Abstract

Wedge breech block for a weapon comprises a breech wedge actuated by an opening shaft connected on its side facing a barrel mount to at least one control lever on which a pin-like carrier is fixed. At least one guide device (12) for guiding the pin-like carrier is provided on the barrel mount on the side facing the barrel. The guide device has a curved track rising from an inlet region (14) up to a highest point (26) for guiding the carrier on forward movement of the barrel so that on movement of the barrel the control lever pivots and the opening shaft is rotated to open the breech wedge. The guide device also has a linear guide track (27) which is lower than the highest point of the curved path for guiding the carrier on rearward movement of the barrel. The guide track changes into the rising curved path in the inlet region. At least the region of the curved path adjoining the inlet region is formed as points for the rearward-moving pin-like carrier.

Description

Die Erfindung betrifft einen Keilverschluß für eine Waffe mit einem gegenüber einer Rohrwiege rücklaufbaren Waffenrohr und einem Bodenstück, in dem ein quer zur Rohrseelenachse verschiebbar angeordneter, durch eine Öffnerwelle betätigbarer Verschlußkeil vorgesehen ist.The invention relates to a wedge lock for a weapon with a returnable to a pipe cradle gun barrel and a bottom piece in which a transverse to Rohrseelenachse slidably disposed, operable by a Öffnerwelle closure wedge is provided.

Bei großkalibrigen Waffen mit Querkeilverschlüssen ist es bekannt, den jeweiligen Verschlußkeil mittels einer senkrecht zur Rohrseelenachse vorgesehenen und mit einem wiegenfesten Fremdantrieb verbundenen Öffnerwelle beim Vorlauf des Waffenrohres automatisch zu öffnen, um beispielsweise nach einem Schuß die Patronenhülse zu entladen und eine neue Patrone in den Ladungsraum der Waffe einzuschieben. Nachteilig ist bei derartigen Querkeilverschlüssen unter anderem, daß ein Fremdantrieb und ein relativ aufwendiges Öffnergetriebe benötigt wird.In large-caliber weapons with cross wedge closures, it is known to automatically open the respective closure wedge by means of a normal to Rohrseelenachse and connected to a cradle-fixed external drive opener during the forward of the gun barrel, for example, after a shot to unload the cartridge case and a new cartridge in the cargo space To insert a weapon. A disadvantage of such transverse wedge closures, inter alia, that an external drive and a relatively expensive Öffnergetriebe is needed.

Aus der DE-PS 1 578 049 ist bereits ein als Bodenverschluß ausgebildeter Querverschluß bekannt, bei dem der Verschluß automatisch mit Hilfe von zwei rollenförmigen Mitnehmern geöffnet wird, die beim Vorlauf des Waffenrohres jeweils auf einer Kurvenbahn (Auflaufkurve) einer wiegenfesten Führungseinrichtung nach oben rollen und dabei den Bodenverschluß anheben. Nach dem Laden fällt der entriegelte Verschluß nach unten und verschließt das Waffenrohr. Bei dem Rücklauf des Waffenrohres wird dieses geradlinig in einer Führungsnut geführt, welche in die Kurvenbahn derart übergeht, daß die ansteigende Kurvenbahn im Bereich der Führungsnuten als nach oben ausschwenkbare Weiche ausgebildet ist. Ein separater Antrieb ist bei Waffen mit einem derartigen Bodenverschluß nicht erforderlich.From the DE-PS 1 578 049 is already trained as a bottom closure transverse closure, in which the shutter is opened automatically with the help of two roller-shaped drivers, each roll on a curved path (casserole) of a weighing guide means up during the flow of the gun barrel and thereby raise the bottom closure. After loading the unlocked lock falls down and closes the gun barrel. In the return of the gun barrel this is performed in a straight line in a guide groove, which merges into the curved path such that the rising cam track is formed in the region of the guide as swinging upwards switch. A separate drive is not required for weapons with such a bottom closure.

US-A-3866513 offenbart einen Keilverschluß für eine Waffe. US-A-3866513 discloses a wedge lock for a weapon.

Der Erfindung liegt die Aufgabe zugrunde, einen einfach aufgebauten Keilverschluß anzugeben, mit dem ein automatisches Öffnen des Verschlusses bei hoher Schußfolge möglich ist, ohne daß ein zusätzlicher Fremdantrieb erforderlich ist.The invention has for its object to provide a simply constructed wedge closure, with which an automatic opening of the closure at high firing order is possible without an additional external drive is required.

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, ähnlich wie bei Waffen mit Bodenverschluß eine Kurvenbahn an einer wiegenfesten Führungseinrichtung zur Führung eines bolzenförmigen Mitnehmers vorzusehen, wobei allerdings der Mitnehmer nicht direkt ein Heben und Senken des Verschlußkeiles verursacht, sondern eine Drehung der Öffnerwelle bewirkt, welche dann ihrerseits auf den Verschlußkeil, z.B. über ein Zahnradoder Hebelgetriebe, einwirkt.The invention is based essentially on the idea, similar to weapons with bottom closure to provide a curved path on a weighing guide means for guiding a bolt-shaped driver, although the driver does not directly cause lifting and lowering of the closure wedge, but causes a rotation of the opener, which then in turn on the closure wedge, eg via a gear or lever gear, acts.

Ähnlich wie bei den bekannten Bodenverschlüssen weist die Führungseinrichtung zur Führung des Mitnehmers beim Rücklauf des Waffenrohres eine gegenüber dem höchsten Punkt der Kurvenbahn tieferliegende gerade Führungsbahn auf, welche in den Einlaufbereich der ansteigenden Kurvenbahn übergeht, wobei mindestens der sich an den Einlaufbereich anschließende Bereich der ansteigenden Kurvenbahn der Führungseinrichtung als Weiche für den rücklaufenden zapfenförmigen Mitnehmer ausgebildet ist.Similar to the known bottom fasteners, the guide means for guiding the driver in the return of the gun barrel on the opposite side of the highest point of the cam track deeper straight track, which merges into the inlet region of the rising cam track, wherein at least the adjoining the inlet region area of the rising cam track the guide device is designed as a switch for the returning peg-shaped driver.

Als besonders vorteilhaft hat es sich erwiesen, wenn die Kurvenbahn aus mindestens zwei sich aneinander anschließenden Abschnitten besteht, wobei der erste Abschnitt der Kurvenbahn an einem ersten, sich direkt an den Einlaufbereich anschließenden Teil der Führungseinrichtung angeordnet ist und gegen den Druck einer Feder um eine senkrecht zur Längsachse des zapfenförmigen Mitnehmers angeordnete Achse schwenkbar ausgebildet ist, derart, daß beim Rücklauf des Waffenrohres der zapfenförmige Mitnehmer das erste Teil vom Waffenrohr seitlich wegschwenkt und dadurch in den Einlaufbereich gelangt.It has proved to be particularly advantageous if the curved path consists of at least two adjoining sections, the first section of the curved path being arranged on a first part of the guide device directly adjoining the inlet region and against the pressure of a spring about one vertically to the longitudinal axis of the pin-shaped carrier arranged axis is pivotally formed, such that the return of the gun barrel of the peg-shaped driver laterally pivots the first part of the barrel and thereby passes into the inlet region.

Eine derartige Führungseinrichtung weist unter anderem die Vorteile auf, daß beim Rücklauf des Waffenrohres durch den zapfenförmigen Mitnehmer nur der erste Abschnitt gedreht wird, dessen Masse gering ist, so daß sie für eine schnelle Schußfolge auf Werte > 15 m/s beschleunigt werden kann.Such a guide device has, inter alia, the advantages that only rotated the first section during the return of the gun barrel by the peg-shaped driver whose mass is low, so that it can be accelerated to a value of> 15 m / s for a fast shooting sequence.

Außerdem wird durch den abschnittsförmigen Aufbau der Kurvenbahn erreicht, daß bei einem Verschleiß der vorzugsweise aus einem gehärteten Material bestehenden Kurvenbahn nicht die gesamte Führungseinrichtung ersetzt werden muß, sondern jeweils nur das Teil, welches besonders beansprucht wurde.In addition, it is achieved by the sectional structure of the cam track that at a wear of the existing preferably made of a cured material cam track not the entire guide device must be replaced, but in each case only the part which has been particularly stressed.

Überdies hat es sich als vorteilhaft erwiesen, wenn die Kurvenbahn einen etwa sinusförmigen Verlauf aufweist. Dadurch wird eine ruck- und stoßfreie Gleitbewegung des zapfenförmigen Mitnehmers beim Öffnungshub sichergestellt.Moreover, it has proven to be advantageous if the curved path has an approximately sinusoidal course. As a result, a jerk and shock-free sliding movement of the peg-shaped driver is ensured during the opening stroke.

Bei einer weiteren Ausführungsform der Erfindung stützt sich der zapfenförmige Mitnehmer nicht nur auf der Kurvenbahn ab, sondern wird auch durch eine oberhalb der Kurvenbahn angeordnete feste Kurve geführt, so daß der Mitnehmer entlang einer ansteigenden nutenförmigen Ausnehmung geführt wird. Die obere Kurve verhindert dabei, daß bei hohen Vorlaufgeschwindigkeiten des Waffenrohres (von z.B. 2,5 m/s) der Verschluß nicht nach außen weggeschleudert wird.In a further embodiment of the invention, the peg-shaped driver is supported not only on the curved path, but is also guided by a fixed curve arranged above the curved path, so that the driver is guided along a rising groove-shaped recess. The upper curve prevents the closure from being thrown to the outside at high forward velocities of the weapon barrel (e.g., 2.5 m / s).

Als zweckmäßig hat es sich erwiesen, wenn die Länge des ersten Abschnittes der Kurvenbahn mindestens 60 % der Länge der gesamten Kurvenbahn beträgt.It has proven to be advantageous if the length of the first portion of the curved path is at least 60% of the length of the entire curved path.

Um die Führungseinrichtung oder Teile dieser Einrichtung im Bedarfsfalle schnell auswechseln zu können, ist bei einer Ausführungsform der Erfindung eine Grundplatte vorgesehen, an der das den zweiten Abschnitt der Kurvenbahn tragende zweite Teil fest und das den ersten Abschnitt der Kurvenbahn tragende erste Teil schwenkbar befestigt ist.In order to quickly replace the guide device or parts of this device in case of need, in one embodiment of the invention, a base plate is provided on which the second portion of the cam track bearing second part fixed and the first portion of the cam track bearing first part is pivotally mounted.

Ferner hat sich gezeigt, daß bei Verwendung des erfindungsgemäßen Keilverschlusses die dynamischen Belastungen wesentlich geringer sind als bei vergleichbaren Keilverschlüssen mit Öffnergetriebe zum automatischen Öffnen des Verschlußkeiles. Dadurch ist es möglich, die Grundplatte sowie das erste und zweite Teil der Führungseinrichtung aus Gußeisen herzustellen, was eine sehr kostengünstige Herstellung dieser Teile ermöglicht.Furthermore, it has been shown that when using the wedge closure according to the invention, the dynamic loads are much lower than in comparable wedge closures with Öffnergetriebe for automatically opening the closure wedge. This makes it possible to manufacture the base plate and the first and second part of the guide device made of cast iron, which allows a very cost-effective production of these parts.

In Fig. 1 ist mit 1 eine Waffe mit einem gegenüber einer Rohrwiege 2 rücklaufbaren Waffenrohr 3 bezeichnet. Das Waffenrohr 3 ist heckseitig mit einem Bodenstück 4 verbunden, welches einen Querkeilverschluß 5 aufnimmt.In Fig. 1 is denoted by 1 a weapon with respect to a pipe cradle 2 retractable gun barrel 3. The gun barrel 3 is connected at the rear with a bottom piece 4, which receives a cross wedge shutter 5.

Der Querkeilverschluß 5 umfaßt einen quer zur Rohrseelenachse 6 verschiebbar angeordneten Verschlußkeil 7 sowie eine gestrichelt dargestellte Öffnerwelle 8, welche mit Öffnerhebeln 9 verbunden ist, die auf gegenüberliegenden Seiten an dem Verschlußkeil 7 angreifen. Außerdem ist die Öffnerwelle 8 auf ihrer rechten der Rohrwiege 2 zugewandten Seite mit einem Steuerhebel 10 verbunden, an dem ein zapfenförmiger Mitnehmer 11 befestigt ist. Dieser Mitnehmer 11 greift in eine an der Rohrwiege 2 befestigten Führungseinrichtung 12 ein.The cross wedge closure 5 comprises a transversely to the tube axis 6 slidably disposed closure wedge 7 and an opener shaft 8 shown in dashed lines, which is connected to Öffnerhebeln 9, which engage on opposite sides of the closure wedge 7. In addition, the opener shaft 8 is connected on its right side facing the cradle 2 with a control lever 10, on which a pin-shaped carrier 11 is attached. This driver 11 engages in a guide device 12 attached to the tube cradle 2.

Die Führungseinrichtung 12 umfaßt eine mit der Rohrwiege 2 z.B. verschraubte und aus Gußeisen bestehende Grundplatte 13 (Fig.3), an der zur Führung des Mitnehmers 11 beim Vorlauf des Waffenrohres 3 eine von einem Einlaufbereich 14 bis zu einem höchsten Punkt 26 ansteigende Kurvenbahn 15 (Fig.2) angeordnet ist, die einen etwa sinusförmigen Anstieg besitzt.The guide device 12 includes a bolted to the cradle 2, for example, and off Cast iron existing base plate 13 ( Figure 3 ), at the for guiding the carrier 11 during the advance of the gun barrel 3 from a lead-in area 14 to a highest point 26 rising cam track 15 (FIG. Fig.2 ) is arranged, which has an approximately sinusoidal rise.

In einem vorgegebenen Abstand von der Kurvenbahn 15 ist eine obere Seitenwand 16 vorgesehen, die den gleichen Verlauf aufweist wie die Kurvenbahn 15, so daß der Mitnehmer 11 in einer nutenförmigen Ausnehmung 17 geführt wird.At a predetermined distance from the cam track 15, an upper side wall 16 is provided, which has the same course as the cam track 15, so that the driver 11 is guided in a groove-shaped recess 17.

Die Kurvenbahn 15 setzt sich aus zwei aneinander anschließende Abschnitte 18, 19 zusammen, wobei der erste Abschnitt 18 der Kurvenbahn 15 durch ein erstes, sich direkt an den Einlaufbereich 14 anschließendes Teil 20 der Führungseinrichtung 12 gebildet wird. Dieses erste Teil 20 besteht ebenfalls aus Gußeisen (z.B. 14NiCr18-Stahlfeinguß) und ist um eine senkrecht zur Längsachse des zapfenförmigen Mitnehmers 11 vorgesehene Achse 22 schwenkbar an der Grundplatte 13 der Führungseinrichtung 12 angeordnet und wird in seiner in Fig.2 dargestellten Ruhelage durch einen Stößel 23 gehalten (Fig.3). Dieser Stößel 23 wird von einer Feder 24 beaufschlagt, welche sich an der Grundplatte 13 abstützt.The cam track 15 is composed of two adjoining sections 18, 19, the first section 18 of the cam track 15 being formed by a first part 20 of the guide device 12 adjoining directly to the inlet area 14. This first part 20 is also made of cast iron (eg 14NiCr18-Stahlfeinguß) and is arranged about a perpendicular to the longitudinal axis of the peg-shaped driver 11 axis 22 pivotally mounted on the base plate 13 of the guide means 12 and is in his in Fig.2 shown rest position held by a plunger 23 ( Figure 3 ). This plunger 23 is acted upon by a spring 24, which is supported on the base plate 13.

Der zweite Abschnitt 19 der Kurvenbahn 15 wird durch ein zweites, fest mit der Grundplatte 13 verbundenes und auch aus Gußeisen bestehendes Teil 25 gebildet.The second portion 19 of the cam track 15 is formed by a second, fixedly connected to the base plate 13 and also consisting of cast iron part 25.

Außerdem besitzt die Führungseinrichtung 12 zur Führung des Mitnehmers 11 beim Rücklauf des Waffenrohres 3 eine gegenüber dem höchsten Punkt 26 der Kurvenbahn 15 tieferliegende gerade Führungsbahn 27, welche in den Einlaufbereich 14 der Kurvenbahn 15 übergeht.In addition, the guide means 12 for guiding the carrier 11 during the return of the gun barrel 3 has a relation to the highest point 26 of the cam track 15 deeper straight guide track 27, which merges into the inlet region 14 of the cam track 15.

Nachfolgend wird auf die Wirkungsweise des erfindungsgemäßen Keilverschlusses 5 eingegangen. Dabei sei angenommen, daß sich in dem Waffenrohr 3 ein Geschoß und eine Treibladung (z.B. eine Kartuschenladung) befinden und der Verschlußkeil 7 geschlossen ist.Subsequently, the operation of the wedge closure 5 according to the invention will be discussed. It is assumed that a projectile and a propellant charge (for example a cartridge charge) are located in the weapon barrel 3 and the closure wedge 7 is closed.

Wird nun die Treibladung gezündet und damit der Schuß ausgelöst, so bewirkt der Abschuß des Geschosses einen Rückstoß, der das Waffenrohr 3 samt Bodenstück 4 nach hinten verschiebt (in Fig.1 durch den Pfeil 100 angedeutet). Dabei gleitet der zapfenförmige Mitnehmer 11 auf der Führungsbahn 27 ebenfalls nach hinten und schwenkt das mit dem ersten Abschnitt 18 der Kurvenbahn 15 versehene erste Teil 20 vom Waffenrohr 3 seitlich in eine entsprechende Ausnehmung der Rohrwiege 2, so daß der Mitnehmer 11 weitgehend ungehindert in den Einlaufbereich 14 der Kurvenbahn 15 gelangt.Now, if the propellant ignited and thus fired the shot, so does the firing of the projectile recoil, which moves the gun barrel 3 together with bottom piece 4 to the rear (in Fig.1 indicated by the arrow 100). In this case, the peg-shaped carrier 11 also slides on the guideway 27 to the rear and pivots the provided with the first portion 18 of the cam track 15 first part 20 from the gun barrel 3 laterally into a corresponding recess of the tube cradle 2, so that the driver 11 largely unhindered in the inlet region 14 of the cam track 15 passes.

Nachdem das Waffenrohr 3 in seine hinterste Stellung verschoben wurde, wird es ohne Unterbrechung durch einen Rohrvorholer (nicht dargestellt) wieder nach vorne geschoben. Bei diesem Vorlauf des Waffenrohres 3 und des Bodenstückes 4 durchläuft der zapfenförmige Mitnehmer 11 die ansteigende Kurvenbahn 15 (Fig.2) und bewirkt über das Verschwenken des Steuerhebels 10 und die Drehung der Öffnerwelle 8 ein Verschwenken der Öffnerhebel 9 (Fig.4 gestrichelte Darstellung) und somit ein Öffnen des Verschlußkeiles 7 (Fig.5 gestrichelte Darstellung).After the gun barrel 3 has been moved to its rearmost position, it is pushed without interruption by a pipe pickup (not shown) back to the front. In this flow of the gun barrel 3 and the bottom piece 4 of the peg-shaped driver 11 passes through the rising cam track 15 (FIG. Fig.2 ) and via the pivoting of the control lever 10 and the rotation of the opener shaft 8 causes a pivoting of the opening lever 9 (FIG. Figure 4 dashed line) and thus an opening of the closure wedge 7 ( Figure 5 dashed line).

Sobald der Mitnehmer 11 den höchsten Punkt 26 der Kurvenbahn 15 erreicht hat und somit der Verschlußkeil 7 automatisch in "geöffneter Position" arretiert wird (nicht dargestellt), erfolgt das Ansetzen des neuen Geschosses mittels eines Ladeautomaten (nicht dargestellt) sowie das Einführen einer neuen Treibladung. Mittels eines Auslösehebels (nicht dargestellt) wird der Verschlußkeil 7 geschlossen, wobei der zapfenförmige Mitnehmer 11 dem steil abfallenden Übergangsbereich 28 zwischen der Kurvenbahn 15 und der Führungsbahn 27 folgt, so daß das Waffenrohr 3 durch den nach unten fallenden Verschlußkeil 7 verschlossen wird. Anschließend kann dann der nächste Schuß ausgelöst werden.Once the driver 11 has reached the highest point 26 of the cam track 15 and thus the shutter wedge 7 is automatically locked in the "open position" (not shown), the new bullet is applied by means of a loading machine (not shown) and the introduction of a new propellant charge , By means of a release lever (not shown), the closure wedge 7 is closed, wherein the peg-shaped carrier 11 follows the steeply sloping transition region 28 between the cam track 15 and the guideway 27, so that the weapon barrel 3 is closed by the closing wedge 7 falling down. Then then the next shot can be triggered.

Wedge breech lock for a weapon (1) having a weapon barrel (3) which can recoil with respect to a barrel cradle (2) and having a base piece (4) in which a breech wedge (7) is provided which is arranged such that it can move transversely with respect to the barrel bore axis (6) and can be operated by an opener shaft (8), and at least one guide device (12) for guiding a driver (11) which is in the form of a pin is provided on the barrel cradle (2), on the side facing the weapon barrel (3), in order to guide the driver (11) during forward movement of the weapon barrel (3), the guide device (12) has a curved track (15), which rises from an inlet area (14) to a highest point (26) and, during recoil of the weapon barrel (3), has a straight guide track (27), which is located lower than the highest point (26) of the curved track (15) and merges into the inlet area (14) of the rising curved track (15), wherein at least that area of the curved track (15) of the guide device (12) which is adjacent to the inlet area (14) is in the form of a switch for a backward-moving driver (11) in the form of a pin, characterized in that the opener shaft (8) is connected on its side facing the barrel cradle (2) to at least one control lever (10) such that, during the forward movement of the weapon barrel (3), the control lever (10) is pivoted, to which control lever (10) the driver (11) which is in the form of a pin is attached, and the opener shaft (8) is rotated in order to open the breech wedge (7), in which case the driver (11) does not directly result in the breech wedge (7) being raised and lowered but causes rotation of the opener shaft (8), which then itself acts on the breech wedge (7), for example via a gear wheel or lever transmission.
  2. Wedge breech lock according to Claim 1, characterized in that the curved track (15) comprises at least two mutually adjacent sections (18, 19), wherein the first section (18) of the curved track (15) is arranged on a first part (20), which is directly adjacent to the inlet area (14), of the guide device (12) and is designed such that it can pivot against the pressure of a spring (24) about an axis (22) which is arranged at right angles to the longitudinal axis of the driver (11), which is in the form of a pin, such that, when the weapon barrel (3) recoils, the driver (11) which is in the form of a pin moves the first part (20) laterally away from the weapon barrel (3), and thus enters the inlet area (14).
  3. Wedge breech lock according to Claim 2, characterized in that the length of the first section (18) of the curved track (15) is at least 60% of the length of the entire curved track (15).
  4. Wedge breech lock according to one of Claims 1 to 3, characterized in that the curved track (15) has an approximately sinusoidally rising profile.
  5. Wedge breech lock according to one of Claims 1 to 4, characterized in that the curved track (15) is composed of a hardened material.
  6. Wedge breech lock according to one of Claims 2 to 5, characterized in that the guide device (12) has a base plate (13) to which the second part (25), which supports the second section (19) of the curved track (15), is firmly attached and the first part (25), which supports the first section (18) of the curved track (15), is attached such that it can pivot.
  7. Wedge breech lock according to one of Claims 2 to 6, characterized in that the base plate (13) as well as the first and second parts (20, 25) of the guide device (12) are composed of cast iron.
  8. Wedge breech lock according to Claim 7, characterized in that the cast iron is a 14NiCr18 fine cast steel.
  9. Wedge breech lock according to one of Claims 1 to 8, characterized in that the driver (11) which is in the form of a pin is guided during the forward movement of the weapon barrel (3) in a groove-like recess (17), with the lower side wall of the groove-like recess (17) being formed by the curved track (15).
