Abstract

In a rail vehicle with a modular-construction body (2), individual major modules (5-8) like floor, roof and side-wall modules and possibly end-wall modules or a driving cab are first made, assembled and fitted out, operationally tested and then joined together in the region of adjacent side edges (19) by a cold or low-heat method.

Description

The invention relates to a rail vehicle according to the Preamble of the first claim.

In a known rail vehicle of this type (WO 93/19965) is the body of a floor module and an as Comprehensive unit manufactured side walls and ceiling wall Module formed. With this construction, the floor module is included assembly is freely accessible, but results in Manufacture of the module to be placed on it the same Difficulties as if the upper module is directly on the Floor module would be built.

The invention is based, with one Rail vehicle according to the preamble of the first claim Take measures that make production easier enable.

This object is achieved according to the invention by the characteristic features of the first claim.

When building a particularly the passenger transport serving rail vehicle according to the invention individual wall units of the car body manufactured for themselves and at the interfaces to neighboring modules the necessary mechanical and where necessary, too electrical, pneumatic, hydraulic or optical Lanyards for the coupling when joining them Modules equipped. The individual modules are therefore as in essentially flat or only a little in cross-section configured elements that are in the for a necessary operation, especially during assembly or best position in module production can. The modules can therefore be assembled be completely assembled, for example with the assigned window, ventilation, lighting, Public address, pneumatic, air conditioning, display, control and Like. Components are equipped. You can also completely varnished or surface treated in another way when cold joining processes such as riveting, Locking ring or screw connector for joining the Modules are used. When using hot joining processes, it is especially a laser welding process expedient, the edge areas to be welded initially without Let surface treatment so that only these strips after the hot joining process to a surface treatment undergo. This allows a high one Achieve a degree of integration in the individual modules, with the additional possibility of prefabrication of individual Modules given regardless of the assembly status of other modules is. In addition, the at least largely pre-assembled individual modules for quality and / or Function are checked, eliminating errors due to the free accessibility of the respective module to one Shortening the time required. The optimal quality is can therefore be achieved with less time, also with final inspection and commissioning only errors in Area of the joints are to be found. Because of the independent Possibility of manufacturing the individual modules in parallel work processes are also shortened Lead times in vehicle manufacturing and assembly.

The basic components of the modules can be in differential or Sandwich construction from outer wall, support elements and inner wall be built that are firmly connected can, however, also in an integral design, in particular extruded profile parts apply, preferably from Aluminum exist and according to the outer dimensions of the Modules are dimensioned. Extruded profile parts can especially with profile formations such as C-rails, grooves, Bridges, channels and the like. Be equipped, preferably run in the longitudinal direction of the car body to be formed and those for carrying water, compressed air, electrical cables or other equipment such as air conditioning elements, Lighting elements or the like. As well as for building or for the assembly of components such as devices, extension parts, seats, Ashtrays can serve. The profile formations are in particular on the inner walls and preferably arranged between the outer and inner walls, so that an at least largely smooth surface to the inside of the Carriage body can represent. Channel formations can have openings to the inside of the car body, to be able to supply or remove heating or cooling air. For the Representation of continuous, especially rounded transitions between the roof module and side walls are appropriate Longitudinal edges of the outer wall of the roof module, preferably with a radius directed downwards or bent so that either welding the opposing longitudinal edges of the module is made possible or an interlocking or overlap these edges and join through Cold joining techniques becomes possible. The inside walls of the modules can be designed so that an at least largely hidden connection possibility is created, the Connection points through cover strips or functional modules, how to hide luggage racks. Also the Longitudinal edges of the inner wall of the roof module can in Bow should be directed downwards, it being advisable these longitudinal side margins in the horizontal direction at a distance from the adjacent inner walls of the side wall modules to run, so that in the gap thus formed For example, a profile web open at the bottom is used can be an optimal one, from the inside of the car body from at least largely concealed connection possibility offers.

A reliable connection of the side wall modules with the Floor module results, for example, if the on the body bottom longitudinal edges of the load-bearing structural components, especially the outer walls of the side wall modules protrude beyond the longitudinal side edges of the associated inner walls and with the respectively adjacent longitudinal side edges of the Floor module are tightly and firmly connected. You can also the long side edges of the floor module down parallel to the adjacent long side edges of the side wall modules be angled so that it is enlarged Area stable and reliable connection between the floor module and the rest of the body structure guaranteed.

If with the modules a rail vehicle with a driver's cab at least one end wall module is expedient to be built up expanded to such a cab. It is it is useful if the floor module and the side wall modules protrudes beyond the roof module at least at one longitudinal end, so that the driver 's cab is on the towering section of the Floor module is supported.

When manufacturing the modules it is possible to like the interior the outer wall of the side wall modules closed over design and necessary window and door openings or the like. only during the further processing of the module in question bring in. The side wall modules can also consist of several in the installed position on one level one above the other and on their longitudinal side edges joined to each other extruded profiles be built, with partial strand profiles in the area of doors, windows and the like there from the outset can be cut accordingly. Here, the basic module component the corresponding processing machines in the the most convenient location for the work process. At the production of a rail vehicle is expedient proceed in such a way that the modules, at least largely for themselves completely completed, checked and then to be put together successively, then their fixed Connection at adjacent longitudinal side edges can be executed. It is useful that Assembling disruptive installation of large equipment, seating and The like. Final equipment only after completion of the joining process carried out.

The invention is based on the sketches of a Embodiment explained in more detail.

A rail vehicle 1 has a body 2, which Bogies 3, such as powered bogies or simple bogies, are mounted The end car of a train is car body 2 a driver's cab 4 is assigned on the end face (FIG. 5).

1, the car body consists of a floor module 5, a ceiling module 6 and two in particular the same and thereby Sidewall modules 7 constructed in mirror image, which are but also through different, asymmetrical arrangement of the Can distinguish recesses. These large modules 5, 6, 7 each extend in one piece over the entire length of the Rail vehicle, unless a cab is provided. If the cab is available, the same can be made from small modules be built up as a cab hood 8 or cab rear wall 9 can be formed with control cabinets 10. in the If necessary, can also be analogous to the rear cab wall 9 Front wall modules provided in the end area of individual car bodies become. For the individual modules are preferred cut extruded profile parts used, in particular are made of aluminum. On such extruded profile parts can in particular be useful profile formations such as grooves, C-rails, webs and channels be preferably in the longitudinal direction of the car body 2 run. Insulations, Inner wall linings 11 of the side wall modules 7, a ceiling lining 12 of the ceiling module 6 or a Floor 13 of the floor module 5 are fixed. In molded Grooves can control electrical or fluidic Supply lines must be installed, including molded ones Channels can serve. Such channels can, for example directly as control or supply lines for air, Water or the like can be used. The individual modules 5 to 8 are as large as possible as building blocks prefabricated, which results in a minimal assembly effort the free accessibility of the individually manufactured modules simplified logistics and ergonomic employment relationships results. There are also significantly reduced testing and commissioning efforts as well as times for the entire vehicle achieve because the individual modules are completely pre-checked can. It is useful to electrical at the ends like fluidic lines corresponding coupling means to be provided with adapted continuations of the corresponding lines in other modules correspond. High quality is also achieved because of occurring Errors can already be eliminated on the module, where a better accessibility with little disassembly and assembly is possible and there is practically no increase in lead time for the entire vehicle. It puts there is also a drastic reduction in lead time due to the Possibility of assembling and testing the modules in parallel and thus a reduced capital commitment than if that Rail vehicle is built in a conventional manner. The Individual modules 5-8 can be painted or finished otherwise be surface treated. The so finished Modules are then built in a modular system put together. The modules are joined e.g. by cold joining techniques, preferably in the manner of Locking ring or rivet connections, whereby locking ring bolts in a special way as a permanent connection prove. The modules are thus detachably assembled, after such lanyards with relatively simple Have facilities removed. In itself, the modules also be constructed as welded assemblies.

In particular, the side wall modules 7 and the ceiling wall module 6 are built with two shells, at least the outer wall 7.1 or 6.1 and a spaced inner wall, which the inner lining 11 or the ceiling inner lining 12 bears, are in one piece. Profiling will be preferably between the outer wall 6.1 or 7.1 and the associated inner wall 12 and 11 and are preferably provided on the inner walls 11, 12. Profiling 3 can e.g. in the roof module 6 as Channels 14 or be formed as groove 15. Becomes a duct used as air duct, then this duct with at least one opening to the inside of the car body 2 be provided in order to supply warm or cold air to be able to dissipate. At least in the ceiling module 6, but possibly lighting elements can also be in the side wall modules 7 16, PA elements 17 or the like. Integrated. Also can cutouts for windows 17 in the side wall modules 7 or doors 18 cut and these components 17, 18th be used.

The completely assembled and before assembly especially with the respective assigned windows - (17), Ventilation, lighting (16), heating, cooling, display, Control and / or the like. Components equipped and finished or surface-treated modules at Assembly in its prescribed assembly position, wherein line connections and the like. Are carried out. Then the side wall modules 7 with the ceiling wall module 6 and the floor module 5 along each other adjacent longitudinal side edges 19 of the outer walls 6.1 and 7.1 firmly and tightly connected. If the connection is not done according to the type of riveting, but for example is carried out in the laser welding process, then not narrow strips along the long side edges 19 finished or surface treated. This narrow Strips can be welded and plastered Welds at the installation site still the necessary surface treatment experienced or through cover strips, adhesive strips, Films and the like are covered.

To enable a reliable joint connection, the Longitudinal edges 19 of the outer wall 6.1 of the roof module 6 after directed or bent below. The longitudinal side edges 19 of the Roof module such as the side wall module can then Butt welding butt joint or when using a cold connection in the manner of riveting overlap enough width. Thereby necessary Rivet holes already in the relevant edge strip of the associated longitudinal side edges may be provided. Also the Longitudinal edges 20 of the inner wall 12 of the roof module 6 are bent down in such a way that in the body 2 Longitudinal edges 20 in the horizontal direction from the adjacent longitudinal side edges 20 of the inner walls 11 of the Sidewall modules 7 are spaced and in vertical Overlap direction. In the gap between them the adjacent side edges 20 of the inner walls 11, 12 can thereby one connecting means 21, e.g. one down open U-profile web or ventilation duct are used, which is fixed on the associated longitudinal side edges 20. This results in an optical possibility concealed arrangement of rivets, screws or the like. Fasteners.

In the area of the floor module 5 are the ones pointing downwards Longitudinal edges 19 of the outer walls 7.1 formed so that the longitudinal side edges 20 of the associated inner walls 11 protrude downwards. These lower longitudinal side edges 19 are with corresponding longitudinal side edges 19 of the floor module 5 tight and tight by rivet-like connecting means or connected by welding. Here are the long edges 19 of the floor module downwards parallel to the neighboring ones Longitudinal edges 19 of the side wall modules 7 angled, see above that there is sufficient overlap area for the connecting means and thus a reliable, rigid attachment of the upper modules 6, 7 with the floor module 5 is guaranteed.

For the attachment of a driver's cab 4, according to FIG Floor module 5, the side wall modules 7 and the roof module a longitudinal end, so that on the remaining front section of the floor module 5 the driver's cab 4 can be put on. One that closes the body 2 End wall 9 represents the link between the Carriage body 2 and the driver's cab 4.

After assembling modules 5-8, the final equipment takes place of the respective rail vehicle, for example by Seats 22 fixed to floor module 5 and pre-tested Transformers, air conditioners, electrical control units and Like. Be installed. Then it's just that Functional test of the entire vehicle and its Commissioning required.

The modules are used for processing in fixtures added that an optimal for each work process Working situation, especially in ergonomic terms enable.
