Description

Objet de l'inventionObject of the invention

Le domaine technique de l'invention est celui des systèmes de chargement automatique de canons de gros calibres (75 mm à 140 mm) avec des munitions, équipant les véhicules blindés et chars de combat. La présente invention se rapporte plus particulièrement à un dispositif pour amener la munition depuis la zone de stockage jusqu'à la chambre du canon.The technical field of the invention is that of automatic loading systems large guns (75 mm to 140 mm) with ammunition, equipping the armored vehicles and battle tanks. The present invention relates more particularly to a device for bringing the munition from the storage area to the barrel chamber.

Arrière-plan technologique et état de la techniqueTechnological background and state of the art

Sur les véhicules blindés et chars de combat, la phase de transport de la munition depuis la zone de stockage jusqu'au canon se fait durant le déplacement du véhicule, le cas échéant sur un terrain accidenté, ce qui génère vibrations et chocs. Dès lors, une difficulté importante rencontrée dans cette phase est le maintien correct de la munition durant son amenée vers le canon. Ce maintien doit être suffisamment rigide afin d'assurer:

  • la sécurité des membres de l'équipage qui se situent potentiellement à proximité immédiate de la zone de chargement;
  • le respect de l'intégrité et la conservation des propriétés physiques et des performances de la munition;
  • une insertion aisée, sûre et sans raté de la munition dans la chambre du canon.
On armored vehicles and tanks, the transport phase of the ammunition from the storage area to the barrel is done during the movement of the vehicle, if necessary on rough terrain, which generates vibrations and shocks. Therefore, an important difficulty encountered in this phase is the correct maintenance of the ammunition during its delivery to the barrel. This maintenance must be sufficiently rigid to ensure:
  • the safety of crew members potentially located in the immediate vicinity of the loading area;
  • the respect of the integrity and the conservation of the physical properties and performances of the ammunition;
  • an easy, safe and safe insertion of the ammunition into the barrel chamber.

Le maintien correct de la munition durant son amenée vers le canon conduit le plus souvent à la conception de dispositifs de transport de la munition constitués du fourreau sur lequel est posé la munition, le fourreau étant muni d'un mécanisme télescopique. Cette solution comporte plusieurs inconvénients:

  • la munition reposant en position naturelle dans le fourreau, son axe longitudinal n'est pas aligné sur l'axe du canon, ce qui s'avère problématique pour l'insertion dans la chambre du canon, en particulier avec des munitions dont la forme du projectile comporte une arête vive qui fait obstacle à l'entrée de la chambre;
  • le fourreau ayant un inévitable encombrement en hauteur sur toute la longueur de la munition, il interfère potentiellement avec le mécanisme du magasin de stockage, ce qui engendre des contraintes techniques supplémentaires. Ces contraintes sont typiquement solutionnées soit en équipant chaque loge de munition d'une goulotte individuelle, ce qui est pénalisant pour la masse de l'équipement, soit en réalisant le fourreau sous forme d'un mécanisme escamotable, plus complexe;
  • lors du chargement en conditions de roulage sévère, la munition, ne se trouvant pas fermement maintenue durant la phase d'amenée, bouge dans le plan vertical.
The correct maintenance of the ammunition during its delivery to the barrel usually leads to the design of ammunition transport devices consisting of the sleeve on which the ammunition is placed, the sleeve being provided with a telescopic mechanism. This solution has several disadvantages:
  • the ammunition resting in the natural position in the sheath, its longitudinal axis is not aligned with the axis of the barrel, which proves problematic for insertion into the barrel chamber, in particular with ammunition whose shape projectile has a sharp edge that obstructs the entrance of the room;
  • the sheath having an unavoidable congestion height over the entire length of the munition, it potentially interferes with the mechanism of the storage magazine, which generates additional technical constraints. These constraints are typically solved by equipping each ammunition box with an individual chute, which is penalizing for the mass of the equipment, or by producing the sheath in the form of a retractable mechanism, more complex;
  • when loading in severe driving conditions, the munition, not being firmly held during the feeding phase, moves in the vertical plane.

Il existe d'autres dispositifs de préhension de de la munition.There are other devices for gripping ammunition.

Le document DE2330889 A1 divulgue un système de chargement de munitions avec un dispositif de préhension muni de mâchoires montées pivotantes. La munition est portée à deux endroits par des rouleaux et prise par le dispositif de préhension dans le culot de la douille. L'inconvénient de ce système est que la munition est simplement appuyée sur les rouleaux et qu'elle est prise à un endroit hors du centre de gravité. Lors du chargement en conditions de roulage sévère, la munition ne se trouvant pas fermement maintenue durant la phase d'amenée, elle est susceptible de se déplacer dans le plan vertical.The document DE2330889 A1 discloses an ammunition loading system with a gripping device provided with pivotally mounted jaws. The ammunition is carried in two places by rollers and taken by the gripper in the base of the sleeve. The disadvantage of this system is that the ammunition is simply resting on the rollers and is taken out of the center of gravity. When loading in severe driving conditions, the munition not being held firmly during the feeding phase, it is likely to move in the vertical plane.

Le document WO 2006/051425 A2 divulgue un dispositif de manipulation d'armes pour transporter et charger des armes sur un avion ou d'autres véhicules. Le dispositif est muni d'une pince qui comporte des rouleaux destinés à être positionnés sur le pourtour de l'arme à maintenir. La pince à arme comporte en outre un lien amovible adapté pour déplacer au moins un des rouleaux depuis une première position où l'arme est maintenue en position par contact avec les rouleaux vers une deuxième position où le rouleau libère l'arme permettant son déplacement dans une direction transversale. Ce système a pour désavantage que la préhension s'effectue dans le magasin de munitions et qu'il nécessite une pince pour chaque munition stockée. De plus, le système à pince a pour désavantage qu'il ne permet pas de faire coulisser la munition selon un mouvement longitudinal nécessaire pour transporter une munition depuis le magasin vers la chambre du canon.The document WO 2006/051425 A2 discloses a weapon handling device for transporting and loading weapons on an aircraft or other vehicles. The device is provided with a clamp which comprises rollers intended to be positioned on the periphery of the weapon to be maintained. The weapon clamp further comprises a detachable link adapted to move at least one of the rollers from a first position where the weapon is held in position by contact with the rollers to a second position where the roll releases the weapon allowing its movement in a transverse direction. This system has the disadvantage that the gripping takes place in the ammunition store and requires a clamp for each stored ammunition. In addition, the clamp system has the disadvantage that it does not allow to slide the munition in a longitudinal movement necessary to transport a munition from the store to the barrel chamber.

Le document US 6,460,448 B1 divulgue un dispositif de chargement d'obus dans un mortier par la bouche. Ce dispositif comporte des moyens d'élévation de l'obus se déplaçant linéairement grâce à des guides et des mâchoires agrippant son pourtour. Arrivé à hauteur de la bouche, l'obus est translaté à l'aide d'un dispositif de transfert afin d'être positionné dans l'axe du mortier et inséré dans la bouche de ce dernier.The document US 6,460,448 B1 discloses a shell loading device in a mortar by the mouth. This device comprises elevation means of the shell moving linearly through guides and jaws gripping its periphery. Arrived at the height of the mouth, the shell is translated by means of a transfer device to be positioned in the axis of the mortar and inserted into the mouth of the latter.

But de l'inventionPurpose of the invention

L'invention a pour but de palier aux inconvénients cités ci-dessus en proposant une nouvelle solution technique permettant un maintien ferme de la munition durant l'entièreté de son trajet jusqu'à ce que le projectile soit en cours d'insertion dans la chambre du canon, et laissant libre la zone de défilement des munitions dans le magasin de stockage, tout en respectant les zones de préhension préconisées par les normes STANAGs.The invention aims to overcome the disadvantages mentioned above by proposing a new technical solution allowing the ammunition to be firmly held during its entire journey until the projectile is being inserted into the barrel chamber, leaving the ammunition scroll zone free in the magazine, while respecting the grip zones recommended by STANAGs standards.

Description générale de l'inventionGeneral description of the invention

La présente invention concerne un dispositif de préhension de la munition pouvant se déplacer longitudinalement depuis le magasin où sont stockées les munitions jusqu'à la chambre du canon.The present invention relates to a device for gripping the ammunition that can move longitudinally from the store where ammunition is stored to the barrel chamber.

Le dispositif de préhension selon l'invention et tel que partiellement montré aux figures 1 et 2 comporte plusieurs pattes 2 destinées à se positionner sur le périmètre de la douille de la munition 3 à proximité de son centre de gravité et à enserrer la douille sur une longueur suffisante pour empêcher tout basculement de la munition. Le positionnement des pattes est déterminé en fonction de la masse, de la position du centre de gravité et du moment d'inertie de la munition. Concrètement, les pattes couvrent une zone située entre 1/3 et 2/3 de la hauteur de la munition, cette zone pouvant être de longueur inférieure à un 1/3 de la hauteur de la munition. Les pattes sont espacées sur le périmètre de la douille de la munition et peuvent être, par exemple, au nombre de quatre espacées le long de quatre génératrices de la douille et, ce, de manière équidistante.The gripping device according to the invention and as partially shown to the Figures 1 and 2 has several tabs 2 intended to be positioned on the perimeter of the sleeve of the ammunition 3 near its center of gravity and to grip the sleeve to a length sufficient to prevent tilting of the munition. The positioning of the legs is determined according to the mass, the position of the center of gravity and the moment of inertia of the munition. Specifically, the legs cover an area between 1/3 and 2/3 of the height of the munition, this area may be less than 1/3 of the length of the ammunition. The tabs are spaced apart around the perimeter of the ammunition socket and may be, for example, four in number spaced along four generatrices of the socket and in an equidistant manner.

Selon l'invention, le dispositif de préhension est équipé d'un mécanisme de verrouillage/déverrouillage des pattes. Comme son nom l'indique, en position verrouillée, les pattes sont fixes alors qu'en position déverrouillée, elles sont libres de se déplacer radialement permettant un passage total de la munition dans sa direction longitudinale et, ce, dans les deux sens.According to the invention, the gripping device is equipped with a mechanism for locking / unlocking the tabs. As the name suggests, in locked position, the tabs are fixed while in the unlocked position, they are free to move radially allowing a total passage of the munition in its longitudinal direction and, in both directions.

Description détaillée de l'inventionDetailed description of the invention

Le dispositif de préhension selon l'invention comporte un support 1 muni d'une ouverture pour permettre le passage de la munition (fig.1 et 2). Les pattes de préhension 2 sont montées sur le support au sein de l'ouverture et peuvent se déplacer radialement entre une position de fermeture, dite de verrouillage et une position d'ouverture, dite de déverrouillage. En utilisation, comme expliqué ci-dessous, les pattes se déplacent conjointement entre la position de verrouillage et la position de déverrouillage.The gripping device according to the invention comprises a support 1 provided with an opening to allow the passage of the ammunition ( fig.1 and 2 ). The gripping tabs 2 are mounted on the support within the opening and can move radially between a locking position, said locking and an open position, called unlocking. In use, as explained below, the tabs move together between the locking position and the unlocking position.

Les pattes de préhension délimitent un espace de section circulaire avec un diamètre croissant visible à la figure 3. Ainsi, chaque patte de préhension présente une première partie 2a s'évasant vers une seconde partie 2b dans une direction s'étendant de la face avant du support, c.à.d. la face destinée à entrer en contact avec la culasse du canon, vers la face arrière du support. Cette première partie 2a comporte une surface de contact destinée à épouser la forme légèrement conique de la douille de la munition. La seconde partie 2b présente une forme plus évasée facilitant l'insertion de la munition dans les pattes.The gripping tabs delimit a space of circular section with an increasing diameter visible at the figure 3 . Thus, each gripping lug has a first portion 2a flaring towards a second portion 2b in a direction extending from the front face of the support, i.e. the face intended to come into contact with the breech of the barrel towards the rear face of the support. This first part 2a has a contact surface intended to match the slightly conical shape of the sleeve of the ammunition. The second part 2b has a more flared shape facilitating the insertion of the ammunition in the legs.

Le dispositif de préhension selon l'invention comporte un mécanisme de déverrouillage des pattes actionné par contact de doigts rétractables, dits de déverrouillage, avec un élément extérieur. Selon l'invention, les doigts rétractables 4 sont positionnés sur la face avant du support (fig.1). En utilisation, cette face bute contre la culasse du canon, ce qui, via la rétraction des doigts à l'intérieur du support, déclenche l'ouverture conjointe des pattes et permet à la munition d'entrer dans la chambre du canon. Selon le mode de réalisation de la figure 1, les doigts 4 situés à gauche et à droite déclenchent respectivement et indépendamment l'ouverture radiale des pattes situées à gauche et à droite. Différents systèmes peuvent être envisagés pour lier la rétraction des doigts 4 à l'expansion radiale des pattes. A titre d'exemple, chaque patte inférieure peut être solidaire d'une pièce venant se loger dans une encoche d'une autre pièce solidaire du doigt 4 et, ce, lorsque les pattes sont en position verrouillée. En utilisation, la rétraction du doigt 4 permet la libération de la pièce solidaire de la patte inférieure et entraîne dès lors son déplacement vers l'extérieur sous l'effet du poids de la munition. Le mouvement de la patte supérieure est quant à lui lié à celui de la patte inférieure, par exemple, via un engrenage (non représenté). En position déverrouillée, les pattes sont ainsi libres de se déplacer radialement, l'amplitude de l'écartement étant fonction du type de munition.The gripping device according to the invention comprises a mechanism for unlocking the tabs actuated by contact with retractable fingers, said unlocking, with an external element. According to the invention, the retractable fingers 4 are positioned on the front face of the support ( fig.1 ). In use, this face abuts against the breech of the barrel, which, via the retraction of the fingers inside of the support, triggers the joint opening of the legs and allows the ammunition to enter the barrel chamber. According to the embodiment of the figure 1 , the fingers 4 to the left and to the right triggers respectively and independently the radial opening of the tabs to the left and right. Different systems can be envisaged to link the retraction of the fingers 4 to the radial expansion of the tabs. For example, each lower leg may be secured to a piece which is housed in a notch of another part secured to the finger 4 and, when the tabs are in the locked position. In use, the retraction of the finger 4 allows the release of the integral part of the lower leg and therefore causes its outward displacement under the effect of the weight of the ammunition. The movement of the upper leg is linked to that of the lower leg, for example, via a gear (not shown). In the unlocked position, the tabs are thus free to move radially, the amplitude of the spacing being a function of the type of ammunition.

Le dispositif de préhension comporte en outre un mécanisme de rappel permettant le retour du support devant la position de chargement du magasin après le transport de la munition dans la chambre du canon. Le mécanisme comporte un verrou 12 visible à la figure 4. Le verrou 12 est monté pivotant sur le support 1 et muni d'une butée 13. Le mécanisme de rappel comporte en outre un doigt de rappel 5, positionné sur la face avant du support (fig.1) et un ressort de rappel (non représenté). En utilisation et comme explicité ci-dessous, la rétraction au sein du support du doigt de rappel 5 déclenche l'escamotage du verrou et dès lors le retour du support sous l'effet du ressort de rappel. A titre d'exemple, la liaison entre le doigt de rappel et le verrou peut être assurée via une tige (non représentée). Pour permettre le déverrouillage des pattes avant le retour du support, la longueur du doigt de rappel est inférieure à celle des doigts de déverrouillage.The gripping device further comprises a return mechanism for returning the support to the loading position of the magazine after the transport of the munition in the chamber of the barrel. The mechanism includes a latch 12 visible to the figure 4 . The latch 12 is pivotally mounted on the support 1 and provided with a stop 13. The return mechanism further comprises a return finger 5, positioned on the front face of the support ( fig.1 ) and a return spring (not shown). In use and as explained below, the retraction within the support of the return finger 5 triggers the retraction of the lock and therefore the return of the support under the effect of the return spring. For example, the connection between the return finger and the latch can be provided via a rod (not shown). To allow the unlocking of the legs before the return of the support, the length of the return finger is less than that of the unlocking fingers.

Le support 1 vu dans son entièreté à la figure 4 présente une forme proche d'un L couché. Les pattes 2 sont disposées sur la portion verticale du L couché, c'est-à-dire la portion de petite dimension du L, tandis que la partie horizontale du L est destinée à se positionner le long du fourreau 6 comportant la munition 3 dans le magasin.The support 1 seen in its entirety at the figure 4 has a shape close to a lying L. The tabs 2 are arranged on the vertical portion of the L lying, that is to say the small portion of the L, while the horizontal portion of the L is intended to be positioned along the sleeve 6 comprising the ammunition 3 in the shop.

Le mécanisme d'entrainement du support 1 comporte une partie fixe 7 munie d'un moteur, un bâti poussoir 10 monté coulissant sur cette partie fixe 7 et un chariot 9 lui-même monté coulissant sur le bâti poussoir 10 grâce, par exemple, à un système de chaine qui relie la partie fixe 7 au chariot 9 (non représenté). Le chariot 9 comporte un doigt poussoir 11 destiné à déplacer la munition 3 depuis le magasin 6 jusqu'à la chambre du canon 8. Le déplacement du support 1 s'effectue, d'une part, indirectement via le déplacement de la munition 3 qui est serrée dans les pattes 2 du support et poussée au niveau de son culot par le doigt poussoir 11, et, d'autre part, via le chariot 9 qui exerce une pression sur la butée 13 du verrou 12 solidaire du support 1.The drive mechanism of the support 1 comprises a fixed part 7 provided with a motor, a push frame 10 slidably mounted on this fixed part 7 and a carriage 9 itself slidably mounted on the push frame 10 by, for example, a chain system which connects the fixed part 7 to the carriage 9 (not shown). The carriage 9 comprises a pusher finger 11 intended to move the munition 3 from the magazine 6 to the chamber of the barrel 8. The displacement of the support 1 is effected, on the one hand, indirectly via the movement of the ammunition 3 which is clamped in the legs 2 of the support and pushed at its base by the pusher finger 11, and, secondly, via the carriage 9 which exerts pressure on the abutment 13 of the latch 12 secured to the support 1.

Le fonctionnement du dispositif selon l'invention est schématiquement représenté à la figure 5. Le support 1 est positionné à un endroit donné devant un des fourreaux 6 du magasin, appelé position de chargement. Lorsqu'une munition 3 doit être chargée, le fourreau 6 comprenant la munition 3 à charger est grâce à un convoyeur (non représenté) placé dans la position de chargement (fig.5(a)). Ensuite, le bâti poussoir 10 sur lequel est monté le chariot 9 muni du doigt 11 entre en action (fig.5(b)). Le doigt poussoir 11 exerce une pression sur le culot de la munition 3 afin de l'insérer dans l'espace délimité par les pattes 2 qui, par défaut, sont en position verrouillée. De par sa forme légèrement conique (non représentée sur la figure schématique 5) et l'écartement donné des pattes, la munition se bloque dans ces dernières lorsque les pattes couvrent la partie de la douille où se trouve le centre de gravité de la munition. En parallèle, le chariot 9 vient buter contre le verrou 12 et, plus précisément, sa butée 13 (fig.5(c)). L'action conjointe du doigt poussoir 11 sur la munition 3 serrée dans le support de préhension 1 et du chariot 9 sur le verrou 12 engendre dès lors le déplacement du support 1. En fin de course, comme montré à la figure 5(d), le support 1 bute contre la culasse du canon 8 ce qui déclenche dans un premier temps l'écartement radial des pattes via la rétraction des doigts de déverrouillage comme mentionné précédemment et permet le chargement de la munition 3 dans la chambre du canon 8 grâce au doigt poussoir 11 toujours en mouvement (fig.5(d)). Dans un deuxième temps, le contact du doigt de rappel avec la culasse du canon assure le retour du support 1 dans la position de chargement grâce à l'escamotage du verrou 12 et au ressort de rappel (fig.5(d) et (e)). Ensuite, le chariot 9 revient dans sa position de départ de la figure 5(a) sous l'action du moteur. On précisera qu'en cas de défectuosité du ressort qui empêcherait le retour du support dans sa position de chargement, le retour du support peut être assuré via le chariot. Le verrou est alors escamoté et le chariot prend position sur la partie arrière du support afin de l'entraîner dans son mouvement.The operation of the device according to the invention is schematically represented at the figure 5 . The support 1 is positioned at a given location in front of one of the sleeves 6 of the store, called the loading position. When a munition 3 must be loaded, the sheath 6 comprising the munition 3 to be loaded is through a conveyor (not shown) placed in the loading position ( Fig.5 (a) ). Then, the push frame 10 on which is mounted the carriage 9 provided with the finger 11 comes into action ( Fig.5 (b) ). Finger pusher 11 exerts pressure on the base of the ammunition 3 to insert it in the space defined by the legs 2 which, by default, are in the locked position. Due to its slightly conical shape (not shown in the schematic figure 5) and the given spacing of the legs, the ammunition is blocked in the latter when the tabs cover the portion of the sleeve where the center of gravity of the ammunition. In parallel, the carriage 9 abuts against the latch 12 and, more precisely, its stop 13 ( Fig.5 (c) ). The joint action of the pusher finger 11 on the munition 3 clamped in the gripping support 1 and the carriage 9 on the latch 12 therefore causes the displacement of the support 1. At the end of the race, as shown in FIG. Figure 5 (d) , the support 1 abuts against the breech of the barrel 8 which triggers at first the radial spacing of the tabs via the retraction of the unlocking fingers as mentioned above and allows the loading of the ammunition 3 in the chamber of the barrel 8 thanks to the push finger 11 still moving ( Fig.5 (d) ). In a second step, the contact of the return finger with the breech of the barrel ensures the return of the support 1 in the loading position by retracting the latch 12 and the return spring ( fig.5 (d) and (e) ). Then, the carriage 9 returns to its starting position of the Figure 5 (a) under the action of the engine. It will be specified that in case of defective spring which would prevent the return of the support in its loading position, the return of the support can be provided via the carriage. The lock is then retracted and the carriage takes position on the rear part of the support in order to drag it in its movement.

Grâce au dispositif de préhension selon l'invention, le support accompagne donc la munition depuis le magasin jusqu'à la chambre du canon selon un mouvement longitudinal, empêchant tout basculement de cette dernière grâce aux pattes.With the gripping device according to the invention, the support therefore accompanies the ammunition from the store to the barrel chamber in a movement longitudinal, preventing any tilting of the latter through the legs.
