Description

L'invention se rapporte à une unité mobile légère de tir au mortier, en particulier au mortier de grande puissance.The invention relates to a light mobile mortar fire unit, in particular high power mortar.

En raison de l'absence de système ou de mécanisme interne d'amortissement pour des tirs balistiques de grande portée, les mortiers présentent une force de recul au tir d'une valeur importante.Due to the absence of an internal damping system or mechanism for long-range ballistic fire, the mortars have a significant recoil force when fired.

La faible durée d'application de cette force la rend encore plus dangereuse pour le matériel porteur.The short duration of application of this force makes it even more dangerous for the carrier material.

De manière générale, un mortier est monté sur une plaque de base par l'intermédiaire de laquelle il prend appui au sol pendant le tir. Il est généralement positionné par l'intermédiaire d'un ensemble bipied. Pour stabiliser l'ensemble au moment du tir, la plaque présente un relief prononcé selon trois saillies en arêtes disposées en étoile dans les principales directions de poussée. L'ancrage de ce type de plaque de base dans le sol garantit une stabilité suffisante pour assurer une grande précision de tir. Dans le cas d'un mortier tracté et monté sur un train de deux roues, le mortier prend toujours appui sur la plaque de base et l'ensemble bipied est constitué par le train de roues. La plaque encaisse et transmet au sol l'énergie de recul avec une efficacité maximale.Generally, a mortar is mounted on a base plate by means of which it rests on the ground during the firing. It is generally positioned via a bipod assembly. To stabilize the assembly at the time of the firing, the plate has a pronounced relief according to three projections in edges arranged in a star in the main directions of thrust. The anchoring of this type of base plate in the ground guarantees sufficient stability to ensure high shooting accuracy. In the case of a mortar towed and mounted on a train of two wheels, the mortar is always supported on the base plate and the bipod assembly is constituted by the train of wheels. The plate collects and transmits the recoil energy to the ground with maximum efficiency.

A titre d'exemple de l'état de la technique, on cite le véhicule décrit dans le brevet CH-A-336 724 qui est un véhicule lourd ne comportant pas de châssis et dont la partie centrale s'abaisse pour venir en contact avec le sol. Malgré cet appui au sol, il faut prévoir des dispositifs complémentaires d'appui qui confèrent à ce véhicule lourd une difficulté et une lenteur exceptionnelle de mise en oeuvre.By way of example of the state of the art, the vehicle described in patent CH-A-336,724 is cited, which is a heavy vehicle not comprising a chassis and the central part of which lowers to come into contact with floor. Despite this support on the ground, it is necessary to provide additional support devices which give this heavy vehicle an exceptional difficulty and slowness of implementation.

Les nécessités du combat à distance avec riposte amènent, pour des raisons d'efficacité et de sécurité, à souhaiter des unités de tir individuelles automouvantes de grande mobilité.The necessities of long-range combat with retaliation lead, for reasons of efficiency and security, to wish for self-propelled firing units of great mobility.

La mobilité impose le choix d'un véhicule plutôt léger, alors que les véhicules porteurs lourds susceptibles de supporter sans casse le recul de ce type de mortier ne présentent que peu d' intérêt en raison de leurs dimensions constituant une cible de choix et de leur lenteur caractéristique.Mobility requires the choice of a rather light vehicle, while heavy load-bearing vehicles capable of supporting the recoil of this type of mortar without breakage are of little interest because of their dimensions constituting a target of choice and their characteristic slowness.

De plus, leur coût élevé ne permet pas à une nation de se constituer un parc suffisant pour assurer l'efficacité certaine d'une offensive au mortier.In addition, their high cost does not allow a nation to build up a sufficient fleet to ensure the sure effectiveness of a mortar offensive.

La présente invention permet de concilier les impératifs de coût, de mobilité et d'aptitude mécanique à résister sans bris à la poussée brutale et violente du recul d'un mortier.The present invention makes it possible to reconcile the imperatives of cost, mobility and mechanical ability to resist without breakage to the brutal and violent thrust of the retreat of a mortar.

Le but de l'invention est de conférer à une unité de tir la rapidité nécessaire de mise en batterie et d'évacuation de la zone de tir, de manière à ne pas constituer immédiatement après le tir une cible potentielle de riposte.The object of the invention is to give a firing unit the necessary rapidity to build up and evacuate the firing zone, so as not to constitute immediately after firing a potential target for retaliation.

A cet effet, la présente invention se rapporte à une unité de tir au mortier comprenant un véhicule porteur et un mortier monté sur une plaque de base caractérisée en ce que le véhicule porteur possède une suspension escamotable permettant la descente rapide du châssis et en ce que la plaque de base est reliée au châssis du véhicule par l'intermédiaire d'une liaison élastique.To this end, the present invention relates to a mortar firing unit comprising a carrier vehicle and a mortar mounted on a base plate characterized in that the carrier vehicle has a retractable suspension allowing the chassis to descend rapidly and in that the base plate is connected to the chassis of the vehicle via an elastic connection.

La mobilité assurant la vitesse efficace de sortie de la zone de tir et les caractéristiques tout terrain du véhicule porteur ainsi que sa rapidité de mise en oeuvre constituent les principaux avantages de l'invention.The mobility ensuring the effective exit speed from the firing zone and the all-terrain characteristics of the carrier vehicle as well as its speed of implementation constitute the main advantages of the invention.

De plus, le volume et le poids moindres de ce véhicule n'impliquent pas les prix de revient importants des unités lourdes susceptibles de porter également ce type d'armement.In addition, the lower volume and weight of this vehicle does not imply significant cost prices for heavy units capable of also carrying this type of armament.

L'unité mobile de tir selon l'invention se compose d'un véhicule léger porteur tout terrain, à trains de chenilles ou à trains de roues. Ce véhicule présente la particularité de posséder une suspension escamotable de type oléopneumatique, mécanique, électrique ou autre, permettant d'abaisser le châssis pour amener un support d'appui en contact avec le sol en position de tir, ledit support étant relié de façon élastique avec le châssis ou avec un autre support portant le mortier.The mobile firing unit according to the invention consists of a light all-terrain carrier vehicle, with crawler trains or with wheel trains. This vehicle has the particularity of having a retractable suspension of the oleopneumatic, mechanical, electrical or other type, making it possible to lower the chassis to bring a support support in contact with the ground in the firing position, said support being connected in an elastic manner. with the frame or with another support carrying the mortar.

Le premier mode de réalisation est représenté en figures de 1 à 4. Les figures suivantes concernent le deuxième mode de réalisation.The first embodiment is shown in figures from 1 to 4. The following figures relate to the second embodiment.

Bien que l'on ait choisi de représenter ces deux modes sur des véhicules distincts à trains de chenilles puis à trains de roues, il n'y a pas lieu de retenir une quelconque limitation sur le type de véhicule propre à chaque mode.Although we have chosen to represent these two modes on separate vehicles with crawler trains and then with wheel trains, there is no reason to retain any limitation on the type of vehicle specific to each mode.

En référence à la figure 1, l'unité mobile de tir selon l'invention se compose d'un véhicule léger porteur 1 tout terrain, qui peut être aussi bien à trains de chenilles ou à trains de roues. Un mortier 2 est monté articulé sur le véhicule par l'intermédiaire de son fût 3. Ce dernier repose par l'intermédiaire d'une articulation 4 à rotule sur une embase 5 solidaire d'une plaque de base 6 reliée à la partie centrale du châssis 7 du véhicule porteur 1.With reference to FIG. 1, the mobile firing unit according to the invention consists of a light all-terrain carrier vehicle 1, which can be either crawler trains or wheel trains. A mortar 2 is mounted articulated on the vehicle via its barrel 3. The latter rests via a ball joint 4 on a base 5 secured to a base plate 6 connected to the central part of the chassis 7 of the carrier vehicle 1.

Comme indiqué, une des principales caractéristiques selon l'invention consiste à prévoir une suspension escamotable du véhicule permettant de mettre rapidement la plaque de base 6 en contact avec le sol, ceci afin de prendre appui lors des tirs. Cette suspension permet également de remonter l'ensemble de la plaque et du mortier afin que l'unité puisse se dégager rapidement de l'emplacement de tir.As indicated, one of the main characteristics according to the invention consists in providing a retractable suspension of the vehicle making it possible to quickly put the base plate 6 in contact with the ground, this in order to take support during the shots. This suspension also allows the entire plate and mortar to be reassembled so that the unit can quickly disengage from the firing location.

Sur la figure 2, la plaque 6 est en contact avec le sol. Elle n'est pas liée rigidement au châssis 7 mais est dotée d'une liaison élastique 8 à effet d'amortissement. Cette liaison peut être, par exemple, réalisée par plusieurs enroulements parallèles d'un câble métallique. Elle autorise, lors du tir, un mouvement relatif de la plaque de base par rapport au châssis et permet de filtrer partiellement les efforts mécaniques transmis par le mortier.In Figure 2, the plate 6 is in contact with the ground. It is not rigidly linked to the chassis 7 but is provided with an elastic connection 8 with a damping effect. This connection can be, for example, made by several parallel windings of a metal cable. It allows, during the firing, a relative movement of the base plate relative to the chassis and makes it possible to partially filter the mechanical forces transmitted by the mortar.

Une forme de réalisation de cette suspension est représentée sur la figure 3. Elle comporte de chaque côté et sur chaque galet 9 du train de chenilles 10 un vérin 11 agissant par l'intermédiaire d'un levier 12 sur chaque bras de suspension adjacent 13 pour réduire la garde au sol en modifiant l'inclinaison de chaque bras vers l'horizontale. De cette manière, le véhicule peut s'affaisser rapidement pour permettre les opérations de tir.An embodiment of this suspension is shown in FIG. 3. It comprises on each side and on each roller 9 of the track train 10 a cylinder 11 acting by means of a lever 12 on each adjacent suspension arm 13 for reduce ground clearance by changing the tilt of each arm to the horizontal. In this way, the vehicle can collapse quickly to allow firing operations.

En fin de tir, et par mouvement inverse, le châssis remonte et l'unité de tir peut rouler en parcours tout terrain.At the end of the shot, and by reverse movement, the chassis goes up and the firing unit can roll in all terrain course.

Cette plaque de base 6 peut affecter des formes et des reliefs divers. A cet effet, on prévoit en particulier plusieurs nervures en forme de bêche 14 reliant des formes en crampon 15.This base plate 6 can affect various shapes and reliefs. To this end, provision is made in particular for several spade-shaped ribs 14 connecting crampon shapes 15.

Dans le cas où le véhicule effectue un tir sur un sol d'une grande dureté, on peut profiter de l'inertie apportée par la masse du véhicule pour supprimer totalement l'effet du rebondissement. Dans ce cas, le véhicule est en appui sur la plaque de base.In the event that the vehicle makes a shot on very hard ground, one can take advantage of the inertia provided by the mass of the vehicle to completely eliminate the effect of rebounding. In this case, the vehicle is supported on the base plate.

Par contre, sur un sol plus meuble, la masse du véhicule peut favoriser l'ancrage et, par conséquent, la stabilisation de la plaque de base sur le sol et éviter, lors d'un tir à incidence faible, de subir un glissement ou un ripage.On the other hand, on a more soft ground, the mass of the vehicle can favor the anchoring and, consequently, the stabilization of the base plate on the ground and avoid, during a shooting at low incidence, to undergo a sliding or a shift.

De façon générale, l'invention permet de manière efficace d'atténuer les effets violents de l'onde de choc consécutive au tir, effets qui se transmettent pratiquement intégralement au sol.In general, the invention makes it possible effectively to attenuate the violent effects of the shock wave following the shooting, effects which are transmitted almost entirely to the ground.

Sur la figure 4, on voit, de façon plus détaillée, la manière selon laquelle l'ensemble formé du mortier 1 et de la plaque de base 6 peut être monté de manière élastique sur le véhicule. La liaison élastique 8 peut être assurée à l'aide d'au moins deux enroulements 16 et 17 d'un câble métallique constituant des anneaux élastiques reliés entre eux par des éléments transversaux. La plaque 6 pend légèrement par rapport au châssis 7, de sorte que, lorsque le véhicule s'affaisse par l'intermédiaire de la suspension escamotable, la plaque de base arrive systématiquement en contact avec le sol.In Figure 4, we see, in more detail, the manner in which the assembly formed by the mortar 1 and the base plate 6 can be mounted resiliently on the vehicle. The elastic connection 8 can be ensured by means of at least two windings 16 and 17 of a metal cable constituting elastic rings connected to one another by transverse elements. The plate 6 hangs slightly relative to the chassis 7, so that, when the vehicle collapses by means of the retractable suspension, the base plate systematically comes into contact with the ground.

L'embase 5 est solidaire de la plaque de base 6 par l'intermédiaire d'une liaison mécanique renforcée améliorant la solidité de la liaison entre la base du mortier et ladite plaque.The base 5 is secured to the base plate 6 by means of a reinforced mechanical connection improving the solidity of the connection between the base of the mortar and said plate.

Un exemple type de cette suspension est représenté en figure 5. Il sera décrit en détail ci-après.A typical example of this suspension is shown in Figure 5. It will be described in detail below.

L'autre mode de réalisation représenté en figures de 5 à 8 consiste à adapter le fût du mortier sur une plaque d'embase 18 supportée par le châssis sur lequel elle est montée flottante, par exemple par une suspension à liaison élastique du même type que précédemment, c'est-à-dire sous la forme des deux enroulements transversaux 16 et 17 et spirale d'un câble métallique dont les spires sont reliées entre elles par des éléments-supports longitudinaux hauts 19 et bas 20 solidaires respectivement de la plaque d'embase 18 du mortier et de deux structures saillantes 21 et 22 conformées dans ou rapportées sur le fond 23 du châssis 7 du véhicule porteur.The other embodiment shown in figures from 5 to 8 consists in adapting the barrel of the mortar on a base plate 18 supported by the chassis on which it is mounted floating, for example by an elastic connection suspension of the same type as previously, that is to say in the form of two transverse windings 16 and 17 and spiral of a metal cable whose turns are connected together by longitudinal support elements high 19 and low 20 secured respectively to the plate d 'base 18 of the mortar and two projecting structures 21 and 22 shaped in or attached to the bottom 23 of the chassis 7 of the carrier vehicle.

Les enroulements 16 et 17 seront disposés de préférence transversalement au véhicule l'un à l'avant, l'autre à l'arrière sur toute la largeur du véhicule.The windings 16 and 17 are preferably arranged transversely to the vehicle, one at the front, the other at the rear over the entire width of the vehicle.

Les éléments-supports longitudinaux 19 et 20 sont des barettes pourvues de perforations transversales dans lesquelles passent les spires.The longitudinal support elements 19 and 20 are bars provided with transverse perforations through which the turns pass.

On a réalisé ainsi un ensemble de suspension élastique particulier qui présente une fonction d'auto amortissement très efficace permettant de neutraliser entièrement et rapidement tous les effets oscillatoires engendrés par le tir.A particular elastic suspension assembly has thus been produced which has a very effective self-damping function which makes it possible to completely and quickly neutralize all the oscillatory effects generated by the shot.

Comme on peut le voir sur la figure 8, en position de tir, la suspension du véhicule s'affaisse jusqu'à contact du fond 23 de châssis avec le sol pour la réalisation de la surface d'appui et de stabilisation latérale au sol.As can be seen in FIG. 8, in the firing position, the suspension of the vehicle collapses until it contacts the bottom 23 of the chassis with the ground to produce the support and lateral stabilization surface on the ground.

La surface totale du fond constituant l'appui au sol mais surtout la suspension élastique à fonction d'autoamortissement très prononcée suffisent à supporter sans dommage les efforts mécaniques et l'onde de choc consécutifs au tir même sous incidence faible.The total surface of the bottom constituting the ground support but above all the elastic suspension with a very pronounced self-damping function is sufficient to withstand without damage the mechanical forces and the shock wave following the firing even under low incidence.
