The invention discloses a subway vehicle, which is characterized in that a vehicle body comprises a uniform-section full-length arc vehicle roof (1) and a bottom frame (13), and vehicle roof equipment is arranged in the longitudinal middle of the vehicle roof (1); the bottom frame (13) comprises short floors (133 and 134), a sleeper beam (141) and a long floor (131) which are connected in sequence, and the upper surface of the sleeper beam (141) is flush with the upper surfaces of the long floor (131) and the short floors (133 and 134); and a central traction pin (21) is fixedly connected below the sleeper beam (141). The arc roof with the full-length cross section is adopted, so that the structure of the roof is simplified, and the weight of a vehicle body is reduced; the roof equipment is arranged in a centralized mode, aerodynamic resistance is reduced, a bottom frame of a vehicle body is of a sectional structure, connection of a sleeper beam and a floor is further strengthened, the adverse effect that the rigidity of the whole vehicle is reduced due to the fact that a micro-arc top is adopted is overcome, and it can be guaranteed that the vehicle body is not damaged after being used for a long time.
本发明公开了一种地铁车辆,其特征在于,车体包括等截面通长圆弧车顶(1)和底架(13),所述车顶(1)纵向的中部设置有车顶设备;所述底架(13)包括依次连接的短地板(133、134)、枕梁(141)和长地板(131),所述枕梁(141)的上表面与所述长地板(131)、短地板(133、134)的上表面平齐;所述枕梁(141)下方固定连接有中心牵引销(21)。本发明采用截面通长圆弧车顶,有利于简化车顶的结构,降低车体的重量;车顶设备采用集中式布置,降低气动阻力,车体的底架采用分段式结构,枕梁与地板的连接得到进一步的加强,克服了采用微圆弧顶带来整车刚度下降的不利影响,能确保车体长期使用不损坏。
