Abstract

The military equipment comprises a turret mounted for rotation about a vertical axis and supporting, by means of a swivelling device with horizontal axis, a main heavy gun totally external to the turret, having its own shield and situated approximately in a plane passing through the axis of rotation of the turret. The swivelling device comprises two lateral supports surrounding the gun and supporting the latter via bearings so as to define an elevation axis situated behind the rotational axis of the turret. One of the supports and the shield of the gun have oppositely situated openings for forming a protected channel for a gun loading system supplying the gun with rounds of ammunition from inside the turret. The feed system constitutes a unitary assembly. It has a frame secured in the gun shield on which a carriage is transversely movable between a position where an ammunition craddle supported by the carriage is aligned with a weapon and a position lateral to the weapon. The loading craddle is movable between a rear position for transport by the carriage and a front position accessible from inside the turret for placing a piece of ammunition therein.

Description

L'invention est relative aux matériels militaires du genre décrit dans EP-A1-0 023 441 comportant selon le préambule de la revendication 1, une tourelle montée de façon à pouvoirtourner autour d'un axe vertical et portant, par un dispositif de tourillonnement à axe horizontal, une arme principale lourde totalement extérieure à la tourelle, munie d'un blindage propre et située approximativement dans un plan passant par l'axe de rotation de la tourelle, le dispositif de tourillonnement comprenant deux supports latéraux encadrant l'arme et recevant des tourillons portés par celle-ci (ou la pièce la reliant aux supports latéraux) pour définir un axe de tourillonnement en site situé en arrière de l'axe de rotation de la tourelle, l'un des supports et le blindage de l'arme ayant des ouvertures en regard pour constituer un couloir d'alimentation protégé pour un système d'approvisionnement coup par coup de l'arme en munitions depuis l'intérieur de la tourelle.The invention relates to military equipment of the kind described in EP-A1-0 023 441 comprising, according to the preamble of claim 1, a turret mounted so as to be able to rotate about a vertical axis and carrying, by a journaling device with horizontal axis, a heavy main weapon completely external to the turret, provided with its own armor and situated approximately in a plane passing through the axis of rotation of the turret, the journaling device comprising two lateral supports framing the weapon and receiving journals carried by this one (or the part connecting it to the lateral supports) to define an axis of journaling in elevation located behind the axis of rotation of the turret, one of the supports and the armor of the weapon having opposite openings to constitute a protected supply corridor for a shot-by-shot supply system of the weapon in ammunition from inside the turret.

Cette disposition présente de nombreux avantages. En contrepartie, elle exige de faire suivre, à chaque munition à son tour, un trajet défini. Un système d'approvisionnement donné à titre d'exemple non limitatif dans EP-A1-0 023 441 comprend un convoyeur traversant l'un des supports et permettant d'amener une à une les munitions d'un poste de chargement manuel, situé en tourelle, à un poste de transfert situé dans le blindage propre de l'arme principale, d'où il est repris par un mécanisme de décalage latéral, puis d'introduction axiale de la munition dans l'arme. En contrepartie de la commodité qu'offre cette disposition pour le servant de l'arme, elle exige un convoyeur capable d'accepter des modifications importantes de la position du poste de transfert par rapport au poste de chargement manuel.This arrangement has many advantages. In return, it requires that each munition in turn follow a defined route. A supply system given by way of nonlimiting example in EP-A1-0 023 441 comprises a conveyor passing through one of the supports and making it possible to bring the munitions one by one to a manual loading station, located in turret, at a transfer station located in the armor of the main weapon, from where it is taken up by a lateral shift mechanism, then axial introduction of the ammunition into the weapon. In return for the convenience offered by this arrangement for the servant of the weapon, it requires a conveyor capable of accepting significant changes in the position of the transfer station relative to the manual loading station.

L'invention vise à fournir un matériel militaire du genre ci-dessus défini comportant un système d'approvisionnement de constitution relativement simple, pouvant tolérer de grands débattements en site de l'arme, de montage facile, permettant de transférer la munition, placée dans un berceau d'une position latérale avant accessible depuis l'intérieur de la tourelle à une position arrière de chargement dans l'axe de l'arme et en arrière de celle-ci.The invention aims to provide military equipment of the kind defined above comprising a relatively simple constitution supply system, capable of tolerating large deflections in site of the weapon, of easy assembly, making it possible to transfer the ammunition, placed in a cradle from a front lateral position accessible from the inside of the turret to a rear loading position in the axis of the weapon and behind it.

Dans ce but, l'invention se réfère à un matériel dont le système d'approvisionnement constitue un ensemble intégré destiné à être placé à l'intérieur du blindage de l'arme dans lequel selon la partie caractérisante de la revendication 1, le berceau est constitué d'un tube porté par un chariot solidaire de deux coulisseaux qui peuvent se déplacer sur des glissières transversales appartenant à une platine fixée au blindage de l'arme, sous l'action de moyens de déplacement transversal, des moyens de déplacement du berceau, d'avant en arrière, et réciproquement étant prévus pour permettre à celui-ci de se déplacer longitudinalement par rapport au chariot, et dans lequel des moyens portés par le berceau permettent de repousser la munition dans l'arme lorsque le berceau est aligné avec elle.For this purpose, the invention refers to a material whose supply system constitutes an integrated assembly intended to be placed inside the armor of the weapon in which according to the characterizing part of claim 1, the cradle is consisting of a tube carried by a carriage integral with two slides which can move on transverse slides belonging to a plate fixed to the armor of the weapon, under the action of transverse displacement means, means of displacement of the cradle, back and forth, and vice versa being provided to allow the latter to move longitudinally relative to the carriage, and in which means carried by the cradle allow the ammunition to be pushed back into the weapon when the cradle is aligned with it .

Le berceau est avantageusement constitué par un tube ouvert suivant une génératrice dont les extrémités sont suspendues à une chaîne de déplacement et de basculement de l'avant vers l'arrière, tube muni de moyens pour retenir la munition dans le tube.The cradle is advantageously constituted by an open tube along a generator, the ends of which are suspended from a movement and tilting chain from front to rear, a tube provided with means for retaining the ammunition in the tube.

L'invention sera mieux comprise à la lecture de la description qui suit d'un mode particulier de réalisation, donné à titre d'exemple non limitatif.The invention will be better understood on reading the following description of a particular embodiment, given by way of non-limiting example.

La description se réfère aux dessins qui l'accompagnent, dans lesquels :

  • La figure 1 est une vue fantôme en perspective, montrant la disposition relative des supports de l'arme et du blindage de cette dernière, ainsi que le système d'approvisionnement dans l'état où il se trouve juste avant chargement de la munition dans l'arme.
  • La figure 1A est une vue en coupe suivant un plan passant par l'axe des tourillons de l'arme de la Figure 1 ;
  • Les figures 2 et 3 sont des vues de détail en perspective montrant respectivement un exemple de chariot type du système d'approvisionnement en position latérale et en position axiale ;
  • La figure 4 est une vue d'ensemble d'une tourelle équipée d'un système d'approvisionnement suivant l'invention.
The description refers to the accompanying drawings, in which:
  • Figure 1 is a phantom perspective view, showing the relative arrangement of the supports of the weapon and the shielding of the latter, as well as the supply system in the state it is in just before loading the ammunition in the 'armed.
  • Figure 1A is a sectional view along a plane passing through the axis of the pins of the weapon of Figure 1;
  • Figures 2 and 3 are detailed perspective views respectively showing an example of a typical carriage of the supply system in the lateral position and in the axial position;
  • Figure 4 is an overview of a turret equipped with a supply system according to the invention.

Le système d'approvisionnement qui sera maintenant décrit à titre d'exemple en faisant référence aux Figures 1 à 3 constitue un ensemble intégré comportant une platine de montage sur la paroi interne du blindage de l'arme, pouvant être construit et réglé indépendamment de l'arme. Le système d'approvisionnement est utilisable notamment sur une tourelle de véhicule blindé du genre montré en Figure 4, similaire à celle décrite dans la demande de brevet FR 7919401. Cette tourelle comporte une couronne 10 de rotation de la tourelle autour d'un axe vertical. Elle est munie de deux supports verticaux 12 encadrant une arme principale 14 de moyen ou de gros calibre, imposant un chargement coup par coup, munie d'un blindage propre 16. L'axe de tourillonnement en site de l'arme est défini par deux tourillons 18 dont elle est munie et qui tournent dans des paliers non représentés, prévus dans les supports 12.The supply system which will now be described by way of example with reference to FIGS. 1 to 3 constitutes an integrated assembly comprising a mounting plate on the internal wall of the armor of the weapon, which can be constructed and adjusted independently of the 'armed. The supply system can be used in particular on an armored vehicle turret of the type shown in FIG. 4, similar to that described in patent application FR 7919401. This turret comprises a crown 10 for rotating the turret about a vertical axis . It is provided with two vertical supports 12 framing a main weapon 14 of medium or large caliber, imposing a load blow by blow, provided with its own shielding 16. The axis of journaling in site of the weapon is defined by two pins 18 which it is provided with and which rotate in bearings not shown, provided in the supports 12.

Le chargement coup par coup de l'arme en munitions stockées sous tourelle s'effectue par l'intermédiaire de l'un des supports 12, creux et de largeur interne suffisante pour que le servant placé en tourelle puisse y introduire la munition qu'il a prélevée à l'un des emplacements de stockage répartis dans la tourelle. Un passage protégé entre support 12 et blindage 16 est constitué par des ouvertures coopérantes 20 ménagées dans les faces en regard et de développement angulaire suffisant pour présenter un recouvrement quel que soit le pointage en site de l'arme.The loading step by step of the weapon in ammunition stored under turret is carried out by the intermediary of one of the supports 12, hollow and of sufficient internal width so that the servant placed in turret can introduce the ammunition which he took at one of the storage locations distributed in the turret. A protected passage between support 12 and shield 16 is formed by cooperating openings 20 formed in the facing faces and of sufficient angular development to present an overlap whatever the pointing in site of tear.

Le système d'approvisionnement, placé dans le blindage 16, comporte une platine fixe (non représentée) destinée à être fixée au blindage, munie d'au moins deux glissières 22 qui sont horizontales lorsque l'axe de la tourelle est vertical. Ces deux glissières 22, rectilignes (cas des figures) ou non, peuvent être orthogonales à l'axe de l'arme 14 ou non. Elles portent des coulisseaux 24 appartenant à un chariot 26 et permettant au chariot de se déplacer entre une position axiale (Figures 1 et 3) et une position latérale (Figure 2). Lorsque le chariot 26 est dans sa position axiale, un berceau en forme de tube 28 qu'il porte est coaxial à l'arme. Lorsqu'il est en position latérale. le chariot dégage l'espace nécessaire au recul de l'arme et, éventuellement, à l'éjection de la douille ou de la munition inutilisable.The supply system, placed in the shield 16, comprises a fixed plate (not shown) intended to be fixed to the shield, provided with at least two slides 22 which are horizontal when the axis of the turret is vertical. These two slides 22, rectilinear (case of the figures) or not, can be orthogonal to the axis of the weapon 14 or not. They carry slides 24 belonging to a carriage 26 and allowing the carriage to move between an axial position (Figures 1 and 3) and a lateral position (Figure 2). When the carriage 26 is in its axial position, a tube-shaped cradle 28 which it carries is coaxial with the weapon. When in the lateral position. the carriage clears the space necessary for the recoil of the weapon and, possibly, for the ejection of the casing or of the unusable ammunition.

Un mécanisme moteur est prévu pour déplacer Je chariot 26 entre ces deux positions. Ce mécanisme (Figure 3) comporte une chaîne sans fin 30 passant sur quatre pignons 32 dont les axes sont parallèles, disposés aux quatre coins d'un rectangle et solidaires des glissières 22. L'un de ces pignons est muni d'un organe d'entraînement (non représenté) tel qu'un motoréducteur électrique, tandis que les autres pignons n'ont qu'un rôle de guidage. La chaîne 30 porte un doigt d'entraînement 36 destiné à circuler dans une traverse 38 reliant les coulisseaux 24, généralement perpendiculaire à ces coulisseaux. La position de ce doigt d'entraînement 36 définit la position du chariot.A motor mechanism is provided for moving the carriage 26 between these two positions. This mechanism (Figure 3) comprises an endless chain 30 passing over four sprockets 32 whose axes are parallel, arranged at the four corners of a rectangle and integral with the slides 22. One of these sprockets is provided with a member drive (not shown) such as an electric geared motor, while the other pinions have only a guiding role. The chain 30 carries a drive finger 36 intended to circulate in a cross member 38 connecting the slides 24, generally perpendicular to these slides. The position of this drive finger 36 defines the position of the carriage.

Le chariot 26 comprend, en plus des coulisseaux 24 et de la traverse 38, une structure support du berceau tubulaire 28. Dans le mode de réalisation représenté, cette structure comporte des plaques latérales 40 supports de mécanisme, fixées par des plaques 42 aux coulisseaux 24, et un étrier 44 fixé aux plaques 40. Le berceau 28 est suspendu à l'étrier 44 par au moins une chaîne 46 qui lui permet de basculer dans un plan vertical entre les positions montrées en traits pleins et en tirets sur la Figure 2. La chaîne 46 passe sur un pignon 48 porté par un axe perpendiculaire au berceau 28, pignon porté par l'étrier 44 à l'avant du chariot. Les extrémités de la chaîne sont fixées, l'une à l'avant et l'autre à l'arrière du berceau 28. Cette chaîne est disposée de façon à permettre au berceau tubulaire de descendre dans la tourelle lorsqu'il avance. Au lieu de prévoir la chaîne de suspension 46 ou en adjonction à cette chaîne, on peut prévoir des guides avant convergents 58 destinés à recevoir des pions 60 fixés à l'avant du berceau tubulaire 28 (dont une représentation partielle est donnée).The carriage 26 comprises, in addition to the slides 24 and the cross member 38, a support structure for the tubular cradle 28. In the embodiment shown, this structure includes side plates 40 mechanism supports, fixed by plates 42 to the slides 24 , and a stirrup 44 fixed to the plates 40. The cradle 28 is suspended from the stirrup 44 by at least one chain 46 which allows it to switch in a vertical plane between the positions shown in solid lines and in dashes in FIG. 2. The chain 46 passes over a pinion 48 carried by an axis perpendicular to the cradle 28, pinion carried by the stirrup 44 at the front of the carriage. The ends of the chain are fixed, one at the front and the other at the rear of the cradle 28. This chain is arranged so as to allow the tubular cradle to descend into the turret as it advances. Instead of providing the suspension chain 46 or in addition to this chain, it is possible to provide converging front guides 58 intended to receive pins 60 fixed to the front of the tubular cradle 28 (a partial representation of which is given).

Les mouvements du berceau 28 vers l'avant et vers l'arrière sont commandés par deux chaînes de commande 62 placées, l'une à droite, l'autre à gauche, du berceau. Ces chaînes sont reliées au berceau par des supports 64. Les chaînes peuvent être guidées dans une gouttière 66 formant glissière ou munies de supports à galets et entraînées par des pignons 67. Les mouvements de descente et montée (avance ou recul) du berceau 28 peuvent être assurés par commande d'un des pignons 67 des chaînes 62, avec ou sans liaison mécanique entre les pignons homologues des deux chaînes 62. Les chaînes 62 peuvent par ailleurs être remplacées par un vérin de commande des supports 64, constituant des demi-axes se déplaçant dans des glissières.The movements of the cradle 28 forwards and backwards are controlled by two control chains 62 placed, one on the right, the other on the left, of the cradle. These chains are connected to the cradle by supports 64. The chains can be guided in a gutter 66 forming a slide or provided with roller supports and driven by sprockets 67. The movements of descent and ascent (advance or retreat) of the cradle 28 can be ensured by controlling one of the sprockets 67 of the chains 62, with or without a mechanical connection between the homologous sprockets of the two chains 62. The chains 62 can moreover be replaced by a jack for controlling the supports 64, constituting half-axes moving in slides.

Le berceau est également muni de moyens permettant de retenir en place la munition 52 et des moyens pour repousser la munition vers l'avant et l'introduire dans l'arbre. Les moyens de verrouillage peuvent être constitués par un verrou arrière 68 (Figures 2 et 3) à désarmement automatique lors de l'introduction. Les moyens de chargement de la munition dans l'arme, alors que le berceau 28 est en position axiale, comportent une chaîne de chargement 70 tendue sur des pignons 72 tournant sur le berceau. L'un des pignons 72 est muni d'un moteur d'entraînement. La chaîne de chargement 70 porte un doigt 74 (Figure 3) destiné à faire glisser la munition vers l'avant dans le berceau 28. L'arrivée de ce doigt de chargement 74 à l'arrière de la munition provoque le désarmement du verrou 68 immobilisant la munition dans le berceau. Un microrupteur ou un détecteur de proximité (non représenté) est prévu sur le berceau 28 pour arrêter la chaîne de chargement lorsque la munition a été introduite dans l'arme. Le doigt 74 peut être monté sur un vérin d'axe voisin de la chaîne sans fin 70.The cradle is also provided with means making it possible to hold the munition 52 in place and means for pushing the ammunition forward and introducing it into the tree. The locking means can be constituted by a rear lock 68 (Figures 2 and 3) with automatic disarming during introduction. The means for loading the ammunition into the weapon, while the cradle 28 is in the axial position, comprise a loading chain 70 stretched on pinions 72 rotating on the cradle. One of the pinions 72 is provided with a drive motor. The loading chain 70 carries a finger 74 (Figure 3) intended to slide the ammunition forward in the cradle 28. The arrival of this loading finger 74 at the rear of the ammunition disarms the lock 68 immobilizing the ammunition in the cradle. A microswitch or a proximity detector (not shown) is provided on the cradle 28 to stop the loading chain when the ammunition has been introduced into the weapon. The finger 74 can be mounted on a cylinder with an axis close to the endless chain 70.

La séquence de fonctionnement du système d'approvisionnement qui vient d'être décrit peut être considérée comme comportant trois phases qui seront successivement décrites.The operating sequence of the supply system which has just been described can be regarded as comprising three phases which will be successively described.

La première phase comporte la mise en place de la munition dans le berceau tubulaire de chargement par le servant et la remontée de cette munition dans le compartiment canon, délimité par le blindage de l'arme. Le berceau étant dans la position montrée en tirets sur la Figure 2, le servant engage la munition dans le berceau tubulaire jusqu'à ce que le verrou 68 s'incliquète. Cette opération peut s'effectuer quel que soit le pointage en site de l'arme, du moins dans une plage prédéterminée. Le moteur d'entraînement des chaînes 62 est alimenté pour faire reculer et basculer le berceau 28 et l'amener dans la position montrée en traits pleins sur la Figure 2. En règle générale, cette opération sera effectuée sur commande du servant. La suite des opérations pourra s'effectuer soit sous la commande d'un automatisme séquentiel, soit en réponse à des commandes individuelles fournies par le servant de l'arme. A l'issue de cette première phase, le berceau se trouve immobilisé sur le chariot par le verrou 50 qui s'engage automatiquement lors de l'arrivée du chariot en position arrière.The first phase involves the placement of the ammunition in the tubular loading cradle by the servant and the ascent of this ammunition in the barrel compartment, delimited by the armor of the weapon. The cradle being in the position shown in dashes in Figure 2, the servant engages the ammunition in the tubular cradle until the latch 68 clicks. This operation can be carried out whatever the pointing in site of the weapon, at least within a predetermined range. The chain drive motor 62 is powered to reverse and tilt the cradle 28 and bring it into the position shown in solid lines in Figure 2. Generally, this operation will be performed on command of the servant. The continuation of the operations can be carried out either under the command of a sequential automatism, or in response to individual commands provided by the servant of the weapon. At the end of this first phase, the cradle is immobilized on the carriage by the latch 50 which engages automatically when the carriage arrives in the rear position.

La seconde phase comporte le transfert latéral de la munition contenue dans son berceau et son maintien en place pendant le chargement. Au début de cette phase, le berceau tubulaire se trouve en position latérale. Le déplacement du chariot est effectué par mise en action du motoréducteur de commande de la chaîne 30. Cette dernière entraîne le doigt 36 qui amène le chariot 26 de la position latérale à la position axiale. Une fois arrivé dans la position axiale, le chariot 26 est verrouillé latéralement par le passage du doigt 36 sur un contact fixé à l'avant de la traverse 38. Puis le doigt est immobilisé ou ralenti dans la traverse pendant la troisième phase.The second phase involves the lateral transfer of the ammunition contained in its cradle and its maintenance in place during loading. At the start of this phase, the tubular cradle is in the lateral position. The movement of the carriage is carried out by actuation of the geared motor for controlling the chain 30. The latter drives the finger 36 which brings the carriage 26 from the lateral position to the axial position. Once in the axial position, the carriage 26 is locked laterally by the passage of the finger 36 on a contact fixed at the front of the cross member 38. Then the finger is immobilized or slowed down in the cross member during the third phase.

Cet arrêt du doigt de verrouillage 36 dans la traverse est provoqué par son passage devant un microrupteur ou un détecteur de proximité non représenté.This stopping of the locking finger 36 in the cross-member is caused by its passage in front of a microswitch or a proximity detector not shown.

La troisième phase est constituée par le chargement de la munition dans le canon, le chariot étant en position axiale. L'opération s'effectue par entraînement de la chaîne 70. Le doigt 74 de cette chaîne, initialement porté par le brin supérieur, vient prendre appui contre le fond de la munition et enfonce cette dernière dans l'arme.The third phase consists of loading the ammunition into the barrel, the carriage being in the axial position. The operation is carried out by driving the chain 70. The finger 74 of this chain, initially carried by the upper strand, comes to bear against the bottom of the ammunition and pushes the latter into the weapon.

Une fois le chargement effectué, le berceau doit être ramené dans sa position initiale par des mouvements inverses de ceux qui viennent d'être décrits. Le retour du chariot en position latérale s'effectue par déverrouillage latéral du chariot mobile, puis par le déplacement latéral du doigt 36 (vers la gauche du compartiment canon dans le cas illustré). Lorsque la traverse 38 est revenue en position latérale, le déplacement du doigt vers l'arrière verrouille de nouveau le chariot 26 dans le sens latéral. Le servant peut alors commander le basculement du berceau, le désarmement du verrou 50 s'effectuant lors de la commande du motoréducteur agissant sur le (ou les) pignon(s) moteur(s) 67.Once the loading is completed, the cradle must be returned to its initial position by reverse movements to those just described. The return of the carriage to the lateral position is effected by lateral unlocking of the mobile carriage, then by the lateral displacement of the finger 36 (to the left of the barrel compartment in the case illustrated). When the crosspiece 38 has returned to the lateral position, the movement of the finger backwards again locks the carriage 26 in the lateral direction. The servant can then control the tilting of the cradle, the disarming of the lock 50 being effected during the command of the geared motor acting on the motor pinion (s) 67.

Dans cette nouvelle position, une nouvelle munition peut être mise en place dans le berceau, la séquence de rechargement ne devant toutefois être entreprise qu'après tir ou éjection de la munition en place.In this new position, a new munition can be put in place in the cradle, the reloading sequence only having to be undertaken after firing or ejecting the ammunition in place.

On voit que la munition prend successivement les positions indiquées sur la Figure 4 en 1 (prélèvement manuel), 2 (élévation, quel que soit le site), 3 (transfert vers l'axe du canon accompagné de l'éjection de la douille précédente en 5), et 4 (introduction).We see that the ammunition successively takes the positions shown in Figure 4 in 1 (manual sampling), 2 (elevation, whatever the site), 3 (transfer to the axis of the barrel accompanied by the ejection of the previous casing in 5), and 4 (introduction).
