Abstract
Description
La présente invention a essentiellement pour objet un dispositif de suspension de deux roues indépendantes opposées d'un véhicule automobile. The present invention essentially relates to a device for suspending two opposite independent wheels of a motor vehicle.
Elle vise également un véhicule d'un type quelconque équipé de ce dispositif. It also relates to a vehicle of any type equipped with this device.
On connart déjà des dispositifs de suspension comportant, pour contrôler le carrossage de deux roues opposées d'un véhicule, des barres ou analogues reliant entre eux d'une part des éléments transversaux supérieurs de la suspension ou des éléments transversaux inférieurs de ladite suspension. Mais ces barres coulissantes ou articulées constituent des systèmes relativement complexes, coûteux, encombrants, d'une fiabilité douteuse, et assurent rarement la perpendicularité permanente des roues par rapport au sol. There are already known suspension devices comprising, for controlling the camber of two opposite wheels of a vehicle, bars or the like connecting together on the one hand upper transverse elements of the suspension or lower transverse elements of said suspension. But these sliding or articulated bars constitute relatively complex, expensive, bulky systems, of doubtful reliability, and rarely ensure the permanent perpendicularity of the wheels relative to the ground.
Par ailleurs, on connaît, d'après par exemple la demande de brevet française nO 86.05378 une suspension comprenant, pour chacune des deux roues, deux éléments de liaison transversaux, supérieur et inférieur, qui relient, d'une façon articulée, le support de roue à la structure du véhicule, l'un de ces éléments transversaux étant articulé, du côté de son extrémité reliée à la structure du véhicule, sur un axe mobile et déplaçable suivant une direction sensiblement verticale. Furthermore, there is known, for example from French patent application No. 86.05378, a suspension comprising, for each of the two wheels, two transverse connecting elements, upper and lower, which connect, in an articulated manner, the support of wheel to the structure of the vehicle, one of these transverse elements being articulated, on the side of its end connected to the structure of the vehicle, on a movable axis and movable in a substantially vertical direction.
On réalise avec cette suspension une géométrie de triangulation variable à plusieurs positions permettant d'obtenir autant de lois de variations du carrossage de la roue que l'on désire, et cela grâce au déplacement de l'axe mobile précité. With this suspension, a variable triangulation geometry with several positions is obtained, making it possible to obtain as many laws of variations in the camber of the wheel as desired, and this thanks to the displacement of the aforementioned movable axis.
Cependant, le choix de la position de cet axe s'effectue soit à l'initiative du conducteur du véhicule, soit automatiquement. Dans le premier cas, la loi de variation demeure arbitraire et ne peut pas prétendre répondre à des situations de route ou de conduite soudaines et imprévisibles. Dans le second cas, un moyen de commande compliqué agit sur l'axe mobile, en fonction de divers paramètres relatifs aux conditions de déplacement du véhicule. However, the choice of the position of this axis is made either on the initiative of the driver of the vehicle, or automatically. In the first case, the law of variation remains arbitrary and cannot claim to respond to sudden and unpredictable driving or driving situations. In the second case, a complicated control means acts on the movable axis, as a function of various parameters relating to the conditions of movement of the vehicle.
Aussi, la présente invention a pour but de remédier à ces inconvénients en proposant un dispositif de suspension perfectionné qui permet notamment d'automatiser de façon simple la loi de variation de carrossage des roues du véhicule, en assurant une perpendicularité permanente des roues par rapport au sol. Also, the present invention aims to remedy these drawbacks by proposing an improved suspension device which in particular makes it possible to automate in a simple manner the law of variation in the camber of the vehicle wheels, by ensuring permanent perpendicularity of the wheels relative to the ground.
A cet effet, l'invention a pour objet un dispositif de suspension de roues indépendantes pour véhicule automobile, et du type comprenant pour chacune des deux roues, au moins deux éléments de liaison transversaux supérieur et inférieur superposés reliant de façon articulée le support de roue à-la structure du véhicule, caractérisé en ce que l'élément transversal supérieur de chacune des roues est relié à la structure du véhicule par l'intermédiaire d'un bras formant levier avec l'élément transversal inférieur de l'autre roue et s'étendant vers le haut à partir de l'articulation de ce levier sur la structure. To this end, the subject of the invention is a device for suspending independent wheels for a motor vehicle, and of the type comprising for each of the two wheels, at least two superposed upper and lower transverse connecting elements hingedly connecting the wheel support. to the structure of the vehicle, characterized in that the upper transverse element of each of the wheels is connected to the structure of the vehicle by means of an arm forming a lever with the lower transverse element of the other wheel and s 'extending upwards from the articulation of this lever on the structure.
On comprend donc que l'on réalise ainsi un dispositif de suspension comportant des liaisons ou interconnexions croisees et telles que ce dispositif s'adapte immédiatement et automatiquement à un état de route ou une conduite quelconque. It is therefore understood that a suspension device is thus produced comprising cross links or interconnections and such that this device adapts immediately and automatically to any road condition or any type of driving.
Suivant une autre caractéristique de l'invention, l'élément transversal supérieur est constitué par au moins deux tronçons articulés entre eux, et le point d'articulation de ces deux tronçons est relié à la structure du véhicule par une biellette. According to another characteristic of the invention, the upper transverse element consists of at least two sections hinged together, and the point of articulation of these two sections is connected to the structure of the vehicle by a link.
On précisera encore ici que la biellette précitée, tout comme le bras de levier articulé à l'élément transversal supérieur, sont susceptibles d'osciller de part et d'autre d'un plan parallèle au plan longitudinal médian du véhicule. It will also be specified here that the aforementioned link, like the lever arm articulated to the upper transverse element, are liable to oscillate on either side of a plane parallel to the median longitudinal plane of the vehicle.
Selon encore une autre caractéristique de cette invention, les deux bras du levier précité forment entre eux un angle sensiblement égal à 900. According to yet another characteristic of this invention, the two arms of the aforementioned lever form between them an angle substantially equal to 900.

En se reportant à la figure 1, et suivant un premier mode de réalisation, un dispositif de suspension conforme à cette invention comprend essentiellement des éléments transversaux supérieurs 1, 2 respectivement articulés en 5 et 11 sur les supports S1, S2 de deux roues opposées, arrière par exemple, R1 et R2 d'un véhicule, et des éléments transversaux inférieurs 3, 4 respectivement articulés eux aussi en 7 et 10 sur les supports de roue S1 et
Les éléments transversaux inférieurs sont constitués chacun par un levier articulé en 8, 9 sur la structure ou caisse C du véhicule, chaque levier comportant un bras 3b, 4b constituant l'élément transversal inférieur proprement dit, et un autre bras 3a, 4a sur lequel est articulé l'élément transversal supérieur 1, 2.Referring to FIG. 1, and according to a first embodiment, a suspension device according to this invention essentially comprises upper transverse elements 1, 2 respectively articulated at 5 and 11 on the supports S1, S2 of two opposite wheels, rear for example, R1 and R2 of a vehicle, and lower transverse elements 3, 4 respectively also hinged at 7 and 10 on the wheel supports S1 and
The lower transverse elements each consist of a lever articulated at 8, 9 on the structure or body C of the vehicle, each lever comprising an arm 3b, 4b constituting the lower transverse element proper, and another arm 3a, 4a on which is articulated the upper transverse element 1, 2.
Plus précisément, l'élément transversal supérieur 1 est articulé en 6 sur le bras 4a du levier 4, tandis que l'élément supérieur transversal 2 est articulé en 12 sur le bras 3a du levier 3, ces deux bras 3a, 4a s'étendant vers le haut à partir de l'articulation associée 8, 9. More specifically, the upper transverse element 1 is articulated at 6 on the arm 4a of the lever 4, while the upper transverse element 2 is articulated at 12 on the arm 3a of the lever 3, these two arms 3a, 4a extending upwards from the associated joint 8, 9.
En d'autres termes, on se trouve ici en présence d'une connexion croisée des éléments transversaux supérieur et inférieur de la suspension. In other words, we are here in the presence of a cross connection of the upper and lower transverse elements of the suspension.
On remarquera encore ici que les deux bras 3a, 3b ; 4a, 4b des leviers 3 et 4 forment entre eux un angle sensiblement égal à 900 et dont le sommet constitue précisément le point d'articulation 8, 9 sur la caisse C du véhicule. It will also be noted here that the two arms 3a, 3b; 4a, 4b of the levers 3 and 4 form between them an angle substantially equal to 900 and the apex of which constitutes precisely the point of articulation 8, 9 on the body C of the vehicle.
Dans le mode de réalisation visible sur la figure 2 où on a utilisé. les même repères pour désigner les éléments communs avec ceux de la figure 1, les éléments transversaux supérieurs 1 et 2 sont chacun constitués par deux tronçons la, lb et 2a, 2b respectivement, ces deux tronçons comportant un point d'articulation repéré en 13 et 16. In the embodiment visible in Figure 2 where we used. the same references to designate the elements common with those of FIG. 1, the upper transverse elements 1 and 2 are each constituted by two sections 1a, 1b and 2a, 2b respectively, these two sections comprising an articulation point identified at 13 and 16.
A ce point d'articulation est reliée l'extrémité d'une biellette 14, 17 dont l'autre extrémité est articulée en 15, 18 sur la structure ou caisse C du véhicule. At this point of articulation is connected the end of a link 14, 17 whose other end is articulated at 15, 18 on the structure or body C of the vehicle.
On remarquera ici que, lors des divers mouvements de la caisse C, les biellettes 14 et 17, de même que les bras 3a, 4a des leviers 3, 4 oscillent de part et d'autre d'un plan parallèle au plan longitudinal médian P du véhicule. It will be noted here that, during the various movements of the body C, the links 14 and 17, as well as the arms 3a, 4a of the levers 3, 4 oscillate on either side of a plane parallel to the median longitudinal plane P of the vehicle.
Mais, pour une meilleure compréhension de l'invention, on expliquera ci-après brièvement le comportement de la suspension décrite ci-dessus en fonction des positions de la caisse C, et cela en s'aidant plus particulièrement des figures 3 à 5 relatives à la réalisation de la figure 2. However, for a better understanding of the invention, the behavior of the suspension described above as a function of the positions of the body C will be briefly explained below, with the aid more particularly of FIGS. 3 to 5 relating to the realization of figure 2.
Sur la figure 3, où l'on voit la caisse C du véhicule en position abaissée sous l'effet par exemple d'un choc ou d'une charge importante, la rotation du levier 3 se répercute sur l'élément transversal supérieur 2 qui se déplace donc vers l'extérieur du véhicule ce qui assure le maintien de la roue R2 dans une position toujours perpendiculaire au sol A. In FIG. 3, where the body C of the vehicle is seen in the lowered position under the effect for example of a shock or a heavy load, the rotation of the lever 3 is reflected on the upper transverse element 2 which therefore moves towards the outside of the vehicle, which keeps the wheel R2 in a position always perpendicular to the ground A.
Le même phénomène se produit, par effet de symétrie, pour ce qui concerne le levier 4 et l'élément transversal supérieur 1 articulé sur ce levier, de sorte que la roue R1 demeurera toujours elle aussi perpendiculaire au sol A. The same phenomenon occurs, by effect of symmetry, as regards the lever 4 and the upper transverse element 1 articulated on this lever, so that the wheel R1 will also always remain perpendicular to the ground A.
Sur la figure 4, où la caisse C est surélevée par rapport au sol A, on voit que, pour les mêmes raisons que précédemment, la perpendicularité des roues R1 et R2 est bien conservée. In Figure 4, where the body C is raised relative to the ground A, we see that, for the same reasons as above, the perpendicularity of the wheels R1 and R2 is well preserved.
Il en est de même dans le cas d'un débattement dissymétrique des roues R1, R2, ce qui peut se produire par exemple dans un virage, la caisse s'inclinant par rapport au sol comme on le voit sur la figure 5. Pour plus de simplicité, on a représenté ici le sol A en position inclinée. It is the same in the case of an asymmetrical movement of the wheels R1, R2, which can occur for example in a turn, the body tilting relative to the ground as seen in Figure 5. For more for simplicity, the ground A has been shown here in an inclined position.
On remarquera ici que le mode de réalisation de la figure 1, qui constitue une variante simplifiée par rapport à la réalisation de la figure 2, fonctionne exactement de la même manière, la seule différence étant que, sur la figure 1, les éléments transversaux supérieur 1 et 2 constituent chacun un élément unique et que les biellettes 14, 17 sont supprimées. It will be noted here that the embodiment of FIG. 1, which constitutes a simplified variant compared to the embodiment of FIG. 2, works in exactly the same way, the only difference being that, in FIG. 1, the upper transverse elements 1 and 2 each constitute a single element and that the links 14, 17 are deleted.
I1 est à noter ici que les éléments de liaison transversaux supérieur et inférieur 1, 2, 3 et 4 peuvent revêtir une forme appropriée quelconque, et constituer par exemple des triangles, des bielles ou des tiges avec éventuellement des moyens complémentaires pour assurer la stabilité aux forces résultant du freinage ou de l'accélération du véhicule. It should be noted here that the upper and lower transverse connecting elements 1, 2, 3 and 4 can take any suitable shape, and constitute, for example, triangles, connecting rods or rods with possibly additional means to ensure stability to forces resulting from braking or acceleration of the vehicle.
Il faut également préciser que l'effet recherché de maintien de la perpendicularité des roues par rapport au sol peut être obtenu en agissant sur des paramètres tels que la longueur et la dissymétrie des éléments de liaison transversaux, la-position des différents points d'articulation ou la longueur et l'orientation du bras 3a, 4a des leviers 3, 4. A cet égard les paramètres ci-dessus pourront être ajustés de façon à optimiser le comportement de la suspension dans tel ou tel sens. It should also be noted that the desired effect of keeping the wheels perpendicular to the ground can be obtained by acting on parameters such as the length and the asymmetry of the transverse connecting elements, the position of the various points of articulation or the length and orientation of the arm 3a, 4a of the levers 3, 4. In this regard the above parameters can be adjusted so as to optimize the behavior of the suspension in this or that direction.
On a donc réalisé suivant l'invention une suspension à carrossage réel nul, et cela grâce à une interconnexion particulière des éléments constituant cette suspension et qui permet à chaque roue d'ajuster automatiquement elle-même son carrossage, et cela en fonction de la position de la roue opposée. We therefore produced according to the invention a suspension with zero real camber, and this thanks to a particular interconnection of the elements constituting this suspension and which allows each wheel to automatically adjust its camber, and this as a function of the position. of the opposite wheel.
Bien entendu, l'invention n'est nullement limitée aux modes de réalisation décrits et illustrés et qui n'ont été donnés qu'à titre d'exemple. Of course, the invention is in no way limited to the embodiments described and illustrated and which have been given only by way of example.
Au contraire, l'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont effectuées suivant son esprit. On the contrary, the invention includes all the technical equivalents of the means described and their combinations if these are carried out according to the spirit.
