摘要： A bogie, comprising an articulated mechanism (1), and two side beams (2) which longitudinally extend and are transversely spaced apart, wherein two cross beams (3), which are longitudinally spaced apart, are connected between the two side beams (2); each cross beam (3) comprises a middle section and edge sections located on both sides of the middle section; longitudinal beams (4) are connected between ends, which are located on the same transverse side, of the two middle sections; the articulated mechanism (1) is installed on the two longitudinal beams (4); and at least part of the edge sections are gradually inclined inwards in a transverse direction away from the middle sections. A reduction in a wheelbase of the bogie, and the enhancement of the small-curve passing capacity are facilitated.
