Abstract (en)
[origin: EP3492392A1] A bogie includes: a first frame body (10) which includes a right side beam (11) and a first cross beam (12); a second frame body (20) which includes a left side beam (21) and a second cross beam (22); and a bolster (56). The first and second frame bodies (10, 20) support each other in a slidable manner in a longitudinal direction. A center portion of the bolster (56) is supported by a core receiver (30). The bolster (56) and the first cross beam (12) are supported in a flexible manner by a first connecting portion (52A) disposed on the right side of the core receiver (30), and the bolster (56) and the second cross beam (22) are supported in a flexible manner by a second connecting portion (52B) disposed on the left side of the core receiver (30). With such a configuration, fluctuation in lateral force and wheel load at a curved railroad track can be suppressed.
