Abstract

The suspension (1) comprises two symmetrical arms (2) in the same plane connecting the wheel to the bodywork. Each arm has an internally projecting part (12) which enables it to be fixed to a deformable cross member (11). They are each fixed to this cross member by bolts passing through holes (13) in the corresponding arm. Each arm supports a wheel sub-assembly and is connected by an elastic articulation (4) to a vehicle cross member.

Description

La présente invention concerne une suspens ion de roue de véhicule automobile. The present invention relates to a motor vehicle wheel suspension.

Dans la plupart des véhicules actuels, les suspensions de roues sont adaptées à chaque emplacement de roue en fonction de l'environnement de celle-ci. Cela nécessite des types de pièces adaptés à chaque roue, ce qui entraîne des surcoûts aussi bien en production < à cause de la diversité des outillages nécessaires) qu'au stade du développement (en raison de la diversité des pièces). In most current vehicles, the wheel suspensions are adapted to each wheel location depending on the environment thereof. This requires types of parts adapted to each wheel, which leads to additional costs both in production (because of the diversity of tools required) and in the development stage (due to the diversity of parts).

La présente invention résout ce problème en proposant des trains roulants symétriques. The present invention solves this problem by proposing symmetrical running gear.

Plus précisément, l'invention propose une suspension de roue de véhicule automobile, comprenant au moins un bras reliant la roue à la structure du véhicule et qui est caractérisée en ce que le bras présente une symétrie permettant de l'utiliser avec une suspension d'une autre roue du véhicule. More specifically, the invention provides a motor vehicle wheel suspension, comprising at least one arm connecting the wheel to the structure of the vehicle and which is characterized in that the arm has a symmetry allowing it to be used with a suspension of another vehicle wheel.

Le bras de suspension précité est symétrique par rapport à un plan. The aforementioned suspension arm is symmetrical with respect to a plane.

La suspens ion comprend au moins un triangle de suspension dont chacun des deux bras est symétrique par rapport à un plan. The suspension includes at least one suspension triangle, each of the two arms of which is symmetrical with respect to a plane.

Selon une variante de réalisation, la suspension comprend au moins un triangle de suspens ion dont les deux bras sont symétriques l'un de l'autre par rapport à un plan. According to an alternative embodiment, the suspension comprises at least one suspension triangle whose two arms are symmetrical to one another with respect to a plane.

Dans le cas d'une suspension arrière à bras tirés, les deux bras sont identiques et chacun est symétrique par rapport à un plan. In the case of a rear suspension with drawn arms, the two arms are identical and each is symmetrical with respect to a plane.

Les deux bras de cette suspens ion arrière sont reliés par une traverse déformable et présentent chacun une partie permettant de fixer ce bras sur la traverse. The two arms of this rear suspension are connected by a deformable cross-member and each have a part allowing this arm to be fixed on the cross-member.

La fixation de la partie de bras précitée à la traverse déformable s'effectue par au moins un boulon passant à travers un passage correspondant de cette partie de bras, lequel passage est perpendiculaire au plan de symétrie précité et symétrique par rapport à celui-ci.  The aforementioned arm part is fixed to the deformable cross member by at least one bolt passing through a corresponding passage of this arm part, which passage is perpendicular to the above-mentioned plane of symmetry and symmetrical with respect thereto.

L'invention vise également un véhicule automobile équipé de suspens ions de roues dont chacune est telle que définie précédemment. The invention also relates to a motor vehicle equipped with suspensions of wheels, each of which is as defined above.

Avantageusement, au moins certains des éléments constitutifs d'une suspension de roue du véhicule sont les mêmes que ceux des suspensions des autres roues de celui-ci. Advantageously, at least some of the components of a vehicle wheel suspension are the same as those of the suspensions of the other wheels thereof.

L'invention sera mieux comprise et d'autres buts, caractéristiques, détails et avantages de celle-ci apparaîtront plus clairement au cours de la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant plusieurs modes de réalisation de l'invention et dans lesquels

En se reportant aux figures 1 et 2, la référence 1 désigne une suspension d'une roue d'un véhicule automobile, du type à triangle de suspension mécanosoudé, dont chaque bras 2 est relié d'une part à un longeron 3, solidaire de la caisse du véhicule, par l'intermédiaire d'une articulation élastique 4 fixée dans un logement correspondant 5 prévu à l'intérieur du longeron 3 par l'intermédiaire d'une pièce formant entretoise 6, et d'autre part à un boîtier 7 de support d'une rotule 8 d'articulation de la roue correspondante. On notera ici que la pièce formant entretoise 6 est l'un des éléments constitutifs de l'articulation 4. Les articulations élastiques 4 sont fixées dans le prolongement des bras respectifs 2 du triangle de suspens ion 1 par l'intermédiaire d'embouts cylindriques 9 emmanchés à force dans des extrémités tubulaires correspondantes des bras 2. With reference to FIGS. 1 and 2, the reference 1 designates a suspension of a wheel of a motor vehicle, of the type with a mechanically welded suspension triangle, each arm 2 of which is connected on the one hand to a spar 3, integral with the vehicle body, by means of an elastic articulation 4 fixed in a corresponding housing 5 provided inside the spar 3 by means of a piece forming a spacer 6, and on the other hand to a housing 7 for supporting a ball joint 8 of articulation of the corresponding wheel. It will be noted here that the spacer forming part 6 is one of the constituent elements of the articulation 4. The elastic articulations 4 are fixed in the extension of the respective arms 2 of the suspension triangle ion 1 by means of cylindrical end pieces 9 force-fitted into corresponding tubular ends of the arms 2.

Chaque embout 9 se termine par une partie filetée 10 permettant de fixer sur celui-ci l'articulation 4 par l'intermédiaire d'un écrou (non représenté). Chaque pièce formant entretoise 6 est montée dans le logement correspondant 5 du longeron 3 suivant un ajustement serré. De plus, les bras 2 ont leurs extrémités opposées aux embouts 9 encastrées respectivement dans des ouvertures 7a ménagées dans le boîtier de rotule 7.Each end piece 9 ends with a threaded part 10 allowing the articulation 4 to be fixed thereon by means of a nut (not shown). Each piece forming a spacer 6 is mounted in the corresponding housing 5 of the beam 3 according to a tight fit. In addition, the arms 2 have their ends opposite to the end pieces 9 embedded respectively in openings 7a formed in the ball joint housing 7.

Selon l'invention, chaque bras 2 du triangle de suspension 1 présente une symétrie permettant de l'utiliser avec le triangle de suspension d'une autre roue du véhicule. According to the invention, each arm 2 of the suspension triangle 1 has a symmetry allowing it to be used with the suspension triangle of another wheel of the vehicle.

Plus précisément, le bras de suspension 2 est symétrique par rapport à un plan horizontal passant par l'axe brisé A-A' ou
B-B' de l'un des deux bras 2 comme représenté en figure 1, chaque bras 2 présentant deux parties droites raccordées l'une à l'autre par une partie coudée. Bien que les deux bras 2 de cette suspension ne soient pas identiques, ces deux bras peuvent être utilisés aussi bien pour le triangle gauche que le triangle droit. En tout cas, la géométrie du train permet également d'utiliser les mêmes articulations élastiques 4 à l'avant et à l'arrière du triangle.More specifically, the suspension arm 2 is symmetrical with respect to a horizontal plane passing through the broken axis AA 'or
BB 'of one of the two arms 2 as shown in FIG. 1, each arm 2 having two straight parts connected to each other by a bent part. Although the two arms 2 of this suspension are not identical, these two arms can be used both for the left triangle and the right triangle. In any case, the geometry of the train also makes it possible to use the same elastic joints 4 at the front and at the rear of the triangle.

La figure 3 représente une autre forme de réalisation d'un triangle de suspension 1 d'une roue d'un véhicule et dont les deux bras identiques 2 formant triangle isocèle sont symétriques l'un de l'autre par rapport à un plan vertical transversal à l'axe longitudinal du véhicule. Un tel triangle de suspens ion peut être utilisé invariablement comme suspens ion avant droite ou gauche ou suspens ion arrière droite ou gauche comme symbolisé par la flèche arquée F1 en figure 3 qui montre que par simple retournement du triangle de suspension avant ou arrière gauche de 1800 dans un plan horizontal, le triangle peut servir de suspension avant ou arrière droite. Dans le cas d'un train arrière de type pseudo
MacPherson, on peut envisager d'avoir les mêmes triangles à l'arrière et à l'avant, à droite et à gauche, soit quatre triangles identiques.FIG. 3 represents another embodiment of a suspension triangle 1 of a vehicle wheel and the two identical arms 2 of which form an isosceles triangle are symmetrical to each other with respect to a transverse vertical plane to the longitudinal axis of the vehicle. Such a suspension triangle can be invariably used as a right or left front suspension or a right or left rear suspension as symbolized by the arched arrow F1 in Figure 3 which shows that by simply inverting the front or rear left suspension triangle from 1800 in a horizontal plane, the triangle can be used as a front or rear right suspension. In the case of a pseudo type rear axle
MacPherson, we can consider having the same triangles at the back and at the front, right and left, that is to say four identical triangles.

La figure 4 montre encore une autre forme de réalisation d'un triangle de suspension 1 à bras différents 2, mais chacun de ces bras étant symétrique par rapport à un plan horizontal passant à son axe respectif A-A'; B-B'. Cette figure montre également que par simple retournement de 1800 autour d'un axe longitudinal au véhicule comme indiqué par la flèche F2, le triangle de suspension 1 peut être utilisé comme suspension avant gauche ou droite ou comme suspension arrière gauche ou droite. FIG. 4 shows yet another embodiment of a suspension triangle 1 with different arms 2, but each of these arms being symmetrical with respect to a horizontal plane passing through its respective axis AA ′; B-B '. This figure also shows that by simply turning 1800 around a longitudinal axis to the vehicle as indicated by arrow F2, the suspension triangle 1 can be used as a left or right front suspension or as a left or right rear suspension.

Les figures 5 et 6 représentent une suspens ion 1 du type à bras tirés 2 d'un train arrière de véhicule automobile. Chaque bras 2 supporte un sous-ensemble de roue (non représenté) et est relié par une articulation élastique 4 à une traverse (non représentée) du véhicule. Les deux bras 2 de cette suspens ion, moulés en aluminium, sont identiques et chacun est symétrique par rapport à un plan horizontal, c'est-à-dire un plan parallèle au plan de la figure 5 ou un plan perpendiculaire à la figure 6 et contenant l'axe A-A'. Figures 5 and 6 show a suspension ion 1 of the type with arms pulled 2 from a rear axle of a motor vehicle. Each arm 2 supports a wheel sub-assembly (not shown) and is connected by an elastic articulation 4 to a cross member (not shown) of the vehicle. The two arms 2 of this suspension, molded in aluminum, are identical and each is symmetrical with respect to a horizontal plane, that is to say a plane parallel to the plane of Figure 5 or a plane perpendicular to Figure 6 and containing the axis A-A '.

Comme représenté en figure 5, les deux bras 2 sont reliés par une traverse déformable 11, chacun de ces deux bras présentant une partie 12 formant saillie vers l'intérieur du véhicule permettant de fixer ce bras sur la traverse déformable 11. Chaque partie en saillie 12 comporte au moins un passage 13, dans le cas présent au nombre de deux, perpendiculaire au plan de symétrie du bras 2 et symétrique par rapport à ce plan. Les passages 13 font office de trous de passage de boulons (non représentés) de fixation de la traverse déformable 11 aux parties en saillie 12. As shown in FIG. 5, the two arms 2 are connected by a deformable cross member 11, each of these two arms having a part 12 projecting towards the interior of the vehicle making it possible to fix this arm on the deformable cross member 11. Each projecting part 12 has at least one passage 13, in this case two in number, perpendicular to the plane of symmetry of the arm 2 and symmetrical with respect to this plane. The passages 13 act as bolt passage holes (not shown) for fixing the deformable cross member 11 to the projecting parts 12.

Sans sortir du cadre de la présente invention, certains des éléments constitutifs d'une suspension de roue du genre représenté dans l'un des modes de réalisation décrits précédemment sont les mêmes que ceux des suspens ions des autres roues du véhicule. Ainsi, chaque suspension de roue peut comporter un pivot de roue interchangeable 14, tel que représenté en figure 7, avec des fixations symétriques 15, 16 respectivement pour la biellette de direction et l'étrier de frein (non représentés), ou la biellette anti-couple pour un train arrière du type pseudo MacPherson, de tels pivots étant connus en soi. D'autres éléments identiques constitutifs des trains avant ou arrière pourraient être également utilisés pour rendre symétriques les suspens ions et peuvent être constitués par les mêmes éléments porteurs (ressortsamortisseurs) à l'avant et à l'arrière, les mêmes articulations élastiques, etc...  Without departing from the scope of the present invention, some of the components of a wheel suspension of the kind shown in one of the embodiments described above are the same as those of the suspensions of the other wheels of the vehicle. Thus, each wheel suspension can comprise an interchangeable wheel pivot 14, as shown in FIG. 7, with symmetrical fixings 15, 16 respectively for the steering rod and the brake caliper (not shown), or the anti rod -torque for a rear axle of the pseudo MacPherson type, such pivots being known per se. Other identical elements constituting the front or rear axles could also be used to make the suspension lines symmetrical and can be constituted by the same load-bearing elements (shock absorbers) at the front and at the rear, the same elastic joints, etc. ..
