Description

Die Erfindung beschäftigt sich mit einem Schnellstopp für eine insbesondere fremd angetriebene Waffe.The invention deals with a quick stop for a particular foreign-powered weapon.

Aus der EP 1 767 891 A1 ist eine Vorrichtung zum Laden einer Maschinenkanone bekannt, die über einen Steuerkörper in der Ebene der Rohrseelenachse verfügt. Der zwei Steuerkurven tragende Steuerkörper ist dabei um das Waffengehäuse im Bereich der Rohraufnahme koaxial gelagert. Eine der beiden Steuerkurven ist mantelseitig, die andere stirnseitig am Steuerkörper eingebunden. Die mantelseitige Steuerkurve dient zur geradlinigen Zuführung des Verschlusses, die andere zur Verschlussverriegelung.From the EP 1 767 891 A1 a device for loading a machine gun is known, which has a control body in the plane of the tube axis. The two control cams supporting control body is mounted coaxially around the weapon housing in the region of the pipe receiving. One of the two cams is on the shell side, the other integrated on the front side of the control body. The shell-side control cam is used for straight-line feeding of the closure, the other for locking the lock.

Da Verschlussbewegungen bei einem Fremdantrieb unabhängig vom Gasdruck im Waffenrohr ablaufen, muss im Fall eines Anzündversagers (nach Zufuhr der Anzündenergie brennt die Treibladung in der Patrone nicht ab) bzw. Spätzünders (hier brennt die Treibladung mit deutlichem Zeitverzug ab) das Öffnen des Verschlusses verhindert werden. Dazu wird in der Regel der Gasdruck oder der Waffenlauf selbst als Indiz für einen ordnungsgemäßen Abbrand detektiert. Fehlt diese Information, muss ein so genannter Schnellstopp ausgelöst und das Öffnen des Verschlusses verhindert werden.Since shutter movements occur in a foreign drive regardless of the gas pressure in the barrel, must in the case of Anzündversagers (after supply of the ignition energy the propellant charge in the cartridge does not burn off) or retarded (here the propellant burns off with a significant delay), the opening of the closure can be prevented , For this purpose, the gas pressure or the weapon barrel itself is usually detected as an indication of proper burnup. If this information is missing, a so-called quick stop must be triggered and the opening of the closure prevented.

Durch die Massenkräfte beim Abbremsen des Fremdantriebes, um das Öffnen zu verhindern, entstehen insbesondere bei höheren Kadenzen hohe Belastungen in bzw. an den Elementen des Antriebsstranges.Due to the inertia forces during braking of the external drive to prevent the opening, high loads occur in or at the elements of the drive train, especially at higher cadences.

Mit der Problematik eines so genannten Schnellstopps bei fremd angetriebenen Waffen beschäftigt sich die nicht vorveröffentlichte DE 10 2007 048 470.6 . Der Schnellstopp wird stetig eingelegt und im Falle eines ordnungsgemäßen Schusses wieder ausgesteuert. Im Falle eines Zündversagers läuft ein Mittel, welches mit dem Waffenrücklauf funktional verbunden ist, auf den Schnellstopp auf, die Antriebsbewegung wird gestoppt, das Entriegeln des Verschlusses unterbleibt zumindest für eine vorgebbare Zeit.With the problem of a so-called quick stop in foreign-powered weapons deals with the non-pre-published DE 10 2007 048 470.6 , The quick stop is continuously inserted and controlled again in the case of a proper shot. In the event of a Zündversagers runs a means which is functionally connected to the weapon return on the quick stop, the drive movement is stopped, the unlocking of the closure is omitted at least for a predetermined time.

Aus der DE 30 21 200 C2 ist ein Schutzsystem gegen verspätetes Losgehen oder Nachzünden bekannt. Die Waffe ist neben einem Fühler zum Erfassen eines Rückstoßes mit einem Schnellstopp ausgerüstet, der zum Anhalten eines sich normalerweise kontinuierlich bewegenden Kettenteils und damit zum Stillsetzen der Bewegung des Verschlusses in eine bezüglich des Kettenteils eingerückte Position bringbar ist. Eine auf den Fühler ansprechende Verriegelungsvorrichtung steuert die Bewegung der Stoppvorrichtung zwischen der eingerückten Position, in welcher das Kettenteil angehalten wird, und einer ausgerückten Position, in der die Bewegung des Kettenteils ansonsten nicht behindert wird. Das Schutzsystem weist zwei mit dem Kettenteil verbundene Glieder auf, ein Hauptglied sowie ein Sicherheitsglied, sowie eine Abzugsstange, die von einem Hubmagneten gesteuert wird, und eine Rückstoßschubstange. Die Rückstoßschubstange dient zum Freisetzen eines Rückstoßklinkenriegels, wenn der Schuss gebrochen ist, die Abzugsstange zum Unterstellen des Sicherheitsgliedes beim Verriegeln der Waffe und Freigeben, wenn die Munition richtig abgefeuert ist. Für ein späteres Stillsetzen der Waffe greift die Abzugsstange am Hauptglied an, da der Hubmagnet abgeschaltet ist. Ein derartiger, elektrisch gesteuerter Hubmagnet ist jedoch insbesondere in Sicherheitseinrichtungen dieser Art unerwünscht, da selber störanfällig. Ein möglicher Materialbruch der Stangen macht die Sicherheitseinrichtung zudem nicht funktionssicher. Die gesamte Einheit ist zudem konstruktiv sehr aufwändig.From the DE 30 21 200 C2 is a protection system against late start or Nachzünden known. The weapon is equipped with a quick stop next to a sensor for detecting a recoil, which can be brought to stop a normally continuously moving chain part and thus to stop the movement of the shutter in an engaged relative to the chain part position. A locking device responsive to the sensor controls the movement of the stop between the engaged position in which the chain member is stopped and a disengaged position in which the movement of the chain member is otherwise unobstructed. The protection system includes two links connected to the chain member, a main link and a safety link, and a trigger bar controlled by a solenoid and a recoil pusher bar. The recoil push rod is for releasing a recoil latch when the shot is broken, the trigger bar for placing the safety member in place when locking the weapon, and releasing when the ammunition is properly fired. For a later shutdown of the weapon, the trigger rod engages the main member, since the solenoid is turned off. However, such an electrically controlled solenoid is undesirable in particular in safety devices of this type, since itself prone to failure. A possible material breakage of the rods also makes the safety device not functionally reliable. The entire unit is also structurally very complex.

Die DE 32 18 550 C2 offenbart eine Blockiereinrichtung für eine Maschinenkanone mit einem fremd angetriebenen Verschlussantrieb. Hierbei dient eine aus der Schussentwicklung resultierende Energie für eine Schusskontrolleinrichtung zum Unterbrechen der Fremdenergiezufuhr. Bei einem nicht gebrochenen Schuss und dem Ausbleiben einer Rückbewegung wird ein Ausrücken eines Steuernockens der Einrichtung aus einer zurückgezogenen Position in eine Mitnahmeposition verhindert, während ein Schalthebel durch einen Unterbrechernocken in eine Position transportiert wird, in der die kontinuierliche Drosselung der Energiezufuhr erreicht wird. Der Nachteil dieser Lösung liegt gleichfalls im hohen konstruktiven Aufwand und dem damit verbundenen Gewicht.The DE 32 18 550 C2 discloses a blocking device for a machine gun with a foreign-driven shutter drive. This is an energy resulting from the shot development for a shot control device for interrupting the external energy supply. In a non-broken shot and the absence of return movement, disengagement of a control cam of the device from a retracted position to a driving position is prevented while a shift lever is being transported by a disconnector cam to a position where the continuous restriction of the power supply is achieved. The disadvantage of this solution is also the high design complexity and the associated weight.

Die DE 36 27 362 C , welche einen Ausgangspunkt für den unabhängigen Anspruch 1 bildet, beschreibt einen Schnell-Stopp für eine Maschinenwaffe mit Fremdantrieb. Die Maschinenwaffe weist unterhalb des Verschlusses eine im Waffengehäuse eingebundene Steuerwalze auf. Mit dieser ist funktional der Schnell-Stopp verbunden, wobei wesentliche raumaufwändige Elemente des Schnell-Stopps in der Steuerwalze angeordnet sind. Zur Auslösung eines Bremsvorganges befindet sich ein Fanghebel des Schnell-Stopps oder ein Abzugshebel eines Abzuges in einer tangential eingerasteten Stellung der einzigen Fangkante einer den Zentraldorn koaxial umschließenden Bremsscheibe. Für den Anpressvorgang der Bremslamellen enthalten die Bremsscheiben und eine getriebeseitig mit der Steuerwalze verbundene Steuerscheibe an den jeweils einander zugekehrten Stirnseiten eine als axiales Verschiebemittel ausgebildete ineinander greifende Schrägverzahnung.The DE 36 27 362 C , which forms a starting point for independent claim 1, describes a quick stop for a foreign-powered machine gun. The machine gun has below the closure on a wound in the weapon housing control roller. With this functionally the quick-stop is connected, wherein substantial space-consuming elements of the quick-stop are arranged in the control roller. To trigger a braking operation is a catch lever of the quick stop or a trigger of a trigger in a tangentially engaged position of the single catching edge of the central mandrel coaxially enclosing disc. For the pressing operation of the brake discs, the brake discs and a transmission side connected to the control roller control disc at the respective mutually facing end faces formed as an axial displacement means interlocking helical teeth.

Der JP 07-174490 A ist eine Sicherheitseinrichtung entnehmbar, die am unter dem Verschluss befindlichen Steuerkörper mit Steuerkurve angebracht ist. Dabei greift ein Hebel an eine Nut des Steuerkörpers ein. Wenn der Rückstoß der Waffe erfolgt, wird der Hebel weggedrückt, sodass der Steuerkörper in der Rückstoßbewegung freigegeben wird. Bei einem Ausbleiben des Rückstoßes bleibt der Steuerkörper unterstellt.Of the JP 07-174490 A a safety device is removable, which is attached to the located under the lock control body with cam. In this case, a lever engages a groove of the control body. When the recoil of the weapon, the lever is pushed away, so that the control body is released in the recoil movement. In the absence of recoil, the control body remains subordinate.

Das sich mit einer rotationssymmetrischen Verschlusszuführung stellende Problem liegt nun darin, einen Schnellstopp einzubinden, der in kürzester Zeit funktionsfähig in das System eingreift, dieses aber nicht zerstört.The problem with a rotationally symmetrical shutter feed is now to include a quick stop, which engages in a functional manner in the shortest possible time, but this does not destroy.

Hier stellt sich die Erfindung die Aufgabe, einen Schnellstopp für eine derartige Munitions- und Verschlusszuführung aufzuzeigen.Here, the invention has the task to show a quick stop for such ammunition and shutter supply.

Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1. Vorteilhafte Ausführungen sind in den Unteransprüchen aufgezeigt.The object is achieved by the features of claim 1. Advantageous embodiments are shown in the subclaims.

Ausgehend von einem rotationssymmetrisch angebrachten Steuerkörper, über den das Öffnen und Schließen des Verschlusses realisiert wird, liegt der Erfindung die Idee zugrunde, einen Schnellstopp einzubinden, der eine am Steuerkörper eingebundene Unterstellung aufweist, die, wenn ein Schuss ausbleibt, an den Steuerkörper angreift und damit den Steuerkörper am Weiterdrehen hindert. Das dadurch auftretende Stoppen der Rotationsenergie des Steuerkörpers wird des Weiteren in eine axiale Bewegung umgewandelt, um ein Brechen des Schnellstopps bzw. des Steuerkörpers zu vermeiden. Dazu ist ein vorzugsweise am Steuerkörper eingebundener Kraftaufnehmer vorgesehen, der die restliche Rotationsenergie als axiale Bewegung aufnimmt.Starting from a rotationally symmetrically mounted control body, via which the opening and closing of the closure is realized, the invention is based on the idea to incorporate a quick stop, which has a subordinate position on the control body, which, if a shot fails, acts on the control body and thus prevents the control body from further rotation. The resulting stopping of the rotational energy of the control body is further converted into an axial movement in order to avoid a break of the quick stop or the control body. For this purpose, a preferably integrally connected to the control body force transducer is provided, which receives the remaining rotational energy as axial movement.

Es wird somit erfindungsgemäß ein Stoppmittel vorgeschlagen, das dann, wenn der Schuss ausbleibt und ein Waffenrücklauf oder dergleichen fehlt, eine Unterstellung bewirkt, wodurch ein Weiterdrehen des Steuerkörpers unterbunden wird. Um jedoch einen Bruch der Vorrichtung zu vermeiden, sieht die Erfindung in Weiterführung vor, eine Energie abbauende Einrichtung einzubinden, um so die gestoppte Rotationsenergie abzubauen bzw. aufzunehmen.It is thus proposed according to the invention, a stop means, which then, if the shot fails and a weapon return or the like is missing causes a subordination, whereby further rotation of the control body is prevented. However, in order to avoid a breakage of the device, the invention further contemplates to incorporate an energy-degrading device, so as to reduce or stop the stopped rotational energy.

Zur Lösung dieses Problems ist am Steuerkörper beispielsweise eine stirnseitig eingearbeitete Verzahnung vorgesehen, in die ein Gegenstück, ebenfalls mit einer Verzahnung, eingreift. Ein Kraftaufnehmer für die Restenergie ist seinerseits vorzugsweise im Gegenstück eingebunden und wird in einer einfachsten Form durch Federn gebildet.To solve this problem, for example, a front-side toothing is provided on the control body, in which a counterpart, also with a toothing, engages. A force transducer for the residual energy is in turn preferably integrated in the counterpart and is formed in a simplest form by springs.

Erfolgt ein Waffenrücklauf oder wird ein sich aufbauender Gasdruck für den Schnellstopp bzw. die Prüfung der exakten Funktionsweise berücksichtigt, wird das Stoppmittel weggesteuert, der Antrieb läuft normal weiter. - Ein Gasdruck wird beispielsweise bei einer schwimmenden Lagerung der Waffe (Schuss- Teilrücklauf- Schuss) bevorzugt.If a weapon return occurs or if a build-up gas pressure is taken into account for the quick stop or the check of the exact mode of operation, the stop means is controlled away, the drive continues to run normally. - A gas pressure is preferred, for example, in a floating storage of the weapon (shot partial return shot).

Bleibt der Schuss aus, bleibt die Unterstellung unterstellt. Das weitere Verdrehen des Steuerkörpers wird verhindert. Die restliche Energie des gestoppten Steuerkörpers wird durch den Kraftaufnehmer aufgenommen, wobei das Gegenstück aus der Verzahnung des Steuerkörpers herausläuft. Dazu besitzt die Verzahnung des Steuerkörpers einerseits eine entgegen der Drehrichtung des Steuerkörpers weisende bzw. verlaufende Gleitfläche und andererseits eine kantige Form. Entsprechend ist die Zahnkonfiguration am Gegenstück.If the shot remains off, the subordination remains subordinate. The further rotation of the control body is prevented. The remaining energy of the stopped control body is absorbed by the force transducer, wherein the counterpart runs out of the toothing of the control body. For this purpose, the toothing of the control body on the one hand has a counter to the direction of rotation of the control body facing or extending sliding surface and on the other hand, an edgy shape. Accordingly, the tooth configuration is at the counterpart.

In einer einfachsten Ausführung ist das Stoppmittel ein Hebel. Dieser greift in die umfangsseitig am Steuerkörper eingebundene Unterstellung, die ihrerseits vorzugsweise am Gegenstück eingebunden ist, sodass das Weggleiten des Gegenstückes vom Steuerkörper unterstütz wird.In a simplest embodiment, the stop means is a lever. This engages in the circumferentially integrated on the control body sub-position, which in turn is preferably involved in the counterpart, so that the sliding away of the counterpart is supported by the control body.

Alternativ besteht die Möglichkeit, dass das Stoppmittel erst beim Ausbleiben an die Unterstellung angreift, wenngleich dies sicherlich technisch aufwändiger ist.Alternatively, there is the possibility that the stop means will only attack if it fails to reach the position, although this is certainly technically complex.

Anhand eines Ausführungsbeispiels mit Zeichnung soll die Erfindung näher erläutert werden.Reference to an embodiment with drawing, the invention will be explained in more detail.

In Fig. 1 ist mit 1 ein Steuerkörper mit einer mantelseitigen Steuerkurve 2 sowie einer stirnseitig eingebundenen Steuerkurve 3 gekennzeichnet. Über die mantelseitige Steuerkurve 2 wird ein Verschluss und über die Stirnkurve 3 werden Verriegelungssteine 20 des Verschlusses bewegt, letztere zum Öffnen oder Verschließen eines Ladungsraumes 21 einer nicht näher dargstellten Waffe. Eine weitere, vorzugsweise an der anderen Stirnseite des Steuerkörpers 1 vorgesehene Stirnkurve 4 ist in Form einer Verzahnung 5 ausgeführt. In die Verzahnung 5 greift ein Gegenstück 6 mit einer (Gegen-)Verzahnung 7 ein. Die Form der Verzahnung 5, 7 ist vergleichbar mit einem kantigen Z und ermöglicht so, dass das Gegenstück in der freien Drehrichtung mitgenommen wird, in der Sperrrichtung, wenn der Steuerkörper 1 am Drehen gehindert wird, aus der Verzahnung 5 des Steuerkörpers 1 heraus gleiten kann.In Fig. 1 is denoted by 1 a control body with a shell-side control cam 2 and a frontally integrated cam 3. About the shell-side control cam 2 is a closure and on the front curve 3 locking blocks 20 of the closure are moved, the latter for opening or closing a cargo space 21 of a weapon unspecified dargstellten. Another, preferably provided on the other end face of the control body 1 end curve 4 is designed in the form of a toothing 5. In the toothing 5 engages a counterpart 6 with a (counter) teeth 7 a. The shape of the teeth 5, 7 is similar to an angular Z and thus allows the counterpart is taken in the free direction of rotation, in the reverse direction, when the control body 1 is prevented from rotating, from the teeth 5 of the control body 1 can slide out.

Im Gegenstück 6 gelagert ist ein Kraftaufnehmer 8, hier mehrere Federn (Fig. 2). Eine vergrößerte Darstellung ist zudem der Fig. 3 entnehmbar. Mit dem Gegenstück 6 funktional in Verbindung stehend ist einer Unterstellung 9 am Steuerkörper 1 eingebunden, an die ein Hebel 10 angreift. Mit 11 ist ein waffengehäusefestes Teil gekennzeichnet, dass beispielsweise den Hebel 10 trägt.Mounted in the counterpart 6 is a force transducer 8, here several springs ( Fig. 2 ). An enlarged view is also the Fig. 3 removable. Functionally associated with the counterpart 6, a sub-position 9 is integrated on the control body 1, to which a lever 10 engages. 11 with an armor housing fixed part is characterized, for example, the lever 10 carries.

Die Funktionsweise des Schnellstopps ist wie folgt, wobei sich auf die in der EP 1 767 891 A1 näher beschriebene Zuführung des Verschlusses über den Steuerkörper 1 Bezug genommen wird:

  • Bei erfolgtem Schuss wird der Hebel 10 von der Unterstellung 9 bevorzugt weggedreht, der Steuerkörper 1 wird durch Ablaufen eines nicht näher dargestellten Mitnehmers in der Steuerkurve 2 weiter gedreht. Ebenfalls mitgedreht wird das Gegenstück 6 mit dem Kraftaufnehmer 8. Dies erfolgt durch die kantige Form beider Verzahnungen 5 und 7.
The operation of the quick stop is as follows, referring to the in the EP 1 767 891 A1 further described supply of the closure via the control body 1 is referred to:
  • When shot, the lever 10 is preferably rotated away from the lower position 9, the control body 1 is further rotated by running a driver not shown in the control cam 2. Also rotated is the counterpart 6 with the force transducer 8. This is done by the angular shape of both teeth 5 and 7.

Bleibt jedoch der Schuss aus, greift der Hebel 10, der nach jedem erfolgtem Wegdrücken wieder in seine Ausgangslage überführt wird, weiterhin an der Unterstellung 9 an. Zeitgleich wird der nicht näher dargestellte Fremdantrieb (dieser greift in eine Verzahnung des Steuerkörpers 1) gestoppt. Der Steuerkörper 1 wird nun seinerseits nicht mehr weiter gedreht, da der (nicht näher dargstellte) Mitnehmer in der mantelseitigen Steuerkurve 2 nicht weiter bewegt wird (Verschlussbewegung wird unterbunden - Verschlussriegel bleiben verriegelt).If, however, the shot remains off, the lever 10, which is returned to its initial position after each successful pushing away, continues to engage the lower part 9. At the same time, the third-party drive not shown (this engages in a toothing of the control body 1) is stopped. The control body 1 is in turn no longer rotated, since the (unspecified dargstellte) driver in the shell-side control cam 2 is not moved (closure movement is prevented - locking latch remain locked).

Allein die Masse des Steuerkörpers 1 bewirkt jedoch, dass noch eine sogenannte Restenergie im Steuerkörper 1 vorhanden ist, die den Steuerkörper 1 weiter dreht. Diese Restenergie wird dadurch abgebaut, dass mit dem Weiterdrehen des Steuerkörpers 1 das Gegenstück 6 aus der Verzahnung 5 der Stirnkurve 4 herausgedreht und gegen den Kraftaufnehmer 8 gedrückt wird, wodurch die massenbedingte (Rest-) Bewegung und damit die restliche Rotationsenergie des Steuerkörpers 1 in eine axiale Bewegung umgewandelt und abgebaut / aufgenommen wird. Der Steuerkörper 1 kann somit nur noch soweit drehen bis die Rotationsenergie desselben gleich groß ist wie die des Kraft- bzw. Energieaufnehmers (des Federpaketes). Der Steuerkörper 1 darf im Übrigen nur soweit gedreht werden, bis die stirnseitige Verriegelungskurve die Verriegelung öffnen kann.However, the mass of the control body 1 causes only a so-called residual energy in the control body 1 is present, which rotates the control body 1 continues. This residual energy is reduced by the fact that with the further rotation of the control body 1, the counterpart 6 is rotated out of the toothing 5 of the end curve 4 and pressed against the force transducer 8, whereby the mass-related (residual) movement and thus the remaining rotational energy of the control body 1 in a axial movement is converted and degraded / recorded. The control body 1 can thus only rotate until the rotational energy of the same is the same as that of the force or energy absorber (of the spring assembly). Incidentally, the control body 1 may only be rotated until the frontal locking cam can open the lock.

Claims (6)

  1. Quick-stop mechanism for a drive by means of a control body (1) which is fitted in a rotationally symmetrical manner on the weapon casing and is intended for a linear feed of a breech of an automatic cannon, wherein the breech is opened and closed via the control body (1), having
    • a toothing formation (5), which is made on the end side of the control body and in which engages a counterpart (6) with a toothing formation (7),
    • a retainer (9), which is fitted on the counterpart (6), and incorporated on the control body (1), and is in functional connection with the counterpart (6),
    • a force transducer, which is mounted in the counterpart, wherein
    • the retainer (9), when a shot has been fired, frees the movement of the control body (1) and, when a shot has not been fired, prevents the control body (1) from moving, and
    • the counterpart
    ∘ is carried along in a free direction of rotation of the control body, and
    ∘ can slide out of the toothing formation (5) of the control body in the blocking direction of the control body, counter to a force exerted by the force transducer,
    and therefore the stopped rotational energy is dissipated and/or absorbed by the force transducer.
  2. Quick-stop mechanism according to Claim 1, characterized in that the shape of the toothing formation (5, 7) is comparable with an angular Z.
  3. Quick-stop mechanism according to Claim 2, characterized in that the force transducer (8) is in the form of springs.
  4. Quick-stop mechanism according to one of Claims 1 to 3, characterized in that a lever (10), which is carried by a weapon-casing-mounted part (11), acts on the retainer (9).
  5. Quick-stop mechanism according to Claim 4, characterized in that the lever (10), once pushed away in each case, is transferred back into its starting position, but, if a shot has not been fired, continues to act on the retainer (9).
  6. Weapon having a quick-stop mechanism according to one of Claims 1 to 5.
