Description

[0001] The present invention relates to a commercial vehicle, in particular a military commercial vehicle.

[0002] A driver's cab for a commercial vehicle, especially a military vehicle, must meet various requirements. Firstly, ergonomics, safety, mine protection, and functionality are essential. Secondly, the cab must be capable of being replaced or modified within a specific timeframe. In conventional cab designs, pneumatic, hydraulic, and / or electrical connections and cables are routed through the front wall and often bonded to it. This results in significant labor and time expenditure when modifying or replacing the cab.

[0003] Against this background, one object of the present invention is to provide an improved commercial vehicle.

[0004] Accordingly, a utility vehicle, in particular a military utility vehicle, is proposed. The utility vehicle comprises an interchangeable cab enclosing an interior space for accommodating a crew of the utility vehicle, a chassis supporting the cab, cab interior components located within the interior space and detachably attached to the cab, cab exterior components located outside the interior space and detachably attached to the cab, and an interface device for connecting the cab interior components to the cab exterior components, wherein the cab interior components are detachably connected to the interface device by means of internal plug connections, and wherein the cab exterior components are detachably connected to the interface device by means of external plug connections.

[0005] Because the commercial vehicle has the interface device, it is possible to quickly and easily separate the cab interior components and the cab exterior components when replacing the cab, so that the cab interior components and the cab exterior components can be removed before the cab is replaced and can be easily reinstalled in or on the cab after re-installation of the same or a different cab.

[0006] 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 the 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.

[0007] The driver's cab is preferably protected. However, the driver's cab can also be unprotected. In this context, "protected" means specifically that the driver's cab is armored. In particular, the driver's cab is protected against gunfire, booby traps, improvised explosive devices (IEDs), mines, or similar threats. The driver's cab can also be referred to as the driver's cabin or driver's cab. The driver's cab is suitable for accommodating the crew, for example, a driver and at least one passenger. The driver's cab can, for example, be constructed of or incorporate armored steel plates. However, aluminum alloys, ceramic composites, and / or fiber-reinforced composites can also be used.

[0008] 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.

[0009] The cab preferably comprises a 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. A cab roof is positioned opposite the cab floor. In particular, the cab shell is replaceable. Doors may be provided on the cab side walls.

[0010] The fact that the cab is "interchangeable" means, in this case, in particular that the cab, especially the cab shell, is replaced, whereby the cab interior and exterior components are installed in or attached to a new cab or cab shell. The cab or cab shell is interchangeable, in particular, by removing the cab from the chassis. Preferably, the cab interior and exterior components are removed beforehand, so that only the cab shell remains and can be replaced.

[0011] The cab's front wall, rear wall, side walls, roof, and floor enclose the cab's interior, thus separating it from its surroundings. The interior can be accessed from the outside via doors, as previously mentioned. The cab floor is preferably multi-curved. In particular, at least in sections, the cab floor can have an egg-shaped or ovoid geometry. The cab floor is specifically optimized for mine protection.

[0012] The cab interior components can include, for example, control units for turn signals, hazard warning lights, lighting, an anti-lock braking system (ABS), an electronic stability program (ESP), any locking mechanisms, a reduction gear control, windshield wiper control, or the like. Furthermore, the cab interior components can include an air conditioning unit, a ventilation system, a parking brake, and / or a transmission control unit for the commercial vehicle. In particular, electrical and / or electronic cab interior components, pneumatic cab interior components, and / or hydraulic cab interior components may be provided.

[0013] The cab exterior components can include, for example, turn signals, headlights, a windshield wiper system, brake hoses, hydraulic cylinders, a braking system, or the like. In particular, electrical and / or electronic cab exterior components, pneumatic cab exterior components, and / or hydraulic cab exterior components may be provided.

[0014] The interface device allows for the electrical and / or electronic, pneumatic and / or hydraulic connection of the cab's interior components to the cab's exterior components. Internal and external connectors are provided to connect and disconnect these components. For example, these internal and external connectors are mounted on the interface device. In fact, the internal and external connectors are integral parts of the interface device.

[0015] According to one embodiment, the commercial vehicle has electrical and / or electronic cab interior components that are detachably connected to the interface device by means of internal electrical and / or electronic plug connections, and electrical and / or electronic cab exterior components that are detachably connected to the interface device by means of external electrical and / or electronic plug connections.

[0016] In its simplest form, an electrical interior cab component can be a switch for turning an electrical exterior cab component, such as a headlight, on and off. An "electronic" interior cab component, however, refers specifically to one with an electronic circuit that includes at least one active component, such as a semiconductor device. For example, such an electronic interior cab component could be the control unit of an anti-lock braking system (ABS).

[0017] According to another embodiment, the commercial vehicle has pneumatic cab interior components which are detachably connected to the interface device by means of internal pneumatic plug connections, and pneumatic cab exterior components which are detachably connected to the interface device by means of external pneumatic plug connections.

[0018] This makes it possible, for example, to connect components of a commercial vehicle's braking system using the interface device. For instance, a brake pedal is a pneumatic component located inside the cab, whereas a brake line mounted externally on the cab can be a pneumatic component located outside the cab. In this case, a compressed air braking system is used.

[0019] According to another embodiment, the interface device is arranged outside the interior and is detachably attached to the driver's cab.

[0020] In particular, the interface unit is mounted on the front wall of the cab. The interface unit can be bolted to the front wall of the cab. This allows for quick removal and installation of the interface unit.

[0021] According to another embodiment, the cab interior components are mounted on a common system carrier arranged within the interior, wherein the system carrier can be mounted on and removed from the cab as an assembly.

[0022] In particular, the system carrier can be detached from the cab and removed from the cab with the doors open. The system carrier is preferably composed of a multitude of sub-components, which are, for example, bolted, riveted, and / or welded together. The system carrier preferably supports all cab interior components. For this purpose, the cab interior components can be permanently connected to the system carrier.

[0023] According to another embodiment, the system carrier is connected to a front wall of the cab by means of deformation elements arranged centrally along a transverse direction of the cab.

[0024] Preferably, at least two such deformation elements, in particular a first deformation element and a second deformation element, are provided. However, the number of deformation elements is arbitrary. Four or six such deformation elements can also be provided. For example, the system carrier is bolted to the deformation elements, with the deformation elements in turn being bolted to the front wall of the driver's cab. The deformation elements are plastically deformable in the event of an impact on the commercial vehicle. The deformation elements are capable of converting kinetic energy into deformation energy. The deformation elements can also be referred to as absorption elements or crash elements. In the event of an impact on the commercial vehicle, the deformation elements can absorb energy, particularly once. The deformation elements can have a C-shaped geometry in cross-section.If the deformation elements are damaged during an impact on the commercial vehicle, they can be easily replaced. The deformation elements thus protect the system carrier from damage in the event of an impact on the commercial vehicle.

[0025] According to another embodiment, the system carrier is connected to the front wall of the cab by means of connection points provided adjacent to the cab side walls.

[0026] Preferably, first and second connection points are provided, spaced apart from each other along the transverse direction. The deformation elements are positioned between the first and second connection points along the transverse direction. The connection points can be bolted connections. For example, five first and five second connection points are provided. However, the number of connection points is arbitrary. The system carrier is preferably connected to the cab, in particular to the cab's front wall, only by means of the deformation elements and the connection points. This allows for simple and quick disassembly and assembly of the system carrier.

[0027] According to a further embodiment, the interface device is detachably attached to the front wall of the driver's cab, wherein the front wall of the driver's cab has an interface opening, and wherein the interface device both covers the interface opening and seals it in a liquid-tight and gas-tight manner.

[0028] Preferably, the cab front wall has a first interface opening and a second interface opening. A first interface device is associated with the first interface opening, and a second interface device is associated with the second interface opening. Furthermore, the cab front wall can have a third interface opening, which is preferably rectangular. A third interface device can be associated with the third interface opening. In addition, the cab front wall can have a fourth interface opening with a fourth interface device and a fifth interface opening with a fifth interface device.Preferably, the first interface device and the second interface device are positioned between the fourth and fifth interface devices when viewed along the transverse direction, with the third interface device preferably being arranged between the first and second interface devices.

[0029] According to another embodiment, the interface opening is polygonal, in particular octagonal, or round.

[0030] In principle, the interface opening can have any geometry. The octagonal or eight-sided geometry of the interface opening particularly prevents cables routed through the front wall of the driver's cab from being kinked. Specifically, the first and second interface openings are each polygonal, particularly octagonal. The third, fourth, and fifth interface openings are preferably rectangular. The third interface opening preferably runs along the transverse direction. The fourth and fifth interface openings preferably run along the vertical direction.

[0031] According to another embodiment, the interface device has an interface housing that both covers the interface opening and seals it in a liquid-tight and gas-tight manner.

[0032] The interface housing can preferably be a bent sheet metal component. The interface housing can also be a welded component. The interface housing can also be made of a composite material, in particular a fiber-reinforced composite material. A sealing element can be provided between the interface housing and the front wall of the driver's cab, which serves to provide a liquid-tight and gas-tight seal.

[0033] According to another embodiment, the interface housing is polygonal, in particular octagonal, or round.

[0034] The interface housing can, in principle, have any geometry. However, the geometry of the interface housing is adapted to the specific geometry of the corresponding interface opening in the front wall of the driver's cab.

[0035] According to another embodiment, the interface housing encloses a housing interior facing the interior, wherein the inner connectors are arranged inside the housing interior, and wherein the outer connectors are arranged outside the housing interior.

[0036] In particular, the internal and external connectors are electrically and / or electronically, pneumatically and / or hydraulically interconnected through the interface housing. The interface housing can have any number of internal and any number of external connectors. Preferably, the number of internal connectors corresponds to the number of external connectors.

[0037] According to another embodiment, the interface housing has a housing front wall which is arranged parallel to and spaced apart from the cab front wall, and several housing side walls which are oriented perpendicular to the housing front wall, wherein the inner plug connections and the outer plug connections are attached to the housing side walls.

[0038] The housing side walls are oriented at an angle to each other, resulting in an octagonal or octagonal geometry of the interface housing. Preferably, eight housing side walls are provided. In particular, the topmost and bottommost housing side walls are free of connectors.

[0039] According to a further embodiment, the interface housing has a flange plate with which the interface housing is connected to the front wall of the driver's cab, in particular screwed on, wherein the housing side walls are arranged between the front wall of the housing and the flange plate.

[0040] In particular, the housing side walls connect the housing front wall to the flange plate. Preferably, the housing side walls are oriented perpendicular to the housing front wall and perpendicular to the flange plate.

[0041] According to another embodiment, struts running along a vertical direction of the cab are attached to the front wall of the cab, serving as anchor points for armor plating and / or design elements attached to the cab.

[0042] The armor plating is applied if the cab is protected. If the cab is unprotected, design elements, such as sheet metal or panels, are attached to the struts. A bolted connection may be used for this purpose. The number of struts is arbitrary. For example, four such struts are provided.

[0043] The term "one" here is not necessarily to 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 above and below this number are possible unless otherwise specified.

[0044] Other possible implementations of 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. In such cases, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the commercial vehicle.

[0045] Further advantageous embodiments of the commercial vehicle are the subject of the dependent claims and the exemplary embodiments of the commercial vehicle described below. The commercial vehicle will be explained in more detail below with reference to preferred embodiments and the accompanying figures.

[0046] In the figures, identical or functionally equivalent elements have been given the same reference symbols, unless otherwise indicated.

[0047] The Fig. Figure 1 shows a schematic side view of an embodiment of a commercial vehicle 1.

[0048] 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.

[0049] Commercial vehicle 1 is assigned a coordinate system with a longitudinal direction (x-direction), a transverse direction (y-direction), and a vertical direction (z-direction). The directions x, y, and z are oriented perpendicular to each other. The z-direction is oriented parallel to a gravity direction (g). The gravity direction (g) is oriented in the orientation of the Fig. 1. Oriented from top to bottom.

[0050] 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.

[0051] 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.

[0052] 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. In the Fig. Figure 1 shows a structure 15 in the form of a container.

[0053] 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.

[0054] The Fig. Figure 2 shows a schematic front view of an embodiment of a driver's cab 11 as previously mentioned for the commercial vehicle 1.

[0055] 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.

[0056] 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 located within the cab 11 and thus within the interior 12. The first seat 27 can also be referred to as the driver's seat. The second seat 28 can also be referred to as the passenger seat. The third seat 29 can also be referred to as the middle seat, since, viewed along the y-direction y, it is positioned midway between seats 27 and 28.

[0057] 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.

[0058] The Fig. Figure 3 shows a schematic front view of an embodiment of a cab front wall 23 as previously mentioned. Fig. Figure 4 shows a schematic perspective view of the cab front wall 23. The following refers to the Fig. 3 and Fig. 4 referenced simultaneously.

[0059] In the Fig. Figure 4 shows the cab floor 18 next to the cab front wall 23. The cab floor 18 has a recess 30 molded centrally along the y-direction y. The recess 30 projects inwards into the interior 12 of the cab 11 and extends along the x-direction x. Viewed from the surroundings 13, the recess 30 curves away from the surroundings 13 and inwards into the interior 12. For example, the recess 30 can accommodate a drivetrain of the commercial vehicle 1, in particular a transmission tunnel.

[0060] A first fastening element 31 and a second fastening element 32 are attached to the cab floor 18. The fastening elements 31 and 32 can be bolted and / or welded to the cab floor 18. The fastening elements 31 and 32 are preferably welded components. The cab 11 can be connected to the chassis 2 by means of the fastening elements 31 and 32. For this purpose, hinges, for example, can be mounted on the fastening elements 31 and 32, which allow the cab 11 to pivot relative to the chassis 2.

[0061] The cab front wall 23 comprises a frame section 33 that supports the windshield 24, in particular the windshield sections 25, 26. The frame section 33 can, for example, have two openings 34, 35, in particular a first opening 34 and a second opening 35, into which the windshield sections 25, 26 are inserted. The openings 34, 35 are separated from each other by a strut 36. However, the frame section 33 can also support a continuous windshield 24 that is not divided into two windshield sections 25, 26.

[0062] The cab front wall 23 includes, in addition to the frame section 33, a [missing information] oriented in the Fig. 3 and Fig. 4. Wall section 37 is arranged below frame section 33. Frame section 33 and wall section 37 are firmly connected to each other. Frame section 33 and wall section 37 can, for example, be welded together. Furthermore, it is also possible that the cab front wall 23 is a single-piece component, in particular a single-piece component made of the same material. "Single-piece" or "one-piece" means that frame section 33 and wall section 37 form a single component, namely the cab front wall 23. "Single-piece" means that the cab front wall 23 is made entirely of the same material, for example, a steel alloy or an aluminum alloy. However, composite materials can also be used.

[0063] Several struts 38, 39, 40, 41 extending along the z-direction are attached to wall section 37. These struts can be, for example, profile beams. The number of struts 38, 39, 40, 41 is arbitrary. The struts 38, 39, 40, 41 are spaced apart from each other along the y-direction y. The struts 38, 39, 40, 41 can be, for example, bolted and / or welded to wall section 37. The struts 38, 39, 40, 41 serve as attachment points or anchor points for armor plating and / or design elements attached to the cab 11. If armor plating is attached, the cab 11 is protected. In the event that design elements are attached, cab 11 is unprotected.

[0064] The cab front wall 23, in particular wall section 37, is penetrated by a first interface opening 42 and a second interface opening 43. The two interface openings 42, 43 are spaced apart from each other along the y-direction y. In particular, the first interface opening 42 is located below the first opening 34 of the frame section 33 when viewed along the z-direction z. Accordingly, the second interface opening 43 is located below the second opening 35 of the frame section 33 when viewed along the z-direction z.

[0065] The two interface openings 42, 43 are preferably identical in design. Each interface opening 42, 43 has an octagonal or eight-sided geometry. However, other geometries, such as round or rectangular, are also possible. Viewed along the z-direction, each interface opening 42, 43 is wider at the top than at the bottom.

[0066] Furthermore, the cab front wall 23, in particular wall section 37, includes a third interface opening 44, which is arranged between the first interface opening 42 and the second interface opening 43. The third interface opening 44 is rectangular. The third interface opening 44 extends along the y-direction y. Below the third interface opening 44, an opening 45 is provided that penetrates the wall section 37. The opening 45 can be closed by means of a plate or a sheet. A connection for an air conditioning unit can be arranged at the opening 45.

[0067] Furthermore, the cab front wall 23, in particular wall section 37, has a fourth interface opening 46 and a fifth interface opening 47. The interface openings 46, 47 are rectangular and extend along the z-direction z. The two interface openings 42, 43 are positioned between the two interface openings 46, 47 when viewed along the y-direction y, with the third interface opening 44 being arranged between the two interface openings 42, 43 when viewed along the y-direction y.

[0068] The Fig. Figure 5 shows a schematic perspective sectional view of the driver's cab 11. Fig. Figure 6 shows another schematic sectional view of the driver's cab 11. Fig. Figure 7 shows a schematic perspective view of the driver's cab 11. The following refers to the Fig. 5 to 7 were referenced simultaneously.

[0069] A system carrier 48 is mounted within the cab 11, that is, in the interior 12. The system carrier 48 can be mounted to and removed from the cab 11 or the cab shell 19 as a single unit or as an assembly. Specifically, the system carrier 48 is connected to the cab front wall 23, particularly to wall section 37, on the inside by means of deformation elements 49, 50 arranged centrally along the y-direction y on the cab 11, in particular on the cab front wall 23. The number of deformation elements 49, 50 is arbitrary. At least two deformation elements 49, 50 are provided. A first deformation element 49 and a second deformation element 50 can be provided. However, four or six deformation elements 49, 50 can also be provided.

[0070] The deformation elements 49, 50 are plastically deformable upon impact of the commercial vehicle 1 or the cab 11. The deformation elements 49, 50 are capable of converting kinetic energy into deformation energy. The deformation elements 49, 50 can also be referred to as absorption elements or crash elements. In the event of an impact of the commercial vehicle 1 or the cab 11, the deformation elements 49, 50 can absorb energy, particularly on a single occasion. The deformation elements 49, 50 can be bolted and / or riveted to the system carrier 48 and the cab front wall 23, in particular to the wall section 37. The deformation elements 49, 50 can have a C-shaped cross-sectional geometry.

[0071] In the event of an explosion affecting the commercial vehicle 1 or the cab 11, the system carrier 48 can be removed and the deformation elements 49, 50 can be replaced. The system carrier 48 can then be reused, provided it is undamaged. If the cab 11 and / or the cab shell 19 is damaged by the explosion, the undamaged system carrier 48 can be installed in a new cab shell 19. In particular, the deformation elements 49, 50 protect the system carrier 48 from damage caused by the explosion.

[0072] In addition to the deformation elements 49, 50, the system carrier 48 is connected to the cab front wall 23, in particular to wall section 37, by means of first connection points 51, 52, 53, 54, 55 and by means of second connection points 56, 57, 58, 59, 60. The connection points 51, 52, 53, 54, 55, 56, 57, 58, 59, 60 are preferably bolted connections. The first connection points 51, 52, 53, 54, 55 are arranged adjacent to the first cab side wall 21, and the second connection points 56, 57, 58, 59, 60 are arranged adjacent to the second cab side wall 22.

[0073] As previously mentioned, the system carrier 48 is an assembly that can be removed from the driver's cab 11 as a single unit. To remove the system carrier 48 from the driver's cab 11, the connection to the deformation elements 49, 50 and the connection at the attachment points 51, 52, 53, 54, 55, 56, 57, 58, 59, 60 are released.
