I - TITRE
Mini semi-remorque à coque autoporteuse.I - TITLE
Self-supporting mini-trailer.
2- DESCRLPTION
La présente invention concerne un interface de transport à coque autoporteuse, réalisé en aluminium aéronautique ou naval avec système d'attelage articulé sur trois-dimensions, tractable par un véhicule 4x4 pick-up sans permis poids-lourd.2- DESCRLPTION
The present invention relates to a transport interface with a self-supporting hull, made of aeronautical or naval aluminum with a hitching system articulated in three dimensions, towable by a 4x4 pick-up vehicle without a truck license.
Traditionnellement, les semi-remorques sont réalisées à partir d'un chassis et dotées d'une carrosserie métallique qui alourdissent considérablement le poids à vide de l'ensemble et pénalisent ainsi la charge utile. En outre, le système d'attelage fixe subit de fortes contraintes mécaniques. Du fait du poids important de l'ensemble, la semi-remorque doit être tractée par un véhicule exclusivement réservé à cet usage et nécessite que le chauffeur détienne le permis poidslourd. Traditionally, semi-trailers are made from a chassis and fitted with a metal body which considerably increases the unladen weight of the assembly and thus penalizes the payload. In addition, the fixed coupling system is subjected to high mechanical stresses. Due to the significant weight of the assembly, the semi-trailer must be towed by a vehicle exclusively reserved for this use and requires that the driver hold the truck license.
Le système de construction, selon l'invention, permet de remédier à ces inconvénients. C'est un interface de transport qui permet d'optimiser la charge utile sans avoir besoin du permis poidslourd. The construction system according to the invention overcomes these drawbacks. It is a transport interface that optimizes the payload without the need for a truck license.
n comporte en effet, selon une première caractéristique, une coque autoporteuse: le plancher est réalisé en alvéolé nid d'abeille et les panneaux formant carrosserie sont en sandwich mousse et aluminium aéronautique ou naval. Le nez de l'interface est réalisé en fibre de carbonne. n indeed has, according to a first characteristic, a self-supporting shell: the floor is made of honeycomb honeycomb and the panels forming the body are made of foam sandwich and aeronautical or naval aluminum. The interface nose is made of carbon fiber.
L'ensemble ainsi réalisé réduit considérablement le poids à vide tout en conservant la rigidité et la résistance d'une carrosserie traditionnelle basée sur un chassis classique.The assembly thus produced considerably reduces the curb weight while retaining the rigidity and strength of a traditional bodywork based on a conventional chassis.
Le système de construction, selon l'invention, comporte également, selon une seconde caractéristique, un système d'attelage de type sellette et doté d'une articulation sur trois dimensions. il s'agit d'une rotule incorporée permettant de supprimer les contraintes mécaniques de torsion de l'attelage par rapport au véhicule tracteur. Cette caractéristique supprime les contraintes sur le col-de-cygne et autorise une charge utile de l'ensemble routier jusqu'à quatre tonnes, suivant le principe des reports de charges. The construction system according to the invention also comprises, according to a second characteristic, a coupling system of the fifth wheel type and provided with a three-dimensional articulation. it is an incorporated ball joint which eliminates the mechanical torsional stresses of the coupling relative to the towing vehicle. This feature removes the constraints on the gooseneck and allows a payload of the road unit up to four tonnes, according to the principle of load carryovers.
L'ensemble de ces caractéristiques est indissociable. Le problème de la limitation de la charge utile étant résolu conjointement par l'allègement de l'ensemble et par le principe des reports de charge. All of these characteristics are inseparable. The problem of limiting the payload being resolved jointly by reducing the weight of the assembly and by the principle of load deferrals.
Selon des modes particuliers de réalisation: - les panneaux sandwich formant carrosserie peuvent être cintrés à volonté. According to particular embodiments: - the sandwich panels forming the body can be bent as desired.
- la partie avant, réalisée en fibre de carbonne est de forme bi-elliptique sur deux plans perpendiculaires pouvant varier suivant les bases de un mètre à trois mètres et suivant la hauteur de un mètre à six mètres. Les ellipses sont utilisées complètes ou partielles.- the front part, made of carbon fiber is bi-elliptical in shape on two perpendicular planes which can vary according to the bases from one meter to three meters and according to the height from one meter to six meters. Ellipses are used complete or partial.
- les ouvertures latérales, avant et arrières telles que rampes, fenetres, portes, ou autres peuvent être de dimensions variables suivant l'utilisation finale. Chaque ouverture est réalisée sur-mesures.- the lateral, front and rear openings such as ramps, windows, doors, or others can be of variable dimensions depending on the end use. Each opening is made to measure.
- L'ensemble peut être, suivant les cas, doté d'essieux traditionnels ou d'une suspension pneumatique à roues indépendantes.- The assembly can be, as the case may be, fitted with traditional axles or an air suspension with independent wheels.
- la mini seini-remorque peut être de longueur variable, jusqu'à 15 mètres.- the mini seini-trailer can be of variable length, up to 15 meters.
Les dessins annexés illustrent l'invention: - la figure 1 représente le concept de transport selon l'invention, vu de trois-quart arrière. The accompanying drawings illustrate the invention: - Figure 1 shows the concept of transport according to the invention, seen from three-quarter rear.
- la figure 2 représente le dispositif d'articulation avec rotule selon l'invention, en position ouverte.- Figure 2 shows the articulation device with ball joint according to the invention, in the open position.
- la figure 3 représente le dispositif d'articulation avec rotule, selon l'invention, en position fermée.- Figure 3 shows the hinge device with ball joint, according to the invention, in the closed position.
a / Dans la forme de réalisation, selon la figure 1, la partie formant carrosserie est réalisée à l'aide de panneaux sandwich cintrés selon une technique spécifique. Ces panneaux sont faits d'une mousse à haut pouvoir isolant doublée sur chaque face, d'une peau aluminium aéronautique ou naval.a / In the embodiment, according to FIG. 1, the body-forming part is produced using bent sandwich panels according to a specific technique. These panels are made of a high insulating foam lined on each side, of an aeronautical or naval aluminum skin.
b / Dans la forme de réalisation, selon la figure 1, le plancher porteur intégré à l'ensemble formant carrosserie est réalisé en alvéolé nid d'abeille.b / In the embodiment, according to FIG. 1, the load-bearing floor integrated into the bodywork assembly is made of honeycomb honeycomb.
c / Dans la forme de réalisation, selon la figure 1, le nez de l'ensemble peut-être réalisé en fibre de carbonne NOMEX (rnarque déposée) par moulage, selon une technique spécifique. c / In the embodiment, according to FIG. 1, the nose of the assembly may be made of NOMEX carbon fiber (registered trademark) by molding, according to a specific technique.
d / Dans la forme de réalisation, selon les figures 2 et 3, la partie formant attelage est réalisée à partir d'une sellette à laquelle est intégrée une articulation sur trois dimensions.d / In the embodiment, according to FIGS. 2 and 3, the coupling part is produced from a harness in which a three-dimensional articulation is integrated.
A titre d'exernple, non limitatif; la semi-remorque peut avoir des dimensions de l'ordre de 2.50 mètres pour la largeur, 2.40 mètres pour la hauteur intérieure et 15 mètres pour la longueur.By way of example, not limiting; the semi-trailer can have dimensions of the order of 2.50 meters for the width, 2.40 meters for the interior height and 15 meters for the length.
Le concept de réalisation, selon l'invention, est particulièrement destiné à apporter une solution dans le domaine du transport applicable à tout public. L'ensemble routier autorise une charge utile jusqu'à 4 tonnes, sans permis poids-lourd, suivant le principe des reports de charge. The concept of embodiment, according to the invention, is particularly intended to provide a solution in the field of transport applicable to all audiences. The road combination allows a payload of up to 4 tonnes, without a truck license, according to the principle of load transfer.
