Description

Le domaine technique de la présente invention est celui des systèmes de guidage d'une masse reculante d'une artillerie par rapport à son berceau.The technical field of the present invention is that guidance systems for a receding mass of a artillery in relation to its cradle.

On sait que les artilleries sont animées d'un mouvement de recul et retour en batterie à chaque tir de munition par rapport au berceau sur lequel elles sont montées. Ce montage se retrouve dans une artillerie montée en tourelle ou dans une artillerie de campagne. La masse reculante est globalement constituée du canon prolongé par le manchon de culasse. Cette masse est montée coulissante par rapport au berceau et elle est freinée par exemple par des freins hydrauliques. Dans ce cas, le berceau est équipé de deux glissières et la masse reculante est solidaire d'un traíneau équipé de patins qui coulissent par rapport aux glissières. On connaít des systèmes dans lesquels la liaison traíneau/glissière est réalisée à l'aide d'un patin solidaire de la glissière par un pion et coulissant dans une rainure du traíneau. Dans cette configuration, le jeu latéral entre le traíneau et les deux glissières n'est pas maítrisé et de plus s'accroít avec l'usure.We know that artillery is animated by a movement of recoil and return to battery on each shot of ammunition by relative to the cradle on which they are mounted. This montage is found in an artillery mounted in a turret or in a field artillery. The receding mass is generally made up of the barrel extended by the sleeve of cylinder head. This mass is slidably mounted relative to the cradle and it is braked for example by brakes Hydraulic. In this case, the cradle is equipped with two slides and the receding mass is secured to a sled fitted with runners which slide in relation to the slides. We know systems in which the connection sled / slide is made using an integral shoe of the slide by a pin and sliding in a groove of the sled. In this configuration, the lateral clearance between the sled and the two slides is not under control and more increases with wear.

Le brevet CH-26013 (base pour le préambule de la revendicaion 1) décrit un système d'arme comprenant un tube monté coulissant sur une glissière incorporant un frein de recul. La glissière présente un profil rectangulaire qui reçoit une patte de forme complémentaire solidaire du tube. Dans cette réalisation, c'est le tube qui coulisse par rapport au patin qu'il surmonte et il n'est pas possible de prévoir un réglage du jeu.Patent CH-26013 (basis for the preamble of claim 1) describes a weapon system comprising a tube mounted sliding on a slide incorporating a brake step back. The slide has a rectangular profile which receives a tab of complementary shape integral with the tube. In this embodiment, it is the tube which slides by compared to the skate it overcomes and it is not possible to provide a clearance adjustment.

Le brevet GB-2 237 622 décrit un dispositif de guidage d'un tube d'arme permettant d'interdire le relèvement du tube lors du tir. Ce guidage comprend quatre rainures aménagées dans le tourillon et recevant des languettes solidaires du tube. Le tube est donc inséré dans le tourillon, ce qui interdit à priori toute possibilité de réglage du jeu entre ce tube et son tourillon. De plus, la notion de berceau est totalement exclue dans ce type de montage.GB-2 237 622 describes a guide device a weapon tube to prohibit the raising of the tube when firing. This guide includes four grooves in the trunnion and receiving tabs integral with the tube. The tube is therefore inserted into the trunnion, which precludes any possibility of adjusting the clearance between this tube and its journal. In addition, the concept of cradle is totally excluded in this type of assembly.

Le but de la présente invention est de pallier cet inconvénient en proposant un nouveau système de guidage d'une masse reculante par rapport à des glissières permettant de supprimer et rattraper le jeu latéral entre la glissière et le traíneau.The purpose of the present invention is to overcome this disadvantage by proposing a new guidance system for a receding mass with respect to slides allowing remove and make up for the lateral play between the slide and the sled.

L'invention a donc pour objet un système de guidage de la masse reculante d'une artillerie par rapport à son berceau, la masse reculante étant équipée d'un traíneau coulissant par rapport à des patins, le traíneau étant muni d'un rail incorporant une rainure dans laquelle est disposé le patin de manière coulissante, la rainure ayant un profil interdisant l'extraction latérale du patin hors de celle-ci, caractérisé en ce que les patins sont fixés à deux glissières latérales, chaque patin étant lui-même solidaire d'un support fixé à chaque glissière, le support du patin étant fixé par vissage à la glissière par l'intermédiaire d'un écrou vissé sur le support, le jeu (d) séparant le patin de la glissière étant réglable.The subject of the invention is therefore a system for guiding the receding mass of an artillery in relation to its cradle, the receding mass being equipped with a sliding sled by compared to skates, the sled being provided with a rail incorporating a groove in which the shoe is placed sliding way, the groove having a profile preventing lateral extraction of the skid out of it, characterized in that the pads are attached to two side rails, each shoe itself being integral with a support fixed to each slide, the pad support being fixed by screwing to the slide by means of a nut screwed on the support, the clearance (d) separating the shoe from the slide being adjustable.

Selon une première caractéristique, le patin présente deux paires de portées délimitant chacune un V en vis à vis et la rainure présente une forme complémentaire du profil du patin en comportant deux paires de portées complémentaires délimitant chacune un V en vis à vis.According to a first characteristic, the skate has two pairs of spans each delimiting a V opposite and the groove has a shape complementary to the profile of the skate with two pairs of complementary scopes each delimiting a V opposite.

Avantageusement, l'écrou est maintenu par une rondelle d'arrêt, permettant un réglage par vissage du jeu (d) entre le patin et la glissière.Advantageously, the nut is maintained by a washer stop, allowing adjustment by screwing the clearance (d) between the skate and the slide.

Préférentiellement, le patin est réalisé en bronze, est de forme sensiblement parallélépipédique et comporte un chanfrein arrière destiné à faciliter la mise en place de la masse reculante sur les glissières. Preferably, the skate is made of bronze, is of substantially parallelepiped shape and includes a rear chamfer intended to facilitate the installation of the receding mass on the slides.

Selon une autre caractéristique, le patin comporte un orifice sensiblement rectangulaire et un lamage également de forme rectangulaire, orifice et lamage ayant même largeur et les milieux de leurs longueurs confondus.According to another characteristic, the skate has a substantially rectangular orifice and a counterbore also of rectangular shape, hole and counterbore having the same width and the midpoints of their lengths combined.

Selon encore une autre caractéristique, le support comporte un axe cylindrique muni d'un filetage destiné à recevoir l'écrou et d'une encoche destinée à permettre l'arrêt en rotation de la rondelle.According to yet another characteristic, the support has a cylindrical axis provided with a thread intended for receive the nut and a notch intended to allow the washer stops rotating.

Avantageusement le support comporte deux portées cylindriques tronquées tangentiellement par deux méplats et destinées à coopérer en s'ajustant respectivement à l'intérieur du lamage et de l'orifice.Advantageously, the support has two spans cylindrical tangentially truncated by two flats and intended to cooperate by adjusting respectively to the inside of the counterbore and the orifice.

Selon une autre caractéristique, la glissière comporte un alésage destiné à recevoir l'axe cylindrique du support et une rainure longitudinale disposée en regard des méplats de la portée cylindrique du support et aménageant un jeu entre méplats et glissière. According to another characteristic, the slide comprises a bore intended to receive the cylindrical axis of the support and a longitudinal groove arranged opposite the flats of the cylindrical range of the support and providing a clearance between flats and slide.

Avantageusement, le support peut osciller autour de l'axe par rapport à la glissière, l'ajustement entre l'alésage de la glissière et l'axe du support de patin étant glissant.Advantageously, the support can oscillate around the axis relative to the slide, the adjustment between the bore of the slide and the axis of the skate support being sliding.

Un tout premier avantage de l'invention réside dans le fait que le positionnement latéral du traíneau par rapport aux glissières est tout à fait maítrisé. Il en résulte une fidélité du positionnement de rentrée en batterie de la masse reculante à chaque tir.A very first advantage of the invention lies in the causes the lateral positioning of the sled relative to with the slides is completely under control. This results in a fidelity of the mass reentry positioning recoiling with each shot.

Un autre avantage réside dans le fait que le système permet un rattrapage du jeu introduit par l'usure.Another advantage is that the system allows the play introduced by wear to be taken up.

Un autre avantage réside dans l'absence de déformation par écartement des glissières.Another advantage is the absence of deformation by spacing of the slides.

Un autre avantage réside dans le fait que l'usure des patins est uniforme.Another advantage is that the wear of the skates is uniform.

Un autre avantage réside dans le fait que le système permet la déformation du traíneau lors du tir.Another advantage is that the system allows the deformation of the sled when fired.

D'autres caractéristiques, détails et avantages de l'invention ressortiront plus clairement à la lecture du complément de description qui va suivre de modes de réalisation en relation avec des dessins sur lesquels :

Comme indiqué précédemment, la masse reculante d'une artillerie est animée d'un mouvement de va-et-vient par rapport au berceau et sur la figure 1 on a représenté une réalisation classique où l'on a partiellement représenté un traíneau 1 destiné à recevoir le tube de l'arme (non représenté). Le traíneau est muni d'une rainure 2 qui reçoit un patin 4 rendu solidaire de la glissière 3 par un pion 5. Dans cette configuration, il n'est pas possible de régler la valeur du jeu J entre le patin 4 et la rainure 2. L'usure inévitable du patin entraínera une modification de ce jeu qui ne pourra être rattrapé. Il en résultera une imprécision du positionnement de la masse reculante par rapport au berceau.As previously indicated, the receding mass of a artillery is moved back and forth by relative to the cradle and in Figure 1 there is shown a classic realization where we partially represented a sled 1 intended to receive the barrel of the weapon (not represented). The sled is provided with a groove 2 which receives a shoe 4 made integral with the slide 3 by a pin 5. In this configuration, it is not possible to adjust the value of clearance J between shoe 4 and groove 2. Wear inevitable skating will cause a modification of this game which cannot be caught. This will result in imprecision of the positioning of the receding mass relative to the cradle.

Sur la figure 3, on a représenté aux fins de compréhension de l'invention une vue d'un traíneau 15, selon l'invention, entourant le tube de l'arme M (non représenté) et muni de passages P1-P4 destinés à recevoir les freins hydrauliques de la masse reculante. De façon connue, la masse reculante comporte un traíneau muni selon l'invention de deux entailles 16 symétriques dans lesquelles un rail 17 est fixé par l'intermédiaire de vis 18. Chaque rail 17 est muni d'une rainure 19.In Figure 3, there is shown for the purpose of understanding of the invention a view of a sleigh 15, according to the invention, surrounding the barrel of the weapon M (not shown) and provided with passages P1-P4 intended to receive the brakes hydraulic of the recoiling mass. In known manner, the mass recoil comprises a sled provided according to the invention with two symmetrical notches 16 in which a rail 17 is fixed by means of screws 18. Each rail 17 is provided with a groove 19.

La figure 2 représente une vue' latérale du montage du traíneau 15. Le traíneau est constitué d'une partie avant 15a et d'une partie arrière 15b reliées par les rails 17. Le tube de l'arme n'est pas représenté.2 shows a side view of the mounting of the sled 15. The sled consists of a front part 15a and a rear part 15b connected by the rails 17. The tube of the weapon is not shown.

Sur la figure 3, on voit que la rainure 19 présente un profil de guidage comportant deux V. Cette rainure constitue une cage dans laquelle le patin introduit est emprisonné et son extraction interdite. En section radiale, la rainure 19 présente sur la figure deux paires de portées (20a, 21a) et (20b, 21b) délimitant chacune un V en vis-à-vis. Bien entendu, on pourrait adopter dans la mise en oeuvre du système selon l'invention toute forme équivalente pourvu que celle-ci permette l'emprisonnement du patin.In Figure 3, we see that the groove 19 has a guide profile with two V. This groove constitutes a cage in which the inserted shoe is trapped and its extraction prohibited. In radial section, the groove 19 shows in the figure two pairs of staves (20a, 21a) and (20b, 21b) each delimiting a V opposite. Well of course we could adopt in the implementation of the system according to the invention any equivalent form provided that the latter allows imprisonment of the skate.

La figure 4 représente une coupe transversale partielle du montage du traíneau par rapport à sa glissière 10. Chaque glissière supporte un patin 22 fixé à celle-ci par un support 23 fixé à la partie massive 14 de la glissière par l'intermédiaire d'un écrou 24 vissé sur le support 23 et maintenu par une rondelle d'arrêt 25. Chaque patin 22 est réalisé préférentiellement en bronze.Figure 4 shows a partial cross section mounting the sled relative to its slide 10. Each slide supports a pad 22 fixed to the latter by a support 23 fixed to the massive part 14 of the slide by by means of a nut 24 screwed onto the support 23 and held by a locking washer 25. Each shoe 22 is preferably made of bronze.

Les figures 5 et 6 représentent le patin 22, dont la forme est sensiblement parallélépipédique, présentant deux paires de portées (26a, 27a) et (26b, 27b) délimitant chacune un V en vis à vis. Les portées 26 et 27 sont avantageusement de forme complémentaire aux portées 20 et 21 de la rainure 19 de chaque rail 17. Ainsi, lorsque le patin 22 est introduit dans la rainure 19, il est emprisonné dans celle-ci et son extraction latérale en est impossible. Le patin comporte un orifice 31 sensiblement rectangulaire et un lamage 32 également de forme rectangulaire, orifice et lamage ayant même largeur et les milieux de leurs longueurs confondus. Le patin 22 présente également un chanfrein arrière 33 destiné à faciliter la mise en place de la masse reculante sur les glissières 10.Figures 5 and 6 show the shoe 22, the shape is substantially parallelepiped, having two pairs of staves (26a, 27a) and (26b, 27b) each delimiting a V opposite. The ranges 26 and 27 are advantageously of complementary shape to the spans 20 and 21 of the groove 19 of each rail 17. Thus, when the shoe 22 is introduced in groove 19, it is trapped in it and its lateral extraction is impossible. The skate has a orifice 31 substantially rectangular and a counterbore 32 also of rectangular shape, orifice and counterbore having same width and the middle of their lengths combined. The pad 22 also has a rear chamfer 33 intended for facilitate the installation of the receding mass on the slides 10.

Les figures 7 et 8 représentent le support 23 du patin 22. Il comporte un axe cylindrique 28 muni d'un filetage 29 destiné à recevoir l'écrou 24 et d'une encoche 30 destinée à permettre l'arrêt en rotation de la rondelle 25. Le support 23 comporte deux portées cylindriques 33 et 34 tronquées tangentiellement par deux méplats 35 et 36. Ces deux portées tronquées 33 et 34 sont destinées à coopérer en s'ajustant respectivement à l'intérieur du lamage 32 et de l'orifice 31, comme représenté à la figure 4. Pour se faire, la largeur m entre les deux méplats est sensiblement égale à la largeur commune 1 de l'orifice 31 et du lamage 32 et le diamètre de la portée 33 est sensiblement égal à la longueur L2 du lamage 32 et le diamètre de la portée 34 est sensiblement égal à la longueur L1 de l'orifice 31.Figures 7 and 8 show the support 23 of the skate 22. It has a cylindrical axis 28 provided with a thread 29 intended to receive the nut 24 and a notch 30 intended to allow the washer 25 to stop rotating. The support 23 has two cylindrical spans 33 and 34 truncated tangentially by two flats 35 and 36. These two spans truncated 33 and 34 are intended to cooperate by adjusting respectively inside the counterbore 32 and the orifice 31, as shown in figure 4. To do this, the width m between the two flats is substantially equal to the width common 1 of orifice 31 and counterbore 32 and the diameter of the range 33 is substantially equal to the length L2 of the counterbore 32 and the diameter of the bearing surface 34 is substantially equal to the length L1 of orifice 31.

En référence à la figure 4, on voit que lorsque le patin 22 est fixé au support 23, le serrage de l'écrou 24 provoque le rapprochement du traíneau 15 de la glissière 10. Il persiste un jeu (d) entre patin et glissière qui sera avantageusement identique pour les deux glissières.Referring to Figure 4, we see that when the skate 22 is fixed to the support 23, tightening the nut 24 causes bringing the sled 15 closer to the slide 10. It there is still a game (d) between skate and slide which will advantageously identical for the two slides.

Sur la figure, on a représenté un patin 22 épousant la forme de la rainure 19, c'est-à-dire une forme de V renversé en section s'appliquant sur les portées 20 et 21 en vis-à-vis du rail 17 du traíneau, forme complémentaire du profil de la rainure 19. Le glissement du patin 22 dans la rainure 19 du rail 17 se fait alors sans jeu latéral du traíneau par rapport à la glissière, ce qui conduit à une fidélité de positionnement de rentrée en batterie.In the figure, a shoe 22 has been shown matching the shape of the groove 19, i.e. an inverted V shape in section applying to spans 20 and 21 opposite of the rail 17 of the sled, complementary shape to the profile of the groove 19. The sliding of the shoe 22 in the groove 19 of the rail 17 is then made without lateral play of the sled by compared to the slide, which leads to a fidelity of reentry positioning in battery.

On comprend que la structure selon l'invention ne permet pas un écartement des glissières.It is understood that the structure according to the invention does not allow not a spacing of the slides.

Le jeu pourra permettre de compenser l'usure du patin au fur et à mesure de son frottement dans la rainure 19, par un nouveau serrage de l'écrou 24.The game can compensate for the wear of the skate at as it rubs in groove 19, by a re-tightening the nut 24.

L'usure des patins 22 au fur et à mesure de leur frottement dans les rainures 19 peut être facilement rattrapée par simple serrage de l'écrou 24, et ceci symétriquement par rapport aux glissières et/ou au traíneau. Le jeu (d) entre patins et glissières permet de compenser cette usure.The wear of the pads 22 as they are friction in grooves 19 can be easily caught up by simply tightening the nut 24, and this symmetrically with respect to the slides and / or the sled. The clearance (d) between pads and slides allows to compensate this wear.

Sur la figure 4, on voit que la glissière 10 comporte un alésage 37 destiné à recevoir l'axe cylindrique 28 du support 23 de patin et également une rainure longitudinale 38 disposée en regard des méplats 35, 36 de la portée cylindrique 34 du support 23 et aménageant un jeu entre méplats et glissière. L'ajustement entre l'alésage 37 de la glissière et l'axe 28 du support de patin étant glissant, lors du recul et du retour en batterie de la masse reculante pendant un tir, le patin 22 et le support 23 peuvent osciller autour de l'axe 28 par rapport à la glissière 10. Cela permet de compenser la déformation du traíneau engendrée par le couple de dévirage lors du tir et également de faciliter l'intégration de la masse reculante sur les glissières. Cette oscillation des patins permet aussi de garantir une usure sensiblement uniforme de ceux-ci sur toute leur longueur. Les rainures 19 du traíneau glissent lors du recul sur les patins donnant à ces derniers un positionnement angulaire optimal du patin par rapport à la glissière. On compense ainsi les déformations du traíneau en répartissant à chaque fois l'usure sur toute la longueur des patins. Il en résulte une durée de vie supérieure pour le système de guidage.In Figure 4, we see that the slide 10 has a bore 37 intended to receive the cylindrical axis 28 of the support 23 of skate and also a longitudinal groove 38 arranged opposite the flats 35, 36 of the span cylindrical 34 of the support 23 and providing a clearance between flats and slide. The adjustment between bore 37 of the slide and the axis 28 of the skate support being sliding, during recoil and return to battery of the recoiling mass during a shot, the shoe 22 and the support 23 can oscillate around the axis 28 relative to the slide 10. This allows compensate for the deformation of the sled caused by the deflection torque when firing and also to facilitate the integration of the receding mass on the slides. This oscillation of the pads also guarantees wear substantially uniform thereof over their entire length. The grooves 19 of the sled slide when retreating on the pads giving them an optimal angular positioning of the shoe in relation to the slide. We compensate deformation of the sled by distributing each time wear along the entire length of the pads. This results in a longer service life for the guidance system.

La déformation du traíneau est limitée par la rainure longitudinale 38 dont les flancs servent de butées aux méplats 35, 36 de la portée 34 du support 23 en limitant l'angle de rotation du support de patin par rapport à la glissière 10.The deformation of the sled is limited by the groove longitudinal 38 whose sides serve as stops for flats 35, 36 of the span 34 of the support 23 by limiting the angle of rotation of the skate support relative to the slide 10.
