[0002] Rail vehicle with functional module and method for mounting a functional module in a rail vehicle

[0003] In the field of railway technology, it is common practice to equip rail vehicles equipped with a drive system with functional modules. Such functional modules can include functional units such as compressors, compressed air reservoirs, or brake control modules.

[0004] It is also known to equip rail vehicles with ballast plates in order to achieve a desired total weight with regard to the traction behavior of the rail vehicles and a desired weight distribution with regard to the vehicle trim.

[0005] The invention is based on the object of specifying a rail vehicle which enables the retrofitting of ballast plates in a particularly simple and also particularly space-saving manner.

[0006] This object is achieved according to the invention by a rail vehicle having the features according to claim 1. Advantageous embodiments of the rail vehicle according to the invention are specified in the subclaims.

[0007] According to the invention, the functional module comprises a base plate which is designed to be stackable on the at least one ballast plate and which rests on the at least one ballast plate to form a plate stack.

[0008] A significant advantage of the rail vehicle according to the invention is that the stackability of the functional module provided according to the invention enables particularly simple subsequent installation of an additional ballast plate, for example by removing the functional module from the underlying ballast plate by lifting the base plate, placing the additional ballast plate on the already existing ballast plate and then placing the base plate of the functional module on the additionally inserted ballast plate.

[0009] A further advantage of the rail vehicle according to the invention is that the possibility of inserting the additional ballast plate between the already existing ballast plate and the base plate of the functional module can advantageously lead to a particularly space-saving plate stack and thus to a particularly space-saving overall arrangement.

[0010] In an embodiment variant considered to be advantageous, it is provided that the base plate has at least one through-hole, the ballast plate has at least one through-hole which is aligned with or at least overlaps the at least one through-hole of the base plate, and a securing element extends through the two overlapping through-holes and prevents displacement of the base plate on the ballast plate at least in the horizontal plane.

[0011] The securing element can be, for example, a screw which is screwed into a thread in a floor structure of the rail vehicle, a threaded rod or a stud bolt.

[0012] It is advantageous if the securing element also prevents the base plate from being lifted off the ballast plate and / or from being lifted off the floor structure of the rail vehicle located beneath the ballast plate.

[0013] The at least one ballast plate can be the upper ballast plate of a ballast plate stack. In the latter case, it is advantageous if each of the ballast plates of the ballast plate stack has at least one through-hole which is aligned with or at least overlaps the at least one through-hole of the base plate, and the securing element extends through the overlapping through-holes of all the ballast plates to a floor structure of the rail vehicle and prevents displacement of the base plate and the ballast plate stack relative to the floor structure of the rail vehicle.

[0014] The securing element preferably also prevents the base plate and the ballast plate stack from lifting off the floor structure of the rail vehicle.

[0015] It is particularly advantageous if the base plate has two or more through holes, the ballast plate or in the case of a ballast plate stack all ballast plates have a through hole for each through hole in the base plate which is aligned with or at least overlaps the corresponding through hole in the base plate, and a securing element extends through each of the overlapping through holes, which prevents the base plate from being displaced relative to the floor structure of the rail vehicle and / or from being lifted off the floor structure of the rail vehicle.

[0016] The functional module preferably comprises one or more functional units that are permanently mounted on the base plate.

[0017] The functional module is preferably transportable in its entirety, i.e. including the functional unit or all functional units, simply by moving the base plate.

[0018] The functional unit or at least one of the functional units is preferably a compressor, a compressed air tank or a brake control module.

[0019] The connection of the functional units to external components is preferably carried out via mechanically flexible connection components, for example flexible hoses or flexible cables, in order to ensure the possibility of subsequently inserting additional ballast plates and of subsequently reconnecting the base plate of the functional module - at a higher vertical level - to the external components using the same connection components.

[0020] The base plate preferably has at least one transport interface which enables the attachment or placement of a lifting tool for lifting the base plate and for transporting the base plate and thus the functional module as a whole.

[0021] The base plate and the ballast plates are preferably identical or preferably differ only in that the base plate has one or more additional fastening holes for attaching one or more functional units and / or one or more transport interfaces.

[0022] The rail vehicle is preferably a locomotive.

[0023] The function of the ballast plate(s) is preferably exclusively to increase the mass of the rail vehicle for the purpose of trimming and / or increasing traction.

[0024] The mass of the ballast plate(s) and the base plate is preferably at least 100 kg each.

[0025] The invention also relates to a method for mounting a functional module in a rail vehicle which is equipped with a drive and at least one ballast plate whose function is to increase the mass of the rail vehicle. According to the invention, with regard to the method, it is provided that a base plate of the functional module which can be stacked on the ballast plate is placed on the ballast plate to form a plate stack. With regard to the advantages of the method according to the invention and advantageous embodiments of the method according to the invention, reference is made to the above statements in connection with the rail vehicle according to the invention and its advantageous embodiments.

[0026] In a variant of the design considered advantageous, it is provided that the ballast plate onto which the base plate is placed to form the plate stack is a subsequently mounted second ballast plate and, before the functional module is mounted on the second ballast plate, the base plate of the functional module rests on a previously mounted first ballast plate and forms a temporary stack with it.

[0027] In the context of mounting the functional module on the second ballast plate, it is preferably provided that the base plate of the functional module is lifted from the first ballast plate and the first ballast plate is exposed, the second ballast plate is placed on the exposed first ballast plate and the base plate of the functional module is then placed on the second ballast plate to form the plate stack which is higher than the temporary stack.

[0028] It is advantageous if the base plate has at least one through-hole and the first and second ballast plates each have a through-hole corresponding to the through-hole in the base plate, wherein, before the functional module is mounted on the second ballast plate, the base plate of the functional module rests on the first ballast plate in such a way that the through-hole in the base plate is aligned with or at least overlaps the corresponding through-hole in the first ballast plate. After the first ballast plate has been exposed, the second ballast plate is preferably placed on the exposed first ballast plate in such a way that the through-hole in the first ballast plate is aligned with or at least overlaps the through-hole in the second ballast plate.The base plate of the functional module is preferably placed on the second ballast plate in such a way that the through hole of the base plate is aligned with the through holes of the first and second ballast plate or at least overlaps them.

[0029] After or during assembly of the base plate on the second ballast plate, mechanical securing is preferably carried out by inserting a securing element through each of the overlapping through holes, which prevents the base plate from shifting relative to the floor structure of the rail vehicle and / or the base plate from lifting off the floor structure of the rail vehicle. Such securing elements can, for example, be formed by stud bolts or threaded rods that are firmly attached to the floor structure (e.g. screwed or welded), onto which the through holes of the ballast plates and the base plate are pushed; alternatively, such securing elements can also be formed by screws that, after the plates have been stacked, are pushed through the overlapping through holes and screwed to the floor structure of the rail vehicle.

[0030] With regard to the insertion of additional ballast after the functional module has already been installed on the first ballast plate, it is considered advantageous if the rail vehicle is weighed with the temporary stack before the second ballast plate is installed and the installation of the second ballast plate is made dependent on the result of the weighing indicating that adding further ballast in the form of the second ballast plate for the purpose of increasing traction and / or trimming is necessary or advantageous.

[0031] The invention also relates to a functional module for installation in a rail vehicle, which is equipped with a drive and at least one ballast plate whose function is to increase the mass of the rail vehicle. With regard to the functional module, the invention provides that the functional module comprises a base plate designed for stacking on the ballast plate.

[0032] With regard to the advantages of the functional module according to the invention and advantageous embodiments of the functional module according to the invention, reference is made to the above statements in connection with the rail vehicle according to the invention and its advantageous embodiments as well as to the above statements in connection with the method according to the invention and its advantageous embodiments.

[0033] The invention is explained in more detail below using exemplary embodiments, which show, by way of example:

[0034] Fig. 1 shows an exemplary embodiment of a rail vehicle according to the invention in a simplified cross-sectional view,

[0035] Figure 2 shows a section of the rail vehicle according to Figure 1 in more detail, with a floor structure, two ballast plates and a functional module being shown in an enlarged view,

[0036] Figure 3 shows the section according to Figure 2 for comparison without securing means,

[0037] Fig. 4-10 a first embodiment of a method for producing the rail vehicle according to Figure 1 or the arrangement according to Figures 2 and 3, and

[0038] Fig. 11-19 show a second exemplary embodiment of a method for producing the rail vehicle according to Figure 1 or the arrangement according to Figures 2 and 3. For the sake of clarity, the same reference numerals are always used in the figures for identical or comparable components.

[0039] Figure 1 shows, in a schematic cross-sectional view, components of an exemplary embodiment of a rail vehicle 10 according to the invention. The rail vehicle 10 is, for example, a locomotive.

[0040] The rail vehicle 10 comprises a drive 11 and a floor structure 12, on which two ballast plates 20 and 30 and a functional module 50 rest. The two ballast plates 20 and 30 and the functional module 50 are secured to the floor structure 12 by positive and / or frictional engagement against displacement in the horizontal plane and preferably also against lifting in the vertical direction.

[0041] Figure 2 shows the arrangement formed from the floor structure 12, the two ballast plates 20 and 30 and the functional module 50 in an enlarged view in more detail.

[0042] In the exemplary embodiment according to Figures 1 and 2, the functional module 50 comprises two functional units, one of which is formed by a compressor 51 and the other by a compressed air tank 52. Alternatively or additionally, the functional module 50 can also comprise a brake control module or another module necessary or advantageous for a rail vehicle 10.

[0043] Furthermore, the functional module 50 comprises a base plate 53 that supports the aforementioned functional units. The base plate 53 is designed to be so stable that it allows the functional module 50 to be lifted and transported simply by lifting and moving the base plate 53.

[0044] The two ballast plates 20 and 30 located under the base plate 53 are preferably of identical construction and each have one or more through holes 60 which are aligned one above the other when the ballast plates 20 and 30 are stacked in alignment and which make it possible to connect the ballast plates 20 and 30 to one another in a form-fitting and / or force-fitting manner by means of securing means, for example fastening means such as fastening screws 70 (see for example Figure 2), bolts or threaded rods 200 (see for example Figures 11 to 19).

[0045] The base plate 53 preferably also has two or more through holes 60, each of which is aligned with a corresponding through hole 60 in the ballast plates 20 and 30 and makes it possible to connect the base plate 53 to the two ballast plates 20 and 30 located underneath in a form-fitting and / or force-fitting manner.

[0046] 1 and 2, the base plate 53 is aligned on the two ballast plates 20 and 30 with respect to the through holes 60 and is connected to them in a force-locking and form-locking manner by means of appropriately long fastening screws 70. The fastening screws 70 are screwed into appropriately arranged threads 80 which are introduced into the floor structure 12 of the rail vehicle 10. In the embodiment shown in Figures 1 and 2, each of the fastening screws 70 or each of the securing means therefore extends through a through hole 60 in the base plate 53 of the functional module 50 and through the through holes overlapping therewith in the ballast plates 20 and 30 located underneath.

[0047] Figure 3 shows the arrangement according to Figure 2 for better understanding without the securing means or fastening screws 70 shown in Figure 2.

[0048] Figures 4 to 10 show an exemplary embodiment of a method for producing the arrangement shown in Figures 1 to 3. Figure 4 shows the floor structure 12 shown in Figures 1 to 3 after the lower ballast plate 20 has been placed on the floor structure 12 in such a way that the through holes 60 of the lower ballast plate 20 are aligned with the threads 80 in the floor structure 12.

[0049] Figure 5 shows the arrangement after the functional module 50 has been placed on the lower ballast plate 20. The base plate 53 of the functional module 50 is placed in such a way that the through holes 60 of the base plate 53 of the functional module 50 are aligned with the through holes 60 of the ballast plate 20 located below.

[0050] Figure 6 shows the arrangement after the functional module 50 has been screwed to the underlying ballast plate 20 and the floor structure 12 by means of suitably dimensioned securing elements in the form of correspondingly matching short fastening screws 90. The length of the short fastening screws 90 is preferably adapted to the thickness of the plate stack such that the screw head of the fastening screws 90 can exert a contact force on the base plate 53 and press it together with the underlying ballast plate 20.

[0051] If, for example, after weighing the rail vehicle 10, it is determined that its weight is too low or the weight distribution of the rail vehicle 10 is not optimal, one or more additional ballast plates, for example the upper ballast plate 30 shown in Figures 1 to 3, can be subsequently mounted. During this subsequent assembly, the functional module 50 is first lifted - as shown in Figure 7 - and - if desired - moved horizontally away from the lower ballast plate 20.

[0052] The lifting of the base plate 53 can occur, for example, after a lifting tool has been attached to or fastened to one or more transport interfaces of the base plate 53. Such transport interfaces can be or include, for example, eyelets 100 or the like, which are, for example, firmly attached to the base plate 53 or are screwed into additional threads in the base plate 53 for the purpose of lifting the base plate 53.

[0053] By lifting the functional module 50, the lower ballast plate 20 is exposed so that another ballast plate, for example the upper ballast plate 30 in Figures 1 to 3, can be placed on the lower ballast plate 20 in Figures 1 to 3. The upper ballast plate 30 is again placed in such a way that the through holes 60 are aligned, i.e. the through holes 60 in the upper ballast plate 30 are aligned with the through holes in the lower ballast plate 20, as shown in Figure 8.

[0054] Figure 9 shows the resulting stack comprising the two ballast plates 20 and 30 and the base plate 53 of the functional module 50 after the functional module 50 has been placed on the ballast plate stack.

[0055] Figure 10 shows the completed arrangement after the appropriately long fastening screws 70 have been inserted through the through holes 60 and screwed into the threads 80 in the base structure 12. The length of the fastening screws 70 is preferably adapted to the thickness of the plate stack such that the screw head of the fastening screws 70 can exert a contact force on the base plate 53 and compress the plate stack.

[0056] Figures 11 to 16 show a further exemplary embodiment of a method for producing an arrangement comprising two ballast plates 20 and 30 and a functional module 50 with base plate 53.

[0057] Figure 11 shows the floor structure 12 of the rail vehicle 10 after securing elements in the form of threaded rods 200 have been firmly connected to the floor structure 12 and extend vertically upward from the floor structure 12. The ends of the threaded rods 200 facing the floor structure 12 can be detachably or firmly connected to the floor structure 12, for example, welded to the floor structure 12 or screwed into a respective associated thread 80 in the floor structure 12.

[0058] Figure 12 shows the arrangement after the ballast plate 20 has been placed on the floor structure 12. The ballast plate 20 is placed in place by pushing the through holes 60 of the ballast plate 20 onto the vertically positioned threaded rods 200. Since the threaded rods 200 are longer than the thickness of the lower ballast plate 20, the upper ends of the threaded rods 200 protrude beyond the upper plate level of the ballast plate 20 after the ballast plate 20 has been installed.

[0059] Figure 13 shows the arrangement after the functional module 50 has been placed on the lower ballast plate 20. The base plate 53 of the functional module 50 is placed in place by pushing the through holes 60 of the base plate 53 onto the vertically projecting threaded rods 200. Since the threaded rods 200 are longer than the thickness of the plate stack formed from the lower ballast plate 20 and the base plate 53, the upper ends of the threaded rods 200 protrude beyond the upper plate plane of the base plate 53.

[0060] Figure 14 shows the arrangement after the functional module 50 has been screwed to the threaded rods 200 by means of suitably dimensioned nuts 210 and thus screwed to the ballast plate 20 located underneath and the floor structure 12.

[0061] If, for example, after weighing the rail vehicle 10, it is determined that its weight is too low or the weight distribution of the rail vehicle 10 is not optimal, one or more additional ballast plates, for example the upper ballast plate 30 shown in Figures 1 to 3, can be subsequently installed. During this subsequent installation, the functional module 50 is first lifted and moved away, as shown in Figure 15.

[0062] By moving the functional module 50 away, the lower ballast plate 20 is exposed so that another upper ballast plate 30 can be placed on the lower ballast plate 20. The upper ballast plate 30 is placed by pushing the through holes 60 of the upper ballast plate 30 onto the vertically projecting threaded rods 200, as shown in Figure 16.

[0063] Figure 17 shows the arrangement after the functional module 50 has been placed on the upper ballast plate 30. Since the threaded rods 200 are longer than the thickness of the plate stack formed from the ballast plates 20 and 30 and the base plate 53, the upper ends of the threaded rods 200 protrude beyond the upper plate plane of the base plate 53.

[0064] Figure 18 shows the completed arrangement after, for example, the same fastening nuts 210 as those according to Figure 14 have been screwed to the threaded rods 200 and the functional module 50 has thus been screwed to the ballast plates 20 and 30 located underneath and to the floor structure 12 and is preferably pressed onto them.

[0065] If, after further weighing of the rail vehicle 10, it is determined that its weight lies within a permissible range, the projecting section of the threaded rods can be cut off. Figure 19 shows the resulting arrangement with shortened threaded rods 200.

[0066] Finally, it should be mentioned that the features of all the embodiments described above can be combined with one another in any desired manner to form further alternative embodiments of the invention. All features of subclaims can also be combined individually with each of the subordinate claims, either individually or in any desired combination with one or more other subclaims, to obtain further alternative embodiments.
