Problems solved by technology

[0004] With the development of social economy, some cargo transportation needs better dynamic performance and escort personnel. The stability of the side frame of the traditional truck bogie is poor, and the stability index is low, which cannot meet the requirements of cargo transportation and long-term operation of personnel.

Embodiment Construction

[0025] The implementation of the present invention will be described in detail below in conjunction with the examples of implementation, but they do not constitute a limitation of the present invention, and are only examples. At the same time, the advantages of the present invention will become clearer and easier to understand.

[0026] Such as figure 1 The shown bogie side frame of a high dynamic performance railway freight car includes a side frame body 1, the middle part of the side frame body 1 has a first opening structure 1.1 facing upward, and the two ends of the side frame body 1 respectively have a second opening structure facing downward. The opening structure 1.2; the first opening structure 1.1 and the second opening structure 1.2 at both ends are integrally cast; the bogie side frame of the present invention has no upper chord. Side frame pedestals 2 are symmetrically arranged at both ends of one side of the side frame body 1, and the side frame pedestals 2 are u...

Abstract

The bogie side frame comprises a side frame body, the middle of the side frame body is provided with a first opening structure facing upwards, and the two ends of the side frame body are each provided with a second opening structure facing downwards; the first opening structure and the second opening structures at the two ends are integrally cast and formed. Side frame guide frames are symmetrically arranged at the two ends of the side face of one side of the side frame body and used for installing rubber springs of railway wagon axle boxes. A traction pull rod mounting seat is arranged above one of the side frame guide frames; the traction rod mounting seat is perpendicular to the side wall of the side frame body, and the traction rod mounting seat and the side frame body are integrally cast and formed and are used for mounting a longitudinal traction rod to transmit longitudinal force to the side frame body. The side frame of the bogie of the high-dynamic-performance railway wagon is integrally cast, the structural strength is reliable, an upper chord and a stand column wearing plate are omitted, a traction rod mounting seat is mounted, and the dynamic performance of the bogie is improved.

Description

technical field [0001] The invention relates to the technical field of bogies, in particular to a bogie side frame and a bogie of a railway freight car with high dynamic performance. Background technique [0002] Freight car bogies generally adopt three-piece bogies, which are mainly composed of side frames, bolsters, wheelsets, wedge damping devices, foundation brake devices, anti-water chestnut devices, and side bearings. The structure is simple, and the manufacturing and maintenance costs are low. Inexpensive, dynamic performance can meet the needs of cargo transportation. [0003] The side frame is an important load-bearing part of the railway freight car bogie. It is not only related to the performance of the bogie, but also related to the safety of railway transportation. In the past 20 years, the design and manufacturing technology of my country's side frame has been greatly improved, and the product quality has also been continuously improved. The main functions o...
