The draft sill 100 comprises two draft sill webs 1 which are arranged oppositely at intervals, and a coupler mounting seat 200 is arranged between the two draft sill webs 1 and used for meeting the mounting requirements of a coupler.
Wherein, the upside of each draft sill web 1 is connected with turn-ups 11 respectively, and two turn-ups 11 back on the back set up. The lower side of each traction beam web plate 1 is respectively connected with a lower flanging 12, and the two lower flanging 12 are arranged back to back. The outer side of each traction beam web plate 1 is respectively provided with a first reinforcing plate 13, the first reinforcing plates 13 are arranged in parallel with the traction beam web plate 1, and the first reinforcing plates 13 are connected between an upper flange 11 and a lower flange 12, so that the traction beam web plate 1, the upper flange 11, the first reinforcing plates 13 and the lower flange 12 can be enclosed to form a bearing cavity 14, and the bearing cavity is used as a main bearing structure of the traction beam, and the structural strength of the traction beam is effectively improved.
Wherein, a bumper beam interface 15 is formed among the first end of the draft sill web 1, the first end of the upper flange 11, the first end of the first reinforcing plate 13 and the first end of the lower flange 12, and the draft sill 100 is connected with the bumper beam 300 through the bumper beam interface 15.

As shown in fig. 12 and 13, in some embodiments of the invention, the connector 3 includes a cuff connector 31, a web connector 32, and a bolster connector 33. The flange connecting portion 31 includes a first connecting plate 311, a second connecting plate 312, a third connecting plate 313 and a fourth connecting plate 314, which are sequentially connected from left to right, and the first connecting plate 311 is connected to the second end of the upper flange 11, so that the connection and fixation between the connecting member 3 and the upper flange 11 are realized. The upper side of the first reinforcing plate 13 is connected to the lower surface of the one side of the flange connecting portion 31 extending in the longitudinal direction, so that the connection and fixation between the connecting member 3 and the first reinforcing plate 13 are achieved.
Wherein, web connecting portion 32 is the connecting plate to the setting vertically, and web connecting portion 32 sets up in the opposite side that turn-ups connecting portion 31 extends along length direction to the upside of web connecting portion 32 links to each other with the lower surface of turn-ups connecting portion 31. The lower side of the web connecting part 32 is connected with the upper side of the towing beam web 1, so that the connecting piece 3 and the towing beam web 1 are fixedly connected.
Wherein the bolster connecting portion 33 is connected to the fourth connecting plate 314 of the burring connecting portion 31, and the upper side of the web connecting portion 32 is connected to the lower surface of the bolster connecting portion 33. The upper side of the first reinforcing plate 13 is connected to the lower surface of the bolster connecting portion 33, thereby achieving the connection fixation between the connecting member 3 and the first reinforcing plate 13. That is, the connecting member 3, the towing beam web 1, the lower flange 12 and the first reinforcing plate 13 can be enclosed to form the mounting chamber 4, which facilitates the stable and reliable mounting between the towing beam 100 and the sleeper beam 400.
Specifically, the width of the cuff connecting portion 31 is the same as the width of the upper cuff 11, and the width of the bolster connecting portion 33 is greater than the width of the cuff connecting portion 31, so that both ends of the bolster connecting portion 33 extending in the width direction can respectively extend to the outside of the mounting chamber 4, thereby facilitating stable and reliable mounting between the bolster connecting portion 33 and the bolster 400.
Specifically, one end of the web connecting portion 32, which is far away from the upper flange 11, is flush with the second end of the towing beam web 1, the second end of the first reinforcing plate 13 is flush with the second end of the towing beam web 1, and the second end of the lower flange 12 is flush with the second end of the towing beam web 1.

The setting position of the second horizontal plate 115 is higher than the setting positions of the second arc-shaped plate 114 and the third arc-shaped plate 116, the second arc-shaped plate 114, the inclined plate 113, the first arc-shaped plate 112 and the first horizontal plate 111 are sequentially arranged from top to bottom, and the third arc-shaped plate 116, the fourth arc-shaped plate 117 and the fifth arc-shaped plate 118 are sequentially arranged from top to bottom, so that the upper flange 11 is integrally of an upward convex structure. That is, the lower flange 12, the towing beam web 1 and the upper flange 11 can be in a protruding structure, so that the towing beam 100 is more compact in structure, and the occupied space of the towing beam 100 is further reduced.
The inclined plate 113 and the first horizontal plate 111 form an included angle of 120-135 degrees, so that the inclined plate 113 has a steeper gradient, the structure of the draft sill 100 is more compact, and the occupied space of the draft sill 100 is further reduced.
The sum of the projection lengths of the third arc-shaped plate 116, the fourth arc-shaped plate 117 and the fifth arc-shaped plate 118 on the lower flanging 12 is far greater than the sum of the projection lengths of the first horizontal plate 111, the first arc-shaped plate 112, the inclined plate 113 and the second arc-shaped plate 114 on the lower flanging 12, so that the extension of the upper flanging 11 to one end of the buffer beam interface 15 is shorter, and the extension of the upper flanging 11 to one end of the sleeper beam interface 16 is longer, so that the structure of the draft sill 100 is more compact, and the stable and reliable installation between the draft sill 100 and the buffer beam 300 and the sleeper beam 400 is conveniently realized.
In some embodiments of the present invention, the first reinforcing plate 13 includes a first connecting portion 131, a second connecting portion 132 and a third connecting portion 133 sequentially connected from left to right, a lower side of the first connecting portion 131 is connected to an upper surface of the lower flange 12, and an upper side of the first connecting portion 131 is spaced apart from the upper flange 11 such that an opening structure is formed between the first connecting portion 131 and the upper flange 11. The lower side of the second connecting portion 132 is connected to the upper surface of the lower flange 12, and the upper side of the second connecting portion 132 is connected to the lower surface of the fifth arc-shaped plate 118, so that the bearing chamber 14 can be formed by enclosing the second connecting portion 132, the lower flange 12, the towing beam web 1, and the upper flange 11. The lower side of the third connecting part 133 is connected with the upper surface of the lower flange 12, and the upper side of the third connecting part 133 is connected with the connecting part 3, so that the third connecting part 133, the connecting part 3, the towing beam web 1 and the lower flange 12 can be enclosed to form the mounting chamber 4.
