Description

Le domaine technique de la présente invention est celui des moyens de fixation d'un frein de bouche sur le tube d'une arme à feu de moyen ou de gros calibre.The technical field of the present invention is that of the means for fixing a muzzle brake on the barrel of a medium or large caliber firearm.

Pour réduire les efforts résultant de l'action des gaz de combustion de la charge propulsive d'une munition sur une arme, il est bien connu d'adjoindre à l'extrémité libre du tube de l'arme un frein de bouche qui crée un effort contraire à celui engendré par les gaz. Les freins de bouche utilisés dans le monde, en particulier sur les artilleries de gros calibre, ont une masse relativement importante néfaste à l'équilibrage de l'arme. La fixation de tels freins de bouche est réalisée le plus souvent par un filetage auquel on adjoint plusieurs composants tels un contre-écrou, une rondelle de freinage, une clavette, etc... .Ces composants ont une masse non négligeable et un coût. De plus, la résistance du tube est diminuée par la présence d'une rainure pour loger la clavette, surtout si elle est débouchante à l'avant du tube et les usinages spécifiques sur le tube et le frein augmentent encore le coût de ces solutions.To reduce the efforts resulting from the action of propellant charge combustion gas from a ammunition on a weapon, it is well known to add to the free end of the barrel a muzzle brake which creates an effort contrary to that generated by gas. The muzzle brakes used worldwide, in especially on large caliber artillery, have a relatively large mass harmful to balancing the weapon. The fixing of such brakes mouth is most often produced by threading to which we add several components such as a lock nut, a lock washer, a key, etc ... components have a significant mass and a cost. Of more, the resistance of the tube is decreased by the presence of a groove to accommodate the key, especially if it opens out at the front of the tube and specific machining on the tube and the brake increases still the cost of these solutions.

Ainsi, le brevet FR-A-2 718 839 décrit un frein de bouche entourant complètement l'extrémité libre du tube de l'arme. Ce frein de bouche est fixé au tube par un filetage, un écrou d'arrêt permettant de fixer leur position axiale respective. Une clavette fixée par des vis assure le blocage en rotation du frein de bouche par rapport au tube.Thus, patent FR-A-2,718,839 describes a brake mouth completely surrounding the free end of the tube of the weapon. This muzzle brake is fixed to the tube by a thread, a stop nut for fixing their respective axial position. A key fixed by screw secures the muzzle brake in rotation relative to the tube.

Les brevets CH-A-240 479 et FR-A-715 769 décrivent un frein de bouche vissé sur l'extrémité avant du tube d'une arme. Ce frein prolonge le tube et prend appui sur la face avant du tube. Aucun moyen d'arrêt n'est décrit dans ces documents.The patents CH-A-240 479 and FR-A-715 769 describe a muzzle brake screwed onto the front end of the tube of a weapon. This brake extends the tube and takes support on the front of the tube. No means of stopping is described in these documents.

Le but de la présente invention est de fournir un dispositif de fixation d'un frein de bouche sur le tube d'une arme permettant de réduire le nombre d'éléments assurant cette fixation.The object of the present invention is to provide a device for fixing a muzzle brake on the tube a weapon to reduce the number of elements ensuring this fixation.

L'invention a donc pour objet un dispositif de fixation d'un frein de bouche sur le tube d'une arme à l'aide d'une liaison filetée, le frein de bouche comportant une paroi d'appui coopérant avec la face avant du tube, caractérisé en ce que le tube comporte une portée avant cylindrique disposée en avant du filetage coopérant avec une portée correspondante du frein assurant le centrage du frein, et en ce qu'il comporte au moins un moyen d'arrêt en rotation du frein interposé entre le frein de bouche et le tube.The invention therefore relates to a device for fixing a muzzle brake on the barrel of a handgun using a threaded connection, the muzzle brake comprising a bearing wall cooperating with the face front of the tube, characterized in that the tube has a cylindrical front bearing disposed in front of the thread cooperating with a corresponding span of the brake ensuring the centering of the brake, and in that it includes at least one brake stop means interposed between the muzzle brake and the tube.

Selon une caractéristique de l'invention, le tube comporte une portée arrière coopérant avec une portée correspondante du frein, cette portée arrière étant située à l'opposé de la portée avant par rapport au filetage.According to a characteristic of the invention, the tube has a rear reach cooperating with a reach corresponding to the brake, this rear range being located opposite the front span relative to the thread.

Selon une autre caractéristique, le moyen d'arrêt est situé au niveau d'une portée de centrage et il est constitué d'au moins une vis de pression disposée transversalement entre le frein de bouche et le tube.According to another characteristic, the stop means is located at a centering span and is consisting of at least one pressure screw arranged transversely between the muzzle brake and the tube.

La vis est en appui sur un méplat pratiqué dans l'épaisseur du tube et présente un moyen d'arrêt en rotation pouvant être un contre-écrou.The screw is supported on a flat formed in the thickness of the tube and has a stop means in rotation can be a lock nut.

Avantageusement, la vis de pression et le méplat sont positionnés de telle sorte que son serrage précontraint la liaison filetée en engendrant un couple de serrage supplémentaire du frein de bouche sur le tube.Advantageously, the pressure screw and the flat are positioned so that its tightening preloads the threaded connection by generating torque additional clamping of the muzzle brake on the tube.

Selon une autre caractéristique de l'invention, l'axe de la vis de pression est parallèle à un diamètre du tube et perpendiculaire au méplat et est situé à une distance D de l'axe du tube de l'ordre de 0,3 à 0,7 fois le rayon extérieur de ce tube.According to another characteristic of the invention, the axis of the pressure screw is parallel to a diameter of the tube and perpendicular to the flat and is located at a distance D from the axis of the tube of the order of 0.3 to 0.7 times the outside radius of this tube.

Préférentiellement, deux vis de pression sont disposées symétriquement par rapport à l'axe du tube. Preferably, two pressure screws are arranged symmetrically with respect to the axis of the tube.

Selon une variante de réalisation, le dispositif de fixation d'un frein de bouche comporte une cale disposée entre la face avant du tube et la paroi du frein de bouche.According to an alternative embodiment, the device muzzle brake attachment has a shim disposed between the front face of the tube and the wall of the muzzle brake.

L'avantage du dispositif de fixation d'un frein de bouche selon l'invention réside dans sa simplicité qui permet de réduire sa masse globale.The advantage of the fixing device of a brake mouth according to the invention lies in its simplicity which reduces its overall mass.

D'autres caractéristiques, détails et avantages de l'invention ressortiront plus clairement à la lecture du complément de description donné ci-après à titre indicatif en relation avec des dessins dans lesquels :

  • la figure 1 est une demi-coupe longitudinale du tube et du frein de bouche selon l'invention,
  • la figure 2 est une coupe transversale du tube et du frein de bouche pratiquée au niveau des vis d'arrêt, selon le plan AA de la figure 1,
  • la figure 3 est une demi-coupe montrant une variante de réalisation du dispositif de fixation selon l'invention.
Other characteristics, details and advantages of the invention will emerge more clearly on reading the additional description given below for information only in relation to the drawings in which:
  • FIG. 1 is a longitudinal half-section of the tube and of the muzzle brake according to the invention,
  • FIG. 2 is a cross section of the tube and the muzzle brake made at the level of the stop screws, according to the plane AA of FIG. 1,
  • Figure 3 is a half-section showing an alternative embodiment of the fixing device according to the invention.

Sur la figure 1, on a représenté un dispositif de fixation 1 suivant une demi-coupe pratiquée selon l'axe 2 du tube 3 d'une arme non représentée. L'extrémité 4 du tube 2 reçoit un frein de bouche 5 comportant classiquement des aubes 6 destinées au passage des gaz de combustion de la charge propulsive. L'extrémité 4 du tube 10 comprend une portée avant 7 cylindrique et un filetage 9. La face avant 10 du tube est sensiblement perpendiculaire à l'axe 2. Le frein de bouche 5 comporte une partie tubulaire allongée 11 destinée à s'engager autour de l'extrémité 4 du tube. Cette partie 11 comporte un taraudage 13 coopérant avec le filetage 9 et une portée avant 14 coopérant avec la portée 7 du tube afin d'assurer un centrage. Le frein comporte également une paroi interne transversale 15 destinée à venir en contact avec la face avant 10 du tube. Lorsque la paroi 15 est en appui sur la face 10 du tube, on voit sur la figure que le frein de bouche est complètement vissé. De cette manière, aucun jeu ne subsiste entre la face avant 10 du tube et la paroi 15. On interdit ainsi tout passage dans le filetage, des gaz de propulsion engendrés par la charge propulsive Le frein de bouche, selon l'invention, a donc une étanchéité améliorée par rapport aux freins de bouche connus.In Figure 1, there is shown a device for attachment 1 along a half-cut made along the axis 2 of the tube 3 of a weapon not shown. The end 4 of the tube 2 receives a muzzle brake 5 comprising conventionally vanes 6 intended for the passage of gases of propellant charge combustion. End 4 of tube 10 includes a cylindrical front seat 7 and a thread 9. The front face 10 of the tube is substantially perpendicular to the axis 2. The muzzle brake 5 comprises an elongated tubular part 11 intended for engage around the end 4 of the tube. This part 11 includes a thread 13 cooperating with the thread 9 and a front reach 14 cooperating with the reach 7 of the tube to ensure centering. The brake has also a transverse internal wall 15 intended for come into contact with the front face 10 of the tube. When the wall 15 bears on the face 10 of the tube, we see in the figure that the muzzle brake is completely screwed. In this way, no game remains between the front face 10 of the tube and the wall 15. This prevents any passage through the thread, propellant gases generated by the propellant charge Le muzzle brake according to the invention therefore has a improved seal compared to muzzle brakes known.

Les aubes 6 du frein de bouche 5 sont orientées de telle façon que les gaz de combustion de la charge propulsive d'une munition soient évacués latéralement, dans un plan horizontal par rapport au tube monté sur l'arme. Pour ce faire et de manière connue, le départ de filet du filetage 9 du tube est orienté par rapport à un usinage de positionnement du tube sur l'arme (non représenté), par exemple une rainure de clavette liant le manchon de culasse et le tube, et le départ de filet du taraudage 13 du frein de bouche est orienté par rapport aux aubes 6.The blades 6 of the muzzle brake 5 are oriented so that the charge gases from the charge propellant of an ammunition are evacuated laterally, in a horizontal plane with respect to the tube mounted on tear. To do this and in a known manner, the departure of thread of pipe thread 9 is oriented relative machining the tube on the weapon (not shown), for example a keyway binding the cylinder head sleeve and the tube, and the thread start of the muzzle brake thread 13 is oriented by compared to the vanes 6.

On a représenté des filetages 9 et 13 sous une forme dite trapézoïdale artillerie, mais on pourrait appliquer tout autre type de filetage.Threads 9 and 13 are shown under a so-called trapezoidal artillery form but we could apply any other type of thread.

Sur la figure 2, on a représenté une coupe transversale du tube 3 pratiquée au niveau des moyens d'arrêt en rotation du frein de bouche par rapport au tube. Ces moyens, qui sont situés au niveau des portées de centrage 7 et 14, sont constitués par deux vis 16 se vissant dans un taraudage 17 réalisé dans le frein et venant prendre appui sur un méplat 18 aménagé sur la partie extérieure du tube 3 et perpendiculaire à l'axe 25 du taraudage. Chaque vis 16 est arrêtée en rotation, par exemple, par un contre-écrou 19 qui vient se loger dans un lamage 27. Le positionnement de ces vis 16 est réalisé en fonction du sens du filet des filetages 9 et 13, de telle manière que le serrage des vis précontraint la liaison filetée en engendrant un couple de serrage supplémentaire du frein de bouche sur le tube.In Figure 2, there is shown a section transverse of the tube 3 practiced at the level of the means muzzle brake rotation stop relative to tube. These means, which are located at the ranges of centering 7 and 14, are constituted by two screws 16 se screwing into a thread 17 made in the brake and coming to rest on a flat 18 arranged on the outer part of tube 3 and perpendicular to the axis 25 of the thread. Each screw 16 is stopped in rotation, for example, by a lock nut 19 which is housed in a counterbore 27. The positioning of these screws 16 is made according to the direction of the thread of threads 9 and 13, so that the tightening of the screws preloads the threaded connection by generating torque additional clamping of the muzzle brake on the tube.

Dans l'exemple de réalisation représenté à la figure 2, les vis 16 se trouvent dans les secteurs angulaires S et S' délimités par deux diamètres perpendiculaires 21 et 22 du tube. L'axe 25 et 26 de chacune des vis étant parallèle à un diamètre 21 du tube, un serrage des vis tend à faire tourner le frein de bouche dans le sens horaire qui correspond à un filetage à droite.In the embodiment shown in Figure 2, the screws 16 are in the sectors angular S and S 'delimited by two diameters perpendiculars 21 and 22 of the tube. Axis 25 and 26 of each of the screws being parallel to a diameter 21 of the tube, tightening the screws tends to turn the brake mouth clockwise which corresponds to a right hand thread.

L'axe des vis est situé à une distance D de l'axe 28. De manière avantageuse, afin d'assurer un couple de blocage satisfaisant, tout en n'affaiblissant pas le tube au niveau de l'usinage du méplat 18, la distance D est de 0,3 à 0,7 fois le rayon extérieur 24 du tube 3.The axis of the screws is located at a distance D from the axis 28. Advantageously, in order to ensure a couple of satisfactory blocking, while not weakening the tube at the machining of the flat 18, the distance D is 0.3 to 0.7 times the outside radius 24 of the tube 3.

Sur cette figure, de manière optimum, deux moyens de blocage diamétralement opposés ont été représentés, mais un seul moyen de blocage pourrait suffir.In this figure, optimally, two means diametrically opposed locks have been shown, but only one blocking means could suffice.

Le taraudage 17 du frein et le méplat 18 dans l'épaisseur du tube sont usinés de telle façon qu'ils se retrouvent en vis-à-vis lorsque le frein de bouche est en position de blocage sur le tube de l'arme. Pour cela, le taraudage 17 et le méplat 18 sont orientés respectivement par rapport aux aubes 6 du frein de bouche et à l'usinage de positionnement du tube sur l'arme.The thread 17 of the brake and the flat 18 in the thickness of the tube are machined in such a way that they meet face to face when the muzzle brake is in the locked position on the barrel. For this, the thread 17 and the flat 18 are oriented respectively with respect to the vanes 6 of the brake mouth and tube positioning machining on tear.

Le montage du frein s'effectue de la façon suivante. On engage le frein autour de l'extrémité libre du tube 3 et on visse le frein jusqu'au contact intime entre la face avant 10 du tube et la paroi 15. Au fur et à mesure que le vissage progresse, les portées 7 et 14 respectives du tube et du frein viennent en contact. L'orientation des départs de filets permet d'assurer le bon positionnement du frein de bouche et de ses aubes 6, ainsi que des taraudages 17 et des méplats 18. On serre ensuite les vis 16 qui assurent un couple de serrage et de précontrainte du taraudage 13 sur le filetage 9, puis on bloque les contre-écrous 19. Les vis 16 font ainsi obstacle au dévissage du frein de bouche.The brake is assembled in the same way next. Apply the brake around the end free from tube 3 and screw the brake until contact intimate between the front face 10 of the tube and the wall 15. As the tightening progresses, the respective ranges 7 and 14 of the tube and the brake come in contact. The orientation of departures from threads ensure the correct positioning of the brake mouth and its blades 6, as well as threads 17 and flats 18. Then tighten the screws 16 which provide a tightening and prestressing torque for the thread 13 on thread 9, then block lock nuts 19. The screws 16 thus obstruct the unscrewing the muzzle brake.

Sur la figure 3, on a représenté une variante du dispositif de fixation d'un frein de bouche 5 sur le tube 3 d'une arme. Dans cette variante, un deuxième centrage du frein de bouche sur le tube est prévu. Ainsi le tube présente une deuxième portée 8 coopérant avec une portée 12 du frein de bouche, celles-ci étant situées en arrière de la liaison filetée 9, 13.In FIG. 3, a variant of the device for fixing a muzzle brake 5 to the tube 3 of a weapon. In this variant, a second the muzzle brake is centered on the tube. Thus the tube has a second bearing 8 cooperating with a range 12 of the muzzle brake, these being located behind the threaded connection 9, 13.

Sur cette figure, on a représenté le montage du frein de bouche 5 en interposant une cale 20 entre la face avant 10 du tube 3 et la paroi 15 du frein de bouche 5. Cette cale peut se présenter sous la forme d'une rondelle d'épaisseur variable, ajustée à la demande lors du montage du frein de bouche. Dans cette variante de réalisation, les départs de filets ne sont orientés par rapport à aucune référence, ce qui simplifie l'usinage du filetage 9 et du taraudage 13.In this figure, the assembly of the muzzle brake 5 by interposing a shim 20 between the front face 10 of the tube 3 and the wall 15 of the brake mouth 5. This wedge can be in the form a washer of variable thickness, adjusted to the request when installing the muzzle brake. In this variant, the thread starters are not oriented relative to any reference, which simplifies the machining of thread 9 and thread 13.

Le montage du frein de bouche s'effectue de la façon suivante. On engage le frein autour de l'extrémité libre du tube 3 et on visse le frein jusqu'au contact intime entre la face avant 10 du tube et la paroi 15. Généralement dans cette position les aubes 6 du frein de bouche sont mal orientées. Alors on dévisse le frein de bouche jusqu'à amener les aubes dans une position latérale correcte. On mesure ensuite l'espace dégagé entre la face avant 10 du tube et la paroi 15 du frein de bouche, puis on réalise une cale d'épaisseur correspondant à la mesure. On retire le frein de bouche afin de placer la cale 20 contre la paroi 15 du frein, puis on revisse le frein de bouche jusqu'en butée, ce qui amène les aubes 6 dans la bonne orientation. Enfin on serre les vis 16 et les contreécrous 19. The muzzle brake is assembled from the next way. We engage the brake around the free end of the tube 3 and we screw the brake up to the intimate contact between the front face 10 of the tube and the wall 15. Generally in this position the muzzle brake vanes 6 are incorrectly oriented. So we unscrews the muzzle brake until bringing the blades in a correct lateral position. We then measure the space cleared between the front face 10 of the tube and the wall 15 of the muzzle brake, then a block is produced of thickness corresponding to the measurement. We remove the muzzle brake in order to place the wedge 20 against the wall 15 of the brake, then screw the muzzle brake back on until the stop, which brings the blades 6 in the right orientation. Finally we tighten the screws 16 and the locknuts 19.

Dans cette variante de réalisation, les moyens d'arrêt en rotation du frein de bouche par rapport au tube peuvent être situés indifféremment au niveau des portées de centrage avant 7, 14 ou arrière 8,12.In this alternative embodiment, the means muzzle brake rotation stop relative to tube can be located indifferently at the level of centering spans front 7, 14 or rear 8.12.

Bien entendu, en variante, on pourrait ne réaliser qu'un seul centrage 7, 14 et dans le mode de réalisation représenté à la figure 1, deux portées pourraient également être envisagées.Of course, as a variant, one could not realize only one centering 7, 14 and in the mode of embodiment shown in Figure 1, two spans could also be considered.
