Abstract

The armor shield (2) for a vehicle, as a protection against the explosion of a land mine and the like, is fitted to the exterior of the chassis. Mountings (4.1) are at the chassis, bonded to the armor plate, to transfer distortion forces from an explosion at the armor plate over the whole chassis. The armor plate has a wedge-shaped strap (7) to fit into the chassis mounting in a positive fit, for installation and replacement.

Description

Technical field

The invention relates to an arrangement for protecting a vehicle against the effects an explosive device, in particular a mine, at least one flat protective element is attached to the outside of a chassis of the vehicle.

State of the art

Protection from mines in vehicles, especially tanks, is for the safety of the Occupants and combat value maintenance, especially of mine clearance vehicles of significant Importance. Various approaches have already been used to improve protection. For example, the floor or the entire floor pan of the to be protected Vehicle reinforced. This was done by doubling the floor panel with a Metal plate or by using a floor plate with a greater thickness than it is necessary for design reasons with regard to the type of vehicle.

Since the vehicles for which such mine protection is sought are in every type of Should it be possible to use it off-road, this will often result in damage to the fastening the protection ordered. A damaged by the so-called "sitting" Protection is only conditional in the known systems, and if at all only complex to replace. Forces occurring, for example at a Explosion of a mine occur, only unsatisfactorily destroyed, so in most cases major damage to the underside of the vehicles despite the provision of protection arise which can make the vehicles in need of repair.

All known systems are unsatisfactory for the present and future situation.

Presentation of the invention

The object of the invention is to provide a protective element on the outside of a vehicle to attach that on the one hand optimal protection of the vehicle against an impact an explosive device is guaranteed, and on the other hand, the protective element is preferred is also interchangeable.

The solution to the problem is defined by the features of claim 1. According to the Invention is used to protect a vehicle against the effects of an explosive device, in particular a mine, at least one flat protective element on the outside of the Chassis of the vehicle to be protected attached. (In this sense, under chassis is a resilient structural part of the vehicle, e.g. B. the floor / Side wall construction of the vehicle understood.) The protective element is attached in this way attached to the chassis, that the and occurring in the event of an explosion of an explosive device deformation forces initially acting on the protective element in this way into the whole Chassis are transferred that a higher load capacity is achieved than if only the protective element would have to take over these forces alone. So are the forces like this It is important that the protective element is significantly deformed, at least these high forces partially introduced into the chassis, but in a way that is not too damage to the chassis. This can be thought of as the chassis is only elastically deformed, even if the protective element is at least partially plastic is deformed.

With this type of attachment, the chassis helps to destroy the deformation energy. Tanks in particular have a trough-shaped base, so that the attachment can be supported on the side walls of the trough-shaped bottom. By the Behavior of the chassis, which is comparable to a torsion beam, can cause higher deformation forces be taken over by the vehicle than this with the conventional Arrangements in which the protective elements are attached directly to the floor, the case is. Precisely because the chassis as a whole is stronger than the actual protective element trained, high forces can be taken over and plastic deformations at the same time on the protective element can be reduced so that the resulting damage be minimized.

The protective element is preferably a plate-shaped metal element. There is also the use of other materials such as those on Plastic base conceivable, provided that the explosion loads to be expected in the specific case can record in the desired measure.

The protective element is preferably attached to the chassis in an exchangeable or detachable manner. In particular, it should be possible for the user of the vehicle to take the protective elements can be attached or replaced with little effort and a few simple steps. So the protective elements can be assembled and disassembled as required. Will the For example, vehicles are used in safe situations (such as when moving from one place to another), the protective elements can be dismantled, for example reduces vehicle fuel consumption. Became a protective element damaged, it can be replaced with little effort. Preferably the Fastening of the protective elements designed such that the protective elements are also dismantled if deformations have occurred. (For example, in the brackets or connecting lugs are provided.) Of course Applications are also conceivable in which a long-term and possibly detachable fastening only makes sense with special effort. It is worth mentioning, for example upgrading older vehicles.

As a rule, several brackets are provided on the chassis, which at least fix a protective element. The brackets are made of cast steel, Forged steel or the like. For special vehicles, which are for use under special conditions such as in rooms with an aggressive environment special steels such as hardened steel can also be used. Preferably are these brackets in a parallel to a main surface of the protective element Direction arranged. This will cause the protective elements to move Loads in the direction parallel to their main surface largely prevented, which in particular is important for the use of vehicles in the field. The brackets are welded to the chassis in a preferred embodiment. Is next to it also an attachment of the brackets with other means such as screws executable. Care should be taken to ensure that the Screws themselves are not required for power transmission. This can e.g. B. thereby achieved that special forms are formed on the outside of the chassis with which the brackets can work together positively. The design of the Brackets is on the one hand from the outside design of the chassis and on the other hand depending on the design of the attachment. The greater the powers the more massive that have to be led into the chassis through the bracket the bracket must be designed. The arrangement of the brackets is designed so that the protective element is not torn away when the vehicle is seated off-road becomes. So that this condition is met, the brackets (e.g. by positive or non-positive structures) such that they are primarily the forces occurring in such a case take over and that only in the second place the fasteners are claimed. Any existing, protruding elements of the chassis are used, so that movements of the protective elements, which act in a direction parallel to their main surface are largely hindered.

The protective element is fixed to the brackets with fasteners. Preferably these fasteners are screws. There are other means such as spring pins or the like conceivable, especially if a detachable Connection is created in which the protective elements can be replaced. The brackets are also constructed in such a way that the fastening means in the case of a The impact of an explosive device remains essentially unencumbered. This means that used fasteners are only dimensioned to the load forces which by fixing the protective element (s) (essentially the dead weight of the protective element) and not to the much higher forces, for example causes an explosive device to explode.

Since the protective elements are only needed, for example during a maneuver or during A combat mission, which can be attached to the outside of the vehicle, is simple assembly prefers. Of course, this is particularly important when it comes to attach the protective elements to the particularly inaccessible underside of the vehicle. This problem occurs, for example, when mounting on a side wall mostly not on. For example, the protective element on the (horizontal) underside attached to the vehicle, it is mounted in a vertical direction (or vertically to the direction of travel of the vehicle). In a variant, there is also an insertion of the or of the protective elements provided in a direction which in the main plane of the Protective element lies. In relation to the direction of travel of the vehicle, it can therefore be pushed in be provided from the front or from the rear.

The dimensions of the protective elements are such. B. according to the available space and the geometry of the chassis so that the protective elements between the wheels can be mounted. So that the plates (which are typically made of Metal) can also act as protective elements, they must have a certain Have thickness. The total weight depends on the surface of the plate. Preferably care is taken that a single protective element is only so large that it can be easily Devices (e.g. a portable lifting device) are brought into the mounting position can. The lighter the protective elements, the easier the assembly. Especially the alignment, i.e. H. the positioning is proportionate to one lighter weight of the protective elements significantly simplified. Should the protective element cover the floor of the vehicle, for example, it is preferably at least so large that it extends from one side of the vehicle to the other, so that the fasteners can be attached without the user crawling under the vehicle got to. With several protective elements arranged directly next to each other the whole floor can be covered. Of course, it is also conceivable that the individual protective element from the rear to the front of the vehicle extends. When inserted, the protective elements are separated by a separate one Lifting device raised towards the chassis until they are in the position that they can be fixed to the brackets.

The brackets are designed such that they on or on the protective elements trained connection elements can accommodate. In a preferred embodiment the holder is provided with a slot in which a corresponding Connection element of the protective element is inserted. When exposed to explosion A force transmission should be ensured by positive locking. With at least a fastener, for example, with at least one screw Protective element fixed. Due to the shape of the Protection element and the appropriate dimensioning of the fasteners can Damage to the brackets due to the use of vehicles in the field largely be avoided. If an explosive device explodes below the Protective element is deformed (i.e. it undergoes a deflection). As a consequence of this a bending moment acts on the brackets. Because the brackets themselves are strong enough trained, they do not deform, but transfer the moment to the chassis. This ensures that the deformation forces are redirected to the entire chassis and the risk of damage to the vehicle is significantly reduced.

In a further embodiment of the holder, it has a C-shaped configuration. The longer free leg is attached to the side wall of the chassis and the shorter one free leg is gripped by the connecting element of the protective element. Preferably the connection elements are formed monolithically on the protective element. In addition, the connection elements are also designed as independent elements conceivable. However, the independent connection element must be designed in such a way that there are no high loads on the fasteners used. For fixation the protective element is at least one fastener per bracket intended. In a preferred embodiment are to support the fixation of the protective elements, especially when using the vehicle in the field, the connection elements in the longitudinal direction of the protective elements, on the direction of travel of the vehicle covered, U-shaped, so that the brackets are gripped laterally. If a possible shift of the protective element by protruding elements of the Chassis, for example protruding wheel arches largely prevented, can be the connecting element of the protective element can be designed as a straight connecting strap. On a U-shaped configuration of the connection element, which engages around the holder, can be dispensed with. If there is any displacement of the protective element, for example Prevents described above, the bracket can also be designed Z-shaped. One free leg is attached to the chassis and the second free leg serves to fix the protective element.

Further configurations of the brackets are conceivable. Depending on the shape of the chassis the brackets are adjusted so that they can transmit forces and torques are suitable. It is essential that the entire chassis to accommodate the resulting forces or deformation energies, especially in the event of an explosion Explosive device is used.

In a variant for fixing the protective element or elements with fastening elements clamping elements can be provided. The brackets are preferably as formed a kind of clamp, the inserted protective elements in a certain Meaning can be embraced. The clamping elements are, for example Wedge elements driven between the chassis and the protective element (s) be and so brace them together, resulting in a desired fixation leads. Since the fixation should be releasable, the driven wedge element is, for example to be arranged so that it is easily expelled against the original driving direction can be. A combination of a tube with is preferred as wedge elements used a wedge. That between the protective element and the floor of the vehicle Layed pipe is pushed apart with a wedge by driving the wedge in becomes.

Instead of forming separate brackets that are attached to the chassis and that The chassis can grip protective elements in such a way that they can be braced themselves have protruding elements, behind which the protective element is inserted can be. Separate protruding elements can be arranged on the chassis. Furthermore, existing protruding elements, such as wheel arches, can also be used or the like is used and, if necessary, enlarged in such a way that the inserted protective elements come to rest behind them and with the chassis Wedge elements can be clamped.

From the following detailed description and the entirety of the claims there are further advantageous embodiments and combinations of features of the invention.

Based on the schematic cross section shown in Figure 1 of the inventive The principle of operation is explained in the arrangement. The floor 1 is used to protect a vehicle, for example a tank, against the action of an explosive device, in particular a mine, provided with a metal plate 2. Between the wheel arches 3.1 and 3.2 Brackets 4.1 and 4.2 are arranged on each side of the vehicle, which the Wear the metal plate 2 at a distance (for example a few centimeters) from the floor 1. Per Protective element (metal plate 2) are z. B. four or more brackets are provided. For the Connection between the brackets 4.1 and 4.2 and the metal plates 2 are suitable Fasteners provided. The brackets 4.1 and 4.2 are on the bottom 1 and on the Side walls 5.1 or 5.2 (shown obliquely inclined in FIG. 1) of the vehicle in this way attached that with a load on the brackets 4.1 and 4.2 these with the side walls 5.1 and 5.2 and floor 1 interact. In the way of mounting the brackets 4.1 or 4.2 can be, for example, a welded or screw connection act. The metal plate 2 can in various ways with the holder 4.1 or 4.2 be connected. In a preferred embodiment, the holder 4.1 or 4.2 a recess on which to receive a correspondingly designed connection tab the metal plate 2 is used. These and others are shown in FIGS Variants of the connection connection of the metal plate 2 with the holder 4.1 described in detail.

So large are caused by the action of an exploding mine, for example Forces that the brackets 4.1 or 4.2 of the metal plate 2 want to deform, then the forces should be transferred to the side walls 5.1 and 5.2. The bottom 1 forms with the side walls 5.1 and 5.2 and the body of the vehicle (not shown here) preferably a closed frame. This makes it possible to experience higher forces to take over the entire vehicle than this when fastening protective elements the previously known type is the case.

Due to the deformation of the metal plate 2 when exposed to, for example, an exploding Mine shortens this. The connection tabs of the metal plate 2 act on the Brackets 4.1 and 4.2. For this reason, the brackets 4.1 and 4.2 must be such be trained to withstand these forces and at the same time the forces in the side walls 5.1 and 5.2 and to a lesser extent in the Floor 1 can initiate. This also defines the technical boundary conditions for the type of fastening set. The attachment of the bracket 4.1 or 4.2 on the side walls 5.1 or 5.2 and on the floor 1 must be designed such that the bracket on the one hand 4.1 or 4.2 is not torn off due to the action and on the other hand the forces are mainly introduced into the side walls 5.1 and 5.2. When designing The brackets 4.1 and 4.2 ensure that as much space as possible is available stands to transfer the forces. The bottom 1 of the Vehicle already existing recesses / elevations shared.

The principle is applicable to all vehicles on which there is a protective element on the outside is arranged.

FIG. 2 shows a detail section of a preferred embodiment of the arrangement. In this, the bracket 4.1 is welded to the side wall 5.1 and the bottom 1. In addition to this type of attachment, the bracket 4.1 is also attached other fasteners such as screws (not shown) can be executed. In this case, these fasteners may also have to act as a result of external forces resulting effects can take over what dimensioning the fasteners is to be considered and, for example, a larger cross section of the fastener leads to a dimensioning only on the total weight of the Metal plate 2 is the case. Furthermore, such fasteners are dimensioned rather deformed. The aim is to design the bracket 4.1 or 4.2 so that a special design or use of the existing design of the floor 1 and the side walls 5.1 and 5.2 the loads on the fasteners for the bracket 4.1 and 4.2 are kept as low as possible.

The brackets are provided with a recess 6 in this embodiment. Preferably is this recess 6 in the longitudinal direction, this on the direction of travel of the vehicle related, arranged continuously. The connecting strap 7 is inserted into this which is perpendicular to the main surface of the metal plate 2 and complementary in shape is formed for the recess 6. The whole metal plate 2 is between the Wheel cases 3.1 pushed under the vehicle. This insertion is preferably carried out by one ("left") or the other ("right") side of the vehicle in relation to the direction of travel. However, the metal plate 2 can also from the front or rear, this also on the Direction of travel of the vehicle. With a lifting device (not shown here) the metal plate 2 is raised and positioned such that it can be fixed to the brackets 4.1 or 4.2. The fixation is done with a fastener. In the embodiment shown, the holder 4.1 has a recess in which a screw 8 is inserted. The connection tab is preferably 7 provided with a thread designed according to the screw 8. The Fastening means arranged here primarily serve to fix the metal plate 2. This prevents the metal plate 2 from shifting when the vehicle is in the swampy terrain sinks and rests with the metal plate 2 on the ground. Further the metal plate is simultaneously in the vertical direction (i.e. against "falling") held. Instead of a screw 8 as a fastener, depending on the embodiment and weight of the metal plate even a pin is sufficient. (Of course you can several screws or pins can also be used.)

Depending on the size of the vehicle and the number of wheels, more than one metal plate 2 per Vehicle used. With a view to simple assembly, it is advantageous if the used metal plates are not too heavy. This has to do with the tools needed Montage effects. In the case of metal plates that are not too heavy, it may even be can be dispensed with a lifting device if the metal plate is not too heavy to to be lifted by several people. Such an assembly is also in the field easily executable. The metal plates used as mine protection are e.g. B. about 80 mm thick and have a mass of approx. 300 kg / m2. This information relates to Experience and can vary greatly depending on the vehicle and operating conditions. It is also not essential to the invention, what type of protective elements are arranged and how heavy they are. The other dimensions of the metal plates are so far important than they depend on the type of assembly. With the preferred side Assembly ("sideways" here refers to the vehicle or the direction of travel of the vehicle) the metal plate must be insertable between the wheels. The bigger the Wheelbase, the wider the metal plate can be. Furthermore, also the design of the floor has an influence on the dimensions of the metal plate, in particular if individual protruding elements of the floor for bracing the metal plate to be used.

If the metal plate 2 is now exposed to an explosive device, it shortens itself, as already described. The upper end of the connection tab 7 presses against the Bracket 4.1 outwards, referring to the side wall of the vehicle. The bracket is so massive, however, that it counteracts this pressure and thereby supported primarily on the side wall 5.1 and secondly on the floor 1. Because with this Arrangement for the resulting forces a larger area compared to a fastening, which only uses floor 1 to take over the forces is available the acting forces are better distributed and the effects of the deformation forces on the entire vehicle are lower in comparison.

As already mentioned, the metal plate 2 is also countered by the holder 4.1 or 4.2 kept moving. Because vehicles on which mainly such metal plates must be arranged, must be usable in almost every type of terrain, a metal plate be held such that when the vehicle is touched down no damage, in particular to the brackets 4.1 and 4.2 of the metal plate 2.

Figure 2a shows a perspective view of the arrangement described in Figure 2 from below to the floor of the vehicle. Individuals were used to clarify the arrangement hidden lines are shown in dashed lines. How to recognize from this illustration can, the connecting tab 7 protrudes over the edge of the bottom 1. The connection tab 7 is L-shaped and engages in the holder 4.1. The recess 6 of the Bracket 4.1 is tapered towards the side wall 5.1. The complementary in their form trained connection tab 7 can be guided in this recess 6 used be, which facilitates the positioning of the metal plate 2. Next are with this Embodiment two screws 8 arranged as a fastener for the metal plate 2.

The detail section in FIG. 3 shows an arrangement with a holder 9, which is illustrated spoken has a C-shaped configuration. The longer free leg 19 of the bracket 9 is attached to the side wall 5.1. As a variant for fastening with a Welding a screw 10 is arranged. When there is a heavy burden on the individual Screw 10 can have several screws along the side edge 5.1 and / or transversely thereto to be ordered. The shorter free leg 20 of the bracket 9 is used to hold the Connection bracket 11. The metal plate 2 is held with a screw 12, this Screw 12 can also be replaced by a spring pin or something similar, provided the total weight of the metal plate 2 allows this. Depending on the situation, more can be done here be arranged as a fastener. The holder 9 is of solid construction So that the support surface of the bracket is so large that the forces optimally on the side wall 5.1 and the bottom 1 can be transferred. The metal plate 2 can also in an area, preferably in the area of the holder 9 or even over the entire length of the metal plate 2, have a web 13. This is preferred for the connection Bottom 1 / side wall 5 or arranged in the vicinity thereof. Note that preferred no or only slight forces on the screw 10 and in particular on the Screw 12 act so that they have a main holding function and thus on the total weight of the metal plate 2 must be dimensioned. An acquisition of the Forces arising from the explosion of an explosive device is hardly possible only with screws or bolts as fasteners. The main task of these fasteners is the holding of the individual metal plates 2 and at the same time securing the Metal plate 2 before a shift, especially when the vehicle is sitting on the ground.

Figure 3a shows a perspective view of the arrangement described in Figure 3 represents, in order to secure against moving the metal plate 2, the connection tab 11 additionally has two side parts 14. These encompass the shorter free one Leg 20 of the bracket 9. By this measure, the loads on the Screw 12 significantly reduced, which is smaller dimensions of this screw 12 or a comparable fastener allowed.

With this type of arrangement, the connecting lug 11 or the metal plate 2 can go as far as be pulled over the edge of the floor / side wall so that 3.1 and 3.2 Recesses are necessary so that the metal plates 2 can be mounted. Will one such a recess would be tight, if one of the metal plates were moved 2 push them against the outer edge of the wheel housings 3.1 or 3.2, so that the freedom of movement the metal plates 2 would be additionally limited. This also leads to relief of the individual fasteners when attaching the metal plate 2 to the Brackets 4.

FIG. 4 shows a detail section of an arrangement with a Z-shaped holder 16. The shorter free leg 21 of this holder 16 is in the direction of the metal plate 2 aligned and the connecting tab 11 is attached to it with the screw 12. Becomes a web 13 is also arranged here, the shorter free leg 21 preferably extends up to to this web 13. In this embodiment, the use of a spring pin is opposite preferable to a screw because of the space available for attaching a tool in the cavity 17, which is due to the arrangement of the metal plate 2, especially when a Web 13 is present, and the bracket 16 is formed, are scarce. To take over the forces arising from the explosion of an explosive device and to redirect the forces the longer free leg 22 on the side wall 5.1 is preferably in the side wall 5.1 welded.

The detailed section shown in FIG. 5 shows an embodiment in which the arrangement is braced is. It is of crucial importance that the metal plate 2 to Edge of the wheel arches 3.1 is guided and a possible recess in these wheel arches 3.1 or 3.2 is made as short as possible. The metal plate 2 has a web 13, which must be arranged in the area of the wheel arches 3.1, but also via the entire length can be arranged with respect to the direction of travel of the vehicle. The Position with respect to the edge 15 results from the wedging elements used Dimensions and design of the wheel arches 3.1 and 3.2. The distance is also wider between the outer edge of the base 1 and the inner edge of the metal plate 2 Influence on the position of the web 13. The web 13 is preferably close to the edge 15 arranged. A tube 18 as shown here is used as an example as wedging elements and used a wedge which is driven into the tube. This will make the metal plate 2 pressed against the edge of the wheel arch 3.1 and so braced. In the event of an explosion The explosive body particularly presses the web 13 preferably close to the edge 15 on the floor 1. Thus, a substantial part of the force generated is on the side wall 5 derived. In this embodiment, the wedge elements used be designed such that the wedging can be released. This can ensure this that the driven wedge is so long that it is away from the other side can be expelled again from the tube 18, for example.

In summary it can be stated that the arrangement according to the invention on the one hand protection against explosive devices, in particular from mines in vehicles significantly increased and on the other hand a detachable connection of the protective elements on the vehicles. Nevertheless, damage to the brackets can Protective elements when using these vehicles in the field largely excluded become. If the protective elements are no longer required or they have to be replaced , they are easy to disassemble and can then be reassembled at any time.
