The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 4 is the cross-sectional configuration schematic diagram of needle beam for the rolling stock of the utility model one embodiment.As shown in Figure 4, the rolling stock of the utility model one embodiment comprises two connected side plates 11 and the base plate 12 between described side plate 11 with needle beam 1, and described side plate 11 and described base plate 12 are one-body molded, and the transversal surface of described needle beam 1 is A font.
Therein in a kind of embodiment, the thickness of two side plates 11 and base plate 12 can be 6mm, the height of base plate 12 can be 1/3 of the height of needle beam 1, the rolling stock of this structure is good with needle beam 1 support performance, it not only can adapt to the riveted joint with other assembly, and can alleviate deadweight, can relatively increase in addition load-carrying and the volume of car body.
In other embodiments, can suitably regulate the thickness of described side plate 11 and described base plate 12 and the height of described base plate 12 according to actual conditions such as car body load-carrying requirements, and the thickness of described side plate 11 can regulate in the scope of 4～10mm, the thickness of described base plate 12 can regulate in the scope of 4～10mm, and the thickness of described base plate 12 can be identical or different with side plate 11; The height of described base plate 12 can regulate in 1/3～1/4 scope of needle beam height.For example, when car body load-carrying is relatively large, can suitably the thickness of side plate 11 and base plate 12 be increased to 10mm; And when car body load-carrying reduces relatively, can suitably the thickness of side plate 11 and base plate 12 be decreased to 4mm.
