Description

Die Erfindung betrifft eine Einrichtung zum automatischen Öffnen des Verschlusskeils an einer halbautomatischen Waffenanlage mit einer elektromechanischen Antriebsvorrichtung, die mit dem Verschlusskeil verbindbar ist und einen Elektromotor aufweist, dessen Abtriebswelle mit einem energiespeichernden Schwungrad fest verbunden ist, das über eine elektromagnetische Kupplung mit der Antriebswelle einer mechanischen Öffnungsvorrichtung verbunden ist und mit einer elektrischen Steuereinrichtung, durch welche bei geöffneter Kupplung der Elektromotor eingeschaltet wird und die ein Steuersignal erzeugt, welches die Kupplung für einen vorgegebenen Zeitraum in Eingriff bringt.The invention relates to a device for automatically opening the locking wedge on a semi-automatic weapon system with an electromechanical drive device which can be connected to the locking wedge and has an electric motor, the output shaft of which is firmly connected to an energy-storing flywheel which is connected to the drive shaft of a mechanical drive via an electromagnetic clutch Opening device is connected and with an electrical control device by which the electric motor is switched on when the clutch is open and which generates a control signal which engages the clutch for a predetermined period of time.

Eine derartige Einrichtung ist aus der US-A-2413241 bekannt. Die bekannte Einrichtung wird an Maschinenwaffen, beispielsweise bei Flugzeugen, eingesetzt und dient dazu, beim Blockieren der Waffe die notwendigen hohen Kräfte zum Öffnen des Verschlusses bereitzustellen.Such a device is known from US-A-2413241. The known device is used on machine guns, for example in aircraft, and is used to provide the necessary high forces for opening the breech when the gun is blocked.

In der DE-A-2 011237 ist eine Anordnung zum Spannen des Verschlusses und zum Auswerfen der Hülsen bei automatischen Feuerwaffen beschrieben, bei der zwischen dem Verschluss der Waffe und einem diesen antreibenden Elektromotor eine elektrisch betätigte Kupplung angeordnet ist, wobei die Kupplung einkuppelt, wenn der Elektromotor die Höchstdrehzahl erreicht hat.DE-A-2 011237 describes an arrangement for tensioning the breech and for ejecting the sleeves in automatic firearms, in which an electrically operated clutch is arranged between the breech of the weapon and an electric motor driving it, the clutch engaging when the electric motor has reached the maximum speed.

In der US-A-3 537 353 ist schliesslich ein elektronischer Schaltkreis zum automatischen Betätigen des Verschlusses bei einer Waffe mit grossem Kaliber beschrieben, der einen den Verschluss betätigenden Elektromotor aufgrund einer vorgegebenen Kombination von aussen erzeugten Steuersignalen ansteuert. Diese bekannte Vorrichtung ist relativ aufwendig und kompliziert aufgebaut und benötigt einen hohen Energieaufwand.Finally, US Pat. No. 3,537,353 describes an electronic circuit for automatically actuating the breech on a large-caliber weapon, which controls an electric motor that actuates the breech on the basis of a predetermined combination of externally generated control signals. This known device is relatively complex and complicated and requires a lot of energy.

Die der Erfindung zugrunde liegende Aufgabe geht von folgenden Voraussetzungen aus:

  • Bei Übungs- und Ausbildungsschiessen von Kampfpanzern wird die Panzerkanone oft mit einem Einstecklauf versehen, der es ermöglicht, kleinkalibrige und damit kostengünstige Munition zu verschiessen. Diese Munition (bis Kaliber 35 mm) verursacht an der Waffe jedoch keinen ausreichenden Rücklauf, so dass das automatische Öffnen des Verschlusses für den nächsten Ladevorgang entfällt.
The object on which the invention is based is based on the following conditions:
  • In the case of training and training shooting of battle tanks, the tank cannon is often equipped with a barrel which enables small-caliber and therefore inexpensive ammunition to be fired. However, this ammunition (up to 35 mm caliber) does not cause sufficient return on the weapon, so that the automatic opening of the breech for the next loading process is no longer necessary.

Dies hat zur Folge, dass nach jedem Schuss das Öffnen des Verschlusskeils vom Ladeschützen manuell durch Verdrehen der Öffnerwelle mittels eines Handhebens ausgeführt werden muss. Diese Aktion erweist sich vor allem beim Schiessen im Gelände aus der Fahrt als sehr schwierig ausführbar und ist relativ zeitaufwendig. Sie ist daher nicht annähernd vergleichbar mit dem zeitlichen und funktionellen Ablauf des Lade- und Schiessvorganges, wie er beispielsweise bei Verwendung von für diese Waffe normalkalibriger Munition (z.B. 120 mm) und dem entsprechenden automatischen Öffnen des Verschlusses infolge des Waffenrücklaufes auftritt, bei dem eine Schussfolge von maximal acht Schuss pro Minute gefordert ist.The consequence of this is that after each shot, the loading gun must be opened manually by the loader by turning the opening shaft by means of a hand lift. This action proves to be very difficult to carry out, especially when shooting off-road, and is relatively time-consuming. It is therefore not nearly comparable with the timing and functional sequence of the loading and shooting process, as occurs, for example, when using ammunition of normal caliber for this weapon (e.g. 120 mm) and the corresponding automatic opening of the breech as a result of the weapon return, in which a firing sequence occurs of eight shots per minute is required.

Um dieser Forderung in etwa gerecht zu werden, ist es erforderlich, auch bei Verwendung eines Einstecklaufes und der entsprechend kleinkalibrigen Munition, ein automatisches Öffnen des Verschlusskeiles, unabhängig vom Ladeschützen und in einem bestimmten zeitlichen Ablauf wie beim Schuss mit Originalmunition zu erreichen.In order to roughly meet this requirement, it is necessary, even when using a barrel and the correspondingly small-caliber ammunition, to automatically open the locking wedge, regardless of the loader and in a certain time sequence as when firing with original ammunition.

Eine Simulation des Rücklaufes der Waffe zur Auslösung des normalen automatischen Öffnungsvorganges für den Verschlusskeil ist aufgrund der hierzu benötigten hohen Energie ohne erheblichen technischen Aufwand nicht darstellbar.A simulation of the return of the weapon to trigger the normal automatic opening process for the locking wedge is not possible without considerable technical effort due to the high energy required for this.

Die der Erfindung zugrunde liegende Aufgabe bestand demnach darin, eine Einrichtung zum automatischen Öffnen des Verschlusskeils der eingangs erwähnten Art derart auszugestalten, dass sie mit geringem Energieaufwand beim Ausbildungsschiessen mit Einstecklauf eine Beladung der Waffe unter realistischen Bedingungen ermöglicht. Die Einrichtung sollte dabei so konzipiert sein, dass sie trotz ihres einfachen Aufbaus eine hohe Funktionssicherheit gewährleistet und insbesondere den beim Ausbildungsschiessen erhöhten Sicherheitsanforderungen genügt, so dass der Öffnungsvorgang nur ausgelöst wird, wenn wirklich ein Schuss abgefeuert wurde.The object underlying the invention was therefore to design a device for automatically opening the locking wedge of the type mentioned at the outset in such a way that it enables the weapon to be loaded under realistic conditions with little energy expenditure during training shooting with a plug-in barrel. The device should be designed in such a way that, despite its simple structure, it guarantees a high level of functional safety and in particular meets the increased safety requirements during training shooting, so that the opening process is only triggered when a shot has actually been fired.

Die Lösung dieser Aufgabe geschieht erfindungsgemäss mit den Merkmalen des Patentanspruchs 1.This object is achieved according to the invention with the features of patent claim 1.

Vorteilhafte Ausführungsformen der erfindungsgemässen Einrichtung sind in den Unteransprüchen beschrieben.Advantageous embodiments of the device according to the invention are described in the subclaims.

Die Montage der erfindungsgemässen Einrichtung kann ohne grossen technischen Aufwand vom Bedienungspersonal der Waffenanlage durchgeführt werden, ohne dass ein technischer Eingriff in das Waffensystem notwendig wird.The installation of the device according to the invention can be carried out by the operating personnel of the weapon system without great technical effort, without a technical intervention in the weapon system being necessary.

Im folgenden wird anhand der beigefügten Zeichnungen ein Ausführungsbeispiel für eine erfindungsgemässe Einrichtung näher erläutert.An exemplary embodiment of a device according to the invention is explained in more detail below with reference to the accompanying drawings.

In den Zeichnungen zeigen:

  • Fig. 1 in einer schematischen parallelperspektivischen Darstellung eine am Bodenstück einer Waffe angeordnete Einrichtung zum automatischen Öffnen des Verschlusskeils nach der Erfindung,
  • Fig. 2 ein Blockschaltbild für eine bei einer Einrichtung nach Fig. 1 verwendbare elektronische Steuereinrichtung.
The drawings show:
  • 1 is a schematic parallel perspective view of a device arranged on the base of a weapon for automatically opening the locking wedge according to the invention,
  • FIG. 2 shows a block diagram for an electronic control device that can be used in a device according to FIG. 1.

Bei der in Fig. 1 dargestellten Einrichtung ist am Bodenstück 11 der Waffe eine elektromechanische Antriebsvorrichtung angeordnet, die einen Elektromotor 1 aufweist, an dessen Abtriebswelle ein Schwungrad 2 befestigt ist und die über eine elektromagnetische Reibkupplung 3, ein Riemengetriebe 4, ein Untersetzungsgetriebe mit Drehrichtungsumkehr 5, eine elektromagnetische Zahnkupplung 6 sowie ein Kettengetriebe 7 mit einer Öffnerwelle 8 verbunden ist, an deren Ende ein hakenartiger Öffnerhebel 9 angeordnet ist. Der Schwenkbereich der Öffnerwelle 8 beträgt etwa 100°. Der Öffnerhebel 9 bewegt beim Verschwenken der Öffnerwelle 8 den Verschlusskeil 10 in der durch Pfeile angedeuteten Richtung in die Öffnungsstellung.In the device shown in FIG. 1, an electromechanical drive device is arranged on the base piece 11 of the weapon, which has an electric motor 1, on the output shaft of which a flywheel 2 is fastened and which via an electromagnetic friction clutch 3, a belt transmission 4, a reduction gear with reversal of direction of rotation 5 , an electromagnetic tooth coupling 6 and a chain transmission 7 is connected to an opening shaft 8, at the end of which a hook-like opening lever 9 is arranged. The swivel range of the opening shaft 8 is approximately 100 °. The opening lever 9 moves when swung ken the opening shaft 8, the locking wedge 10 in the direction indicated by arrows in the open position.

Die Ansteuerung des Elektromotors 1 sowie der beiden elektromagnetischen Kupplungen 3 und 6, die handelsüblicher Bauart sein können, erfolgt von einer in Fig. 1 als «Steuerelektronik» bezeichneten Steuereinrichtung, deren Einzelheiten in Fig. 2 dargestellt sind. Diese Steuereinrichtung weist ein dreifaches UND-Gatter 12 auf. Den Eingängen dieses UND-Gatters 12 werden nachfolgende elektrische Signale zugeführt. Ein von einer Vorrichtung 13 ausgehendes Signal, das angibt, ob die «Nenndrehzahl» des Schwungrades 2 erreicht ist. Diese Vorrichtung 13 kann beispielsweise ein handelsüblicher Tachogenerator sein, der in in Fig. 1 nicht eigens dargestellter Weise mit dem Schwungrad 2 gekoppelt ist.The control of the electric motor 1 and of the two electromagnetic clutches 3 and 6, which can be of a commercially available type, is carried out by a control device designated as “control electronics” in FIG. 1, the details of which are shown in FIG. 2. This control device has a triple AND gate 12. The following electrical signals are fed to the inputs of this AND gate 12. A signal emanating from a device 13, which indicates whether the “nominal speed” of the flywheel 2 has been reached. This device 13 can be, for example, a commercially available tachometer generator which is coupled to the flywheel 2 in a manner not specifically shown in FIG. 1.

Das Erreichen der Nenndrehzahl wird gleichzeitig durch eine Signallampe 14 angezeigt. Weiterhin wird dem UND-Gatter 12 von einem Impulsgeber 15 aus ein Signal zugeführt, welches angibt, ob ein Abfeuerimpuls vorliegt. Der Impulsgeber 15 wird dabei angesteuert durch das elektrische Abfeuersignal, das von einem Tastschalter 19 aus erzeugt wird, der in nicht eigens dargestellter Weise mit dem üblichen elektrischen «Bordnetz» des Kampfpanzers verbunden ist. Das vom Tastschalter 19 ausgehende Signal wird einerseits dem Impulsgeber 15 und andererseits über die mit «zur Kanone» bezeichnete Leitung der Abfeuervorrichtung zugeführt.A signal lamp 14 simultaneously indicates that the nominal speed has been reached. Furthermore, a signal is supplied to the AND gate 12 from a pulse generator 15, which indicates whether a firing pulse is present. The pulse generator 15 is controlled by the electrical firing signal, which is generated by a pushbutton switch 19, which is connected in a manner not shown to the usual electrical «electrical system» of the main battle tank. The signal emanating from the push button switch 19 is fed to the pulse generator 15 on the one hand and to the firing device on the other hand via the line labeled “to the cannon”.

Schliesslich wird von einer Vorrichtung 16 aus, die mit «Sensor» bezeichnet ist, dem UND-Gatter 12 ein drittes Signal zugeführt, das angibt, ob tatsächlich ein Abfeuervorgang stattfindet. Die Vorrichtung 16 enthält einen üblichen Impulsgeber, der von einem Sensor aus angesteuert wird, der den tatsächlichen Abfeuervorgang registriert. Ein solcher Sensor kann beispielsweise ein üblicher Endschalter sein, der in nicht eigens dargestellter Weise am Bodenstück 11 der Waffe angeordnet ist und durch den Rücklauf der Waffe betätigt wird. Es kann als Sensor aber auch ein piezoelektrischer Beschleunigungsgeber bekannter Bauart verwendet werden, der ebenfalls in nicht dargestellter Weise an einer geeigneten Stelle der Waffe angeordnet ist und beispielsweise auf den beim Abfeuervorgang erzeugten Körperschall reagiert.Finally, from a device 16, which is labeled “sensor”, a third signal is supplied to the AND gate 12, which indicates whether a firing process is actually taking place. The device 16 contains a conventional pulse generator which is controlled by a sensor which registers the actual firing process. Such a sensor can be, for example, a conventional limit switch, which is arranged on the base piece 11 of the weapon in a manner not specifically shown and is actuated by the return of the weapon. However, a piezoelectric accelerometer of a known type can also be used as a sensor, which is also arranged in a manner not shown at a suitable location on the weapon and, for example, reacts to the structure-borne noise generated during the firing process.

Wenn alle diese drei Signale am UND-Gatter 12 anliegen, wird von diesem ein Steuersignal an einen ersten Impulsgeber 17 abgegeben, der seinerseits das Steuersignal zur Ansteuerung der elektromagnetischen Kupplungen 3 und 6 abgibt. Gleichzeitig wird der Elektromotor 1 ausgeschaltet. Die abfallende Flanke des vom ersten Impulsgeber 17 abgegebenen Signals steuert einen zweiten Impulsgeber 18, dessen Ausgangssignal den Elektromotor 1 wieder einschaltet.If all of these three signals are present at the AND gate 12, a control signal is emitted from the latter to a first pulse generator 17, which in turn emits the control signal for actuating the electromagnetic clutches 3 and 6. At the same time, the electric motor 1 is switched off. The falling edge of the signal emitted by the first pulse generator 17 controls a second pulse generator 18, the output signal of which switches the electric motor 1 on again.

Die Funktionsweise der anhand der Fig. 1 und 2 beschriebenen Einrichtung ist folgende:The operation of the device described with reference to Figures 1 and 2 is as follows:

Zunächst wird der beispielsweise an das Bordnetz des Kampfpanzers angeschlossene Elektromotor 1 eingeschaltet und bringt das Schwungrad 2 auf die geforderte Nenndrehzahl. Die elektromagnetischen Kupplungen 3 und 6 sind nicht im Eingriff. Der Verschlusskeil 10 wird erstmalig vom Ladeschützen per Handhebel über die Öffnerwelle 8 geöffnet. Die Waffe wird geladen und der Verschlusskeil 10 schliesst automatisch über den in der Waffe integrierten, nicht eigens dargestellten Schliessermechanismus. Nun wird die Waffe abgefeuert. Sobald die vom Abfeuerimpuls und vom Abfeuervorgang herrührenden Signale zusammen mit dem Signal über die erreichte Nenndrehzahl am UND-Gatter 12 anliegen, gibt die Steuereinrichtung das Steuersignal an die beiden elektromagnetischen Kupplungen 3 und 6, die gleichzeitig über einen vorgegebenen Zeitraum bzw. einen vorgegebenen Weg des Verschlusskeiles 10 in Eingriff gebracht werden, wodurch Schwungrad 2 und Öffnerwelle 8 miteinander verbunden werden. Dabei wird die hohe Drehzahl des Elektromotors 1 über die Untersetzungsgetriebe 4, 5 und 7 in eine langsam verlaufende Drehbewegung von ca. 100° Drehwinkel umgewandelt. Kurz vor dem Erreichen der Endstellung der Öffnerwelle 8 bzw. des Verschlusskeils 10, werden die beiden elektromagnetischen Kupplungen 3 und 6 wieder getrennt und gleichzeitig wird vom Impulsgeber 18 aus der Elektromotor 1 wieder eingeschaltet. Dieser bringt das nicht ganz zum Stillstand gekommene Schwungrad 2 wieder auf Nenndrehzahl. Die Waffe wird inzwischen wieder geladen, der Verschlusskeil schliesst automatisch und die Waffe wird wieder abgefeuert.First, the electric motor 1, for example connected to the on-board network of the main battle tank, is switched on and brings the flywheel 2 to the required nominal speed. The electromagnetic clutches 3 and 6 are not in engagement. The locking wedge 10 is opened for the first time by the loader by hand lever via the opening shaft 8. The weapon is loaded and the locking wedge 10 closes automatically via the closing mechanism, not specifically shown, integrated in the weapon. Now the gun is fired. As soon as the signals originating from the firing pulse and from the firing process are present together with the signal about the nominal speed reached at the AND gate 12, the control device gives the control signal to the two electromagnetic clutches 3 and 6, which simultaneously over a predetermined period or a predetermined way of Locking wedge 10 are brought into engagement, whereby the flywheel 2 and the opening shaft 8 are connected to one another. The high speed of the electric motor 1 is converted via the reduction gears 4, 5 and 7 into a slowly rotating movement of approximately 100 ° rotation angle. Shortly before reaching the end position of the opening shaft 8 or the locking wedge 10, the two electromagnetic clutches 3 and 6 are separated again and at the same time the electric motor 1 is switched on again by the pulse generator 18. This brings flywheel 2, which has not come to a complete standstill, back to nominal speed. The weapon is now reloaded, the locking wedge closes automatically and the weapon is fired again.
