Titre de l'invention : Dispositif anti-encastrement et véhicule pourvu d’un tel dispositif anti-encastrement Title of the invention: Anti-underrun device and vehicle provided with such an underrun device
Domaine technique de l’invention Technical field of the invention
La présente invention concerne un dispositif anti-encastrement notamment pour un véhicule du type camion ou poids lourd. The present invention relates to an anti-underrun device, in particular for a vehicle of the truck or heavy goods vehicle type.
En particulier, ce genre de véhicule comporte à l’arrière une portion en porte-à-faux située à un niveau plus élevé que celui des habitacles des véhicules dits de tourisme ou plus communément appelés automobiles. Conformément à certaines réglementations routières, le dispositif anti-encastrement comporte une barre anti-encastrement positionnée, sous la portion en porte-à-faux, à une certaine hauteur du sol et à une certaine distance de l’arrière du véhicule sur lequel le dispositif anti-encastrement est monté, de sorte à éviter que l’habitacle d’une automobile ne s’encastre sous ladite portion en porte-à-faux du véhicule du type camion ou poids lourd. In particular, this type of vehicle comprises at the rear a cantilevered portion located at a higher level than that of the passenger compartments of so-called passenger vehicles or more commonly called automobiles. In accordance with certain road regulations, the underrun device comprises an underrun bar positioned, under the overhanging portion, at a certain height from the ground and at a certain distance from the rear of the vehicle on which the device anti-underrun is mounted, so as to prevent the passenger compartment of an automobile from fitting under said cantilevered portion of the vehicle of the truck or heavy goods vehicle type.
La présente invention concerne en outre un tel véhicule du type camion ou poids lourd, pourvu d’un tel dispositif anti-encastrement. The present invention further relates to such a vehicle of the truck or heavy goods vehicle type, provided with such an underride protection device.
Etat de la technique State of the art
On connaît du document FR 2855 121 un véhicule dont une portion s’étend en porte-à-faux à un niveau plus élevé que celui des habitacles d’automobiles, et un dispositif anti-encastrement comportant deux montants destinés à être fixés chacun de part et d’autre d’un châssis porteur du véhicule. Le dispositif anti-encastrement comporte en outre une barre anti-encastrement située à l’arrière du véhicule sous la portion en porte-à-faux, et deux consoles reliant chacune la barre anti-encastrement à l’un des montants. Document FR 2855 121 discloses a vehicle, a portion of which extends cantilevered at a higher level than that of motor vehicle interiors, and an anti-underrun device comprising two uprights each intended to be fixed on either side. and on the other side of a carrying frame of the vehicle. The underride protection device also comprises an underride protection bar located at the rear of the vehicle under the overhanging portion, and two brackets each connecting the underride protection bar to one of the uprights.
Chaque montant du dispositif anti-encastrement comporte un profilé plat destiné à être fixé sur le châssis porteur du véhicule, et une nervure saillant vers l’extérieur et orientée horizontalement. La nervure est fixée au profilé plat par soudure. Une tranche d’extrémité avant de chaque console, et une surface de la nervure forment ensemble des moyens de butée permettant d’interdire à chaque console de basculer vers le bas au-delà d’une certaine position, appelée position de service. Each upright of the underrun device comprises a flat profile intended to be fixed to the supporting frame of the vehicle, and a rib projecting outwards and oriented horizontally. The rib is fixed to the flat profile by welding. A front end edge of each console, and a surface of the rib together form abutment means making it possible to prevent each console to swing down beyond a certain position, called the service position.
Ainsi, lorsque le dispositif anti-encastrement est fixé sur le châssis porteur du véhicule, chaque console s’étend selon un angle d’inclinaison par rapport à l’horizontale et la barre anti-encastrement se trouve ainsi positionnée à une certaine hauteur du sol et une certaine distance de l’arrière du véhicule, sous la portion en porte-à-faux. Thus, when the underride protection device is fixed to the carrier frame of the vehicle, each bracket extends at an angle of inclination relative to the horizontal and the underride protection bar is thus positioned at a certain height from the ground. and some distance from the rear of the vehicle, below the overhanging portion.
Exposé de l’invention Disclosure of Invention
La présente invention vise à fournir un dispositif anti-encastrement d’un genre similaire, dont le montage en position de service est facilité. The present invention aims to provide an anti-underrun device of a similar type, the assembly of which in the service position is facilitated.
Elle propose à cet effet, selon un premier aspect, un dispositif anti encastrement comportant : une barre anti-encastrement transversale ; deux consoles longitudinales ayant chacune une extrémité avant et une extrémité arrière à laquelle est fixée la barre anti-encastrement ; et deux systèmes de fixation et d’interface, chacun étant configuré pour être fixé d’une part sur l’extrémité avant d’une des consoles respectives et d’autre part sur un châssis d’un véhicule. It proposes for this purpose, according to a first aspect, an underrun device comprising: a transverse underrun bar; two longitudinal consoles each having a front end and a rear end to which the underride protection bar is fixed; and two fixing and interface systems, each being configured to be fixed on the one hand to the front end of one of the respective consoles and on the other hand to a chassis of a vehicle.
Selon l’invention, chaque système d’interface et de fixation comporte une plaque interne configurée pour être fixée directement ou indirectement au châssis du véhicule, et une plaque externe assemblée à la plaque interne et configurée pour être fixée sur l’extrémité avant d’une des consoles respectives, la plaque externe comprend un élément de positionnement, la plaque interne comprend un élément de positionnement complémentaire configuré pour coopérer avec l’élément de positionnement de la plaque externe respective par complémentarité de forme, de sorte à positionner la console respective selon au moins une direction prédéterminée parmi un nombre fini de directions prédéterminées. According to the invention, each interface and fixing system comprises an internal plate configured to be fixed directly or indirectly to the chassis of the vehicle, and an external plate assembled with the internal plate and configured to be fixed to the front end of one of the respective consoles, the external plate comprises a positioning element, the internal plate comprises a complementary positioning element configured to cooperate with the positioning element of the respective external plate by form complementarity, so as to position the respective console according to at least one predetermined direction among a finite number of predetermined directions.
Grâce à la complémentarité de forme entre les éléments de positionnement et éléments de positionnement complémentaires des plaques externes et internes, il est possible d’orienter précisément les consoles du dispositif anti-encastrement selon au moins une direction prédéterminée. Cette orientation permet un positionnement angulaire des consoles qui peuvent ainsi s’étendre selon au moins un angle d’inclinaison prédéterminé par rapport à l’horizontale. Thanks to the complementary shape between the positioning elements and complementary positioning elements of the external and internal plates, it is possible to precisely orient the brackets of the underrun device in at least one predetermined direction. This orientation allows an angular positioning of the consoles which can thus extend according to at least a predetermined angle of inclination with respect to the horizontal.
En fonction du type de véhicule à équiper d’un dispositif anti- encastrement et donc de la hauteur souhaitée pour la barre anti-encastrement, les plaques internes et les plaques externes peuvent être préalablement façonnées, par exemple par usinage, moulage, ou forgeage. De cette manière, lors de leur assemblage, les consoles présentent toujours un même positionnement angulaire ou des mêmes positionnements angulaires si plusieurs directions d’orientation des consoles sont permises par la forme des éléments de positionnement et éléments de positionnement complémentaires. Depending on the type of vehicle to be fitted with an underrun protection device and therefore the desired height for the underrun bar, the internal plates and the external plates can be shaped beforehand, for example by machining, casting or forging. In this way, when they are assembled, the brackets always have the same angular positioning or the same angular positioning if several directions of orientation of the brackets are permitted by the shape of the positioning elements and complementary positioning elements.
L’angle d’inclinaison des consoles est fonction ici de la complémentarité de forme des éléments de positionnement et éléments de positionnement complémentaires, et non pas de l’opérateur réalisant le montage du dispositif anti-encastrement sur le véhicule. En d’autres termes, la complémentarité de forme permet un positionnement angulaire des consoles lors du montage du dispositif anti-encastrement sur le véhicule précis et reproductible. The angle of inclination of the consoles is a function here of the complementarity of form of the positioning elements and complementary positioning elements, and not of the operator carrying out the mounting of the underride protection device on the vehicle. In other words, the complementarity of form allows precise and reproducible angular positioning of the brackets when mounting the underride protection device on the vehicle.
Le nombre de directions prédéterminées est fonction de la forme des éléments de positionnement et éléments de positionnement complémentaires des plaques internes et externes. Il est avantageux de permettre plusieurs directions d’orientation pour les consoles afin de pouvoir s’adapter à un plus grand nombre de véhicules différents. Dans certaines applications en revanche, une seule direction d’orientation pour les consoles peut suffire, simplifiant ainsi le façonnage des plaques internes et externes. The number of predetermined directions depends on the shape of the positioning elements and complementary positioning elements of the internal and external plates. It is advantageous to allow several directions of orientation for the consoles in order to be able to adapt to a greater number of different vehicles. In some applications, however, a single orientation direction for the brackets may suffice, thus simplifying the shaping of the internal and external plates.
Des caractéristiques préférées particulièrement simples, commodes et économiques du dispositif anti-encastrement selon l’invention sont présentées ci-dessous. Particularly simple, convenient and economical preferred characteristics of the underride protection device according to the invention are presented below.
L’un parmi l’élément de positionnement de la plaque externe et l’élément de positionnement complémentaire de la plaque interne comprend une première denture, et l’autre parmi l’élément de positionnement de la plaque externe et l’élément de positionnement complémentaire de la plaque interne comprend une deuxième denture coopérant avec la première denture. One of the positioning element of the external plate and the complementary positioning element of the internal plate comprises a first toothing, and the other of the positioning element of the plate external and the complementary positioning element of the internal plate comprises a second toothing cooperating with the first toothing.
La forme en denture de l’élément de positionnement et de l’élément de positionnement complémentaire permet de positionner angulairement de manière particulièrement précise les consoles. The toothed shape of the positioning element and of the complementary positioning element makes it possible to position the consoles angularly in a particularly precise manner.
En outre, en fonction de l’orientation angulaire souhaitée des consoles, il est possible de dimensionner la première denture et la deuxième denture d’une manière adéquate. En particulier, il est possible de choisir la taille et le nombre de dents de la première denture et de la deuxième denture afin de permettre l’orientation des consoles selon différentes directions prédéterminées, In addition, depending on the desired angular orientation of the brackets, it is possible to dimension the first toothing and the second toothing in an adequate manner. In particular, it is possible to choose the size and the number of teeth of the first toothing and of the second toothing in order to allow the orientation of the consoles according to different predetermined directions,
La multiplicité du nombre de dents dans la première denture et la deuxième denture permet notamment une sélection plus fine de la position des consoles parmi une pluralité de directions prédéterminées. The multiplicity of the number of teeth in the first toothing and the second toothing allows in particular a finer selection of the position of the brackets from a plurality of predetermined directions.
Par ailleurs, un tel mécanisme à dentures permet d’assembler de manière très simple les plaques internes et externes les unes avec les autres. Moreover, such a toothed mechanism makes it possible to assemble the internal and external plates with each other in a very simple way.
Au surplus, un tel mécanisme à dentures a l’avantage de fournir une bonne reprise et une bonne transmission des efforts subis par la barre anti encastrement et les consoles. Moreover, such a toothed mechanism has the advantage of providing good absorption and good transmission of the forces undergone by the underride protection bar and the brackets.
L’un parmi l’élément de positionnement de la plaque externe et l’élément de positionnement complémentaire de la plaque interne peut être un disque comportant la première denture, l’autre parmi l’élément de positionnement de la plaque externe et l’élément de positionnement complémentaire de la plaque interne peut comprendre une ouverture au moins partiellement circulaire et ayant un contour au moins partiellement formé par la deuxième denture. La plaque externe peut comporter un flasque duquel saille le disque.One of the positioning element of the external plate and the complementary positioning element of the internal plate can be a disc comprising the first toothing, the other of the positioning element of the external plate and the element complementary positioning of the inner plate may comprise an at least partially circular opening and having a contour at least partially formed by the second toothing. The outer plate may include a flange from which the disk protrudes.
La plaque interne peut comprendre au moins un premier orifice de fixation, la plaque externe peut comprendre au moins une lumière s’étendant sur une longueur prédéterminée, et le dispositif anti-encastrement peut comporter en outre au moins un boulon d’assemblage traversant ledit au moins un premier orifice de fixation de la plaque interne et ladite au moins une lumière de la plaque externe de sorte à fixer la plaque interne sur la plaque externe. Grâce à la lumière qui s’étend sur une longueur prédéterminée, il est possible de choisir la position de la plaque externe par rapport à la plaque interne. Le nombre de positions possibles de la plaque externe sur la plaque interne dépend de la combinaison entre la longueur de la lumière et la coopération des éléments de positionnement et éléments de positionnement complémentaires. The inner plate may comprise at least one first fixing hole, the outer plate may comprise at least one slot extending over a predetermined length, and the underrun device may further comprise at least one assembly bolt passing through said at least one first orifice for fixing the inner plate and said at least one lumen of the outer plate so as to fix the inner plate on the outer plate. Thanks to the light which extends over a predetermined length, it is possible to choose the position of the outer plate with respect to the inner plate. The number of possible positions of the outer plate on the inner plate depends on the combination between the length of the light and the cooperation of the positioning elements and complementary positioning elements.
La plaque interne peut comprendre un ou plusieurs premiers orifices de transmission, le dispositif anti-encastrement peut comporter en outre une ou plusieurs clavettes traversant la plaque interne par le ou les premiers orifices de transmission et configurées pour venir au moins sensiblement en appui contre le châssis du véhicule. De telles clavettes peuvent favoriser la reprise d’efforts dits de cisaillement. The internal plate may comprise one or more first transmission orifices, the underride protection device may further comprise one or more keys passing through the internal plate via the first transmission orifice(s) and configured to come at least substantially into abutment against the chassis of the vehicle. Such wedges can promote the recovery of so-called shear forces.
Chaque système de fixation et d’interface peut comporter une pièce d’interface qui est configurée pour être fixée par une première face sur le châssis du véhicule et par une deuxième face opposée à la première face à l’une des plaques internes respectives. Each attachment and interface system may include an interface piece that is configured to be attached by a first side to the vehicle frame and by a second side opposite the first side to one of the respective inner plates.
La pièce d’interface peut comprendre au moins un deuxième orifice de fixation situé en regard dudit au moins un premier orifice de fixation de la plaque interne, et l’au moins un boulon d’assemblage traverse en outre l’au moins un deuxième orifice de fixation de la pièce d’interface. La pièce d’interface peut comprendre un ou plusieurs deuxièmes orifices de transmission situés en regard du ou des premiers orifices de transmission de la plaque interne, et la ou les clavettes traversent en outre le ou les deuxièmes orifices de transmission la pièce d’interface. The interface part may comprise at least one second fixing hole located opposite said at least one first fixing hole of the internal plate, and the at least one assembly bolt also passes through the at least one second hole fixing the interface part. The interface part may comprise one or more second transmission orifices located opposite the first transmission orifice(s) of the internal plate, and the key(s) also pass through the second transmission orifice(s) in the interface part.
La pièce d’interface peut comprendre un ou plusieurs trous traversants pour la fixation de la pièce d’interface au châssis par l’intermédiaire d’un ou plusieurs boulons de fixation, et au moins un logement dans lequel débouchent le ou les trous traversants et qui est prévu pour accueillir une ou plusieurs têtes de vis formant le ou les boulons de fixation. The interface part may comprise one or more through-holes for fixing the interface part to the chassis by means of one or more fixing bolts, and at least one housing into which the through-hole(s) open and which is provided to accommodate one or more screw heads forming the fixing bolt or bolts.
La pièce d’interface peut comporter plaque de liaison et une plaque de fixation solidaire de la plaque de liaison, avec le ou les trous traversants qui sont ménagés dans la plaque de fixation, et avec la plaque de liaison qui comprend au moins une fenêtre ménagée en vis-à-vis du ou des trous traversants et définissant l’au moins un logement. The interface part may comprise a connecting plate and a fixing plate integral with the connecting plate, with the through hole(s) which are formed in the fixing plate, and with the connecting plate which comprises at least one window arranged opposite the through-hole(s) and defining the at least one housing.
Le fait de scinder la pièce d’interface en une plaque de fixation et en une plaque de liaison qui sont ensuite rendues solidaires permet de simplifier la fabrication d’une telle pièce, d’une part en perçant dans la plaque de fixation au moins le ou les trous traversants et/ou le ou les deuxièmes orifices de transmission et/ou l’au moins un deuxième orifice de fixation et, d’autre part, en réalisant au moins un lamage dans la plaque de liaison pour y former l’au moins une fenêtre et ainsi l’au moins un logement. La plaque de fixation et la plaque de liaison peuvent être soudées l’une avec l’autre. The fact of splitting the interface part into a fixing plate and a connecting plate which are then made integral makes it possible to simplify the manufacture of such a part, on the one hand by drilling in the fixing plate at least the or the through holes and/or the second transmission orifice(s) and/or the at least one second fixing orifice and, on the other hand, by producing at least one counterbore in the connecting plate to form the at least one window and thus the at least one housing. The fixing plate and the connecting plate can be welded together.
Chaque console peut comprendre un tronçon avant et un tronçon arrière articulé au tronçon avant, le tronçon avant étant outre articulé par l’extrémité avant de la console respective à l’un des systèmes de fixation et d’interface respectifs, et le tronçon arrière étant outre articulé par l’extrémité arrière de la console respective à la barre anti-encastrement. Each console may comprise a front section and a rear section articulated to the front section, the front section being further articulated by the front end of the respective console to one of the respective fastening and interface systems, and the rear section being further articulated by the rear end of the respective console to the underride bar.
Les consoles sont mobiles entre une position de service dans laquelle les tronçons avant et arrière sont alignés dans le prolongement l'un de l'autre, et une position escamotée dans laquelle les tronçons avant et arrière sont repliés l’un sur l’autre en formant un angle aigu l'un par rapport à l'autre. Ainsi, la barre anti-encastrement est mobile entre une position inférieure lorsque les consoles sont en position de service, et une position supérieure relativement plus haute que la position inférieure, lorsque les consoles sont en position escamotée. Dans la position inférieure de la barre anti-encastrement, le dispositif anti- encastrement est dit en configuration déployée, tandis que dans la position supérieure de la barre anti-encastrement, le dispositif anti-encastrement est dit en configuration rétractée. The consoles are movable between a service position in which the front and rear sections are aligned in the extension of one another, and a retracted position in which the front and rear sections are folded one over the other in forming an acute angle to each other. Thus, the underride bar is movable between a lower position when the consoles are in the service position, and an upper position relatively higher than the lower position, when the consoles are in the retracted position. In the lower position of the underride bar, the underride device is said to be in the extended configuration, while in the upper position of the underride bar, the underride device is said to be in the retracted configuration.
C’est dans la configuration déployée du dispositif anti-encastrement que la barre anti-encastrement permet d’éviter l’encastrement des véhicules automobiles sous le véhicule équipé de ce dispositif. La configuration rétractée du dispositif anti-encastrement est utilisée pour ne pas gêner les opérations par exemple de levage d’une benne que peut comporter le véhicule équipé de ce dispositif. It is in the deployed configuration of the underride protection device that the underride protection bar makes it possible to prevent motor vehicles from underrunning under the vehicle equipped with this device. The retracted configuration of the underride guard is used so as not to interfere with operations by example of lifting a skip that the vehicle equipped with this device may have.
La barre anti-encastrement peut comporter plusieurs tronçons, dont un tronçon central situé entre deux tronçons latéraux et décalé axialement par rapport aux tronçons latéraux. The underride bar can comprise several sections, including a central section located between two lateral sections and offset axially with respect to the lateral sections.
L’invention vise également, selon un second aspect, un véhicule comportant un châssis dit porteur ayant au moins deux longerons, une portion en porte-à-faux du châssis, et un dispositif anti-encastrement tel que décrit ci- dessus. Chaque plaque interne est configurée pour être fixée, directement ou indirectement, sur l’un des longerons respectifs du châssis de sorte que la barre anti-encastrement s’étende sous la portion en porte-à-faux du châssis. The invention also relates, according to a second aspect, to a vehicle comprising a so-called carrier chassis having at least two longitudinal members, a cantilevered portion of the chassis, and an underride protection device as described above. Each inner plate is configured to be fixed, directly or indirectly, to one of the respective frame rails so that the underride bar extends under the cantilevered portion of the frame.

Les figures 1 et 2 représentent, partiellement, un véhicule 1 de type poids lourd ou camion. Figures 1 and 2 represent, partially, a vehicle 1 of heavy goods vehicle or truck type.
Le véhicule 1 comporte un châssis porteur 2 sur lequel est implanté un équipement à benne 3 basculante. Une portion 300 de la benne basculante, située à l’arrière du véhicule 1 , est en porte-à-faux du châssis porteur 2. The vehicle 1 comprises a carrier frame 2 on which is located a tilting bucket equipment 3. A portion 300 of the tipper, located at the rear of the vehicle 1, is cantilevered from the undercarriage 2.
Le véhicule 1 repose sur le sol par des roues 4, dont l’une est visible sur les figures. The vehicle 1 rests on the ground by wheels 4, one of which is visible in the figures.
Le châssis porteur 2 comporte deux longerons 200 sur lesquels est fixé un faux-châssis (non visible) appartenant à l’équipement. La figure étant prise de côté, un seul des deux longerons 200 est visible. The carrying frame 2 comprises two longitudinal members 200 on which is fixed a subframe (not visible) belonging to the equipment. The figure being taken from the side, only one of the two beams 200 is visible.
Chaque longeron 200 est par exemple un profilé en U. La benne 3 est généralement destinée à accueillir et transporter des matériaux, par exemple des matériaux de revêtement routier. Each spar 200 is for example a U-section. The bucket 3 is generally intended to accommodate and transport materials, for example road surfacing materials.
La benne 3 est ici une benne non amovible, c’est-à-dire configurée pour rester fixée au véhicule 1. La benne 3 est articulée sur le faux-châssis au moyen d’un dispositif d’articulation 303 situé à l’arrière du véhicule 1. Le dispositif d’articulation 303 comprend notamment un axe de pivotement transversal 304. La benne basculante peut basculer vers l’arrière autour de l’axe de pivotement transversal 304. En particulier, la benne basculante peut occuper une position à platThe bucket 3 is here a non-removable bucket, that is to say configured to remain fixed to the vehicle 1. The bucket 3 is hinged to the subframe by means of a hinge device 303 located at the rear of the vehicle 1. The articulation device 303 comprises in particular a transverse pivot axis 304. The tipper body can tilt backwards around the transverse pivot axis 304. In particular, the tipper body can occupy a flat position
(comme à la figure 1) et une position inclinée (comme à la figure 2). La position à plat correspond à celle dans laquelle une tôle de fond 301 de la benne 3 est parallèle à une chaussée sur laquelle repose le véhicule 1. La position inclinée correspond à celle dans laquelle la tôle de fond 301 de la benne 3 s’étend dans un plan oblique par rapport à la chaussée. La benne 3 a une position inclinée maximale au-delà de laquelle elle ne peut basculer davantage vers l’arrière. (as in figure 1) and a reclined position (as in figure 2). The flat position corresponds to that in which a bottom plate 301 of the dump body 3 is parallel to a roadway on which the vehicle 1 is resting. The inclined position corresponds to that in which the bottom plate 301 of the dump body 3 extends in an oblique plane with respect to the roadway. Bucket 3 has a maximum tilted position beyond which it cannot tilt further back.
La benne 3 bascule de la position à plat à la position inclinée afin de déverser par l'arrière son contenu. Bucket 3 tilts from the flat position to the inclined position in order to dump its contents from behind.
Le basculement de la benne 3 de la position à plat à la position inclinée, et inversement, est effectuée par exemple au moyen d’un bras de levage formé par exemple par un vérin (non représenté sur les figures 1 et 2). The tilting of the bucket 3 from the flat position to the inclined position, and vice versa, is carried out for example by means of a lifting arm formed for example by a cylinder (not shown in Figures 1 and 2).
Le véhicule 1 des figures 1, 2 est équipé d’un dispositif anti encastrement 5. Vehicle 1 in Figures 1, 2 is fitted with an underride protection device 5.
Le dispositif anti-encastrement 5 est fixé au châssis porteur 2 de sorte à s’étendre sous la portion en porte-à-faux 300 de la benne 3. Comme il sera détaillé plus loin, le dispositif anti-encastrement 5 est configuré pour être fixé sur une face latérale 201 de chaque longeron 200. The anti-underrun device 5 is fixed to the carrying frame 2 so as to extend under the cantilevered portion 300 of the bucket 3. As will be detailed later, the underrun device 5 is configured to be fixed on a side face 201 of each spar 200.
Les figures 3, 4 diffèrent des figures 1, 2 uniquement par le type de benne 3 basculante. La benne 3 représentée aux figures 3, 4 est une benne amovible. Figures 3, 4 differ from Figures 1, 2 only by the type of dump body 3 tilting. The skip 3 shown in Figures 3, 4 is a removable skip.
On entend par benne amovible, une benne pouvant être fixée sur un véhicule ou être déposée librement sur d'autres structures. La benne amovible peut être fixée sur tout véhicule disposant d'un bras de levage 302 tel que visible sur la figure 4. Le bras de levage 302 est ici formé par un vérin. The term “removable container” means a container that can be attached to a vehicle or be placed freely on other structures. The removable bucket can be attached to any vehicle having a lifting arm 302 as shown in Figure 4. The lifting arm 302 is here formed by a cylinder.
Le véhicule 1 des figures 3, 4 est donc aussi équipé d’un dispositif anti-encastrement 5. Un tel dispositif anti-encastrement 5, mieux visible aux figures 5 à 8, comporte une barre anti-encastrement 6 transversale, deux consoles 7 longitudinales et deux systèmes de fixation et d’interface 8. The vehicle 1 of Figures 3, 4 is therefore also equipped with an anti-underrun device 5. Such an underrun device 5, better visible in Figures 5 to 8, comprises an anti-underrun bar 6 transverse, two consoles 7 longitudinal and two attachment and interface systems 8.
La barre anti-encastrement 6 comporte un tronçon central 600 et deux tronçons latéraux 601. Les tronçons latéraux 601 s’étendent de part et d’autre du tronçon central 600. Les tronçons latéraux 601 sont décalés axialement par rapport aux tronçons latéraux 601. Autrement dit, les tronçons latéraux 601 sont en retrait par rapport au tronçon central 600. The underride bar 6 comprises a central section 600 and two lateral sections 601. The lateral sections 601 extend on either side of the central section 600. The lateral sections 601 are offset axially with respect to the lateral sections 601. Otherwise said, the side sections 601 are set back from the central section 600.
La barre anti-encastrement 6 est mobile par rapport aux longerons 200 entre une position inférieure (figures 1, 3, 5, 6) et une position supérieure (figures 2, 4, 7, 8) relativement plus haute que la position inférieure. The underride bar 6 is movable relative to the beams 200 between a lower position (Figures 1, 3, 5, 6) and an upper position (Figures 2, 4, 7, 8) relatively higher than the lower position.
La barre anti-encastrement 6 se déplace de la position inférieure à la position supérieure, et inversement, par un mouvement de translation dans un plan P, dit plan de translation, incliné par rapport à l’horizontal (représenté aux figures 6, 8). The underride bar 6 moves from the lower position to the upper position, and vice versa, by a translation movement in a plane P, called translation plane, inclined with respect to the horizontal (shown in Figures 6, 8) .
Chaque console 7 comprend un tronçon avant 700 et un tronçon arrière 701. Each console 7 comprises a front section 700 and a rear section 701.
Le tronçon avant 700 et le tronçon arrière 701 sont par exemple des profilés en U. Chaque console 7 a une extrémité avant 702 et une extrémité arrièreThe front section 700 and the rear section 701 are for example U-sections. Each bracket 7 has a front end 702 and a rear end
703. L’extrémité avant 702 de chaque console 7 est fixée à un système de fixation et d’interface respectif 8. 703. The front end 702 of each console 7 is fixed to a respective fastening and interface system 8.
Plus précisément, le tronçon avant 700 est articulé par l’extrémité avant 702 de la console respective 7 au système de fixation et d’interface 8 correspondant. More specifically, the front section 700 is articulated by the front end 702 of the respective bracket 7 to the corresponding fastening and interface system 8.
Le tronçon avant 700 est articulé autour d’un axe avant 704 qui s'étend ici orthogonalement au plan de translation P. Le tronçon avant 700 et le tronçon arrière 701 sont articulés l’un par rapport à l’autre au niveau d’une jonction intermédiaire disposée entre l'extrémité avant 702 et l’extrémité arrière 703. The front section 700 is articulated around a front axis 704 which here extends orthogonally to the plane of translation P. The front section 700 and the rear section 701 are hinged relative to each other at an intermediate junction arranged between the front end 702 and the rear end 703.
Le tronçon avant 700 et le tronçon arrière 701 sont articulés autour d’un axe intermédiaire 706 à la jonction intermédiaire. L'axe intermédiaire 706 s'étend ici orthogonalement au plan de translation P. The front section 700 and the rear section 701 are articulated around an intermediate axis 706 at the intermediate junction. The intermediate axis 706 here extends orthogonally to the translation plane P.
Le tronçon arrière 701 est fixé à la barre anti-encastrement 6 par l’extrémité arrière 703 de la console respective 7. The rear section 701 is fixed to the underride bar 6 by the rear end 703 of the respective bracket 7.
En particulier, le tronçon arrière 701 est assujetti mécaniquement à un anneau 708 rigidement fixé autour du tronçon latéral respectif 601 sur la barre anti-encastrement 6. In particular, the rear section 701 is mechanically secured to a ring 708 rigidly fixed around the respective side section 601 on the underride bar 6.
Le tronçon arrière 701 est articulé autour d’un axe arrière 707 qui s'étend ici orthogonalement au plan de translation P. The rear section 701 is articulated around a rear axis 707 which here extends orthogonally to the plane of translation P.
Les consoles 7 sont ainsi mobiles entre une position de service (figures 1 , 3, 5, 6) et une position escamotée (figures 2, 4, 7, 8). The consoles 7 are thus movable between a service position (FIGS. 1, 3, 5, 6) and a retracted position (FIGS. 2, 4, 7, 8).
Dans la position de service, le tronçon avant 700 et le tronçon arrière 701 forment un angle ouvert l'un par rapport à l'autre. Plus précisément, le tronçon avant 700 et le tronçon arrière 701 sont ici alignés dans le prolongement l'un de l'autre. Dans la position escamotée, le tronçon avant 700 et le tronçon arrièreIn the service position, the front section 700 and the rear section 701 form an open angle with respect to each other. More precisely, the front section 700 and the rear section 701 are here aligned in the extension of one another. In the retracted position, the front section 700 and the rear section
701 forment un angle fermé l'un par rapport à l'autre. Plus précisément, le tronçon avant 700 et le tronçon arrière 701 sont ici repliés l’un sur l’autre en formant un angle aigu l'un par rapport à l'autre. 701 form a closed angle with respect to each other. More specifically, the front section 700 and the rear section 701 are here folded over one another forming an acute angle with respect to each other.
Lorsque les consoles 7 passent de la position de service à la position escamotée, les axes intermédiaires 706 des deux consoles 7 se déplacent latéralement vers l'extérieur du véhicule 1 , en s'éloignant l'un de l'autre. When the consoles 7 pass from the service position to the retracted position, the intermediate axes 706 of the two consoles 7 move laterally towards the outside of the vehicle 1, moving away from each other.
Le dispositif anti-encastrement 5 comprend des organes d’actionnement 10 sollicitant les tronçons avant 700 en rotation autour des axes avant 704 vers l'extérieur. Les organes d’actionnement 10 sont par exemple formés par deux vérins. Chaque organe d’actionnement 10 est fixé à l’une des consoles 7. En particulier, chaque organe d’actionnement 10 est ici, d’une part, assujetti mécaniquement par une première extrémité 1000 au tronçon avant 700, par exemple sur des pattes 705, et à proximité immédiate de la jonction intermédiaire et de l’un des axes intermédiaires 706, et d’autre part assujetti mécaniquement et articulé par une deuxième extrémité 1001 opposée à la première extrémité 1000 au système de fixation et d’interface 8. The anti-underrun device 5 comprises actuating members 10 urging the front sections 700 to rotate around the front axes 704 outwards. Actuators 10 are for example formed by two cylinders. Each actuating member 10 is fixed to one of the consoles 7. In particular, each actuating member 10 is here, on the one hand, mechanically secured by a first end 1000 to the front section 700, for example on tabs 705, and in the immediate vicinity of the intermediate junction and one of the intermediate axes 706, and on the other hand mechanically secured and articulated by a second end 1001 opposite the first end 1000 to the fastening and interface system 8.
Le dispositif anti-encastrement 5 est ainsi configuré pour prendre une configuration déployée et une configuration rétractée. Dans la configuration déployée, les consoles 7 sont en position de service et la barre anti-encastrement 6 en position inférieure. La configuration déployée convient notamment à la circulation routière puisque la barre anti encastrement 6 se trouve à un niveau intermédiaire entre la portion en porte-à- faux 300 du véhicule 1 et le sol. La barre anti-encastrement 6 est ainsi apte à éviter l’encastrement de véhicules automobiles sous la portion en porte-à-faux 300 du véhicule. The anti-underrun device 5 is thus configured to assume an extended configuration and a retracted configuration. In the deployed configuration, the brackets 7 are in the service position and the underride bar 6 in the lower position. The deployed configuration is particularly suitable for road traffic since the anti-underrun bar 6 is located at an intermediate level between the cantilevered portion 300 of the vehicle 1 and the ground. The anti-underrun bar 6 is thus able to prevent motor vehicles from underrunning under the cantilevered portion 300 of the vehicle.
Dans la configuration rétractée, les consoles 7 sont en position escamotée et la barre anti-encastrement 6 en position supérieure. La configuration rétractée convient notamment à une utilisation sur chantier. Elle permet par exemple d’éviter que la barre anti-encastrement 6 ne gêne le basculement de la benne 3. In the retracted configuration, the consoles 7 are in the retracted position and the underride bar 6 in the upper position. The retracted configuration is particularly suitable for use on the construction site. It makes it possible, for example, to prevent the anti-underrun bar 6 from interfering with the tipping of the bucket 3.
Le dispositif anti-encastrement 5 comporte également un capteur 11 sur l’un des systèmes de fixation et d’interface 8, comme visible à la figure 6 ou à la figure 9. Le capteur 11 est porté par un support 1100 fixé au système de fixation et d’interface 8. Le capteur 11 est configuré pour identifier la position dans laquelle se trouvent des consoles 7. En particulier, le capteur 11 est configuré pour identifier si les consoles 7 sont en position escamotée ou en position de service. Un tel capteur peut permettre de protéger le dispositif anti encastrement 5 en évitant par exemple que la benne 3 ne soit basculée vers l’arrière alors que le dispositif anti-encastrement 5 est en configuration déployée. Le capteur peut également servir à s’assurer que la barre anti encastrement 6 est en position de service lorsque le véhicule 1 est en circulation routière. The underrun device 5 also comprises a sensor 11 on one of the fixing and interface systems 8, as shown in FIG. 6 or in FIG. 9. The sensor 11 is carried by a support 1100 fixed to the system of fixing and interface 8. The sensor 11 is configured to identify the position in which the brackets 7 are located. In particular, the sensor 11 is configured to identify whether the brackets 7 are in the retracted position or in the service position. Such a sensor can make it possible to protect the anti-underrun device 5 by preventing, for example, the bucket 3 from being tipped backwards while the underrun protection device 5 is in the deployed configuration. The sensor can also be used to ensure that the underride bar 6 is in the service position when the vehicle 1 is in road traffic.
Les figures 9 à 12 représentent plus en détails l’un des systèmes de fixation et d’interface 8. Figures 9 to 12 represent in more detail one of the fastening and interface systems 8.
Le système d’interface et de fixation 8 comporte une plaque externeThe Interface and Fixing System 8 has an external plate
800, une plaque interne 801 assemblées avec la plaque externe 800, et une pièce d’interface 812 assemblées avec la plaque externe 800 et la plaque interne800, an internal plate 801 assembled with the external plate 800, and an interface piece 812 assembled with the external plate 800 and the internal plate
801, avec la plaque externe 801 qui est interposée entre la plaque externe 800 et la pièce d’interface 812. 801, with the outer plate 801 which is interposed between the outer plate 800 and the interface part 812.
La plaque externe 800 est configurée pour être fixée sur l’extrémité avant 702 d’une des consoles 7 respectives. The outer plate 800 is configured to be fixed on the front end 702 of one of the respective brackets 7.
La plaque externe 800, visible de manière isolée aux figures 13, 14, comprend un flasque 802. Le flasque 802 comprend au moins une lumière 803 s’étendant sur une longueur prédéterminée L. Le flasque 802 comprend ici six lumières 803. Les lumières 803 ont une forme oblongue. The external plate 800, visible in isolation in FIGS. 13, 14, comprises a flange 802. The flange 802 comprises at least one slot 803 extending over a predetermined length L. The flange 802 here comprises six slots 803. The slots 803 have an oblong shape.
Les lumières 803 permettent le réglage en position des plaque interne 801 et plaque externe 800 l’une par rapport à l’autre, comme expliqué plus loin. Le flasque 802 comprend également des ouvertures rectangulairesThe lights 803 allow the adjustment in position of the internal plate 801 and external plate 800 relative to each other, as explained later. The 802 flange also includes rectangular openings
822 et un trou circulaire 823 configurés pour la fixation de la console 7 respective par l’intermédiaire d’au moins une pièce de fixation (non représentée). 822 and a circular hole 823 configured for fixing the respective console 7 via at least one fixing piece (not shown).
La plaque externe 800 comprend un élément de positionnement 804. Dans l’exemple de réalisation représenté, l’élément de positionnement 804 de la plaque externe 800 comprend une première denture 805. The outer plate 800 comprises a positioning element 804. In the embodiment shown, the positioning element 804 of the outer plate 800 comprises a first toothing 805.
En particulier, la plaque externe 800 comporte un disque 806 saillant du flasque 802. Le disque 806 forme l’élément de positionnement 804 de la plaque externe 800. Le disque 806 comprend la première denture 805. In particular, the outer plate 800 includes a disk 806 projecting from the flange 802. The disk 806 forms the positioning element 804 of the outer plate 800. The disk 806 includes the first toothing 805.
La première denture 805 forme ici le pourtour du disque 806. Les lumières 803 de la plaque externe 800 se situent dans le flasqueThe first toothing 805 here forms the circumference of the disk 806. The slots 803 of the outer plate 800 are located in the flange
802 Les lumières 803 de la plaque externe 800 se situent autour du disque 806. Les lumières 803 se situent ainsi autour de la première denture 805. La plaque interne 801, visible de manière isolée à la figure 15, est configurée pour être fixée directement ou indirectement au châssis porteur 2 du véhicule 1. 802 The slots 803 of the outer plate 800 are located around the disc 806. The slots 803 are thus located around the first toothing 805. The internal plate 801, visible in isolation in Figure 15, is configured to be fixed directly or indirectly to the undercarriage 2 of the vehicle 1.
Dans l’exemple de réalisation représenté, la plaque interne 801 est fixée au châssis porteur 2 par l’intermédiaire d’une pièce d’interface 812. In the embodiment shown, the internal plate 801 is fixed to the support frame 2 via an interface piece 812.
La plaque interne 801 comprend au moins un premier orifice de fixation 807. La plaque interne 801 comprend ici six premiers orifices de fixation 807. The inner plate 801 comprises at least one first fixing hole 807. The inner plate 801 here comprises six first fixing holes 807.
Les premiers orifices de fixation 807 de la plaque interne 801 sont formés de sorte à se trouver chacun en regard d’une des lumières 803 de la plaque externe 800 lorsque la plaque interne 801 et la plaque externe 800 sont assemblées l’une à l’autre. The first fixing holes 807 of the internal plate 801 are formed so as to each be opposite one of the openings 803 of the external plate 800 when the internal plate 801 and the external plate 800 are assembled one to the other.
La plaque interne 801 comprend un ou plusieurs premiers orifices de transmission 808. La plaque interne 801 comprend ici sept premiers orifices de transmission 808. The inner plate 801 includes one or more first transmission holes 808. The inner plate 801 here includes seven first transmission holes 808.
La plaque interne 801 comprend un élément de positionnement complémentaire 809. The inner plate 801 includes a complementary positioning element 809.
L’élément de positionnement complémentaire 809 de la plaque interne 801 comprend une deuxième denture 810 coopérant avec la première denture 805. The complementary positioning element 809 of the internal plate 801 comprises a second toothing 810 cooperating with the first toothing 805.
Les six premiers orifices de fixation 807 et cinq parmi les premiers orifices de transmission 808 sont ici ménagés autour de la deuxième denture 810. Deux parmi les premiers orifices de transmission 808 sont ménagés à une extrémité distale de la deuxième denture 810. L’élément de positionnement complémentaires 809 de la plaque interne 801 comprend une ouverture 811. L’ouverture 811 est ici circulaire. Le contour de l’ouverture 811 est formé par la deuxième denture 810. The first six fixing holes 807 and five of the first transmission holes 808 are here made around the second toothing 810. Two of the first transmission holes 808 are made at a distal end of the second toothing 810. The complementary positioning 809 of the internal plate 801 comprises an opening 811. The opening 811 is circular here. The contour of the opening 811 is formed by the second toothing 810.
La première denture 805 est circonscrite à l'intérieur de la deuxième denture 810. Autrement dit, la première denture 805 est agencée à l'intérieur de la deuxième denture 810. Le nombre de dents de la première denture 805 est ainsi inférieur à celui de la deuxième denture 810. L’élément de positionnement 804 de la plaque externe 800 et l’élément de positionnement complémentaires 809 de la plaque interne 801 présentent une complémentarité de forme. L’élément de positionnement 804 de la plaque externe 800 et l’élément de positionnement complémentaires 809 de la plaque interne 801 peuvent ainsi coopérer ensemble. La coopération par complémentarité de forme entre l’élément de positionnement 804 de la plaque externe 800 et l’élément de positionnement complémentaire 809 de la plaque interne 801 permet de positionner la console 7 respective selon au moins une direction prédéterminée parmi une ou plusieurs directions prédéterminées. On entend ainsi par élément de positionnement 804 et élément de positionnement complémentaires 809, des éléments permettant par leur complémentarité de forme de bloquer la rotation des plaque interne 801 et plaque externe 800 l’une par rapport à l’autre. The first toothing 805 is circumscribed inside the second toothing 810. In other words, the first toothing 805 is arranged inside the second toothing 810. The number of teeth of the first toothing 805 is thus lower than that of the second toothing 810. The positioning element 804 of the external plate 800 and the complementary positioning element 809 of the inner plate 801 have a complementary shape. The positioning element 804 of the external plate 800 and the complementary positioning element 809 of the internal plate 801 can thus cooperate together. The cooperation by shape complementarity between the positioning element 804 of the external plate 800 and the complementary positioning element 809 of the internal plate 801 makes it possible to position the respective console 7 according to at least one predetermined direction among one or more predetermined directions. . The term positioning element 804 and complementary positioning element 809 is thus understood to mean elements allowing, by their complementary shape, to block the rotation of the internal plate 801 and external plate 800 with respect to each other.
Autrement dit, l’élément de positionnement 804 de la plaque externe 800 et l’élément de positionnement complémentaires 809 de la plaque interneIn other words, the positioning element 804 of the external plate 800 and the complementary positioning element 809 of the internal plate
801 permettent d’orienter la console 7 correspondante selon une ou plusieurs directions prédéterminées. En effet, la console 7 étant fixée par l’extrémité avant 702 à la plaque externe 800, le positionnement de la plaque externe 800 par rapport à la plaque inter 801, permet d’orienter angulairement la console 7. La console 7 forme ainsi un angle, dit angle d’inclinaison, avec un plan horizontal. 801 make it possible to orient the corresponding console 7 according to one or more predetermined directions. Indeed, the console 7 being fixed by the front end 702 to the external plate 800, the positioning of the external plate 800 with respect to the inter plate 801, makes it possible to orient the console 7 angularly. The console 7 thus forms a angle, called angle of inclination, with a horizontal plane.
Dans le mode de réalisation décrit ci-dessus et illustré, la première denture 805 et la deuxième denture 810 ont une denture fine ou autrement dit comprennent plusieurs dents. La première denture est une denture dite externe tandis que la deuxième denture est une denture dite interne. La multiplicité de dents permet un positionnement plus fin de la plaque externe 800 par rapport à la plaque interne 801. Cela permet donc une multitude de positions angulaires ou orientations selon des directions prédéterminées pour les consoles 7. Le positionnement angulaire des consoles 7, c’est-à-dire pour s’étendre selon une direction inclinée par rapport à l’horizontal, est ainsi plus précis. Le nombre de dents, leur taille et leur orientation peuvent être adaptés en fonction des besoins et notamment du nombre de positions angulaires souhaitées pour les consoles. In the embodiment described above and illustrated, the first toothing 805 and the second toothing 810 have fine toothing or in other words comprise several teeth. The first toothing is a so-called external toothing while the second toothing is a so-called internal toothing. The multiplicity of teeth allows a finer positioning of the outer plate 800 with respect to the inner plate 801. This therefore allows a multitude of angular positions or orientations according to predetermined directions for the consoles 7. The angular positioning of the consoles 7, it that is to say to extend in a direction inclined relative to the horizontal, is thus more precise. The number of teeth, their size and their orientation can be adapted according to the needs and in particular the number of angular positions desired for the brackets.
On notera que l’élément de positionnement 804 de la plaque externe 800 et l’élément de positionnement complémentaires 809 de la plaque interneIt will be noted that the positioning element 804 of the external plate 800 and the complementary positioning element 809 of the internal plate
801 peuvent plus généralement être de tout type et présenter toute forme du moment que leur complémentarité de forme permet le blocage en rotation des plaque interne 801 et plaque externe 800. La pièce d’interface 812 comprend une première face 813 (bien visible à la figure 12) configurée pour être fixée sur un longeron 200 du châssis porteur 2 du véhicule 1. La pièce d’interface 812 comprend également une deuxième face 814 (bien visible à la figure 11), opposée à la première face 813, et configurée pour être fixée à l’une des plaques internes 801 respectives. 801 can more generally be of any type and have any shape as long as their shape complementarity allows the internal plate 801 and external plate 800 to be locked in rotation. The interface part 812 comprises a first face 813 (clearly visible in FIG. 12) configured to be fixed on a side member 200 of the undercarriage 2 of the vehicle 1. The interface part 812 also comprises a second face 814 (clearly visible in FIG. 11), opposite the first face 813, and configured to be attached to one of the respective inner plates 801.
En particulier, la pièce d’interface 812 comprend une pluralité, ici six, deuxièmes orifices de fixation 815 situés chacun en regard d’un des premiers orifices de fixation 807 de la plaque interne 801. In particular, the interface part 812 comprises a plurality, here six, second fixing holes 815 each located opposite one of the first fixing holes 807 of the internal plate 801.
La pièce d’interface 812 comprend en outre un ou plusieurs trous traversants 816. Interface piece 812 further includes one or more through holes 816.
La pièce d’interface 812 comprend ici dix-huit trous traversants 816 bien visibles aux figures 12 et 17. Les dix-huit trous traversants 816 sont répartis selon trois séries, parallèles entre elles, de six trous traversants 816. The interface part 812 here comprises eighteen through-holes 816 clearly visible in Figures 12 and 17. The eighteen through-holes 816 are distributed according to three series, parallel to each other, of six through-holes 816.
La pièce d’interface 812 comprend également une pluralité, ici sept, deuxièmes orifices de transmission 817 situés chacun en regard d’un des premiers orifices de transmission 808 de la plaque interne 801. La pièce d’interface 812 comprend également au moins un logementThe interface part 812 also comprises a plurality, here seven, second transmission orifices 817 each located opposite one of the first transmission orifices 808 of the internal plate 801. The interface part 812 also comprises at least one housing
818 dans lequel débouchent les trous traversants 816. 818 into which the through holes 816 open.
La pièce d’interface 812 peut être formée en une seule pièce dans laquelle le logement 818 est formé, notamment par usinage. The interface part 812 can be formed in one piece in which the housing 818 is formed, in particular by machining.
Dans l’exemple de réalisation illustré, la pièce d’interface 812 comporte deux plaques distinctes. Ici, la pièce d’interface 812 comporte une plaque de liaison 819 (représentée isolément à la figure 16) et une plaque de fixation 820 (représentée isolément à la figure 17). La plaque de liaison 819 et la plaque de fixation 820 sont solidaires entre elles. La plaque de liaison 819 et la plaque de fixation 820 sont par exemple soudées l’une à l’autre. In the illustrated embodiment, the interface part 812 comprises two separate plates. Here, the interface part 812 includes a connecting plate 819 (shown in isolation in FIG. 16) and a fixing plate 820 (shown in isolation in FIG. 17). The connecting plate 819 and the fixing plate 820 are integral with each other. The connecting plate 819 and the fixing plate 820 are for example welded to each other.
La plaque de liaison 819 comprend deux fenêtres 821. Les trous traversants 816 sont ici ménagés dans la plaque de fixationThe connecting plate 819 comprises two windows 821. The through holes 816 are here formed in the fixing plate
820. 820.
Les deuxièmes orifices de transmission 817 et les deuxièmes orifices de fixation 815 sont quant à eux ménagés dans la plaque de liaison 819 et dans la plaque de fixation 820 et débouchent de part et d’autre des première et deuxième faces 813, 814 de la pièce d’interface 812. The second transmission orifices 817 and the second fixing orifices 815 are for their part made in the connecting plate 819 and in the fixing plate 820 and emerge on either side of the first and second faces 813, 814 of the part interface 812.
Par exemple, la plaque de liaison 819 et la plaque de fixation 820 peuvent être formées à partir de tôles découpées au laser. Un lamage est réalisé dans la plaque de liaison 819 pour former chaque fenêtre 821. Des perçages sont effectués dans la plaque de liaison 819 et la plaque de fixation 820 pour former les trous traversants 816, les deuxièmes orifices de transmission 817 et les deuxièmes orifices de fixation 815. For example, the link plate 819 and the fixing plate 820 can be formed from laser cut sheets. A counterbore is made in the link plate 819 to form each window 821. Drillings are made in the link plate 819 and the fixing plate 820 to form the through holes 816, the second transmission holes 817 and the second transmission holes. fixing 815.
La plaque de liaison 819 et la plaque de fixation 820 sont ensuite rendues solidaires de sorte que les fenêtres 821 soient en regard des trous traversants 816. En outre, les deuxièmes orifices de transmission 817 de la plaque de liaison 819 sont ménagés en regard des deuxièmes orifices de transmission 817 de la plaque de fixation 820. De même, les deuxièmes orifices de fixation 815 de la plaque de liaison 819 sont ménagés en regard des deuxièmes orifices de fixation 815 de la plaque de fixation 820. The connecting plate 819 and the fixing plate 820 are then made integral so that the windows 821 are opposite the through holes 816. In addition, the second transmission orifices 817 of the connecting plate 819 are made opposite the second transmission holes 817 of the fixing plate 820. Similarly, the second fixing holes 815 of the connecting plate 819 are arranged opposite the second fixing holes 815 of the fixing plate 820.
La disposition des fenêtres 821 de la plaque de liaison 819 en regard des trous traversants 816 de la plaque de fixation 820 permet de former le logement 818. The arrangement of the windows 821 of the connecting plate 819 opposite the through holes 816 of the fixing plate 820 makes it possible to form the housing 818.
La réalisation de la pièce d’interface 812 en deux plaques rend sa fabrication et en particulier son usinage pour la formation du logement 818 plus simple. En outre, cela donne plus de flexibilité pour s’adapter aux différents châssis sur lequel le dispositif anti-encastrement 5 peut être fixé. En effet, le nombre nécessaire de fixations du dispositif anti-encastrement 5 au châssis porteur 2, ainsi que leur disposition diffèrent d’un châssis à l’autre. La réalisation de la pièce d’interface 812 en deux plaques permet d’adapter uniquement la plaque de fixation 820 au châssis en modifiant par exemple la disposition et le nombre de trous traversants, et d’utiliser une même plaque de liaison 819 pour tout type de châssis. The realization of the interface part 812 in two plates makes its manufacture and in particular its machining for the formation of the housing 818 simpler. Furthermore, this gives more flexibility to adapt to the different frames on which the underride protection device 5 can be fixed. Indeed, the necessary number of fixings of the anti-underrun device 5 to the chassis carrier 2, as well as their arrangement differ from one chassis to another. The realization of the interface part 812 in two plates makes it possible to adapt only the fixing plate 820 to the chassis by modifying for example the arrangement and the number of through holes, and to use the same connecting plate 819 for any type of chassis.
Le dispositif anti-encastrement 5 comporte en outre des boulons d’assemblage 9 et des boulons de fixation 902. The anti-underrun device 5 further comprises assembly bolts 9 and fixing bolts 902.
Les boulons d’assemblage 9 traversent les premiers orifices de fixation 807 de la plaque interne 801 et les lumières 803 de la plaque externe 800. Les boulons d’assemblage 9 permettent l’assemblage de la plaque interneThe assembly bolts 9 pass through the first fixing holes 807 of the internal plate 801 and the openings 803 of the external plate 800. The assembly bolts 9 allow the assembly of the internal plate
801 et de la plaque externe 800 entre elles. 801 and the outer plate 800 between them.
Les boulons d’assemblage 9 traversent également ici les deuxièmes orifices de fixation 815 de la pièce d’interface 812 puisque la plaque interne 801 est fixée au châssis au moyen de la pièce d’interface 812. Les boulons d’assemblage 9 permettent l’assemblage entre elles de la plaque interne 801, la plaque externe 800 et la pièce d’interface 812. The assembly bolts 9 here also pass through the second fixing holes 815 of the interface part 812 since the internal plate 801 is fixed to the chassis by means of the interface part 812. The assembly bolts 9 allow the assembly between them of the inner plate 801, the outer plate 800 and the interface part 812.
Les boulons d’assemblage 9 peuvent servir à la fixation entre eux d’éléments du châssis porteur 2 du véhicule 1 en plus de permettre l’assemblage de la plaque externe 800, la plaque interne 801 et éventuellement la pièce d’interface 812. Par exemple, il peut s’agir de boulons permettant l’assemblage d’une traverse 202 (visible sur la figure 5) aux longerons 200. The assembly bolts 9 can be used to fix together elements of the undercarriage 2 of the vehicle 1 in addition to allowing the assembly of the outer plate 800, the inner plate 801 and possibly the interface part 812. By example, it may be bolts allowing the assembly of a crosspiece 202 (visible in Figure 5) to the beams 200.
Deux boulons parmi les boulons d’assemblage 9 servent également à la fixation du support 1100 pour le capteur 11 sur la plaque externe 800. Two bolts among the assembly bolts 9 are also used to fix the support 1100 for the sensor 11 on the external plate 800.
Les boulons de fixation 902 traversent les trous traversants 816 de la pièce d’interface 812. Les boulons de fixation 902 permettent la fixation de la pièce d’interface 812 au châssis porteur 2 du véhicule. The fixing bolts 902 pass through the through holes 816 of the interface part 812. The fixing bolts 902 allow the fixing of the interface part 812 to the undercarriage 2 of the vehicle.
Les logements 818 accueillent des têtes de vis 903 des boulons de fixation 902. Housings 818 accommodate screw heads 903 of fixing bolts 902.
Les boulons de fixation 902 permettent la reprise des efforts. Le nombre de boulons de fixation 902 utilisés dépend des efforts à reprendre. Le dispositif anti-encastrement 5 comporte en outre une ou plusieurs clavettes 901 (visibles par exemple à la figure 12). Le dispositif anti-encastrement 5 comporte ici sept clavettes 901. The fixing bolts 902 allow the forces to be taken up. The number of fixing bolts 902 used depends on the forces to be taken up. The anti-underrun device 5 further comprises one or more keys 901 (visible for example in FIG. 12). The anti-underrun device 5 here comprises seven keys 901.
Les clavettes 901 traversent les premiers orifices de transmission 808 de la plaque interne 801 et deuxièmes orifices de transmission 817 de la pièce d’interface 812. Les clavettes 901 viennent au moins sensiblement en appui contre le châssis porteur 2 du véhicule 1. The keys 901 pass through the first transmission orifices 808 of the internal plate 801 and second transmission orifices 817 of the interface part 812. The keys 901 come at least substantially into abutment against the undercarriage 2 of the vehicle 1.
Les clavettes 901 sont configurées pour reprendre les efforts de cisaillement. L’assemblage du dispositif anti-encastrement 5 sur le châssis porteurKeys 901 are configured to take up shear forces. Assembly of the underride protection device 5 on the carrier frame
2 du véhicule 1 s’effectue de la manière suivante. 2 of vehicle 1 is carried out as follows.
Des tiges 900 des boulons d’assemblage 9 sont passées dans la pièce d’interface 812, notamment au travers des deuxièmes orifices de fixation 815. Rods 900 of assembly bolts 9 are passed through interface part 812, in particular through second fixing holes 815.
La pièce d’interface 812 est ensuite fixée sur le châssis porteur 2 par les boulons de fixation 902 traversant les trous traversants 816. The interface part 812 is then fixed to the carrying frame 2 by the fixing bolts 902 passing through the through holes 816.
Au préalable de la fixation de la pièce d’interface 812, les clavettes 901 peuvent être introduites dans les deuxièmes orifices de transmission 817 de la pièce d’interface 812. Les clavettes 901 sont disposées de sorte à être en appui contre le châssis porteur 2 une fois la pièce d’interface 812 fixée sur le châssis porteur 2. Prior to fixing the interface part 812, the keys 901 can be introduced into the second transmission holes 817 of the interface part 812. The keys 901 are arranged so as to rest against the support frame 2 once the interface part 812 is fixed on the support frame 2.
Les deux parmi les deuxièmes orifices de transmission 817 en regard des deux premiers orifices de transmission 808 ménagée à l’extrémité distale de la plaque interne 801 peuvent recevoir chacun une bague (non représentées). Les bagues permettent d’éviter aux clavettes 901 d’être délogées desdits premiers orifices de transmission 808 et deuxièmes orifices de transmission 817. The two of the second transmission orifices 817 facing the two first transmission orifices 808 formed at the distal end of the internal plate 801 can each receive a ring (not shown). The rings make it possible to prevent the keys 901 from being dislodged from said first transmission orifices 808 and second transmission orifices 817.
Les boulons d’assemblage 9 sont passés au travers des premiers orifices de fixation 807 de la plaque interne 801. Les premiers orifices de fixation 807 de la plaque interne 801 sont ainsi en regard des deuxièmes orifices de fixation 815 de la pièce d’interface 812. Les clavettes 901 sont passées au travers des premiers orifices de transmission 808 de la plaque interne 801. Les premiers orifices de transmission 808 de la plaque interne 801 sont ainsi en regard des deuxièmes orifices de transmission 817 de la pièce d’interface 812. La plaque externe 800 est positionnée par rapport à la plaque interne 801 grâce à l’élément de positionnement 804 de plaque externe 800 et l’élément de positionnement complémentaires 809 de la plaque interne 801. The assembly bolts 9 are passed through the first fixing holes 807 of the internal plate 801. The first fixing holes 807 of the internal plate 801 are thus opposite the second fixing holes 815 of the interface piece 812 The keys 901 are passed through the first transmission orifices 808 of the internal plate 801. The first transmission orifices 808 of the internal plate 801 are thus opposite the second transmission orifices 817 of the interface part 812. The outer plate 800 is positioned relative to the inner plate 801 thanks to the positioning element 804 of the outer plate 800 and the complementary positioning element 809 of the inner plate 801.
Les tiges 900 des boulons d’assemblage 9 sont introduites dans les lumières 803 de la plaque externe 800. Les lumières 803 de la plaque externeThe rods 900 of the assembly bolts 9 are introduced into the slots 803 of the outer plate 800. The slots 803 of the outer plate
800 sont ainsi en regard des premiers orifices de fixation 807 de la plaque interne800 are thus opposite the first fixing holes 807 of the internal plate
801 et des deuxièmes orifices de fixation 815 de la pièce d’interface 812. 801 and the second fixing holes 815 of the interface part 812.
Un positionnement angulaire est choisi pour la console 7 en positionnant l’élément de positionnement 804 et l’élément de positionnement complémentaires 809 l’un par rapport à l’autre, ainsi qu’en positionnant chaque lumière 803 de la plaque externe 800 par rapport à un premier orifice de fixation de la plaque interne 801. An angular positioning is chosen for the console 7 by positioning the positioning element 804 and the complementary positioning element 809 relative to each other, as well as by positioning each slot 803 of the external plate 800 relative to a first fixing hole of the internal plate 801.
Dans le cas présent, le positionnement de la première denture 805 de l’élément de positionnement 804 de la plaque externe 800 par rapport à la deuxième denture 810 de l’élément de positionnement 804 de la plaque interne 801 , combiné au positionnement des lumières 803 permet de choisir une position angulaire pour la console 7. In the present case, the positioning of the first toothing 805 of the positioning element 804 of the external plate 800 with respect to the second toothing 810 of the positioning element 804 of the internal plate 801, combined with the positioning of the lights 803 allows you to choose an angular position for the console 7.
Le nombre de positions possibles de la plaque externe 800 sur la plaque interne 801 dépend de la combinaison entre la longueur de la lumière 803 et la coopération des éléments de positionnement 804 et éléments de positionnement complémentaires 809. The number of possible positions of the outer plate 800 on the inner plate 801 depends on the combination between the length of the slot 803 and the cooperation of the positioning elements 804 and complementary positioning elements 809.
Dans l’exemple représenté, la longueur, le nombre et la position des lumières 803 définissent le nombre de positions angulaires parmi celles permises par la coopération entre les éléments de positionnement 804 et les éléments de positionnement complémentaires 809. In the example represented, the length, the number and the position of the slots 803 define the number of angular positions among those permitted by the cooperation between the positioning elements 804 and the complementary positioning elements 809.
On comprend que l’orientation des dents de la première denture 805 et de la deuxième denture 810 modifie les positions angulaires possibles. En outre, plus la denture des éléments de positionnement 804 et éléments de positionnement complémentaires 809 est fine, c’est-à-dire plus le nombre de dents de la première denture 805 et de la deuxième denture 810, est grand, plus le nombre de positions angulaires possible pour la console 7 est grand. Au surplus, plus la longueur de chaque lumière 803 est importante, plus le nombre de positions angulaires de la console 7 sélectionnâmes parmi celles permises par les dentures, est grand. It is understood that the orientation of the teeth of the first toothing 805 and of the second toothing 810 modifies the possible angular positions. In addition, the finer the toothing of the positioning elements 804 and complementary positioning elements 809, that is to say the greater the number of teeth of the first toothing 805 and of the second toothing 810, the greater the number of possible angular positions for the console 7 is large. Moreover, the greater the length of each light 803, the greater the number of angular positions of the console 7 selected from among those permitted by the teeth, is large.
Une fois la position angulaire de chaque console 7 choisie, des écrous des boulons d’assemblage 9 sont serrés de sorte à fixer la plaque externe 800 sur la plaque interne 801. Once the angular position of each console 7 has been chosen, the nuts of the assembly bolts 9 are tightened so as to fix the external plate 800 to the internal plate 801.
La position angulaire des consoles 7 choisie dépend du type de châssis du véhicule, et notamment de la hauteur du châssis. The angular position of the consoles 7 chosen depends on the type of chassis of the vehicle, and in particular on the height of the chassis.
Ainsi, dans l’exemple de réalisation représenté, par la combinaison de choix de la première denture 805 et deuxième denture 810, ainsi que celle des lumières 803, les trois positions angulaires ou directions prédéterminées pour chaque console 7 peut être différente en fonction du type de châssis. Thus, in the exemplary embodiment represented, by the combination of choice of the first toothing 805 and second toothing 810, as well as that of the slots 803, the three angular positions or predetermined directions for each console 7 can be different depending on the type of chassis.
La plaque externe 800 peut être modifiée au besoin, notamment en modifiant les lumières, afin de s’adapter au type de châssis et donc les positons angulaires souhaitées. Selon une variante, il est possible de prévoir une plaque externe ayant des lumières très longues de sorte à s’adapter à tout ou presque type de châssis de véhicule, ou au contraire, les lumières peuvent être remplacées par une pluralité de trous individuels. The outer plate 800 can be modified as needed, in particular by modifying the lights, in order to adapt to the type of chassis and therefore the desired angular positions. Alternatively, it is possible to provide an outer plate having very long lights so as to adapt to almost any type of vehicle chassis, or on the contrary, the lights can be replaced by a plurality of individual holes.
Le dispositif anti-encastrement selon l’invention permet d’obtenir un dispositif prêt à l’emploi puisqu’une fois les plaques internes fixées au châssis, il suffit de venir positionner angulairement les consoles 7, puis de boulonner les plaques internes et externes entre elles. La fixation du dispositif anti encastrement sur le châssis porteur est très simple et ne nécessite pas de soudure ou de peinture. D’autres variantes non illustrées sont mentionnées ci-dessous. The anti-underrun device according to the invention makes it possible to obtain a ready-to-use device since once the internal plates have been fixed to the frame, it suffices to position the brackets 7 angularly, then to bolt the internal and external plates between they. Attaching the underrun device to the carrier frame is very simple and does not require welding or painting. Other variants not shown are mentioned below.
Le dispositif anti-encastrement peut être dépourvu de pièce d’interface, la plaque interne étant alors directement fixée sur le châssis. The underride protection device may have no interface piece, the internal plate then being fixed directly to the frame.
La pièce d’interface peut comporter plus ou moins de logements.The interface part may comprise more or fewer housings.
Le nombre de clavettes, boulons de fixation et boulons d’assemblage, et les trous et orifices correspondants, peut différer de ce qui est illustré sur les figures. La première denture peut être formée sur le contour périphérique du flasque de la plaque externe. The number of keys, fixing bolts and assembly bolts, and the corresponding holes and openings, may differ from what is shown in the figures. The first toothing can be formed on the peripheral contour of the flange of the outer plate.
La première denture, dite externe, peut être formée sur la plaque interne plutôt que sur la plaque externe ; et la deuxième denture, dite interne, peut être formée sur la plaque externe plutôt que sur la plaque interne. The first toothing, called external, can be formed on the internal plate rather than on the external plate; and the second toothing, called internal, can be formed on the external plate rather than on the internal plate.
L’élément de position et l’élément de position complémentaire peuvent être formés seulement partiellement par des dentures. Autrement dit, les dentures peuvent être ne pas s’étendre de manière circonférentielle et/ou être discontinues. Les consoles peuvent être soudées sur les plaques externes plutôt que par des pièces de fixation en prise dans des ouvertures et trous ménagés dans ces plaques. The position element and the complementary position element can be formed only partially by toothing. In other words, the teeth may not extend circumferentially and/or be discontinuous. The brackets can be welded to the outer plates rather than by fasteners engaging in apertures and holes in these plates.
Les consoles peuvent être mobiles et déployables à coulissement plutôt qu’articulées l’intermédiaire de vérins. La barre anti-encastrement peut comporter un seul et unique tronçon, ou au contraire plus de trois tronçons. The consoles can be mobile and deployable by sliding rather than articulated via cylinders. The underride bar can comprise a single and unique section, or on the contrary more than three sections.
Le dispositif anti-encastrement peut être dépourvu d’un capteur.The underride protection device may not have a sensor.
Le véhicule peut être une remorque plutôt qu’un camion, ou bien tout autre véhicule spécial par exemple de travaux publics, ou même un support quelconque sous lequel il pourrait être nécessaire d’empêcher l’encastrement. The vehicle can be a trailer rather than a truck, or any other special vehicle, for example public works, or even any support under which it might be necessary to prevent underrunning.
On rappelle plus généralement que l’invention ne se limite pas aux exemples décrits et représentés. It is recalled more generally that the invention is not limited to the examples described and represented.
