Title:
BOGIE FOR RAILROAD CAR, AND RAILROAD CAR PROVIDED WITH BOGIE
Document Type and Number:
WIPO Patent Application WO/2018/020980
Kind Code:
A1
Abstract:
This bogie comprises: a first frame body (10) which includes a right-hand side beam (11) and a first lateral beam (12); a second frame body (20) which includes a left-hand side beam (21) and a second lateral beam (22); and a bolster (56). The first and second frame bodies (10, 20) support each other slidably in the longitudinal direction. The center of the bolster (56) is supported by a core receiver (30). The bolster (56) and the first lateral beam (12) are flexibly supported by a first connection portion (52A) disposed on the right side of the core receiver (30). The bolster (56) and the second lateral beam (22) are flexibly supported by a second connection portion (52B) disposed on the left side of the core receiver (30). Thus, it is possible to suppress variations in lateral pressure and wheel load in a curved path.
