Description

CHASSIS DE VEHICULE AVEC LOGEMENT DE DISPOSITIF DE STOCKAGE VEHICLE CHASSIS WITH STORAGE DEVICE HOUSING
D'ENERGIEENERGY
La présente invention vise un châssis pour un véhicule, en particulier un véhicule de petite dimension.The present invention is directed to a chassis for a vehicle, in particular a small vehicle.
Le but de l'invention est de proposer un châssis offrant une bonne résistance mécanique et un bon comportement en cas de choc, notamment frontal.The object of the invention is to provide a frame with good mechanical strength and good behavior in case of impact, including frontal.
Selon un premier aspect, l'invention concerne un châssis comportant deux longerons intérieurs qui s'étendent selon la direction longitudinale du véhicule, un premier dispositif de stockage d'énergie qui est adapté à alimenter un moteur et qui est disposé dans un premier logement délimité latéralement par les longerons intérieurs, deux longerons extérieurs qui s'étendent selon la direction longitudinale du véhicule et qui sont disposés de part et d'autre des longerons intérieurs, et, dans un second logement délimité par les longerons extérieurs, à l'arrière du premier logement, un second dispositif de stockage d'énergie qui est adapté à alimenter le moteur et/ou le moteur lui-même.According to a first aspect, the invention relates to a chassis comprising two inner longitudinal members which extend in the longitudinal direction of the vehicle, a first energy storage device which is adapted to power a motor and which is arranged in a first delimited housing laterally by the inner spars, two outer spars which extend in the longitudinal direction of the vehicle and which are arranged on either side of the inner spars, and, in a second housing delimited by the outer spars, to the rear of the first housing, a second energy storage device which is adapted to supply the motor and / or the motor itself.
Ainsi, en cas de choc, les éléments lourds qui sont disposés dans les logements sont entourés par les longerons, ce qui permet de les maintenir dans le châssis, et d'absorber la poussée que ces éléments génèrent alors. Selon un deuxième aspect, l'invention concerne un véhicule automobile comprenant des roues avant et arrière et un châssis s' étendant à la hauteur des roues avant et arrière, ledit châssis comportant deux longerons intérieurs qui s'étendent selon la direction longitudinale du véhicule, un bouclier avant qui s'étend selon la direction transversale du véhicule et qui forme l'extrémité avant du châssis , et des éléments absorbeur de choc , le châssis comprend deux longerons extérieurs qui s'étendent selon la direction longitudinale du véhicule qui sont disposés de part et d' autre des longerons intérieurs et qui chacun supportent une roue avant et une roue arrière, les éléments absorbeurs de choc étant disposés longitudinalement entre, d'une part, l'extrémité avant des longerons intérieurs et extérieurs, et, d'autre part, le bouclier avant.Thus, in case of shock, the heavy elements that are arranged in the housing are surrounded by the side members, which allows to keep them in the frame, and absorb the thrust that these elements generate then. According to a second aspect, the invention relates to a motor vehicle comprising front and rear wheels and a chassis extending at the height of the front and rear wheels, said chassis comprising two inner longitudinal members which extend in the longitudinal direction of the vehicle, a front shield which extends in the transverse direction of the vehicle and which forms the front end of the chassis, and shock absorber elements, the chassis comprises two outer longitudinal members which extend in the longitudinal direction of the vehicle which are disposed of on both sides and each supporting a front wheel and a rear wheel, the shock absorbing elements being arranged longitudinally between, on the one hand, the front end of the inner and outer side members, and, on the other hand, the front bumper.
Ainsi, la multiplicité des longerons permet, en cas de choc, d'assurer une bonne rigidité du châssis tout en employant des éléments absorbeur de choc occupant un volume peu important. Selon un troisième aspect, l'invention concerne un châssis de véhicule, comportant deux longerons extérieurs qui s'étendent selon la direction longitudinale du véhicule, deux longerons intérieurs s' étendant selon la direction longitudinale du véhicule et disposés entre les deux longerons extérieurs, un bouclier avant qui s'étend selon la direction transversale du véhicule et qui forme l'extrémité avant du châssis, des éléments absorbeur de choc disposés longitudinalement entre l'extrémité avant des longerons et le bouclier avant. Chaque longeron extérieur porte une patte transversale qui fait face à une patte complémentaire transversale correspondante portée par le bouclier , et qui est adaptée, avec cette patte complémentaire transversale correspondante, à comprimer une roue avant de véhicule quand l'élément absorbeur de choc est déformé. Ainsi, les roues avant participent à l'absorption de l'énergie lors d'un choc frontal, ce qui permet d'augmenter la sécurité du véhicule.Thus, the multiplicity of longitudinal members allows, in case of impact, to ensure good rigidity of the chassis while employing shock absorber elements occupying a small volume. According to a third aspect, the invention relates to a vehicle chassis, comprising two outer longitudinal members which extend in the longitudinal direction of the vehicle, two inner longitudinal members extending in the longitudinal direction of the vehicle and arranged between the two outer longitudinal members, a front shield which extends in the transverse direction of the vehicle and which forms the front end of the frame, shock absorber elements disposed longitudinally between the front end of the longitudinal members and the front bumper. Each outer beam carries a transverse tab which faces a corresponding transverse complementary tab carried by the shield, and which is adapted, with this corresponding transverse complementary tab, to compress a vehicle front wheel when the shock absorber element is deformed. Thus, the front wheels participate in the absorption of energy during a frontal impact, which increases the safety of the vehicle.

Un véhicule conforme à la présente invention comporte à la hauteur de ses roues avant 1 et arrière 2, un châssis 3 qui comprend deux longerons 4, 5, dits extérieurs, qui s'étendent selon la direction longitudinale du véhicule. Les longerons extérieurs 4, 5 sont formés d'un seul tenant. En outre, ces longerons 4, 5 sont, vue de dessus, sensiblement rectilignes et s'étendent ainsi dans des plans verticaux parallèles. Ces longerons sont d'un seul tenant et s'étendent donc de manière continue. La continuité des longerons extérieurs 4, 5 permet de réaliser un châssis simple présentant une rigidité importante aux chocs longitudinaux tout en préservant la flexibilité de la structure. Dans le mode de réalisation représenté, les longerons extérieurs 4, 5 s'étendent sensiblement d'un bout à l'autre du châssis. Chaque longeron extérieur 4, 5 supporte une roue avant 1 et une roue arrière 2.A vehicle according to the present invention comprises at the height of its front wheels 1 and rear 2, a frame 3 which comprises two longitudinal members 4, 5, said outer, which extend in the longitudinal direction of the vehicle. The outer beams 4, 5 are formed in one piece. In addition, these longitudinal members 4, 5 are, seen from above, substantially rectilinear and thus extend in parallel vertical planes. These spars are in one piece and therefore extend continuously. The continuity of the outer beams 4, 5 allows for a simple frame having a high rigidity longitudinal shocks while preserving the flexibility of the structure. In the embodiment shown, the outer beams 4, 5 extend substantially from one end to the other of the frame. Each outer spar 4, 5 supports a front wheel 1 and a rear wheel 2.
Outre ces deux longerons 4, 5 , le châssis 3 comprend également deux longerons intérieurs 6, 7 qui s'étendent également selon la direction longitudinale du véhicule, les deux longerons intérieurs 6, 7 étant disposés entre les deux longerons extérieurs 4, 5. Les longerons intérieurs 6, 7 sont sensiblement rectilignes.In addition to these two side members 4, 5, the chassis 3 also comprises two inner longitudinal members 6, 7 which also extend in the longitudinal direction of the vehicle, the two inner longitudinal members 6, 7 being arranged between the two outer longitudinal members 4, 5. The inner longitudinal members 6, 7 are substantially rectilinear.
Dans le présent exemple, les longerons extérieurs 4, 5 et intérieurs 6, 7 sont réalisés sous forme de profilés tubulaires. Les longerons intérieurs 6, 7 et extérieurs 4, 5 présentent donc une section sensiblement constante sur toute leur longueur. Par ailleurs, dans le présent exemple dans lequel le véhicule ne comprend, en première ligne, qu'un siège avant qui est disposé selon l'axe médian du véhicule, ce siège est fixé directement ou indirectement sur les longerons intérieurs 6, 7.In the present example, the outer longitudinal members 4, 5 and inner 6, 7 are made in the form of tubular sections. The inner longitudinal members 6, 7 and 4, 5 thus have a substantially constant section over their entire length. Furthermore, in the present example in which the vehicle comprises, in the first line, only a front seat which is arranged along the median axis of the vehicle, this seat is fixed directly or indirectly to the inner longitudinal members 6, 7.
Le véhicule comporte également un groupe moteur constitué d'un moteur électrique accompagné éventuellement d'un réducteur et d'un variateur de vitesse ainsi que de dispositifs de stockage d'énergie destinés à la propulsion du véhicule et adaptés à alimenter le moteur. Les dispositifs de stockage d'énergie sont ici des batteries, mais pourraient être des réservoirs de stockage de gaz (hydrogène, air comprimé etc.) ou des combinaisons batteries-réservoirs. Afin de permettre le rangement de ces éléments, le châssis 3 comporte deux logements 8, 9. Un premier logement 8 (ici, adapté à recevoir un dispositif de stockage d'énergie) est délimité latéralement par les longerons intérieurs 6, 7. Le second logement 9 (ici, adapté à recevoir soit un autre dispositif de stockage d'énergie, soit au moins une partie du groupe moteur) est délimité par les longerons extérieurs 4, 5 et est situé à l'arrière du premier logement 8.The vehicle also comprises a power unit consisting of an electric motor optionally accompanied by a gearbox and a variable speed drive as well as energy storage devices for the propulsion of the vehicle and adapted to power the engine. The energy storage devices here are batteries, but could be storage tanks for gas (hydrogen, compressed air, etc.) or battery-tank combinations. To allow the storage of these elements, the frame 3 comprises two housings 8, 9. A first housing 8 (here, adapted to receive an energy storage device) is delimited laterally by the inner longitudinal members 6, 7. The second housing 9 (here, adapted to receive either another energy storage device or at least a portion of the power unit) is delimited by the outer beams 4, 5 and is located behind the first housing 8.
Le châssis 3 comporte également une traverse principale 10 qui s'étend selon la direction transversale du véhicule. La traverse principale est située entre le premier 8 et le second logement 9. Dans le présent exemple, la traverse principale 10 forme la limite avant du second logement 9, et la limite arrière du premier logement 8. La traverse principale 10 est fixée aux longerons extérieurs 4, 5 et aux extrémités arrière des longerons intérieurs 6, 7. Lors d'un choc frontal, la traverse principale 10 sert d'arrêt aux éléments contenus dans le second logement 9, et l'énergie mécanique provenant de la poussée réalisée par ces éléments est transmise aux longerons intérieurs 6, 7 et extérieurs 4, 5.The chassis 3 also comprises a main cross member 10 which extends in the transverse direction of the vehicle. The main transom is located between the first 8 and the second housing 9. In the present example, the main transom 10 forms the front limit of the second housing 9, and the rear limit of the first housing 8. The main cross member 10 is fixed to the outer longitudinal members 4, 5 and the rear ends of the inner longitudinal members 6, 7. In a frontal impact, the main cross member 10 serves as a stop for the elements contained in the second housing 9, and the mechanical energy from the thrust produced by these elements is transmitted to the inner longitudinal members 6, 7 and 4, 5.
De façon plus précise, les longerons extérieurs 4, 5 comprennent une plaque latérale 21 à leur partie arrière, cette plaque latérale 21 formant un coté latéral du second logement 9. La traverse principale 10 est fixée aux extrémités avant de ces plaques latérales 21 et sur la partie avant de ces mêmes longerons 4, 5 (cf. figures 1 et 2) .More specifically, the outer beams 4, 5 comprise a side plate 21 at their rear part, this side plate 21 forming a lateral side of the second housing 9. The main cross member 10 is fixed to the front ends of these side plates 21 and on the front part of these same longitudinal members 4, 5 (see Figures 1 and 2).
Le châssis 3 comporte également une traverse avant 11 qui s'étend selon la direction transversale du véhicule. Cette traverse avant 11 qui forme la limite avant du premier logement 8. Cette traverse avant 11 est fixée aux longerons intérieurs 6, 7 et elle ne s'étend qu'entre ces derniers. Lors d'un choc frontal, la traverse avant 11 sert d'arrêt aux éléments contenus dans le premier logement 8, et l'énergie mécanique provenant de la poussée réalisée par ces éléments est transmise aux longerons intérieurs 6, 7. La traverse avant 11 est disposée horizontalement en vis-à-vis de la traverse principale 10. Le châssis 3 comporte également une traverse arrière 22 qui s'étend selon la direction transversale du véhicule et qui forme la limite arrière du second logement 9. Cette traverse arrière 22 est fixée aux longerons extérieurs 4, 5.The chassis 3 also comprises a front cross member 11 which extends in the transverse direction of the vehicle. This front cross member 11 which forms the front limit of the first housing 8. This front cross member 11 is attached to the inner longitudinal members 6, 7 and extends only between them. In a frontal impact, the front cross member 11 serves to stop the elements contained in the first housing 8, and the mechanical energy from the thrust produced by these elements is transmitted to the inner longitudinal members 6, 7. The front cross member 11 is arranged horizontally opposite the main cross member 10. The frame 3 also comprises a rear cross member 22 which extends in the transverse direction of the vehicle and which forms the rear limit of the second housing 9. This rear cross member 22 is attached to the outer beams 4, 5.
Par ailleurs, le châssis 3 comporte des éléments absorbeur de choc 12, 13 (ici, deux éléments) ainsi qu'un bouclier avant 14 qui s'étend selon la direction transversale et qui forme l'extrémité avant du châssis 3. Ces éléments absorbeurs de choc 12, 13 sont disposés longitudinalement entre, d'une part, l'extrémité avant des longerons intérieurs 6, 7 et extérieurs 4, 5, et, d'autre part, le bouclier avant 14. Ainsi, lors d'un choc frontal, les poussées transmises aux longerons intérieurs 6, 7 et extérieurs 4, 5 par les traverses 10, 11 sont transmises aux éléments absorbeur de choc 12, 13 qui se déforment en conséquence.Furthermore, the chassis 3 comprises shock absorber elements 12, 13 (here, two elements) and a front shield 14 which extends in the transverse direction and which forms the front end of the chassis 3. These absorber elements 12, 13 are arranged longitudinally between, on the one hand, the front end of the inner longitudinal members 6, 7 and 4, 5, and, secondly, the front bumper 14. Thus, during a frontal impact, the thrusts transmitted to the inner longitudinal members 6, 7 and 4, 5 by the cross members 10, 11 are transmitted to the elements shock absorber 12, 13 which deform accordingly.
De façon plus précise, afin d'améliorer la transmission de l'énergie aux éléments absorbeur de choc 12, 13, l'extrémité avant de chaque longeron intérieur 6, 7 est reliée à l'extrémité avant du longeron extérieur 4, 5 adjacent correspondant par une pièce de liaison 15, 16 sur laquelle prend appui l'élément absorbeur de choc 12, 13 correspondant. Cette pièce de liaison 15, 16 s'étend selon la direction transversale du véhicule et, dans le présent mode de réalisation est formée par une plaque qui ne s'étend qu'entre les deux longerons 4, 6 ; 5, 7 qu'elle relie (cf. figure 6) . De même la dimension transversale de chaque élément absorbeur de choc 12, 13 correspond à la somme de celles de la pièce de liaison et des deux longerons correspondants.More specifically, in order to improve the transmission of energy to the shock absorber elements 12, 13, the front end of each inner spar 6, 7 is connected to the front end of the corresponding adjacent outer spar 4, 5 by a connecting piece 15, 16 on which bears the shock absorber element 12, 13 corresponding. This connecting piece 15, 16 extends in the transverse direction of the vehicle and in the present embodiment is formed by a plate which extends between the two longitudinal members 4, 6; 5, 7 which it connects (see Figure 6). Similarly, the transverse dimension of each shock absorber element 12, 13 corresponds to the sum of those of the connecting piece and the two corresponding longitudinal members.
Ainsi, le châssis est formé d'au moins deux cadres assurant la rigidité du véhicule et permettant de transmettre l'énergie cinétique aux éléments absorbeur de choc 12, 13 lors d'un choc frontal notamment. Le premier cadre intérieur est formé de la traverse principale 10, des longerons intérieurs 6, 7, des éléments absorbeur de choc 12, 13 et du bouclier avant 14. Le second cadre est formé de la traverse principale 10, des longerons extérieurs 4, 5, des éléments absorbeur de choc 12, 13 et du bouclier avant 14. En outre, le châssis peut également comporter un troisième cadre formé par une traverse arrière 22, les longerons extérieurs 4, 5 et la traverse principale 10. On notera que l'énergie cinétique est d'autant mieux transmise aux éléments absorbeur de choc 12, 13 que les longerons intérieurs et extérieurs sont sensiblement rectilignes et continues. Enfin, afin de permettre une meilleure absorption d'énergie en cas de choc frontal, dans le présent exemple, chaque longeron extérieur 4, 5 porte une patte transversale 17, 18. La patte transversale 17, 18 fait saillie vers l'extérieur du châssis par rapport aux longerons extérieurs 4, 5 et s'étend transversalement à la direction longitudinale du véhicule. Chaque patte transversale 17, 18 fait face à une patte complémentaire transversale 19, 20 qui est portée par le bouclier avant 14. Chaque roue avant 1 est disposée longitudinalement entre une patte transversale 17, 18 et la patte complémentaire transversale 19, 20 correspondante, et est comprimée par ces dernières quand l'élément absorbeur de choc 12, 13 correspondant est déformé (voir figure 7) . Ainsi, lors d'un choc frontal, des éléments absorbeur de choc 12, 13 se compriment et les roues avant 1, prises en étau, sont également comprimées et participent à l'amortissement du choc. Par ailleurs, des cornières de renfort 23, 24 sont disposées au niveau de l'équerre arrière que forment le longeron extérieur 4, 5 et la patte transversale 17, 18 correspondants. L'extrémité avant de chaque longeron 4, 5 porte des moyens de fixation de la roue avant 1 permettant un déplacement de chaque roue avant 1 sensiblement selon la direction longitudinale lors d'un choc frontal quand les éléments absorbeur de choc sont déformés. Ces moyens de fixation comprennent de préférence un montage par triangle de suspension .Thus, the frame is formed of at least two frames ensuring the rigidity of the vehicle and for transmitting the kinetic energy to the shock absorber elements 12, 13 during a frontal impact in particular. The first inner frame is formed of the main cross member 10, inner longitudinal members 6, 7, shock absorber elements 12, 13 and the front bumper 14. The second frame is formed of the main cross member 10, outer side members 4, 5 , shock absorbing elements 12, 13 and the front bumper 14. In addition, the frame may also include a third frame formed by a rear cross member 22, the outer members 4, 5 and the main cross member 10. It will be noted that the Kinetic energy is all the better transmitted to the shock absorber elements 12, 13 that the inner and outer longitudinal members are substantially rectilinear and continuous. Finally, to allow better energy absorption in the event of a frontal impact, in the present example, each outer spar 4, 5 carries a transverse lug 17, 18. The transverse lug 17, 18 protrudes outwardly from the frame relative to the outer beams 4, 5 and extends transversely to the longitudinal direction of the vehicle. Each transverse lug 17, 18 faces a transverse complementary lug 19, 20 which is carried by the front bumper 14. Each front wheel 1 is disposed longitudinally between a transverse lug 17, 18 and the corresponding transverse lug 19, 20, and is compressed by the latter when the corresponding shock absorber element 12, 13 is deformed (see Figure 7). Thus, during a frontal impact, shock absorber elements 12, 13 are compressed and the front wheels 1, taken in a vice, are also compressed and participate in shock absorption. Furthermore, reinforcement angles 23, 24 are arranged at the rear bracket formed by the outer spar 4, 5 and the corresponding transverse lug 17, 18. The front end of each beam 4, 5 carries means for fixing the front wheel 1 allowing a displacement of each front wheel 1 substantially in the longitudinal direction during a frontal impact when the shock absorber elements are deformed. These fixing means preferably comprise a mounting by suspension triangle.
Le plancher du véhicule représenté sur les figures 8 et 9 est fixé sur les longerons 4, 5, 6, 7 et forme la limite supérieure des deux logements 8, 9, l'accès à ces derniers étant possible grâce à la présence de plaques inférieures amovibles qui forment leur limite inférieure. Le plancher est en fait constitué de plusieurs éléments 25, 26, 27a, 27b, 28. Ces éléments de plancher 25, 26, 27a, 27b, 28 sont réalisés à partir de plaques de tôle formées et fixées aux longerons, de préférence par soudage. Ces éléments de plancher 25, 26, 27a, 27b, 28, 29 sont solidarisés aux longerons extérieurs 4, 5 et aux longerons extérieurs 6, 7, par soudage de préférence. Le plancher comporte notamment un élément central 25 venant recouvrir le premier logement 8 et un élément central 26 venant recouvrir le second logement 9. Ces éléments 25, 26 de plancher permettent de recevoir les moyens de fixation du siège avant et des sièges arrière. Par ailleurs, la plancher comporte des éléments de plancher latéraux 27a, 27b. Ces éléments latéraux 27a, 27b s'étendent de part et d'autre du premier logement 8 et sont fixés sur les longerons extérieurs 4, 5. Les longerons extérieurs 4, 5 présentent un léger décrochement vers le bas au niveau du premier 8 et du second logement. Ainsi, les éléments latéraux 27a, 27b de plancher sont disposés à un niveau inférieur aux éléments centraux 25, 26 de plancher venant recouvrir le premier 8 et le second logement 9 et formant ainsi un niveau inférieur de plancher. Cette disposition permet de faciliter l'accès au véhicule. Dans le mode de réalisation représenté, les éléments latéraux 27a, 27 présentent une échancrure 29 facilitant encore davantage l'accessibilité à l'habitacle du véhicule. Enfin, le plancher comporte également un élément avant 28 pour recevoir les pieds du conducteur.The floor of the vehicle shown in Figures 8 and 9 is fixed on the longitudinal members 4, 5, 6, 7 and forms the upper limit of the two housing 8, 9, access to the latter being possible due to the presence of lower plates which form their lower limit. The floor is in fact made of several elements 25, 26, 27a, 27b, 28. These floor elements 25, 26, 27a, 27b, 28 are made from sheet metal plates formed and fixed to the longitudinal members, preferably by welding. These floor members 25, 26, 27a, 27b, 28, 29 are secured to the outer beams 4, 5 and the outer beams 6, 7, preferably by welding. The floor comprises in particular a central element 25 coming to cover the first housing 8 and a central element 26 coming to cover the second housing 9. These floor elements 25, 26 make it possible to receive the fastening means of the front seat and the rear seats. In addition, the floor has lateral floor elements 27a, 27b. These lateral elements 27a, 27b extend on either side of the first housing 8 and are fixed on the outer longitudinal members 4, 5. The outer longitudinal members 4, 5 have a slight step downward at the first 8 and the second accommodation. Thus, the floor side members 27a, 27b are arranged at a lower level than the central floor elements 25, 26 from covering the first 8 and the second housing 9 and thus forming a lower floor level. This arrangement makes it easier to access the vehicle. In the embodiment shown, the lateral elements 27a, 27 have a notch 29 further facilitating accessibility to the passenger compartment of the vehicle. Finally, the floor also includes a front element 28 for receiving the driver's feet.
On note en outre que les longerons intérieurs 6, 7 et extérieurs 4, 5 sont situés, en hauteur, sensiblement à même niveau, ce niveau correspondant à celui de l'axe des roues. Les logements 8, 9 sont de préférence situés à ce même niveau.It is further noted that the inner longitudinal members 6, 7 and 4, 5 are located, in height, substantially at the same level, this level corresponding to that of the axis of the wheels. The housings 8, 9 are preferably located at this same level.
La présente invention n'est pas limitée au présent mode de réalisation. Elle pourrait également concerner un véhicule à piles à combustible, les logements étant alors destinés à recevoir les réservoirs de carburant et/ou la pile à combustible. Elle pourrait aussi concerner un véhicule à propulsion par gaz (par ex de l'air comprimé), les logements étant alors destinés à recevoir les réservoirs de gaz sous pression et /ou le moteur à gaz.The present invention is not limited to the present embodiment. It could also relate to a fuel cell vehicle, the housing then being intended to receive the fuel tanks and / or the fuel cell. It could also concern a vehicle propelled by gas (eg compressed air), housing then being intended to receive the pressurized gas tanks and / or the gas engine.
Il serait par ailleurs possible que la pièce de liaison s'étend entre les deux longerons en recouvrant leur extrémité (elle est alors fixée sur la tranche du bout des longerons) . It would also be possible for the connecting piece to extend between the two longitudinal members by covering their end (it is then fixed on the edge of the end of the longitudinal members).
