    535 649 If the armor ring consists of armor steel alloys, they have the disadvantage that at a high armor degree they have a high dead weight. This dead weight significantly increases the total weight of the vehicle. In particular in the case of combat vehicles or vehicles used for operational purposes, weight saving is of great importance. When it comes to air transport of combat vehicles, the weight savings of vehicles are to be considered.
    An additional requirement for armoring vehicles consists of a significant increase in passenger protection, as a result of constantly evolving armor-piercing ammunition and the threat of explosions, such as explosive charges in the form of IED (improvised explosive device).
    The task of the present invention is thus to provide an armor option, which ensures a high level of protection against weapons at the same time low dead weight and the possibility of modular armor.
    The above-mentioned problem is solved according to the invention with the features of claim 1, in that the component is substantially hemispherically designed.
    Advantageous developments of the present invention are described in the dependent claims 2 to 13.
    In a further embodiment, the above-mentioned task is solved in that the component is a component of the body components of the motor vehicle.
    Hemispherically designed component essentially refers to an elliptical section-shaped outer surface. In this case, a concave curvature extends over most of the total component. The benefits that result from this are partly an increase in the static ballistic performance of a vehicle armored with components according to the invention. Due to the hemispherical curvature, the critical hit situations for the ballistic protection against armor-piercing projectiles at a perpendicular angle (90 °) are largely avoided. An average shelling with an automatic weapon here results in a statistically average significantly more ricochets, so that the armor-piercing projectiles strike the surface of the armor component at an angle of less than 90 °. Consequently, 535,649 significantly ricochets occur and at the same plate thickness, an increased protective effect against armor-piercing projectiles results in comparison with an evenly designed armor plate.
    Another form of the increase in the protective effect is the increase against compressive load.
    This is done through an outwardly directed concave surface. As a result of a pressure wave, a flat-shaped armor component can be displaced into the inner space. Due to the substantially hemispherically shaped surface of the motor vehicle armor component, a buckling of the armor component is displaced into the interior of the vehicle at a higher pressure level. The previously described features increase the overall protective effect for vehicle passengers.
    The component is formed of an armored steel alloy. Armored steel alloys are sufficiently well known in the art and offer an extremely good range of uses for protection against both ballistic and explosive weapons. The armored steel alloy preferably has the alloying components: carbon, silicon, manganese, aluminum, copper, chromium, nickel, molybdenum, boron and / or tungsten. In this case, the hardenability of the armored steel alloy can be improved with, for example, the elements carbon, silicon and tungsten. A high hardness can be achieved, for example, with the elements carbon, silicon and tungsten setting. Tungsten in particular forms very hard carbides and increases the tensile strength, tensile strength and toughness of the armored steel alloy. In addition, the armor steel alloy exhibits a large amount of iron and molten impurities.
    The component is produced by thermoforming and die hardening. For the manufacture of a motor vehicle armor component, a method is proposed in which first a sheet of uncured armor steel with a plate thickness of preferably 5 mm to 150 mm is provided and the component is heated to a temperature above the Acg point temperature of the alloy before final forming.
    The component heated over the A03 is then brought to its final shape in a press tool, and at the same time hardens by lingering in the press tool.
    The component is consequently built into the vehicle for armament without further conversion steps. By transformation steps is meant here active design by 535 649, for example deep drawing, bending or embossing. A trimming along the edge or a separation of your final shaped components can be carried out after the hardening, however, this can also be avoided as a result of the previous cutting of the sheet, for example.
    For a further increase in the rigidity and protective effect of the armor steel component, it has a reinforcing structure. Through the reinforcement structure, a further stiffening of the component is achieved. This is particularly advantageous because only small additional costs arise and the microstructure is not adversely affected. In this case, the weight increases only to a small extent as the pressure loading performance increases. The reinforcing structure may be in the form of folds in the component itself. Furthermore, it is also conceivable to introduce seams in the component by a forming process. In a particularly preferred embodiment, the reinforcing structure is formed on an inside of the component. Furthermore, the reinforcement structure is connected to the component as an independent component. This offers the advantage that another material can be used for the reinforcement structure is for the component itself. Accordingly, the reinforcing structure can be optimally applied taking into account the weight ratios on the inside of the component to be manufactured.
    The reinforcing structure is provided in the form of curved edges in the component itself. Through the press hardening process, for example, the reinforcing structures can be produced directly in and together with the component. In this case, the component to be manufactured can be shaped particularly optimally when the protective effect is taken into account and at the same time low dead weight.
    The microstructure is not affected by the production of the hemispherical surface by integrated reinforcement structure. An external reinforcement structure would possibly lead to a microstructure transformation through a gluing process or a welding process.
    Preferably, the curved edges extend substantially the entire length and / or width of the component. This has the advantage that the bending stiffness of the component is significantly increased as a result of the curved edges running over the entire length or width of the component. This also increases the total stiffness of the component, for example also in the peripheral areas.
    Particularly preferably, the curved edges extend further in the longitudinal and / or transverse direction of the component. Due to the resulting geometric reinforcement structures, the component is particularly rigid against compressive loads from different directions. In a particularly preferred embodiment variant, an X-shaped section is formed over the entire component by the curved edges. The X-shaped section is characterized in particular by a large resistance to compressive loading. Furthermore, it enables a substantially hemispherically designed surface extension over the entire component, at the same time high rigidity, achieved by the curved edges. Preferably, the surface of the X-shaped section is concavely curved. It then forms the main part of the hemispherical curvature of the component.
    As a result of the X-shaped section, four sections are generated, the surfaces of which have a convex curvature. An advantage that results from this is the interaction between concave and convex surfaces, which also increases the rigidity of the component. In a further particularly preferred embodiment, the armored steel component is a component of a motor vehicle door. Due to the geometric design and the high resistance to compressive loading, the inventive armored steel component is particularly well suited to be integrated on an inside, for example in the form of an inner lining, in a vehicle door, or to form the cover plate on an outside. A further advantage which results from this is that the edge stiffness of the outer circumferential outer edge of the component is increased, which constitutes a weak point of the prior art in armored vehicles. In a preferred device variant, the curvature of the component is directed outwards with respect to the interior space of the vehicle. As a result of the substantially hemispherically designed surface of the armored component, a moment of resistance is thus increased against a compressive load acting from the outside against the space of the vehicle. Further advantages, features, characteristics and aspects of the present invention will become apparent from the following description, preferred embodiments upon reference to the schematic drawings. These serve to simplify the understanding of the invention. There: fi Figure 1 shows a first embodiment variant of a hemispherically curved component; fl gur2 a second embodiment variant of the component with reinforcement structure; Figure 3 shows a further embodiment variant with a reinforcement structure and Figure 4 a third embodiment variant with an X-shaped reinforcement structure.
    In the figures, the same reference numerals are used for the same or similar parts, whereby corresponding or comparable advantages are obtained, even when a repeated description is omitted for the sake of simplicity.
    Figure 1 shows a component 1 according to the invention in plan view, which is made of a steel plate 2. A side view of both the length and width of the component 1 is also shown.
    Figure 2 shows a component 1 according to the invention, which has a reinforcing structure 3. Component 1 is again shown in a plan view and in a side view over the length and over the width. The reinforcing structure 3 is in Figure 2 connected to the steel plate 2 as an independent component 4. The components are additionally arranged on an inside 5 of the steel plate 2. The reinforcing structure 3 has a substantially X-shape.
    Figure 3 shows another embodiment variant of a component 1 according to the invention with a reinforcing structure 3, wherein here the reinforcing structure 3 is designed running horizontally and vertically.
    Figure 4 shows a further embodiment of an armor steel component / armor steel component 1, which is manufactured from a steel sheet by means of thermoforming.
    In this case, the reinforcing structures are designed as curved edges 6, which 535 649 preferably extend over the entire length 7 and the entire width 8 of the component 1.
    The reinforcing structure is then substantially designed as an X-shaped section 9 over the entire component 1. The X-shaped section 9 then has a surface 10, which in plan view substantially forms the X-structure.
    Extending between the legs of the X-shaped section 9 are further sections 11. These further sections 11 also have surfaces 12, which extend between the legs of the X-shaped section 9. The surface of the X-shaped section 9 thereby has a substantially concave curvature. The surfaces 12 of the sections 11 have substantially convex shapes relative to the concave surface 10. In the sectional views A - A, B - B and C - C, the respective X-shaped sections 9 with associated surfaces 10 and the sections 11 with associated surfaces 12 are illustrated. 535 649 Reference numerals: 1- 2_ 3- 4- 5- 5- 7- g- 9- 10- 11- 12- component steel plate reinforcement structure independent component inside curved edge length width X-shaped section surface of 9 sections surface of 11
