Abstract:
Provided is a railway vehicle, comprising a vehicle body and a bogie provided below the vehicle body. The bogie comprises a framework, a wheel set (4) provided below the framework, a traction device (7) provided on the framework, a brake device (9), and a secondary suspension device (6). The framework comprises two side beams (1) arranged in parallel, cross beam mounting holes, a cross beam and a limiting member, wherein the side beams (1) extend in a longitudinal direction; the cross beam mounting holes are formed in the middles of the side beams (1), each cross beam mounting hole is a through hole, the center line of each cross beam mounting hole extends in the transverse direction, and the longitudinal direction and the transverse direction are two horizontal directions perpendicular to each other; the cross beam (2) extends in the transverse direction, two ends of the cross beam (2) penetrate through the cross beam mounting holes in the two side beams (1) respectively, and relative displacement can be generated between the cross beam and the side beams (1) in the transverse direction; the length of the cross beam (2) is greater than the distance between the outer side surfaces of the two side beams (1); and the limiting member is provided between the cross beam (2) and the side beams (1) and used for limiting the relative displacement between the cross beam and the side beams (1) within a preset range. The railway vehicle can pass through a route with a small curvature radius.
