-via continuous laser welded seam, be bonded together by this way, each metal sheet forms the outside face without skew on the outside of push-and-pull regions module,

The metal sheet that-characteristic is different at least comprises the first metal sheet and the second metal sheet,

The-the second metal sheet correspondingly has resistivity, the particularly intensity larger than the first metal sheet and/or larger material thickness, and

The-the second metal sheet forms the region of the stress that appearance improves in the compartment of making by outer wall module in track vehicle operating of outer metal plate structure,

-wherein, the side wall surface forming by outer metal plate structure seals by top flange section bar at upper seamed edge, on the corresponding contiguous engagement that this top flange section bar is bonded on outer metal plate structure to ground connection metal sheet together distolateral, and in the region of laser welded seam, do not occur being on the outer surface offset, wherein top flange section bar comprises an outside face with respect to the side wall surface section bar section of the inside bend of modular walls outward, and

-the skeleton that formed by framework section bar,

-wherein, framework section bar is adjacent to the inner side of outer metal plate structure via T shape mating interface with distolateral docking seamed edge, and

-via laser welded seam, fix.

Not only the metal sheet of the planar extension of outer metal plate structure (they have almost constant material thickness transverse to planar extension respectively) is mutual, and outside forming the framework section bar on the metal sheet of metal plate structure respectively only via distolateral, be that those sides with as far as possible little contact surface interconnect.Therefore avoided material to double.Can obviously reduce generally thus the susceptibility-to-corrosion of outer wall outer wall module or that formed by one or more described modules of railway carriage.Top flange section bar inserts the end as horizontally extending upper seamed edge in outer wall module a plurality of advantages is provided.On the one hand, via docking by laser welding, engage and create a kind of unstressed and connection that warpage is little, this connection provides the outside face without skew.By arrange one towards inner face side wall surface or outer wall module the section bar section with respect to outer surface bending, also passable, in compartment, realize different cap members to realize different top shape minute section.The large alerting ability of top design is achieved.

A kind of method by suggestion obtains the outer wall module for railway carriage, the method comprises the following steps: will have different qualities, particularly the metal sheet of the planar structure of material thickness is bonded with each other into an outer metal plate structure that is configured to the push-and-pull regions module of self-supporting, wherein metal sheet is adjacent to each other and is bonded together by this way via continuous laser welded seam with its planar the distolateral of orientation of extending transverse to each metal sheet separately ground connection respectively, be that each metal sheet forms the outside face without skew on the outside of push-and-pull regions module, wherein said each metal sheet at least comprises that characteristic is different, different the first metal sheet and the second metal sheets of material thickness particularly, the second metal sheet correspondingly has the resistivity larger than the first metal sheet, particularly intensity and/or larger material thickness, the second metal sheet insert outer metal plate structure in track vehicle operating in the region of stress that occurs raising in outer wall module or the compartment made with outer wall, and manufacture skeleton by framework section bar, wherein framework section bar is adjacent to outer metal plate structure inner side and is fixed on outer metal plate structure via laser welded seam via T shape mating interface with distolateral docking seamed edge, the top flange section bar of wherein stipulating a bending joins on outer metal plate structure and the upper seamed edge of top flange section bar outer enclosed wall module and ground connection is bonded on the metal sheet of the adjacency at least the first and second metal sheets that material behavior is different by laser welding, and do not produce material on the outside face of side wall surface, do not suddenly change, wherein, top flange section bar comprises an outside face with respect to the side wall surface section bar section of the inner face bending of modular walls outward.

The invention provides such advantage, produce such outer wall construction, in the region of the stress loading that this outer wall construction occur to improve at those, there is enough resistivities or material thickness, other but occur also using resistivity or the less metal sheet of material thickness in the region of less stress loading.Create thus weight saving and/or in the situation that the outer wall that uses more economical material to make, but described outer wall is unaffected aspect its structural bearing capacity.Createed in process of production a kind of outer surface structure, this outer surface structure only needed slightly or not even to need additionally to process before applying outer paint.In addition avoided planar material to double, this material doubles otherwise has high liability for crevice corrosion.In addition, such structure allows the region of the stress that occurs improving to keep not having such seam.

Here the rolled products being made of metal is regarded as to the metal sheet of planar extension, these rolled products have substantially the same material thickness transverse to planar development length.Therefore metal sheet has at least local directed surface, plane parallel ground substantially each other.Perpendicular to or the side that forms transverse to these faces is called end face here and for each metal sheet is engaged with each other.Than engaging that metal sheet together and have in the chamfering edge region of the second metal sheet of larger material thickness, can be particularly favourable, so as in to complete the outer metal plate structure of joint optimization power stream.Here, the inner side of an outside metal plate structure in side of chamfering.

For obtain outer metal plate structure do not have as far as possible noisy outside face and in the meaning of the process technology of optimizing, the laser welded seam that the metal sheet of planar formation is engaged with each other is preferably from inner side outer metal plate structure or push-and-pull regions module structure.

The second metal sheet of outer metal plate structure is arranged on or forms like this in some regions, in these regions or on conformation function opening seamed edge, particularly function opening bight for example window bight and/or bight, doorway.

Owing to having to produce, do not there is the face that material doubles, for such outer wall module in compartment or such outer wall also can by otherwise the material with the high corrosion stability that is far from it manufacture.Therefore for example not necessarily, all metal sheets are made by corrosion-resistant steel that is high-alloy steel.But a kind of preferred embodiment in regulation, at least the first metal sheet, preferably additionally also have the metal sheet section bar of skeleton and most preferably additionally also have metal sheet section bar and second metal sheet of skeleton to be made by non-high-alloy steel.

The metal sheet of each planar extension that material thickness is different is preferably by exact method cutting.This preferably realizes via laser cutting method.Thus likely, manufacture like this each metal sheet, the seamed edge docking is each other engaged with each other best.Each metal sheet needn't be flat, but also can have protuberance or bending.

In order to set up being connected of the docking seamed edge of framework section bar and the optimization of outer metal plate structure, the docking seamed edge of section bar is cut into and makes them be matched with best the structure of the inner side of outer metal plate structure.This means, the docking seamed edge of framework section bar is cut into and makes to dock seamed edge and obtain and to have in other words grooving by laser cutting method, and described grooving adapts to the skew that the different material thickness of the upper metal sheet due to outer metal plate structure in metal plate structure inner side produces outside.In addition, docking seamed edge is also matched with the protuberance or the bending that exist if desired of outer metal plate structure certainly.Having created thus such possibility is connected via continuous laser welded seam, preferred I shape weld seam framework section bar with outer metal plate structure.Conventionally, welding is correspondingly implemented like this, i.e. this welding is not exclusively melted or penetrated outer metal plate structure.T shape mating interface also can be provided with a laser angular weld seam or two laser angular weld seams in another embodiment.

Framework section bar is engaged or is fixed on the inner side of the inner side of outer metal plate structure or the inner side of side wall surface or outer wall module and correspondingly always should be understood to, those places that framework section bar is also adjacent to top flange section bar at it are connected with this top flange section bar, that is to say, join on its inner side.Here engage like this and realize, framework section bar is correspondingly only connected with top flange section bar with distolateral being docked on the section bar of top flange and by laser welded material in locking manner.Because conventionally first top flange section bar is connected in locking manner with at least the first and/or second metallic sheet material, so the joint of the end face of framework section bar can be by the continuous weld configuration of bilateral if desired, these sides are docked on the one hand on the first and/or second metal sheet and are docked on the other hand on the section bar of top flange.The sealed connection of material is by laser welding structure, and not one of penetrating metal plate or top flange section bar.

Railway carriage comprises a sidewall made in accordance with the present invention, this sidewall is made by one or more outer wall modules, wherein sidewall-outer metal plate structure be configured to integratedly from carrying, with the push-and-pull regions module of integrated top flange section bar, a plurality of outer wall modules are engaged with each other by this way if desired, the metal sheet that is the outer metal plate structure of formation of different outer wall modules is bonded together via laser welded seam to ground connection with distolateral equally, thereby sidewall-outer metal plate structure is configured to not have the outside face of skew.

In some embodiments, first by a plurality of outer wall modules, produce by this way a side wall section, in the compartment of making of the outer wall module being adjacent to each other in this side wall section vertically or the lateral edges extending almost vertically ground connection is engaged with each other and forms the side wall section of a centre.The sidewall that can the modularization for compartment be extended is thus bonded together almost unstressedly.

In some embodiments, the other outer wall module being arranged on underframe end as sidewall end of like configurations is docked with middle side wall section and is connected by tolerance compensating.Outer metal plate structure just has one or two junction surface in these embodiments in each side in compartment, on described junction surface, implements tolerance compensating, so that the length of whole sidewall is matched with the length of prefabricated underframe.Form the outer wall module of sidewall end also referred to as outer wall end module.

In principle likely, this joint is implemented by the metal sheet of separately cutting, and these metal sheets form between the outer wall module of corresponding sidewall end and the side wall section of a centre and without being offset and insert by laser welding ground connection insertion.

The length that the length that has the junction of tolerance compensating so can make sidewall is matched with underframe is set in the outer wall module of formation sidewall end.In addition, the outer wall module that forms sidewall end generally includes a door otch, if be provided with a door in sidewall.The coupling of the Oil pipeline assembly of the door otch in modular walls and underframe can be in the situation that setting has the junction surface of tolerance compensating realizes equally relatively easily outside.

In order to need the car of lesser amt as far as possible generally in a length and occupant and/or stowage capacity car association predetermined, that formed by a plurality of cars joints, worth the wait, can produce long as far as possible car and so compartment.In order to realize this point and compensation compartment " curved falling to below theoretical zero position " between bogie truck, a kind of preferred embodiment in underframe along its longitudinal direction by salient manufacture and/or provide, and outer wall module manufactures trapezoidal, when thereby modular walls is bonded with each other into side wall section outside, this side wall section manufactures with the salient substantially matching with the salient of underframe or exceeds portion.Therefore the outer wall module of preferred standard manufactures with trapezoidal side.

For can be by top section or crown member arbitrarily, also have the different crown member of shape of cross section (for example flat or circular) with can being installed on the sidewall being formed by outer wall module by Variational-Type of the longitudinal direction along underframe or compartment, the side wall section outer wall module used in the middle of preferably at least forming all has same sidewall height.Here, outside the level under installing condition of modular walls or almost the distance between the seamed edge of horizontal orientation be counted as height.

If outer wall module is configured to, with trapezoidal side, produce the side wall section of a centre, the side wall section of this centre has polygonal section at lower seamed edge (with at upper seamed edge).This forms salient or exceeds portion.Because the rigidity of crown member reduces with respect to side wall member and particularly top flange section bar, so crown member is located bearing of trend along the longitudinal at an arbitrary position, be matched with salient or exceed portion.

The high stability of sidewall or outer wall module realizes by this way,, the side wall surface that is provided with top flange section bar is configured to from the push-and-pull region of carrying and to the inner side of the side wall surface of (outer metal plate structure) with top flange section bar, transverse to the continuous vertical framework section bar of the longitudinal extension direction orientation of the level of top flange section bar, as pillar, with it, distolaterally via T shape mating interface, by laser welding, is connected with the inner side of side wall surface.In the extra high compartment of stress, for example, for being in operation, there is the high speed train of aerodynamics reverse load, the preferred bilateral of T shape mating interface ground and being preferably fixed on the inner face of outer metal plate structure by laser welding continuously.Only by laser welding, can realize T shape mating interface, the seam cross-sectional plane of described T shape mating interface is not more than essential seam cross-sectional plane on calculating.As the framework section bar of whole vertical extension pillar, that cross over modular walls preferably with for leaving a blank of window, door or analogue, be adjacent to layout.

A kind of preferred embodiment in, on underframe and in crown member, engage or form framework section bar, described framework section bar when side wall section or outer wall module are bonded together with underframe and cap member and outer wall module or be correspondingly bonded into around the ring frame of constructing while engaging the pillar joint of the side wall section forming by outer wall module.Therefore in the compartment of making, form around ring frame, described ring frame is given the stability that compartment is high.

Preferably, using as the vertical framework section bar of pillar, be bonded on the inner face of side wall surface by laser welding as the framework section bar of the level of stringer and the framework section bar of the skeleton reinforcement as part of crossing over discontinuously the whole vertical extension of outer wall module.Here, each framework section bar engages via T shape mating interface with distolateral respectively.These framework section bars can preferably at least have the less system height perpendicular to outer metal plate structure inner face at region, the blind area vertical pillar of internal ratio, to create space for vent passages and/or air-conditioning passage.These framework section bars can have the breach for pipe laying.Pursue as far as possible little wall thickness with the long as far as possible configuration of car, to be that comfortable internal space design obtains structure space as much as possible in inside simultaneously.

In addition,, when side-wall metallic plate is formed from steel, realize the little system height perpendicular to the planar extension of sidewall.

Except material behavior different, particularly the different metal sheet cropped, that select according to stress of material thickness, also according to stress, select and zeugopodium frame section.

For can realize by framework section bar as far as possible unstressed join on the inner side of outer metal plate structure, these joints are implemented by laser welding.Framework section bar is level and preferably interconnecting by flash welding vertically to each other, because joint close bridge joint is proposed to higher requirement here.Here, larger heat adds not remarkable, because do not relate to and being connected of metal plate structure.

Preferably, the pillar footing of the framework section bar vertically extending is configured with the transverse section of section material of widening/increasing, to obtain the power of ring frame, flows applicable design.

Economical especially and save the production regulation of algorithm, the metal sheet of outer wall module is cropped and be engaged with each other into and make in modular walls, to produce for window and required the leaving a blank of door outside when metal sheet is bonded with each other.The extra high region of stress, for example, be adjacent to that window is left a blank or bight that door is left a blank, by larger intensity, for example the metal sheet of larger material thickness forms, all the other regions consist of the metal sheet compared with material thickness small intensity, for example less.In the extra high region of stress, in the outer metal plate structure of so manufacturing, there is not joint close.Therefore can manufacture stable but still there is the sidewall of light and as far as possible little material thickness and system height.

When outer wall module is bonded with each other, preferably first outer metal plate structure is connected with the end face of the docking of top flange section bar by I shape mating interface that is via metal sheet, make to produce the outside face without skew.Then other framework section bar is fixed on to outer metal plate structure by laser welding and if desired on the inner face of top flange section bar, wherein, horizontally extending stringer extends beyond the butt-welded side seam of outer metal sheet.Then being connected of the framework section bar in the outer wall module that preferably foundation combines with being integrated into of other by arc welding.

For inserting framework section bar advantageously, before engaging, preferably by laser beam cutting, the end rib being bonded on by T shape mating interface on the inner face of outer metal plate structure and/or top flange section bar cut or cut into, making to hold rib to be matched with the material shifts occurring and/or the shape that is matched with top flange section bar due to the different materials thickness of different metal plate on inner face.If sidewall manufactures in the level trend of side wall surface, have curve, vertical framework section bar must be matched with this curve equally.If the basic cross-sectional plane in compartment is along the longitudinal direction of underframe at distolateral convergent, corresponding coupling can may be also also essential or favourable for horizontally extending framework section bar section.

Substantially the skeleton of bearing for the reinforcing function of outer wall is preferably configured as, and makes to insert skeleton along framework section bar one body except the discontinuities for function opening of the first direction orientation of vertically extending in railroad car lateral wall.The section bar of the horizontal orientation transverse to this extension of skeleton is correspondingly interrupted by vertically-oriented section bar.In one embodiment, only along the function opening of horizontal orientation, form the section bar that is parallel to the level that function opening extends, make their cross over a plurality of in the section bar of the vertical extension of only being interrupted by function opening.In order to improve reinforcing, framework section bar preferably interconnects to each other.

Likely, the section bar of skeleton is clamped to separately and joins on outer metal plate structure.But can be proved to be advantageously, a plurality of single section bars are engaged in advance in an independent device, then they are placed on outer metal plate structure as prefabricated structural constituent.

During engaging process, each metal sheet of the outer metal plate structure of formation outer wall module is preferably inserted in auxiliary stand or supporting mould and for engaging process and is remained there.

In order to follow skeleton is fixed thereon or to build thereon, to stipulate in some embodiments, indivedual metal sheet, particularly the second metal sheets are provided with recess, and these recesses are not to extend on whole material thickness.Therefore outside face keeps not damaged.Therefore these recesses can for example be made with the form in groove, cutting or gap, can be for the docking seamed edge of framework section bar being navigated to here and being convenient to being connected of framework section bar and outer metal plate structure

Different from above-described mode of operation, also skeleton part can be fixed on each metal sheet of outer metal plate structure, then intactly make the outer metal plate structure of outer wall module.Advantage of the present invention and improvement project have partly been described.In addition, by the description of each embodiment of the present invention is drawn to other configuration and advantage.
