Description
Titre de l'invention : CHÂSSIS MODULAIRE DE VÉHICULE AUTOMOBILE Title of the invention: MODULAR MOTOR VEHICLE CHASSIS
La présente invention se rapporte à un châssis modulaire de véhicule automobile. The present invention relates to a modular motor vehicle chassis.
L’invention appartient au domaine des châssis de véhicules automobiles et trouve à s’appliquer à tout moyen de transport roulant. The invention belongs to the field of motor vehicle chassis and is applicable to any rolling means of transport.
Actuellement, une grande diversité de plateformes ou châssis, ayant des architectures et des dimensions différentes, est nécessaire pour réaliser différents types de véhicules automobiles, ayant différents groupes motopropulseurs et différentes liaisons au sol. Currently, a wide variety of platforms or chassis, having different architectures and dimensions, is necessary to produce different types of motor vehicles, having different powertrains and different ground connections.
Afin de réduire les coûts, il est connu de prévoir une plateforme modulaire, comportant des éléments communs à plusieurs types de véhicules et permettant donc de construire plusieurs types de véhicules à partir d’une même plateforme.In order to reduce costs, it is known to provide a modular platform, comprising elements common to several types of vehicles and therefore making it possible to build several types of vehicles from the same platform.
Néanmoins, les éléments composant les plateformes actuelles sont souvent réalisés en tôle emboutie dans des matériaux présentant une masse élevée. En outre, la forme de nombreux éléments composant les plateformes actuelles diffère selon le type de véhicule à réaliser, ce qui maintient un niveau de diversité et donc de coût de fabrication élevé. However, the elements making up current platforms are often made of pressed sheet metal in materials with a high mass. In addition, the shape of many elements making up current platforms differs depending on the type of vehicle to be produced, which maintains a level of diversity and therefore high manufacturing costs.
La présente invention a pour but de remédier aux inconvénients précités de l’art antérieur. The present invention aims to remedy the aforementioned drawbacks of the prior art.
Dans ce but, la présente invention propose un châssis de véhicule automobile, comportant un plancher central, une partie avant fixée à une première extrémité du plancher central et une partie arrière fixée à une seconde extrémité du plancher central, remarquable en ce que : le plancher central comporte quatre éléments d’angle invariants quel que soit le type de véhicule à réaliser ; les quatre éléments d’angle sont en aluminium, comprennent deux éléments d’angle avant et deux éléments d’angle arrière et sont reliés, d’une part, par une paire de profilés longitudinaux en aluminium reliant chacun un élément d’angle avant et l’élément d’angle arrière qui lui fait face et d’autre part, par une paire de profilés transversaux avant et arrière en aluminium, le profilé transversal avant
reliant les éléments d’angle avant et le profilé transversal arrière reliant les éléments d’angle arrière, la longueur des profilés longitudinaux et des profilés transversaux variant selon le type de véhicule à réaliser ; la partie avant comporte une paire de longerons avant reliant la partie avant au plancher central et au moins une traverse avant s’étendant orthogonalement entre les longerons avant et la partie arrière comporte une paire de longerons arrière et au moins une traverse arrière s’étendant orthogonalement entre les longerons arrière, la longueur des longerons avant et arrière et des traverses avant et arrière variant selon le type de véhicule à réaliser. For this purpose, the present invention proposes a motor vehicle chassis, comprising a central floor, a front part fixed to a first end of the central floor and a rear part fixed to a second end of the central floor, remarkable in that: the floor central has four invariant corner elements whatever the type of vehicle to be produced; the four corner elements are made of aluminum, comprise two front corner elements and two rear corner elements and are connected, on the one hand, by a pair of longitudinal aluminum profiles each connecting a front corner element and the rear corner element which faces it and on the other hand, by a pair of front and rear transverse aluminum profiles, the front transverse profile connecting the front corner elements and the rear transverse profile connecting the rear corner elements, the length of the longitudinal profiles and the transverse profiles varying depending on the type of vehicle to be produced; the front part comprises a pair of front side members connecting the front part to the central floor and at least one front cross member extending orthogonally between the front side members and the rear part comprises a pair of rear side members and at least one rear cross member extending orthogonally between the rear spars, the length of the front and rear spars and the front and rear crossmembers varying depending on the type of vehicle to be produced.
Ainsi, non seulement le caractère modulaire du châssis conforme à la présente invention permet d’utiliser ce châssis pour réaliser divers types de véhicules, moyennant de simples modifications de ses dimensions, mais en outre, l’utilisation d’éléments d’angle invariants permet de réduire de façon significative la diversité et donc les coûts et les délais de fabrication. Par ailleurs, l’utilisation d’éléments d’angle en aluminium et de profilés en aluminium permet d’alléger les véhicules. Le même châssis permet donc de réaliser plus rapidement des véhicules plus légers ayant différents groupes motopropulseurs, différentes liaisons au sol et différentes esthétiques, tout en étant moins coûteux. Thus, not only does the modular nature of the chassis according to the present invention make it possible to use this chassis to produce various types of vehicles, with simple modifications of its dimensions, but also, the use of invariant corner elements allows to significantly reduce diversity and therefore costs and manufacturing times. Furthermore, the use of aluminum corner elements and aluminum profiles makes vehicles lighter. The same chassis therefore makes it possible to produce lighter vehicles more quickly with different powertrains, different ground connections and different aesthetics, while being less expensive.
Dans un mode particulier de réalisation, les quatre éléments d’angle sont des blocs issus de fonderie en aluminium. In a particular embodiment, the four corner elements are blocks made from aluminum casting.
Cela offre un bon compromis entre robustesse et légèreté et cela apporte une longévité optimale à ces pièces. This offers a good compromise between robustness and lightness and provides optimal longevity to these parts.
Dans un mode particulier de réalisation, la paire de profilés longitudinaux et la paire de profilés transversaux sont issues d’une filière d’extrusion d’aluminium.In a particular embodiment, the pair of longitudinal profiles and the pair of transverse profiles come from an aluminum extrusion die.
Cela permet de décliner aisément ces pièces entre différentes dimensions, selon le type de véhicule à réaliser. This makes it easy to break down these parts into different dimensions, depending on the type of vehicle to be made.
Dans un mode particulier de réalisation, la paire de profilés longitudinaux est une paire de bavolets, le profilé transversal avant est fixé à la paire de bavolets entre les éléments d’angle avant et le profilé transversal arrière est fixé à la paire de bavolets entre les éléments d’angle arrière. In a particular embodiment, the pair of longitudinal profiles is a pair of sills, the front transverse profile is fixed to the pair of sills between the front corner elements and the rear transverse profile is fixed to the pair of sills between the rear corner elements.
Cette configuration facilite l’assemblage du véhicule.
Dans un mode particulier de réalisation, la paire de bavolets est pourvue d’un réseau de nervures internes de renforcement. This configuration facilitates vehicle assembly. In a particular embodiment, the pair of flaps is provided with a network of internal reinforcing ribs.
Ce réseau de nervures est facilement adaptable en fonction de la rigidité de la caisse souhaitée. This network of ribs is easily adaptable depending on the rigidity of the body desired.
Dans un mode particulier de réalisation, la paire de bavolets est emmanchée dans des cavités prévues sur les quatre éléments d’angle. In a particular embodiment, the pair of flaps is fitted into cavities provided on the four corner elements.
Cet assemblage est particulièrement simple à réaliser et de bonne qualité. This assembly is particularly simple to make and of good quality.
Dans un mode particulier de réalisation, la paire de bavolets est en outre fixée aux éléments d’angle par de la colle et par au moins un rivet. In a particular embodiment, the pair of flaps is also fixed to the corner elements by glue and by at least one rivet.
Cela permet d’augmenter encore la fiabilité de l’assemblage en supprimant tout jeu éventuel entre les bavolets et les éléments d’angle. This further increases the reliability of the assembly by eliminating any possible play between the flaps and the corner elements.
Dans un mode particulier de réalisation, la partie avant et la partie arrière sont fixées au plancher central par vissage et/ou boulonnage. In a particular embodiment, the front part and the rear part are fixed to the central floor by screwing and/or bolting.
L’assemblage du plancher central et des parties avant et arrière est ainsi particulièrement simple à réaliser et renforce le caractère modulaire du châssis.The assembly of the central floor and the front and rear parts is therefore particularly simple to carry out and reinforces the modular nature of the chassis.
Dans le même but que celui indiqué plus haut, la présente invention propose également un véhicule automobile, remarquable en ce qu’il comporte un châssis tel que décrit succinctement ci-dessus. For the same purpose as that indicated above, the present invention also proposes a motor vehicle, remarkable in that it comprises a chassis as briefly described above.
Dans le même but que celui indiqué plus haut, la présente invention propose également une gamme d’au moins deux types de véhicules automobiles comportant chacun un châssis tel que décrit succinctement ci-dessus, remarquable en ce que les éléments d’angle avant et arrière sont invariants entre les deux types de véhicules, tandis qu’au moins une paire de profilés choisis parmi, soit les profilés longitudinaux, soit les profilés transversaux avant et arrière, a une longueur différente pour chacun des deux types de véhicules. For the same purpose as that indicated above, the present invention also proposes a range of at least two types of motor vehicles each comprising a chassis as briefly described above, remarkable in that the front and rear corner elements are invariant between the two types of vehicles, while at least one pair of profiles chosen from either the longitudinal profiles or the front and rear transverse profiles, has a different length for each of the two types of vehicles.
Les avantages et les caractéristiques particulières du véhicule et de la gamme étant identiques à ceux du châssis, ils ne sont pas répétés ici. The advantages and particular characteristics of the vehicle and the range being identical to those of the chassis, they are not repeated here.

The four corner elements 18 comprise two front corner elements 180 symmetrical with respect to the plane XZ and two rear corner elements 182 symmetrical with respect to the plane XZ.
Les quatre éléments d’angle 18 sont en aluminium et sont typiquement constitués de blocs issus d’un procédé de fonderie en aluminium. De façon classique en matière de fonderie, ce procédé conditionne les courbes et angles de raccordement des surfaces extérieures des quatre éléments d’angle. The four corner elements 18 are made of aluminum and are typically made up of blocks resulting from an aluminum foundry process. In a classic foundry manner, this process conditions the curves and connection angles of the exterior surfaces of the four corner elements.
Les quatre éléments d’angle 18 sont reliés par une paire de profilés longitudinaux 20 s’étendant dans la direction longitudinale avant-arrière X, appelés aussi longerons latéraux et par une paire de profilés transversaux 22 avant et arrière s’étendant dans la direction transversale gauche-droite Y. Le terme « profilé » signifie que ces pièces présentent une section constante. The four corner elements 18 are connected by a pair of longitudinal profiles 20 extending in the front-rear longitudinal direction left-right Y. The term “profile” means that these parts have a constant section.
Chaque profilé de la paire de profilés longitudinaux 20 relie un élément d’angle avant 180 et l’élément d’angle arrière 182 qui lui fait face. Each profile of the pair of longitudinal profiles 20 connects a front corner element 180 and the rear corner element 182 which faces it.
Le profilé transversal 22 avant relie entre eux les deux éléments d’angle avant 180 et le profilé transversal 22 arrière relie entre eux les deux éléments d’angle arrière 182. The front transverse profile 22 connects the two front corner elements 180 together and the rear transverse profile 22 connects the two rear corner elements 182 together.
En outre, les profilés 20 et 22 sont en aluminium, par exemple en aluminium extrudé, c’est-à-dire que les profilés 20 et 22 peuvent être issus d’une filière d’extrusion d’aluminium.
Les longueurs des profilés 20 et 22 sont variables d’un type de véhicule à l’autre au sein d’une même gamme de véhicules, suivant la direction des flèches Fx et FY. In addition, the profiles 20 and 22 are made of aluminum, for example extruded aluminum, that is to say that the profiles 20 and 22 can come from an aluminum extrusion die. The lengths of the profiles 20 and 22 vary from one type of vehicle to another within the same range of vehicles, following the direction of the arrows Fx and F Y.
La paire de profilés longitudinaux 20 est par exemple une paire de bavolets. Dans ce mode de réalisation, chaque bavolet 20 relie un élément d’angle avant 180 et l’élément d’angle arrière 182 qui lui fait face. The pair of longitudinal profiles 20 is for example a pair of flaps. In this embodiment, each flap 20 connects a front corner element 180 and the rear corner element 182 which faces it.
Dans ce mode de réalisation, la paire de profilés transversaux 22 est orthogonale à la paire de bavolets 20. Le profilé transversal 22 avant est fixé à la paire de bavolets 20 entre les deux éléments d’angle avant 180 et le profilé transversal 22 arrière est fixé à la paire de bavolets 20 entre les deux éléments d’angle arrière 182. In this embodiment, the pair of transverse profiles 22 is orthogonal to the pair of flaps 20. The front transverse profile 22 is fixed to the pair of flaps 20 between the two front corner elements 180 and the rear transverse profile 22 is fixed to the pair of flaps 20 between the two rear corner elements 182.
La partie avant 14 comporte une paire de longerons avant 24 s’étendant dans la direction longitudinale avant-arrière X et au moins une traverse avant 26 s’étendant entre les deux longerons avant 24 suivant la direction transversale gauche-droite Y. Des pièces d’interface assurent la jonction entre les longerons avant 24 et les éléments d’angle avant 180. The front part 14 comprises a pair of front spars 24 extending in the front-rear longitudinal direction The interface ensures the junction between the front side members 24 and the front corner elements 180.
La partie arrière 16 comporte une paire de longerons arrière 25 s’étendant dans la direction longitudinale avant-arrière X et au moins une traverse arrière 27 s’étendant entre les deux longerons arrière 25 suivant la direction transversale gauche-droite Y. Des pièces d’interface assurent la jonction entre les longerons arrière 25 et les éléments d’angle arrière 182. The rear part 16 comprises a pair of rear spars 25 extending in the front-rear longitudinal direction The interface ensures the junction between the rear longitudinal members 25 and the rear corner elements 182.
Les longueurs des longerons avant et arrière 24, 25 et des traverses avant et arrière 26, 27 sont variables d’un type de véhicule à l’autre, au sein d’une même gamme de véhicules, suivant la direction des flèches FXAV et FYAV pour la partie avant 14 et suivant la direction des flèches FXAR et FYAR pour la partie arrière 16.The lengths of the front and rear longitudinal members 24, 25 and the front and rear crossmembers 26, 27 vary from one type of vehicle to another, within the same range of vehicles, following the direction of the arrows FXAV and FYAV for the front part 14 and following the direction of the arrows FXAR and FYAR for the rear part 16.
Le plancher central 12 est délimité, à l’avant, par un tablier 28 disposé entre les éléments d’angle avant 180. La partie inférieure du tablier 28 est constituée par le profilé transversal 22 avant. Le tablier 28 forme une cloison séparant le compartiment passager du compartiment avant du véhicule. The central floor 12 is delimited, at the front, by an apron 28 placed between the front corner elements 180. The lower part of the apron 28 is constituted by the front transverse profile 22. The apron 28 forms a partition separating the passenger compartment from the front compartment of the vehicle.
Par ailleurs, le plancher central 12 comporte un tunnel central longitudinal TC qui s’étend suivant la direction longitudinale avant-arrière X sur toute la longueur du plancher central 12. Des traverses sous sièges TS s’étendent suivant la direction
transversale gauche-droite Y et relient le tunnel central TC sur chacun de ses côtés aux profilés longitudinaux ou longerons latéraux ou bavolets 20. Furthermore, the central floor 12 comprises a central longitudinal tunnel TC which extends in the front-rear longitudinal direction left-right transversal Y and connect the central tunnel TC on each of its sides to the longitudinal profiles or side rails or sills 20.
Les pièces d’interface permettant de fixer les longerons avant 24 aux éléments d’angle avant 180 et les pièces d’interface permettant de fixer les longerons arrière 25 aux éléments d’angle arrière 182 sont décrits ci-après en lien avec les figures 5 et 6, dans des modes particuliers de réalisation. The interface parts making it possible to fix the front spars 24 to the front corner elements 180 and the interface parts making it possible to fix the rear spars 25 to the rear corner elements 182 are described below in connection with Figures 5 and 6, in particular embodiments.
La figure 5 montre la fixation entre un longeron avant 24 et un élément d’angle avant 180, dans un mode particulier de réalisation. A titre d’exemple, la figure 5 représente le longeron avant 24 gauche et l’élément d’angle avant 180 gauche. La fixation entre le longeron avant 24 droit et l’élément d’angle avant 180 droit est similaire, étant donné que les éléments d’angle avant 180 gauche et droit et les longerons avant 24 gauche et droit sont symétriques par rapport à la direction longitudinale avant-arrière X. Figure 5 shows the attachment between a front spar 24 and a front corner element 180, in a particular embodiment. As an example, Figure 5 represents the left front spar 24 and the left front corner element 180. The attachment between the right front spar 24 and the right front corner element 180 is similar, given that the left and right front corner elements 180 and the left and right front spars 24 are symmetrical with respect to the longitudinal direction front-back
Comme le montre la figure 5, une pièce d’interface avant 50 présente une première surface 51 fixée au longeron avant 24, par exemple par un ou plusieurs rivets 510 et une seconde surface 52 fixée à l’élément d’interface avant 180 par une ou plusieurs vis 520. As shown in Figure 5, a front interface part 50 has a first surface 51 fixed to the front spar 24, for example by one or more rivets 510 and a second surface 52 fixed to the front interface element 180 by a or several 520 screws.
La figure 6 montre la fixation entre la partie arrière 16 et le plancher central 12 et plus particulièrement la fixation entre un longeron arrière 25 et un élément d’angle arrière 182, dans un mode particulier de réalisation. A titre d’exemple, la figure 6 représente le longeron arrière 25 gauche et l’élément d’angle arrière 182 gauche. La fixation entre le longeron arrière 25 droit et l’élément d’angle arrière 182 droit est similaire, étant donné que les éléments d’angle arrière 182 gauche et droit et les longerons arrière 25 gauche et droit sont symétriques par rapport à la direction longitudinale avant-arrière X. Figure 6 shows the attachment between the rear part 16 and the central floor 12 and more particularly the attachment between a rear spar 25 and a rear corner element 182, in a particular embodiment. As an example, Figure 6 represents the left rear spar 25 and the left rear corner element 182. The attachment between the right rear spar 25 and the right rear corner element 182 is similar, since the left and right rear corner elements 182 and the left and right rear spars 25 are symmetrical with respect to the longitudinal direction front-back
Comme le montre la figure 6, une première pièce d’interface arrière 60 relie, par l’intermédiaire d’un ou plusieurs rivets 600, le profilé longitudinal 20, le profilé transversal 22 arrière et l’élément d’angle arrière 182. Par ailleurs, une seconde pièce d’interface arrière 62 relie, par l’intermédiaire d’une ou plusieurs vis 620, le longeron arrière 25, le profilé transversal 22 arrière et l’élément d’angle arrière 182.
Comme le montre la vue en coupe de la figure 3, de façon optionnelle, l’intérieur de chaque profilé longitudinal ou longeron latéral ou bavolet 20, appelé aussi âme du bavolet, peut être pourvu d’un réseau de nervures 30. Les nervures 30 internes contribuent au renforcement des bavolets 20. As shown in Figure 6, a first rear interface part 60 connects, via one or more rivets 600, the longitudinal profile 20, the rear transverse profile 22 and the rear corner element 182. By elsewhere, a second rear interface part 62 connects, via one or more screws 620, the rear spar 25, the rear transverse profile 22 and the rear corner element 182. As shown in the sectional view in Figure 3, optionally, the interior of each longitudinal profile or lateral spar or sill 20, also called the core of the sill, can be provided with a network of ribs 30. The ribs 30 internal contribute to the reinforcement of the flaps 20.
On peut également doter l’âme des profilés transversaux 22 avant et arrière et/ou des longerons avant et arrière 24, 25 et/ou des traverses avant et arrière 26, 27 d’un réseau de nervures de renforcement. It is also possible to provide the core of the front and rear transverse profiles 22 and/or the front and rear longitudinal members 24, 25 and/or the front and rear crosspieces 26, 27 with a network of reinforcing ribs.
Dans un mode particulier de réalisation, les bavolets 20 de la paire de bavolets sont emmanchés à chacune de leurs extrémités dans des cavités prévues sur les quatre éléments d’angle 18. La paire de bavolets 20 peut en outre être fixée aux éléments d’angle 18 par de la colle et par un ou plusieurs rivets. In a particular embodiment, the flaps 20 of the pair of flaps are fitted at each of their ends into cavities provided on the four corner elements 18. The pair of flaps 20 can also be fixed to the corner elements 18 by glue and by one or more rivets.
Les figures 4A et 4B montrent à titre d’exemple la fixation entre un bavolet 20 et un élément d’angle arrière 182. Le mode de fixation entre un bavolet 20 et un élément d’angle avant 180 est similaire. Ainsi, comme le montrent la vue en coupe de la figure 4A et la vue en perspective de la figure 4B, dans un mode particulier de réalisation, l’extrémité arrière de chaque bavolet de la paire de bavolets 20 est emmanchée dans une cavité prévue dans l’élément d’angle arrière 182 qui reçoit cette extrémité. La forme des parois de la cavité et la forme de la section transversale du bavolet 20 qui y est emmanché sont complémentaires. Figures 4A and 4B show by way of example the attachment between a flap 20 and a rear corner element 182. The method of attachment between a flap 20 and a front corner element 180 is similar. Thus, as shown in the sectional view of Figure 4A and the perspective view of Figure 4B, in a particular embodiment, the rear end of each flap of the pair of flaps 20 is fitted into a cavity provided in the rear corner element 182 which receives this end. The shape of the walls of the cavity and the shape of the cross section of the flap 20 which is fitted there are complementary.
Dans le mode particulier de réalisation des figures 4A et 4B, l’extrémité arrière de chaque bavolet de la paire de bavolets 20 est en outre fixée à l’élément d’angle arrière 182 qui reçoit cette extrémité arrière par de la colle (les parties collées sont indiquées sur la figure 4A par la référence C) et par au moins un rivet 40.In the particular embodiment of Figures 4A and 4B, the rear end of each flap of the pair of flaps 20 is also fixed to the rear corner element 182 which receives this rear end by glue (the parts glued are indicated in Figure 4A by the reference C) and by at least one rivet 40.
Grâce au caractère ajustable des dimensions des bavolets 20, des profilés transversaux 22 avant et arrière, des longerons avant et arrière 24, 25 et des traverses avant et arrière 26, 27, différents types de véhicules, ayant différentes motorisations, différentes liaisons au sol et différentes esthétiques, peuvent être réalisés à partir du châssis 10 conforme à l’invention, sans modifier les éléments d’angle 18, le châssis 10 étant en outre allégé grâce aux éléments d’angle 18 et aux profilés longitudinaux et transversaux 20, 22 tous réalisés en aluminium.
Ainsi, l’invention propose une gamme d’au moins deux types de véhicules automobiles conforme à l’invention comportant chacun un châssis 10 tel que décrit ci-dessus et dans cette gamme, les éléments d’angle avant 180 et les éléments d’angle arrière 182 sont invariants entre les divers types de véhicules, tandis qu’au moins une paire de profilés choisis parmi, soit les profilés longitudinaux 20, soit les profilés transversaux 22 avant et arrière, a une longueur différente pour chacun des divers types de véhicules.
Thanks to the adjustable nature of the dimensions of the flaps 20, the front and rear transverse profiles 22, the front and rear longitudinal members 24, 25 and the front and rear crosspieces 26, 27, different types of vehicles, having different engines, different connections to the ground and different aesthetics, can be produced from the frame 10 according to the invention, without modifying the corner elements 18, the frame 10 being further lightened thanks to the corner elements 18 and the longitudinal and transverse profiles 20, 22 all made of aluminum. Thus, the invention proposes a range of at least two types of motor vehicles conforming to the invention each comprising a chassis 10 as described above and in this range, the front corner elements 180 and the elements of rear angle 182 are invariant between the various types of vehicles, while at least one pair of profiles chosen from either the longitudinal profiles 20 or the transverse profiles 22 front and rear, has a different length for each of the various types of vehicles .
