Embodiment

[0021] refer to figure 1 , The present invention includes a center beam composition 1, a corbel composition 2, a beam 3, a floor 4, longitudinal beams 5, 6 and an end beam 7.

[0022] refer to figure 1 , figure 2 , in the railway gondola underframe of the present invention, the middle beam composition 1 is a steel plate welded box structure, mainly composed of an integrated impact seat 11, a lower cover plate 12, an integrated center plate seat 13, and an upper cover plate 14 , The web assembly is welded by 15 groups. Both ends of the center beam need to be installed with the traction beam part of the coupler buffer device, the inner width of which is the standard 350mm, and the width of the box beam in the middle part is larger, which can increase the bending section modulus of the center beam; further, the web assembly 15 is based on the equal strength The design principle is composed of three sections of steel plates with different thicknesses. The thicker webs at both ...

Abstract

The invention belongs to novel technologies of railway trucks and relates to a railway truck chassis. The railway truck chassis comprises a middle beam assembly, a longitudinal beam assembly parallel to the middle beam assembly, a sleeper beam assembly perpendicularly fixed to the middle beam assembly, cross beams perpendicularly fixed to the middle cross beam assembly, end beams arranged at the two ends of the middle beam assembly and a floor laid on the middle beam assembly. The floor is formed by splicing two arcs and a straight plate. The floor has the function of a groove type lower side beam of a traditional railway truck. The end of an upper cover plate of each cross beam is arc and is welded to the arc floor. By the adoption of the railway truck chassis, according to the stress conditions, the sectional size is reasonably selected, the railway truck chassis is designed according to the principle of constant structural strength, the structure is simple, the dead weight is light, the appearance is novel, the connection mode of the components is reliable, the cross beams with arcs and the arc floor form a hidden lower side beam of the chassis, the deed weight of a truck is reduced, the complete discharging rate of goods is increased, and the visual effect of the integrated appearance is improved.

Description

technical field [0001] The invention belongs to the new technology of railway wagons, and relates to an underframe of a railway open car. Background technique [0002] The existing railway gondola underframe is generally composed of middle beams, side beams, corbel beams, large and small beams and floors. connected by beams. This kind of structural underframe generally cannot optimize the section size according to the actual stress situation, and it is difficult to achieve equal strength design. Therefore, its own weight is generally large, and it cannot meet the current development requirements of my country's railway freight vehicles for weight and light weight. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art; it provides an invisible underframe with simple structure, light weight, novel appearance, reliable connection of each part, and arc-shaped beam and arc-shaped floor structure. The side beam ...
