Embodiment Construction

[0020] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] It should be noted that the terms "longitudinal", "transverse" and "vertical" appearing in the present invention refer to: when the bogie is parked on the railway track, it is "longitudinal" along the direction of the railway track; The direction of the bogie axle is "horizontal"; the direction perpendicular to the track plane of the railway line is "vertical". In the drawings of the present invention, figure 1 The left and right directions in are "portrait", figure 1 The up and down directions in are "vertical", image 3 The up and down directions in are "horizontal". And it should be understood that these terms are only used to illustrate specific embodiments of the present invention, and are not intended to l...

Abstract

The invention relates to a railway vehicle bogie which comprises an elastic middle intersecting supporting rod structure located between two side frames of the bogie, the side frames which are respectively provided with a narrow side frame pedestal opening, narrow bearing carrying saddles matched with the side frames and a series of elastic pads. The railway vehicle bogie can remarkably improve the rhombus-resistant performance of three-piece bogie of a wagon and the parallelogram (rhombus) phenomenon between the two side frames and two wheel pairs of the bogie is prevented, so that a curve negotiation performance of a vehicle is improved and the critical speed of snaking motion is increased. In addition, a small bogie rigid wheel base is selected by the railway vehicle bogie, the weight of the railway vehicle bogie is reduced, and the railway vehicle load is improved.

Description

technical field [0001] The invention relates to the technical field of railway transportation equipment, in particular to a three-piece bogie for railway freight cars. Background technique [0002] The bogie is one of the most important components in the structure of a railway vehicle. It is mainly used to increase the load, length and volume of the vehicle, increase the running speed of the train, and under the specified track conditions, it can ensure that no matter whether the vehicle is empty or heavy. When running at low speed or high speed, it has good running quality to protect vehicles and goods and meet the needs of railway transportation development. [0003] Among the existing three major bogies, some bogies are equipped with side frame elastic middle cross bracing structures and axle box elastic suspension devices, thereby improving the anti-diamond characteristics of the bogies. However, these bogies all adopt sideframes with wider axlebox pedestal openings in ...
