A car body for a passenger rail vehicle includes a chassis having a front assembly at each vehicle end and a vehicle floor consisting of profiled metal sheet edged in a trapezoidal-like manner within the cross-section, wherein beads of the profiled metal sheet extend in a longitudinal direction of the car body, where the vehicle floor is fixedly connected to each front assembly at transition points to the front assembly via a connecting beam oriented transversely to the longitudinal direction of the car body, where the connecting beam is formed as a profiled metal sheet having a substantially L-shaped cross-section, and where the section of the connecting beam connected to a front assembly is equipped with a trapezoidal-like bead.

Some embodiments of the present disclosure provide a chassis component of a railway vehicle, and a railway vehicle. The chassis component includes two lower boundary beams provided at an interval and a sleeper beam provided between the two lower boundary beams. The sleeper beam includes: a web structure; a center pin, connected with a bogie of a railway vehicle; and a mounting frame, connected with the web structure, the center pin being provided on the mounting frame, the mounting frame including a plurality of vertical plates, and the plurality of vertical plates being provided at an interval along an outer wall surface of the center pin. The technical solution of the present disclosure can solve the problem in the related art of insufficient connecting strength of a center pin and a web structure of a sleeper beam.

A carbody of a railcar includes an underframe, a side bodyshell, and a roof bodyshell. At least one of the underframe, the side bodyshell, and the roof bodyshell includes: an outer plate portion facing a car outside; and a reinforced portion joined to an inside surface of the outer plate portion and forming at least one internal space between the reinforced portion and the outer plate portion. At least one sound absorbing hole communicating with the internal space is formed on the outer plate portion.

A chassis end plate assembly of a railway vehicle is provided, which includes an end plate; a bottom beam arranged at an inner side of a lower edge of the end plate, curved beams arranged at inner sides of two sides of the end plate, a buffer beam located above the end plate; and a reinforcing beam longitudinally arranged between the buffer beam and the bottom beam. The end plate assembly can increase the rigidity of an end portion of the vehicle and improve the vibration mode. The end plate assembly can be combined with an under-vehicle active device compartment so as to form an enclosed space, which may protect pipelines and devices under the vehicle. A railway vehicle provided with the chassis end plate assembly is further provided.
