Description

SUPPORT ELASTIQUE A FAIBLE RAIDEUR, NOTAMMENT POUR
l
VEHICULE AUTOMOBILE.LOW-STRAIGHT ELASTIC SUPPORT, ESPECIALLY FOR
l
MOTOR VEHICLE.

La présente invention se rapporte à un support élastique à faible raideur, notamment pour véhicule automobile.The present invention relates to an elastic support with low stiffness, in particular for a motor vehicle.

On connaît déjà des supports elastiques, utilisés en particulier pour suspendre le bloc motopropulseur dans le compartiment correspondant d'un véhicule automobile , ils sont essentiellement constitués d'un bloc de mélange de caoutchouc vulcanisé, de forme parallélépipédique ou cylindrique, adhérisé à deux armatures en acier pourvues de moyens de fixation, respectivement au moteur et à la structure de caisse.Elastic supports are already known, used in particular to suspend the power unit in the corresponding compartment of a motor vehicle, they essentially consist of a block of vulcanized rubber mixture, of parallelepiped or cylindrical shape, adhered to two frames in steel provided with fixing means, respectively to the engine and to the body structure.

De tels supports élastiques travaillent à la fois en compression et en cisaillement, la raideur en compression étant au minimum de trois fois la raideur en cisaillement.Such elastic supports work both in compression and in shear, the stiffness in compression being at least three times the stiffness in shear.

La tendance à un allègement sensible du bloc moteur étant constante, il est alors nécessaire de modifier les supports élastiques en conséquence de façon à optimiser l'atténuation de la transmission des vibrations issues du moteur vers la caisse.Since the tendency to significantly lighten the engine block is constant, it is therefore necessary to modify the elastic supports accordingly so as to optimize the attenuation of the transmission of vibrations from the engine to the body.

A titre d'exemple, il était courant de suspendre un moteur à l'aide d'un nombre de supports tel que la charge supportée par chacun d'entre eux était de l'ordre de 60 kg.For example, it was common to suspend an engine using a number of supports such that the load supported by each of them was of the order of 60 kg.

Les nouveaux moteurs utilisés, très sensiblement allégés, n'imposeraient plus sur lesdits supports que des charges voisines de 40 kg. The new motors used, which are very much lighter, would no longer impose on said supports more than 40 kg.

Si dans ces nouvelles conditions d'utilisation les mêmes supports étaient employés, leurs raideurs deviendraient trop importantes au regard de la charge suspendue, desquelles découlerait une transmission également trop grande des bruits et des efforts dynamiques issus du moteur vers l'habitacle.If in these new conditions of use the same supports were used, their stiffnesses would become too great with regard to the suspended load, from which would result too great a transmission of noise and dynamic forces from the engine to the passenger compartment.

On pourrait envisager d'incliner ces supports par rapport à leur position actuelle selon laquelle ils travaillent pratiquement exclusivement en compression.One could consider tilting these supports from their current position that they work almost exclusively in compression.

Dans ces conditions, on ferait intervenir une plus faible composante de compression et une composante complémentaire de cisaillement, proportionnellement de plus en plus grande1 au fur et à mesure que l'on s'éloignerait angulairement de la position d'origine.Under these conditions, a lower compression component and a complementary shear component would be involved, proportionally greater and greater1 as one moves angularly away from the original position.

Mais du fait même de cette composante de travail en compression du bloc d'élastomère, ce dernier aurait toujours une raideur supérieure à celle que l'on recherche par un travail pratiquement exclusivement en cisaillement ; tel est précisément le but de la présente invention.But by the very fact of this working component in compression of the elastomer block, the latter would always have a stiffness greater than that which is sought by working almost exclusively in shearing; this is precisely the aim of the present invention.

Celle-ci sera décrite de façon non limitative et à titre d'exemple, au-regard des figures 1 à 8 cijointes, qui se rapportent respectivement - la figure 1, à une vue en perspective d'un support

En référence à la figure 1, le support élastique de moteur selon l'état de la technique est essentiellement constitué d'un bloc d'élastomère vulcanisé 1 adhérisé aux armatures métalliques 2 - 3 munies de moyens de fixation respectivement au moteur et au châssis du véhicule. On voit que selon l'orientation du support représentée, le bloc d'élastomère 1 est surtout sollicité en compression selon l'axe Kc, et de ce fait, présente une grande rigidité, de laquelle découlent les inconvénients précédemment évoqués. With reference to FIG. 1, the elastic motor support according to the state of the art essentially consists of a block of vulcanized elastomer 1 adhered to the metal reinforcements 2 - 3 provided with means of fixing respectively to the motor and to the chassis of the vehicle. It can be seen that, depending on the orientation of the support shown, the elastomer block 1 is above all stressed in compression along the axis Kc, and therefore has great rigidity, from which arise the drawbacks mentioned above.

La représentation théorique du support selon l'invention est schématisée à la figure 2 ; on remarque les deux blocs d'élastomères 20 - 21, disposés respectivement dans un plan vertical et horizontal et réunis par l'une de leurs faces au moyen d'une armature rigide 22 présentant une courbure de 90" , leur face opposée comporte chacune une autre armature 23 - 24 et des moyens de fixation au moteur et à la caisse.The theoretical representation of the support according to the invention is shown diagrammatically in FIG. 2; we note the two blocks of elastomers 20 - 21, respectively arranged in a vertical and horizontal plane and joined by one of their faces by means of a rigid frame 22 having a curvature of 90 ", their opposite face each has a another frame 23 - 24 and means for fixing to the engine and to the body.

Selon cette disposition, les efforts verticaux selon Kc du tampon 21, agissant en compression sur le bloc 21, se heurtent à une rigidité supérieure à celle qu'opposerait le bloc 20, agissant en cisaillement ces efforts, transmis par l'armature 22, agiront donc selon Ksl. According to this arrangement, the vertical forces according to Kc of the buffer 21, acting in compression on the block 21, collide with a rigidity greater than that which the block 20 would oppose, acting in shear these forces, transmitted by the frame 22, will act therefore according to Ksl.

De la même façon, les efforts selon Kc2, agissant en compression sur le tampon 20, seront transmis via la structure 22 au tampon 21, qui les prendra en compte, en cisaillement suivant Ks2, du fait de sa plus faible rigidité opposée. On notera que les raideurs en compression des blocs 20 - 21 n'interviennent pratiquement pas.In the same way, the forces according to Kc2, acting in compression on the pad 20, will be transmitted via the structure 22 to the pad 21, which will take them into account, in shear according to Ks2, due to its lower opposite stiffness. It will be noted that the compression stiffnesses of the blocks 20 - 21 are practically not involved.

La pièce illustrée à la figure 3 est un exemple de réalisation de l'invention. Elle comporte trois tubes 30 - 31 - 32 séparés deux à deux par une paire de blocs en caoutchouc vulcanisés, respectivement 33 - 34 et 35 - 36, chacune desdites paires étant décalée de 90" l'une par rapport à l'autre. Les tubes intérieur 30 et extérieur 32 permettent la fixation de l'organe à suspendre au châssis du véhicule, tandis que le tube intermédiaire 31 permet la solidarisation des deux blocs de caoutchouc 33 - 35. Ces deux sous ensembles
30 - 33 et 32 - 35 peuvent être volontairement décen
trés au moment de la fabrication, de façon à se retrou
ver centrés sous charge.The part illustrated in Figure 3 is an exemplary embodiment of the invention. It comprises three tubes 30 - 31 - 32 separated two by two by a pair of vulcanized rubber blocks, respectively 33 - 34 and 35 - 36, each of said pairs being offset by 90 "with respect to each other. inner 30 and outer 32 tubes allow the attachment of the organ to be suspended from the vehicle chassis, while the intermediate tube 31 allows the two rubber blocks 33 - 35 to be joined. These two subassemblies
30 - 33 and 32 - 35 can be voluntarily decen
very at the time of manufacture, so
worms centered under load.

Comme dans le cas théorique illustré à la figure 2, on
remarquera que les efforts dirigés suivant n'importe
lequel des axes X - Y - Z entraînera une déformation des blocs d'élastomère 33 - 35 en cisaillement, pour
les mêmes raisons évoquées précédemment.As in the theoretical case illustrated in Figure 2, we
will notice that the directed efforts following any
which of the axes X - Y - Z will cause a deformation of the elastomer blocks 33 - 35 in shear, for
the same reasons mentioned above.

La figure 4 représente une variante de la figure 3, dans laquelle les armature 40 - 41 - 42 sont adaptées
à l'environnement mécanique du compartiment moteur et,
à titre d'exemple, prennent une section polygonale.FIG. 4 represents a variant of FIG. 3, in which the reinforcements 40 - 41 - 42 are adapted
to the mechanical environment of the engine compartment and,
as an example, take a polygonal section.

Des fonctions supplémentaires peuvent être rapportées
au support de l'invention.Additional functions can be added
in support of the invention.

C'est ainsi que la figure 5 décrit l'association de butées complémentaires au support de la figure 3, permettant ainsi un amortissement progressif des à coups éventuels de couples en provenance du moteur. This is how FIG. 5 describes the association of complementary stops to the support of FIG. 3, thus allowing a progressive damping of the possible blows of torques coming from the engine.

On retrouve les composants déjà évoqués plus haut, à savoir les tubes 30 - 31 - 32 et le-s paires de blocs en caoutchouc 33 - 34 - 35 - 36.We find the components already mentioned above, namely the tubes 30 - 31 - 32 and the pair of rubber blocks 33 - 34 - 35 - 36.

On remarquera, à l'intérieur des cavités délimitées
par les éléments précédents, des butées coniques en
élastomère 50 - 51 et 52 - 53 venues de moulage res
pectivement sur les tubes 31 et 30. Ces butées 50 à 53
peuvent entrer progressivement en action lors des rap
prochements brutaux des tubes 30 à 32. We will notice, inside the delimited cavities
by the previous elements, conical stops in
elastomer 50 - 51 and 52 - 53 res moldings
pectively on tubes 31 and 30. These stops 50 to 53
can gradually come into action during rap
sudden nearness of tubes 30 to 32.

Une autre fonction complémentaire est illustrée à la figure 6, qui dérive également du dispositif de la figure 3. Dans ce support élastique, on remplace le tube médian 31 de la figure 3 par un insert intermédiaire 60, de masse bien déterminée, lui apportant un effet déphasant. Du fait de l'indépendance des raideurs suivant les axes Z et Y, il est possible d'obtenir dans ces directions des fréquences de résonance indépendantes, adaptées et déphasées par rapport aux fréquences de l'environnement mécanique immédiat, de façon à les atténuer sensiblement.Another complementary function is illustrated in FIG. 6, which also derives from the device of FIG. 3. In this elastic support, the median tube 31 of FIG. 3 is replaced by an intermediate insert 60, of well-defined mass, providing it with a phase shifting effect. Due to the independence of the stiffnesses along the Z and Y axes, it is possible to obtain independent resonance frequencies in these directions, adapted and out of phase with the frequencies of the immediate mechanical environment, so as to substantially attenuate them. .

Encore une variante de la présente invention est représentée aux figures 7 et 8 et a pour but d'augmenter l'effet amortissant du support par dissipation d'énergie au moyen d'un liquide visqueux disposé dans ses cavités.Yet another variant of the present invention is shown in Figures 7 and 8 and aims to increase the damping effect of the support by energy dissipation by means of a viscous liquid disposed in its cavities.

Le support est constitué de deux demi-articulations 72 - 73, emmanchées entre un tube extérieur 70 et un tube intérieur 71. The support consists of two half-joints 72 - 73, fitted between an outer tube 70 and an inner tube 71.

A l'état assemblé, le support comporte comme précédemment deux paires de blocs en élastomère 35 - 36 et 33 34, disposées de part et d'autre d'un tube intermédiaire de liaison 79 et décalées de 90 . In the assembled state, the support comprises, as before, two pairs of elastomer blocks 35 - 36 and 33 34, arranged on either side of an intermediate connecting tube 79 and offset by 90.

Toutefois, les cavités -74 - 75 - 76 déterminées par les blocs d'élastomère précédents sont fermées sur les côtés par des cloisons souples telles que 77 - 78 et communiquent entre elles à travers des fentes 80 ménagées à travers le tube intermédiaire de liaison 79 et les blocs 33 - 34. Les cavités telles que 74 et 75 sont pourvues d'un liquide visqueux à caractère amortissant susceptible de se déplacer avec des pertes de charge à travers les fentes 80. However, the cavities -74 - 75 - 76 determined by the preceding elastomer blocks are closed on the sides by flexible partitions such as 77 - 78 and communicate with each other through slots 80 formed through the intermediate connecting tube 79 and the blocks 33 - 34. The cavities such as 74 and 75 are provided with a viscous liquid with a damping character capable of moving with pressure losses through the slots 80.

Naturellement, on ne sortirait pas du domaine de la présente invention, si l'on utilisait en variante un nombre plus important de sous-ensembles tubes 30 - 32 et blocs d'élastomère 33-34, 35-36, de façon à augmenter la raideur du support.Naturally, it would not be departing from the scope of the present invention, if a larger number of tube 30 - 32 and elastomer block 33-34, 35-36 sub-assemblies were used as a variant, so as to increase the stiffness of the support.

La variante décrite à la figure 9 découle de la représentation selon la figure 5.The variant described in FIG. 9 follows from the representation according to FIG. 5.

On retrouve les deux sous-ensembles constitués par les tubes 30-32 et les blocs d'élastomère 33-34 et 3536. Toutefois, les butées coniques en élastomère 50 - 51 sont, dans le cas de la figure 9, remplacées par les éléments 90. Ces derniers dont le volume remplit partiellement ou totalement l'espace disponible entre les blocs d'élastomère 34-35, peut être constitué d'un élastomère de nature et de propriétés différentes de celles des blocs 34 - 35.We find the two sub-assemblies constituted by the tubes 30-32 and the elastomer blocks 33-34 and 3536. However, the conical elastomer stops 50 - 51 are, in the case of FIG. 9, replaced by the elements 90. These latter, the volume of which partially or completely fills the space available between the blocks of elastomer 34-35, may consist of an elastomer of a nature and properties different from those of blocks 34 - 35.

Comme on le voit à la figure 9, une des représentations de l'élément 90 comporte un corps central de préférence de forme adaptée à celle de l'espace disponible où il est introduit, et deux rebords 91 - 92 souples, situés à ses extrémités,déformables, et servant à son maintien en position dans le support. As seen in FIG. 9, one of the representations of the element 90 comprises a central body preferably of a shape adapted to that of the available space into which it is introduced, and two flexible flanges 91 - 92, situated at its ends. , deformable, and used to hold it in position in the support.

Des blocs analogues, non représentés, pourraient également être utilisés de la même façon dans l'autre sous-ensemble, dans l'espace disponible entre les blocs 35 - 36. Similar blocks, not shown, could also be used in the same way in the other sub-assembly, in the space available between the blocks 35 - 36.
