Description

BESCHREIBUNG  DESCRIPTION
Schutzaufbau für ein gepanzertes Fahrzeug Protective structure for an armored vehicle
Die Erfindung betrifft einen Schutzaufbau für ein gepanzertes Fahrzeug oder Objekt, der mindestens in Teilbereichen außenseitig mit einer Grundstruktur des gepanzerten Fahrzeuges kraftschlüssig verbindbar ist. The invention relates to a protective structure for an armored vehicle or object, which is externally frictionally connectable at least in some areas with a basic structure of the armored vehicle.
Ein derartiger Schutzaufbau wird beispielsweise in der EP 2 195 601 B1 für den Turm eines Kampfpanzers beschrieben. Dabei dient die Grundstruktur des Turmes, bei der die Außenhaut aus Panzerstahi besteht, als Schutzzelle, insbesondere für die Besatzung des Kampfpanzers. Hingegen dient der an der Grundstruktur des Turmes zusätzlich angeordnete, Schutzelemente umfassende Schutzaufbau dem Schutz außenseitig an der Rahmenkonstruktion angeordneter Elektronikbaugruppen, Baugruppen für die Munitionszuführung sowie Baugruppen zur Turmsteuerung etc. Such a protective structure is described for example in EP 2 195 601 B1 for the tower of a main battle tank. Here, the basic structure of the tower, in which the outer skin of Panzerstahi is used as a protective cell, especially for the crew of the main battle tank. On the other hand, the protective structure, which is additionally arranged on the basic structure of the tower, serves to protect electronic assemblies arranged on the outside of the frame construction, assemblies for the ammunition feed, and assemblies for tower control, etc.
Als Material für den Schutzaufbau wird in der EP 2 195 601 B1 unter anderem dünn- oder dickschichtiges Verbundmaterial, insbesondere Keramikverbundmaterial, vorgeschlagen. Ein derartiges Verbundmaterial ist allerdings relativ kostenaufwendig. Außerdem lassen sich an einem derartigen Material in der Regel keine Bolzen, Ösen und dgl. zur außenseitigen Anordnung weiterer Baugruppen des Kampfpanzers befestigen. As a material for the protective structure, EP 2 195 601 B1 proposes inter alia thin or thick-layered composite material, in particular ceramic composite material. However, such a composite material is relatively expensive. In addition, can be attached to the outside of other assemblies of the main battle tank on such a material usually no bolts, eyelets and the like.
Aus der DE 102 57 942 A1 ist femer bekannt, zum Schutz gepanzerter Fahrzeuge gegen den Beschuss mit Hohlladungen modulartige Schutzelemente zu verwenden, die einen offenporigen Metallschaum enthalten. Hierzu wird der entsprechende offenporige Metallschaum in ein Metallgehäuse, beispielsweise aus Stahl, eingesetzt und das Gehäuse dann außenseitig an dem Kampfpanzer befestigt. From DE 102 57 942 A1 is also known to use to protect armored vehicles against the bombardment with shaped charges modular protection elements that contain an open-cell metal foam. For this purpose, the corresponding open-cell metal foam in a metal housing, for example made of steel, and the housing then attached to the outside of the main battle tank.
Nachteilig sind in diesem Fall die relativ kostenintensive Herstellung der einzelnen Schutzmodule sowie die Verbindung der einzelnen Module miteinander, um einen große- ren Wandbereich eines gepanzerten Fahrzeuges mit diesem Schutzaufbau zu versehen. A disadvantage in this case is the relatively cost-intensive production of the individual protection modules as well as the connection of the individual modules with one another in order to achieve a large wall area of an armored vehicle with this protective structure.
Der Erfindung liegt die Aufgabe zugrunde, einen Schutzaufbau für gepanzerte Fahrzeuge anzugeben, der einfach herstellbar und großflächig an dem Fahrzeug anbringbar ist sowie ein geringes Gewicht aufweist. The invention has for its object to provide a protective structure for armored vehicles, which is easy to manufacture and large-scale attachable to the vehicle and has a low weight.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche. This object is achieved by the features of claim 1. Further, particularly advantageous embodiments of the invention disclose the dependent claims.
Die Erfindung beruht im Wesentlichen auf dem Gedanken, für den Schutzaufbau mehrere fläche nförm ig ausgebildete Schutzelemente zu verwenden, die jeweils eine Metallschaum-Sandwichstruktur mit zwei Deckschichten und einem dazwischen angeordneten Schaumkern aufweisen. The invention is based essentially on the idea of using a plurality of surface-shaped protective elements for the protective structure, each having a metal foam sandwich structure with two cover layers and a foam core arranged therebetween.
Um einen sehr leichten Schutzaufbau zu erhalten, hat es sich als vorteilhaft erwiesen, wenn die Schutzelemente jeweils eine Sandwichstruktur aufweisen, deren Schaumkern und deren Deckschichten aus einer Aluminiumlegierung (Aluminiumschaumsandwich) bestehen (Aiu-Schaum). In order to obtain a very light protective structure, it has proved to be advantageous if the protective elements each have a sandwich structure whose foam core and its outer layers consist of an aluminum alloy (aluminum foam sandwich) (Aiu foam).
Um eine stabile Verbindung der Schutzelemente des Schutzaufbaus an der jeweiligen Grundstruktur des gepanzerten Fahrzeuges zu erhalten, sind vorzugsweise leistenförmige Verbindungselemente an der Grundstruktur angeordnet, mit denen die Schutzelemente fest und unlösbar miteinander verbunden sind, beispielsweise verschweißt. Dabei hat sich insbesondere bewährt, wenn die Verbindungsnähte in Längsrichtung einen wellenförmigen Verlauf aufweisen. Dadurch wird vermieden, dass die Kraft linear von den leistenför- migen Verbindungselementen, beispielsweise Metall-Leisten, in den Metall-Schaum bzw. Alu-Schaum einfließt, sondern über einen größeren Bereich. Der wellenförmige Verlauf der Schweißnaht verringert die Kerbeinwirkung und somit die Bruchgefahr. In order to obtain a stable connection of the protective elements of the protective structure to the respective basic structure of the armored vehicle, strip-shaped connecting elements are preferably arranged on the basic structure, with which the protective elements are fixedly and non-detachably connected to one another, for example welded. It has proven particularly useful if the connecting seams have a wave-shaped course in the longitudinal direction. This avoids that the force flows linearly from the strip-shaped connecting elements, for example metal strips, into the metal foam or aluminum foam, but over a larger area. The wave-shaped course of the weld reduces the notch effect and thus the risk of breakage.
Der jeweilige Schutzaufbau kann vorteilhafterweise offene oder auch geschlossene gehäuseförmige Teilbereiche umfassen, die jeweils aus einer Rahmenkonstruktion bestehen, wobei die Schutzelemente die Rahmenfelder ausfüllen. Um eine stabile Verbindung zwischen der Rahmenkonstruktion und den Schutzelementen auch im Belastungsfall sicherzustellen, hat es sich als vorteilhaft erwiesen, wenn die Schutzelemente und die ebenfalls aus Metall bestehenden Rahmenelemente (Träger) derart miteinander verbunden werden, dass beide Deckschichten der jeweiligen Sandwichstruktur mit dem entsprechenden Rahmenelement unlösbar sind. Auch in derartigen Fällen hat es sich bewährt, wenn die Verbindungsnähte in Längsrichtung einen wellenförmigen Verlauf aufweisen. The respective protective structure can advantageously comprise open or closed housing-shaped partial areas, each consisting of a frame construction, the protective elements filling the frame panels. In order to ensure a stable connection between the frame construction and the protective elements even in case of load, it has proved to be advantageous if the protective elements and the also made of metal frame members (carrier) are connected to each other such that both cover layers of the respective sandwich structure with the corresponding frame element are insoluble. Even in such cases, it has proven useful if the connecting seams have a wave-shaped course in the longitudinal direction.
Vorgeschlagen wird somit ein Schutzaufbau für ein gepanzertes Fahrzeug, der mindestens in Teilbereichen außenseitig mit einer Grundstruktur des gepanzerten Fahrzeuges kraftschiüssig verbindbar ist. Um einen Schutzaufbau für gepanzerte Fahrzeuge zu erhalten, der einfach herstellbar ist und ein geringes Gewicht aufweist, ist vorgesehen, für den Schutzaufbau mehrere flächenförmig ausgebildete Schutzelemente zu verwenden, die jeweils eine Metallschaum-Sandwichstruktur, insbesondere eine Aluminiumschaum- Sandwich-Struktur, aufweisen. Um zusätzliche Baugruppen des gepanzerten Fahrzeuges als auch weitere Schutzplatten zur Erhöhung des Schutzes (Einstellung verschiedener Schutzlevel) außenseitig an dem Schutzaufbau befestigen zu können, sind vorzugsweise mindestens ein Teil der Schutzelemente mit jeweils mindestens einem außenseitig vorstehenden, bolzenförmigen Noppen aus Metall versehen. Dabei lagern die bolzenförmigen Noppen jeweils in einer Bohrung des entsprechenden Schutzelementes und sind mit den gegenüberliegenden beiden Deckschichten der Metallschaum- Sandwichstruktur fest verbunden, insbesondere verschweißt. Diese Konstruktion erhöht die stabile Aufnahme der Baugruppen bzw. weiterer Schutzpiatten. It is therefore proposed a protective structure for an armored vehicle, which is on the outside at least in some areas with a basic structure of the armored vehicle kraftschiüssig connectable. In order to obtain a protective structure for armored vehicles, which is easy to manufacture and has a low weight, it is provided to use for the protective structure a plurality of surface-formed protective elements, each having a metal foam sandwich structure, in particular an aluminum foam sandwich structure. In order to attach additional components of the armored vehicle as well as other protective plates to increase the protection (setting different levels of protection) on the outside of the protective structure, preferably at least a portion of the protective elements are provided with at least one outside protruding, bolt-shaped knobs made of metal. In this case, the bolt-shaped knobs each store in a bore of the corresponding protective element and are firmly connected to the opposite two outer layers of the metal foam sandwich structure, in particular welded. This design increases the stable absorption of the modules or other Schutzpiatten.
Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus den folgenden, anhand von Figuren erläuterten Ausführungsbeispielen. Es zeigen: Further details and advantages of the invention will become apparent from the following, with reference to figures explained embodiments. Show it:
Fig. 1 eine perspektivische Ansicht der Grundstruktur des Turmes eines Kampfpanzers mit an der Grundstruktur angeordnetem erfindungsgemäßen Schutzaufbau, der mehrere getrennt angeordnete Aufbauteile umfasst; Figure 1 is a perspective view of the basic structure of the tower of a battle tank with arranged on the basic structure of the invention protection structure comprising a plurality of separately arranged body parts.
Fig. 2 die Ansicht auf einen Ausschnitt eines Schutzeiementes des in Fig. 1 dargestellten Schutzaufbaus schräg von oben und Fig. 2 is a view of a portion of a Schutzeiementes of the protective structure shown in Fig. 1 obliquely from above and
Fig. 3 eine vergrößerte Darstellung des in Fig. 2 mit III bezeichneten Bereiches als Seitenansicht (Längsschnitt). In Fig. 1 ist mit 1 die Grundstruktur des Turmes eines Kampfpanzers bezeichnet. Die Grundstruktur 1 besteht dabei im Wesentlichen aus einer Rahmenkonstruktion, wobei die Rahmenfelder durch Platten 2 aus Panzerstahl ausgefüllt sind. Diese Grundstruktur bildet gleichzeitig die Schutzzelle für die Besatzung (Kommandant, Richtschütze, Fahrer etc). An der Grundstruktur 1 des Turmes ist außenseitig ein Schutzaufbau 3 angeordnet. Dieser besteht aus mehreren, nicht notwendigerweise miteinander verbundenen Aufbauteilen 4-7, die dem Schutz außenseitig an der Grundstruktur 1 angeordneter Elektronikbaugruppen, Baugruppen für die Munitionszuführung sowie Baugruppen zur Turmsteuerung etc. (nicht dargestellt) dienen. Fig. 3 is an enlarged view of the designated in Fig. 2 with III area as a side view (longitudinal section). In Fig. 1, 1 denotes the basic structure of the tower of a main battle tank. The basic structure 1 consists essentially of a frame construction, wherein the frame panels are filled by plates 2 made of armored steel. This basic structure simultaneously forms the protective cell for the crew (commander, gunner, driver etc). On the basic structure 1 of the tower, a protective structure 3 is arranged on the outside. This consists of several, not necessarily interconnected body parts 4-7, which serve the protection on the outside of the basic structure 1 arranged electronic assemblies, assemblies for ammunition supply and assemblies for tower control, etc. (not shown).
Erfindungsgemäß werden für den Schutzaufbau 3 flächenförmig ausgebildete Schutzelemente 8 verwendet, die jeweils eine Metallschaum-Sandwichstruktur 9 (Fig. 2 und 3) mit zwei Deckschichten 10, 11 und einen dazwischen angeordneten Schaumkern 12 aufweisen (bei dem hier beschriebenen Ausführungsbeispiel wurde eine Sandwichstruktur verwendet, deren Schaumkern 12 und deren Deckschichten 10, 11 aus einer Aluminiumlegierung (Aluminiumschaumsandwiches) bestehen). According to the invention, surface-shaped protective elements 8 are used for the protective structure 3, each having a metal foam sandwich structure 9 (FIGS. 2 and 3) with two cover layers 10, 11 and a foam core 12 arranged therebetween (in the exemplary embodiment described here, a sandwich structure was used, whose foam core 12 and its cover layers 10, 11 consist of an aluminum alloy (aluminum foam sandwiches)).
Um eine stabile Verbindung der Schutzelemente 8 des Schutzaufbaus 3 an der Grundstruktur 1 des Turmes zu erhalten, sind leistenförmige Verbindungselemente 13 aus Metall an der Grundstruktur angeordnet. In diesen Metali-Leisten 13 ist eine nicht näher dargestellte Nut eingebracht, in die die Schaumplatten (Zellstruktur) bzw. Schutzelemente 8 eingesteckt werden. Die Leisten 13 als auch die Schutzeiemente 8 sind hierzu gegabelt. Die Schutzelemente 8 und die Metall-Leisten 13 werden dann unlösbar miteinander fest verbunden. Hierzu können die beiden Deckschichten 10, 11 der jeweiligen Sandwichstruktur 9 mit dem entsprechenden Verbindungselement 13 beispielsweise verschweißt werden. Alternative unlösbare Verbindungen sind Löten, insbesondere Hartlöten, Nieten, Kleben etc. Dabei weisen die Verbindungsnähte (z.B. Schweißnaht) 14 in Längsrichtung einen wellenförmigen Verlauf auf. In order to obtain a stable connection of the protective elements 8 of the protective structure 3 to the basic structure 1 of the tower, strip-shaped connecting elements 13 made of metal are arranged on the basic structure. In these metal strips 13 a not-shown groove is introduced, in which the foam plates (cell structure) or protective elements 8 are inserted. The strips 13 and the protective elements 8 are bifurcated for this purpose. The protective elements 8 and the metal strips 13 are then permanently connected to each other inseparably. For this purpose, the two cover layers 10, 11 of the respective sandwich structure 9 with the corresponding connecting element 13, for example, be welded. Alternative permanent joints are brazing, in particular brazing, riveting, gluing etc. In this case, the connecting seams (for example welded seam) 14 have a wavy course in the longitudinal direction.
Wie Fig. 1 entnehmbar ist, sind die Aufbauteile 4 und 5 des Schutzaufbaus 3 gehäuseförmig ausgebildet und bestehen jeweils aus einer Rahmenkonstruktion, wobei die Schutzelemente 8 die Rahmenfelder ausfüllen und mit Rahmenelementen 15 (Trägern) fest verbunden sind. Der Schutzaufbau 3 umfasst ein offenes und/oder ein geschlossenes gehäuseförmiges Aufbauteil 4, 5, das aus einer Rahmenkonstruktion be- steht, wobei die Schutzelemente 8 die Rahmenfelder ausfüllen. Die ebenfalls aus Metall bestehenden Rahmenelemente 15 sind mit den Schutzelementen 8 unlösbar verbunden (verschweißt) derart, dass beide Deckschichten (10, 11) der jeweiligen Sandwichstruktur (9) mit dem entsprechenden Rahmenelement (15) verschweißt sind. 1, the mounting parts 4 and 5 of the protective structure 3 are formed housing-shaped and each consist of a frame construction, wherein the protective elements 8 fill the frame fields and with frame members 15 (carriers) are firmly connected. The protective structure 3 comprises an open and / or a closed housing-shaped structural part 4, 5, which consists of a frame construction. stands, with the protective elements 8 fill the frame fields. The also made of metal frame members 15 are inextricably linked (welded) with the protective elements 8 such that both cover layers (10, 11) of the respective sandwich structure (9) with the corresponding frame member (15) are welded.
Auch die Rahmenelemente 15 sind bevorzugt gegabelt, um die Schutzelemente 8 durch Einstecken aufnehmen zu können. Die beiden Elemente 8, 15 werden ihrerseits ebenfalls fest und unlösbar, z.B. durch ein Verschweißen, miteinander verbunden. Auch diese Verbindungsnähte 14 weisen in Längsrichtung einen wellenförmigen Verlauf auf. The frame members 15 are preferably forked to accommodate the protection elements 8 by plugging. The two elements 8, 15, in turn, also become solid and insoluble, e.g. by welding, connected together. These connecting seams 14 also have a wavy course in the longitudinal direction.
Die in Fig. 1 dargestellten Schutzelemente 8 besitzen jeweils mehrere Bohrungen 16, in welche außenseitig vorstehende, bolzenförmige Noppen aus Metall eingeschweißt werden können. Mit diesen bolzenförmigen Noppen können dann zusätzliche Baugruppen (nicht dargestellt) aber auch weitere Panzerplatten etc. zur variablen Einstellung des notwendigen Schutzlevels, kraftschlüssig verbunden werden. The protective elements 8 shown in Fig. 1 each have a plurality of holes 16, in which externally projecting, bolt-shaped knobs made of metal can be welded. With these bolt-shaped knobs then additional assemblies (not shown) but also other armor plates, etc. for variable adjustment of the necessary level of protection, are positively connected.
Derartige bolzenförmige Noppen 17 sind in den Fig. 2 und 3 dargestellt. Sie lagern jeweils in einer Bohrung 16 des entsprechenden Schutzelementes 8 und sind jeweils mit den gegenüberliegenden Deckschichten 10, 11 der Metallschaum-Sandwichstruktur 9 unlösbar verbunden, beispielsweise verschweißt. Such bolt-shaped knobs 17 are shown in FIGS. 2 and 3. They each store in a bore 16 of the corresponding protective element 8 and are each inextricably connected to the opposite cover layers 10, 11 of the metal foam sandwich structure 9, for example, welded.
Die Erfindung ist selbstverständlich nicht auf das vorstehend beschriebene Ausführungsbeispiel beschränkt. Insbesondere muss der Schutzaufbau nicht zwingend aus mehreren getrennten Aufbauteilen bestehen, sondern kann, ähnlich wie dieses in dem eingangs erwähnten Dokument EP 2 195 601 B1 offenbart ist, auch aus einem zusammenhängenden Gebilde bestehen. Dabei werden dann die Platten 2 aus Panzerstahl der Grundstruktur 1 durch entsprechende Schutzelemente 8 des Schutzaufbaus 3 überdeckt, so dass die Schutzzelle zusätzlich gegen feindlichen Beschuss gesichert ist. Of course, the invention is not limited to the embodiment described above. In particular, the protective structure need not necessarily consist of several separate structural parts, but may, similarly as this is disclosed in the aforementioned document EP 2 195 601 B1, also consist of a coherent structure. In this case, the plates 2 made of armor steel of the basic structure 1 are covered by corresponding protective elements 8 of the protective structure 3, so that the protective cell is additionally secured against enemy bombardment.
