-top pipe and a flat-top plate fixedly connected to the top of the flat-top pipe. The flat top end beam, the flat top pipe and the flat top plate are all of an integrally-formed structure. The roof can meet the requirements for large openings and heavy loads, meanwhile, the welding workload and welding deformation can be reduced, subsequent part assembling is facilitated, and therefore the assembling efficiency is improved.

    本申请实施例涉及轨道车辆技术领域,具体地,涉及一种轨道车辆的车顶和车体。该车顶包括具有矩形开口的平顶结构,所述平顶结构包括两个平行设置的平顶端梁以及两个平行设置的平顶纵梁,所述平顶纵梁固定连接在两个所述平顶端梁之间;所述矩形开口由所述平顶端梁和所述平顶纵梁围绕形成;所述平顶纵梁包括平顶管和固定连接于所述平顶管顶部的平顶板;所述平顶端梁、所述平顶管以及所述平顶板均为一体成型结构。该车顶在满足大开口、重荷载要求的同时,还能减少焊接工作量和焊接变形,方便后续部件装配,从而提高装配效率。
