Abstract
The present invention relates to rail vehicle side wall upper side beam structure, including：Cross section is in the strip roof side rail of shape for hat opening inwardly, the inside interval of roof side rail is welded with stiffener plate, stiffener plate has three supporting surfaces, it is respectively held against roof side rail back inner side, roof side rail upper end and roof side rail lower end, the upper end at roof side rail back is suppressed with the portion of caving in, for being overlapped with the extension edge of carline lower end, the side of carline and the side of side wall column are alignd with the stiffener plate, and enclosed ring is formed with reference to body transom.Roof side rail of the present invention enables framed side wallboard and roof panels rounding off in side wall and roof interface pressure locust leg, meet speed car requirement outside plate it is smooth, it is streamlined it is good, resistance is small etc. requires.In addition, the reinforcement in roof side rail aligns with carline and side wall column, enclosed ring is formed with reference to body transom, further improves the strength and stiffness of whole car body.
Description
Technical field
The present invention relates to rail vehicle side wall upper side beam structure, belongs to vehicle body of railway vehicle long strands field.
Background technology
With the high speed development of Railway Market, the continuous improvement of the speed of service, the strength and stiffness in car body are focused more on,
The single order curved mode of hanging down for especially improving car body is particularly important.And at present the conventional passenger vehicles side wall cantrail rigidity of structure compared with
It is weak, it is unfavorable for improving the rigidity of side wall and whole car body, this just needs to design a kind of roof side rail of brand-new section to meet car body
Strength and stiffness requirement.The interface relationship with other parts is also taken into full account in addition so that welding procedure is easy to operate, postwelding
It is elegant in appearance.
The content of the invention
The technical problems to be solved by the invention are to overcome the disadvantages mentioned above of prior art, there is provided a kind of rail vehicle side
Wall upper side beam structure, by traditional scattered package assembly modularization, car end bottom is easily installed in, is allowed to other structures and equipment
Go out installing space.
In order to solve the above technical problems, rail vehicle side wall upper side beam structure provided by the invention, it is characterised in that bag
Include：Cross section is in the strip roof side rail of shape for hat opening inwardly, and mouth is fixed under the upper end of roof side rail and carline, roof side rail
Lower end and the fixation suitable for reading of side wall column, the inside interval of the roof side rail is welded with stiffener plate, the stiffener plate
With three supporting surfaces, roof side rail back inner side, roof side rail upper end and roof side rail lower end are respectively held against, the roof side rail back
Upper end is suppressed with the portion of caving in, for being overlapped with the extension edge of carline lower end, the side of carline and side wall column
Side alignd with the stiffener plate, with reference to body transom formed enclosed ring.
The present invention also has following improve：
1st, perforate in the middle part of the stiffener plate.
2nd, the roof side rail back and the connecting position of roof side rail upper end and the phase at roof side rail back and roof side rail lower end
Connecing position has arcuate structure.
3rd, the roof side rail roll bending formation.
Roof side rail of the present invention enables framed side wallboard and roof panels rounding off in side wall and roof interface pressure locust leg,
Meet speed car requirement outside plate it is smooth, it is streamlined it is good, resistance is small etc. requires.In addition, reinforcement and carline in roof side rail
Alignd with side wall column, form enclosed ring with reference to body transom, further improve the strength and stiffness of whole car body.
Brief description of the drawings
The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is rail vehicle side wall upper side beam structure schematic diagram.
Label is schematically as follows in figure：
1- carlines；2- roof side rails；3- stiffener plates；4- side wall columns；5- caves in portion；6- holes.
Embodiment
As shown in figure 1, the present embodiment rail vehicle side wall upper side beam structure, including：The cross section of roll bending formation is in shape for hat
The strip roof side rail 2 of opening inwardly, 1 time mouth of upper end and carline of roof side rail 2 are fixed, the lower end of roof side rail 2 and side wall
4 fixation suitable for reading of column, the inside interval of roof side rail 2 are welded with stiffener plate 3, the middle part perforate 6 of stiffener plate 3, strengthened
Gusset 3 has three supporting surfaces, is respectively held against the back of roof side rail 2 inner side, the upper end of roof side rail 2 and the lower end of roof side rail 2, roof side rail 2
Back has arc knot with the connecting position of the upper end of roof side rail 2 and the connecting position at the back of roof side rail 2 and the lower end of roof side rail 2
Structure；The upper end at the back of roof side rail 2 is suppressed with the portion of caving in 5, and for being overlapped with the extension edge of the lower end of carline 1, roof is curved
The side of beam 1 and the side of side wall column 4 are alignd with stiffener plate 3, and enclosed ring is formed with reference to body transom.
In the present embodiment, roof side rail uses large scale section entirety roll bending formation, the module of anti-bending section of whole roof side rail
It is larger, the strength and stiffness of side wall or even whole car body are improved, the single order for being improved particularly car body hangs down curved modal frequency；Pass through
The stiffener plate of the inside, stiffener plate are alignd with carline and side wall column, are formed enclosed ring with reference to body transom, are entered
One step improves the intensity and rigidity of car body；Roof side rail inwardly, can realize the spot-welding technology with outside plate using opening；Roll bending suitable for reading
Into locust leg so that framed side wallboard and roof panels can smooth transition, it is elegant in appearance, it is streamlined good, reduce resistance.
In addition to the implementation, the present invention can also have other embodiment.It is all to use equivalent substitution or equivalent transformation shape
Into technical scheme, all fall within the protection domains of application claims.
