Problems solved by technology

However, for example, when the compression requirement is 3560kN, that is, when the actual compression condition of the car body is much greater than the compression condition required by the above-mentioned standard, the commonly used traction beam structure in the existing rail vehicles can no longer meet the requirements, resulting in the tendency of the traction beam to appear plate Failure conditions such as excessive stress and shear fracture of rivets

Embodiment 1

[0039] Please refer to figure 1 , figure 2 , image 3 and Figure 4 , the embodiment of the present application provides a traction beam 1, the traction beam 1 is used in rail vehicles to connect the coupler to the chassis of the car body, the traction beam 1 includes a bottom plate 11, a cover plate 12, a first vertical plate 13 , second vertical plate 14, coupler panel 15, horizontal support plate 16 and vertical support plate 17; Base plate 11, cover plate 12, first vertical plate 13, second vertical plate 14, coupler panel 15, horizontal support plate 16 and The vertical support plates 17 are all made of steel plates; wherein:

[0040] The cover plate 12 and the base plate 11 are vertically oppositely arranged; as image 3 and Figure 7 As shown in the structure, the cover plate 12 is arranged on the top of the draw beam 1, the base plate 11 is arranged on the bottom of the draw beam 1, and the cover plate 12 and the base plate 11 are arranged oppositely;

[0041] T...

Embodiment 2

[0059] The embodiment of the present application also provides a rail vehicle, and the rail vehicle includes any one of the traction beams 1 provided in the above embodiments.

[0060] The rail vehicle adopts the above-mentioned traction beam 1, and the structural strength and rigidity can be improved through the traction beam 1, thereby improving the compression resistance, so that the rail vehicle can ensure the reliability and safety of each car body when it receives a relatively high compression force , At the same time, it is also conducive to improving the reliability and safety of the connection between the various car bodies, thereby improving the reliability and safety of the entire rail vehicle.

Abstract

The present application relates to the technical field of rail vehicles, in particular, to a traction beam and a rail vehicle. The draw beam comprises a bottom plate, a cover plate, a first vertical plate, a second vertical plate, a coupler panel, a horizontal support plate and a vertical support plate; one side surface of the coupler panel is used for mounting the coupler, and the other side surface is used for The horizontal support plate, the coupler panel is welded to the base plate, the cover plate, the first vertical plate and the second vertical plate, and an installation space is formed on the side of the coupler panel where the coupler is installed, and a cavity is formed on the other side of the coupler panel away from the coupler body; the horizontal support plate is located in the cavity, and is welded with the coupler panel, the first vertical plate, and the second vertical plate; the vertical support plate is located in the cavity, and is welded with the cover plate, the first vertical plate, and the second vertical plate . The traction beam can enhance the anti-compression performance, and can make the car body meet the load-bearing requirements of the heavy compression working condition (for example, the compressing 3560kN working condition).

Description

technical field [0001] The present application relates to the technical field of rail vehicles, in particular, to a traction beam and a rail vehicle. Background technique [0002] The inspection standards for steel rail passenger cars commonly used in my country include the subway stainless steel car body standard BS EN12663-2 and the domestic carbon steel car body implementation standard TB / T 1335. Among them, the anti-compression index of the car body in the subway stainless steel car body standard is 800kN, while the anti-compression index for the car body in the domestic carbon steel car body implementation standard is 1180kN. However, for example, when the compression requirement is 3560kN, that is, when the actual compression condition of the car body is much greater than the compression condition required by the above-mentioned standard, the commonly used traction beam structure in the existing rail vehicles can no longer meet the requirements, resulting in the tendenc...
