According to the invention, this device comprises: - a hydraulic device (6) making it possible to circulate the liquid from one cylinder (2g) to another (2d) or vice versa; - And a control device (7) of the hydraulic device (6) as a function of predetermined parameters influencing the slope of the vehicle.

Description

1 - Pour s'opposer à l'inclinaison d'un véhicule en virage, on prévoit1 - To oppose the inclination of a vehicle when cornering, it is expected

actuellement une barre anti-roulis qui, par sa raideur, limite les différences de  currently an anti-roll bar which, by its stiffness, limits the differences of

débattement entre les roues gauche et droite.  travel between the left and right wheels.

Cette solution, si elle est peu coûteuse, possède néanmoins deux inconvénients: ) du fait de son élasticité, la barre anti-roulis ne fait que diminuer l'inclinaison du véhicule,  This solution, if it is inexpensive, has two disadvantages:) due to its elasticity, the anti-roll bar only decreases the inclination of the vehicle,

mais ne l'annule pas.but do not cancel it.

2 ) du fait de sa raideur, la barre anti-roulis nuit au confort lorsqu'une roue passe sur un obstacle alors que l'autre n'y passe pas car c'est un cas (très fréquent) o les roues ne débattent  2) because of its stiffness, the anti-roll bar hinders comfort when a wheel passes over an obstacle while the other does not pass because it is a case (very common) o the wheels do not discuss

pas de façon identique.not the same way.

Ces inconvénients sont d'autant plus sensibles sur les véhicules à suspension hydropneumatique o la grande flexibilité de la suspension impose des barres  These disadvantages are all the more noticeable on vehicles with hydropneumatic suspension where the great flexibility of the suspension imposes bars

anti-roulis d'autant plus raides.anti-roll all the more stiff.

2 - La présente invention a pour objet un dispositif anti-roulis qui est destiné à un essieu de véhicule à suspension hydropneumatique comprenant un vérin de suspension associé à chaque roue et au moins un accumulateur à membrane relié à chacun des vérins par une conduite sur laquelle est interposé au moins un amortisseur et caractérisé en ce qu'il comprend: un dispositif hydraulique permettant de faire circuler le liquide d'un vérin à l'autre ou inversement; et un dispositif d'asservissement du dispositif hydraulique en fonction de paramètres prédéterminés  2 - The present invention relates to an anti-roll device which is intended for a vehicle axle with hydropneumatic suspension comprising a suspension cylinder associated with each wheel and at least one membrane accumulator connected to each of the cylinders by a pipe on which is interposed at least one damper and characterized in that it comprises: a hydraulic device for circulating the liquid from one jack to the other or vice versa; and a device for controlling the hydraulic device according to predetermined parameters

influant sur le dévers du véhicule.  affecting the vehicle's cant.

Lorsque le conducteur prend un virage, le dispositif d'asservissement piloté par exemple par la position du volant et la vitesse du véhicule commande le dispositif hydraulique pour faire passer du liquide d'un vérin à l'autre de façon que l'inclinaison du véhicule soit faible, même pratiquement nulle si on le désire La barre anti-roulis, qui ne joue qu'un rôle secondaire, peut être très flexible, de sorte qu'elle ne nuit pas au confort; elle peut même être supprimée. On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation du dispositif anti-roulis selon l'invention, avec référence à la Figure Unique du dessin annexé qui est le schéma d'une suspension hydropneumatique Au dessin, on voit une suspension hydropneumatique pour un essieu de véhicule qui comprend, associé 3 - à chaque roue 1, un vérin de suspension 2 g ou 2 d relié par une conduite 3 g ou 3 d et par un amortisseur  When the driver takes a turn, the servo device controlled for example by the position of the steering wheel and the speed of the vehicle controls the hydraulic device to pass liquid from one jack to the other so that the inclination of the vehicle is low, even virtually zero if desired The anti-roll bar, which plays a minor role, can be very flexible, so it does not affect comfort; it can even be deleted. An embodiment of the anti-roll device according to the invention is described below by way of non-limiting example with reference to the single FIGURE of the attached drawing, which is a diagram of a hydropneumatic suspension. we see a hydropneumatic suspension for a vehicle axle which comprises, associated 3 - each wheel 1, a suspension cylinder 2 g or 2 d connected by a 3 g or 3 d pipe and by a damper

4 g ou 4 d à un accumulateur à membrane 5.  4 g or 4 d to a membrane accumulator 5.

Les deux conduites 3 _q et 3 d sont reliées l'une à l'autre par un dispositif hydraulique 6 permettant de faire circuler le liquide du vérin 2 q au vérin 2 d, ou inversement, donc de créer une différence de pression entre les deux vérins Ce dispositif est piloté par un dispositif d'asservissement 7 qui module la différence de pression entre les vérins  The two lines 3 _q and 3 d are connected to each other by a hydraulic device 6 for circulating the liquid from the jack 2 q to the cylinder 2 d, or vice versa, thus to create a pressure difference between the two cylinders This device is controlled by a servo-control device 7 which modulates the pressure difference between the cylinders

21 et 2 d en fonction de paramètres déterminés.  21 and 2 d according to determined parameters.

Le dispositif hydraulique 6 peut être constitué, par exemple, par une pompe électro-hydraulique à double sens de rotation; le dispositif 7 pilote alors le sens et la vitesse de rotation de la pompe Il peut aussi être constitué par une pompe hydraulique associée à un distributeur permettant de modifier le sens de circulation du liquide ainsi que la différence de pression entre les deux vérins Le dispositif d'asservissement 7, qui peut être un calculateur électronique, peut être commandé par la vitesse du véhicule, l'angle que fait le volant avec sa position en ligne droite, sa vitesse de rotation et son accélération, l'accélération transversale du véhicule mesurée par un capteur, ou les caractéristiques de masse, de géométrie et de comportement du véhicule, mises en mémoire lors de la fabrication Les deux dispositifs 6 et 7 peuvent  The hydraulic device 6 may be constituted, for example, by an electro-hydraulic pump with two directions of rotation; the device 7 then controls the direction and speed of rotation of the pump It can also be constituted by a hydraulic pump associated with a distributor for changing the direction of flow of the liquid and the pressure difference between the two cylinders 7, which can be an electronic computer, can be controlled by the speed of the vehicle, the angle that makes the steering wheel with its position in a straight line, its speed of rotation and its acceleration, the transverse acceleration of the vehicle measured by a sensor, or the characteristics of mass, geometry and behavior of the vehicle, stored during manufacture The two devices 6 and 7 can

être réunis en un seul ensemble.to be united in one set.

La barre anti-roulis normale 8 dont les extrémités sont reliées par des biellettes 9 aux bras support de roue 10, peut être notablement réduite et sa 4 -  The normal anti-roll bar 8, the ends of which are connected by rods 9 to the wheel support arms 10, can be significantly reduced and its 4 -

flexibilité augmentée.increased flexibility.

Il va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre, au contraire, toutes les variantes C'est ainsi que le dispositif anti- roulis est montré appliqué à une suspension comportant un seul accumulateur 5 relié aux deux vérins 2 g et 2 d Mais cette suspension pourrait comporter plusieurs accumulateurs reliés chacun aux deux vérins 2 g et 2 d par l'intermédiaire d'un ou plusieurs groupes d'amortisseurs tels que 4 _, 4 d; dans ce cas, les amortisseurs 4 q et 4 d sont toujours interposés entre les accumulateurs et le dispositif  It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but covers, on the contrary, all variants. Thus, the anti-roll device is shown applied to a suspension comprising a single accumulator 5 connected to the two jacks 2 g and 2 d But this suspension could comprise several accumulators each connected to the two jacks 2 g and 2 d through one or more groups of dampers such as 4, 4 d ; in this case, the dampers 4 q and 4 d are always interposed between the accumulators and the device

hydraulique 6.hydraulic 6.

On ne sortirait pas non plus du cadre de l'invention s'il y avait des amortisseurs supplémentaires au niveau des vérins, disposés par exemple comme les amortisseurs 11 g et 11 d, les amortisseurs 4 _ et 4 d  It would not be beyond the scope of the invention if there were additional dampers at the jacks, arranged for example as the dampers 11 g and 11 d, the dampers 4 _ and 4 d

étant, eux, toujours présents.being, they always present.
