SYSTEME ΑΝΤΙ-DEVERS A RAIDEUR VARIABLE COMPORTANT DES SERIES DE BARRES QUI S’ECARTENT ENTRE ELLESVERSATILE STIFFNESS ΑΝΤΙ-TILT SYSTEM COMPRISING SERIES OF BARS THAT SPREAD BETWEEN THEM
La présente invention concerne un système anti-dévers pour un train roulant d’un véhicule automobile, ainsi qu’un véhicule automobile équipé d’un tel système.The present invention relates to an anti-tilt system for a running gear of a motor vehicle, as well as a motor vehicle equipped with such a system.
Les véhicules automobiles comportent généralement sur chaque train roulant avant et arrière, une barre anti-dévers comprenant une partie centrale transversale formant une barre de torsion dont les extrémités sont maintenues par deux paliers fixés à la caisse du véhicule, qui se prolonge de chaque côté par une partie latérale coudée dont l’extrémité est reliée à un élément de la suspension.Motor vehicles generally have on each front and rear undercarriage, an anti-roll bar comprising a transverse central part forming a torsion bar, the ends of which are held by two bearings fixed to the body of the vehicle, which is extended on each side by a bent side part, the end of which is connected to an element of the suspension.
Quand le débattement de la suspension entre les deux côtés du train roulant est différent, la barre anti-dévers est soumise à une déformation élastique générant un couple de torsion qui tend à rappeler ces deux côtés dans une position similaire.When the suspension travel between the two sides of the undercarriage is different, the anti-roll bar is subjected to an elastic deformation generating a torque which tends to bring these two sides into a similar position.
On réalise ainsi une fonction anti-dévers limitant les inclinaisons de la caisse du véhicule, notamment dans les virages. Pour assurer le confort et la tenue de route, il faut réaliser un compromis entre la flexibilité et l’amortissement de la suspension, et la flexibilité de la fonction anti-dévers.This provides an anti-roll function limiting the tilting of the vehicle body, especially when cornering. To ensure comfort and handling, a compromise must be made between the flexibility and damping of the suspension, and the flexibility of the anti-roll function.
Un type de système anti-dévers connu comprenant une barre antidévers à flexibilité variable, présenté notamment par le document US-A12006273539, comporte un dispositif variable placé sur la partie centrale de la barre, équipé de trois barres parallèles disposées en triangle dans un plan transversal. Le couple de la barre anti-dévers passe par le dispositif variable qui travaille en torsion.One type of known anti-roll system comprising a variable flexibility anti-roll bar, presented in particular by document US-A12006273539, comprises a variable device placed on the central part of the bar, equipped with three parallel bars arranged in a triangle in a transverse plane. . The torque of the anti-roll bar goes through the variable device which works in torsion.
Un actionneur comportant un moteur et des engrenages fait pivoter ensemble suivant leur axe les barres présentant une section plate, afin de tourner progressivement chaque section plate pour l’amener d’une direction radiale à une direction tangentielle.An actuator comprising a motor and gears rotates together along their axis the bars having a flat section, in order to gradually rotate each flat section to bring it from a radial direction to a tangential direction.
On obtient de cette manière une forte raideur en torsion du dispositif complet quand la section plate des barres est disposée tangentiellement, et une faible raideur quand elle est disposée radialement, qui permet de régler de manière progressive la raideur globale du système anti-dévers.In this way, a high torsional stiffness of the complete device is obtained when the flat section of the bars is arranged tangentially, and a low stiffness when it is arranged radially, which makes it possible to gradually adjust the overall stiffness of the anti-roll system.
Toutefois le dispositif variable comportant les barres pivotantes, soumise aux couples élevés appliqués sur la barre anti-dévers, et subissant des contraintes mécaniques importantes, est complexe à réaliser et entraîne des coûts élevés.However, the variable device comprising the pivoting bars, subjected to the high torques applied to the anti-roll bar, and undergoing significant mechanical stresses, is complex to produce and entails high costs.
La présente invention a notamment pour but d’éviter ces inconvénients de la technique antérieure.The object of the present invention is in particular to avoid these drawbacks of the prior art.
Elle propose à cet effet un système anti-dévers pour train roulant de véhicule automobile, comportant une partie centrale de torsion présentant une direction longitudinale, ce système étant remarquable en ce que la partie centrale de torsion comporte deux séries de barres présentant des extrémités reliées entre elles, chaque série comprenant au moins une barre, et comporte entre ces extrémités un dispositif d’écartement transversal qui écarte les séries de barres l’une de l’autre.To this end, it offers an anti-roll system for the undercarriage of a motor vehicle, comprising a central torsion part having a longitudinal direction, this system being remarkable in that the central torsion part comprises two series of bars having ends connected between them, each series comprising at least one bar, and comprises between these ends a transverse spacing device which separates the series of bars from one another.
Un avantage de ce système anti-dévers est que de manière simple, avec le dispositif d’écartement transversal, en rapprochant les séries de barres entre elles au plus près on obtient une partie centrale présentant un faible moment d’inertie en torsion autour de l’axe, et donc une raideur en torsion réduite, et en écartant progressivement les séries on obtient un moment d’inertie en torsion de plus en plus important qui augmente la raideur en torsion.An advantage of this anti-tilt system is that in a simple way, with the transverse spacing device, by bringing the series of bars together as closely as possible, a central part is obtained having a low moment of inertia in torsion around the axis, and therefore a reduced torsional stiffness, and by progressively discarding the series one obtains a moment of inertia in torsion more and more important which increases the stiffness in torsion.
On notera que les barres subissant des contraintes de torsion élevées sont des éléments simples à fabriquer, effectuant seulement une légère flexion pour écarter radialement leurs parties centrales. On peut réaliser la partie centrale de torsion de manière relativement simple, ce qui entraîne des coûts modérés.It will be noted that the bars undergoing high torsional stresses are elements that are simple to manufacture, performing only a slight bending in order to spread their central parts radially. The central torsion part can be produced relatively simply, which leads to moderate costs.
Le système anti-dévers selon l’invention peut comporter de plus une ou plusieurs des caractéristiques suivantes, qui peuvent être combinées entre elles.The anti-tilt system according to the invention may further include one or more of the following characteristics, which can be combined with one another.
Avantageusement, chaque barre présente une largeur au moins trois fois supérieure à son épaisseur.Advantageously, each bar has a width at least three times greater than its thickness.
Dans ce cas, chaque série de barres peut comporter plusieurs barres superposées à plat.In this case, each series of bars can have several bars superimposed flat.
Avantageusement, les extrémités des séries de barres sont reliées entre elles par un manchon de liaison recevant à l’intérieur ces extrémités.Advantageously, the ends of the series of bars are connected together by a connecting sleeve receiving these ends inside.
Avantageusement, le dispositif d’écartement transversal comporte deux supports superposés, fixés chacun à une série de barres.Advantageously, the transverse spacing device comprises two superimposed supports, each fixed to a series of bars.
Dans ce cas, les deux supports sont avantageusement reliés entre eux par un moyen d’écartement.In this case, the two supports are advantageously connected together by a spacer.
En particulier, les moyens d’écartement peuvent comporter deux colonnettes parallèles, chacune étant fixée sur un support, et coulissant dans l’autre support.In particular, the spacing means may include two parallel posts, each being fixed on a support, and sliding in the other support.
Avantageusement, le dispositif d'écartement transversal comporte une motorisation réalisant un mouvement d’écartement des deux séries de barres qui n’est pas réversible.Advantageously, the transverse spacing device comprises a motorization performing a spacing movement of the two series of bars which is not reversible.
Dans ce cas, avantageusement la motorisation comporte un réducteur du type roue et vis sans fin.In this case, advantageously the motorization comprises a reduction gear of the wheel and worm type.
L’invention a aussi pour objet un véhicule automobile comprenant un train roulant équipé d'un système anti-dévers présentant l’une quelconque des caractéristiques précédentes.The subject of the invention is also a motor vehicle comprising a running gear equipped with an anti-roll system having any of the preceding characteristics.
L’invention sera mieux comprise et d’autres caractéristiques et avantages apparaîtront plus clairement à la lecture de la description ci-après donnée à titre d’exemple, en référence aux dessins annexés dans lesquels :The invention will be better understood and other characteristics and advantages will appear more clearly on reading the description below given by way of example, with reference to the accompanying drawings in which:
- la figure 1 est une vue schématique d’un train avant de véhicule automobile comportant un système anti-dévers selon l’invention ;- Figure 1 is a schematic view of a front axle of a motor vehicle comprising an anti-roll system according to the invention;
- la figure 2 est une vue détaillée de ce système anti-dévers ; et- Figure 2 is a detailed view of this anti-roll system; and
- la figure 3 est une vue détaillée du dispositif d’écartement transversal des barres de ce système anti-dévers.- Figure 3 is a detailed view of the transverse spacing device for the bars of this anti-tilt system.
Les figures 1 et 2 présentent un train avant de véhicule automobile comportant de chaque côté un triangle inférieur de suspension 2 relié au véhicule du côté intérieur par un pivot 18 disposé dans l’axe de ce véhicule, qui supporte du côté extérieur une roue avant 4.Figures 1 and 2 show a front axle of a motor vehicle comprising on each side a lower suspension triangle 2 connected to the vehicle on the inside by a pivot 18 disposed in the axis of this vehicle, which supports on the outside a front wheel 4 .
Un combiné 6 comportant un ressort et un amortisseur télescopique, est disposé sensiblement verticalement entre le bras de suspension 2 et la caisse du véhicule pour amortir les mouvements de la suspension.A handset 6 comprising a spring and a telescopic damper is disposed substantially vertically between the suspension arm 2 and the body of the vehicle to dampen the movements of the suspension.
Un système anti-dévers reliant les deux bras de suspension 2, comporte une partie centrale 10 allongée dans la direction transversale du véhicule, comprenant deux séries de barres 20 disposées parallèlement, les extrémités de ces barres étant reliées ensemble de chaque côté par un manchon de liaison 12 recevant à l’intérieur ces extrémités, maintenu sur la caisse du véhicule par un palier non représenté.An anti-tilt system connecting the two suspension arms 2, comprises a central part 10 elongated in the transverse direction of the vehicle, comprising two series of bars 20 arranged in parallel, the ends of these bars being connected together on each side by a sleeve of link 12 receiving inside these ends, held on the vehicle body by a bearing not shown.
Chaque manchon de liaison 12 se prolonge vers l’extérieur par une partie extérieure coudée 14, reliée au bras de suspension 2 par une biellette 16 équipée à ses extrémités de rotules.Each connecting sleeve 12 is extended towards the outside by an angled external part 14, connected to the suspension arm 2 by a link 16 fitted at its ends with ball joints.
Chaque série de barres parallèles comporte deux barres 20 présentant une section transversale plate sensiblement rectangulaire, comprenant une largeur au moins trois fois supérieure à son épaisseur, qui sont posées à plat l’un sur l’autre en se déformant ensemble. Dans cet exemple les deux séries de barres 20 sont superposées verticalement, pour former une série supérieure et une série inférieure disposées symétriquement par rapport à un plan médian.Each series of parallel bars comprises two bars 20 having a substantially rectangular flat cross section, comprising a width at least three times greater than its thickness, which are laid flat one on the other while being deformed together. In this example, the two series of bars 20 are superimposed vertically, to form an upper series and a lower series arranged symmetrically with respect to a median plane.
Un dispositif d’écartement transversal 22 disposé au milieu de la partie centrale 10 de la barre anti-dévers, comporte un support supérieur 34 fixé à plat sur la série supérieure de barres 20, et un support inférieur 36 superposé en dessous de ce support supérieur, qui est fixé à plat sur la série inférieure de barres.A transverse spacing device 22 disposed in the middle of the central part 10 of the anti-roll bar, comprises an upper support 34 fixed flat on the upper series of bars 20, and a lower support 36 superimposed below this upper support , which is fixed flat on the lower series of bars.
Deux colonnettes parallèles 38 disposées de chaque côté des barres 20, perpendiculairement à la forme plate de ces barres, coulissent au travers du support supérieur 34, leurs extrémités inférieures étant fixées au support inférieur 36.Two parallel columns 38 placed on each side of the bars 20, perpendicular to the flat shape of these bars, slide through the upper support 34, their lower ends being fixed to the lower support 36.
Un moteur électrique 30 fixé sur un carter 32 lié au support supérieur 34, transmet par un réducteur un mouvement qui repousse vers le bas les extrémités supérieures des colonnettes 38, ce qui déplace vers le bas le support inférieur 36 par rapport à ce support supérieur.An electric motor 30 fixed on a casing 32 linked to the upper support 34, transmits by a reduction gear a movement which pushes down the upper ends of the balusters 38, which moves the lower support 36 downwards relative to this upper support.
On obtient une flexion opposée des deux séries de barres 20 qui écarte ces séries l’une de l’autre, leurs extrémités restant liées entre elles par les manchons de liaison 12. La partie centrale 10 de la barre anti-dévers présente alors un moment d’inertie en torsion qui augmente. La raideur de la barre anti-dévers est réglable de cette manière.An opposite bending of the two series of bars 20 is obtained which separates these series from one another, their ends remaining linked together by the connecting sleeves 12. The central part 10 of the anti-roll bar then has a moment increasing torsional inertia. The stiffness of the anti-roll bar is adjustable in this way.
La section plate des barres 20 permet de leur donner une faible raideur en flexion suivant l’épaisseur, qui facilite le travail du dispositif d’écartement. On superpose alors plusieurs barres 20 dans une même série pour obtenir la raideur en torsion recherchée pour chaque série.The flat section of the bars 20 makes it possible to give them a low bending stiffness along the thickness, which facilitates the work of the spacer device. Several bars 20 are then superimposed in the same series to obtain the desired torsional stiffness for each series.
On peut en variante utiliser une autre section, ou disposer par série une seule barre 20 ou plus de deux.One can alternatively use another section, or arrange in series a single bar 20 or more than two.
La figure 3 présente le moteur électrique 30 comportant sur son arbre de sortie une vis sans fin 40, qui entraîne une roue 42 portée par un axe 44 maintenu par deux paliers fixés sur le support supérieur 34.FIG. 3 shows the electric motor 30 comprising on its output shaft an endless screw 40, which drives a wheel 42 carried by an axle 44 held by two bearings fixed on the upper support 34.
Le réducteur à roue 42 et vis sans fin 40 a pour avantage de présenter un mouvement qui n’est pas réversible, le couple appliqué sur cette roue par les séries de barres 20 déformées élastiquement ne peuvent pas entraîner une rotation du moteur électrique 30 ce qui permet d’arrêter la commande de ce moteur pour maintenir une position.The reduction gear with wheel 42 and worm 40 has the advantage of having a movement which is not reversible, the torque applied to this wheel by the series of bars 20 elastically deformed cannot cause rotation of the electric motor 30 which stops the control of this motor to maintain a position.
Un basculeur 46 fixé sur l’axe 44 entre les deux paliers supportant cet axe, comporte au bout de son bras de levier un arbre 48 parallèles à l’axe, dont chaque côté presse sur une extrémité d’une colonnette 38.A rocker 46 fixed on the axis 44 between the two bearings supporting this axis, comprises at the end of its lever arm a shaft 48 parallel to the axis, each side of which presses on one end of a baluster 38.
Une rotation du moteur électrique 30 entraîne avec une forte réduction de vitesse et donc un couple élevé, une rotation de l’axe 44 qui fait pivoter le basculeur 46. L’arbre 48 du basculeur 46 presse sur les extrémités des colonnettes 38 qui descendent, en entraînant le support inférieur 36 ce qui écarte les deux séries de barres 20.A rotation of the electric motor 30 causes, with a strong reduction in speed and therefore a high torque, a rotation of the axis 44 which makes the rocker 46 pivot. The shaft 48 of the rocker 46 presses on the ends of the balusters 38 which descend, by driving the lower support 36 which separates the two series of bars 20.
Le moteur électrique 30 est commandé par une unité de contrôle électronique, recevant différentes informations sur le fonctionnement du véhicule, notamment la vitesse du véhicule, la demande du conducteur pour un mode plus sportif ou plus confortable, et les accélérations de ce véhicule dans différentes directions, pour calculer la raideur optimale de la barre antidévers permettant de répondre aux exigences de confort et de sécurité.The electric motor 30 is controlled by an electronic control unit, receiving various information on the operation of the vehicle, in particular the speed of the vehicle, the driver's request for a more sporty or more comfortable mode, and the accelerations of this vehicle in different directions. , to calculate the optimal stiffness of the anti-roll bar to meet comfort and safety requirements.
On peut en particulier obtenir une variation de raideur très progressive et rapide, qui permet de donner une réponse adaptée dans des circonstances délicates. En particulier on peut contrôler efficacement le roulis du véhicule dans une succession de virages inverses pris rapidement, entraînant un roulis dans un sens puis dans l’autre qui pourrait être dangereux pour la stabilité de ce véhicule.One can in particular obtain a very gradual and rapid variation in stiffness, which makes it possible to give an adapted response in delicate circumstances. In particular, it is possible to effectively control the roll of the vehicle in a succession of reverse turns taken quickly, causing roll in one direction then in the other which could be dangerous for the stability of this vehicle.
En variante le dispositif d’écartement peut comporter tout autre type de motorisation, comme une motorisation hydraulique, électrohydraulique ou pneumatique. Le réducteur de vitesse peut aussi être formé de différentes manières.As a variant, the spacing device may include any other type of motorization, such as a hydraulic, electrohydraulic or pneumatic motorization. The speed reducer can also be formed in different ways.
