Description

Die Erfindung betrifft patronierte Munition nach dem Oberbegriff des Patentanspruchs 1.The invention relates to cartridge ammunition according to the preamble of claim 1.

Bei bekannter gattungsgleicher Munition (US-A-3 981 246) wird die Verbindung zwischen einer verbrennbaren Treibladungshülse und einem unterkalibrigen Geschoß einer patronierten Munition über eine Schraubverbindung hergestellt. Diese Schraubverbindung hat sich zwar als sehr haltbar erwiesen, sie ist jedoch sehr aufwendig, da sie zusätzliche Verbindungsteile und eine beträchtliche Montagezeit erfordert.In known ammunition of the same type (US Pat. No. 3,981,246), the connection between a combustible propellant charge shell and a sub-caliber projectile of cartridge ammunition is established by means of a screw connection. Although this screw connection has proven to be very durable, it is very complex because it requires additional connecting parts and a considerable assembly time.

Der Erfindung liegt daher die Aufgabe zugrunde, eine patronierte Munition anzugeben, bei der die Verbindung zwischen dem unterkalibrigen Geschoß und der verbrennbaren Treibladungshülse bei gleicher Belastungsfähigkeit erheblich einfacher und leichter herstellbar ausgebildet ist. Diese Aufgabe wird durch die im Patentanspruch 1 angegebene Erfindung gelöst.The invention is therefore based on the object of specifying a cartridge ammunition in which the connection between the sub-caliber projectile and the combustible propellant charge sleeve is designed to be considerably simpler and easier to manufacture with the same load capacity. This object is achieved by the invention specified in claim 1.

Vorteilhafte Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor.Advantageous embodiments of the invention emerge from the subclaims.

Gegenüber der bekannten Lösung zeichnet sich die Erfindung insbesondere dadurch aus, daß eine sichere Verbindung zwischen dem unterkalibrigen Geschoß und der aus verbrennbarem Material bestehenden Treibladungshülse durch einfaches Aufstecken zustande kommt. Dadurch wird die Montage wesentlich vereinfacht und durch Einsparung der Schrauben wird die Herstellung der patronierten Munition erheblich verbilligt. Schließlich kann im Gegensatz zu der bekannten Lösung, bei der die Treibladungshülse zur Durchführung der Verschraubung zweiteilig ausgebildet werden mußte, einstückig ausgebildet werden. Dadurch wird ein weiterer Arbeitsgang eingespart der zuvor zur Komplettierung der Treibladungshülse notwendig war.Compared to the known solution, the invention is characterized in particular by the fact that a secure connection between the sub-caliber projectile and the propellant charge sleeve made of combustible material is achieved by simply plugging it on. This considerably simplifies assembly and the saving of the screws considerably reduces the cost of producing the cartridge ammunition. Finally, in contrast to the known solution, in which the propellant charge sleeve had to be formed in two parts to carry out the screw connection, it can be formed in one piece. This saves another operation that was previously necessary to complete the propellant charge sleeve.

Die Erfindung wird nachfolgend unter Bezug auf die Zeichnung näher erläutert. Dabei zeigt

  • Fig. 1 einen Längsschnitt durch einen Teil einer patronierten Munition mit einem unterkalibrigen Geschoß, einem Treibkäfig und einer Treibladungshülse;
  • Fig. einen Längsschnitt durch ein Teilstück eines unterkalibrigen Geschosses der patronierten Munition;

  • Fig. 4 eine Aufsicht auf den Kartuschdeckel einer verbrennbaren Treibladungshülse.
The invention is explained in more detail below with reference to the drawing. It shows
  • 1 shows a longitudinal section through part of a cartridge ammunition with a sub-caliber projectile, a sabot and a propellant charge sleeve.
  • A longitudinal section through a section of a sub-caliber bullet of the cartridge ammunition;
  • 3 shows a longitudinal section through the cartridge cover of a combustible propellant charge sleeve;
  • Fig. 4 is a plan view of the cartridge cover of a combustible propellant charge sleeve.

Fig. 1 zeigt im Längsschnitt Darstellung ein Teilstück einer patronierten Munition 10, welche aus einem unterkalibrigen Geschoß 11, einem das Geschoß konzentrisch umgebenden Treibkäfig 12 und einer verbrennbaren Treibladungshülse besteht, von der in Fig. 1 ein Teilstück nämlich der mit 23 bezeichnete Kartuschdeckel dargestellt ist. Erfindungsgemäß ist die Treibladungshülse im Bereich des Kartuschdeckels 23 mit dem Geschoß 11 über eine Rastverbindung verbunden. Diese Rastverbindung stellt im Vergleich zu bekannten Geschossen diesen Typs, bei der eine Verbindung zwischen der verbrennbaren Hülse und dem Geschoß mittels Schrauben erfolgte, eine erhebliche Vereinfachung der Montage, verbunden mit einer Verringerung der Herstellungskosten dar, denn um eine sichere, allen Beanspruchungen genügende Verbindung zwischen dem Geschoß 11 und der verbrennbaren Treibladungshülse herzustellen, ist es lediglich erforderlich, die Treibladungshülse von der Heckseite auf das Geschoß her aufzuschieben bis die Rastverbindung einrastet. Weitere Montagevorgänge sind dann nicht mehr notwendig. Die Rastverbindung wird gebildet von federnd nach innen vorspringenden Teilen 18 des wulstartig umgebogenen Kartuschdeckels 23, die sich an formangepaßte Flächen 20, 21, 24 im Heckteil des Treibkäfigs anlegen.Fig. 1 shows a longitudinal section of a portion of a cartridge ammunition 10, which consists of a sub-caliber projectile 11, a sabot 12 concentrically surrounding the projectile and a combustible propellant charge sleeve, of which a section is shown in Fig. 1, namely the cartridge cover designated 23 . According to the invention, the propellant charge sleeve is connected to the projectile 11 in the region of the cartridge cover 23 via a snap-in connection. Compared to known bullets of this type, in which a connection between the combustible sleeve and the bullet was made by means of screws, this snap-in connection represents a considerable simplification of the assembly, combined with a reduction in the production costs, because a connection between all the stresses and strains is sufficient To manufacture the projectile 11 and the combustible propellant charge sleeve, it is only necessary to push the propellant charge case onto the projectile from the rear side until the snap connection engages. Further assembly processes are then no longer necessary. The latching connection is formed by resiliently inwardly projecting parts 18 of the bead-like bent cartridge cover 23, which rest on shape-matching surfaces 20, 21, 24 in the rear part of the sabot.

Diese formangepaßten Flächen sind in Fig. 2 dargestellt. Sie bestehen zunächst aus der Oberfläche 24 einer ringgrabenförmigen Vertiefung 26, welche im Heckteil des Treibkäfigs 12 eingelassen ist, weiter aus einer kegelstumpfförmigen Fläche 20, welche sich in radialer Richtung nach innen an die Oberfläche 24 anschließt, und schließlich aus der Oberfläche 21 einer Stufe 15 im heckförmigen Teil des Treibkäfigs 12. Ebenso wie in radialer Richtung nach innen, geht die Oberfläche 24 auch in radialer Richtung nach außen in eine kegelförmige Oberfläche 25 über.These form-fitting surfaces are shown in Fig. 2. They initially consist of the surface 24 of an annular trench-shaped depression 26 which is embedded in the rear part of the sabot 12, further of a truncated cone-shaped surface 20 which adjoins the surface 24 in the radial direction inwards, and finally of the surface 21 of a step 15 in the rear-shaped part of the sabot 12. Just as in the radial direction inwards, the surface 24 also merges in the radial direction outwards into a conical surface 25.

An die vorerwähnten Flächenteile legen sich die entsprechend angepaßten Oberflächen des Kartuschdeckels 23 beim Verbindungsvorgang an, und zwar in der Weise, daß die Wulst 19 des Kartuschdeckels 23 an der Oberfläche der ringgrabenförmigen Vertiefung 26 und zum Teil auch noch an der Oberfläche 25 abgestützt wird, während der Teil 18 des Kartuschdeckels 23 ganzflächig an der kegelförmig ausgebildeten Oberfläche 20 anliegt und nach dem Einrastvorgang zusätzlich noch mit seinem Endstück auf der Oberfläche 21 der Stufe 15 aufsitzt. Der Heckteil des Treibkäfigs 12, der in bekannter Weise ein Führungsband 13 trägt, ist nach hinten ganzflächig mit einer Dichtung 14 abgedeckt. Diese Dichtung besteht zweckmäßig aus Silikonkautschuk, der auf das Treibkäfigheck aufvulkanisiert ist. Die vorerwähnten Paßflächen, an die sich die Teile des Kartuschdeckels anlegen, sind erfindungsgemäß in dieser Dichtung 14 angeordnet. Beim Einführen des Geschosses in die Treibladungshülse gibt das Material der Dichtung nach und ermöglicht so ein formschlüssiges Anlegen der Teile des Kartuschdeckels 23 an die Dichtung 14. Die Oberfläche 24 der ringgrabenförmigen Vertiefung 26 geht sowohl in radialer Richtung nach innen als auch nach außen in kegelförmig ausgebildete Flächen 24 und 20 über. Die Fläche 20 bildet mit der Geschoßlängsachse 27 einen spitzen Öffnungswinkel -t, der vorzugsweise einen Wert von 20° nicht überschreitet. Andererseits schließt die Fläche 25 mit einer auf der Geschoß längsachse 27 senkrecht stehenden Fläche einen Winkel ein, dessen Wert vorzugsweise zwischen 40° und 50° liegen sollte. Das heckseitige Endstück 22 der Dichtung 14, welches die Stufe 15 trägt, ist weiterhin von einer Kugeloberfläche 28 berandet. Durch diese Maßnahmen läßt sich das Geschoß besonders leicht in die zu befestigende Treibladungshülse einführen, andererseits ergibt sich nach Einrasten der Rastverbindung eine formschlüssige und dauerhafte Verbindung zwischen dem Geschoß und der Treibladungshülse im Bereich des Kartuschdeckels 23.The correspondingly adapted surfaces of the cartridge cover 23 bear against the aforementioned surface parts during the connection process, in such a way that the bead 19 of the cartridge cover 23 is supported on the surface of the annular trench-shaped depression 26 and in part also on the surface 25, while the part 18 of the cartridge cover 23 rests over the entire surface of the conical surface 20 and, after the snap-in process, also sits with its end piece on the surface 21 of step 15. The rear part of the sabot 12, which carries a guide belt 13 in a known manner, is covered over the entire area with a seal 14 towards the rear. This seal is suitably made of silicone rubber, which is vulcanized onto the sabot rear. The aforementioned mating surfaces, against which the parts of the cartridge cover rest, are arranged according to the invention in this seal 14. When the projectile is inserted into the propellant charge sleeve, the material of the seal yields and thus enables the parts of the cartridge cover 23 to be positively attached to the seal 14. The surface 24 of the annular trench-shaped recess 26 extends conically in the radial direction as well as outwards Areas 24 and 20 over. The surface 20 forms an acute opening angle -t with the longitudinal axis 27 of the floor, which preferably does not exceed a value of 20 °. On the other hand, the surface 25 encloses an angle with a surface perpendicular to the longitudinal axis 27 of the projectile, the value of which should preferably be between 40 ° and 50 °. The rear end Piece 22 of the seal 14, which carries the step 15, is also bordered by a spherical surface 28. These measures allow the projectile to be inserted particularly easily into the propellant charge sleeve to be fastened; on the other hand, after the snap-in connection has been latched in, there is a positive and permanent connection between the projectile and the propellant charge sleeve in the region of the cartridge cover 23.

In Fig. 3 ist der Kartuschdeckel 23 in einem Längsschnitt dargestellt, während Fig.4 den Kartuschdeckel 23 in Aufsicht zeigt. Um ein federndes Anliegen des Kartuschdeckelteils 18 an der Anlagefläche 20 der Dichtung 14 zu ermöglichen und damit einen guten Formschluß zwischen diesen Flächen zu gewährleisten, wird der radial nach innen vorspringende Teil 18 des Kartuschdeckels 23, der durch wulstartiges Umbiegen des Kartuschdeckelmaterials entstanden ist, zweckmäßig geschlitzt, und zwar in der Weise, daß Schlitze 30 gleichmäßig auf dem Umfang des Teils 18 verteilt angeordnet sind. Es hat sich als besonders zweckmäßig erwiesen, wie in dem Ausführungsbeispiel in Fig. 4 dargestellt, vier Schlitze 30 vorzusehen, die jeweils 90° voneinander Abstand haben. Ausgehend von dem Endstück des Teils 18 sind die Schlitze 30 so in das Teil 18 eingebracht, daß sie höchstens bis zur Hälfte des Teils 18 reichen. Auf diese Weise wird sichergestellt, daß das Teil 18 über genügend gute Federeigenschaften und andererseits über eine ausreichende Festigkeit verfügt.3 shows the cartridge cover 23 in a longitudinal section, while FIG. 4 shows the cartridge cover 23 in a top view. In order to allow a resilient abutment of the cartridge cover part 18 against the contact surface 20 of the seal 14 and thus to ensure a good positive fit between these surfaces, the radially inwardly projecting part 18 of the cartridge cover 23, which is caused by the bulb-like bending of the cartridge cover material, is appropriately slotted , in such a way that slots 30 are arranged evenly distributed over the circumference of the part 18. It has proven to be particularly expedient, as shown in the exemplary embodiment in FIG. 4, to provide four slots 30, which are each 90 ° apart. Starting from the end piece of part 18, the slots 30 are introduced into the part 18 in such a way that they reach at most up to half of the part 18. In this way it is ensured that the part 18 has sufficiently good spring properties and, on the other hand, sufficient strength.

Bereits durch die erfindungsgemäße Rastverbindung allein läßt sich eine dauerhafte Verbindung zwischen Treibladungshülse und dem Geschoß herstellen, welche allen Anforderungen gerecht wird. Um mit Sicherheit auszuschließen, daß insbesondere bei sehr langer Lagerungsdauer oder bei Lagerung unter widrigen Umgebungsbedingungen Umwelteinflüsse sich nachteilig auf die Treibladung auswirken können, kann die Rastverbindung zusätzlich noch mit einem Klebemittel verstärkt werden. Dazu werden vor dem Aufschieben der Treibladungshülse auf das Heckteil des Geschosses die zur Verbindung bestimmten Flächen der Dichtung 14 oder des Teils 18 der Treibladungshülse 23 mit einem geeigneten Klebemittel beschichtet, welches nach Herstellung der Rastverbindung aushärtet.The snap connection according to the invention alone can produce a permanent connection between the propellant charge sleeve and the projectile, which meets all requirements. In order to rule out with certainty that environmental influences can have a disadvantageous effect on the propellant charge, particularly in the case of a very long storage period or storage under adverse environmental conditions, the latching connection can additionally be reinforced with an adhesive. For this purpose, before pushing the propellant charge sleeve onto the rear part of the projectile, the surfaces of the seal 14 or the part 18 of the propellant charge sleeve 23 intended for connection are coated with a suitable adhesive which hardens after the snap connection has been made.

Neben den bereits erwähnten Vorteilen wird durch den Wegfall von Schrauben, die bei herkömmlichen Verbindungen zwischen Treibladungshülse und Geschoß notwendig waren, bei der erfindungsgemäßen Lösung in vorteilhafter Weise das Ballastgewicht vermindert. Die Vergrößerung des Verhältnisses von Nutz zu Ballastgewicht wirkt sich besonders vorteilhaft bei KE-Munition aus.

 In addition to the advantages already mentioned, the ballast weight is advantageously reduced in the solution according to the invention by eliminating screws which were necessary in conventional connections between the propellant charge sleeve and the projectile. The increase in the ratio of useful to ballast weight has a particularly advantageous effect on KE ammunition.
