Description

Die Erfindung betrifft einen Geschossansetzer für Waffen mit einer über ein erstes Antriebselement bewegbaren Ansetzkette zur Beförderung eines Geschosses in dessen Ansetzstellung und einem die Ansetzkette zur Erhöhung der Ansetzgeschwindigkeit mitnehmenden Mitnehmer, der über ein zweites Antriebselement bewegbar ist. Einen weiteren Gegenstand der Erfindung bildet eine Waffe mit einem Waffenrohr und einem Geschossansetzer zur Beförderung eines Geschosses in eine Ansetzstellung innerhalb des Waffenrohres. Geschossansetzer dienen zum Laden vor allem großkalibriger Waffen mit oftmals geteilter Munition bestehend aus dem eigentlichen Geschoss sowie den im Waffenrohr hinter dem Geschoss anzuordnenden Treibladungen. Über den Geschossansetzer wird das Geschoss in eine Ansetzstellung innerhalb des Waffenrohres der Waffe befördert, wonach dann die Treibladungen in das Waffenrohr eingebracht und die Munition verschossen werden kann.The invention relates to a Geschoßansetzer for weapons with a movable via a first drive element Ansetzkette for transporting a projectile in the Ansetzstellung and the Ansetzkette to increase the Ansetzgeschwindigkeit entraining driver, which is movable via a second drive element. Another object of the invention is a weapon with a gun barrel and a bulldozer for transporting a projectile in a Ansetzstellung within the gun barrel. Bullet teasers are used primarily for loading large-caliber weapons with often divided ammunition consisting of the actual projectile and the propellant charges to be arranged in the weapon barrel behind the projectile. About the bulldozer the projectile is conveyed into a Ansetzstellung within the gun barrel of the weapon, after which then the propellant charges introduced into the gun barrel and the ammunition can be fired.

Um hohe Kadenzen, d. h. rasche Schussfolgen erreichen zu können, ist es erforderlich, dass der Geschossansetzer das Geschoss mit einer möglichst hohen Ansetzgeschwindigkeit in dessen Ansetzstellung innerhalb des Waffenrohres befördert.To high cadences, d. H. To be able to achieve rapid firing sequences, it is necessary for the bullet teaser to transport the bullet at the highest possible piecing rate into its tying position within the weapon barrel.

Aus der EP 0 627 608 B1 ist ein Geschossansetzer bekannt, bei welchem das Geschoss über eine in Richtung des Waffenrohres bewegbare Ansetzkette, die über ein Antriebselement angetrieben wird, in die Ansetzstellung innerhalb des Waffenrohres befördert wird. Da die Ansetzgeschwindigkeit der Ansetzkette aufgrund der mechanischen Randbedingungen derartiger Ketten nicht beliebig erhöht werden kann, ist bei dem Ansetzer zusätzlich ein rohrförmiger Mitnehmer vorgesehen, welcher ebenfalls in Richtung des Waffenrohres bewegt wird und die Ansetzkette mitnimmt. Die Geschwindigkeiten des über ein separates Antriebselement angetriebenen Mitnehmers sowie der ebenfalls in Richtung des Waffenrohres angetriebenen Ansetzkette addieren sich, wodurch sich höhere Ansetzgeschwindigkeiten erreichen lassen.From the EP 0 627 608 B1 a bullet stirrer is known in which the projectile is transported via a movable in the direction of the gun barrel Ansetzkette which is driven by a drive element in the Ansetzstellung within the gun barrel. Since the Ansetzgeschwindigkeit the Ansetzkette due to the mechanical boundary conditions of such chains can not be increased arbitrarily, a tubular driver is additionally provided in the piecing, which is also moved in the direction of the gun barrel and entrains the Ansetzkette. The speeds of the driven via a separate drive element driver and also driven in the direction of the gun barrel Ansetzkette add up, which can achieve higher Ansetzgeschwindigkeiten.

Der in der EP 0 627 608 B1 beschriebene Ansetzer hat sich in der Vergangenheit hinsichtlich der zu erreichenden Ansetzgeschwindigkeiten zwar durchaus bewährt, benötigt jedoch einen vergleichsweise großen, bis unter das Waffenrohr reichenden Bauraum, der insbesondere bei auf militärischen Fahrzeugen angeordneten Waffen oftmals nicht zur Verfügung steht.The Indian EP 0 627 608 B1 described piecing has been well proven in the past with respect to the Ansetzgeschwindigkeiten to be achieved, but requires a comparatively large, reaching below the gun barrel space, which is often not available in particular arranged on military vehicles weapons.

Es ist die Aufgabe der vorliegenden Erfindung, einen Geschossansetzer bzw. eine Waffe mit einem Geschossansetzer anzugeben, die bei hoher Ansetzgeschwindigkeit einen geringen Bauraum erfordern.It is the object of the present invention to provide a bulldozer or a weapon with a bulldozer, which require a small space at high Ansetzgeschwindigkeit.

Im Hinblick auf einen Geschossansetzer der eingangs genannten Art wird diese Aufgabe dadurch gelöst, dass das erste Antriebselement auf dem Mitnehmer angeordnet ist.With regard to a Geschossansetzer of the aforementioned type this object is achieved in that the first drive element is disposed on the carrier.

Die Anordnung des ersten, die Ansetzkette bewegenden Antriebselements auf dem in Richtung des Waffenrohres über das zweite Antriebselement bewegbaren Mitnehmer erlaubt eine kompakt bauende Konstruktion des Geschossansetzers. Die Geschwindigkeiten des Mitnehmers sowie der Ansetzkette addieren sich, wodurch sich eine hohe Ansetzgeschwindigkeit erreichen lässt.The arrangement of the first, the Ansetzkette moving drive element on the movable in the direction of the gun barrel on the second drive element driver allows a compact design of the bulldozer. The speeds of the driver and the Ansetzkette add up, which can achieve a high Ansetzgeschwindigkeit.

In vorteilhafter Ausführung wird vorgeschlagen, dass der Mitnehmer ein Mitnahmeelement aufweist, welches in die Ansetzkette eingreift. Der Eingriff kann insbesondere von der Seite her zwischen zwei Kettenelemente der Ansetzkette erfolgen. Die Mitnahme kann durch formschlüssigen Eingriff des Mitnahmeelements in die Ansetzkette erfolgen.In an advantageous embodiment, it is proposed that the driver has a driving element which engages in the Ansetzkette. The engagement can take place in particular from the side between two chain elements of the Ansetzkette. The entrainment can be done by positive engagement of the driving element in the Ansetzkette.

In diesem Zusammenhang ist es von Vorteil, wenn das Mitnahmeelement durch das erste Antriebselement gebildet wird. Auf diese Weise kommt dem Antriebselement eine Doppelfunktion als Mitnahmeelement zur Mitnahme der Ansetzkette wie auch als Antriebselement zum Antrieb der Ansetzkette in Richtung des Waffenrohres zu. In diesem Zusammenhang ist es von konstruktivem Vorteil, wenn das Antriebselement bzw. das Mitnahmeelement als Zahnrad ausgebildet ist.In this context, it is advantageous if the entrainment element is formed by the first drive element. In this way, the drive element is a double function as a driving element for driving the Ansetzkette as well as a drive element for driving the Ansetzkette in the direction of the gun barrel. In this context, it is of constructive advantage if the drive element or the driving element is designed as a gear.

In konstruktiver Weiterbildung wird vorgeschlagen, dass der Mitnehmer als linear beweglicher Schlitten ausgebildet ist. Auf diese Weise lässt sich der Mitnehmer in kompakter Bauweise ausbilden. Der Mitnehmer kann hinter dem Waffenrohr in Richtung der Rohrseelenachse des Waffenrohres hin- und her bewegt werden.In constructive development, it is proposed that the driver is designed as a linearly movable carriage. In this way, the driver can be formed in a compact design. The driver can be moved behind the barrel in the direction of the tube axis of the barrel barrel back and forth.

Weiterhin wird vorgeschlagen, dass der Geschossansetzer eine das Geschoss tragende Ladeschale aufweist, an welcher die Bewegungen des Mitnehmers geführt werden. Durch die Führung der Bewegungen des Mitnehmers ergibt sich eine definierte Ansetzbewegung.Furthermore, it is proposed that the bulldozer has a charging shell carrying the projectile, on which the movements of the driver are guided. By guiding the movements of the driver results in a defined Ansetzbewegung.

In diesem Zusammenhang ist es von konstruktivem Vorteil, wenn die Ladeschale eine Ausnehmung aufweist, an deren Rändern der Mitnehmer nach Art eines Rollschlittens geführt wird.In this context, it is of constructive advantage if the charging tray has a recess, at the edges of the driver is guided in the manner of a rolling carriage.

In Ausgestaltung der Erfindung wird weiter vorgeschlagen, dass die Bewegungen der Antriebselemente über ein Übertragungselement, welches insbesondere an den Mitnehmer angeordnet ist, gekoppelt sind. Durch die Bewegungskoppelung der Antriebselemente ist es möglich, beide mit nur einem gemeinsamen Antrieb zu betreiben. Beispielsweise kann das zweite Antriebselement über einen Linearantrieb bewegt werden, über welchen dann, gekoppelt über das Übertragungselement, auch der Antrieb der Ansetzkette erfolgt.In an embodiment of the invention it is further proposed that the movements of the drive elements via a transmission element, which is arranged in particular on the driver, are coupled. Due to the motion coupling of the drive elements, it is possible to operate both with only one common drive. For example, the second drive element can be moved via a linear drive, via which then, coupled via the transmission element, the drive of the Ansetzkette done.

Schließlich wird in Bezug auf den Geschossansetzer vorgeschlagen, dass das Übertragungselement derart ausgestaltet ist, dass es infolge einer Bewegung des Mitnehmers in Rotation versetzt und diese Rotation über das erste Antriebselement in eine translatorische der Ansetzkette überführt wird. Darüber hinaus wird bei einer Waffe der eingangs genannten Art zur Lösung der Aufgabe vorgeschlagen, dass diese einen Geschossansetzer der vorbeschriebenen Art aufweist.Finally, with respect to the bullet tappet, it is proposed that the transmission element is designed in such a way that it is set in rotation as a result of a movement of the tappet and that this rotation is transferred via the first drive element into a translatory tapping chain. In addition, it is proposed in a weapon of the type mentioned to solve the problem that this has a bulldozer of the type described above.

Durch die Verwendung eines solchen Geschossansetzers ergibt sich eine kompakt bauende Konstruktion. Die Bauteile des Geschossansetzers müssen nicht bis in den Bereich unter dem Waffenrohr reichen. Die Geschwindigkeiten des Mitnehmers sowie der Ansetzkette addieren sich, wodurch sich eine hohe Ansetzgeschwindigkeit erreichen lässt.The use of such a bullet attachment results in a compact design. The components of the bulldozer do not have to reach into the area under the gun barrel. The speeds of the driver and the Ansetzkette add up, which can achieve a high Ansetzgeschwindigkeit.

In konstruktiver Ausgestaltung der Waffe wird ferner vorgeschlagen, dass der Geschossansetzer über ein Handhabungselement schwenkbeweglich gegenüber dem Waffenrohr angeordnet ist. Über das Handhabungselement kann der Ansetzer in eine mit dem Waffenrohr fluchtende Stellung geschwenkt werden, von welcher aus das Geschoss dann angesetzt werden kann, wonach das Handhabungselement den Geschossansetzer aus der Stellung hinter dem Waffenrohr wegschwenkt und der Waffenrücklauf freigegeben wird.In a constructive embodiment of the weapon is also proposed that the bulldozer is arranged pivotably via a handling element with respect to the gun barrel. About the handling element, the piecing can be pivoted into a position aligned with the gun barrel, from which the projectile can then be attached, after which the handling element wegschwenkt the bulldozer from the position behind the barrel and the weapon return is released.

Beim Ausführungsbeispiel sind sowohl die Führungselemente 8.5, 8.6 wie auch die an den Rollen 3.1, 3.2 vorgesehenen Ausnehmungen von V-förmiger bzw. dreieckiger Geometrie. Beim Ausführungsbeispiel sind jeweils zwei Rollen 3.1, 3.2 auf beiden Seiten des Mitnehmers 3 angeordnet. Es können jedoch auch mehr Rollen vorgesehen werden.in the region of the opening 9 of the Ansetzkette 2 entraining driver 3 can be seen. The driver 3 is designed in the manner of a rolling carriage, which is movable in the direction of the weapon via a drive element 5 designed as a linear drive in the exemplary embodiment. The movements of the driver 3 are guided in the region of the guide section 3.3 via freely rotatably mounted rollers 3.1, 3.2 relative to the charging tray 8. For this purpose, the rollers 3.1, 3.2 with the geometry of the provided on the charging tray 8 guide elements 8.5, 8.6 correspondingly designed, circumferential recesses. In the embodiment, both the guide elements 8.5, 8.6 as well as provided on the rollers 3.1, 3.2 recesses of V-shaped or triangular geometry. In the embodiment, two rollers 3.1, 3.2 are arranged on both sides of the driver 3 in each case. However, more roles may be provided.

Die Rollen 3.1, 3.2 sind innerhalb U-förmiger Ausnehmungen des Mitnehmers 3 in dessen Führungsabschnitt 3.3 frei drehbar gelagert. An den Führungsabschnitt 3.3 des Mitnehmers 3 schließt sich nach oben hin betrachtet ein Umlenkabschnitt 3.4 für die in dem Umlenkabschnitt 3.4 liegende Ansetzkette 2 an. Wie insbesondere die Darstellung in Fig. 2 erkennen lässt, weist der Umlenkabschnitt 3.4 einen 180°-Bogen auf, in welchem die Richtung der Ansetzkette 2 entsprechend umgelenkt wird, vgl. auch Fig. 4 und 5. Der Umlenkabschnitt 3.4 ist von Kanalförmiger Geometrie. Der Umlenkabschnitt 3.4 bildet eine Führung für die über ein Antriebselement 4 angetriebene Bewegung der Ansetzkette 2.The rollers 3.1, 3.2 are freely rotatably mounted within U-shaped recesses of the driver 3 in the guide section 3.3. At the guide section 3.3 of the driver 3, viewed at the top, there is a deflection section 3.4 for the attachment chain 2 lying in the deflection section 3.4. As in particular the representation in Fig. 2 can recognize, the deflection section 3.4 a 180 ° bend, in which the direction of Ansetzkette 2 is deflected accordingly, see. also Fig. 4 and 5 , The deflection section 3.4 is of channel-shaped geometry. The deflection section 3.4 forms a guide for the movement of the Ansetzkette 2 driven by a drive element 4.

Die Mitnahme der Ansetzkette 2 bei einer Bewegung des Mitnehmers 3 erfolgt über das Mitnahmeelement 4, welches nach Art eines Ritzels seitlich in die Ansetzkette 2 eingreift, vgl. auch Fig. 6. Das Mitnahmeelement ist gleichzeitig auch das Antriebselement 4 zum Antrieb der Ansetzkette 2, dem insoweit eine Doppelfunktion zukommt.The entrainment of Ansetzkette 2 in a movement of the driver 3 via the driving element 4, which engages in the manner of a pinion laterally in the Ansetzkette 2, see. also Fig. 6 , The entrainment element is at the same time also the drive element 4 for driving the Ansetzkette 2, to which extent plays a dual role.

Durch eine Rotation des Antriebselements 4 wird die Ansetzkette 2 in eine translatorische Bewegung in Richtung des Geschosses 6 bewegt. Über ein Druckstück 10 wird die Bewegung der als Schubkette ausgebildeten Ansetzkette 2 auf das Geschoss 6 übertragen, wodurch dieses in Richtung der Waffe aus der Ladeschale 8 geschoben wird. Die Ansetzkette 2 ist zu diesem Zweck derart ausgebildet, dass sie sich unter Einwirkung stauchender Längskräfte starr verhält, während sie sich gegenüber Querkräften nachgiebig verhält und daher innerhalb des gekrümmten Abschnitts 3.4 des Mitnehmers 3 geführt werden kann. Deshalb wird die Ansetzkette 2 als eine rückensteife Schubkette ausgeführt.By a rotation of the drive element 4, the Ansetzkette 2 is moved in a translational movement in the direction of the projectile 6. About a pressure piece 10, the movement of the trained as a push chain Ansetzkette 2 is transmitted to the projectile 6, whereby this is pushed in the direction of the weapon from the charging tray 8. The Ansetzkette 2 is designed for this purpose so that it behaves rigidly under the action of upsetting longitudinal forces, while it behaves resiliently to transverse forces and therefore can be guided within the curved portion 3.4 of the driver 3. Therefore, the Ansetzkette 2 is designed as a back-rigid push chain.

Durch die Umlenkung der Ansetzkette 2 ergibt sich eine parallele Anordnung des nachlaufenden Endes der Ansetzkette 2 und dem Geschoss 6 bzw. dem in Geschossrichtung bewegten vorderen Ende der Ansetzkette 2. Es ergibt sich eine kompakte, in Geschosslängsrichtung kurz bauende Konstruktion.The deflection of the Ansetzkette 2 results in a parallel arrangement of the trailing end of Ansetzkette 2 and the projectile 6 and the moving in the projectile direction front end of the Ansetzkette 2. It results in a compact, short in projectile longitudinal construction.

Wie die Darstellungen insbesondere in Fig. 3 und Fig. 6 erkennen lassen, sind die Bewegungen des ersten Antriebselements 4 zum Antrieb der Ansetzkette 2 und des zweiten Antriebselements 5 zum Antrieb des Mitnehmers 3 über ein Übertragungselement 7 miteinander gekoppelt. Das Übertragungselement 7 weist eine mit dem Antriebselement 4 verbundene Welle 7.1 auf. An dem dem ersten Antriebselement 4 gegenüberliegenden Ende weist die Welle 7.1 ein Ritzel 7.2 auf, welches mit dem an der Ladeschale 8 vorgesehenen Zahnstangenabschnitt 8.7 kämmt. Bei einer Linearbewegung des Mitnehmers 3, getrieben über das Antriebselement 5, rollt das Ritzel 7.2 auf dem Zahnstangenabschnitt 8.7 ab. Gemeinsam mit der Drehbewegung des Ritzels 7.2 beginnt die Welle 7.1 und mit dieser das erste Antriebselement 4 zu Drehen, wodurch die Ansetzkette 2 in Richtung des Geschosses 6 gefördert wird und dieses in Richtung der Waffe befördert wird.As the representations in particular in Fig. 3 and Fig. 6 can be seen, the movements of the first drive element 4 for driving the Ansetzkette 2 and the second drive element 5 are coupled to drive the driver 3 via a transmission element 7 with each other. The transmission element 7 has a shaft 7.1 connected to the drive element 4. At the end opposite the first drive element 4, the shaft 7.1 has a pinion 7.2, which meshes with the toothed rack section 8.7 provided on the charging shell 8. In a linear movement of the driver 3, driven by the drive element 5, the pinion 7.2 rolls on the rack section 8.7. Together with the rotational movement of the pinion 7.2, the shaft begins to rotate 7.1 and with this the first drive element 4, whereby the Ansetzkette 2 is conveyed in the direction of the projectile 6 and this is conveyed in the direction of the weapon.

Einzelheiten des Ansetzvorgangs werden nachfolgend im Einzelnen beschrieben.Details of the piecing process will be described in detail below.

Um ein in der Ladeschale 8 befindliches Geschoss 6 aus der Ladeschale 8 in dessen Ansetzstellung innerhalb des Waffenrohres zu befördern, wird das Handhabungselement 20 zunächst in eine Position hinter der Waffe verschwenkt, in welcher die Achse des Geschosses 6 mit der Rohrseelenachse des Waffenrohres fluchtet.To convey a bullet 6 located in the loading tray 8 out of the loading tray 8 in its setting position within the weapon barrel, the handling element 20 is first pivoted to a position behind the weapon, in which the axis of the bullet 6 is aligned with the tube axis of the barrel.

Anschließend wird das als Linearantrieb ausgebildete erste Antriebselement 5 mit Energie versorgt, was im Falle eines elektrischen Antriebselements 5 durch Bestromung erfolgen kann. Hierdurch wird der Mitnehmer 3 translatorisch in Richtung der Geschossachse des Geschosses 6 mit einer ersten Geschwindigkeit V1 bewegt, vgl. Fig. 6. Dabei rollen die Rollen 3.1, 3.2 an den Führungselementen 8.5, 8.6 der Ladeschale 8 ab. Bei der Bewegung des Mitnehmers 3 wird die Ansetzkette 2 über das seitlich zwischen den Gliedern der Ansetzkette 2 angreifende Antriebselement 4 mitgenommen.Subsequently, the trained as a linear drive first drive element 5 is supplied with energy, which can be done in the case of an electric drive element 5 by energization. As a result, the driver 3 is moved translationally in the direction of the projectile axis of the projectile 6 at a first speed V 1 , cf. Fig. 6 , The rollers 3.1, 3.2 roll on the guide elements 8.5, 8.6 of the charging tray 8. During the movement of the driver 3, the Ansetzkette 2 is taken over the laterally engaging between the links of Ansetzkette 2 drive element 4.

Gleichzeitig wird die Ansetzkette 2 über das auf dem Mitnehmer 3 mitfahrend angeordnete Antriebselement 4 mit einer Geschwindigkeit V2 in Richtung des Geschosses 6 bewegt, so dass sich eine Ansetzgeschwindigkeit Vgesamt ergibt, die gleich der Summe der Einzelgeschwindigkeiten V1 und V2 ist.At the same time the Ansetzkette 2 is moved over the driving on the driver 3 arranged driving element 4 at a speed V 2 in the direction of the projectile 6, so that a total Ansetzgeschwindigkeit V results, which is equal to the sum of the individual speeds V 1 and V 2 .

Die Bewegung des mitfahrenden Antriebselements 4 ist dabei über das Übertragungselement 7 an die Bewegung des ortsfesten Antriebselements 5 gekoppelt. Die über das als Linearantrieb ausgebildete Antriebselement 5 erfolgende Linearbewegung des Mitnehmers 3 wird über das mit dem Mitnehmer mitfahrende Ritzel 7.2 in eine Rotationsbewegung der Welle 7.1 und damit des Antriebselements 4 überführt, wodurch dann die Ansetzkette 2 in Richtung der Achse des Geschosses 6 gefördert wird.The movement of the co-driving drive element 4 is coupled via the transmission element 7 to the movement of the stationary drive element 5. The linear motion of the driver 3 taking place via the drive element 5 designed as a linear drive is converted via the pinion 7.2 traveling along with the driver into a rotational movement of the shaft 7.1 and thus of the drive element 4, whereby then the Ansetzkette 2 is conveyed in the direction of the axis of the projectile 6.

Beim Ausführungsbeispiel sind die Verhältnisse der Geschwindigkeiten V1, V2 derart gewählt, dass die Ansetzgeschwindigkeit der Kette V2 der Geschwindigkeit V1 des Mitnehmers 3 entspricht. Damit ergibt sich eine Gesamtgeschwindigkeit Vgesamt, die gleich der zweifachen der Einzelgeschwindigkeit des Mitnehmers 3 bzw. der Ansetzkette 2 ist. Durch Anpassung des Ritzels 8.7 bzw. des Antriebselements 4 sind jedoch auch andere Über- bzw. Untersetzungen dieses Geschwindigkeitsverhältnisses möglich.In the exemplary embodiment, the ratios of the speeds V 1 , V 2 are selected such that the attachment speed of the chain V 2 corresponds to the speed V 1 of the carrier 3. This results in a total speed V total , which is equal to twice the individual speed of the driver 3 and the Ansetzkette 2. By adapting the pinion 8.7 or the drive element 4, however, other over- or reductions of this speed ratio are possible.

Nachdem auf diese Weise das Geschoss 6 in die Ansetzstellung befördert wurde, verschwenkt das Handhabungselement 20 den Ansetzer 1 aus der Stellung hinter dem Rohr der Waffe, um den Waffenrücklauf freizugeben. Sodann kann das Geschoss 6, ggf. nach Einschub einer bestimmten Anzahl von Treibladungen, verschossen werden. Die entsprechenden Treibladungen können nach dem Ansetzen des Geschosses 6 ebenfalls mittels des Geschossansetzers 1 in das Rohr der Waffe befördert werden.After the projectile 6 has been conveyed into the Ansetzstellung in this way, the handling element 20 pivots the piecing 1 from the position behind the tube of the weapon to release the weapon return. Then the projectile 6, possibly after inserting a certain number of propellant charges, are fired. The corresponding propellant charges can also be conveyed by means of the bullet 1 in the pipe of the weapon after the attachment of the projectile 6.

Die Ausbildung des ersten Antriebselements 4 als mit dem Mitnehmer 3 mitfahrendes Antriebselement erlaubt eine kompakte Bauweise des Geschossansetzers 1, bei welchem sich eine erhöhte, aus der Geschwindigkeit der Ansetzkette 2 und der Geschwindigkeit des Mitnehmers 3 additiv zusammengesetzte Ansetzgeschwindigkeit Vgesamt ergibt.The design of the first drive element 4 as a drive element driving along with the driver 3 allows a compact construction of the bullet tappet 1, in which an increased rate of attachment V additively composed from the speed of the attachment chain 2 and the speed of the driver 3 results overall .
