Problems solved by technology

However, in such a design, there are too many connecting parts between the railway freight car bogie and the car body, such as traction devices, secondary springs, transverse shock absorbers, anti-snaking shock absorbers, etc., and the connection between the car body and the bogie The space is limited, which brings difficulties to the assembly and disassembly of the bogie and car body

Embodiment Construction

[0033] The core of the present invention is to provide a railway freight car bogie and its corbel. The corbel structure can reduce the connection points between the railway freight car bogie and the car body, and reduce the difficulty of assembly and disassembly.

[0034] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For ease of understanding and concise description, the following description will be made in conjunction with the railway freight car bogie and its corbel, and the beneficial effects will not be discussed repeatedly.

[0035] It should be noted that the orientation words such as horizontal and vertical in this article are defined based on the angle of view when the bogie is assembled on the railway wagon when it is running normally; it should be understood that the use of th...

Abstract

The invention discloses a wagon bogie and a sleeper beam thereof. The sleeper beam comprises a beam body. The two ends of the beam body are provided with protruding portions respectively, wherein the protruding portions are symmetrical about a transverse center line. The protruding portions are provided with installation holes connected with a wagon body and anti-snaking damper bases are arranged on the two protruding portions located on one side of the transverse center line. The two ends of the beam body are further provided with secondary spring bases symmetrical about a lengthwise center line. Wing plates symmetrical about the transverse center line are arranged in the middle of the beam body and installation holes for installing traction pins are formed in the wing plates. The sleeper beam structure can be connected with a traction system of the bogie, anti-snaking dampers of the bogie and secondary springs of the bogie, connection between the sleeper beam and the wagon body is easy to realize, therefore, through the sleeper beam structure, connecting points between the bogie and the wagon body can be reduced and the assembling difficulty and the splitting difficulty between the bogie and the wagon body can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of rail vehicle bogies, in particular to a corbel of a railway freight car bogie. The present invention also relates to a railway freight car bogie with the above corbel. Background technique [0002] As my country's requirements for the quality and timeliness of material transportation are getting higher and higher, railway freight cars with a running speed of more than 200km / h will be one of the main directions for the development of railway freight cars in my country in the future. [0003] At present, for railway freight cars with a running speed of more than 200km / h, the connection structure without bolsters is mostly used between the bogie and the car body. However, in such a design, there are too many connecting parts between the railway freight car bogie and the car body, such as traction devices, secondary springs, transverse shock absorbers, anti-snaking shock absorbers, etc., and the connection b...
