In some embodiments, a first reinforcing support portion (not shown) is disposed under the first bottom plate 313, and a second reinforcing support portion (not shown) is disposed under the second bottom plate 323. By providing the first reinforcing support portion and the second reinforcing support portion, the supporting capability of the first bottom plate 313 and the second bottom plate 323 is improved.
As shown in fig. 5-6, in some embodiments, the track beam 300 further includes a connecting baseplate 330. The first beam 310 and the second beam 320 are connected by a connection base 330. The first guide plate 312, the connecting bottom plate 330 and the second guide plate 322 together define the escape route 300 b.
As shown in fig. 2, in some embodiments, the body 210 includes a floor 211, the floor 211 being coupled to an upper end of the suspension 140. The body floor 211, the suspension 140, and the frame 110 collectively define a track beam escape slot 100 a. The rail beam escape groove 100a defined by the body floor 211, the suspension 140 and the frame 110 is used for accommodating a part of the structure of the rail beam 300 (such as the first top plate 311 or the second top plate 321), and when the bogie 100 rolls at a large angle, the part of the structure of the rail beam 300 located in the rail beam escape groove 100a limits the bogie 100, thereby preventing the bogie 100 from rolling over. In some embodiments, the body floor 211 comprises a passenger floor; specifically, the upper portion of the vehicle body floor 211 may form a passenger floor.
As shown in fig. 2, in some embodiments, body 210 further includes a first skirt panel 212 and a second skirt panel 213.
