Radial low-center-plate bogie for railway wagon and railway wagon

Abstract

The radial low-center-plate bogie comprises a bottom frame, a lower center plate is arranged in the middle of the bottom frame, the two ends of the bottom frame are installed on two suspension dampingdevices respectively, each suspension damping device is provided with a downwards-concave U-shaped structure, and the bottom frame is elastically borne in the U-shaped structures. The suspension damping device comprises a first side frame and a second side frame which are fixed in an inserted mode, a first wheel shaft is connected between the first side frames of the two suspension damping devices through a first bearing saddle, a second wheel shaft is connected between the second side frames through a second bearing saddle, and a third wheel shaft is installed at the inserted position of thefirst side frames and the second side frames through a third bearing saddle. And a first connecting rod and a second connecting rod which are distributed in an X shape are arranged between the firstbearing saddle and the second bearing saddle. The bogie meets the requirement of a low bearing surface of a rail wagon.

Description

technical field [0001] The invention relates to the technical field of railway freight cars, in particular to a radial low-center bogie for railway freight cars and a railway freight car. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Increasing the effective volume of the vehicle and reducing the invalid space has always been a development direction of railway freight cars. The emergence of low-floor railway freight cars suitable for humpback transportation is a new solution to improve the effective loading space of vehicles: this low-floor railway freight car It is required that the height of the bogie center plate is lower and the weight of the bogie is lighter. The inventors have found that most of the existing railway freight car bogies use φ840mm wheels, which makes it difficult to reduce the height of the center disc surface from the rail ...

AI Technical Summary

Problems solved by technology

The inventors have found that most of the existing railway freight car bogies use φ840mm wheels, which makes it difficult to reduce the height of the center disc surface from the rail surface, and also makes the mounting surface of the vehicle and the bogie joint higher, which affects the reduction of the railway freight car bearing surface. The continuous transport function has adversely affected the
