Therefore, the traction beam structure can be applied to different coupling types of couplers, and the transition and change of new and old vehicle types can be realized.

[0037] Next, the traction beam structure is described in detail in combination with the drawings.

[0038] As shown in Figure 1 , the end beam module 1 is fixed at one end of the traction beam module 2, and in the embodiment, the two are welded and fixed to form a stable whole.

[0039] As shown in Figure 2 and Figure 3 , the end beam module 1 includes a coupler mounting plate, a buffer plate 103, an end beam upper cover plate, an end beam lower cover plate 104 and the like, wherein the coupler mounting plate has an opening at the middle position, the opening is butted with the interface formed by the traction beam module 2; one buffer plate 103 is connected at each end of the coupler mounting plate, and the buffer plate 103 is fixed with the vehicle body.

[0040] In the embodiment, the direction of the head of the railway wagon is defined as the front direction, the installation side of the buffer plate 103 is the front side, and the other side is the back side (back side). The end beam upper cover plate and the end beam lower cover plate 104 are parallel to each other and are arranged at the back side of the coupler mounting plate; the end beam upper cover plate is fixed with the buffer plate 103 and the top of the coupler mounting plate, and the end beam lower cover plate 104 is fixed at the bottom of the buffer plate 103 and the coupler mounting plate.

[0041] The coupler mounting plate forms a concave structure relative to the buffer plate 103, which facilitates cooperation with the traction beam module 2.

[0042] In order to increase the structural strength of the end beam module 1, a reinforcing unit is connected between the end beam upper cover plate and the end beam lower cover plate 104, and the reinforcing unit is symmetrically arranged relative to the coupler mounting plate.
