Description
BARRE ANTI-DEVERS FILTRANTE POUR VEHICULE AUTOMOBILE FILTERING ANTI-DEVRY BAR FOR MOTOR VEHICLE
La présente invention concerne une barre anti-devers filtrante pour train roulant de véhicule automobile, ainsi qu'un véhicule équipé d'une telle barre anti-devers. Les véhicules automobiles comportent généralement sur le train avant, et dans certains cas sur le train arrière, une barre anti-dévers. Une barre anti-devers d'un type connu, décrite notamment dans le document EP-B1-0631891, présente une partie centrale transversale dont les extrémités sont maintenues par des paliers liés à la caisse du véhicule, et des parties latérales dépassant vers l'extérieur des paliers. Les parties latérales de la barre anti-dévers comportent un coude pour réaliser un bras de levier, qui se termine par une articulation reliée à une biellette. Cette biellette est à son tour reliée par une autre articulation à un bras ou triangle de suspension lié au porte-moyeu de la roue, pour suivre les débattements de cette roue lors du travail de la suspension. Les articulations des biellettes permettent de suivre une trajectoire particulière du bras de suspension qui entraîne la biellette. The present invention relates to a filtering anti-roll bar for motor vehicle running gear, and a vehicle equipped with such anti-roll bar. Motor vehicles generally have on the front axle, and in some cases on the rear axle, an anti-roll bar. An anti-roll bar of a known type, described in particular in EP-B1-0631891, has a transverse central portion whose ends are held by bearings connected to the vehicle body, and side portions protruding towards the outside bearings. The lateral parts of the anti-roll bar comprise a bend for producing a lever arm, which terminates in a hinge connected to a link. This link is in turn connected by another joint to an arm or wishbone linked to the hub carrier of the wheel, to follow the movements of this wheel during the work of the suspension. The joints of the rods make it possible to follow a particular trajectory of the suspension arm which drives the rod.
On peut ainsi transmettre par une biellette et ses articulations à la barre anti-devers, un mouvement lié au débattement de la roue qui est transformé par le bras de levier en rotation de la partie transversale autour de son axe. La différence de débattement de chaque roue du même train génère un couple de torsion appliqué entre les deux extrémités de la partie transversale de la barre anti-devers, cette partie transversale agissant comme un ressort travaillant en torsion pour exercer un couple de rappel des suspensions vers une position similaire de deux côtés. On réalise ainsi notamment une réduction de l'inclinaison latérale du véhicule, pour assurer le confort et la tenue de route. It is thus possible to transmit via a link and its joints to the anti-roll bar, a movement related to the displacement of the wheel which is transformed by the lever arm in rotation of the transverse portion about its axis. The difference in displacement of each wheel of the same train generates a torsion torque applied between the two ends of the transverse portion of the anti-roll bar, this transverse part acting as a spring working in torsion to exert a restoring torque of the suspensions towards a similar position on two sides. In particular, a reduction in the lateral inclination of the vehicle is achieved to ensure comfort and handling.
Toutefois, les biellettes reliant la roue à la barre anti-devers étant rigides, les excitations reçues par cette roue et transmises par le porte- moyeu à la biellette, sont à leur tour transmises à la caisse du véhicule par les paliers de la barre anti-devers, ce qui génère du bruit. Ces excitations de la roue peuvent provenir du contact avec les irrégularités de la route lors du roulage. Elles peuvent provenir aussi du train lui-même par le fonctionnement de ses systèmes comme une commande hydraulique, des clapets ou des frottements métalliques, ces excitations du train étant transmises à la roue par les suspensions et le moyeu de la roue. Il est connu pour absorber des vibrations, d'utiliser des batteurs comprenant une masse reliée par une liaison élastique, pouvant absorber des excitations périodiques sur une plage de fréquence réduite, qui est généralement insuffisante. Il est connu aussi pour filtrer des vibrations axiales, d'interposer une matière élastique travaillant en compression entre deux surfaces transversales pour relier deux parties axiales. Ce principe à pour inconvénient de mal résister aux flexions qui peuvent se produire entre ces deux parties axiales. De plus, l'encombrement est important. La présente invention a notamment pour but d'éviter ces inconvénients de la technique antérieure et de proposer une solution simple, compacte et économique pour réduire la transmission à la caisse d'un véhicule, d'une excitation provenant des roues. Elle propose à cet effet une barre anti-devers filtrante pour véhicule automobile, comportant une partie centrale disposée transversalement formant une barre de torsion guidée par deux paliers espacés liés à la caisse du véhicule, chaque extrémité de cette partie centrale étant reliée à un support du moyeu d'une roue par une biellette axiale comprenant des fixations à ses extrémités, caractérisée en ce que les biellettes comportent une liaison élastique reliant leurs fixations, formée d'une partie rectiligne axiale insérée avec un jeu dans une partie tubulaire, ces deux parties étant reliées par une matière élastique. However, since the links connecting the wheel to the anti-roll bar are rigid, the excitations received by this wheel and transmitted by the hub carrier to the rod are in turn transmitted to the vehicle body by the bearings of the anti-roll bar. -devers, which generates noise. These excitations of the wheel can come from the contact with the irregularities of the road during the rolling. They can also come from the train itself by the operation of its systems such as a hydraulic control, valves or metal friction, these excitations of the train being transmitted to the wheel by the suspensions and the hub of the wheel. It is known to absorb vibrations, to use drummers comprising a mass connected by an elastic connection, which can absorb periodic excitations over a reduced frequency range, which is generally insufficient. It is also known for filtering axial vibrations, to interpose an elastic material working in compression between two transverse surfaces to connect two axial parts. This principle has the disadvantage of poorly withstand the bending that can occur between these two axial parts. In addition, the size is important. The present invention is intended to avoid these disadvantages of the prior art and to provide a simple solution, compact and economical to reduce the transmission to the body of a vehicle, a excitation from the wheels. To this end, it proposes a filter anti-roll bar for a motor vehicle, comprising a transversely arranged central part forming a torsion bar guided by two spaced bearings linked to the vehicle body, each end of this central part being connected to a support of the vehicle. hub of a wheel by an axial connecting rod comprising fastenings at its ends, characterized in that the rods comprise an elastic connection connecting their fasteners, formed of an inserted axial rectilinear part with a clearance in a tubular part, these two parts being connected by an elastic material.
Un avantage de la barre anti-devers selon l'invention, est que la liaison élastique des biellettes étant comprise dans une partie tubulaire, elle peut être à la fois simple et solide tout en gardant un encombrement réduit. De plus, la barre anti-devers selon l'invention peut comporter une ou plusieurs des caractéristiques suivantes, qui peuvent être combinées entre elles. Avantageusement, la partie rectiligne axiale et la partie tubulaire ont des sections circulaires constantes. La matière élastique peut remplir le jeu, qui comporte une épaisseur constante. Avantageusement, la longueur axiale de la matière élastique remplissant le jeu, représente plus de trois fois le diamètre de la partie tubulaire. Avantageusement, la matière élastique comporte du caoutchouc. An advantage of the anti-roll bar according to the invention is that the elastic connection of the rods being included in a tubular part, it can be both simple and solid while keeping a small footprint. In addition, the anti-roll bar according to the invention may comprise one or more of the following features, which may be combined with one another. Advantageously, the axial rectilinear part and the tubular part have constant circular sections. The elastic material can fill the game, which has a constant thickness. Advantageously, the axial length of the elastic material filling the game, represents more than three times the diameter of the tubular portion. Advantageously, the elastic material comprises rubber.
Selon une disposition particulière, chaque fixation d'extrémité des biellettes comporte une rotule. Avantageusement, la longueur axiale de la matière élastique remplissant le jeu, représente plus de la moitié de la distance séparant les centres des deux rotules. According to a particular arrangement, each end attachment of the rods comprises a ball joint. Advantageously, the axial length of the elastic material filling the game represents more than half the distance separating the centers of the two ball joints.
Selon une caractéristique particulière de l'invention, la raideur axiale de la biellette filtrante réalise un découplage d'une excitation périodique au dessus d'une fréquence d'environ 100Hz. L'invention comprend aussi un véhicule automobile comportant une barre anti-devers filtrante, caractérisé en ce que cette barre anti-devers est réalisée suivant l'une quelconque des caractéristique précédentes. 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 : - la figure 1 est une vue en perspective d'un berceau avant comprenant une barre anti-devers selon l'art antérieur ; et - la figure 2 est une vue en coupe axiale d'une biellette selon l'invention, présentée de manière schématique. La figure 1 représente un berceau avant 2 fixé sous la caisse d'un véhicule, comportant un triangle de suspension 4 qui en association avec un support 6 guidé par un amortisseur, maintient et guide par deux rotules un porte-moyeu 8 de roue avant. Des arbres de roues 10 transmettent le mouvement du groupe motopropulseur non représenté, aux roues avant motrices. Une commande de direction 12 comportant une crémaillère, permet de diriger les roues avant. Une barre anti-devers 21 comprend une partie centrale transversale 20 légèrement cintrée, qui est fixée près de ses extrémités au berceau 2 par deux paliers espacés 22 réalisant une liaison sans jeu permettant un pivotement suivant un axe transversal. According to a particular characteristic of the invention, the axial stiffness of the filter rod decouples a periodic excitation above a frequency of about 100 Hz. The invention also comprises a motor vehicle comprising a filtering anti-roll bar, characterized in that this anti-roll bar is produced according to any one of the preceding characteristics. The invention will be better understood and other features and advantages will emerge more clearly on reading the following description given by way of example, with reference to the appended drawings in which: FIG. 1 is a perspective view of a front cradle comprising an anti-roll bar according to the prior art; and - Figure 2 is an axial sectional view of a rod according to the invention, shown schematically. Figure 1 shows a front cradle 2 fixed under the body of a vehicle, having a wishbone 4 which in combination with a support 6 guided by a damper, maintains and guides by two ball joints a hub carrier 8 of the front wheel. Wheel shafts 10 transmit the movement of the power train not shown, to the front wheels. A steering control 12 comprising a rack, allows to direct the front wheels. An anti-roll bar 21 comprises a transverse central portion 20 slightly curved, which is fixed near its ends to the cradle 2 by two spaced bearings 22 forming a connection without play allowing pivoting along a transverse axis.
Chaque extrémité de cette partie centrale 20, comporte un coude suivant sensiblement un angle droit, formant un bras de levier qui se termine par une première rotule de liaison 28 fixée à une biellette rigide 24. La biellette rigide 24 disposée sensiblement verticalement, comporte à son autre extrémité une deuxième rotule 26 qui est fixée sur le support d'amortisseur 6. De cette manière, les mouvements verticaux du support d'amortisseur 6 sont transmis par la deuxième rotule 26 à la biellette 24 travaillant en traction ou en compression, qui applique à son tour par la première rotule 28 ce mouvement au bras de levier de la barre anti-devers. Each end of this central portion 20 comprises a bend following substantially a right angle, forming a lever arm which terminates in a first connecting ball 28 fixed to a rigid link 24. The rigid link 24 disposed substantially vertically, comprises at its another end a second ball 26 which is fixed on the damper support 6. In this way, the vertical movements of the damper support 6 are transmitted by the second ball 26 to the rod 24 working in traction or compression, which applies in turn by the first ball 28 this movement to the lever arm of the anti-roll bar.
Quand la suspension opposée impose à l'autre extrémité de la barre anti-devers 21 une position angulaire différente, en prenant appui sur les paliers 22 qui forment des points de réaction, ces mouvements des biellettes 24 génèrent un couple de torsion s'appliquant sur la partie centrale 20 de la barre anti-devers 21. Les paliers 22 subissent des efforts importants qui sont du même ordre de grandeur que ceux transmis pas les biellettes 24, ils possèdent donc une rigidité assez élevée. When the opposite suspension imposes on the other end of the anti-roll bar 21 a different angular position, by bearing on the bearings 22 which form reaction points, these movements of the rods 24 generate a torsion torque applying on the central portion 20 of the anti-roll bar 21. The bearings 22 undergo significant forces which are of the same order of magnitude as those transmitted by the rods 24, they therefore have a fairly high rigidity.
Lors du fonctionnement du véhicule, des excitations, chocs ou vibrations, sont transmises par la roue et son porte moyeu 8 au support d'amortisseur 6, qui les transmet ensuite par la biellette 24 et la barre antidevers 21, aux paliers 22. Ces paliers relativement rigides, transmettent à leur tour ces excitations à la caisse du véhicule, ce qui peut générer du bruit et des vibrations. La figure 2 présente une biellette filtrante 41 comprenant à une extrémité, une première rotule 40 fixée à un tube 42 rectiligne de section circulaire disposé suivant l'axe de cette biellette. A son autre extrémité, la biellette filtrante 41 comprend une deuxième rotule 44 fixée à une barre 46 qui est aussi rectiligne et de section circulaire. La barre 46 est insérée dans le tube 42 avec un jeu radial constant entre les deux, la longueur axiale de recouvrement étant remplie par une matière élastique 48. La longueur axiale de recouvrement des parties des deux pièces insérées l'une dans l'autre, est grande devant le diamètre des sections de manière à limiter les fléchissements de la biellette filtrante 41 sous les contraintes en traction ou compression, et à garder un bon alignement axial du tube 42 et de la barre 46. Avantageusement, cette longueur de recouvrement est supérieure à trois fois le diamètre du tube 42, ce qui donne une bonne stabilité à la biellette filtrante 41. Un deuxième critère pour assurer un bon alignement du tube 42 et de la barre 46, qui peut être appliqué en parallèle avec ce premier critère, consiste à prévoir une longueur de recouvrement supérieure à la moitié de la distance séparant les centres des deux rotules 40, 44. During operation of the vehicle, excitations, shocks or vibrations are transmitted by the wheel and its hub carrier 8 to the shock absorber support 6, which then transmits them through the link 24 and the anti-roll bar 21, to the bearings 22. These bearings relatively stiff, in turn transmit these excitations to the vehicle body, which can generate noise and vibrations. Figure 2 shows a filter rod 41 comprising at one end, a first ball 40 fixed to a straight tube 42 of circular section disposed along the axis of this link. At its other end, the filter rod 41 comprises a second ball 44 fixed to a bar 46 which is also rectilinear and circular in section. The bar 46 is inserted into the tube 42 with a constant radial clearance between the two, the axial length of the covering being filled by an elastic material 48. The axial overlap length of the parts of the two parts inserted into one another, is large in front of the diameter of the sections so as to limit the deflections of the filter rod 41 under the tensile or compressive stresses, and to keep a good axial alignment of the tube 42 and the bar 46. Advantageously, this recovery length is greater to three times the diameter of the tube 42, which gives good stability to the filter rod 41. A second criterion for ensuring proper alignment of the tube 42 and the bar 46, which can be applied in parallel with this first criterion, consists of to provide a recovery length greater than half the distance separating the centers of the two joints 40, 44.
Une épaisseur de matière élastique 48 ainsi que des sections circulaires constantes, permettent d'appliquer sur cette matière élastique une contrainte en cisaillement répartie de manière sensiblement uniforme. La matière élastique 48 peut être un caoutchouc restant collé sur les parois par différents moyens, par exemple par adhésion due à la pression de contact, par un collage ou par un surmoulage directement entre les deux pièces. Cette adhésion doit être suffisamment forte pour éviter un glissement sous l'effet des contraintes axiales qui induisent un travail en cisaillement de la matière élastique 48. La raideur axiale de la biellette filtrante 41, est prévue pour réaliser un découplage des excitations périodiques au dessus d'une fréquence d'environ 100Hz. Cette valeur permet de disposer d'une liaison quasi rigide en statique ou pour les oscillations à basse fréquence correspondant aux fréquences des suspensions du véhicule. De cette manière, la barre anti-devers joue pleinement son rôle de stabilisation du véhicule lors du travail des suspensions. A thickness of elastic material 48 and constant circular sections, allow to apply on this elastic material shear stress distributed substantially uniformly. The elastic material 48 may be a rubber remaining adhered to the walls by various means, for example by adhesion due to the contact pressure, by gluing or overmolding directly between the two parts. This adhesion must be strong enough to prevent slipping under the effect of axial stresses which induce work in shear of the elastic material 48. The axial stiffness of the filter rod 41 is provided to achieve a decoupling of the periodic excitations above a frequency of about 100 Hz. This value makes it possible to have a quasi-rigid link in static or for low frequency oscillations corresponding to the frequencies of the suspensions of the vehicle. In this way, the anti-roll bar fully plays its role of stabilizing the vehicle when working suspensions.
Pour les excitations dynamiques à des fréquences plus élevées, au dessus d'environ 100Hz, la biellette 41 se comporte comme un élément filtrant ne transmettant plus ces excitations à la barre anti-devers, et donc à la caisse du véhicule par les paliers 22. On réduit ainsi une transmission de ces vibrations à la caisse, qui pourrait générer des bruits audibles. For dynamic excitations at higher frequencies, above about 100 Hz, the rod 41 behaves like a filter element no longer transmitting these excitations to the anti-roll bar, and thus to the vehicle body by the bearings 22. This reduces the transmission of these vibrations to the body, which could generate audible noises.
La biellette filtrante 41 étant réalisée avec des composants simples, est économique. Un autre avantage de la biellette filtrante 41 suivant l'invention, est que la partie amortissante étant disposée à l'intérieur du tube 42 de section relativement réduite, on obtient une biellette qui garde un encombrement sensiblement similaire à l'art antérieur. Cette caractéristique permet dans un grand nombre de cas d'échanger les biellettes sans rien modifier d'autre sur le véhicule. En variante, la billette filtrante 41 pourrait ne pas comporter d'articulation à ses extrémités mais seulement des fixations rigides, cette biellette s'interposant dans un ensemble comportant des articulations déportées plus loin. The filter rod 41 being made with simple components, is economical. Another advantage of the filter rod 41 according to the invention is that the damping portion being disposed inside the tube 42 of relatively reduced cross section, a rod is obtained which keeps a bulk substantially similar to the prior art. This feature allows in a large number of cases to exchange the rods without changing anything else on the vehicle. In a variant, the filtering billet 41 may not have any articulation at its ends, but only rigid fasteners, this link being interposed in an assembly comprising articulations further away.
