Description

Die Erfindung betrifft ein gepanzertes Fahrzeug, insbesondere einen Kampfpanzer, mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The invention relates to an armored vehicle, in particular a main battle tank, with the features of the preamble of claim 1.

Ein derartiges Fahrzeug ist in US 4 398 446 A beschrieben.Such a vehicle is in US 4,398,446 A. described.

Gepanzerte Fahrzeuge sind im Einsatz sehr häufig der Wirkung von Minen ausgesetzt. Wenn ein solches Fahrzeug auf eine Mine läuft, welche detoniert, wird ein außerordentlich starker Impuls auf die Bodenplatte der Fahrzeugwanne ausgeübt, der nicht nur zu einer kurzzeitigen sehr starken Ausbeulung der Bodenplatte nach innen führt, sondern bei dem auch die Impulsübertragung dazu führen kann, daß vor der Bodenplatte angeordnete Teile sich ebenfalls nach innen durchbiegen und eventuell abreißen und durch das Fahrzeug fliegen. Hierdurch ist die Besatzung aufs höchste gefährdet. Bei einer Minenschutzeinrichtung mit an der Außenseite der Bodenplatte angeordneten Verstärkungsblechen kommt der Verbindung dieser Verstärkungsbleche mit der Bodenplatte eine erhöhte Bedeutung zu. Die Bodenplatte der Fahrzeugwanne weist im allgemeinen in Querrichtung verlaufende Wannensicken auf, und der Erfindung liegt die Aufgabe zugrunde, diese Wannensicken mit zur Befestigung der Verstärkungsbleche an der Bodenplatte heranzuziehen.Armored vehicles are very often exposed to the action of mines in use. When such a vehicle runs on a mine which detonates, an extremely strong impulse is exerted on the floor pan of the vehicle trough, which not only leads to a short-term very strong bulging of the floor panel inwards, but in which also the impulse transmission can lead to Parts arranged in front of the bottom plate are also present bend inwards and possibly tear off and fly through the vehicle. This puts the crew at maximum risk. In a mine protection device with arranged on the outside of the bottom plate reinforcement plates of the connection of these reinforcing plates with the bottom plate of increased importance. The bottom plate of the vehicle trough generally has transversely extending troughs, and the invention has for its object to use these troughs with for fastening the reinforcing plates to the bottom plate.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den Merkmalen aus dem kennzeichnenden Teil des Patentanspruchs 1.The solution of this object is achieved according to the invention with the features of the characterizing part of patent claim. 1

Vorteilhafte Weiterbildungen des erfindungsgemäßen Fahrzeugs sind weiter unten und in den abhängigen Ansprüchen beschrieben.Advantageous developments of the vehicle according to the invention are described below and in the dependent claims.

Ein Grundgedanke der Erfindung besteht darin, in den Bauraum der Wannensicken Befestigungsgewinde einzusetzen, in welche Befestigungsschrauben einschraubbar sind, mittels derer das jeweilige Verstärkungsblech von unten oder auch vom Fahrzeuginnenraum aus mit der Bodenplatte verschraubt wird.A basic idea of the invention is to use fastening threads in the installation space of the trough beads, into which fastening screws can be screwed in, by means of which the respective reinforcing plate is screwed from below or else from the vehicle interior to the base plate.

Wie weiter unten anhand von Ausführungsbeispielen näher erläutert, läßt sich hierdurch eine gegen Minendetonationen sehr widerstandsfähige Befestigung der Verstärkungsbleche an der Bodenplatte erreichen.As explained in greater detail below on the basis of exemplary embodiments, this makes it possible to achieve a fastening of the reinforcing plates to the base plate which is very resistant to mine detonations.

Die Erfindung ist außer bei Kampfpanzern auch in vorteilhafter Weise einsetzbar bei Unterstützungsfahrzeugen, Bergepanzern, Pionierpanzern sowie Panzerschnellbrücken.The invention is except for main battle tanks also advantageously used in support vehicles, armored recovery vehicles, Pioneer tanks and fast armored bridges.

Fig. 1 zeigt in einer perspektivischen schematisierten Darstellung die von einem Kettenfahrwerk KF getragene Fahrzeugwanne FW eines Kampfpanzers bei abgenommenem Turm. Die Fahrzeugwanne FW ist mit einer Minenschutzeinrichtung versehen, indem die Bodenplatte 1 an ihrer Außenseite, also der Unterseite der Fahrzeugwanne FW, durch mehrere, sich jeweils über die volle Breite und einen Teil der Länge der Fahrzeugwanne erstreckende Verstärkungsbleche verstärkt ist, welche fest mit der Bodenplatte 1 verbunden sind. In den Fig. 2 bis 4 ist eines dieser Verstärkungsbleche 3 dargestellt, und seine Befestigung an der Bodenplatte 1 wird im folgenden erläutert. Fig. 1 shows a perspective schematic representation of the supported by a chain chassis KF vehicle pan FW a battle tank with the tower removed. The vehicle pan FW is provided with a mine protection device by the bottom plate 1 is reinforced on its outer side, ie the underside of the vehicle pan FW, by a plurality, in each case over the full width and part of the length of the vehicle trough extending reinforcing plates, which fixed to the bottom plate 1 are connected. In the Fig. 2 to 4 one of these reinforcing plates 3 is shown, and its attachment to the bottom plate 1 will be explained below.

Fig. 2 zeigt einen Teil der Bodenplatte 1 im Bereich der Enden der durch den Innenraum der Fahrzeugwanne FW geführten Drehstabfedern 9.1 und 9.2 des Fahrwerks KF. Dabei sind die Drehstabfedern 9.1 und 9.2 auf einem Teil ihrer Länge von Niederhaltern 9.3 umgeben, die fest mit der Bodenplatte 1 der Fahrzeugwanne verbunden sind. Die Bodenplatte 1 der Fahrzeugwanne FW weist in Querrichtung verlaufende Sicken 1.1 auf, die zur Befestigung des Verstärkungsblechs 3 an der Bodenplatte 1 herangezogen werden. Wie den Fig. 2 bis 4 zu entnehmen, ist die Wannensicke 1.1 an ihrer Außenseite nach unten durch ein Verschlußstück 2 abgeschlossen. Dieses Verschlußstück 2 ist in seinen Randbereichen durch Schweißnähte 7.3 und 7.4 mit der Bodenplatte verschweißt und in den so zwischen Verschlußstück und Wannensicke entstehenden Bauraum ist ein Befestigungsgewinde integriert, indem, wie Fig. 3 zu entnehmen, in eine Öffnung des Verschlußstückes 2 eine Befestigungshülse 4 eingesetzt und über eine Schweißnaht 7.2 fest mit dem Verschlußstück 2 verbunden ist. Diese Befestigungshülse 4 ist mit einer ersten Bohrung 4.1 versehen, die sich nach unten zur Außenseite hin öffnet und in die das Befestigungsgewinde eingeschnitten ist. In das unterhalb der Bodenplatte angeordnete Verstärkungsblech 3 ist eine durchgehende Verankerungshülse 5 eingesetzt und mit ihm über eine Schweißnaht 7.1 fest verbunden. In die Öffnung dieser Verankerungshülse 5 ist die Befestigungsschraube 6 derart eingesetzt, daß der Schraubenkopf an einem inneren Absatz der Verankerungshülse anliegt und dort festgehalten ist. Der Schraubenbolzen der Befestigungsschraube 6 wird in das Befestigungsgewinde der Hülse 4 eingeschraubt, so daß das Verstärkungsblech 3 an dieser Stelle fest mit der Bodenplatte 1 verbunden ist. Fig. 2 shows a part of the bottom plate 1 in the region of the ends of the guided through the interior of the vehicle pan FW torsion bars 9.1 and 9.2 of the chassis KF. The torsion springs 9.1 and 9.2 are surrounded on a part of their length by hold-downs 9.3, which are firmly connected to the bottom plate 1 of the vehicle pan. The bottom plate 1 of the vehicle pan FW has transversely extending beads 1.1, which are used for fastening the reinforcing plate 3 to the bottom plate 1. Like that Fig. 2 to 4 can be seen, the tubing bead 1.1 is closed on its outer side down by a closure piece 2. This closure piece 2 is welded in its edge regions by welds 7.3 and 7.4 with the bottom plate and in the resulting space between the closure piece and tub bead space a fastening thread is integrated by, as Fig. 3 can be seen, inserted into an opening of the closure piece 2, a fastening sleeve 4 and a weld 7.2 is firmly connected to the closure piece 2. This mounting sleeve 4 is provided with a first bore 4.1, which opens down to the outside and in which the fastening thread is cut. In the arranged below the bottom plate reinforcing plate 3, a continuous anchoring sleeve 5 is inserted and fixedly connected to it via a weld 7.1. In the opening of this anchoring sleeve 5, the fastening screw 6 is inserted such that the screw head bears against an inner shoulder of the anchoring sleeve and is held there. The bolt of the fastening screw 6 is screwed into the fastening thread of the sleeve 4, so that the reinforcing plate 3 is firmly connected to the base plate 1 at this point.

Bei der in Fig. 3 dargestellten Ausführungsform der Befestigung ist die Befestigungshülse 4 durch eine Öffnung in der Wannensicke 1.1 hindurchgeführt und an dieser Stelle durch eine Schweißnaht 7.5 mit der Wannensicke verschweißt. Weiterhin besitzt die Befestigungshülse 4 eine fluchtend zur Bohrung 4.1 angeordnete Gewindebohrung 4.2, die sich zur Innenseite der Bodenplatte 1 hin öffnet und in welche eine, in Fig. 3 nicht dargestellte Verschlußschraube einschraubbar ist.At the in Fig. 3 illustrated embodiment of the attachment, the mounting sleeve 4 is passed through an opening in the tubing bead 1.1 and welded at this point by a weld 7.5 with the well bead. Furthermore, the mounting sleeve 4 has an aligned with the bore 4.1 threaded bore 4.2, which opens to the inside of the bottom plate 1 and in which one, in Fig. 3 not shown screw plug is screwed.

Wie in Fig. 3' dargestellt, kann bei abgenommenem Verstärkungsblech 3 die untere Öffnung der Befestigungshülse 4 verschlossen werden, indem eine Schraube 6' eingeschraubt wird, die eine Verschlußkappe 6.1 trägt, welche sich mit ihrem Rand 6.2 dichtend an die Unterseite des Verschlußstückes 2 anlegt.As in Fig. 3 ' illustrated, the lower opening of the mounting sleeve 4 can be closed with removed reinforcing plate 3 by a screw 6 'is screwed, which carries a cap 6.1, which bears with its edge 6.2 sealingly against the underside of the closure piece 2.

Fig. 4 zeigt eine weitere Ausführungsform der Befestigung des Verstärkungsblechs 3 an der Bodenplatte 1. Es hat sich gezeigt, daß bei bestimmten Typen von Landminen, die einen sehr engen Wirkungsbereich haben, die bei der Detonation auftretenden Kräfte so groß sind, daß Schweißnähte allein nicht immer ausreichen, um ein Ausreißen der Befestigungselemente zu verhindern. Bei der in Fig. 4 dargestellten Ausführungsform der Befestigung des Verstärkungsblechs 3 an der Bodenplatte 1 sind deshalb noch besondere Vorkehrungen getroffen, um die Festigkeit der Verbindung zu erhöhen. In Fig. 4 sind alle mit Fig. 3 übereinstimmenden Bauteile mit der gleichen Bezugsziffer versehen. Der Unterschied gegenüber der Ausführungsform nach Fig. 3 betrifft vor allem die Ausbildung der Befestigungshülse 4'. Diese ist zwar nach wie vor mit dem Verschlußstück 2 durch die Schweißnaht 7.2 verbunden, ist aber an ihrem oberen Ende nicht mit der Sicke 1.1 verschweißt. Die Befestigungshülse 4' ist durch die Öffnung 1.2 der Sicke 1.1 hindurchgeführt, und zwar derart, daß sie mit ihrem inneren Ende 4.4' bündig zur Innenseite der Bodenplatte 1 am Kamm der Wannensicke 1.1 liegt. An der Innenseite der Wannensicke 1.1 liegt die Befestigungshülse 4' mit einem Ansatz 4.5' an. In die Gewindebohrung 4.2' der Befestigungshülse 4' ist die Verschlußschraube 8 unter Zwischenschaltung einer Scheibe 9 als Druckabsorber nunmehr derart eingeschraubt, daß, wie aus Fig. 4 abzulesen, die Befestigungshülse 4' fest mit der Bodenplatte 1 im Bereich der Wannensicke 1.1 verschraubt ist. Die Verschlußschraube 8 kann ein Trapezgewinde aufweisen und es hat sich gezeigt, daß dann die Widerstandskraft dieser Schraubverbindung im Falle einer Minendetonation größer ist als die einer Schweißverbindung. Der Innenraum 4.3' der Befestigungshülse 4' im Bereich zwischen den beiden Bohrungen 4.1' und 4.2' weist in radialer Richtung eine Erweiterung auf und der Durchmesser der sich zur Innenseite der Bodenplatte 1 hin öffnenden Gewindebohrung 4.2' ist kleiner als der Durchmesser der das Befestigungsgewinde tragenden Bohrung 4.1'. Fig. 4 shows a further embodiment of the attachment of the reinforcing plate 3 to the bottom plate 1. It has been found that in certain types of landmines, which have a very narrow range of action, the forces occurring in the detonation are so large that welds alone are not always sufficient to prevent tearing of the fasteners. At the in Fig. 4 illustrated embodiment of the attachment of the reinforcing plate 3 to the bottom plate 1 so special precautions are taken to increase the strength of the connection. In Fig. 4 are all with Fig. 3 matching components provided with the same reference numeral. The difference from the embodiment according to Fig. 3 especially concerns the formation of the fastening sleeve 4 '. Although this is still connected to the closure piece 2 through the weld 7.2, but is not welded at its upper end with the bead 1.1. The mounting sleeve 4 'is passed through the opening 1.2 of the bead 1.1, in such a way that it is flush with its inner end 4.4' to the inside of the bottom plate 1 on the comb the trough bead is 1.1. On the inside of the tubing bead 1.1 is the mounting sleeve 4 'with a shoulder 4.5' at. In the threaded hole 4.2 'of the mounting sleeve 4' is the screw plug 8 with the interposition of a disc 9 as a pressure absorber now screwed in such that, as from Fig. 4 read, the mounting sleeve 4 'is firmly bolted to the bottom plate 1 in the region of the tubing bead 1.1. The closure screw 8 may have a trapezoidal thread and it has been shown that then the resistance of this screw connection in the case of a mine detonation is greater than that of a welded joint. The inner space 4.3 'of the fastening sleeve 4' in the area between the two bores 4.1 'and 4.2' has an extension in the radial direction and the diameter of the threaded bore 4.2 'which opens towards the inside of the base plate 1 is smaller than the diameter of the fastening thread bearing Bore 4.1 '.

Die Befestigungsschraube 6 kann ein Rundgewinde aufweisen, was einen besonders widerstandsfähigen Sitz der Schraube sicherstellt.The fastening screw 6 may have a round thread, which ensures a particularly resistant seat of the screw.

Die Längen der Verschlußschraube 8 und der Befestigungsschraube 6 sind so bemessen, daß, wie aus Fig. 4 zu erkennen, die in die Gewindebohrung 4.2' eingeschraubte Verschlußschraube 8 das innere Ende der Befestigungsschraube 6 nicht berührt. Bei abgenommener Verstärkungsplatte 3 dient die Verschlußschraube 8 zum Verschließen der Öffnung in der Bodenplatte 1, und wie aus Fig. 4' zu erkennen, kann auch bei dieser Ausführungsform die Befestigungshülse 4' an ihrer Unterseite mittels einer Schraube 6' verschlossen werden, die eine Schutzkappe 6.1 trägt, welche sich mit ihrem Rand 6.2 dichtend an die Unterseite des Verschlußstückes 2 anlegt.The lengths of the screw plug 8 and the fastening screw 6 are dimensioned so that, as from Fig. 4 to recognize that screwed into the threaded hole 4.2 'screw plug 8 does not touch the inner end of the mounting screw 6. With removed reinforcing plate 3, the screw plug 8 serves to close the opening in the bottom plate 1, and as shown 4 ' can be seen in this embodiment, the mounting sleeve 4 'on its underside by means of a screw 6' are closed, which carries a protective cap 6.1, which bears with its edge 6.2 sealingly against the underside of the closure piece 2.
