Description

Die Erfindung betrifft eine Unbalance-Ausgleichsvorrich­tung für eine Waffenanlage, insbesondere bei einer schweren Waffe, mit einem in Elevationsrichtung schwenk­baren, das Waffenrohr tragenden Teil, der über einen Schildzapfen in einem festen Gestell gelagert ist, wobei der Schwerpunkt des schwenkbaren Teils außerhalb der Drehachse des Schildzapfens liegt, bei der ein dem Unbalance-Moment entgegenwirkendes Drehmoment durch mindestens eine Feder erzeugt wird.The invention relates to an unbalance compensation device for a weapon system, in particular in the case of a heavy weapon, with a part which can be pivoted in the elevation direction and which carries the weapon barrel and is mounted in a fixed frame via a shield pin, the center of gravity of the pivotable part outside the axis of rotation of the shield pin is at which a torque counteracting the imbalance torque is generated by at least one spring.

Eine derartige Unbalance-Ausgleichsvorrichtung ist in der älteren, gegenüber dem Prioritätstag der vorliegen­den Anmeldung nicht vorveröffentlichten EP 0 357 940 A1 beschrieben. Gemäß dem älteren Vorschlag sollte eine derartige Unba­lance-Ausgleichsvorrichtung so ausgestaltet werden, daß sie sehr einfach ausgebildet ist und bei geringem Eigen­gewicht und äußerst geringem Platz bedarf auch bei großen Richtwinkeln ein guter Ausgleich des Unbalance-Momentes erreicht wird.Such an imbalance compensation device is described in the older EP 0 357 940 A1, which was not prepublished compared to the priority date of the present application. According to the older proposal, such an unbalance compensation device should be designed in such a way that it is very simple and, with a low dead weight and extremely small space, good balance of the unbalance moment is achieved even with large straightening angles.

Dies wird bei dem älteren Vorschlag dadurch erreicht, daß als Feder mindestens eine Drehstabfeder dient, deren erstes Ende drehfest mit dem Gestell verbunden ist, während das zweite Ende über ein Getriebe mit dem schwenkbaren Teil der Waffe verbunden ist.This is achieved in the older proposal in that at least one torsion bar spring serves as the spring, the first end of which is connected to the frame in a rotationally fixed manner, while the second end is connected to the pivotable part of the weapon via a gear.

Die vorliegende Erfindung bezweckt eine Verbesserung und weitere Ausbildung dieses älteren Vorschlages.The present invention aims to improve and further develop this older proposal.

Der Erfindung liegen folgende Überlegungen zugrunde:The invention is based on the following considerations:

Bei einer Unbalance-Ausgleichsvorrichtung nach dem Hauptpatent wird die zum Unbalance-Ausgleich zur Verfü­gung stehende Drehstabfederenergie EFD, die durch das Getriebe auf die Waffe übertragen wird, bei linearer Kennlinie durch folgende Gleichung bestimmt:

Figure imgb0001
Mit cD = Drehsteifigkeit der Drehstabfeder
α1G = Verdrehwinkel der Drehstabfeder bei minima­ler Elevation des schwenkbaren Teils der Waffe
α1V = Verdrehwinkel der Drehstabfeder bei maxima­ler Elevation des schwenkbaren Teils der Waffe.In the case of an imbalance compensation device according to the main patent, the torsion bar spring energy E FD available for imbalance compensation, which is transmitted to the weapon by the transmission, is determined with the linear characteristic by the following equation:
Figure imgb0001
 With c D = torsional stiffness of the torsion bar spring
α 1G = torsion angle of the torsion bar with minimal elevation of the swiveling part of the weapon
α 1V = torsion angle of the torsion bar at maximum elevation of the swiveling part of the weapon.

Die zum vollständigen Unbalance-Ausgleich einer Waffe notwendige Energie Eu ist die mechanische Arbeit, die der Waffe bei der Drehung aus der kleinsten bis zur größten Elevation zugeführt werden muß. Sie ergibt sich aus folgenden Gleichungen:

Figure imgb0002
Mit Mu20 = größtes Unbalance-Moment der Waffe bei der Weffenelevation α₂ = 0°
α2max = maximale Elevation des schwenkbaren Teils der Waffe
α2min = minimale Elevation des schwenkbaren Teils der Waffe.The energy E u necessary for the complete balancing of a weapon is the mechanical work which the weapon must be supplied with when rotating from the smallest to the greatest elevation. It results from the following equations:
Figure imgb0002
 With M u20 = greatest imbalance moment of the weapon with the weapon elevation α₂ = 0 °
α 2max = maximum elevation of the swiveling part of the weapon
α 2min = minimum elevation of the swiveling part of the weapon.

Es kann sich ergeben, daß die in der aus räumlichen oder anderen Gründen ausgewählten Drehstabfeder gespeicherte Energie EFD wesentlich kleiner ist als die zum vollstän­digen Unbalance-Ausgleich notwendige Energie Eu.It may result that the energy E FD stored in the torsion bar spring selected for spatial or other reasons is significantly smaller than the energy E u necessary for complete unbalance compensation.

Der Erfindung liegt die Aufgabe zugrunde, in Weiterbil­dung des Gegenstandes des älteren Vorschlages eine einfache Möglichkeit zu schaffen, weitere Energie zu speichern, um dennoch zu einem fast vollständigen Unba­lance-Ausgleich zu gelangen.The invention is based on the object, in a further development of the subject matter of the older proposal, to provide a simple possibility for storing further energy in order nevertheless to achieve an almost complete imbalance compensation.

Die Lösung dieser Aufgabe geschieht erfindungsgemäß dadurch, daß das oben erwähnte Getriebe mindestens ein zusätzliches Federelement enthält.This object is achieved according to the invention in that the above-mentioned gear contains at least one additional spring element.

Bei einer vorteilhaften Ausführungsform der Erfindung weist das Getriebe einen drehfest mit dem oben erwähnten zweiten Ende der Drehstabfeder verbundenen Hebel auf, der gelenkig mit einem am schwenkbaren Teil der Waffe angelenkten Federbein mit mindestens einer Druckfeder verbunden ist. Dabei kann diese Druckfeder mittels eines Anschlags vorspannbar ausgebildet sein und die Auslen­kung dieser Druckfeder kann durch einen Anschlag be­grenzt sein.In an advantageous embodiment of the invention, the transmission has a lever which is connected in a rotationally fixed manner to the above-mentioned second end of the torsion bar spring and which is connected in an articulated manner to a spring strut articulated on the pivotable part of the weapon with at least one compression spring. This compression spring can be designed to be prestressable by means of a stop and the deflection of this compression spring can be limited by a stop.

Es wird darauf hingewiesen, daß eine Reihe von Merkmalen des älteren Vorschlags in Verbindungen mit den Merkmalen der vorliegenden Erfindung zu besonders vorteilhaften Ausführungsformen führt. Insbesondere ist es vorteil­haft, wenn die Drehstabfeder mindestens auf einem Teil ihrer Länge konzentrisch in einem drehbar im Gestell gelagerten Schutzrohr angeordnet ist, dessen eines Ende drehfest mit dem zweiten Ende der Drehstabfeder verbun­den ist und daß das die Drehbewegung übertragende Ge­triebe mit dem Schutzrohr verbunden ist. Das Schutzrohr kann dabei selbst als Drehstabfeder ausgebildet sein.It is pointed out that a number of features of the older proposal in connection with the features of the present invention lead to particularly advantageous embodiments. In particular, it is advantageous if the torsion bar spring is arranged concentrically at least over part of its length in a protective tube rotatably mounted in the frame, one end of which is connected in a rotationally fixed manner to the second end of the torsion bar spring and that the transmission transmitting the rotary movement is connected to the protective tube. The protective tube can itself be designed as a torsion bar spring.

Der Grundgedanke der Erfindung besteht darin, weitere Übertragungsglieder im Getriebe zwischen Drehstabfeder und Waffe als Federelemente zu gestalten, welche die zum vollständigen Unbalance-Ausgleich fehlende Energie speichern. Als besonders vorteilhaft eignet sich z.B. in einem Viergelenkgetriebe die Ausbildung der Verbindung zwischen dem mit dem zweiten Ende der Drehstabfeder verbundenen Nebel und dem schwenkbaren Teil der Waffe als weiterer Energiespeicher in Form eines Federbeins, wobei die Druckfeder z.B. bei linearer Federkennlinie unter Berücksichtigung des variablen Getriebeüber­setzungsverhältnisses zur Anpassung an das Unbalance-­Moment so ausgelegt werden muß, daß die folgenden Ener­giegleichungen angenähert erfüllt werden.

im folgenden wird anhand der beigefügten Zeichnungen ein Ausführungsbeispiel für eine Unbalance-Ausgleichsvor­richtung nach der Erfindung näher erläutert.The basic idea of the invention is to design further transmission elements in the transmission between the torsion bar spring and the weapon as spring elements, which store the energy which is missing for complete unbalance compensation. Particularly advantageous, for example, in a four-bar transmission is the formation of the connection between the mist connected to the second end of the torsion bar spring and the pivotable part of the weapon as a further energy store in the form of a spring strut, the compression spring, for example in the case of a linear spring characteristic, taking into account the variable transmission ratio to adapt to the imbalance torque, must be designed such that the following energy equations are approximately fulfilled.

An exemplary embodiment of an imbalance compensation device according to the invention is explained in more detail below with reference to the accompanying drawings.

In den Zeichnungen zeigen:

  • Fig. 1 in schematischer, teilweise geschnittener Dar­stellung einen Teil einer Waffenanlage am Turm eines Kampfpanzers mit einer Unbalance-­Ausgleichseinrichtung von oben;
  • Fig. 2 die Waffenanlage mit Unbalance-Ausgleichsvor­richtung nach Fig. 1 in einer teilweise ge­schnittenen Seitenansicht;
  • Fig. 3 in einer graphischen Darstellung die Unbalance-­Kurve der Waffenanlage zusammen mit der Kenn­linie der Ausgleichsvorrichtung.
The drawings show:
  • Figure 1 is a schematic, partially sectioned view of part of an armament system on the turret of a main battle tank with an imbalance compensation device from above.
  • FIG. 2 shows the weapon system with an unbalance compensation device according to FIG. 1 in a partially sectioned side view;
  • Fig. 3 is a graphical representation of the imbalance curve of the weapon system together with the characteristic of the balancing device.

In Fig. 1 und 2 ist in stark schematisierter Darstellung die Waffenanlage im Turm eines Kampfpanzers zu sehen, wobei von der Waffenanlage der das feste Gestell, also die Lafette bildenden Turm 2, sowie der aus Waffenrohr und Wiegenkörper bestehende schwenkbare Teil 1 darge­stellt sind. Der schwenkbare Teil 1 ist über einen Schildzapfen 1.1 im festen Gestell 2 in Elevationsrich­tung schwenkbar gelagert und kann durch einen Richtan­trieb 3 verschwenkt werden.1 and 2, the weapon system in the turret of a main battle tank can be seen in a highly schematic representation, the weapon system depicting the tower 2 which forms the fixed frame, that is to say the mount, and the pivotable part 1 which consists of the weapon barrel and the cradle body. The pivotable part 1 is pivotally mounted in the fixed frame 2 in the elevation direction via a shield pin 1.1 and can be pivoted by a directional drive 3.

Innerhalb des Innenraums 2.1 des Turms 2 ist parallel zur Drehachse des Schildzapfens 1.1, also quer zur Elevationsrichtung, in Schußrichtung vor dem Schild­zapfen 1.1 und unterhalb des schwenkbaren Teils 1 der Waffe eine Drehstabfeder 4 angeordnet, deren eines Ende 4.0 über eine Kerbverzahnung 4.6 drehfest in einem mit dem Turm 2 verbundenen Lagerbock 2.2 fixiert ist, während das freie Ende 4.1 der Drehstabfeder 4 ebenfalls über eine Kerbverzahnung 4.6 drehfest mit einem Schutz­rohr 4.3 verbunden ist, das die Drehstabfeder 4 auf etwa der Hälfte ihrer Länge konzentrisch umgibt und das über Kugel- und Rollenlager 4.4 in den Seitenwänden 2.3 des Waffenschachtes drehbar gelagert ist. Am äußeren Umfang des Schutzrohres 4.3 ist ein Nebel 4.2 befestigt, der gelenkig mit einem Ende eines Federbeins 5 verbunden ist, dessen anderes Ende am schwenkbaren Teil 1 der Waffe angelenkt ist. Das Federbein 5 enthält eine Druck­feder 5.1, deren Vorspannung durch einen verschraubbaren Anschlag 5.2 verändert werden kann. Weiterhin begrenzt ein fester Anschlag 5.3 die Auslenkung der Druckfeder 5.1.Within the interior 2.1 of the turret 2, a torsion bar spring 4 is arranged parallel to the axis of rotation of the shield pin 1.1, that is to say transversely to the direction of elevation, in the weft direction in front of the shield pin 1.1 and below the pivotable part 1 of the weapon, one end of which 4.0 is non-rotatably in one via a serration 4.6 with the tower 2 connected bearing block 2.2 is fixed, while the free end 4.1 of the torsion bar 4 is also non-rotatably connected via a serration 4.6 with a protective tube 4.3, which surrounds the torsion bar 4 concentrically for about half its length and that via ball and roller bearings 4.4 is rotatably mounted in the side walls 2.3 of the weapon shaft. On the outer circumference of the protective tube 4.3, a mist 4.2 is fastened, which is connected in an articulated manner to one end of a spring strut 5, the other end of which is articulated on the pivotable part 1 of the weapon. The strut 5 contains a compression spring 5.1, the pretension of which can be changed by a screwable stop 5.2. Furthermore, a fixed stop 5.3 limits the deflection of the compression spring 5.1.

Das Drehmoment der Drehstabfeder 4 wird zunächst auf das infolge seiner elastischen Eigenschaften ebenfalls als Drehstabfeder wirkende Schutzrohr 4.3 übertragen, von dem es über den Hebel 4.2 und das Federbein 5 schließ­lich auf den schwenkbaren Teil 1 der Waffe übertragen wird. Durch entsprechende Wahl des Anlenkungspunktes des Federbeins 5 am schwenkbaren Teil 1 der Waffe ist ein Kurbelradius 1.2 vorgegeben, während der Kurbelradius des Hebels 4.2 mit 4.5 bezeichnet ist. Durch ent­sprechend unterschiedliche Wahl dieser beiden Kurbelra­dien 1.2 bzw. 4.5 kann die Vorspannung, der geeignete Verdrehwinkel und das zu übertragende Moment der Dreh­stabfeder 4 variiert werden. Die Auslegung des als weitere Energiespeicher dienenden Federbeins 5 geschieht nach den oben angegebenen Formeln.The torque of the torsion bar 4 is first transmitted to the protective tube 4.3, which also acts as a torsion bar due to its elastic properties, from which it is finally transmitted to the pivotable part 1 of the weapon via the lever 4.2 and the spring strut 5. A suitable selection of the point of articulation of the spring strut 5 on the pivotable part 1 of the weapon predefines a crank radius 1.2, while the crank radius of the lever 4.2 is denoted by 4.5. The preload, the suitable angle of rotation and the torque of the torsion bar spring 4 to be transmitted can be varied by appropriately different selection of these two crank radii 1.2 and 4.5. The spring strut 5 serving as a further energy store is designed according to the formulas given above.

In Fig. 2 sind zwei verschiedene Stellungen der Waffen­anlage 1 mit ausgezogenen bzw. strichpunktierten Linien und die entsprechende Lage des Hebelgetriebes einge­zeichnet. In der mit ausgezogenen Linien dargestellten Stellung, die einer Stellung der Waffe 1 mit großer Elevation entspricht, besitzt das Federbein 5 ersicht­lich eine etwas größere Länge als in der mit strichpunk­tierten Linien angedeuteten Stellung, die einer Stellung der Waffe 1 bei kleiner Elevation entspricht. Durch diese Längenänderung wird das Getriebeübersetzungsver­hältnis in der gewünschten Weise angepaßt.In Fig. 2 two different positions of the weapon system 1 are drawn with solid or dash-dotted lines and the corresponding position of the lever mechanism. In the position shown with solid lines, which corresponds to a position of the weapon 1 with a high elevation, the strut 5 obviously has a somewhat longer length than in the position indicated by dash-dotted lines, which corresponds to a position of the weapon 1 with a small elevation. This change in length adjusts the gear ratio in the desired manner.

Fig. 3 beschreibt mit den Kurven I, II und III die vorteilhaften Auswirkungen der zusätzlich eingebrachten Druckfeder als weitere Energiespeicher am Beispiel eines Viergelenkgetriebes.Fig. 3 describes with curves I, II and III the advantageous effects of the additional pressure spring introduced as a further energy storage using the example of a four-bar transmission.

Die Kurve I zeigt das auszugleichende Waffenunbalancemo­ment in Abhängigkeit von der Waffenelevation α₂ als Kosinusfunktion.Curve I shows the weapon imbalance torque to be compensated as a function of the weapon elevation α₂ as a cosine function.

Kurve III stellt das allein durch die Drehstabfeder erreichbare Ausgleichsmoment dar, wodurch nur - wie der Vergleich mit Kurve I zeigt - ein teilweiser Unbalance­ausgleich erzielt wird.Curve III represents the compensation torque that can only be achieved by the torsion bar spring, whereby only - as the comparison with curve I shows - partial unbalance compensation is achieved.

Kurve II liefert das aus Drehstab- und Druckfeder resul­tierende Ausgleichsmoment, wobei die Druckfeder als weiterer Energiespeicher nach den obenstehenden Gleichungen ausgelegt ist.Curve II provides the compensation torque resulting from the torsion bar and compression spring, the compression spring being designed as a further energy store according to the equations above.

Wie der Vergleich mit Kurve I zeigt, ergibt sich - wie angestrebt - durch die zusätzlich integrierte Druckfeder ein fast vollständiger Unbalanceausgleich, wobei die noch bestehende geringe Differenz im Zusammenhang mit Spielunterdrückung erwünscht sein kann.As the comparison with curve I shows, as desired, the additionally integrated compression spring results in an almost complete unbalance compensation, whereby the small difference still remaining in connection with play suppression may be desirable.

Um die zum fast vollständigen Unbalance-Ausgleich not­wendige Energie, angepaßt an die Kosinuskurve der Waffenunbalance, speichern und wieder abgeben zu können, kann die Druckfeder nicht vorgespannt oder durch den veränderbaren Anschlag 5.2 vorgespannt sein. Ferner kann die Auslenkung der Druckfeder zusätzlich durch den Anschlag 5.3 begrenzt sein.In order to be able to store and release the energy necessary for almost complete unbalance compensation, adapted to the cosine curve of the weapon imbalance, the compression spring cannot be biased or biased by the variable stop 5.2. Furthermore, the deflection of the compression spring can also be limited by the stop 5.3.
