Description

Armored mine-endangered vehicle The invention relates to an armored, mine-endangered vehicle with a

different purposes customizable replacement module according to the preamble of the main claim. Such an exchange module can easily give the vehicle a multi-roll capability. So far, replacement modules on vehicles are particularly in use when they contain consumable materials, such as in armored vehicles z. As ammunition, in other vehicles and gas tanks or the like. In trucks exchange modules in the form of different trailers or transport containers on a cargo bed are known. For example, semi-trailers or tractors can now be separated from a section of a semitrailer tractor that remains on site.

In armored mine-endangered vehicles, however, one would like to leave neither an exchange module in place, nor to leave another unit stationary, but it is in particular an armor against it provided that in the context of asymmetric warlike missions an attack by mines. In the case of armored vehicles, a floor pan is often severely deformed by a mine action, as a result of which the persons in the interior of the vehicle, such as the facility, could be damaged. To avoid this is the aim of the invention. Obviously, the bottom pan would be stiffer and designed as an exchange module to absorb all the energy. This is not satisfactory because of the limited space. In addition, the people inside are at every shock wave that deforms the armor endangered.

The replacement of the floor pan, which is in communication with the drive and in particular the axes, is already possible after damage, but consuming and is therefore carried out in specialized workshops.

In general, it is desirable in refueled vehicles that the occupants are protected against the action of the mine, which generally acts on the vehicle from below. All types of damping materials between floor pan and people require a lot of space, which would increase the total size of the vehicle too much for a given interior dimensions. About special seats, which may be affected by mine action

CONFIRMATION COPY deforming bottom trough of the vehicle and the ground connected to it are largely decoupled, but can be protected in the prior art, at least the back of a soldier. Also, footpegs are already known in the art which are designed to minimize the shock effect that can be exerted on the feet of the occupants in a mine explosion over the ground.

EP 1564 519 Bl discloses an armored mines endangered vehicle with the

Features of the preamble of claim 1. In this, however, the side walls and the floor of the vehicle are formed by elements of the exchange modules. But this is disadvantageous for various reasons.

The invention is therefore based on the object to ensure protection of persons in the vehicle against shock with great certainty and simple means.

The invention is solved by the features of the main claim. The dependent claims give advantageous embodiments again.

In particular, it is advantageous that a long and non-straight path for the shock waves is provided by a module that is only about the explosion shock absorbing and distributing wall areas with the probable location of the explosion at the bottom of the vehicle chassis in conjunction.

This module is inserted into a vehicle chassis provided with an upwardly open space in its interior, wherein the free space is bounded by side walls, rear wall, floor and front. The module will then communicate interchangeably at its edge over the walls and front with the vehicle chassis of the vehicle, the interior facilities and / or equipment to be provided for various purposes being interchangeably attached to the module.

Through a distribution of the shock wave over the entire vehicle will be in

Return direction, ie, spread over the trusses inwards into the interior, only little energy, if only because the Schockenergie reached at different times respective trusses. Therefore, the invention for various uses provided specific devices and / or devices on the module quickly provided with this interchangeable and shock-protected, and also protects the occupants of the vehicle. Next, all on the module can be swapped with this quickly and interchangeably

protected against shock, and also protected the occupants of the vehicle. Further, all of the devices on the module can easily be relocated to the reserve chassis, while maintaining internal connections and tuning, and only a few connectors provide sensor and power lines from the chassis to the devices

are to be connected.

These connections from chassis-side ports to ports on a roof or mission module are standardized. According to the invention, they are provided in the region of a traverse present in all modules or in the area of a rear side of the chassis provided with enlarged armor protection. Standardized interfaces are provided on a base vehicle and on the individual mission modules in such a way that each mission module can be quickly and safely connected to the infrastructure of the base vehicle. In particular, but not limited to the following list, these interfaces will include, for example, the supply or replacement with: electrical energy, electronic signals for communication / network, air (for heating / conditioned air / possibly compressed air).

This allows all required connections within the shortest possible time

can be connected in order to save time during the conversion, on the one hand, and to keep the actual procedure of connection as simple and secure as possible, so that nothing is forgotten.

For example, the interfaces of the module can be easily seen vertically superimposed on one of the trusses, on its vertically extending, outwardly facing side surface. The interfaces of the chassis are then arranged adjacent to each other accordingly adjacent.

The base vehicle will provide interfaces for all planned types of mission modules, which may not always be used, depending on the type of deployment module used. At the mission module, those ports are provided which are necessary for the operation of the respective mission module type. It is conceivable to have a redundancy too allow, and in case of failure either an interface on the mission module or a connection to the chassis in an alternative way, the respective supply interface or communication interface. Such redundancy would be made possible by a duplication of the interfaces provided on another crossbar, respectively. Backup interfaces can be designed so that they can only be connected by special adapters that connect two otherwise non-connectable (eg, female-female contacts) interfaces.

In a preferred embodiment, a plurality of at least three, but often by doubling eight or more trusses are provided on a roof panel of the module, which hangs a running floor, which thus has no contact with a lateral, front or rear wall structure, in particular neither on Edge still has direct contact with the floor of the vehicle chassis in its surface. Rather, he will maintain a distance that allows the ground to howl in the event of a mine explosion of expected strength without reaching the walking floor hanging from the roof panel.

The module will provide an open frame to the facilities below only over the suspended trusses to which a floor hangs. Own walls that limit the module, for example, container-like, are not provided on the longitudinal or front sides of the suspended truss structure. All closing surfaces that may be

Intended facilities inside to limit, are designed so that they are not in communication with the roof panel of the module and the ground, but are advantageously spaced from each other. In particular, all facilities in the interior, including the running floor on which the feet are placed while driving, connected to trusses with the roof panel. These trusses can be provided as a hollow profile in a number of at least three to well over a dozen, wherein it has proven to be beneficial to improve the vibration characteristics by doubling two side by side perpendicular and firmly connected with each other square profiles. Due to the increased stiffness natural vibration excitations are avoided

Further, some of the trusses that have no duplication, and other trusses, in which it offers, for example, due to the interior geometry, in some Distance from each other (proposed as a distance one to two Traversendicken), creating a quasi-doubling. A preferred embodiment avoids to arrange a traverse in each of the corner regions of the floor, but instead arranges the majority of the traverses in the center, so that the loads are preferably arranged again in the middle of the roof plate from the side of the free space which potentially transmits shockwaves ,

In this way, the stiffening of the module can be achieved without getting in

undesirably results in a transmission of shock waves to the ground and the devices attached to the trusses.

10

Some devices may also be permanently connected to the vehicle, such as the fire extinguisher system and the engine of the actual vehicle

Connecting facilities. On the other hand, facilities can also be subsequently connected to the module after it has been used in a vehicle chassis. 15 For example, equipment that does not fit through the recess in the chassis can still be attached to other equipment and / or the roof panel trusses.

On the other hand, for. B. the driver's seat be provided independently of the module, because he is usually already decoupled itself and anyway spatially separated from commander and team seats.

20

In a particular embodiment, a crane is provided which is fixed to the module at the top, wherein the winch for operating the crane occupies a large part of the interior of the vehicle. Advantageously, it thus becomes part of the module and is decoupled from the ground. When pulling the winch rope it will be supported against the roof plate 25 and therefore do not have to be zuggesichert secured as part attached to the floor of the vehicle, An attachment to the floor pan would be an undesirable bridge for the shock wave energy.

It is also proposed to use part of the soil, for example four

_3-0 hiei_fiiutf> r £ es £ ^ - still to be strengthened (with double thickness, for example) and to anchor the winch there to guarantee necessary counterforces. Also, a generator for generating the electrical current for, for example, the winch may be provided on a portion of the tread attached to the module. The fact that, for example, seats, but also tables and footrests are attached to the module, resulting in the shock wave in a mine explosion significantly longer paths over which the shockwave energy is dissipated or distributed with superposition, so that the amplitude decreases overall. At the same time in this way a simple interchangeability of the entire interior to various applications, for example as

Rescue vehicle, as a command vehicle, or as a recovery vehicle possible.

This simple interchangeability is a logistical advantage, since so only a plurality of modules must be carried according to the possible purposes, and need to be available for receiving the modules vehicle chassis in lesser quantities to be present (only as many as at the same time in use). In particular, it is then not necessary to provide complete specialized reserve vehicles for each purpose, but a few reserve chassis, which are easily adaptable by inserting appropriate modules to the respective purposes.

Finally, there is the further advantage that in a mine explosion, the devices provided inside the vehicle on the module as well as the persons are subjected to lower shock wave energies, so that the probability increases that a module still retains its functionality even if the chassis is damaged ,

^"" Durürreinen to the Weary l ^"ufcer traverses from Däcrrherabhangenden Bölden, the above ^- is ^{^} the bottom of the mine explosive vehicle suspended by a wide margin, the provision of special footrests for the occupant of the vehicle is no longer needed, the distance to this suspended. Running floor of the actual armored floor of the vehicle is 20-40 cm, preferably 35 cm depending on the

Armor of the mine-prone vehicle and pre-determined possible bending deformations that could result from mine explosions on the armored vehicle floor. In this way, a distance is selected, which spaced the walking floor so far from the armored underbody of the vehicle chassis, that a bulge does not reach the walking floor. In a preferred embodiment, the walking floor in the front area of the vehicle is then further away from the subfloor than in the rear area. Seats on which the vehicle occupants sit on, for example, the various devices provided inside the vehicle are advantageously also attached to the trusses which are suspended vertically from the roof of the module, or attached to the suspended floor such that by the long paths that a shock wave must go through in the walls and trusses, deflections that could endanger a vehicle occupant, are significantly reduced.

With regard to the shaping of the module, it is proposed to provide a peripheral bearing edge on the roof edges, which are connected to the walls, to which the module can be placed. It is also possible to form a variant of the module in two pieces, with a front area with Turmluke and a rear area with other equipment, being suspended on each of the two (sub-) modules via trusses own running floor. In a less preferred embodiment could be dispensed with a roof edge. However, ElrT-roof edge has its own, the vehicle stiffening function, which he can in particular perceive when the roof edge is rounded at the corners for the transmission of forces. In addition, a wider overlap is better at creating an ABC leak at the joint.

In order to create a firm and force-transmitting connection at the junction between the module and the vehicle chassis, which securely holds the module to the vehicle chassis even after a mine explosion, a plurality of bolts in corresponding bolt holes are provided along the edges. For example, it is proposed to make an intimate connection of the module with the wall and the armor of the vehicle with bolts in a number of 5-20 per edge.

Since the module as a whole, with its provided for the interior seating but also with all existing, not only electronic equipment and the like has a not insignificant weight, the necessary when replacing or installing the module fitting into a base vehicle is not trivial.

It is therefore proposed to provide vertical guides, which when lowering a hanging example of a crane module in the space inside the Vehicle chassis set the module in its angular position and longitudinal orientation as soon as the guides have begun to grip the module.

In particular, it is proposed that a fixed to one of the longitudinal sides, ^~ provide is approximately vertically extending ^~ St, fits the m a correspondingly provided in abgehängtem bottom of the module groove during the lowering of the module and on the horizontal along the running ground in its orientation in at least three Directions is maintained.

Preferably, at least two such guides are provided, which also not point-symmetrical, but for example, both in a rear area of the

Longitudinal sides of the vehicle are arranged so that an orientation of the module in the tank is immediately recognizable even under adverse conditions and the module can never be lowered the wrong way around even with any missing markers. In fact, however, due to the Turmluke usually provided in the front area of the module (in military armored vehicles) a correct orientation is also based on the facilities provided on the upper side of the module

For example, cranes or gun fasteners for each clearly. In an alternative embodiment of the module, the floor area after installation can be increased laterally to bridge at least existing gaps. For this purpose, it is proposed rubber mats or similar flexible material on the edge of

Ground area to provide appropriate strength. Finally, in order to allow an exact fitting of the module in exact agreement with the bolt holes, it is proposed to provide conical pins and cooperating pin holes on the bearing edge and the free space covering roof panel. It will be advisable to provide the conical pins on the underside of the roof or the roof panel of the module, and to provide corresponding pin holes on the bearing edges in the region of the walls on the vehicle. This makes it possible, if necessary, to put modules, which are not equipped according to the pin / pin hole system according to the vehicle, for. B. a simple weather and dust protection. For storage and transport of the modules is proposed, the height of the module, ie, in particular the length of the trusses, with which the bottom element is suspended from the roof panel of the module, in its height exceeding lower portion of a conventional transport container from an upper portion detachable To make this lower section then with a support edge and preferably with

To provide pin holes receptacles to sink a module in the lower portion and then put the upper portion of the container on the lower portion again. If the roof panel extends to the edge, its thickness must be taken into account when dimensioning the two partial heights of the container sections.

In this way, a lower section and upper section even then have the height of a conventional transport container, if a module in the lower

Part section is inserted.

The upper section of the transport container then serves to protect the top of the module and any devices mounted thereon. Only devices that are larger than the free space provided by the upper section would need to be transported separately. The latter, of course, only if the standard dimensions of a transport container to be respected. The upper portion of the transport container is formed without module to the lower portion fastened.

Further advantages and features of the invention will become apparent from the following

Description of the drawing. Showing:

1 is a schematic drawing in which the assembly of a module and a chassis is illustrated,

Fig. 2 is a schematic representation of a tank chassis of Fig. 1, referred to as the mission module replaceable part, which is provided with a roof plate and a plurality of trusses. Are clear in Figure 3 notches 52 for adaptation to the armored vehicle chassis shown in Fig. 2 recognizable.

The chassis, as can be seen in Figs. 2 and 1, has recognizable chains in the lower part of the drawing and is listed in the manner of a light tank. The vehicle chassis has an approximately over the entire width reaching recess, which begins behind the hatch for the driver and extends to just before the rear wall of the chassis.

The recess is formed box-shaped, so that, as shown in Fig. 1, a box-shaped insert can be introduced. The insert has a roof panel 40 on its upper side and a running floor 30 as the lower boundary. In addition, a gun and two hatches can be seen on the roof panel. Between the roof panel 40, which will rest on an edge 42 on the chassis, and the walking floor 30, a plurality of trusses 24 are provided, which hold the walking floor 30 to the roof panel 40, without the walking floor 30 making contact with the floor. of the chassis receives.-

Rather, a not inconsiderable distance of all possible bulges of the bottom pan takes into account, between the floor 30 and the bottom pan or a top surface of the bottom pan 18 shown in FIG. 2 observed.

In Fig. 2, the substantially vertically running side walls 14, 16 of the vehicle are further shown, on which inside depending on the width of the edge 42 at the top nor facilities can be provided which must be present in each vehicle. Only institutions specific to each mission and those in direct contact with persons are expediently provided interchangeably at the roof or mission module,

The vehicle chassis is denoted by reference numeral 12 and reference numeral 50 designates a rod or a bracket which is attached to one of the wall regions as one (preferably several) guide elements and the counterguide to a groove 52 provided on the depending bottom 30 forms, as shown in FIG. 3.

FIG. 3 no longer shows the armored mine-protected vehicle as a whole, but only the replacement module 10 which can be adapted to the different purposes of use. posed. This replacement module 10 is inserted into the upwardly open space in the interior of the mine-endangered vehicle 12, wherein now not the previously existing space, but the intended replacement module bounded by the side walls 14, 16, the rear wall and the bottom 18 and the front of the vehicle chassis is.

The module 10 will protrude at its edge, namely with the edge of the roof panel 40, over a respective horizontal area of the walls and fronts of the vehicle to be interchangeably associated therewith. Larger areas with portions of vertical

Wall exchange is conceivable.

All available for the various purposes Innenreinrichtungen and or equipment are attached to the module 10 and are designed so interchangeable with this. In a preferred embodiment, seats 32 for the vehicle occupants and the interior components to be provided for the intended use are on trusses 24; 36 and / or the hanging floor 30 while leaving a free space to the walls and the fronts attached. In this way, they are not directly reached by the shock waves in a possible mine explosion, but only by the shock waves that move the roof panel 40. Crossbeams 38, in which the seats are shown attached in Fig. 3, reinforce the decoupling yet.

In addition, in FIG. 3, the roof plate 40 of the module 10, which fits onto a horizontal, peripheral bearing edge 42 and closes an opening over the free space in the vehicle, is provided with a plurality of straight side edges.

Not shown in Fig. 3 is a preferred embodiment in which the roof panel 40 is provided along its edges with bolt holes into which bolts for securing the roof panel at an upper edge 42 are screwed. A design of the bolt holes in the upper edge 42 as blind holes is possible.

Also not shown, but proposed in a further preferred embodiment, conical pins and cooperating pin holes can at least one support Edge cooperate with a watching, an opening in the vehicle covering roof panel 40.

Finally, it is proposed that, for the transport and storage of a module, a height of the lengths of the trusses superior lower portion of a transport container is formed with a support edge for a module that allows the mission modules can be transported in such transport containers, with an upper Part of the transport container releasably fastened on the lower portion of a module and which is formed on the fixed devices covering.
