Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.
Embodiment:
With reference to figure 1, the present invention includes central sill composition 1, sleeper beam composition 2, crossbeam 3, floor 4, longitudinal beam 5,6 and end carriage 7.
With reference to figure 1, Fig. 2, in truck underframe of the present invention, described central sill composition 1 is steel plate installed-welded formula box-structure, forms primarily of integral type striker 11, lower cover composition 12, integral type center filler 13, upper cover plate composition 14, web assembly 15 assembly welding.The draw beam part of coupler and draft gear need be installed in central sill two ends, and its inner width is the 350mm of standard, and centre portion box beam width is comparatively large, can increase central sill module of anti-bending section; Further, web assembly 15 forms according to the steel plate splicing of uniform strength design principle by three sections of different-thickness, and two end webs are thicker bears longitudinal direction of car tensile load, and it is thinner that interlude bears vertical load part thickness of slab; Further, arc transition plate 16,17 is designed in the upper and lower cover plate of central sill and crossbeam, sleeper beam junction, changes attachment weld position, can reduce stress and concentrate the weld cracking caused.
With reference to figure 1, Fig. 3 ~ Fig. 6, in truck underframe of the present invention, described sleeper beam composition 2 adopts two-way variable cross-section box type structure, and spacing is larger between central sill junction two body bolster diaphragm 21, between two body bolster diaphragms of outside, spacing is less, underframe centre portion load can be more transmitted to underframe both sides by this structure, the load that underframe is born evenly, structure stress is more reasonable; Described floor 4 is spliced by straight section floor 41 and two sections of arc floor boards 42, wherein arc floor board 42 is provided with many places arc notch, indentation, there installing floor board mends plate 43, floor is mended plate 43 and is overlapped on bottom, floor 42, this structure conveniently can clean compartment inner product goods, good drainage can be played again, reduce floor compartment rate of corrosion.
