[0003] 1 COMMERCIAL VEHICLE

[0004] The present invention relates to a commercial vehicle, in particular a military commercial vehicle.

[0005] 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.

[0006] Against this background, one object of the present invention is to provide an improved commercial vehicle.

[0007] 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, 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.

[0010] 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 easily reinstalled in or on the cab after re-installation of the same or a different cab.

[0011] 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.

[0012] The cab is preferably protected. However, the cab can also be unprotected. In this context, "protected" means, in particular, that the cab is armored. Specifically, the cab is protected against gunfire, booby traps, improvised explosive devices (IEDs), mines, or similar threats. The cab can also be referred to as the driver's cab or driver's cabin. The cab is suitable for accommodating the crew, for example, a driver and at least one passenger. The cab can, for example, be constructed of or have armor plating made of armored steel plates. However, it can also be RMM24009PWO DPT24013 WO

[0015] Aluminium alloys, ceramic composites and / or fiber composites are used.

[0016] 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.

[0017] 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.

[0018] 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. RMM24009PWO DPT24013 WO

In particular, electrical and / or electronic cab exterior components, pneumatic cab exterior components, and / or hydraulic cab exterior components may be provided.

[0024] The interface device allows the cab interior components to be connected electrically and / or electronically, pneumatically and / or hydraulically to the cab exterior components. To connect the cab interior and exterior components, see RMM24009PWO and DPT24013 WO.

[0025] Rheinmetall MAN Military Vehicles Austria Ltd.

[0026] To separate the internal and external connectors, internal and external connectors are provided. For example, the internal and external connectors are mounted on the interface device. The internal and external connectors are, in particular, part of the interface device.

[0027] 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.

[0028] 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 a cab component with an electronic circuit that includes at least one active component, such as a semiconductor device. Such an electronic interior cab component could, for example, be the control unit of an anti-lock braking system (ABS).

[0029] According to a further embodiment, the commercial vehicle has pneumatic interior cab components that are detachably connected to the interface device by means of internal pneumatic connectors, and pneumatic exterior cab components that are detachably connected to the interface device by means of external pneumatic connectors. RMM24009PWO DPT24013 WO

[0032] 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.

[0033] According to another embodiment, the interface device is arranged outside the interior and is detachably attached to the driver's cab.

[0034] 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.

[0035] 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.

[0036] 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. RMM24009PWO DPT24013 WO

[0037] Rheinmetall MAN Military Vehicles Austria Ltd.

[0038] 7 According to a further 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.

[0039] 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, which in turn are 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 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.

[0040] 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.

[0041] Preferably, first and second connection points are provided, which are spaced apart from each other when viewed along the transverse direction. The deformation elements are located between the first and second connection points when viewed along the transverse direction.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] The term "one" 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 above and below the stated number are possible unless otherwise specified.

[0090] Rheinmetall MAN Military Vehicles Austria Ltd.

[0091] 14. Four axles 3, 4, 5, 6 are provided. This means that the commercial vehicle 1 is a four-axle vehicle in this case. However, the number of axles 3, 4, 5, 6 is arbitrary. The commercial vehicle 1 can also be a two-axle, three-axle, or five-axle vehicle. The commercial vehicle 1 preferably includes all-wheel drive. This means that all axles 3, 4, 5, 6 can be driven. The 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, 4 are steerable. All axles 3, 4, 5, 6 can also be steerable.

[0092] 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.

[0093] 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.

[0094] 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 – for example, in reverse – in the opposite direction to the RMM24009PWO DPT24013 WO

[0095] Rheinmetall MAN Military Vehicles Austria Ltd.

[0096] 15. The vehicle can move in the direction of travel 16 on the surface 17. The surface 17 can be a road or any terrain.

[0097] Fig. 2 shows a schematic front view of an embodiment of a driver's cab 11 as previously mentioned for the commercial vehicle 1.

[0098] The aforementioned coordinate system with directions x, y, z can also be assigned to the cab 11.

[0122] 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.

[0123] 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.

[0124] In addition to the deformation elements 49, 50, the system carrier 48 is connected to the cab in front of the wall 23, in particular to the 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.
