Abstract
The invention relates to a side wall upper boundary beam structure of a railway vehicle. The side wall upper boundary beam structure of the railway vehicle comprises a long-strip-shaped upper boundary beam with a cap-shaped cross section and an inward opening. Reinforcing rib plates are fixedly welded into the upper boundary beam at intervals. Each reinforcing rib plate is provided with three supporting faces which abut against the inner side of the back of the upper boundary beam, the upper end of the upper boundary beam and the lower end of the upper boundary beam respectively. An inwards-sunken part is pressed to the upper end of the back of the upper boundary beam and used for being in lap joint with the extending edge of the lower end of a roof bent beam. The side face of the roof bent beam and the side faces of side wall stand columns are aligned with the reinforcing rib plates, and a closed ring structure is formed through combination with a bottom frame cross beam. The upper boundary beam is pressed by grasshopper leg parts on connectors of side walls and a roof so that side wall plates and a roof plate can be in smooth transition, and the requirements of a high-speed vehicle for a flat outer plate, a good streamline, small resistance and the like are met. Besides, reinforcing ribs in the upper boundary beam are aligned with the roof bent beam and the side wall stand columns, and the closed ring structure is formed through combination with the bottom frame cross beam. The strength and the rigidity of a whole vehicle body are further improved.
Description
Technical field
The present invention relates to rail vehicle side wall upper side beam structure, belong to vehicle body of railway vehicle long strands field.
Background technology
Along with the high speed development of Railway Market, improving constantly of running velocity, pays close attention to the strength and stiffness of car body more, and the single order especially improving car body curved mode of hanging down seems particularly important.And the conventional passenger vehicles side wall cantrail rigidity of structure is more weak at present, be unfavorable for the rigidity improving side wall and whole car body, this just needs the roof rail designing a kind of brand-new section to meet car body strength and rigidity requirement.Also will take into full account the interface relationship with other parts in addition, make welding process easy to operate, postwelding is elegant in appearance.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the above-mentioned shortcoming of prior art, provides a kind of rail vehicle side wall upper side beam structure, by traditional loose package assembly modularization, is easily installed in car bottom portion, abdicates installing space to other structures and equipment.
In order to solve above technical matters, rail vehicle side wall upper side beam structure provided by the invention, it is characterized in that comprising: cross-sectional plane is shape for hat opening strip shape roof rail inwardly, upper end and the carline end opening of roof rail are fixed, the lower end of the upper end of roof rail and side wall column suitable for reading fixing, the internal interval of described roof rail be welded with reinforcement gusset, described reinforcement gusset has three bearing surfaces, prop up inside roof rail back respectively, roof rail upper end and roof rail lower end, the upper end at described roof rail back is suppressed with the portion of caving in, for overlapping with the extension edge of carline lower end, align with described reinforcement gusset in the side of carline and the side of side wall column, enclosed ring is formed in conjunction with body transom.
The present invention also has following improvement:
1, perforate in the middle part of described reinforcement gusset.
2, the connecting position of described roof rail back and roof rail upper end and the connecting position of roof rail back and roof rail lower end have arcuate structure.
3, described roof rail roll bending formation.
Roof rail of the present invention presses locust leg to make framed side wallboard and roof hoard can rounding off at side wall and roof interface, meets the requirements such as speed car requirement outside plate is smooth, stream line pattern good, resistance is little.In addition, the reinforced rib in roof rail aligns with carline and side wall column, forms enclosed ring in conjunction with body transom, improves the strength and stiffness of whole car body further.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is rail vehicle side wall upper side beam structure schematic diagram.
Number in the figure is schematically as follows:
1-carline; 2-roof rail; 3-strengthens gusset; 4-side wall column; 5-caves in portion; 6-hole.
Detailed description of the invention
As shown in Figure 1, the present embodiment rail vehicle side wall upper side beam structure, comprise: the cross-sectional plane of roll bending formation is shape for hat opening strip shape roof rail 2 inwardly, upper end and carline 1 end opening of roof rail 2 are fixed, the lower end of the upper end of roof rail 2 and side wall column 4 suitable for reading fixing, being welded with of internal interval of roof rail 2 strengthens gusset 3, strengthen perforate 6 in the middle part of gusset 3, strengthen gusset 3 and there are three bearing surfaces, prop up inside roof rail 2 back respectively, roof rail 2 upper end and roof rail 2 lower end, the connecting position of roof rail 2 back and roof rail 2 upper end, and the connecting position of roof rail 2 back and roof rail 2 lower end has arcuate structure, the upper end at roof rail 2 back is suppressed with the portion of caving in 5, and for overlapping with the extension edge of carline 1 lower end, aliging with reinforcement gusset 3 in the side of carline 1 and the side of side wall column 4, forms enclosed ring in conjunction with body transom.
In the present embodiment, roof rail adopts the overall roll bending formation of large scale section, and the module of anti-bending section of whole roof rail is comparatively large, improves the strength and stiffness of side wall and even whole car body, and the single order that especially improve car body hangs down curved model frequency; By the reinforcement gusset of the inside, strengthen gusset and align with carline and side wall column, form enclosed ring in conjunction with body transom, improve the strength and stiffness of car body further; Roof rail adopts opening inwardly, can realize the spot-welding technology with outside plate; Roll bending suitable for reading becomes locust leg, makes framed side wallboard and roof hoard can smooth transition, and elegant in appearance, stream line pattern is good, reduces resistance.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of application claims.
