[0003] 1 CAB AND COMMERCIAL VEHICLE

[0004] The present invention relates to a driver's cab for a commercial vehicle, in particular for a military commercial vehicle, and to a commercial vehicle, in particular a military commercial vehicle, with such a driver's cab.

[0005] Military vehicles can roll over in difficult terrain. This can exert considerable force on the cab. Furthermore, it is common practice to mount various accessories on the cab roof of military vehicles, such as antennas, machine gun mounts, smoke grenade launchers, or similar equipment. If the vehicle has a continuous windshield, forces from the cab roof must be diverted through the cab frame to prevent the windshield from shattering and being forced into the cab interior, which could compromise the occupants' survival space.

[0006] In the event of a rollover, even greater forces act on the cab roof, cab frame, and windshield of military vehicles with a continuous windshield. This is due to the weight of the additional equipment, but especially to point loads, such as those from a machine gun mount. With a conventional roof design, in a rollover, the additional equipment could push inwards, and parts of the cab roof could intrude into the interior. This would narrow the interior space, and protruding parts could pose a potential danger to the crew.

[0007] It is therefore possible to incorporate reinforcements into the cab frame itself. External roll bars are also possible. However, such roll bars are bulky and must be fitted or installed separately. This RMM24007PWO DPT24009 WO

[0008] Rheinmetall MAN Military Vehicles Austria Ltd.

[0009] Option 2 leads to an increase in the height and width of the military vehicle, thereby impairing, for example, its loading capacity. Reinforcements within the cab frame are complex in the production process and increase material and production costs.

[0010] Against this background, one object of the present invention is to provide an improved driver's cab for a commercial vehicle.

[0011] Accordingly, a driver's cab for a commercial vehicle, in particular for a military commercial vehicle, is proposed. The driver's cab comprises a cab shell enclosing an interior space, a supporting structure that carries the cab shell, and a cab roof structure arranged on the roof of the cab shell and outside the interior space, wherein the cab roof structure is connected to the supporting structure, and wherein an outer skin of the cab roof is arranged between the cab roof structure and the supporting structure.

[0012] Because the cab roof structure is directly connected to the supporting structure, it is reliably prevented that forces are transmitted into the outer skin and thus directly into the cab roof. This reliably prevents deformation of the outer skin into the interior. Excessive mechanical stress on the windshield attached to the cab is also avoided.

[0013] The driver's cab is preferably protected. However, the driver's cab may also be unprotected. In this context, "protected" means, in particular, that the driver's cab is armored. Specifically, in this case, the driver's cab is protected against gunfire, booby traps, improvised explosive devices (IEDs), mines, or the like. The driver's cab may also be designated as RMM24007PWO DPT24009 WO

[0014] Rheinmetall MAN Military Vehicles Austria Ltd.

[0015] 3

[0016] The cab is also referred to as the driver's cabin or driver's cab. It is designed to accommodate a crew, for example, a driver and at least one passenger. The cab can be constructed of armored steel plates or may incorporate armored steel plates. However, aluminum alloys, ceramic composites, and / or fiber composites can also be used.

[0017] The driver's cab is preferably assigned a coordinate system with a longitudinal direction (x-direction), a transverse direction (y-direction), and a vertical direction (z-direction). Accordingly, the term "longitudinal direction" can be replaced by the term "x-direction." The term "transverse direction" can be replaced by the term "y-direction," and the term "z-direction" can be replaced by the term "vertical direction." The directions are oriented perpendicular to each other.

[0018] The cab preferably comprises the cab shell with a cab front wall, a cab rear wall opposite the cab front wall, two cab side walls opposite each other, and a cab floor. The cab roof is positioned opposite the cab floor. The cab roof is part of the cab shell. A windshield may be mounted on the front of the cab. The windshield may be divided into several sections. Doors may be provided on the cab side walls.

[0019] The cab front wall, the cab rear wall, the cab side walls, the cab roof, and the cab floor enclose the cab interior and thus separate it from its surroundings. The interior can be accessed from the surroundings via the doors mentioned above. The cab floor is preferably RMM24007PWO DPT24009 WO

[0020] Rheinmetall MAN Military Vehicles Austria Ltd.

[0021] 4. Multiple arches. In particular, the cab floor can have an egg-shaped or ovoid geometry, at least in sections. The cab floor is specifically optimized for mine protection.

[0022] The supporting structure is part of the cab shell. This structure supports, for example, sheet metal or plates from which the cab side walls, front wall, rear wall, and / or roof are constructed. One of these sheet metal or plates is, for example, the aforementioned outer skin. In this context, "sheet metal" can also refer to, for example, a plate of armored steel. Furthermore, the term "sheet metal" is not limited to metallic materials. Fiber-reinforced composites, such as organosheets, can also be used.

[0023] The supporting structure can be composed of a variety of profile beams. These beams can be rectangular, T-profiles, I-profiles, C-profiles, or similar shapes. The profile beams can be made of steel or aluminum, for example. Fiber-reinforced composites can also be used. A combination of these materials is also possible. The profile beams can run parallel and / or diagonally to the longitudinal and / or transverse direction. They can also run vertically. The supporting structure can be truss-like or skeletal.

[0024] The cab roof assembly is directly connected to the supporting structure, so that forces from the cab roof assembly are transferred into the supporting structure and not directly into the cab roof, especially into the outer skin. The outer skin is positioned between the cab roof assembly and the supporting structure. The cab roof assembly can be accessed through the outer skin RMM24007PWO DPT24009 WO

[0025] Rheinmetall MAN Military Vehicles Austria Ltd.

[0026] 5 must be firmly connected to the supporting structure. A screw connection is preferably used for this purpose.

[0027] According to one embodiment, the cab roof structure is screwed to the supporting structure through the outer skin.

[0028] A variety of fastening elements, such as screws, can be used to connect the cab roof assembly to the supporting structure, particularly by bolting it in place. This allows for a detachable connection between the cab roof assembly and the supporting structure. The cab roof assembly can thus be individually adapted to the specific application of the commercial vehicle. Various different cab roof assemblies can be selected from a modular system and mounted on the cab depending on the specific application of the cab or the commercial vehicle.

[0029] According to another embodiment, the supporting structure has a roof substructure to which the cab roof structure is connected, and a side substructure, wherein the roof substructure is connected to the side substructure.

[0030] The roof substructure primarily supports the outer skin. The roof substructure and the side substructure can be bolted and / or welded together, for example. The roof substructure preferably has a skeletal or truss-like geometry. The roof substructure preferably runs along the transverse and / or longitudinal direction of the cab. The side substructure preferably runs along the vertical direction. RMM24007PWO DPT24009 WO

[0031] Rheinmetall MAN Military Vehicles Austria Ltd.

[0032] 6

[0033] According to another embodiment, the roof support structure has a plurality of roof profile beams extending along and / or diagonally to a longitudinal direction of the cab and / or a transverse direction of the cab.

[0034] The roof profile beams thus form a truss-like structure. The roof profile beams can be bolted and / or welded together. Any steel or aluminum profiles can be used as roof profile beams. Fiber-reinforced composite materials can also be used for the roof profile beams. The cab roof structure is preferably connected to the roof profile beams. Threaded sleeves can be attached to the roof profile beams, into which fasteners, such as screws, can be screwed to connect the cab roof structure to the supporting structure, in particular to the roof substructure.

[0035] According to another embodiment, the side support structure has a plurality of side profile beams running along a vertical direction of the cab.

[0036] The side profile beams can extend down to the cab floor and be firmly connected to it. The forces from the roof substructure are transferred into the side profile beams.

[0037] According to another embodiment, the cab roof structure adjoins a cab front wall of the cab shell.

[0038] In other words, the cab roof structure is positioned directly above the windshield of the cab roof. The fact that the cab roof structure "adjoins" the front wall of the cab means, in this case, in particular, that the cab roof structure, viewed along its length, is not RMM24007PWO DPT24009 WO

[0039] Rheinmetall MAN Military Vehicles Austria Ltd.

[0040] 7 extends beyond the front wall of the cab, but only as far as it reaches.

[0041] According to another embodiment, the cab roof structure extends between a first cab side wall of the cab shell and a second cab side wall of the cab shell.

[0042] Thus, the cab roof structure extends primarily along the transverse direction. In other words, the cab roof structure, viewed along the transverse direction, exhibits its principal direction of extension. The "principal direction of extension" primarily refers to the direction along which the cab roof structure has its greatest geometric extent.

[0043] According to another embodiment, the cab roof structure has a roof structure support structure and a roof structure support plate which is connected to the roof structure support structure, wherein the roof structure support structure is arranged between the outer skin and the roof structure support plate.

[0044] For example, the roof structure support structure and the roof support plate can be welded together. This improves the rigidity of the cab roof structure. However, a bolted connection is also possible. The roof support plate covers the roof structure support structure. The roof structure support structure serves to space the roof support plate from the cab roof, particularly from the outer skin. Specifically, the cab roof structure is connected to the cab's supporting structure by means of the roof structure support structure.

[0045] According to another embodiment, the roof structure support structure has a first roof structure profile beam, a second roof structure profile beam, wherein the first roof structure profile beam and the second roof structure profile beam are parallel RMM24007PWO DPT24009 WO

[0046] Rheinmetall MAN Military Vehicles Austria Ltd.

[0047] 8 are arranged relative to each other and spaced apart from each other, a third roof structure profile beam and a fourth roof structure profile beam are arranged, the third roof structure profile beam and the fourth roof structure profile beam being arranged at an angle to the first roof structure profile beam and at an angle to the second roof structure profile beam and connecting the first roof structure profile beam and the second roof structure profile beam to each other.

[0048] In particular, the first and second roof structure profile beams run along the transverse direction. These beams are spaced apart from each other along their length. The third and fourth roof structure profile beams run diagonally both transversely and longitudinally. They are inclined in opposite directions, forming a V-shaped arrangement. The first, second, third, and fourth roof structure profile beams are preferably welded together, forming a single welded component for the roof structure. The roof structure profile beams can be rectangular tubes, for example. Suitable materials include steel and aluminum.However, fiber composite materials are also possible.

[0049] According to another embodiment, the roof structure support structure has a fifth roof structure profile beam, wherein the fifth roof structure profile beam is angled at each end.

[0050] The fifth roof structure profile beam is preferably not directly connected to the other roof structure profile beams. Rather, the fifth roof structure profile beam is connected to the other roof structure profile beams by means of the roof structure support plate. Alternatively, the fifth roof structure profile beam can be RMM24007PWO DPT24009 WO

[0051] Rheinmetall MAN Military Vehicles Austria Ltd.

[0052] 9. The fifth roof structure profile beam can also be directly connected to the second roof structure profile beam. However, if the fifth roof structure profile beam is not directly connected to the second roof structure profile beam, the production of the roof structure support structure is simplified. The roof structure support structure, together with its roof structure profile beams, forms a skeletal or truss-like structure. The fifth roof structure profile beam preferably has a central section extending along the transverse direction, with the central section being arranged between two end sections that extend obliquely both transversely and longitudinally. The central section and the end sections can be welded together.

[0053] According to another embodiment, the first roof structure profile beam, the second roof structure profile beam, the third roof structure profile beam, the fourth roof structure profile beam and / or the fifth roof structure profile beam each have screw sleeves.

[0054] It is not necessary for each of the roof structure profile beams to have such screw sleeves. The screw sleeves allow the cab roof structure to be connected to the cab's supporting structure, in particular by bolting. The screw sleeves can be welded and / or pressed into the respective roof structure profile beams.

[0055] According to another embodiment, the roof structure support plate has a centrally arranged mounting opening for mounting an effector on the cab roof structure.

[0056] Viewed along the transverse direction, the mounting opening is located in the center of the cab roof. The mounting opening can, for example, be a circular opening. Possible effectors include, for example, a remote-controlled weapon station, a smoke launcher, or a manually operated RMM24007PWO DPT24009 WO.

[0057] Rheinmetall MAN Military Vehicles Austria Ltd.

[0058] 10 machine guns, a manually operated grenade launcher, sensors or the like may be mounted.

[0059] According to another embodiment, the roof support plate has cutouts so that the roof support plate only covers the roof support structure.

[0060] The number of cutouts is arbitrary. Preferably, the cutouts are triangular. However, any other geometry can be chosen. The cutouts allow for a reduction in the weight of the roof support plate. In a top view, the roof support plate then only partially conceals the roof structure and preferably projects only slightly beyond it. Thus, the roof support plate also has a truss-like or skeletal geometry. Furthermore, the roof support plate can have recesses along the roof structure. These recesses can serve as attachment points for additional components, such as spotlights or the like.

[0061] According to another embodiment, the roof structure support structure is guided at least partially around a roof opening provided in the cab roof.

[0062] A roof hatch assembly can be mounted at the roof penetration. The roof structure support structure can be routed around the roof penetration by angling the fifth roof structure profile beam at each end and by having a trailing edge on the roof support plate facing the roof penetration, which is angled, at least in sections, so that the roof support plate extends around the roof penetration.

[0065] Furthermore, a commercial vehicle, in particular a military commercial vehicle, with such a driver's cab is proposed.

[0066] The commercial vehicle can be a truck. In particular, the commercial vehicle is an off-road truck. The commercial vehicle is a multi-axle vehicle. The commercial vehicle can be a two-axle, three-axle, four-axle, or five-axle vehicle. The commercial vehicle preferably includes all-wheel drive. The commercial vehicle can therefore also be referred to as an all-wheel-drive commercial vehicle. The commercial vehicle can be a protected commercial vehicle. The commercial vehicle includes the driver's cab, which is supported by a chassis. Furthermore, the commercial vehicle can have an interchangeable body, which is also supported by the chassis. The commercial vehicle can be armed or unarmed.

[0067] The embodiments and features described for the proposed driver's cab apply accordingly to the proposed commercial vehicle and vice versa.

[0068] The term "one" here should not necessarily be understood as restricting the number to exactly one element. Rather, it can also refer to multiple elements, such as two, three, or more. Similarly, every other counter used here should not be interpreted as restricting the number to the exact number stated. Instead, numerical deviations, both higher and lower, are possible unless otherwise specified.

[0069] Other possible implementations of the driver's cab and / or the commercial vehicle also include combinations of features or embodiments described previously or subsequently with regard to the exemplary embodiments, even if not explicitly mentioned. The person skilled in the art will also recognize individual aspects as RMM24007PWO DPT24009 WO

[0084] In the figures, identical or functionally equivalent elements have been given the same reference symbols, unless otherwise indicated.

[0085] Fig. 1 shows a schematic side view of an embodiment of a commercial vehicle 1.

[0086] Commercial vehicle 1 is a land vehicle. Commercial vehicle 1 is specifically a military commercial vehicle. Commercial vehicle 1 can therefore also be referred to as a military commercial vehicle. Commercial vehicle 1 can be a truck. Specifically, commercial vehicle 1 is an off-road truck. Commercial vehicle 1 can be a protected vehicle. Therefore, commercial vehicle 1 can also be referred to as a protected commercial vehicle.

[0087] The commercial vehicle 1 is assigned a coordinate system with a longitudinal direction (x-direction x), a transverse direction (y-direction y), and a vertical direction (z-direction z). The directions x, y, and z are oriented perpendicular to each other. The z-direction z is oriented parallel to a gravity direction g. The gravity direction g is oriented from top to bottom in the orientation shown in Fig. 1. RMM24007PWO DPT24009 WO

[0088] Rheinmetall MAN Military Vehicles Austria Ltd.

[0089] 14

[0090] Commercial vehicle 1 is a wheeled vehicle. Commercial vehicle 1 comprises a chassis 2 with a plurality of axles 3, 4, 5, 6. Each of the axles 3, 4, 5, 6 is assigned at least one pair of wheels 7, 8, 9, 10. For example, four axles 3, 4, 5, 6 can be provided. This means that commercial vehicle 1 is a four-axle vehicle in this case. However, the number of axles 3, 4, 5, 6 is arbitrary. Commercial vehicle 1 can also be a two-axle, three-axle, or five-axle vehicle. Commercial vehicle 1 preferably includes all-wheel drive. This means that all axles 3, 4, 5, 6 can be driven. Commercial vehicle 1 can therefore also be referred to as an all-wheel-drive commercial vehicle. At least one of the axles 3, 4, 5, 6 is steerable. Preferably, two front axles or front axles 3 and 4 are steerable. Alternatively, all axles 3, 4, 5, and 6 can be steerable.

[0091] The chassis 2 carries a cab 11 of the commercial vehicle 1. The cab 11 can also be referred to as the driver's cab or driver's cabin. The cab 11 is preferably protected against gunfire, booby traps, improvised explosive devices (IEDs), mines, or the like. The cab 11 encloses an interior space 12 in which a crew of the commercial vehicle 1, for example, a driver and one or two passengers, can be located. The cab 11 encloses the interior space 12 and thus separates it from the surrounding area 13. The interior space 12 is accessible from the surrounding area 13 by means of openable doors 14.

[0092] The chassis 2 is suitable for carrying an interchangeable body 15 of the commercial vehicle 1 in addition to the driver's cab 11. The body 15 can be, for example, a flatbed, a container, a box body, a tank, or the like. Figure 1 shows a body 15 in the form of a container. RMM24007PWO DPT24009 WO

[0093] Rheinmetall MAN Military Vehicles Austria Ltd.

[0094] 15

[0095] The commercial vehicle 1 can move along a surface 17 in a direction of travel 16 using its wheels 7, 8, 9, 10. The direction of travel 16 is oriented opposite to the x-direction x. However, this does not preclude the commercial vehicle 1 from moving in the opposite direction of travel 16 on the surface 17 – for example, in reverse. The surface 17 can be a road or any type of terrain.

[0096] Fig. 2 shows a schematic front view of an embodiment of a driver's cab 11 as previously mentioned for the commercial vehicle 1.

[0097] The aforementioned coordinate system with directions x, y, z can also be assigned to the cab 11. The cab 11 comprises a mine-protected, in particular mine-protection-optimized, cab floor 18 and a cab shell 19, which is firmly connected to the cab floor 18. The cab floor 18 is, in particular, part of the cab shell 19. The cab shell 19 has a cab roof 20 arranged opposite the cab floor 18, two cab side walls 21, 22 arranged opposite each other, in particular a first cab side wall 21 and a second cab side wall 22, which may be equipped with doors 14 as mentioned above, a cab front wall 23, and a cab rear wall (not shown) arranged opposite the cab front wall 23. The cab front wall 23 may have a windshield 24. The windshield 24 can be divided into two windshield sections 25, 26.However, the windshield 24 can also be a single piece.

[0098] The cab floor 18 and the cab shell 19 enclose the interior 12. The interior 12 can be accessed from the surroundings 13 by means of the aforementioned doors 14 and / or hatches (not shown). A first seat 27, a second seat 28, and a third seat 29 are accommodated in the cab 11 and thus located within the interior 12. The RMM24007PWO DPT24009 WO

[0099] Rheinmetall MAN Military Vehicles Austria Ltd.

[0100] 16. The first seat 27 can also be called the driver's seat. The second seat 28 can also be called the passenger seat. The third seat 29 can also be called the middle seat, since the third seat 29 is positioned midway between seats 27 and 28 when viewed along the y-direction y.

[0101] Seats 27, 28, and 29 are positioned side-by-side and spaced apart along the y-direction y. The third seat, 29, is positioned above the first seat, 27, and the second seat, 28, along the z-direction z. The third seat, 29, can also be positioned centrally within the driver's cab 11 when viewed along the y-direction y. Seats 27, 28, and 29 are separate components and can be individually replaced. Therefore, seats 27, 28, and 29 do not form a continuous bench seat.

[0102] Fig. 3 shows a schematic perspective view of an embodiment of a cab roof 20 as previously mentioned. Fig. 4 shows another schematic perspective view of the cab roof 20. Fig. 5 shows a schematic perspective partial sectional view of the cab roof 20. Reference is made to Figs. 3 to 5 concurrently below.

[0103] The cab roof 20 is part of the cab shell 19. The cab shell 19 has a supporting structure 30, only partially shown in Figures 4 and 5, which supports the cab shell 19. The supporting structure 30 comprises a roof substructure 31, which has a plurality of roof profile beams 32, 33, 34 (Figure 5) extending along and / or obliquely to the x-direction x and / or the y-direction y, of which only three are labeled with a reference numeral in Figure 5.

[0104] In addition to the roof support structure 31, the support structure 30 has a side support structure 35 (Fig. 4). The side support structure 35 and the roof support structure 31 together form the support structure 30. The side support structure 35 can, for example, be part of the cab side walls 21, 22. The RMM24007PWO DPT24009 WO

[0105] Rheinmetall MAN Military Vehicles Austria Ltd.

[0106] 17 The roof support structure 31 is connected to the side support structure 35. The side support structure 35 comprises a plurality of side profile beams 36, 37, 38, 39 extending along the z-direction, of which only four are provided with a reference numeral in Fig. 4.

[0107] The cab roof 20 further comprises an outer skin 40, which is supported by the supporting structure 30. The outer skin 40 can be a steel sheet or plate, in particular an armored steel plate. The outer skin 40 can also be an aluminum sheet or plate. Fiber composite materials can also be used for the outer skin 40. The outer skin 40 can be composed of several sub-components, which are, for example, welded together. The outer skin 40 has an outer surface 41, which faces the environment 13 and away from the interior 12, and an inner surface 42, which faces the interior 12 and away from the environment 13. The inner surface 42 thus faces the supporting structure 30.

[0108] A roof opening 43 is provided in the cab roof 20, particularly in the outer skin 40. The roof opening 43 penetrates the cab roof 20. The roof opening 43 is specifically designed as a cutout or opening that connects the interior 12 with the surroundings 13. A roof hatch assembly (not shown) can be mounted on the roof opening 43.

[0109] A cab roof structure 44 is mounted on the outside of the cab roof 20. The cab roof structure 44 is located outside the interior 12 and thus in the surrounding area 13. The cab roof structure 44 is connected to the supporting structure 30. In particular, the cab roof structure 44 is connected to the roof substructure 31 and especially to at least a portion of the roof profile beams 32, 33, 34. The outer skin 40 is located between the cab roof structure 44 and the supporting structure 30. RMM24007PWO DPT24009 WO

[0110] Rheinmetall MAN Military Vehicles Austria Ltd.

[0111] 18

[0112] The cab roof assembly 44 can be connected to the supporting structure 30 through the outer skin 40, in particular by bolting. The cab roof assembly 44 is arranged such that it abuts the front wall 23 of the cab shell 19. The cab roof assembly 44 extends along the y-direction y between the first cab side wall 21 and the second cab side wall 22.

[0113] Fig. 6 shows a schematic perspective view of an embodiment of a cab roof structure 44 as previously mentioned. Fig. 7 shows another schematic perspective view of the cab roof structure 44. Fig. 8 shows a schematic perspective view of an embodiment of a roof structure support structure 45 for the cab roof structure 44. Fig. 9 shows a schematic perspective view of an embodiment of a roof structure support plate 46 for the cab roof structure 44. Reference is made to Figs. 6 to 9 concurrently below.

[0114] The roof support plate 46 is rigidly connected to the roof support structure 45. This connection can be made using screws. Alternatively, the roof support plate 46 and the roof support structure 45 can be welded together. This improves the rigidity of the cab roof structure 44. Specifically, the roof support structure 45 is located between the outer skin 40 and the roof support plate 46.

[0115] As shown in Fig. 8, the roof structure support structure 45 has a first roof structure profile beam 47 extending along the y-direction y. Furthermore, the roof structure support structure 45 has a second roof structure profile beam 48, which also extends along the y-direction y. Thus, the first roof structure profile beam 47 and the second roof structure profile beam 48 are arranged parallel to each other and spaced apart from each other along the x-direction x. RMM24007PWO DPT24009 WO

[0116] Rheinmetall MAN Military Vehicles Austria Ltd.

[0117] 19

[0118] Furthermore, the roof structure support structure 45 includes a third roof structure profile beam 49 and a fourth roof structure profile beam 50. The third roof structure profile beam 49 and the fourth roof structure profile beam 50 are arranged at an angle to the first roof structure profile beam 47 and at an angle to the second roof structure profile beam 48, and connect the first roof structure profile beam 47 to the second roof structure profile beam 48. For example, the third roof structure profile beam 49 and the fourth roof structure profile beam 50 are welded to the first roof structure profile beam 47 and the second roof structure profile beam 48. The third roof structure profile beam 49 and the fourth roof structure profile beam 50 are arranged at opposite angles, so that the third roof structure profile beam 49 and the fourth roof structure profile beam 50 form a V-shaped geometry.

[0119] The roof structure support structure 45 further comprises a fifth roof structure profile beam 51, which is not directly connected to any of the roof structure profile beams 47, 48, 49, 50. Rather, the fifth roof structure profile beam 51 is indirectly connected to the first roof structure profile beam 47 and the second roof structure profile beam 48 by means of the roof structure support plate 46. The fifth roof structure profile beam 51 has a central section 52 extending along the y-direction y and two end sections 53, 54, which are arranged at an angle to the central section 52. For example, the end sections 53, 54 are welded to the central section 52.

[0120] The roof structure profile beams 47, 48, 49, and 50 are welded together, so that the roof structure support structure 45 forms a welded structure or welded component. However, the fifth roof structure profile beam 51, as mentioned previously, is not directly connected to the roof structure profile beams 47, 48, 49, and 50. The roof structure profile beams 47, 48, 49, 50, and 51 can, for example, be rectangular profiles. For example, the roof structure profile beams 47, 48, 49, 50, and 51 are steel tubes or aluminum tubes. However, fiber composite materials can also be used for the RMM24007PWO DPT24009 WO.

[0123] Roof structure profile beams 47, 48, 49, 50, 51 are used. An adhesive bond can then be used to connect the roof structure profile beams 47, 48, 49, 50. The roof structure support structure 45 is truss-like or skeletal.

[0124] Each of the roof structure profile beams 47, 48, 49, 50, 51 can have a plurality of screw sleeves 55, 56, of which only two are indicated with a reference numeral in Fig. 8. The screw sleeves 55, 56 can be pressed and / or welded into the roof structure profile beams 47, 48, 49, 50, 51. In the roof structure support structure 45 shown in Fig. 8, only the roof structure profile beams 47, 48, 51 have such screw sleeves 55, 56. However, the roof structure profile beams 49, 50 can also have such screw sleeves 55, 56.

[0125] As shown in Fig. 9, the roof support plate 46 has a centrally located mounting opening 57 along the y-direction. The mounting opening 57 can, for example, be a circular opening that penetrates the roof support plate 46. An effector can be mounted to the driver's cab roof structure 44 at the mounting opening 57. In this context, an "effector" can be, for example, a remotely controlled weapon station, a manually operated machine gun, a manually operated grenade launcher, sensors, or the like.

[0126] Furthermore, the roof support plate 46 comprises a plurality of cutouts 58, 59, 60, 61, 62, 63. The cutouts 58, 59, 60, 61, 62, 63 can be triangular. The cutouts 58, 59, 60, 61, 62, 63 are arranged such that, in a top view, the roof support plate 46 only covers the roof support structure 45. The roof support plate 46 thus has a truss-like structure, like the roof support structure 45. In particular, the roof support plate 46 can be designed in a skeletal form. The roof support plate 46 preferably has recesses in the form of RMM24007PWO DPT24009 WO

[0127] Rheinmetall MAN Military Vehicles Austria Ltd.

[0128] 21 elongated holes, on which, for example, headlights, camouflage nets or the like can be arranged.

[0129] The roof support plate 46 has a straight leading edge 64 extending along the y-direction y. The leading edge 64 can abut the front wall 23 of the driver's cab. Away from the leading edge 64, the roof support plate 46 has a trailing edge 65, which, however, is not straight but runs at least partially at an angle to the y-direction y and the x-direction x. This makes it possible to guide the roof support plate 46, and thus also the roof support structure 45, at least partially around the roof opening 43 provided in the driver's cab roof 20.

[0130] Returning to Fig. 5, it can be seen how the cab roof structure 44 is bolted to the roof substructure 31 by means of fastening elements 66, 67, for example in the form of screws, of which only two are labeled in Fig. 5. The fastening elements 66, 67 pass through the outer skin 40. Specifically, the fastening elements 66, 67 are screwed into the roof profile supports 32, 34 through the threaded sleeves 55, 56. Threaded sleeves 68, 69 are attached to the roof profile supports 32, 34 for this purpose. The threaded sleeves 68, 69 may be welded into the roof profile supports 32, 34. The threaded sleeves 68, 69 protrude through the outer skin 40. The outer skin 40 may have corresponding openings for the threaded sleeves 68, 69.

[0131] Although the present invention has been described using exemplary embodiments, it can be modified in many ways. RMM24007PWO DPT24009 WO
