Second end, end underframe 200 include sleeper beam 230, draw beam 220 and pillow interior beam 240, also, sleeper beam 230,220 and of draw beam
Pillow interior beam 240 set gradually along the direction of first end to the second end of end underframe 200, and draw beam 220, sleeper beam 230 with
And the intensity of pillow interior beam 240 successively successively decreases and is transferred to the first side bar 270 with the tractive force that will act on draw beam 220.
The Undercarriage structure makes that three's is strong by arranging draw beam 220, sleeper beam 230 and pillow interior beam 240 step by step
Degree, rigidity are successively successively decreased, so that longitudinal traction is uniformly distributed, are realized the integrated carrying of car body, are met the chassis of train
The intensity of structure all directions needs, while can mitigate Undercarriage structure own wt, so save production, in operation at
This.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
