Definitions
- the invention relates to a mine protection system for protecting a military vehicle from detonating mines with two armor plates arranged at an angle to one another. Further objects of the invention form a vehicle underbody with a floor and a side wall arranged at an angle to the floor and a military vehicle with such a vehicle underbody.
- the anti-mine protection has armor plates which can be attached to the underbody of the vehicle from below and from the side, so that the armor plates are arranged at an angle to one another. Due to the angular arrangement, the lower armor plate can absorb detonation forces acting from below and the side armor plate can absorb detonation forces acting laterally.
- the mine protection is at the corner areas of the vehicle underbody, namely where the armor plates meet , often show weaknesses. Because if the armor plates are only materially connected to one another in these corner areas, such as by welding, for example, detonation forces acting on the armor plates can easily lead to tensions and damage to the mine protection system resulting therefrom.
- EP 2 561 307 B1 discloses, for example, a mine protection for the underbody of a vehicle with armor plates which are arranged on the floor and the side walls of the vehicle. Instead of the armor plates colliding in the corner areas of the vehicle underbody, the side armor plate overlaps the lower armor plate, see above that the corner areas can be protected accordingly by the overlapping part of the armored plate on the side.
- the overlapping part of the lateral armor plate Because of the overlapping part of the lateral armor plate, it can support itself against the lower armor plate when detonation forces act from the side, so that at least part of the lateral detonation forces can be absorbed by both armor plates. As a result, an improved absorption of the detonation forces from the lateral direction and thus an overall higher protection of the vehicle by the mine protection is achieved.
- the invention is therefore based on the objective of creating a mine protection system which enables an improved absorption of detonation forces from detonating mines.
- this object is achieved in that the armor plates are supported by means of a support connection are in engagement with one another for mutual support in the event of detonation forces.
- the support connection of the mine protection enables the armor plates to be mutually supported when the detonation forces of detonating mines occur, in that the armor plates are in engagement with one another.
- detonation forces acting both laterally and from below can therefore be absorbed by both armor plates, so that the protection of the mine protection is improved overall.
- the detonation force acts on the first armor plate for example, then this can support at least part of this detonation force on the second armor plate and vice versa.
- the mutual support of the armor plates has an interactive effect. In this way, the detonation force can particularly advantageously be absorbed by the two armor plates regardless of its direction of action, so that the mine protection can withstand larger detonation forces overall and the protection is improved accordingly.
- the support connection is designed as a corner connection.
- the corner connection can result from the fact that the armor plates are in engagement with one another at an angle.
- the armor plates are in engagement with one another at their abutting edges, so that the support connection is configured accordingly as a corner connection.
- the support connection designed as a corner connection is modeled on the contour of the vehicle underbody at its corner areas, thus improved protection can also be achieved in the corner areas of the vehicle underbody.
- the support connection is designed as a toothing.
- the armor plates can be in engagement with one another in a structurally simple manner, so that mutual support can be ensured in the event of detonation forces. It can be particularly advantageous if the angled arrangement of the armor plates with respect to one another can also be realized by means of the toothing, in that the contour of the toothing is adapted accordingly.
- the arrangement of the mine protection on the vehicle it can be provided that it is arranged on the vehicle underbody in such a way that the toothing is arranged on the corner areas of the vehicle underbody and the corner areas are accordingly protected.
- a further advantageous embodiment of the invention provides that the armor plates are positively engaged with one another.
- the mutual form fit can enable the armor plates to be supported on each other in a structurally simple manner when detonation forces occur.
- the support connection it has also been found to be particularly advantageous if the support connection is designed such that the first armor plate can be supported in its normal direction relative to the second armor plate and the second armor plate can be supported in its normal direction relative to the first armor plate.
- the normal directions of an armor plate are orthogonal to the plane of the armor plate. Due to the mutual supportability of the armor plates in their normal direction, an improved absorption of both the detonation forces acting from below and the detonation forces acting from the side can be achieved.
- the armor plates each in their for Vehicle-directed normal direction can be supported against the respective other armor plate.
- the support connection has a first support profile arranged on the first armor plate and / or a second support profile arranged on the second armor plate.
- the support profile By means of the support profile, mutual support of the armor plates can be made possible in a structurally simple manner.
- the support profiles of both armor plates are designed to correspond to one another, so that the armor plates are in engagement by means of the support profiles.
- the support profile arranged on the first armor plate it can be particularly advantageous if the support profiles of both armor plates are designed to correspond to one another, so that the armor plates are in engagement by means of the support profiles.
- the support profile arranged on the first armor plate it can be particularly advantageous if the support profiles of both armor plates are designed to correspond to one another, so that the armor plates are in engagement by means of the support profiles.
- the support profile arranged on the first armor plate it can be particularly advantageous if the support profiles of both armor plates are designed to correspond to one another, so that the armor plates are in engagement by means of the support profiles.
- the support profile arranged on the first armor plate
- At least one support profile in particular both support profiles, is designed in one piece as part of the respective armor plate. This can lead to a higher protective effect of the mine protection, since the support profile, as an integral part of the respective armor plate, is directly materially connected to it. With this configuration, connections between the support profile and the respective armor plate, which weaken the mine protection, can be avoided in a simple manner.
- At least one support profile in particular both support profiles, is arranged on an end region, in particular on an end face, of the respective armor plate.
- This arrangement of at least one Support profile can bring advantages in terms of manufacturing technology, since the support profile can be arranged at the end regions with little effort.
- the support profile can be produced in a simple manner on the end regions of the respective armor plate.
- it can also advantageously result that when the support profile is arranged on the end region, material of the armor plate protruding beyond the support profile can be avoided. This can have a beneficial effect on the total weight of the mine protection.
- At least one support profile in particular both support profiles, has at least one support surface and one contact surface.
- the support surface can serve to support the respective armor plate against the contact surface of the respective other armor plate.
- the support surface of the first armor plate can support this against the contact surface of the second armor plate and the support surface of the second armor plate can support this against the contact surface of the first armor plate.
- the support surface of the first support profile is essentially flat against the contact surface of the second support profile and the support surface of the second support profile is essentially flat against the contact surface of the first support profile.
- the result is that the support surface of the respective armor plate rests against the contact surface of the respective other armor plate and vice versa.
- the mutual support can be achieved in a structurally simple manner by means of the support connection. It has been found to be particularly advantageous if the support surface and the contact surface of a support profile are different from one another. In this way, the protection of the mine protection can be increased further, in that the orientation of the support surface can be adapted according to the direction of action of the detonation forces that occur.
- the support surface can in particular advantageously be oriented in such a way that the armor plate can be supported in the direction of detonation forces occurring, in particular acting from below and / or acting from the side.
- the support surface of the support profile is oriented orthogonally to the effective direction of occurring detonation forces, such as a horizontally oriented support surface for supporting detonation forces acting from below and / or an inclined one Support surface for supporting laterally acting detonation forces.
- the support surface of the support profile of the first armor plate can be configured to correspond to the contact surface of the support profile of the second armor plate and accordingly the support surface of the support profile of the second armor plate to correspond to the contact surface of the support profile of the first armor plate .
- the support surface and the contact surface of a support profile lie in different planes, in particular in planes oriented obliquely to one another.
- at least one support surface of the first support profile and / or the second support profile runs parallel to the respective armor plate plane, while at least one contact surface of the first support profile and / or the second support profile is oriented parallel to the other armor plate plane .
- At least one support profile in particular both support profiles, has a second support surface and / or a second contact surface.
- a second support surface and / or a second contact surface By means of a second support surface and / or a second contact surface, the entire surface available for support can be enlarged in a structurally simple manner.
- the first and second support surfaces and / or the first and second contact surfaces of a support profile it is also possible for the first and second support surfaces and / or the first and second contact surfaces of a support profile to be arranged at an angle to one another. This enables the support to be made possible in a further direction, namely essentially in the orthogonal direction to the second support surface.
- first support surface and the second support surface of a support profile are arranged one behind the other in the normal direction of the respective armor plate, that is, along the thickness of the armor plate. It has proven useful if the first contact surface and the second contact surface of a support profile are arranged one behind the other in the normal direction of the respective armor plate, that is, along the thickness of the armor plate. It can be particularly advantageous if the second support surface and / or the second contact surface extends over a quarter to over three quarters of the respective armor plate thickness.
- At least one of the supporting surfaces, in particular the second supporting surface, of at least one supporting profile is designed in the manner of a bevel. This can essentially extend over the entire width of the armor plate. As a result, the largest possible support surface is made possible without great manufacturing effort.
- the support surface designed as a bevel can be formed on an outer edge of the armor plate. It is possible that the support surface designed as a bevel extends only over part of the Thickness of the armor plate, in particular over less than 80%, preferably over less than 60% and particularly preferably over less than 50%. It is possible for the support surface to be designed as a coherent surface.
- the second contact surface of at least one support profile is designed in the manner of a bevel and extends essentially over the entire width of the armor plate. This enables one armor plate to be supported via the support surface designed as a bevel in relation to the other armor plate via the corresponding contact surface designed as a bevel.

- At least one support profile in particular both support profiles, have at least one protruding support structure, in particular a tooth.
- At least one support profile in particular both support profiles, has alternately arranged support structures, in particular teeth, and recesses. Due to the alternately arranged support structures and recesses in the armor plates, these can be engaged in a structurally simple manner. It is possible here for the support structures of the respective armor plate to be received by the recesses of the respective other armor plate. It is particularly advantageous here if the support structures of the respective armor plate are designed to correspond to the recesses of the respective other armor plate. Furthermore, it can be particularly advantageous in this context that the arrangement of the armor plates relative to one another, via the design of the support structures and the recesses, in particular, their angular arrangement to one another can be determined. The alternately arranged support structures and recesses can also enable uniform mutual support of the armor plates. In this context, it is also possible that a form fit can be established between the two armor plates by means of the support structures and recesses.
- the height of the at least one support structure differs from the thickness of the respective armor plate.
- the support profile of an armor plate has the support structure with the first support surface in a first thickness region of the armor plate and the second support surface in a second thickness region of the armor plate.

- the height of the at least one support structure on an armor plate corresponds to at least 50%, preferably at least 75%, particularly preferably at least 90%, of the thickness of the armor plate. Due to the height of the support structure the strength of these can be adjusted, so that it can be ensured that the mutual support of the armor plates by means of the support structure can take place even with large acting detonation forces without the support structures being damaged.
- At least one armor plate is flat.
- the planar design also enables the mine protection to rest flat against the areas of the military vehicle to be protected, so that an improved protective effect of the mine protection is achieved.
- at least one armor plate is designed to correspond to the area of the vehicle underbody to be protected, such as the floor and / or the side walls, for example with regard to the dimensions.
- the armor plates are loosely or detachably in engagement with one another. This enables the armor plates to be supported against one another by means of the support connection when detonation forces occur. At the same time, this creates a modular mine contactor that can be exchanged.
- the armor plates are only loosely, that is, unscrewed and / or unwelded, in engagement with one another, since the mutual support of the armor plates is not hindered by fixed connecting means such as screws or welds.
- at least one armor plate is designed as a monoblock, in particular as a metallic monoblock.
- the monoblock is made of armor steel or a light metal, such as titanium, aluminum and / or an aluminum alloy, so that the total weight of the mine protection can be designed to be low.
- At least one armor plate has a slug connection and / or a hole for attaching the armor plate to the military vehicle by means of a bolt.
- the armor plate can be fastened and arranged on the vehicle in a structurally and manufacturing-technically simple manner by means of the slug connection and / or the bore.
- the fastening by means of the bolt is designed to be floating. In this case it is possible that when detonation forces act on the armor plate, in particular also in the event of possible deformation of the armor plates, the bolt only absorbs insignificant proportions of these and thus the bolt can be prevented from tearing off.
- the floating fastening of the bolt it is possible to be able to compensate for certain tolerances of the mine protection, in particular of the armor plates, as these can occur, for example, during manufacture. Furthermore, the floating fastening of the bolts can make it possible for them to be loaded only in one direction, in particular in the longitudinal direction, as a result of which the fastening can be increased overall. It has been found to be advantageous if the armor plates are arranged at an obtuse angle to one another. Angles between 90 and 180 degrees are considered to be obtuse angles.
- the armor plates are arranged at an obtuse angle between 90 and 180 degrees, preferably between 110 and 160 degrees and particularly preferably between 125 and 145 degrees, to one another. As a result, the supporting effect of the mine protection can be improved and thus the protective effect can be increased.
- the first armor plate is designed as a lower floor protection and the second armor plate is designed as a side wall protection.
- the armor plates are assigned as floor protection and as wall protection.
- a spacer element arranged flat on at least one armor plate for spacing the armor plate from the vehicle underbody of the military vehicle is proposed.
- the spacer element enables possible distances between the armor plate and the vehicle underbody to be compensated in a structurally simple manner.
- the distances can arise, for example, due to the design of the vehicle underbody, in particular if it protrudes between the floor and the side wall.
- the spacer element is also designed as a plate so that it can lie flat against the armor plate.
- particularly light materials are suitable for the spacer element, that is to say in particular materials of low density.
- the spacer element designed as a plate can extend on one side over a large part of the outer surface of the armor plate facing the spacer element, in particular over at least 60%, preferably over 80% of this outer surface.
- the spacer element can be designed as a separate component. This can simplify the assembly of the spacer element and the armor plate to be arranged thereon.
- the spacer element, in particular the thickness of the spacer element can be adapted to the respective application, in particular to the respective vehicle underbody, without adapting the armor plate being necessary.
- the spacer element has a honeycomb structure or a foam Has structure. In this way too, an excessive increase in the weight of the mine protection can be avoided.
- the vehicle floor can be designed as a trough, in particular as an armored trough.
- An advantageous embodiment of the vehicle underbody provides that at least one armor plate is arranged on the floor to absorb lower detonation forces and at least one armor plate is arranged on the side wall to absorb lateral detonation forces. It can be particularly advantageous if the armor plate arranged on the floor is designed in such a way that it can be supported against the armor plate arranged on the side wall and the armor plate arranged on the side wall is correspondingly attached to the armor plate Armor plate arranged on the ground can support.
- the mine protection can be designed as additional armor. This can increase the protection of the floor and the side walls. The floor and the side walls can form the support structure of the vehicle underbody, whereas the mine protection is arranged on the support structure.
- At least one armor plate In connection with the arrangement of the armor plate on the floor, it is possible for at least one armor plate to be arranged flat against the floor. Furthermore, in connection with the arrangement of the armor plate on the side wall, it is possible for at least one armor plate to be arranged flat against the side wall. It has also proven to be advantageous if the angle of the armor plates essentially corresponds to the angle between the bottom and the side wall to one another. Such a design of the mine protection means that the contour of the vehicle can essentially be retained. In addition, it is possible that the armor plates attached to the vehicle floor come to rest against the floor, whereby the protection of the mine protection can be further increased.
- At least one spacer element is arranged between at least one armor plate and the floor and / or the side wall for spacing the armor plate from the floor or from the side wall.
- the base protrudes from the side wall. As the base protrudes beyond the side wall, it is possible to weld the side wall to the base on both sides. Furthermore, it is possible that when detonation forces occur, in particular from an effective direction from below, the base can be supported against the side wall.
- the protrusion can preferably be between a quarter and four times, particularly preferably between half and twice the thickness of the base.
- the protrusion can preferably correspond to between a quarter and four times, particularly preferably between half and one time, the thickness of the spacer element.
- the armor plates each extend over a large part of the outer surface of the base and the side wall facing the armor surfaces.

- mine protection 1 shows a schematic representation of a military vehicle 100 with a mine protection 1 according to the invention.
- mine protection 1 serve to protect the military vehicle 100 from detonating mines 300, the vehicle 100 in particular from detonation forces acting from below and from the sides should be protected.
- the mine protection 1 is attached to a vehicle underbody 200, in particular the vehicle hull, of the military vehicle 100, in particular on the floor 201 and side walls 202 of the vehicle underbody 200.
- the floor 201 and the side walls 202 form a supporting structure of the vehicle underbody 200.
- the mine protection 1 is arranged flat on the supporting structure, that is to say the floor and the side walls 202.
- the bottom 201 and the side walls 202 offer protection against detonating mines 300, which is additionally increased by the mine protection 1.
- the mine protection 1 is designed as additional armor for the vehicle underbody 200.
- the mine protection 1 accordingly has a first armor plate 2 arranged on the floor 201 and a plurality of second armor plates 3 arranged on the side walls 202.
- the first armor plate 2 is correspondingly oriented horizontally in the illustration, the second armor plate 3 correspondingly oriented obliquely in the illustration, so that they are arranged at an angle to one another.
- the armor plate 2 extends essentially over the entire floor 201 of the vehicle 100. This enables protection from detonating mines 300 over the entire surface of the floor 201.
- the armor plates 3 extend essentially over the respective entire side wall 202 - this enables protection against detonating mines 300 over the entire surface of the side walls 202.
- the armor plates 2, 3 are designed as coherent flat plates.
- the armor plates 2, 3 have a substantially cuboid shape.
- the armor plates 2, 3 are also in engagement with one another by means of a support connection 4.
- the support connection 4 is here arranged in a corner region of the vehicle underbody 200, where the floor 201 and the side walls 202 of the vehicle 100 meet, with different positions also being possible.
- the support connection 4 enables the armor plates 2, 3 to be mutually supported. If, for example, a mine 300 detonates below the vehicle, the detonation force acts primarily in an effective direction W1, namely acting from below, on the vehicle underbody 200 and in particular on the floor 201.
- the first armor plate 2 arranged on the floor 201 accordingly absorbs these detonation forces in the effective direction W1 and can be supported against the second armor plates 3 by means of the support connection 4.
- the detonation forces act primarily in an effective direction W2, namely acting from the side on vehicle underbody 200 and in particular on side walls 202
- the direction of action W2 are correspondingly absorbed via the second armor plates 3 arranged on the side walls 202, the second armor plates 3 also being able to be supported against the first armor plate 2 by means of the support connection 4.

Rather, the armor plates 2, 3 can be supported against one another in different spatial directions. The result is that the armor plates 2, 3 can mutually support the detonation forces acting on the vehicle underbody 200 in essentially all effective directions W by means of the support connection 4.
- the military vehicle 100 to be protected is a tank, the use of the mine protection 1 according to the invention not being limited to such a tank. It is also possible to use the mine protection 1 to protect other military vehicles 100, such as in particular land vehicles, for example tracked vehicles or wheeled vehicles, from detonating mines 300. It is also conceivable that the vehicle 100 can be retrofitted by means of the mine protection 1 to reinforce the mine protection. It is particularly advantageous if the mine protection 1 has a modular design.

- the armor plates 2, 3 are also designed as flat plates, so that they are attached to the floor 201 and the side wall 202 of the vehicle underbody 200. In general, it is advisable to design the armor plates 2, 3 to correspond to the vehicle underbody 200, in particular with regard to the shape and the dimensions. If, for example, the side wall 202 were provided with a curvature, it is also possible to provide the corresponding armor plate 3 with a curvature so that the armor plates 2, 3 can come to rest against the areas of the vehicle underbody 200 to be protected. The armor plates 2, 3 thus essentially follow the course of the vehicle underbody 200.
- the armor plates 2, 3 according to FIG. 2 are accordingly arranged at an angle ⁇ to one another for this purpose, the angle ⁇ corresponding to the angle ⁇ between the bottom 201 and the side wall 202.
- the illustrated angle ⁇ is approximately 135 °, with angles ⁇ other than 135 °, in particular angles between 90 ° and 180 °, preferably between 120 ° and 150 °, also being suitable.
- Such obtuse angles a advantageously have the effect that when detonation forces impinge on the armor plates 2, 3, at least some of them can be deflected and the protection of the mine protection 1 can thus be increased.
- the armor plates 2, 3 are in engagement in the corner area of the vehicle underbody 200 by means of the support connection 4. The engagement here enables a form-fitting connection of the two armor plates 2, 3, so that they can be mutually supported when detonation forces occur.
- the armor plates 2, 3 each have a support profile 5, 6 formed on the end regions of the armor plates 2, 3.

- the armor plates 2, 3 can advantageously be assembled and disassembled more easily.
- the mine protection 1 is designed in a modular manner.
- the support connection 4 it is also conceivable to design the support connection 4 to be at least partially cohesively connected, for example by welding.
- a few welding points can be set which could materially connect the armor plates 2, 3 at the welded contact points without the possibility of mutual support being significantly impaired.
- the support surfaces 5.1 are oriented at an angle to the support surfaces 6.1, so that the armor plates 2, 3 can be supported in several directions of the room.
- the orientation of the support surfaces 5.1, 6.1 are oriented in accordance with the primary effective direction W1, W2 of the possible detonation forces. It has been found to be particularly advantageous if the support surfaces 5.1, 6.1 run parallel to the respective plate planes of the armor plates 2, 3.
- the contact surface 5.2, 6.2 the respective other armor plate 2, 3 are to be designed accordingly.
- FIGS. 4a and 4b show a second exemplary embodiment of a mine protection 1 according to the invention.
- the relationships described above result here too, so that in the following, in particular, the peculiarities of this embodiment of the mine protection 1 will be discussed.

- the support surfaces 6.1 and 6.3 of the second support profile 6 are oriented at an angle to one another.
- the first support profile 5 has the contact surfaces 5.2 and 5.3, which are likewise oriented correspondingly at an angle to one another.
- the angles between the support surfaces 6.1, 6.3 and between the contact surfaces 5.2, 5.3 are designed to be the same size so that when the armor plates 2, 3 are in engagement, the support surfaces 6.1, 6.3 of the second support profile 6 with the Contact surfaces 5.2, 5.3 of the first support profile 5 come to rest.
- the armor plate 3 can thereby be supported on the armor plate 2 in the event of detonation forces acting on the armor plate 3, in particular in the effective direction W2.
- the armor plates 2, 3 are supported as described below.
- the support surfaces 6.1, 6.3 enable the armor plate 3 to be supported against the armor plate 2.
- the detonation forces are absorbed proportionally by both armor plate 3 and armor plate 2, as a result of which the protection of anti-mine protection 1 can be increased overall.
- the support surface 5.1 enables a support against the armor plate 3 and thus the detonation forces can also be absorbed by the two armor plates 2, 3.
- the support surface 6.1 is oriented parallel to the plate plane of the armor plate 3.
- a support surface 6.1 oriented in this way has the advantage that the detonation forces acting on the armor plate 3 act on the armor plate 3 in the direction of action W2 orthogonally to the support surface 6.1, so that the armor plate 3 can be supported particularly effectively against the armor plate 2.
- the support surface 6.3 is oriented at an angle to the support surface 6.1. Different orientations of the support surfaces 6.1, 6.3 are also possible in this context and can be adapted accordingly for the application.
- FIG. 5b shows that the armor plates 2, 3, when these are correspondingly attached to the vehicle 100, in particular to its vehicle floor 200 , rest on the bottom 201 and the side wall 202.
- the floor 201 and the side wall 202 are completely covered by the armor plates 2, 3 and correspondingly protected from detonating mines 300.
- the corner area of the vehicle underbody 200 that is to say the area in which the floor 201 and the side wall 202 meet, is also protected by the mine protection 1. This gives from the fact that the support connection 4 is arranged in this corner area.
- the support profiles 5, 6 end with the outer surfaces of the armor plates 2, 3, as a result of which the contour of the military vehicle 100 is essentially retained.
- FIG. 5b A further function of the support surface is also shown in FIG. 5b
- the support surface 6.3 is arranged at an angle to the support surface 6.1.
- the support surface 6.3 is based on the contact surface
- the support surface 6.1 is supported against the contact surface 5.1.
- the support surfaces 6.1, 6.3 lie flat on the contact surfaces 5.1,
- FIG. 5 c it is shown that the first support surface 5.1 is oriented parallel to the plate plane of the first armor plate 2.
- the detonation forces acting on the armor plate 3 act in the effective direction W1 orthogonally to the support surface 5.1 on the armor plate 3, so that the first armor plate 2 is also particularly effective compared to the second armor plate 3 is supportable.
- different orientations of the support surface 5.1 are possible.
- the different design of the support profiles 5 and 6, see FIGS. 5b and 5c, is based on the fact that the additional support surface 6.3, which is oriented at an angle to the support surface 6.1, provides an improved support of the armor plate 3 compared to the Armor plate 2 is made possible. This can be particularly advantageous when the lateral areas of the vehicle 100 are particularly in need of protection.
- a different configuration of the support surfaces 5.1, 6.1, 6.3 is also possible here.
- FIG. 6a and 6b each show a partial illustration of the first exemplary embodiment of the mine protection 1 according to the invention, once without and once with a spacer element 14.
- the partial illustration in FIG. 6c corresponds to the partial illustration in FIG. characters added to clarify the following description.
- the floor 201 and the side wall 202 are arranged at an angle to one another, the floor 201 terminating with the side wall 202.
- the mine protection 1 can accordingly be arranged directly on the vehicle underbody 200 without the spacer element 14.
- the armor plate 2 is attached to the floor 201 and the armor plate 3 to the side wall 202.
- the armor plates 2, 3 lie flat on the outer surfaces of the vehicle underbody 200 and protect it accordingly.
- 6b shows a vehicle underbody 200, in which the floor 201 partially protrudes beyond the side wall 202.
- the mine protection 1 has the spacer element 14 which is arranged on the armor plate 3 and thus fills the distance between the armor plate 3 and the side wall 202.
- the armor plate 2 on the other hand, is fastened directly to the floor 201.
- the support surfaces 5.1, 6.1, 6.3 as well as the contact surface 5.2, 5.3, 6.2 can also come into contact with the side wall 202 in spite of the protrusion of the base 201 through the, in particular, flat, stand-off element 14.
- the end face of the side wall 202 strikes the floor 201 in such a way that a protrusion U results.
- the protrusion U of the base 201 beyond the side wall 202 enables a double-sided welding 18 of the side wall 202 to the base 201. This can increase the strength of the connection between the floor 201 and the sides 202, which leads to an improved protective effect of the vehicle underbody 200 against the effects of detonating mines 300.
- the width of the weld seam can roughly correspond to the protrusion U here.
- the protrusion U of the base 201 over the side wall 202 enables the detonation forces, in particular from the direction of action W1, to be absorbed to a greater extent by the base 201 and this is supported by the side wall 202. At least some of the detonation forces can therefore be supported on the side wall 202 via the base 201. This can also increase the protective effect of the vehicle underbody 200 against the effects of detonating mines 300.
- the protrusion U corresponds approximately to the thickness of the bottom 201.
- the armor plate 2 is arranged on the floor 201 in such a way that the end face of the floor 201 is flush with the contact surface 5.3. As a result, the armor plate 2 rests flat against the floor 201 in the region of the overhang U as well. Because of the protrusion U, a distance A results between the side wall 202 and the armor plate 3 to be arranged on this side wall 202. The distance A also increases with an increasing protrusion U.
- the spacer element 14 is arranged between the side wall 202 and the armor plate 3.
- the thickness of the spacer element 14 corresponds to the distance A, so that the spacer element 14 rests against both the side wall 202 and the armor plate 3.
- values between single and double the projection U have proven useful.
- the spacer element 14 is arranged flat on the side wall 202.
- the outer surface 17 of the spacer element 14 facing the armor plate 3 lies in a plane E with one of the abutting edges 16 of the floor 201. This enables the support profiles 5, 6 to be fully engaged in a form-fitting manner. To this extent, the spacer element 14 compensates for the protrusion U of the base 201 and is in this respect designed as a compensating element.
- the angle between the plane E and the floor 201 corresponds to the angle ⁇ between the floor 201 and the side wall 202.
- the angle ⁇ of the armor plates 2, 3 can be maintained, the angle ⁇ therefore also corresponds to the embodiment of Fig. 6b the angle ⁇ .
- the spacer element 14 is arranged in the assembled state of the mine protection 1 between the armor plate 3 and the side wall 202 of the vehicle underbody 200.
- the spacer element 14 is designed as a monoblock, with lightweight materials, that is to say materials low density, have proven advantageous here, such as aluminum and / or an aluminum alloy.
- the spacer element 14 has a honeycomb structure, that is to say a honeycomb structure.
- an armor plate 2, 3 of the mine protection 1 according to the invention is fastened to the vehicle underbody 200 by means of a bolt 13.
- the armor plate 2, 3 has a bore 12 for receiving the bolt 13, so that the bolt 13 is pushed through the armor plate 2, 3 and the vehicle underbody 200 and the armor plate 2, 3 by means of a counterpart 15 in the manner of a nut attached to the vehicle underbody 200.
- a slug connection 11 for fastening the armor plate 2, 3 to the vehicle underbody 200.
- the slug connection 11 is designed to receive a bolt 12, so that the armor plate 2, 3 can be screwed to the vehicle underbody 200 by means of this bolt 12.
- connection possibility through a slug connection 11 or through a bore 12 it is particularly advantageous in this context if the attachment of the armor plate 2, 3 is designed to be floating. This can prevent the bolts 13 used for fastening from being transversely stressed when detonation forces act on the armor plate 2, 3, so that these bolts 13 can be prevented from tearing off. It is also advantageous that when swimming Menden connection certain tolerances of the armor plates 2, 3, which may arise due to the selected manufacturing technology, can be compensated for during assembly.
