Description

Le secteur technique de la présente invention est celui des véhicules militaires d'aménagement de terrain et plus particulièrement ceux utilisant des outils d'aménagement de terrain montés à l'avant du véhicule et travaillant en coopération avec le mouvement d'avancement du véhicule.The technical sector of the present invention is that military terrain vehicles and more especially those using ground mounted at the front of the vehicle and working in cooperation with the movement of the vehicle.

Les véhicules civils d'aménagement de terrain munis d'un outil monté à l'avant et travaillant en coopération avec le mouvement d'avancement du véhicule sont bien connus. L'archétype d'un tel véhicule est le véhicule équipé d'une lame de bouteur encore nommé bulldozer. Ce véhicule est utilisé pour pousser des matériaux (terres, gravats,...) afin de les retirer d'un endroit que l'on veut nettoyer ou encore pour les accumuler en un endroit afin de créer un tas ou un talus. Pour bien utiliser un tel véhicule et son outil, le conducteur du véhicule doit embrasser dans son champ de vision la totalité de la zone de travail, à savoir l'outil et le terrain travaillé. Sur ce genre de véhicule, la présence de grands panneaux vitrés assure au conducteur une bonne visibilité. De plus, le conducteur étant placé à l'arrière du véhicule, le gabarit est restreint.Civilian landscaping vehicles equipped with a tool mounted at the front and working in cooperation with the vehicle movement are well known. The archetype of such a vehicle is the vehicle equipped with a bulldozer blade still named bulldozer. This vehicle is used to push materials (earth, rubble, ...) so to remove them from a place you want to clean or to accumulate them in one place to create a heap or a Bank. To properly use such a vehicle and its tool, the driver of the vehicle must kiss in his field of vision the entire work area, namely the tool and the ground worked. On this kind of vehicle, the presence large glass panels ensures the driver a good visibility. In addition, the driver being placed at the rear of the vehicle, the template is restricted.

Par contre, lorsque l'outil est monté sur un véhicule militaire, le conducteur est placé à l'avant dudit véhicule et les moyens de vision ne lui laissent qu'un faible champ de vision et les armements et la charge militaire requièrent l'espace au milieu et parfois à l'arrière du véhicule. Pour résoudre ce problème, on pourrait penser à placer l'outil dans une position relativement éloignée du véhicule. Ceci présente l'inconvénient majeur d'augmenter le gabarit du véhicule en longueur et de poser des problèmes lors d'évolutions en zones de terrain compartimentées (zones construites, zones boisées ou encombrées). Cet inconvénient apparaít faiblement dans le cas de véhicules civils où il est possible d'utiliser de grandes verrières verticales dégageant largement le champ de vision de le conducteur vers la zone de travail de l'outil, qui peut dans ce cas rester très proche du véhicule. Cet inconvénient apparaít avec une acuité beaucoup plus grande dans le cas d'un véhicule militaire. Un tel véhicule de par la forme de sa caisse, conditionnée par des besoins de protection des équipages, produit des masques importants dans le champ de vision de le conducteur. Ce champ de vision est plus ouvert dans une zone située plus en avant du véhicule du fait des besoins liés au pilotage du véhicule. Un gabarit réduit en phase de déplacement est encore plus nécessaire pour ce type de véhicule.On the other hand, when the tool is mounted on a vehicle military, the driver is placed at the front of the vehicle and the means of vision leave him only a weak field of vision and the weapons and the military charge require the space in the middle and sometimes the back of the vehicle. For solve this problem one might think to place the tool in a position relatively remote from the vehicle. This has the major disadvantage of increasing the size of the vehicle in length and pose problems when evolutions in compartmentalized zones (zones constructed, wooded or congested areas). This disadvantage appears weakly in the case of civilian vehicles where it is possible to use large vertical windows clearing the driver's field of vision to the area of work of the tool, which can in this case stay very close of the vehicle. This disadvantage appears with sharpness much larger in the case of a military vehicle. A such a vehicle by the shape of its box, conditioned by crew protection needs, produces masks important in the driver's field of vision. This field of vision is more open in an area further ahead of the vehicle due to the needs related to the steering of the vehicle. A reduced template in phase of displacement is even more necessary for this type of vehicle.

La présente invention vise à résoudre ce problème en proposant un véhicule militaire ne présentant pas l'inconvénient signalé.The present invention aims to solve this problem by proposing a military vehicle not presenting the reported inconvenience.

L'invention a pour objet un véhicule militaire d'aménagement de terrain comprenant une caisse, des trains de roulement chenillés ou à roues, un outil monté à l'avant dudit véhicule par l'intermédiaire d'un support de liaison, caractérisé en ce que le support comporte des moyens rétractables pour placer l'outil dans au moins deux positions, une première position de travail éloignée du véhicule et une seconde position de transport rapprochée du véhicule.The subject of the invention is a military vehicle landscaping including a crate, trains of Tracked or wheeled bearing, a tool mounted at the front said vehicle via a connection support, characterized in that the support comprises means retractable to place the tool in at least two positions, a first working position away from the vehicle and a second transport position close to the vehicle.

L'outil peut être un outil d'aménagement du terrain pour fonctionner en coopération avec le mouvement d'avancement dudit véhicule.The tool can be a land development tool for operate in cooperation with the movement of advancement said vehicle.

L'outil peut être actionné par l'effort de poussée produit par l'avancement dudit véhicule.The tool can be operated by pushing force produced by advancing said vehicle.

Selon une réalisation, les moyens rétractables sont constitués par un vérin télescopique.According to one embodiment, the retractable means are consisting of a telescopic cylinder.

Selon une autre réalisation, les moyens rétractables sont constitués de deux demi-bras, un premier demi-bras comportant à une de ses extrémités une première articulation avec la caisse du véhicule, et à l'autre extrémité une seconde articulation avec un second demi-bras porteur de l'outil, les demi-bras constituant les moyens pour placer l'outil dans les deux positions.According to another embodiment, the retractable means are consisting of two half-arms, a first half-arm comprising at one of its ends a first articulation with the vehicle body, and at the other end a second articulation with a second half-arm carrying the tool, the half-arm constituting the means to place the tool in the two positions.

Le premier demi-bras peut être muni d'une première motorisation agissant entre la caisse et celui-ci pour l'actionner en éloignement ou en rapprochement relativement à la caisse.The first half-arm can be equipped with a first motorization acting between the body and the latter for to move it away or in the box.

Avantageusement, la première motorisation est un vérin linéaire ou un moteur rotatif. Advantageously, the first motorization is a jack linear or rotary motor.

Selon une autre réalisation, le second demi-bras est muni d'une seconde motorisation agissant entre le premier demi-bras et celui-ci pour l'actionner relativement au premier demi-bras.In another embodiment, the second half-arm is provided a second motorization acting between the first half-arm and this one to operate it relatively to the first half-arm.

Avantageusement, la seconde motorisation est un vérin linéaire ou un moteur rotatif.Advantageously, the second motorization is a jack linear or rotary motor.

Selon encore une autre réalisation, le véhicule militaire comprend une troisième articulation disposée entre le support et l'outil pour orienter ce dernier, ladite troisième articulation étant motorisée.According to yet another achievement, the military vehicle comprises a third articulation disposed between the support and the tool to guide the latter, said third articulation being motorized.

Un tout premier résultat de la présente invention est de retrouver à volonté la distance pilote/outil favorable à la vision de cet outil tout en maintenant le gabarit lors des déplacements dans des limites raisonnables.A very first result of the present invention is find at will the pilot distance / tool favorable to the vision of this tool while maintaining the template travel within reasonable limits.

Un résultat du dispositif selon l'invention est de permettre de combiner les avantages pour le transport d'une position d'outil proche du véhicule et lui conférant un petit gabarit avec les avantages pour le travail d'une position d'outil éloignée du véhicule afin de placer ledit outil dans le champ de vision de le conducteur.A result of the device according to the invention is allow to combine the benefits for the transport of a tool position close to the vehicle and giving it a small template with the advantages for the work of a position tool remote from the vehicle to place said tool in the field of vision of the driver.

Un autre résultat du dispositif selon l'invention est dans le cas d'un outil chargeur, utilisé avec un moyen articulé et motorisé, d'autoriser des opérations de chargement en hauteur, par exemple à destination d'une benne.Another result of the device according to the invention is in the case of a loader tool, used with a medium articulated and motorized, to authorize loading height, for example to a bucket.

D'autres caractéristiques, détails et avantages de l'invention ressortiront plus clairement de la description détaillée donnée ci-après à titre indicatif en relation avec des dessins sur lesquels :

  • la figure 1 illustre schématiquement l'état de l'art pour un véhicule civil,
  • les figures 2 et 3 illustrent schématiquement un mode de réalisation d'un véhicule militaire avec un dispositif télescopique,
  • les figures 4 et 5 illustrent schématiquement un mode de réalisation d'un véhicule militaire avec un dispositif articulé, et
  • les figures 6 et 7 illustrent la motorisation du dispositif articulé d'un véhicule militaire.
Other characteristics, details and advantages of the invention will emerge more clearly from the detailed description given below as an indication in relation to drawings in which:
  • FIG. 1 schematically illustrates the state of the art for a civilian vehicle,
  • Figures 2 and 3 schematically illustrate an embodiment of a military vehicle with a telescopic device,
  • Figures 4 and 5 schematically illustrate an embodiment of a military vehicle with an articulated device, and
  • Figures 6 and 7 illustrate the motorization of the articulated device of a military vehicle.

Sur la figure 1, est présenté l'état de l'art. Un véhicule civil d'aménagement de terrain comprenant une caisse 1, repose sur des trains de roulement 2 pouvant être chenillés ou à roues comme illustré. Un conducteur 13, présent à bord du véhicule, assure le pilotage du véhicule lors des phases de transport, ainsi que l'utilisation de l'outil 3 lors des phases de travail. L'outil 3 ici représenté, à titre illustratif, est une lame de bouteur. Le support 4 liant l'outil 3 à la caisse 1 du véhicule est, dans l'état de l'art, un bras 5 unique ou équivalent. Un tel support 4 ne permet pas de rapprocher ou d'éloigner l'outil 3 de la caisse 1. Tout au plus une articulation 7 peut permettre de descendre l'outil 3 en contact avec le terrain ou de le relever.In Figure 1, is presented the state of the art. A civilian land development vehicle including a crate 1, is based on running gear 2 which can be tracked or wheeled as shown. A driver 13, present on board the vehicle, provides control of the vehicle during the transport phases, as well as the use of Tool 3 during the work phases. Tool 3 here shown, for illustrative purposes, is a bulldozer blade. The support 4 linking the tool 3 to the body 1 of the vehicle is, in the state of the art, a single arm or equivalent. Such support 4 does not bring the tool closer or further away 3 1. At most one hinge 7 can allow the tool 3 to come down into contact with the ground or raise it.

Les figures 2 et 3 illustrent un mode de réalisation d'un véhicule militaire d'aménagement de terrain selon l'invention. Un véhicule comprenant la caisse 1 repose sur des trains de roulement 2. Un conducteur 13, présent à bord du véhicule, assure le pilotage du véhicule lors des phases de transport, ainsi que l'utilisation de l'outil 3 lors des phases de travail. L'outil 3 ici représenté, à titre illustratif, est une lame de bouteur. Le support 4 liant l'outil 3 à la caisse 1 du véhicule comprend un vérin télescopique 5 lié à une extrémité à la caisse 1 et à l'autre extrémité à l'outil 3. Un tel moyen 4, comprenant un vérin télescopique 5, lorsqu'il est fermé (Cf. figure 2), permet de rapprocher l'outil 3 au plus près de la caisse 1 en réduisant ainsi au minimum le gabarit en longueur du véhicule militaire pour constituer des moyens rétractables. Ceci est particulièrement adapté aux phases de transport. Lorsqu'il est ouvert (Cf. figure 3) ce support 4, constitué par un vérin télescopique 5, permet d'éloigner l'outil 3 de la caisse 1 et de le placer ainsi dans le champ de vision du conducteur 13. Une fois ouvert, le support 4 est avantageusement maintenu en position par un moyen de blocage connu de l'homme de l'art. L'outil 3 peut alors travailler en coopération avec le mouvement d'avance du véhicule militaire. La fixation du support 4 au niveau de la caisse 1 peut comprendre une articulation 7, le cas échéant motorisée, permettant de faire varier la hauteur de l'outil par rapport au terrain. Le dispositif selon l'invention est ici représenté vu de côté. Selon le type d'outil 3, le support 4 comprend un vérin télescopique 5 ou plusieurs vérins similaires, placés parallèlement les uns aux autres, à la même hauteur. Ils se confondent donc dans une vue de côté. Il va de soi que ces multiples vérins 5 sont manoeuvrés de concert.Figures 2 and 3 illustrate an embodiment of a military terrain vehicle according to the invention. A vehicle comprising the body 1 rests on running gear 2. A driver 13, present on board of the vehicle, provides control of the vehicle during the phases transport, as well as the use of tool 3 during phases of work. Tool 3 here represented, as illustrative, is a bulldozer blade. The support 4 binder the tool 3 at the body 1 of the vehicle comprises a jack telescopic 5 linked at one end to the body 1 and to the other end to the tool 3. Such a means 4, comprising a jack telescopic 5, when closed (see Figure 2), allows bring tool 3 closer to box 1 while reducing thus at least the jig in length of the military vehicle to constitute retractable means. this is particularly suitable for transport phases. when is open (see Figure 3) this support 4, consisting of a telescopic jack 5, makes it possible to move the tool 3 away from the box 1 and thus place it in the field of view of the 13. Once opened, support 4 is advantageously held in position by a locking means known to those skilled in the art. Tool 3 can then work in cooperation with the advance movement of the military vehicle. Fixing the support 4 at the level of the body 1 can include a hinge 7, if necessary motorized, allowing to vary the height of the tool compared on the ground. The device according to the invention is here shown seen from the side. Depending on the type of tool 3, the support 4 includes a telescopic jack 5 or more cylinders similar, placed parallel to one another, to the same height. They are therefore confused in a side view. he It goes without saying that these multiple cylinders 5 are maneuvered from concert.

Les figures 4 et 5 illustrent un autre mode de réalisation préférentiel du véhicule militaire d'aménagement de terrain selon l'invention. Le véhicule militaire comprenant la caisse 1 repose sur des trains de roulement 2. Le conducteur 13 assure le pilotage du véhicule et l'outil 3 représenté, à titre illustratif, est une lame de bouteur. Le support 4, liant l'outil à la caisse 1 du véhicule, comprend deux demi-bras 6 et 9. Le premier demi-bras 6 est lié à une de ses extrémités à la caisse 1 au moyen d'une première articulation 7, et à l'autre extrémité à un second demi-bras 9 par l'intermédiaire d'une seconde articulation 8. Les deux demi-bras constituent les moyens rétractables. L'autre extrémité du second demi-bras 9 porte l'outil 3. Les axes des deux articulations 7 et 8 sont sensiblement parallèles entre eux. Un tel support 4, lorsqu'il est fermé (Cf. figure 4) par réduction de l'angle entre les deux demi-bras 6 et 9, permet de rapprocher l'outil 3 au plus près de la caisse 1 en réduisant ainsi au minimum le gabarit en longueur du véhicule militaire. Lorsqu'il est ouvert (Cf. figure 5) ce support 4, permet d'éloigner l'outil 3 de la caisse 1 et de le placer ainsi dans le champ de vision du conducteur 13. Une fois ouvert, le support 4 est avantageusement maintenu en position par un moyen de blocage connu de l'homme de l'art. L'outil 3 peut alors travailler en coopération avec le mouvement d'avance du véhicule militaire. Le dispositif selon l'invention est ici représenté vu de côté. Le support 4 et principalement la première articulation 7 autorisent de plus un réglage de la hauteur de l'outil 3 relativement au terrain. Figures 4 and 5 illustrate another mode of preferential realization of the military development vehicle field of the invention. The military vehicle comprising the body 1 rests on running gear 2. The driver 13 controls the vehicle and the tool 3 shown, for illustrative purposes, is a bulldozer blade. The support 4, linking the tool to the body 1 of the vehicle, comprises two half-arms 6 and 9. The first half-arm 6 is connected to a from its ends to the box 1 by means of a first articulation 7, and at the other end to a second half-arm 9 through a second hinge 8. Both half-arms constitute the retractable means. The other end of the second half-arm 9 carries the tool 3. The axes of the two joints 7 and 8 are substantially parallel between them. Such a support 4, when closed (see FIG. reduction of the angle between the two half-arms 6 and 9, allows bring the tool 3 closer to the body 1 in thus minimizing the vehicle's length gauge military. When it is open (see Figure 5) this support 4, allows the tool 3 to be moved away from the body 1 and placed there thus in the driver's field of vision 13. Once open, the support 4 is advantageously held in position by a blocking means known to those skilled in the art. Tool 3 can then work in cooperation with the movement in advance of the military vehicle. The device according to the invention is here shown from the side. Support 4 and mainly the first hinge 7 allow for more a height adjustment of the tool 3 relative to the ground.

Les figures 6 et 7 illustrent des modes de réalisation de la motorisation du support 4 articulé à deux demi-bras 6 et 9. Il est envisageable de ne prévoir aucune motorisation de la commande du support 4. Dans ce cas le conducteur 13 peut manoeuvrer l'outil 3, les deux demi-bras 6 et 9 à la main ou en déplaçant son véhicule militaire d'aménagement de terrain. Une fois la position de l'outil 3 souhaitée obtenue, le conducteur 13 fige cette position en bloquant les articulations 7, 8, par un moyen connu de l'homme de l'art (non représenté). Il est avantageux de faciliter la tâche de le conducteur 13 en motorisant tout ou partie du support 4. Il est ainsi possible de commander indépendamment la mobilité de chaque articulation 7 ou 8.Figures 6 and 7 illustrate embodiments of the motorization of the articulated support 4 with two half-arms 6 and 9. It is conceivable not to envisage any motorization of the control of the support 4. In this case the driver 13 can maneuver tool 3, both half-arms 6 and 9 by hand or by moving his military land development vehicle. Once the position of the desired tool 3 has been obtained, the driver 13 freezes this position by blocking joints 7, 8, by means known to those skilled in the art (not shown) It is advantageous to facilitate the task of the driver 13 by motorizing all or part of the support 4. It is thus possible to control the mobility independently of each articulation 7 or 8.

La figure 6 illustre une première motorisation 10 appliquée au niveau du premier demi-bras 6. Cette première motorisation 10 peut par exemple prendre deux formes alternatives. Elle peut être réalisée par un moteur rotatif agissant directement au niveau de la première articulation 7. Elle peut alternativement être réalisée par un actionneur linéaire, par exemple de type vérin. Une extrémité d'un tel actionneur est solidaire de la caisse 1 et la seconde est solidaire du premier demi-bras 6. Le déploiement ou le repliement d'un tel actionneur linéaire provoque la rotation du demi-bras 6 autour de la première articulation 7. La figure 6 présente une telle première motorisation 10 en position repliée pour le transport et la figure 7 la représente en position déployée pour le travail d'aménagement de terrain.FIG. 6 illustrates a first motorization 10 applied at the level of the first half-arm 6. This first motorization 10 can for example take two forms alternatives. It can be achieved by a rotary engine acting directly at the first joint 7. It can alternatively be performed by an actuator linear, for example of the cylinder type. One end of such actuator is integral with the body 1 and the second is integral with the first half-arm 6. The deployment or folding of such a linear actuator causes the rotation of the half-arm 6 around the first articulation 7. The FIG. 6 presents such a first motorization 10 in folded position for transport and figure 7 la represents in deployed position for landscaping work ground.

Il est possible de se contenter de l'unique motorisation 10. Le conducteur 13 utilise alors le déplacement du véhicule militaire pour positionner l'outil 3. En agissant sur le demi-bras 6 par l'intermédiaire de la motorisation 10, il peut amener l'outil 3 au contact avec le terrain. En reculant alors son véhicule militaire, le conducteur 13 produit une ouverture de l'angle entre les demi-bras 6 et 9. A contrario, en avançant le véhicule, il produit une fermeture de ce même angle. Il peut ainsi mobiliser la seconde articulation 8, cette dernière n'étant pas motorisée. It is possible to be satisfied with the unique motorization 10. The driver 13 then uses the movement of the vehicle to position the tool 3. By acting on the half-arm 6 through the motorization 10 it can bring the tool 3 in contact with the ground. Backing-up then his military vehicle the driver 13 produces a opening of the angle between the half-arms 6 and 9. In contrast, by advancing the vehicle, it produces a closure of the same angle. It can thus mobilize the second articulation 8, the latter is not motorized.

Il est possible d'ajouter une motoriser de la seconde articulation 8. Cette seconde motorisation 11 peut prendre au moins deux formes alternatives. Elle peut être réalisée par un moteur rotatif agissant directement au niveau de la seconde articulation 8. Elle peut alternativement être réalisée par un actionneur linéaire, par exemple de type vérin. Une extrémité d'un tel actionneur est solidaire du demi-bras 6 et la seconde est solidaire de l'autre demi-bras 9. Le déploiement ou le repliement d'un tel actionneur linéaire provoque la rotation du demi-bras 9, relativement au demi-bras 6, autour de la seconde articulation 8. La figure 6 présente une telle seconde motorisation 11 en position repliée pour le transport et la figure 7 la représente en position déployée pour le travail d'aménagement de terrain.It is possible to add a motorizer of the second articulation 8. This second motorization 11 can take least two alternative forms. It can be done by a rotary motor acting directly at the level of the second articulation 8. It can alternatively be performed by a linear actuator, for example of the type cylinder. One end of such an actuator is integral with the half-arm 6 and the second is secured to the other half-arm 9. The deployment or refolding of such an actuator linear rotation causes the rotation of the half-arm 9 relative to the half-arm 6, around the second articulation 8. FIG. 6 has such a second motor 11 in position folded for transport and Figure 7 represents it in deployed position for land development work.

Quel que soit le principe retenu pour le moyen 4, basé sur un vérin télescopique ou articulé comprenant deux demi-bras 6 et 9 articulés entre eux, il est possible d'intercaler entre l'extrémité distale du moyen 4 et l'outil 3 une troisième articulation 12 comme représentée sur les figures 2-5. Cette troisième articulation permet d'orienter l'outil 3 indépendamment du moyen 4. Cette troisième articulation 12 peut, le cas échéant, être motorisée. Les figures 6 et 7 montrent un dispositif sans cette troisième articulation 12 optionnelle.Whatever the principle retained for medium 4, based on on a telescopic or articulated jack comprising two half-arms 6 and 9 articulated between them, it is possible to interpose between the distal end of the means 4 and the tool 3 a third hinge 12 as shown in the figures 2-5. This third articulation makes it possible to orient the tool 3 independently of the middle 4. This third articulation 12 can, if necessary, be motorized. Figures 6 and 7 show a device without this third articulation 12 optional.

Différents outils peuvent bénéficier de l'invention. On cite, à titre illustratif, des outils 3 uniquement portés par le véhicule. Ainsi, un dispositif de forage est susceptible de pouvoir être éloigné du véhicule lors de son utilisation, afin de dégager le champ de vision de le conducteur 13. Une autre catégorie d'outils 3 est constituée par des outils utilisés en coopération avec le mouvement d'avancement du véhicule. On cite à titre illustratif un outil de marquage au sol, un outil d'épandage, un outil de balayage, un outil de taille ou de coupe de végétation, un outil de sablage, une fraise de déneigement, un outil de pose par déroulage de tapis de sol. Une autre catégorie d'outils 3 est constituée par les outils manoeuvrés grâce à l'effort de poussée produit par l'avancement du véhicule en réaction au contact de l'outil 3 avec le terrain. On cite à titre illustratif un outil lame de bouteur non orientable, un outil lame de bouteur orientable, un outil godet chargeur, un outil godet «4 en 1» (outil combinant les fonctions de lame, de godet et de preneur), un outil de déminage (par exemple de type charrue poussée), un outil de scarification, un outil de rainurage ou encore un outil lame de déneigement.Different tools can benefit from the invention. We by way of illustration, tools 3 only worn by the vehicle. Thus, a drilling device is likely to be able to be away from the vehicle during use, in order to clear the driver's field of vision. another category of tools 3 consists of tools used in cooperation with the movement of advancement vehicle. For illustrative purposes, a marking tool is soil, a spreading tool, a sweeping tool, a tool for cutting or cutting vegetation, a sanding tool, a snow removal cutter, a peel-off tool ground sheet. Another category of tools 3 is constituted by tools manipulated through the thrust effort produced by the advancement of the vehicle in response to contact with tool 3 with the field. We quote for illustrative purposes a non-orientable dozer blade tool, a blade tool steerable dozer, bucket loader tool, bucket tool "4 in 1" (tool combining the functions of blade, bucket and taker), a demining tool (for example of the type push plow), a scarification tool, a tool for grooving or a snow plow tool.
