Description

L'invention a pour objet un tourelleau support d'arme pour un véhicule blindé.The subject of the invention is a weapon support cupola for an armored vehicle.

Un véhicule blindé est armé généralement d'un tourelleau constitué d'une carapace blindée montée rotative autour d'un axe vertical et sur laquelle est articulée, autour d'un axe horizontal, une partie oscillante supportant une arme qui peut être un canon ou bien un ou plusieurs caissons lance-engins.An armored vehicle is generally armed with a cupola consisting of an armored shell rotatably mounted around a vertical axis and on which is articulated, around a horizontal axis, an oscillating part supporting a weapon which can be a gun or else one or more vehicle launchers.

Le véhicule est muni de moyens d'orientation du tourelleau autour de son axe vertical pour le pointage en azimut et de la partie oscillante autour de son axe horizontal pour le pointage en site. D'autre part, la partie oscillante peut avantageusement être munie des moyens optiques de pointage.The vehicle is provided with means for orienting the cupola around its vertical axis for pointing in azimuth and the oscillating part around its horizontal axis for pointing in elevation. On the other hand, the oscillating part can advantageously be provided with optical pointing means.

Généralement, on place sur le tourelleau deux caissons lance- engins de part et d'autre du plan médian et on est obligé de les écarter de la carapace pour permettre leur orientation en site. Ils sont ainsi assez vulnérables et augmentent l'encombrement du véhicule.Generally, two machine-launching boxes are placed on the cupola on either side of the median plane and it is necessary to separate them from the shell to allow their orientation in elevation. They are thus quite vulnerable and increase the size of the vehicle.

Il est possible, d'autre part, d'associer des caissons extérieurs à une arme placée à l'intérieur de la tourelle. Cependant, jusqu'à présent, on devait munir les caissons d'une optique de visée indépendante de celle du canon.It is possible, on the other hand, to associate external casings with a weapon placed inside the turret. However, until now, we had to equip the boxes with an optical sight independent of that of the gun.

L'invention a pour objet un nouveau mode de montage du support d'arme permettant de remédier à ces inconvénients.The subject of the invention is a new method of mounting the weapon support which makes it possible to remedy these drawbacks.

Conformément à l'invention, la partie oscillante comprend, sur au moins un côté de la carapace, une pièce de support formant pivot, montée rotative sur la carapace autour de l'axe horizontal et reliée cinématiquement aux moyens d'orientation en site, un support d'arme comprenant un caisson fixé à l'extrémité d'un bras monté articulé sur le pivot autour d'un axe horizontal placé au-dessus de l'axe d'orientation en site et dirigé perpendiculairement à celui-ci et un moyen de basculement du bras de support d'arme autour de son axe d'articulation sur le pivot entre une position basse de repos pour laquelle l'arme est plaquée contre la carapace et une position haute de tir pour laquelle l'arme est écartée de la carapace et libre de tourner avec le pivot sous l'action des moyens d'orientation de la partie oscillante.According to the invention, the oscillating part comprises, on at least one side of the shell, a support piece forming a pivot, rotatably mounted on the shell around the horizontal axis and kinematically connected to the elevation orientation means, a weapon support comprising a box fixed to the end of an arm mounted articulated on the pivot about a horizontal axis placed above the axis of orientation in elevation and directed perpendicular thereto and a means tilting of the weapon support arm around its axis of articulation on the pivot between a low rest position for which the weapon is pressed against the shell and a high firing position for which the weapon is moved away from the shell and free to rotate with the pivot under the action of the means of orientation of the oscillating part.

De préférence, le pivot comprend une pièce cylindrique montée rotative dans des paliers portés par la carapace et centrés sur l'axe d'orientation en site, s'étendant en porte à faux vers l'extérieur de la carapace et sur laquelle sont fixés deux montants parallèles s'étendant vers le haut et portant des paliers de guidage en rotation d'un axe horizontal perpendiculaire à la direction de l'axe d'orientation en site et sur lequel est articulé le bras de support d'arme.Preferably, the pivot comprises a cylindrical part rotatably mounted in bearings carried by the shell and centered on the axis of orientation in elevation, extending cantilevered towards the outside of the shell and on which are fixed two parallel uprights extending upward and bearing bearings for guiding in rotation a horizontal axis perpendicular to the direction of the elevation orientation axis and on which the support arm d is articulated 'armed.

Selon une autre caractéristique, le moyen de basculement du bras est constitué par un vérin hydraulique s'étendant entre les deux montants du pivot et dont le corps est articulé sur le pivot et la tige sur le bras de support d'arme, en un point écarté de l'axe horizontal de rotation du bras.According to another characteristic, the arm tilting means is constituted by a hydraulic cylinder extending between the two uprights of the pivot and whose body is articulated on the pivot and the rod on the weapon support arm, at a point away from the horizontal axis of rotation of the arm.

Selon une autre caractéristique importante, l'un au moins des montants de support de l'axe de rotation est prolongé au-delà de ce dernier et porte à son extrémité un moyen de verrouillage du bras en position haute. Ce moyen de verrouillage comprend au moins un verrou comportant un pêne mobile parallèlement à l'axe de basculement et sollicité du côté du bras par un moyen élastique, un orifice formant gâche ménagé sur le bras à la même distance que le pêne de l'axe de basculement de façon à coincider avec le pêne en position haute du bras, l'orifice étant précédé, dans le sens de montée du bras, d'une rampe d'écartement du pêne pour l'engagement de celui-ci dans l'orifice lorsque le bras arrive en position haute.According to another important characteristic, at least one of the support uprights of the axis of rotation is extended beyond the latter and carries at its end means for locking the arm in the high position. This locking means comprises at least one latch comprising a bolt movable parallel to the tilting axis and urged on the side of the arm by an elastic means, an opening forming a strike formed on the arm at the same distance as the bolt from the axis. tilting so as to coincide with the bolt in the upper position of the arm, the orifice being preceded, in the direction of raising of the arm, by a ramp for spacing the bolt for the engagement of the latter in the orifice when the arm reaches the high position.

There is shown in the accompanying figures a particular embodiment of the invention, given by way of non-limiting example.
  • Figure 1 is a schematic front view of an armored vehicle provided with improvements according to the invention.
  • Figure 2 is an enlarged front view of the weapon support arm.
  • FIG. 3 is a side view along arrow A in FIG. 2.
  • Figure 4 is an axial sectional view of the weapon support in the low position.
  • Figure 5 is a sectional view along AA of Figure 4 of the locking device.

Sur la figure 1, on a représenté schématiquement, en vue de face, un tourelleau 1 monté sur la partie supérieure de la caisse 11 d'un véhicule blindé muni de moyens d'orientation non représentés du tourelleau 1 autour de son axe vertical 10.In FIG. 1, there is shown diagrammatically, in front view, a cupola 1 mounted on the upper part of the body 11 of an armored vehicle provided with orientation means, not shown, of the cupola 1 around its vertical axis 10.

La partie oscillante, non représentée en détail et qui peut comporter par exemple un canon, est montée articulée sur le tourelleau autour d'un axe horizontal 12, le tourelleau étant muni de moyens mécaniques ou hydrauliques, non réprésentés, d'orientation de la partie oscillante autour de l'axe 12 pour le pointage en site.The oscillating part, not shown in detail and which may comprise for example a barrel, is mounted articulated on the cupola around a horizontal axis 12, the cupola being provided with mechanical means or hydraulic, not shown, orienting the oscillating part around axis 12 for pointing in elevation.

Sur les deux côtés du tourelleau, de part et d'autre du plan médian P, sont placés deux pivots 2 centrés chacun sur l'axe horizontal 12. L'un de ces pivots est représenté plus en détails et en coupe axiale sur la figure 4.On both sides of the cupola, on either side of the median plane P, are placed two pivots 2 each centered on the horizontal axis 12. One of these pivots is shown in more detail and in axial section in the figure. 4.

Le pivot 2 est constitué par une pièce cylindrique centrée dans un boitier 13 solidaire de la carapace du tourelleau 1, par l'intermédiaire de paliers 14. la pièce cylindrique 2 s'étend en porte-à-faux vers l'extérieur et est solidaire de la partie oscillante du tourelleau dont on s'est borné à représenter schématiquement, sur la figure, le masque 15 de fermeture de l'orifice de passage du canon et l'axe des tourillons 16 en bout duquel est fixée la pièce cylindrique 2.The pivot 2 is constituted by a cylindrical piece centered in a box 13 secured to the shell of the cupola 1, by means of bearings 14. the cylindrical piece 2 extends in cantilever towards the outside and is secured of the oscillating part of the cupola, which we have limited to schematically representing, in the figure, the mask 15 for closing the barrel passage orifice and the axis of the trunnions 16 at the end of which is fixed the cylindrical part 2.

Comme on le voit sur la figure 3, la pièce cylindrique 2 porte deux bras parallèles 21 constitués de tôles fixées tangentiellement sur les deux côtés de la pièce cylindrique 2 et s'étendant vers le haut en suivant sensiblement le profil de la carapace 1.As can be seen in FIG. 3, the cylindrical part 2 carries two parallel arms 21 made up of sheets fixed tangentially on the two sides of the cylindrical part 2 and extending upwards substantially following the profile of the shell 1.

De façon classique, les engins sont placés à l'intérieur d'un caisson 3 et celui-ci est fixé, selon l'invention, à l'extrémité d'un bras de support 31 comprenant deux parties encadrant les deux montants 21 et articulées sur ceux-ci autour de deux pivots 32 centrés sur un axe d'articulation 30 placé au-dessus de l'axe d'orientation en site 12 et dirigé perpendiculairement à celui-ci.Conventionally, the machines are placed inside a box 3 and this is fixed, according to the invention, to the end of a support arm 31 comprising two parts framing the two uprights 21 and articulated on these around two pivots 32 centered on a hinge axis 30 placed above the elevation orientation axis 12 and directed perpendicular thereto.

Le bras 31 de support d'arme est muni, en outre, dans sa partie centrale, d'une chape 37 portant un axe 33 parallèle à l'axe d'articulation 30 et sur lequel vient s'articuler la tige 41 d'un vérin 4 dont le corps 42 est articulé à sa base sur un support 22 placé à la partie inférieure de la pièce cylindrique 2 à l'intérieur et dans le plan médian de celle-ci, le vérin 4 passant dans une ouverture allongée 23 ménagée à la partie supérieure de la pièce 2.The arm 31 of the weapon support is further provided, in its central part, with a yoke 37 carrying an axis 33 parallel to the articulation axis 30 and on which the rod 41 of a cylinder 4 whose body 42 is articulated at its base on a support 22 placed at the lower part of the cylindrical part 2 inside and in the median plane thereof, the cylinder 4 passing through an elongated opening 23 formed at the upper part of room 2.

Le vérin 4, qui est relié à des moyens de commande hydraulique non représentés, commande le basculement du bras de support 3 autour de son axe d'articulation 30 entre une position basse représentée sur la figure 4, pour laquelle le vérin est replié et une position haute représentée sur la figure 2 et 3 pour laquelle le vérin est déplié.The jack 4, which is connected to hydraulic control means (not shown), controls the tilting of the support arm 3 around its articulation axis 30 between a low position shown in FIG. 4, for which the jack is folded and a high position shown in Figure 2 and 3 for which the cylinder is unfolded.

Dans la position basse, le caisson 3, vient s'encastrer à la partie inférieure du tourelleau, comme on l'a représenté sur la figure 4. Cependant, dans la position haute, il est nécessaire de bloquer le bras de support 3 pour permettre un pointage précis. A cet effet, on utilise un moyen de verrouillage représenté schématiquement sur les figures 4 et 5.In the low position, the casing 3 is fitted into the lower part of the cupola, as shown in FIG. 4. However, in the high position, it is necessary to block the arm of support 3 to allow precise pointing. For this purpose, use is made of a locking means shown diagrammatically in FIGS. 4 and 5.

Les deux montants parallèles 21 sont prolongés vers le haut au-dessus de l'axe d'articulation 30 et sont reliés à leur extrémité supérieure 24 par un tube 23 à l'intérieur duquel est monté le dispositif de verrouillage 5. Comme on l'a représenté sur la figure 5, ce dernier est constitué de deux verrous comportant chacun un pêne 51 ménagé à l'extrémité d'une pièce cylindrique 52 montée coulissante à l'intérieur du tube 23. Celui-ci contient un ressort 53 qui repousse vers l'extérieur les deux pièces cylindriques 52, dans des directions opposées.The two parallel uprights 21 are extended upwards above the hinge pin 30 and are connected at their upper end 24 by a tube 23 inside which is mounted the locking device 5. As is shown in Figure 5, the latter consists of two locks each comprising a bolt 51 formed at the end of a cylindrical piece 52 slidably mounted inside the tube 23. The latter contains a spring 53 which pushes towards outside the two cylindrical parts 52, in opposite directions.

Le bras de support d'arme 31 est muni lui-même de deux oreilles 34 portant des orifices 35 qui sont centrés à la même distance de l'axe d'articulation 30 que le tube 23 et les deux pistons 52. De la sorte, comme on l'a représenté sur la figure 5, lorsque le vérin 4 redresse le bras de support 31, les deux oreilles 34 encadrent les extrémités supérieures 22 des deux montants parallèles et les orifices 35 viennent se centrer sur l'axe 50 des deux pistons 52. A la hauteur des deux orifices 35, les oreilles 34 portent avantageusement une partie chanfreinée 36 formant une rampe susceptible, lorsque le bras 31 arrive en position haute, d'écarter les pênes 51 contre l'action du ressort 53, en coopérant éventuellement avec des faces inclinées ménagées sur les pênes 51. Ces dernier peuvent ainsi s'engager dans les orifices 35 qui forment donc les gâches des deux verrous.The weapon support arm 31 is itself provided with two ears 34 carrying orifices 35 which are centered at the same distance from the articulation axis 30 as the tube 23 and the two pistons 52. In this way, as shown in FIG. 5, when the jack 4 straightens the support arm 31, the two ears 34 frame the upper ends 22 of the two parallel uprights and the orifices 35 are centered on the axis 50 of the two pistons 52. At the height of the two orifices 35, the ears 34 advantageously carry a chamfered part 36 forming a ramp capable, when the arm 31 reaches the high position, of spreading the bolts 51 against the action of the spring 53, possibly cooperating with inclined faces formed on the bolts 51. The latter can thus engage in the orifices 35 which therefore form the keepers of the two latches.

Pour ouvrir les verrous et permettre l'abaissement du bras 31, on peut par exemple utiliser un système de déverrouillage tel que celui qui a été représenté sur la figure 5 et qui comprend, pour chaque verrou, un levier coudé 54 articulé autour d'un axe 55 perpendiculaire à l'axe 50 du verrou et dont une extrémité s'engage dans une gorge 56 du piston 52 alors que l'autre extrémité est reliée à un système 57 de commande par table. En commandant la rotation du levier au moyen du système 57, on écarte les deux verrous qui se dégagent des gâches 35 pour permettre l'abaissement du bras 31, puis reviennent dans leur position écartée de verrouillage.To open the locks and allow the lowering of the arm 31, one can for example use an unlocking system such as that which has been shown in FIG. 5 and which comprises, for each lock, an elbow lever 54 articulated around a axis 55 perpendicular to the axis 50 of the bolt and one end of which engages in a groove 56 of the piston 52 while the other end is connected to a table control system 57. By controlling the rotation of the lever by means of the system 57, the two latches which are released from the keepers 35 are removed to allow the lowering of the arm 31, then return to their separated locking position.

Le bras 31 et par conséquent le caisson lance-engin 3 peut ainsi être bloqué dans la position haute représentée sur les figures 1 et 2 par rapport aux montants 21 solidaires du pivot 2. Comme celui-ci est lui-même solidaire de l'axe des tourillons 16, les moyens d'orientation en site schématisés sur la figure par une commande cinématique 17 commandent le pointage en site du caisson en même temps que celui de toute la partie oscillante. En effet, en position haute, le caisson est bien dégagé de la carapace 1 du tourelleau et peut donc être orienté librement. En revanche, dans la position basse représentée sur la figure 4 et en traits mixtes sur la figure 1, les deux caissons lance--engins viennent s'inclure dans le gabarit du véhicule dont on réduit ainsi l'encombrement, les armes étant en outre moins vulnérables.The arm 31 and consequently the machine-launching box 3 can thus be locked in the high position shown in FIGS. 1 and 2 with respect to the uprights 21 secured to the pivot 2. As the latter is itself secured to the axis pins 16, the elevation orientation means shown diagrammatically in the figure by a kinematic control 17 control the elevation pointing of the box at the same time as that of the entire oscillating part you. In fact, in the high position, the box is well released from the shell 1 of the cupola and can therefore be oriented freely. On the other hand, in the low position shown in FIG. 4 and in dashed lines in FIG. 1, the two launchers boxes are included in the size of the vehicle, the bulk of which is thus reduced, the arms being furthermore less vulnerable.

On remarquera également que, en position haute, le caisson 3 peut être facilement ouvert pour permettre le chargement.It will also be noted that, in the high position, the box 3 can be easily opened to allow loading.

Bien entendu, les dispositions particulières représentées sur les figures n'ont été données qu'à titre d'exemple et pourraient être remplacées par des moyens équivalents assurant les mêmes fonctions. C'est ainsi notamment, que l'on pourrait imaginer bien d'autres modes de fixation et de commande du bras de support d'arme sur le pivot, celui-ci pouvant également prendre d'autres formes.Of course, the particular provisions shown in the figures have been given only by way of example and could be replaced by equivalent means ensuring the same functions. Thus, in particular, one could imagine many other methods of fixing and controlling the weapon support arm on the pivot, the latter also being able to take other forms.

D'autre part, on notera que le dispositif selon l'invention peut remplacer l'arme, par exemple un canon, placée à'l'intérieur de la tourelle ou lui être simplement associé, la fixation du pivot sur l'axe des tourillons pouvant se faire sans modification des dispositions existantes. Dans ce cas, l'optique de visée solidaire de la masse oscillante peut être commune au canon et aux engins.On the other hand, it is noted that the device according to the invention can replace the weapon, for example a cannon placed 'inside the turret or it simply be associated, the fixing of the pivot on the trunnion axis can be done without modification of existing provisions. In this case, the sighting optic integral with the oscillating mass can be common to the barrel and to the vehicles.
