Problems solved by technology

[0002] Vehicle weight reduction is an effective way to save energy consumption in operation. At present, under the premise of ensuring the safety performance of vehicles, it is difficult to reduce the weight of steel frame side beams through structural optimization. At this time, the replacement of materials is one of the breakthroughs in this technical bottleneck. It is an effective means, but only material replacement is obviously unable to meet the driving requirements of the vehicle

Embodiment Construction

[0029] 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.

[0030] Please refer to Figure 1-3 , figure 1 It is a structural schematic diagram of the side beam 1 of the bogie provided by the embodiment of the present invention; figure 2 for figure 1 top view of image 3 for figure 1 A schematic diagram of another viewing angle of the middle side beam 1 , showing the bottom of the side beam 1 .

[0031] The side beam 1 of the bogie in this embodiment is a hollow box-shaped beam structure, including a middle beam body 11 and an end beam body 12 positioned at both ends of the middle beam body 11, and the middle beam body 11 and the end beam body 12 are One-piece structure, such as figure 1 As shown, the side beam 1 is a box-shaped beam structure. Among them, the middle beam b...

Abstract

The invention discloses a side beam of a bogie, the bogie, a rail vehicle and a forming process of the side beam. The side beam comprises a middle beam body and end beam bodies located at the two ends of the middle beam body, the middle beam body is used for being connected with a cross beam of the bogie, and the middle beam body and the end beam bodies are integrally made of fiber composite materials. The inner side of the middle beam body protrudes inwards relative to the inner sides of the adjacent end beam bodies to form a first-stage step part, the middle of the inner side of the middle beam body protrudes outwards relative to the first-stage step part to form a second-stage step part, and the first-stage step part corresponds to the position connected with a cross beam. the top of the two-stage step part is used for supporting an air spring which is eccentrically arranged. According to the scheme, the inner side of the side beam is provided with two steps, the thickness of the corresponding position of the side beam is increased through the first-stage step part so as to enhance the strength of the connecting position of the side beam and the cross beam, and the second-stage step part further protrudes inwards so as to provide enough supporting area to assist in supporting the air spring which is eccentrically arranged.

Description

technical field [0001] The invention relates to the technical field of bogies, in particular to a side beam of a bogie, a bogie, a rail vehicle and a forming process of the side beam. Background technique [0002] Vehicle weight reduction is an effective way to save energy consumption in operation. At present, under the premise of ensuring the safety performance of vehicles, it is difficult to reduce the weight of steel frame side beams through structural optimization. At this time, the replacement of materials is one of the breakthroughs in this technical bottleneck. It is an effective means, but only material replacement is obviously unable to meet the driving requirements of the vehicle. Contents of the invention [0003] The invention provides a side beam of a bogie. The side beam includes a middle beam body and end beam bodies located at both ends of the middle beam body. The middle beam body is used to connect the cross beam of the bogie. The middle beam The body an...
