Description

VEHICULE AUTOMOBILE PRESENTANT UNE NOUVELLE IMPLANTATION DE MOTOR VEHICLE HAVING A NEW IMPLANTATION OF
SON MODULE AEROTHERMIQUE.ITS AEROTHERMAL MODULE.
[0001] La présente invention concerne un véhicule automobile, qui présente une nouvelle implantation de son module aérothermique. Elle concerne également un nouveau procédé de montage sur un véhicule automobile d'un module aérothermique avec une telle implantation nouvelle.The present invention relates to a motor vehicle, which has a new implementation of its aerothermal module. It also relates to a new method of mounting on a motor vehicle of an aerothermal module with such a new implantation.
[0002] Par « module aérothermique », on entend, dans la suite du présent texte, un ensemble de matériels permettant le refroidissement du moteur, tels qu'un radiateur et un groupe motoventilateur (désigné aussi « GMV » dans la suite du texte), auquel peuvent s'ajouter éventuellement un condenseur, si le véhicule est équipé d'une climatisation, et un refroidisseur d'air de suralimentation, si le véhicule est à motorisation turbocompressée.By "aerothermal module" means, in the following text, a set of equipment for cooling the engine, such as a radiator and a motor fan (also referred to as "GMV" in the following text) , to which may be added a condenser, if the vehicle is equipped with an air conditioning, and a charge air cooler, if the vehicle is turbocharged.
[0003] Ce module aérothermique est situé, de manière classique, à l'avant du bloc avant du véhicule, entre la poutre de choc et le groupe motopropulseur (désigné aussi « GMP » dans la suite du texte), selon une implantation dite « en façade », les différents éléments du module aérothermique étant disposés sensiblement verticalement les uns contre les autres.This aerothermal module is located, conventionally, in front of the front block of the vehicle, between the shock beam and the powertrain (also referred to as "GMP" in the rest of the text), according to a layout called " in facade ", the various elements of the aerothermal module being arranged substantially vertically against each other.
[ooo4] Cette implantation en façade présente l'inconvénient de nécessiter une longueur de structure porteuse relativement importante entre le centre de la roue avant et l'extrémité avant du véhicule. Cette longueur importante a pour conséquence, d'une part, d'augmenter la longueur hors tout du véhicule et, d'autre part, d'augmenter le porte-à-faux avant. Une longueur trop importante de ce porte-à- faux avant préjudicie au « style », à l'aérodynamique, à la masse et au coût du véhicule, au rayon de braquage entre murs, et réduit l'angle d'attaque, c'est-à-dire l'inclinaison maximale de la pente ascendante que peut aborder le véhicule sans endommager le bas de sa caisse.[Ooo4] This front layout has the disadvantage of requiring a relatively large carrier structure length between the center of the front wheel and the front end of the vehicle. This length has the consequence, on the one hand, to increase the overall length of the vehicle and, on the other hand, to increase the front overhang. Too long a length of this front overhang prejudices the "style", the aerodynamics, the mass and the cost of the vehicle, the turning circle between walls, and reduces the angle of attack, it that is to say the maximum inclination of the ascending slope that can approach the vehicle without damaging the bottom of the body.
[oooδ] Pour surmonter une ou plusieurs de ces difficultés, on a déjà modifié sensiblement l'implantation du module aérothermique, ou de l'un au moins des éléments qui le constituent. [oooθ] On connaît, par exemple, selon le document FR 2 217 201 , un véhicule automobile dans lequel le radiateur est disposé transversalement au sens de la marche et est monté incliné dans le véhicule, de telle sorte que le plan d'inclinaison du radiateur soit orienté obliquement du haut vers le bas dans le sens de la marche. Au-dessus du radiateur est prévue une roue de secours, laquelle est recouverte par la paroi du capot.[oooδ] To overcome one or more of these difficulties, it has already substantially changed the implementation of the aerothermal module, or at least one of the elements that constitute it. [Oooθ] is known, for example, according to the document FR 2 217 201, a motor vehicle in which the radiator is disposed transversely to the direction of travel and is mounted inclined in the vehicle, so that the plane of inclination of the radiator is oriented obliquely from top to bottom in the direction of travel. Above the radiator is a spare wheel, which is covered by the hood wall.
[0007] A titre d'exemple également, le document US 2006/0103127 A1 décrit un véhicule automobile, qui comporte deux longerons et une structure fixée sur les longerons de façon à définir un châssis de véhicule. Une suspension avant indépendante est fixée à la structure. Un radiateur, un moteur et un dispositif de pare-chocs sont fixés à des pattes de fixation de la structure. Le radiateur ne présente pas une implantation en façade, mais est situé dans un plan incliné par rapport au sol et se déploie en grande partie au-dessus de la roue avant du véhicule. Lorsque la structure est fixée aux longerons, le moteur est situé sous les sièges dans la cabine et derrière la suspension avant. Un capot du véhicule peut être incliné par rapport au plan du sol, dans un plan sensiblement parallèle au plan du radiateur, de manière à améliorer la forme aérodynamique de la cabine et la visibilité du conducteur.By way of example also, the document US 2006/0103127 A1 describes a motor vehicle, which comprises two longitudinal members and a structure fixed on the side members so as to define a vehicle chassis. An independent front suspension is attached to the structure. A radiator, a motor and a bumper device are attached to the fastening tabs of the structure. The radiator does not have a front layout, but is located in a plane inclined to the ground and unfolds largely above the front wheel of the vehicle. When the structure is attached to the side members, the engine is located under the seats in the cab and behind the front suspension. A hood of the vehicle can be inclined relative to the ground plane, in a plane substantially parallel to the plane of the radiator, so as to improve the aerodynamic shape of the cabin and the visibility of the driver.
[oooδ] Le but de la présente invention est de concevoir une nouvelle implantation du module aérothermique sur un véhicule automobile, qui permette d'obvier aux inconvénients précités de l'implantation en façade et des implantations légèrement différentes, connues de l'art antérieur, et rappelées ci-dessus.The object of the present invention is to design a new implantation of the aerothermal module on a motor vehicle, which overcomes the aforementioned drawbacks of the front layout and slightly different implantations, known from the prior art, and recalled above.
[0009] Un autre but de la présente invention est de permettre, grâce à cette nouvelle implantation du module aérothermique, une nouvelle architecture de bloc avant de véhicule automobile, qui permette de rendre optimal le porte-à-faux avant technique et la longueur hors tout du véhicule.Another object of the present invention is to enable, thanks to this new implementation of the aerothermal module, a new architecture of the front block of a motor vehicle, which makes it possible to optimize the front overhang technical and the length off all of the vehicle.
[ooio] Enfin, c'est également un but de la présente invention de réaliser un tel changement d'implantation du module aérothermique, qui soit simple, économique, et facilite la maintenance du module.[ooio] Finally, it is also an object of the present invention to achieve such a change of layout of the aerothermal module, which is simple, economical, and facilitates the maintenance of the module.
[0011] Pour parvenir à ces buts, la présente invention a pour objet un véhicule automobile, qui comprend un module aérothermique constitué au moins par du matériel de refroidissement du moteur comportant un radiateur et un groupe motoventilateur, et ce module aérothermique est placé au dessus du groupe motopropulseur du véhicule, dans l'espace compris entre la surface fictive dite « de capot technique » et la surface du groupe moto-propulseur augmenté de son débattement, de manière à réduire la distance entre le groupe motopropulseur et la poutre de choc à l'avant du véhicule et, en conséquence, à réduire le porte-à-faux avant du bloc avant du véhicule.To achieve these objects, the present invention relates to a motor vehicle, which comprises an aerothermal module consisting at least of engine cooling equipment comprising a radiator and a fan unit, and this aerothermal module is placed above the powertrain of the vehicle, in the space between the dummy surface called "technical hood" and the surface of the powertrain increased travel, so as to reduce the distance between the powertrain and the impact beam at the front of the vehicle and, consequently, to reduce the front overhang of the front block of the vehicle.
[0012] Selon une variante de réalisation de l'invention, le module aérothermique peut être constitué, de plus, par un condenseur du système de climatisation du véhicule.According to an alternative embodiment of the invention, the aerothermal module may be constituted, in addition, by a condenser of the air conditioning system of the vehicle.
[0013] Selon une autre variante de réalisation de l'invention, le module aérothermique peut aussi comprendre un refroidisseur d'air de suralimentation, s'il s'agit d'un véhicule à motorisation turbocompressée.According to another embodiment of the invention, the aerothermal module may also include a charge air cooler, if it is a turbocharged engine.
[0014] Selon un mode préféré de réalisation de l'invention, le module aérothermique est implanté sur un cadre qui est monté articulé sur le véhicule, entre une position normale de fonctionnement et une position relevée dite « après-vente » dans laquelle peuvent être plus facilement réalisées les opérations courantes d'entretien du module sans avoir à démonter ce dernier ou ouvrir les différents circuits dudit module.According to a preferred embodiment of the invention, the aerothermal module is located on a frame which is mounted articulated on the vehicle, between a normal operating position and a raised position called "after-sales" in which can be more easily performed the routine maintenance of the module without having to dismount it or open the various circuits of said module.
[0015] Ce cadre, désigné aussi « cadre après-vente », peut être articulé autour d'un axe sensiblement horizontal et s'étendant selon une direction transversale du véhicule.This frame, also called "after-sales frame", can be articulated about a substantially horizontal axis and extending in a transverse direction of the vehicle.
[0016] En variante, le cadre après-vente peut être articulé autour d'un axe contenu dans un plan vertical longitudinal du véhicule.Alternatively, the after-sales frame can be articulated around an axis contained in a longitudinal vertical plane of the vehicle.
[0017] Une gaine d'alimentation en air frais du matériel de refroidissement du moteur peut être avantageusement réalisée en matière souple, et être partiellement implantée, grâce à sa souplesse, au-dessus du capot technique.A fresh air supply duct of the engine cooling material can be advantageously made of flexible material, and be partially implemented, thanks to its flexibility, above the technical hood.
[0018] De préférence, des mousses permettent d'assurer une bonne étanchéité entre la gaine d'alimentation en air frais et le matériel de refroidissement du moteur. [0019] S'il s'agit d'un véhicule à motorisation turbocompressée, le refroidisseur d'air de suralimentation au dessus du GMP peut être implanté à côté du condenseur et du matériel de refroidissement du moteur (« en mosaïque »), ou bien dans l'empilage avec le condenseur et le matériel de refroidissement du moteur. [0020] La présente invention a également pour objet un procédé de montage d'un module aérothermique de véhicule automobile, ledit véhicule automobile présentant un module aérothermique monté sur un cadre articulé tel que celui décrit ci-dessus dans ses grandes lignes, et ce nouveau procédé comporte les étapes suivantes, prises en combinaison : • préparation du cadre sur lequel est implanté le module aérothermique, à savoir montage sur ledit cadre des éléments qui constituent le module aérothermique et des tuyaux d'entrée et de sortie desdits éléments,Preferably, foams make it possible to ensure a good seal between the fresh air supply duct and the engine cooling equipment. If it is a turbocharged engine, the charge air cooler above the GMP can be installed next to the condenser and engine cooling equipment ("mosaic"), or well in the stack with the condenser and the engine cooling equipment. The present invention also relates to a method of mounting an aerothermal module of a motor vehicle, said motor vehicle having an aerothermal module mounted on an articulated frame such as that described above in outline, and this new method comprises the following steps, taken in combination: • preparation of the frame on which is implanted the aerothermal module, namely mounting on said frame elements that constitute the aerothermal module and inlet and outlet pipes of said elements,
• raccordement, après coiffage du GMP, des liaisons GMP/caisse, notamment des tuyaux d'entrée et de sortie aérotherme, • fixation du cadre sur la caisse du véhicule,• connection, after capping of the GMP, GMP connections / box, including inlet and outlet heater hoses, • fixing the frame on the vehicle body,
• raccordement des tuyaux et faisceaux des éléments du module aérothermique sur les différents éléments du véhicule reliés audit module aérothermique.Connecting the pipes and bundles of the elements of the aerothermal module to the various elements of the vehicle connected to said aerothermal module.
[0021] Les tuyaux et les faisceaux des éléments du module aérothermique, qui sont raccordés sur les différents éléments du véhicule reliés au module aérothermique, peuvent comprendre les tuyaux d'entrée et de sortie du radiateur sur le moteur du véhicule, le tuyau de dégazage du radiateur sur la boîte de dégazage, les tuyaux de réfrigération sur le condenseur, le faisceau du groupe motoventilateur ainsi que les tuyaux d'entrée et de sortie du refroidisseur d'air de suralimentation.The pipes and bundles of the elements of the aerothermal module, which are connected to the various elements of the vehicle connected to the aerothermal module, may include the inlet and outlet pipes of the radiator on the engine of the vehicle, the degassing pipe the radiator on the degassing box, the refrigeration pipes on the condenser, the fan assembly harness and the inlet and outlet hoses of the charge air cooler.
[0022] D'autres buts, avantages et caractéristiques de l'invention apparaîtront dans la description qui suit d'un mode de réalisation préféré, non limitatif de l'objet et de la portée de la présente demande de brevet, accompagnée de dessins dans lesquels :Other objects, advantages and features of the invention will appear in the following description of a preferred embodiment, not limiting the object and scope of the present patent application, accompanied by drawings in which :

Ce module 1 est situé au-dessus du GMP, de référence générale 8, dans un espace compris entre le capot 10 du véhicule et le GMP 8, plus précisément dans l'espace compris entre la surface fictive dite « de capot technique », représentée par la ligne 9 sur la figure 1 , et la surface du GMP augmenté de son débattement, dite surface du « GMP débattu », représentée par la ligne 1 1 sur la figure 1.Referring to the drawing of Figure 1, there is shown schematically, in longitudinal section, the new implantation according to the present invention of the various constituent elements of a motor vehicle aerothermal module, general reference 1. The aerothermal module 1 comprises, on the one hand, equipment for cooling the air of the engine, such as a radiator 2 and a fan motor 3, of the suction or blowing type, single speed or twin speed, and, on the other hand, the condenser 4 of an air conditioning system of the vehicle. This module 1 is located above the GMP, general reference 8, in a space between the hood 10 of the vehicle and the GMP 8, more precisely in the space between the fictitious surface called "technical hood", shown by line 9 in Figure 1, and the surface of the GMP increased its deflection, said surface of the "GMP discussed", represented by the line 1 1 in Figure 1.
[0024] Par « capot technique », on entend, de manière classique, la surface fictive, située sous la doublure du capot, qui délimite avec cette dernière une zone d'exclusion, dans laquelle est exclue toute implantation d'un composant rigide, de manière à tenir compte des conséquences possibles d'un choc piéton. Le « capot technique » 9 constitue la limite de conception suffisamment éloignée du capot pour être compatible avec la réglementation relative au choc piéton.By "technical hood" is meant, in a conventional manner, the dummy surface, located under the lining of the hood, which delimits with the latter an exclusion zone, in which is excluded any implantation of a rigid component, in order to take into account the possible consequences of a pedestrian impact. The "technical hood" 9 is the design limit sufficiently far from the hood to be compatible with the pedestrian impact regulation.
[0025] Par « GMP débattu » 1 1 , on entend la surface externe du GMP augmenté de son espace de débattement, le débattement étant dû principalement aux sollicitations de la route.By "GMP discussed" January 1 means the outer surface of the GMP increased its clearance space, the deflection being due mainly to the demands of the road.
[0026] La nouvelle implantation du module aérothermique 1 au-dessus du GMP 8 permet de réduire substantiellement la distance entre le GMP 8 et la poutre de choc, référencée 7 sur les figures, à l'extrémité avant du véhicule et, en conséquence, permet de réduire le porte-à-faux avant du véhicule, c'est-à-dire la distance entre l'extrémité avant du véhicule et le centre de la roue avant (non représentée).The new implementation of the aerothermal module 1 above the GMP 8 substantially reduces the distance between the GMP 8 and the shock beam, referenced 7 in the figures, at the front end of the vehicle and, accordingly, can reduce the front overhang of the vehicle, that is to say the distance between the front end of the vehicle and the center of the front wheel (not shown).
[0027] Ainsi, selon un essai comparatif établi par la Demanderesse, un porte-à-faux avant technique (c'est-à-dire hors absorbeur piéton et galbe du style) de 840 mm environ sur un véhicule à module aérothermique implanté en façade, de façon classique, a pu être réduit de 230 mm environ grâce à l'implantation nouvelle, au dessus du GMP, qui fait l'objet de la présente invention. Cette réduction est illustrée par la distance G (figure 3) entre la poutre de choc 7' d'une implantation en façade du module selon l'art antérieur et la poutre de choc 7 de l'implantation nouvelle du module selon la présente invention.Thus, according to a comparative test established by the Applicant, a technical front overhang (that is to say excluding pedestrian absorber and curve of the style) of about 840 mm on a vehicle with aerothermal module implanted in frontage, in a conventional manner, could be reduced by about 230 mm thanks to the new implantation, above the GMP, which is the subject of the present invention. This reduction is illustrated by the distance G (FIG. 3) between the shock beam 7 'of an implantation on the front of the module according to the prior art and the shock beam 7 of the new implantation of the module according to the present invention.
[0028] Comme représenté sur les figures 2 et 3 en particulier, le module aérothermique 1 , représenté avec le condenseur 4 et le radiateur 2, est monté sur un cadre 12, sensiblement rectangulaire, fixé sur une partie de véhicule référencée 6.As shown in Figures 2 and 3 in particular, the aerothermal module 1, shown with the condenser 4 and the radiator 2, is mounted on a frame 12, substantially rectangular, fixed on a vehicle part referenced 6.
[0029] Le cadre 12 est articulé, par l'intermédiaire de charnières 12A, autour d'un axe référencé X, qui peut être, par exemple, un axe sensiblement horizontal et transversal.The frame 12 is articulated, by means of hinges 12A, about an axis referenced X, which may be, for example, a substantially horizontal axis and transverse.
[0030] En variante, le cadre 12 peut être articulé autour d'un axe contenu dans un plan vertical longitudinal du véhicule.Alternatively, the frame 12 may be articulated about an axis contained in a longitudinal vertical plane of the vehicle.
[0031] Comme on peut le voir sur la figure 4, la liaison articulée du cadre 12 permet de déplacer ce dernier entre une position normale de fonctionnement (référencée position A) et une position relevée dite « après-vente » (référencée B) dans laquelle peuvent être plus facilement réalisées les opérations courantes d'entretien du module sans avoir à démonter ce dernier ou ouvrir les différents circuits dudit module.As can be seen in Figure 4, the articulated connection of the frame 12 can move the latter between a normal operating position (referenced position A) and a raised position called "after-sales" (referenced B) in which can be more easily performed the routine maintenance of the module without having to dismount it or open the various circuits of said module.
[0032] Les conduits d'eau, de fluide réfrigérant et de dégazage sont adaptés et permettent de mettre le module aérothermique 1 en position « après-vente » (position B de la figure 4).The water ducts, coolant and degassing are adapted and allow to put the aerothermal module 1 in "after-sales" position (position B of Figure 4).
[0033] L'inclinaison du cadre 12 par rapport à la verticale est minimale, de façon à ne pas pénaliser la performance des échangeurs. Le matériel de refroidissement, constitué d'éléments « durs », est tangent au capot technique 9 construit à partir du capot de style 10, lui-même en cohérence avec le style et le critère de visibilité basse.The inclination of the frame 12 relative to the vertical is minimal, so as not to penalize the performance of the exchangers. The cooling equipment, consisting of "hard" elements, is tangent to the technical hood 9 built from the style hood 10, itself consistent with the style and the criterion of low visibility.
[0034] Une gaine 16 d'alimentation en air frais (figure 1 ), fixée sur la face avant, permet d'alimenter le matériel de refroidissement avec les vitesses d'air qui conviennent. Cette gaine 16 est réalisée en matière souple et, grâce à cette souplesse, peut être partiellement implantée au-dessus du capot technique 9.A sheath 16 fresh air supply (Figure 1), fixed on the front, allows to feed the cooling equipment with the appropriate air velocities. This sheath 16 is made of flexible material and, thanks to this flexibility, can be partially installed above the technical hood 9.
[0035] Des mousses (non représentées) permettent d'assurer une bonne étanchéité entre la gaine 16 d'alimentation en air frais et le radiateur 2 et/ou le condenseur 4.Foams (not shown) provide a good seal between the duct 16 for supplying fresh air and the radiator 2 and / or the condenser 4.
[0036] Selon une variante de réalisation non représentée, le véhicule automobile est un véhicule à motorisation turbocompressée et le module aérothermique 1 , placé au dessus du GMP, comprend, de plus, un refroidisseur d'air de suralimentation, qui est implanté « en mosaïque » à côté du condenseur 4 et du matériel de refroidissementAccording to an alternative embodiment not shown, the motor vehicle is a turbocharged engine and the aerothermal module 1, placed above the GMP, further comprises a supercharging air cooler, which is implanted "in mosaic "next to condenser 4 and cooling equipment
2, 3 du moteur. En variante, le refroidisseur d'air de suralimentation peut être implanté « de manière surfacique » dans l'empilage avec le condenseur 4 et le matériel de refroidissement 2, 3 du moteur.2, 3 of the engine. Alternatively, the charge air cooler can be implanted "surface" in the stack with the condenser 4 and the cooling equipment 2, 3 of the engine.
[0037] La présente invention concerne aussi un procédé de montage d'un module aérothermique 1 dont l'implantation est celle décrite ci-dessus.The present invention also relates to a method of mounting an aerothermal module 1 whose implantation is that described above.
[0038] Ce procédé permet le raccordement des tuyaux d'entrée et de sortie du module aérothermique 1 , dont les interfaces sont généralement implantées dans la zone centrale du tablier du véhicule.This method allows the connection of the inlet and outlet pipes of the aerothermal module 1, whose interfaces are generally located in the central area of the apron of the vehicle.
[0039] II comporte les étapes suivantes :It comprises the following steps:
• préparation du cadre « après-vente » 12, sur lequel est implanté le module aérothermique 1 , à savoir montage du condenseur 4, du radiateur 2, du GMV 3, des tuyaux d'entrée et de sortie du radiateur 2, du tuyau de dégazage, et éventuellement du refroidisseur d'air de suralimentation,• preparation of the "after-sales" framework 12, on which is implanted the aerothermal module 1, namely assembly of the condenser 4, the radiator 2, the GMV 3, the inlet and outlet pipes of the radiator 2, the pipe of degassing, and possibly the charge air cooler,
• montage du cadre 12 ainsi préparé en position de « coiffage » du groupe motopropulseur 8,Mounting the frame 12 thus prepared in the "styling" position of the powertrain 8,
• raccordement des tuyaux d'entrée et de sortie des éléments qui constituent le module aérothermique 1 , • fixation du cadre 12 sur la caisse du véhicule, et • raccordement des tuyaux et faisceaux des éléments du module aérothermique 1 sur les différents éléments du véhicule reliés audit module aérothermique.• connection of the inlet and outlet pipes of the elements that constitute the aerothermal module 1, • attachment of the frame 12 to the vehicle body, and Connecting the pipes and bundles of the elements of the aerothermal module 1 to the various elements of the vehicle connected to said aerothermal module.
[0040] Les tuyaux et faisceaux des éléments du module aérothermique 1 , qui sont raccordés sur les différents éléments du véhicule reliés au module aérothermique 1 , comprennent les tuyaux d'entrée et de sortie du radiateur 2 sur le moteur du véhicule, le tuyau de dégazage du radiateur 2 sur la boîte de dégazage, les tuyaux de réfrigération sur le condenseur 4, et le faisceau du GMV 3.The pipes and bundles of the elements of the aerothermal module 1, which are connected to the various elements of the vehicle connected to the aerothermal module 1, include the inlet and outlet pipes of the radiator 2 on the engine of the vehicle, the pipe of degassing of the radiator 2 on the degassing box, the refrigeration pipes on the condenser 4, and the beam of the GMV 3.
[0041] L'implantation décrite ci-dessus d'un module aérothermique de véhicule automobile présente l'avantage de permettre un gain en rendement d'architecture du bloc avant du véhicule. Ce rendement se traduit essentiellement par une forte réduction de la distance entre la poutre de choc 7 et le GMP 8, par conséquent une forte réduction du porte-à-faux avant technique du véhicule. Ce porte-à-faux avant technique peut être réduit, comme mentionné précédemment, de 230 mm environ par exemple avec la nouvelle implantation du module 1 au dessus du GMP par rapport à l'implantation classique en façade. Un tel gain en longueur permet alors :The implementation described above of a motor vehicle aerothermal module has the advantage of allowing a gain in architecture performance of the front block of the vehicle. This yield essentially results in a sharp reduction in the distance between the impact beam 7 and the GMP 8, therefore a sharp reduction in the technical front overhang of the vehicle. This front overhang technical front can be reduced, as mentioned above, about 230 mm for example with the new implementation of the module 1 above the GMP compared to the conventional layout in front. Such a gain in length then allows:
• soit, à longueur de véhicule égale, d'optimiser le volume de chargement du véhicule d'environ 500 litres (représentant une augmentation de 10% à 15% de ce volume), en avançant le poste de conduite et le GMP,• Or, for the same vehicle length, optimize the vehicle's loading volume by approximately 500 liters (representing a 10% to 15% increase in this volume), by advancing the driving position and the GMP,
• soit d'optimiser le porte-à-faux et la longueur hors tout du véhicule, et donc le rayon de braquage entre murs, le style et l'aérodynamique du véhicule,• optimize the overhang and the overall length of the vehicle, and thus the turning circle between walls, the style and the aerodynamics of the vehicle,
[0042] Bien entendu, la présente invention n'est pas limitée au mode de réalisation décrit et représenté ci-dessus à titre d'exemple ; d'autres modes de réalisation peuvent être conçus par l'homme de métier sans sortir du cadre et de la portée de la présente invention. Of course, the present invention is not limited to the embodiment described and shown above by way of example; other embodiments may be devised by those skilled in the art without departing from the scope and scope of the present invention.
