Description Carriage body part The invention relates to a carriage body part, in particular a rail vehicle carriage body part, in the form of an extruded part with at least one fastening portion which is suitable for fastening an item of equipment and extends in the extrusion direction of the extruded part.
In the area of fastening surfaces, in particular screwed surfaces, of carriage body parts and the items of equipment to be fastened on the carriage body parts there are always certain manufacturing-related deviations with regard to flatness and parallelism, the size of which depends on the respective manufacturing tolerances. In the case of carriage bodies produced from extruded sections made of aluminum, in the case of integrally molded fastening rails deviations predominantly occur in the inclination about the vehicle axis. As a result of said inclinations occurring in a manufacturing-related manner, the screwed surfaces of the fastening rails, after screw connection to an item of equipment mounted thereon, can possibly not be located in a planar manner on the screwed surfaces of the item of equipment such that a wedge-shaped gap remains. These types of wedge-shaped gaps are closed nowadays by means of wedge-shaped spacers or are compensated for by elastic connecting elements (for example screw-connected rubber bearings).
The object underlying the invention is to provide a carriage body part where the abovementioned wedge formation when mounting an item of equipment on the carriage body part does not occur at all, at least less than nowadays in the case of carriage bodies of the prior art.

PCT/EP2013/072390 - 8a -Figure 1 shows a carriage body part 10 of a rail vehicle 20 (not shown in any detail) as well as an = CA 02892337 2015-05-22 item of equipment 30 which preferably includes a converter, a transformer, an air conditioning component or a current collector. The item of equipment 30 comprises fastening elements 40, the bottom surfaces of which in figure 1 forming fastening surfaces 45 for fastening the item of equipment 30 on the carriage body part 10.
The carriage body part 10 is an extruded part 11 which is provided with two extruded fastening rails 50 and 60 which are component parts of the extruded part 11 or are integrally molded in one piece on said extruded part during extrusion molding and have been extruded at the same time in one part with said extruded part and consequently extend in each case along the extrusion direction (or the longitudinal extrusion direction) of the extruded part. As an alternative to this, the carriage body part 10 can be formed by two or more interconnected (e.g. welded) extruded parts, one of the two extruded fastening rails being realized on one of the extruded parts and the other of the two extruded fastening rails being realized on another extruded part.
In the case of the representation according to figure 1, the extrusion direction of the extruded part extends perpendicular to the image plane of figure 1; accordingly, the two fastening rails 50 and 60 also extend perpendicular to the representation plane of figure 1.
Each of the two fastening rails 50 and 60 in the case of the exemplary embodiment according to figure 1 comprise in each case a rectangular cross section which is formed or delimited by an upper fastening surface 70, a support wall 71 which is arranged inside with reference to the vehicle center of the rail vehicle 20 and perpendicular to the fastening surface 70, a support wall 72 which is arranged outside with reference to the vehicle center of the rail vehicle 20 and perpendicular to the fastening surface 70 as well as a carrier portion 73 of the , . CA 02892337 2015-05-22 , PCT/E22013/072390 - 9a -extruded part which holds the support walls. The fastening surface 70 is , = = CA 02892337 2015-05-22 preferably arranged horizontally, and the two support walls 71 and 72 are preferably arranged vertically.
For mounting the item of equipment 30 on the carriage body part 10, the two fastening surfaces 45 of the two fastening elements 40 are fitted onto the fastening surfaces 70 of the two fastening rails 50 and 60. The fastening elements 40 are then fixed on the two fastening rails 50 and 60, for example screw-connected.
Figure 2 shows the fastening element 40, on the right in figure 1, of the item of equipment as well as the fastening rail 60, on the right in figure 1, of the carriage body part in more detail. The broken lines indicate that the fastening surface 45 of the fastening element 40 and the upper fastening surface 70 of the fastening rail 60 are not always parallel to one another and can be angled in a various manner. The various inclinations of the fastening surface 45 and of the fastening surface 70 are indicated in figure 2 by the references +nG, -nG, 4-nRB and -nRB.
Over and above this, figure 2 shows two force vectors Fl and F2 which are necessary in order to press the two fastening surfaces 45 and 70 onto one another. In dependence on the rigidity of the fastening surface 45 and the rigidity of the fastening surface 70, it is possible that the two fastening surfaces, during the assembly operation, that is for example during screw-connecting, cannot be aligned with respect to one another in such a manner that they actually abut in an entirely parallel manner.
In order to ensure or to simplify placing the two fastening surfaces 45 and 70 in a planar manner after mounting, in the case of the carriage body parts according to figures 1 to 13 the fastening rails are weakened locally such that the fastening surface 70 is able to yield when the item of equipment is fastened, in particular when the item of equipment . . .
PCT/EP2013/072390 - 10a -is screw-connected, and is able to be adapted to the alignment of the fastening . , CA 02892337 2015-05-22 surface 45. Exemplary embodiments of local weakening of the fastening rails of the carriage body part are explained in more detail below in conjunction with figures 3 to 13.
Figure 3 shows a three-dimensional representation obliquely from the side of an exemplary embodiment of a carriage body part 10 where the fastening rail 60 (cf. figure 1) is formed by an extruded part 11 and is weakened locally as a result of holes 100, as a result of which it is made flexible in the region of the fastening portions 110 which are provided for fastening the item of equipment 30 or other items of equipment.
The holes 100 are arranged one behind another in the extrusion direction S of the extruded part 11 and result at said places in a flexibility or weakening of the fastening rail 60 wherever an item of equipment is subsequently to be mounted.
In the case of the exemplary embodiment according to figure 3, the holes 100 are arranged in the outside support wall 72 of the fastening rail 60. An arrangement of the holes 100 in the outside support wall is deemed as advantageous compared to an arrangement of the holes 100 on the inside support wall 71 in order to make it easier to adapt the upper fastening surface 70 to the fastening element 40 of the item of equipment 30. As an alternative to this or in addition to it, however, an arrangement of holes on the inner support wall would also be possible.
Figure 3 just shows one of the two fastening rails of the extruded part 11. The statements in conjunction with the arrangement and development of the holes 100 in the case of the fastening rail 60 apply correspondingly to the fastening rail 50 according to figure 1. Local weakening as a result of holes, preferably on the outside support wall 72, is also performed in the case of the fastening rail 50 on the left in figure 1.
CA 02892337 2015-05-22 , Figures 4 to 7 show different embodiments of the holes 100 which can be introduced for local weakening of the fastening rails 50 and 60 according to figure 1 in the outer and/or inner support wall 71 or 72. The size and the contour of the holes 100 are preferably chosen in such a manner that sufficient flexibility of the fastening portions 110 (cf. figure 3) is achieved, but nevertheless sufficient carrying capacity for carrying the respective load is maintained.
Figure 8 shows a second exemplary embodiment of a carriage body part 10 which is formed by an extruded part 11 and on which is mounted an item of equipment 30. It can be seen that the fastening rail 60 is not only weakened locally in the region of the outer support wall 72 as a result of holes 100 in order to achieve a desired flexibility in the region of the fastening portions 110, but over and above this also in the region between the fastening portions 110. Thus, it can be seen in figure 8 that the extruded fastening rail 70 has been completely removed at places 120, 121, and 122. The flexible fastening portions 110 of the fastening rail 60 are consequently separate from one another, as a result of which the flexibility of the fastening portions 110 is increased.
Apart from this, the statements in conjunction with figure 3 apply correspondingly to the embodiment according to figure 8.
Figure 9 shows a further exemplary embodiment of a carriage body part 10 on which an item of equipment 30 is mounted. It can be seen that the fastening rail 60 of the carriage body part 10 is not only weakened locally as a result of places 120, 121 and 122 which are located one behind another along the extrusion direction, but over and above this also as a result of holes 200 which are arranged in the outside support wall 72 of the fastening rail 60 and extend into the region of the upper fastening surface 70. It can be seen that in the region of the fastening portions 110 the upper fastening surface 70 of the fastening rail 60 is reduced as a result of the intrusion of the holes 200.
As a result of the realization of the holes 200, which extend from the outer support wall 72 into the region of the upper fastening surface 70 of the fastening rail 60, as well as over and above this as a result of the places 120, 121 and 122 which are arranged along the extrusion direction S one behind another and in which the material of the fastening rail 60 is completely removed, efficient material weakening is achieved, as a result of which a particularly high degree of flexibility is ensured in the region of the fastening portions 110.
Figure 10 shows a more detailed cross sectional representation of the fastening rail 60 in the region of the recess 200. It can be seen that the cross section of the fastening rail 60 comprises a closed rectangular contour which has been opened locally as a result of a hole 200. In the region of the hole 200, the outer support wall 72 of the fastening rail 60 is completely removed. Over and above this, the hole 200 protrudes into the region of the upper fastening surface 70.
The inner support wall 71 of the fastening rail 60 preferably does not comprise any holes such that it is able to apply the supporting force necessary for carrying the item of equipment to be fastened on the fastening rail 60.
Figure 10 shows over and above this a fastening hole 210 which can serve for screw-connecting the item of equipment to be fastened and not shown in figure 10.
Figure 11 shows a top view of the fastening rail 60 of the carriage body part 10 according to figures 9 and 10. It is possible to see the flexible fastening portion 110 which has been made flexible as a result of the hole 200. It can be seen that the width of the hole 200 along the extrusion direction S
, . CA 02892337 2015-05-22 p , PCT/EP2013/072390 - 13a -is greater than the fastening portion 110 which is imagined or provided for fastening an item of equipment.
* CA 02892337 2015-05-22 As a result of the choice of the size of the hole 200 or as a result of the depth d at which the hole 200 extends into the region of the upper fastening surface 70, the flexibility of the fastening portion 110 is able to be adjusted in a targeted manner.
Figure 12 shows a variant of a weakening of the fastening portion 110. It can be seen that, when viewed in the extrusion direction S, recesses or holes 300, which have been introduced either only in the fastening surface 70 or in addition to the fastening surface 70 also in one of the two support walls, preferably the outer support wall, have been provided upstream and downstream of the fastening portion 110. As a result of the holes 300, the fastening portion 110 becomes flexible without itself communicating directly with one of the holes.
Figure 13 shows a further exemplary embodiment of a carriage body part 10 which is formed as a result of an extruded part 11 which is extruded along the extrusion direction S. It can be seen that the extruded part 11 comprises an extruded fastening rail 400 with an open section (section is open at least in portions), for example an L-section. The section of the fastening rail 400 can be produced within the framework of the extrusion process as an open section; as an alternative to this, the section of the fastening rail 400 can be produced within the framework of the extrusion process as a closed section and only opened in a local or continuous manner as a result of reworking. The fastening rail 400 is completely removed locally at the places 120, 121 and 122 which are located one behind another along the extrusion direction S such that the upper fastening surface 410 is flexible or yielding and can be easily adapted to the alignment of a fastening element 40 of an item of equipment 30 which is to be mounted on the fastening rail 400. The fastening portions, which are formed by the upper fastening surface of the fastening rail . . CA 02892337 2015-05-22 r .
PCT/EP2013/072390 - 14a -400, are marked in figure 13 by way of the reference 420. A
fastening element of an =

item of equipment 30 is mounted on the rear fastening portion 420 in figure 13.
The above exemplary embodiments can comprise one or several of the following features depending on the development:
- the carcass-side fastening rail of the carriage body part is machined such that the outside vertical web (support wall 72 in figures 1 and 3) of the fastening rail is omitted completely or at least in part in the region of the fastening portion or screwed surface.
- The inner vertical web of the fastening rail directly transmits the vertical weight because it communicates with the horizontal bearing surface and is covered at least in part by said bearing surface.
The horizontal bearing surface serves as a screwed surface and transmits longitudinal and transverse forces.
- As a result of weakening the fastening rail, the fastening rail becomes more flexible for torsion about the longitudinal axis of the fastening rail and about the axis of the extruding direction of the extruded section without losing strength at the relevant carrying places.
- Where the design of the rigidity of the item of equipment, the fastening of the item of equipment and development of the fastening rail is coordinated, the fastening portions or the screwed surfaces can be moved to the desired abutment under the preload force.
Although the invention has been illustrated and described in more detail by the preferred exemplary embodiments, the invention is not restricted by the disclosed examples and other variations can be derived therefrom by the expert without departing from the scope of protection of the invention.

PCT/EP2013/072390 - 8a -Figure 1 shows a carriage body part 10 of a rail vehicle 20 (not shown in any detail) as well as an = CA 02892337 2015-05-22 item of equipment 30 which preferably includes a converter, a transformer, an air conditioning component or a current collector. The item of equipment 30 comprises fastening elements 40, the bottom surfaces of which in figure 1 forming fastening surfaces 45 for fastening the item of equipment 30 on the carriage body part 10.
The carriage body part 10 is an extruded part 11 which is provided with two extruded fastening rails 50 and 60 which are component parts of the extruded part 11 or are integrally molded in one piece on said extruded part during extrusion molding and have been extruded at the same time in one part with said extruded part and consequently extend in each case along the extrusion direction (or the longitudinal extrusion direction) of the extruded part. As an alternative to this, the carriage body part 10 can be formed by two or more interconnected (e.g. welded) extruded parts, one of the two extruded fastening rails being realized on one of the extruded parts and the other of the two extruded fastening rails being realized on another extruded part.
In the case of the representation according to figure 1, the extrusion direction of the extruded part extends perpendicular to the image plane of figure 1; accordingly, the two fastening rails 50 and 60 also extend perpendicular to the representation plane of figure 1.
Each of the two fastening rails 50 and 60 in the case of the exemplary embodiment according to figure 1 comprise in each case a rectangular cross section which is formed or delimited by an upper fastening surface 70, a support wall 71 which is arranged inside with reference to the vehicle center of the rail vehicle 20 and perpendicular to the fastening surface 70, a support wall 72 which is arranged outside with reference to the vehicle center of the rail vehicle 20 and perpendicular to the fastening surface 70 as well as a carrier portion 73 of the , . CA 02892337 2015-05-22 , PCT/E22013/072390 - 9a -extruded part which holds the support walls. The fastening surface 70 is , = = CA 02892337 2015-05-22 preferably arranged horizontally, and the two support walls 71 and 72 are preferably arranged vertically.
For mounting the item of equipment 30 on the carriage body part 10, the two fastening surfaces 45 of the two fastening elements 40 are fitted onto the fastening surfaces 70 of the two fastening rails 50 and 60. The fastening elements 40 are then fixed on the two fastening rails 50 and 60, for example screw-connected.
Figure 2 shows the fastening element 40, on the right in figure 1, of the item of equipment as well as the fastening rail 60, on the right in figure 1, of the carriage body part in more detail. The broken lines indicate that the fastening surface 45 of the fastening element 40 and the upper fastening surface 70 of the fastening rail 60 are not always parallel to one another and can be angled in a various manner. The various inclinations of the fastening surface 45 and of the fastening surface 70 are indicated in figure 2 by the references +nG, -nG, 4-nRB and -nRB.
Over and above this, figure 2 shows two force vectors Fl and F2 which are necessary in order to press the two fastening surfaces 45 and 70 onto one another. In dependence on the rigidity of the fastening surface 45 and the rigidity of the fastening surface 70, it is possible that the two fastening surfaces, during the assembly operation, that is for example during screw-connecting, cannot be aligned with respect to one another in such a manner that they actually abut in an entirely parallel manner.
In order to ensure or to simplify placing the two fastening surfaces 45 and 70 in a planar manner after mounting, in the case of the carriage body parts according to figures 1 to 13 the fastening rails are weakened locally such that the fastening surface 70 is able to yield when the item of equipment is fastened, in particular when the item of equipment . . .
PCT/EP2013/072390 - 10a -is screw-connected, and is able to be adapted to the alignment of the fastening . , CA 02892337 2015-05-22 surface 45. Exemplary embodiments of local weakening of the fastening rails of the carriage body part are explained in more detail below in conjunction with figures 3 to 13.
Figure 3 shows a three-dimensional representation obliquely from the side of an exemplary embodiment of a carriage body part 10 where the fastening rail 60 (cf. figure 1) is formed by an extruded part 11 and is weakened locally as a result of holes 100, as a result of which it is made flexible in the region of the fastening portions 110 which are provided for fastening the item of equipment 30 or other items of equipment.
The holes 100 are arranged one behind another in the extrusion direction S of the extruded part 11 and result at said places in a flexibility or weakening of the fastening rail 60 wherever an item of equipment is subsequently to be mounted.
In the case of the exemplary embodiment according to figure 3, the holes 100 are arranged in the outside support wall 72 of the fastening rail 60. An arrangement of the holes 100 in the outside support wall is deemed as advantageous compared to an arrangement of the holes 100 on the inside support wall 71 in order to make it easier to adapt the upper fastening surface 70 to the fastening element 40 of the item of equipment 30. As an alternative to this or in addition to it, however, an arrangement of holes on the inner support wall would also be possible.
Figure 3 just shows one of the two fastening rails of the extruded part 11. The statements in conjunction with the arrangement and development of the holes 100 in the case of the fastening rail 60 apply correspondingly to the fastening rail 50 according to figure 1. Local weakening as a result of holes, preferably on the outside support wall 72, is also performed in the case of the fastening rail 50 on the left in figure 1.
CA 02892337 2015-05-22 , Figures 4 to 7 show different embodiments of the holes 100 which can be introduced for local weakening of the fastening rails 50 and 60 according to figure 1 in the outer and/or inner support wall 71 or 72. The size and the contour of the holes 100 are preferably chosen in such a manner that sufficient flexibility of the fastening portions 110 (cf. figure 3) is achieved, but nevertheless sufficient carrying capacity for carrying the respective load is maintained.
Figure 8 shows a second exemplary embodiment of a carriage body part 10 which is formed by an extruded part 11 and on which is mounted an item of equipment 30. It can be seen that the fastening rail 60 is not only weakened locally in the region of the outer support wall 72 as a result of holes 100 in order to achieve a desired flexibility in the region of the fastening portions 110, but over and above this also in the region between the fastening portions 110. Thus, it can be seen in figure 8 that the extruded fastening rail 70 has been completely removed at places 120, 121, and 122. The flexible fastening portions 110 of the fastening rail 60 are consequently separate from one another, as a result of which the flexibility of the fastening portions 110 is increased.
Apart from this, the statements in conjunction with figure 3 apply correspondingly to the embodiment according to figure 8.
Figure 9 shows a further exemplary embodiment of a carriage body part 10 on which an item of equipment 30 is mounted. It can be seen that the fastening rail 60 of the carriage body part 10 is not only weakened locally as a result of places 120, 121 and 122 which are located one behind another along the extrusion direction, but over and above this also as a result of holes 200 which are arranged in the outside support wall 72 of the fastening rail 60 and extend into the region of the upper fastening surface 70. It can be seen that in the region of the fastening portions 110 the upper fastening surface 70 of the fastening rail 60 is reduced as a result of the intrusion of the holes 200.
As a result of the realization of the holes 200, which extend from the outer support wall 72 into the region of the upper fastening surface 70 of the fastening rail 60, as well as over and above this as a result of the places 120, 121 and 122 which are arranged along the extrusion direction S one behind another and in which the material of the fastening rail 60 is completely removed, efficient material weakening is achieved, as a result of which a particularly high degree of flexibility is ensured in the region of the fastening portions 110.
Figure 10 shows a more detailed cross sectional representation of the fastening rail 60 in the region of the recess 200. It can be seen that the cross section of the fastening rail 60 comprises a closed rectangular contour which has been opened locally as a result of a hole 200. In the region of the hole 200, the outer support wall 72 of the fastening rail 60 is completely removed. Over and above this, the hole 200 protrudes into the region of the upper fastening surface 70.
The inner support wall 71 of the fastening rail 60 preferably does not comprise any holes such that it is able to apply the supporting force necessary for carrying the item of equipment to be fastened on the fastening rail 60.
Figure 10 shows over and above this a fastening hole 210 which can serve for screw-connecting the item of equipment to be fastened and not shown in figure 10.
Figure 11 shows a top view of the fastening rail 60 of the carriage body part 10 according to figures 9 and 10. It is possible to see the flexible fastening portion 110 which has been made flexible as a result of the hole 200. It can be seen that the width of the hole 200 along the extrusion direction S
, . CA 02892337 2015-05-22 p , PCT/EP2013/072390 - 13a -is greater than the fastening portion 110 which is imagined or provided for fastening an item of equipment.
* CA 02892337 2015-05-22 As a result of the choice of the size of the hole 200 or as a result of the depth d at which the hole 200 extends into the region of the upper fastening surface 70, the flexibility of the fastening portion 110 is able to be adjusted in a targeted manner.
Figure 12 shows a variant of a weakening of the fastening portion 110. It can be seen that, when viewed in the extrusion direction S, recesses or holes 300, which have been introduced either only in the fastening surface 70 or in addition to the fastening surface 70 also in one of the two support walls, preferably the outer support wall, have been provided upstream and downstream of the fastening portion 110. As a result of the holes 300, the fastening portion 110 becomes flexible without itself communicating directly with one of the holes.
Figure 13 shows a further exemplary embodiment of a carriage body part 10 which is formed as a result of an extruded part 11 which is extruded along the extrusion direction S. It can be seen that the extruded part 11 comprises an extruded fastening rail 400 with an open section (section is open at least in portions), for example an L-section. The section of the fastening rail 400 can be produced within the framework of the extrusion process as an open section; as an alternative to this, the section of the fastening rail 400 can be produced within the framework of the extrusion process as a closed section and only opened in a local or continuous manner as a result of reworking. The fastening rail 400 is completely removed locally at the places 120, 121 and 122 which are located one behind another along the extrusion direction S such that the upper fastening surface 410 is flexible or yielding and can be easily adapted to the alignment of a fastening element 40 of an item of equipment 30 which is to be mounted on the fastening rail 400. The fastening portions, which are formed by the upper fastening surface of the fastening rail . . CA 02892337 2015-05-22 r .
PCT/EP2013/072390 - 14a -400, are marked in figure 13 by way of the reference 420. A
fastening element of an =
=
item of equipment 30 is mounted on the rear fastening portion 420 in figure 13.
The above exemplary embodiments can comprise one or several of the following features depending on the development:
- the carcass-side fastening rail of the carriage body part is machined such that the outside vertical web (support wall 72 in figures 1 and 3) of the fastening rail is omitted completely or at least in part in the region of the fastening portion or screwed surface.
- The inner vertical web of the fastening rail directly transmits the vertical weight because it communicates with the horizontal bearing surface and is covered at least in part by said bearing surface.
The horizontal bearing surface serves as a screwed surface and transmits longitudinal and transverse forces.
- As a result of weakening the fastening rail, the fastening rail becomes more flexible for torsion about the longitudinal axis of the fastening rail and about the axis of the extruding direction of the extruded section without losing strength at the relevant carrying places.
- Where the design of the rigidity of the item of equipment, the fastening of the item of equipment and development of the fastening rail is coordinated, the fastening portions or the screwed surfaces can be moved to the desired abutment under the preload force.
Although the invention has been illustrated and described in more detail by the preferred exemplary embodiments, the invention is not restricted by the disclosed examples and other variations can be derived therefrom by the expert without departing from the scope of protection of the invention.
