Bolster of express railway freight car bogie

Abstract

The invention discloses a bolster of a high-speed railway freight car bogie. The bolster comprises a bolter upper cover plate, bolster web plates, a bolster lower cover plate and bolster end plates. The bottoms of the two bolster web plates are symmetrically arranged on the bolster lower cover plate. The bolster upper cover plate is arranged at the upper parts of the two bolster web plates. A spherical hole is arranged at the middle part of the bolster upper cover plate. The bolster upper cover plate is connected with a spherical center plate. The spherical hole is matched with the external spherical surface of the spherical center plate. Side bearing installation seats are arranged on the two sides of the upper end surface of the bolster upper cover plate. Transverse elastic bolster guides are arranged on the side bearing installation seats. The bolster upper cover plate is connected with the bolster end plates. Bolster lower hanger rod seats are arranged on the bolster end plates. Longitudinal bolster guide wearing plates are arranged on the bolster web plates. The bolster of the express railway freight car bogie has the advantages of simple structure and reliable performance, is suitable for a bogie structure which adopts a hanger rod method, can effectively transmit all-direction loads coming from a car body to the frame of the bogie and can satisfy the structural requirement on the swing bolster of the 160km / h high-speed railway freight car bogie.

Description

technical field [0001] The invention relates to a bolster of a railway freight car bogie, in particular to a bolster of a fast railway freight car bogie whose speed can reach 160 kilometers per hour. Background technique [0002] Railway vehicle bogies mainly include three-piece bogies and frame bogies. Among them, the three-piece bogie has obvious disadvantages such as small anti-diamond stiffness, large unsprung mass, and the inability to install disc brakes. Due to the advantages of small unsprung mass, the dynamic performance of the frame bogie is obviously better than that of the three-piece bogie. The bolster of the traditional fast freight car bogie is seated on the frame through the secondary spring, and the bolster adopts a flat surface. Center plate, which cannot accommodate the bogie structure of the boom system and the structural requirements of arranging the traction tie rod arrangement as the underside of the frame.
