CAR BODY FOR A TRANSPORT VEHICLE AS WELL AS TRANSPORT VEHICLE AND MANUFACTURING METHOD

Description

[0001] The invention relates to a car body for the transport of goods or persons for a transport vehicle as well as a transport vehicle, in particular a rail vehicle, and a method for producing the transport vehicle with this car body.

[0002] A car body is the structure of a railway car, a railcar or a locomotive that is built on an underframe.

[0003] EP2619064A1 discloses a method for manufacturing a car body for rail vehicles, which has a floor and side walls extending upwards on opposite sides of the floor and, together with the floor and a cover, define an interior of the car body for the transport of persons and / or goods. A longitudinal beam extending in the longitudinal direction of the car body is provided in each transition area between the floor and the side walls to transmit longitudinal forces.

[0004] DE20214293U1 discloses a sliding-wall wagon with a loading space for transporting temperature-sensitive goods on the railway network. It states that conventional sliding-wall wagons are provided with insulation around the loading space, essentially consisting of insulating foam blocks that are inserted and glued into the cavities enclosed between the walls. However, it has been shown that the individual insulating foam blocks can become detached from one another or shift against one another during movement or impact during transport, thus compromising the insulation and creating thermal bridges.

[0005] DE20214293U1 proposes the construction of a car body whose loading space is surrounded on all sides by thermally insulated walls filled with foam in a sandwich construction. This measure allows the insulating foam to form such an intimate bond with the inner surfaces of the walls that it remains firmly adhered to the inner surfaces even under severe impacts and twisting, thus preventing gaps in the thermal insulation. The individual walls are provided as self-contained modules, which require surrounds to hold the inserted foam. Furthermore, a supporting structure is required into which the thermally insulated walls can be inserted.

[0006] CH367848A discloses a method for assembling prefabricated elements used for the construction of a car body of a railway carriage.

[0007] FR2613995A1 discloses a car body for a rail vehicle comprising an upper half-shell and a lower half-shell made of composite material. The present invention is therefore based on the object of providing an improved car body for a transport vehicle and a transport vehicle, in particular a rail vehicle, with this car body. Furthermore, a method for manufacturing the transport vehicle provided with this car body is to be specified.

[0008] The car body should be manufactured with reduced effort and cost. At the same time, the car body should have improved insulation properties.

[0009] The transport vehicle equipped with the car body should also be able to be manufactured cost-effectively with reduced effort. The production of the transport vehicle should be simplified and require less costly manual labor. Furthermore, the structure of the transport vehicle should be simplified, thus reducing production costs in this regard as well.

[0010] The car body should have an interior with at least one access opening, which can advantageously be closed by means of at least one sliding door.

[0011] This object is achieved with a car body according to claim 1, a transport vehicle according to claim 10 and a manufacturing method according to claim 11.

[0012] The car body intended for a transport vehicle comprises at least one lockable access opening and box modules that define the interior of the car body and each have an outer panel and an inner panel, as well as insulating material inserted between them. According to the invention, the interconnected outer panels form a self-contained outer shell, the interconnected inner panels form a self-contained inner shell, and the insulating material enclosed between them forms a self-contained insulating shell.

[0013] The inventive design of the box structure offers numerous advantages. By creating a self-contained outer shell, a self-contained inner shell, and a self-contained insulation shell inserted between them, optimal insulation is achieved. Thermal bridges can be completely avoided.

[0014] The individual box modules can be easily manufactured and cost-effectively connected to one another to create the car body. The box modules can be mass-produced cost-effectively and assembled in a modular fashion, then easily connected by joining the outer panels on the one hand and the inner panels on the other. The work is easy to perform because it only needs to be carried out on the inside or outside of the car body and not across the inside and outside of the car body. Since the box modules are largely automated in dedicated production facilities and can then be assembled and connected with relatively little effort, the amount of cost-intensive labor can be significantly reduced.

[0015] The box modules can be manufactured with high strength. The outer panels and / or inner panels are preferably made of sheet metal, aluminum sheet, preferably EN AW-5083 H321, stainless steel sheet, or glass fiber reinforced plastic. The insulation material is preferably polyurethane, polyurethane foam, or a material such as Divinycell H60 from the Diab Group, 252 21 Helsingborg, Sweden, or Xenergy HD300 Plus from Dow Chemical, or comparable products.

[0016] The material thickness of the outer shell or the outer panels is preferably in a range of 2.5 mm - 6 mm, preferably 4 mm + / - 10%.

[0017] The material thickness of the inner shell or inner panels is preferably in the range of 1.25 mm - 5 mm, preferably 2.5 mm + / - 10%. The specified material thicknesses of the outer and inner panels can be combined as desired, although the material thickness of the outer panels is generally greater.

[0018] The material thickness of the insulation shell is preferably in the range of 50 mm - 250 mm. The material thickness in the area of ​​the floor element is preferably 75 mm + / - 20%. The material thicknesses for the other box modules and the sliding door are preferably in the range of 65 mm - 180 mm.

[0019] The insulation material for the floor modules is preferably Divinycell H60, H80, or H130 from Diab Group, 252 21 Helsingborg, Sweden. The insulation material used for the other box modules and the sliding door is preferably Xenergy (RAVAGO XENERGY HD300-GV-Plus) from Dow Chemical.

[0020] The material thickness of the insulation shell is preferably a factor in the range of 25 - 60 higher than the material thickness of the outer panels or the inner panels.

[0021] The outer and inner panels, as well as the insulation material enclosed between them, of each box module are firmly connected to one another, resulting in box modules with high stability. According to the invention, the box modules are dimensioned such that the car body has a self-supporting structure after assembly of the box modules. The car body according to the invention can thus be mounted on a subframe of the transport vehicle, which, for example, has longitudinal beams resting on at least one running gear, without the need for additional load-bearing structural elements. This also results in a significant reduction in manufacturing effort and costs for the production of the transport vehicle, possibly a rail vehicle such as a freight car or a passenger car.

[0022] According to the invention, the box modules comprise at least one floor module, at least two wall modules, which may be connected to the floor module on both sides via connecting modules, and at least one ceiling module, which may be connected to the wall modules via connecting modules.

[0023] The at least one floor module, the two wall modules, the optionally present connecting modules, and the at least one ceiling module are preferably each connected to a front module on the end sides of the car body, which also has an outer plate and an inner plate as well as insulation material arranged therebetween.

[0024] The materials and material thicknesses used for the front modules preferably correspond to the materials and material thicknesses of the other box modules.

[0025] After installing the front modules, the result is a fully enclosed outer shell, a fully enclosed inner shell, and a fully enclosed insulation shell between them. The resulting outer shell, inner shell, and insulation shell are only penetrated by at least one access opening and, if applicable, window openings, thus ensuring optimal insulation and optimal stability of the car body.

[0026] The at least one access opening is preferably enclosed by a door frame and can be closed by a sliding door, which is guided along guide rails and can be lowered tightly into the door frame. The sliding door comprises an outer panel and an inner panel, between which insulation material is provided. The materials and material thicknesses used for the sliding door, the outer panel, the inner panel, and the insulation material preferably correspond to the materials and material thicknesses of the box modules.

[0027] The insulation material, preferably of all box modules and / or the sliding door, is preferably inserted as plastic foam or in one piece or in multiple pieces as solid insulation elements between the outer panels and the inner panels.

[0028] Preferably, the insulation elements are glued to the outer panels and the inner panels.

[0029] The insulation elements are preferably cut in such a way that the insulation shell results in a virtually gap-free result when the box modules are joined together.

[0030] Preferably, compressible insulation elements are provided that can be deformed in such a way that slightly oversized insulation elements fit tightly together after compression. The insulation elements can be oversized by 1% to 2%, for example.

[0031] The car body can be equipped with any fittings and devices on the inside or outside. Furthermore, partition walls can be anchored, preferably at any position within the car body. For this purpose, retaining rails are preferably integrated into the car body module.

[0032] The transport vehicle can be constructed easily and preferably has a conventional undercarriage with at least one running gear. Railway carriages preferably have two bogies as running gears, which are connected to each other by the undercarriage, which preferably has at least two continuous support profiles. The floor module can therefore be placed on the undercarriage and connected to it. For this purpose, the floor module is preferably provided with one or more connecting profiles, which preferably extend over the entire length of the floor module.

[0033] The assembly of the car body and the connection of the floor module to the undercarriage can be carried out in any number of steps. The car body can be constructed sequentially on the undercarriage, starting with the floor module. Alternatively, the car body can be partially or completely assembled and then placed on the undercarriage.

[0034] For this purpose, the at least one sliding door and the box modules for the preferably self-supporting car body are provided, comprising at least one floor module, at least two wall modules, optionally connecting modules, at least one ceiling module and two front modules, each having an outer plate and an inner plate, which are connected, preferably glued, with insulating material arranged therebetween.

[0035] The outer panels and the inner panels of the box modules are then connected to each other in any order chosen to form the outer shell and the inner shell, between which the self-contained insulation shell results.

[0036] Preferably, the outer plates and the inner plates are provided with connecting flanges on both sides and, if necessary, on the front, so that the associated connecting flanges of the outer plates and the associated connecting flanges of the inner plates can be easily connected to each other, if necessary glued, riveted, and welded. Thermally neutral joining methods are preferably used. The connecting flanges can be particularly advantageously fitted with Magna-Lok. ®< - Rivets are used to connect the connecting flanges. For this purpose, the connecting flanges are provided with concentric openings during the manufacture of the box modules or after the assembly of the box modules. Magna-Lok® rivets are inserted and tightened into these openings, closing the openings and creating stable connections between the connecting flanges.

[0037] The connecting flanges are preferably designed and arranged such that the lower connecting flange of the outer panel of an upper box module extends beyond the upper connecting flange of the outer panel of a lower box module. Rainwater can therefore never penetrate the joints between the connecting flanges, but is always diverted past the joint via the outer connecting flange.

[0038] Access openings provided in the car body are preferably provided with a door frame into which a sliding door can be tightly recessed. The sliding door is preferably movable along guide rails by means of carriages and is connected to the carriages by at least one rotating mechanism, by means of which the sliding door can be lowered into the door frame.

[0039] The invention is explained in more detail below with reference to the drawings. In the drawings: Fig. 1 a partially shown transport vehicle or a railway carriage 1 with a carriage body 10, which has interconnected box modules 11, 12, 13, 14, 15, namely a floor module 11, two wall modules 12, two connecting modules 13, two ceiling modules 14, as well as two front modules 15 and at least one sliding door 16 (see Fig. 7 ), each having an outer plate 111, 121, 131, 141, 151 and an inner plate 113, 123, 133, 143, 153, between which insulation material or a one-piece or multi-piece insulation module 112, 122, 132, 142, 152 is held (see Fig. 4a ); Fig. 2a a segment of the car body 10 of Fig. 1 , which has an outer shell 101 and an inner shell 103, between which an insulating shell 102 consisting of insulating material 112, 122, 132, 142, 152 is held; Fig. 2b the cross section through the car body 10 of Fig. 2a after removing the insulation cover 102 and exposing the insulation space 1020, which is intended to accommodate the insulation cover 102; Fig. 3a in spatial representation the cross section through the car body 10 of Fig. 2a after removal of the insulation cover 102 with the outer cover 101 and the inner cover 103; Fig. 3b a first connection point between inner plates 133, 143 of the inner cover 103; Fig. 3c a second connection point between inner plates 123, 133 of the inner cover 103 and a third connection point between outer plates 121, 131 of the outer cover 101; Fig. 3d a fourth connection point between inner plates 113, 123 of the inner cover 103 and a fifth connection point between outer plates 111, 121 of the outer cover 101; Fig. 3e the insulation cover 102 of Fig. 2a consisting of several suitably cut insulation elements 102x, 102y; Fig. 4a the segment of the car body 10 of Fig. 2a in a spatial exploded view with box modules 11, 12, 13, 14, namely a floor module 11, two wall modules 12, two connecting modules 13 and two ceiling modules 14, which are provided and connected to each other by connecting the elements of the outer shell 101 and the elements of the inner shell 103; Fig. 4b Parts of the two wall modules 12, the two connecting modules 13 and the two ceiling modules 14 of the car body 10 of Fig. 4a ; Fig. 4c one of the ceiling modules 14 of Fig. 4b in exploded view; Fig. 4 of one of the connection modules 13 of Fig. 4b in exploded view; Fig. 4e the floor module 11 of Fig. 4a ; Fig. 4fthe floor module 11 of Fig. 4a in exploded view; Fig. 4g one of the wall modules 12 of Fig. 4a with a view of the outer panel 121; Fig. 4h the wall module 12 of Fig. 4g in exploded view; Fig. 4 the wall module 12 of Fig. 4g with a view of the inner plate 121; Fig. 4jthe wall module 12 of Fig. 4f in exploded view; Fig. 5a facing parts of the floor module 11 and the wall module 12; Fig. 5b the interconnected parts of the floor module 11 and the wall module 12 of Fig. 5a ; Fig. 6 a part of the car body 10 of Fig. 1 with detached front module 15, which has an outer plate 151 and an inner plate 153 as well as insulation material 152 held therebetween; Fig. 7a a partially cut-away sliding door 16, which is held by lower and upper drives 94, 95 displaceably along guide rails 98, 99, with a rotating mechanism 5, 52, by means of which the sliding door 16 can be lowered into the door frame 96 of the access opening 90; and Fig. 7b part of a crankshaft 52 of the rotating mechanism 5 of Fig. 7a , which is connected to the upper drive 95 via an articulated lever 53.

[0040] Fig. 1 shows the front half of a railway carriage 1 with an underframe 6, onto which a car body 10 according to the invention is mounted. The underframe 6 comprises two longitudinal beams 61 and is provided at the front and rear with a running gear or bogie (not shown). The rear half of the railway carriage 1, which has been cut away, is preferably constructed in the same way as the front half.

[0041] Access openings 90 are provided on the opposite side walls of the railway carriage 1, which are enclosed by a door frame 96 and preferably each closed by means of a sliding door 16 according to Fig. 7 are lockable. The sliding door 16 is held by lower drives 94, which are movable along a lower guide rail 98, and upper drives 95, which are movable along an upper guide rail 99. The sliding door 16 can be moved along the straight guide rails 98, 99 in front of the respective access opening 90 and can be lowered into the door frame 96 by means of a rotating mechanism 5, 52. The sliding door 16 can be locked by means of a locking mechanism having locking rods 51. The locking rods 51 can be inserted into locking parts 91, which are provided in the door frame 96 (see Fig. 7 ). In this embodiment, the locking mechanism is integrated into the rotating mechanism 5.

[0042] The car body 10 is modular in design and comprises several box modules 11, 12, 13, 14, 15. In the embodiment shown, a single-part or multi-part floor module 11 is provided, to which vertically aligned wall modules 12 are connected on both sides, which are connected to horizontally aligned ceiling modules 14 via inclined connecting modules 13. On each side of the car body 10, a structure with a wall module 12, a connecting module 13, and a ceiling module 14 is therefore provided. On both ends, the car body 10 is closed off by a front module 15. The connecting lines 21, 22, 23, 24, 25 between the aforementioned box modules 11, 12, 13, 14, 15 are in Fig. 1 marked.

[0043] The cross-section of the car body 10 as well as the number and division of the box modules can be freely selected and is adapted to the design of the transport vehicle 1.

[0044] The box modules 11, 12, 13, 14, and 15 can be manufactured separately in series production with minimal labor and cost. For example, five production lines are planned, each of which will manufacture one of the box modules 11, 12, 13, 14, and 15. Time-consuming manual production in an assembly hall is therefore replaced by cost-effective automated production in a production hall. The costs for manufacturing a car body 10 or transport vehicle 1 can therefore be significantly reduced. This is particularly true because the stable box modules 11, 12, 13, 14, and 15 can be used to build a self-supporting car body 10. This means that the transport vehicle 1 requires no additional load-bearing structural elements besides the undercarriage 6 and the car body 10.A large portion of the manufacturing work for transport trolley 1 can therefore be relocated from a production hall where the transport trolleys are assembled to a production facility where the box modules 11, 12, 13, 14, and 15 can be efficiently manufactured to a high standard. The manufacturing work in the workshop where the transport trolleys 1 are completed is therefore limited to the assembly of the box modules 11, 12, 13, 14, and 15 and the subsequent installation of the fittings.

[0045] The box modules 11, 12, 13, 14, 15 each comprise an outer plate 111, 121, 131, 141, 151 and an inner plate 113, 123, 133, 143, 153, between which insulation material 112, 122, 132, 142, 152 is held (see Fig. 4a The outer panels 111, 121, 131, 141, 151 and / or the inner panels 113, 123, 133, 143, 153 are preferably made of sheet metal, aluminum sheet, preferably EN AW-5083 H321, preferably stainless steel sheet, or glass fiber reinforced plastic. The insulation material or the small-piece or multi-piece insulation modules 112, 122, 132, 142, 152 are preferably made of polyurethane, polyurethane foam, or a material such as Divinycell H60, H80, H130 from the Diab Group, 252 21 Helsingborg, Sweden, or Xenergy (RAVAGO XENERGY HD300-GV-Plus) from Dow Chemical, or comparable products. The insulation materials mentioned have a high strength and give the box modules 11, 12, 13, 14, 15 together with the outer plate 111, 121, 131, 141, 151 and the inner plate 113, 123, 133, 143, 153 a high strength and load-bearing capacity.

[0046] The insulation material 112, 122, 132, 142, 152, which was inserted in the form of cut insulation elements or in the form of a hardening plastic foam between the outer plates 111, 121, 131, 141, 151 and the inner plates 113, 123, 133, 143, 153, is firmly connected to them, preferably glued. Suitable adhesives include polyurethane adhesives, which belong to the group of reactive adhesives and are addition-curing. The polymers offer a range of properties from low cross-linking (elastomers with high elongation at break) to highly cross-linking (thermomers). An adhesive with cross-linking is selected that allows for the thermal expansion of the metal plates typically occurring during operation of the transport vehicle 1 without detachment or cracking.

[0047] Fig. 2a shows a segment of the car body 10 of Fig. 1 , which was realized by joining the box modules 11, 12, 13, 14, 15. By connecting the outer panels 111, 121, 131, 141, 151 on the one hand and the inner panels 113, 123, 133, 143, 153 of the box modules 11, 12, 13, 14, 15 on the other hand, a self-contained outer shell 101, a self-contained inner shell 103, and a self-contained insulation shell 102 were created. At the connection points 21, 22, 23, 24, the connections of the outer panels 111, 121, 131, 141, 151 are separated from the connections of the inner panels 113, 123, 133, 143, 153 by the self-contained insulation shell 102, so that thermal bridges are avoided.

[0048] It is illustrated that, in preferred embodiments, the insulation shell 102 consists of insulation elements 102x, 102y, which are tailored such that the insulation shell 102 is realized without gaps and crevices. The complete separation of the outer shell 101 from the inner shell 103 by the insulation shell 102, preferably over the entire length of the car body 10, achieves optimal insulation of the interior 100 of the car body 10.

[0049] In Fig. 2a It is further shown that any fittings, devices and apparatus, such as rails 18, shelves 192, fans or cooling devices 191 can be advantageously attached to the inner shell 103.

[0050] Fig. 2b shows the cross section through the car body 10 of Fig. 2a after removing the insulation cover 102 and exposing the insulation space 1020, which is intended to accommodate the insulation cover 102. It can be seen that the insulation space 1020 is completely closed and no thermal bridges are present.

[0051] Fig. 3a shows in spatial representation the segment of the car body 10 of Fig. 2a after removal of the insulation sleeve 102 with the self-contained outer sleeve 101 and the self-contained inner sleeve 103. It is shown that, on the one hand, the mutually facing end pieces of the outer plates 111, 121, 131, 141, 151 and, on the other hand, the mutually facing end pieces of the inner plates 113, 123, 133, 143, 153 overlap each other and are connected to each other by mechanical joining methods, clinching, riveting, punch riveting, welding and / or chemical joining agents, such as plastic adhesives or metal adhesives.

[0052] Fig. 3b shows a first connection point between inner plates 133, 143 of the inner shell 103, which are connected to each other, for example, by punch rivets.

[0053] Fig. 3c shows a second connection point between inner plates 123, 133 of the inner shell 103 and a third connection point between outer plates 121, 131 of the outer shell 101, which are connected to each other by punch rivets and / or metal adhesives.

[0054] Fig. 3d a fourth connection point between inner plates 113, 123 of the inner shell 103 and a fifth connection point between outer plates 111, 121 of the outer shell 101 of the floor element 11 and a side wall 12. It is also shown that any mounting elements can be mounted on the outer wall of the car body 10, such as those in Fig. 1 Guide rails 98, 99 shown or those in Fig. 3d shown connecting profiles 118 on the underside of the floor module 11, which can be connected to the base frame 6.

[0055] Fig. 3e shows the insulation cover 102 of Fig. 2a Consisting of several appropriately cut insulation elements 102x, 102y. Recesses 1120, 1121 are formed in the insulation shell 112, which serve to accommodate fittings or rails 18 or corresponding recesses in the inner plate. The insulation elements 102x, 102y are cut to size and, if necessary, glued together so that the insulation shell 102 has as few gaps as possible, ensuring optimal insulation for the SBB 20-03 EP. The insulation material 112, 122, 132, 142 of the box modules 11, 12, 13, 14 is selected such that when the box modules 11, 12, 13, 14 are joined together, all gaps close automatically, preferably through slight deformation of the preferably slightly oversized insulation material 112, 122, 132, 142.

[0056] Fig. 4a shows the segment of the car body 10 of Fig. 2a in a spatial exploded view with box modules 11, 12, 13, 14, namely a floor module 11, two wall modules 12, two connecting modules 13 and two ceiling modules 14, which are provided and connected to one another on the one hand by connecting the mutually facing end pieces of the outer panels 111, 121, 131, 141, and on the other hand by connecting the mutually facing end pieces of the inner panels 113, 123, 133, 143, 153. The outer panels 111, 121, 131, 141 are provided on both sides and, if necessary, entirely with end pieces or connecting flanges 1111, 111F; 1211, 1212; 1311, 1312; 1411, 1412 and the inner plates 113, 123, 133, 143, 153 are provided on both sides and, if necessary, fully with end pieces or connecting flanges 1131; 1231, 1232; 1331, 1332; 1431, 1432, which are connected to each other in pairs, if necessary joined, riveted, welded or glued.

[0057] The lower connection flange 1411 of the outer plate 141 of the ceiling module 14 covers the upper connection flange 1312 of the outer plate 131 of the underlying connection module 13 to the outside.

[0058] The lower connection flange 1311 of the outer plate 131 of the connecting module 13 covers the upper connection flange 1212 of the outer plate 121 of the underlying wall module 12 to the outside.

[0059] The lower connecting flange 1211 of the outer plate 121 of the wall module 12 covers the connecting flange 1111 of the outer plate 111 of the underlying floor module 11 to the outside.

[0060] The outer plate 141, 131, 121 of a higher box module 14, 13, 12 therefore covers the outer plate 131, 121, 111 of the box module 13, 12, 11 located below it.

[0061] Fig. 6 shows that the car body 10 or the box modules 11, 12, 13, 14 also have connecting flanges 111F, 113F; 131F, 141F on the front side, which can be connected to connecting flanges 1511, 1531 of the front modules 15 in the same way, mechanically and / or chemically, in order to close the outer shell 101 and the inner shell 103 also at the front.

[0062] The connecting flanges are designed in such a way that after the box modules 11, 12, 13, 14, 15 have been joined together, they overlap each other in pairs and can be easily connected to each other using the connection methods described.

[0063] Fig. 4b shows parts of the two wall modules 12, the two connecting modules 13 and the two ceiling modules 14 of the car body 10 of Fig. 4a It can be seen that the lower connecting flanges 1311, 1331 of the intermediate modules 13 project downwards beyond the insulation material or insulation module 132 and can thus engage over the upper end piece of the facing wall module 12. The intermediate module 13 can thus be placed or plugged onto the wall module 12, resulting in a stable mechanical connection even before the connecting flanges or end pieces 1311, 1331; 1212, 1232 of the outer panels 131, 121 and inner panels 133, 123 are mechanically and / or chemically connected to one another.

[0064] Preferably, therefore, the two ceiling modules 14 are first connected to each other and then to the connecting modules 13, after which the extended ceiling module 13-14-14-13 is placed on the already installed wall modules 12-12.

[0065] The front modules 15 are then connected to the already installed box modules 11, 12, 13, and 14. Depending on the circumstances, a different order for connecting the box modules 11, 12, 13, 14, and 15 may be appropriate.

[0066] Fig. 4b further shows that, in addition to the connecting flanges, additional connecting plates 19 can be provided in order to facilitate and / or reinforce the connections.
