Problems solved by technology

[0010] At the same time, most of the connection between the beam and the side beam is that the beam is directly inserted into the side beam, resulting in a huge load stress on the side beam, which will easily caus

Example Embodiment

[0038] 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 with reference to the accompanying drawings and specific embodiments.

[0039] In an embodiment of this application, such as image 3 , 4 Shown in image 3 A three-dimensional schematic diagram of the side beam 10 is shown in Figure 4 A schematic diagram of the three-dimensional structure of the side beam 10 from another angle is shown in. A side beam 10 in the present application. The upper part of the side beam 10 is used to carry an air spring 8. A backing plate 9 is fixed between the side beam 10 and the air spring 8, and the upper surface of the backing plate 9 is made by cutting. The backing plate 9 is preferably circular, but should not be limited to this shape. The addition of the backing plate 9 has the following positive effects: the backing plate 9 is added between the air spring 8 on ...

Abstract

The invention provides a frame comprising two side beams and two crossbeams arranged between the two side beams. Each crossbeam is connected with the side portion of the corresponding side beam, the crossbeams and the side beams are connected through crossbeam connecting seats, and the crossbeam connecting seats are located at a large stress area at the junctions of the side beams and the crossbeams. The design aims to improve connecting structures between the crossbeams and the side beams, the large stress area is arranged on a transition seat, the transition seat is a forge piece, and the forge piece has better mechanical performance than a welding piece. On this basis, the invention further provides a railway train with the side beams.

Description

technical field [0001] The invention relates to the technical field of rail vehicle bogie structures, in particular to a frame and a rail train with the frame. Background technique [0002] The bogie is divided into a power bogie and a trailer bogie. It is one of the most important components in a rail vehicle system. Whether its structural design is reasonable will directly affect the running quality, power performance and safety performance of the vehicle. [0003] Therefore, the bogie we designed must meet the following requirements: [0004] Bearing: bear the weight of each part above the bogie; [0005] Guidance: to ensure that the vehicle runs safely on the track; [0006] Cushioning: ease the impact of uneven lines on the vehicle and ensure that the vehicle has good running stability: [0007] Traction (power bogie): ensure the necessary track adhesion, and transfer the traction force of the wheel circle generated at the contact point of the track to the car body; ...
