On se réfère à la figure 1; le support hydroélas- Referring to Figure 1; the hydroelastic support
tique comprend deux parties constitutives 1, 2 qui peuvent être raccordées au moteur et au châssis d'un véhicule respectivement. Ces parties constitutives sont raccordées par un bloc bombé 3, 3' formé d'un élastomère. Lors du fonctionnement, les parties constitutives 1, 2 présentent un déplacement relatif suivant l'axe longitudinal X-X' du support. La partie constitutive 2 a une paroi de forme générale tronconique qui facilite le montage du bloc 3' et elle constitue un prolongement d'une partie (la partie supérieure sur le dessin) d'un carter dont l'autre partie (inférieure) est un organe en forme de cuvette 12 ayant une tick comprises two component parts 1, 2 which can be connected to the engine and chassis of a vehicle respectively. These constituent parts are connected by a curved block 3, 3 'formed of an elastomer. During operation, the constituent parts 1, 2 have a relative displacement along the longitudinal axis X-X 'of the support. The constituent part 2 has a wall of generally frustoconical shape which facilitates the assembly of the block 3 'and is an extension of a part (the upper part in the drawing) of a housing whose other part (lower) is a cup-shaped member 12 having a
tige 13 permettant le raccordement au moteur ou au châssis. rod 13 for connection to the engine or chassis.
La partie supérieure du carter supporté entoure un organe formant une cloison, portant la référence générale 5 et The upper part of the supported casing surrounds a member forming a partition, bearing the general reference 5 and
placé perpendiculairement à l'axe longitudinal X-X'. placed perpendicular to the longitudinal axis X-X '.
L'organe 5 formant la cloison comporte un conduit 15 ayant, en plan, la forme d'un anneau interrompu comme représenté par la coupe de la figure 2. Le conduit est délimité par des surfaces respectives de deux organes (6, 7) en forme de grilles qui sont supportés en butée entre The member 5 forming the partition comprises a duct 15 having, in plan, the form of an interrupted ring as represented by the section of FIG. 2. The duct is delimited by respective surfaces of two members (6, 7) in form of grids that are supported in abutment between
les parties supérieure et inférieure 4, 12 du carter. the upper and lower parts 4, 12 of the housing.
Comme décrit plus en détail dans la suite, l'organe formant une cloison comprend un ensemble de filtration qui a un effet d'amortissement sur les vibrations de fréquence élevée (acoustiques) et d'amplitude relativement faible. Le conduit 15 d'autre part a un effet d'amortissement sur les vibrations mécaniques à fréquence relativement faible et As described in more detail below, the partition member includes a filter assembly which has a damping effect on high frequency (acoustic) vibrations of relatively low amplitude. The duct 15 on the other hand has a damping effect on the mechanical vibrations with a relatively low frequency and
d'amplitude plus grande.of greater amplitude.
La surface supérieure de l'organe 5 formant la cloison et la surface interne du bloc 3, 3' délimitent une chambre de "travail" A (aussi appelée chambre "pulsatoire"). Un organe élastique 11, serré autour de sa périphérie entre la partie inférieure 12 du carter et l'organe inférieur 7 à grille, a un profil tel qu'il délimite la paroi inférieure d'une chambre sensiblement annulaire de "dilatation" B (aussi appelée chambre "de compensation"). Un corps d'amortissement sous forme d'une masse 20 est suspendu élastiquement dans la chambre de travail A, suivant l'axe longitudinal X-X', et est destiné à résonner à une fréquence voulue. De cette manière, la masse 20 a un The upper surface of the member 5 forming the partition and the inner surface of the block 3, 3 'delimit a "working" chamber A (also called "pulsating" chamber). An elastic member 11, clamped around its periphery between the lower portion 12 of the housing and the lower member 7 with a grid, has a profile such that it delimits the bottom wall of a substantially annular chamber of "expansion" B (also called "clearing house"). A cushioning body in the form of a mass 20 is resiliently suspended in the working chamber A, along the longitudinal axis X-X ', and is intended to resonate at a desired frequency. In this way, the mass 20 has a

quence égale à la fréquence de résonance ou voisine de celle-ci. Le bloc bombé 3, 3' qui a une structure feuilletée, est muni (entre ses couches) d'un organe rapporté tronco- quence equal to or near the resonance frequency. The domed block 3, 3 ', which has a laminated structure, is provided (between its layers) with a truncated bearing member

tains intervalles (ou dans une variante de façon continue) tout autour du bord périphérique interne. La configuration sertie est efficace pour la retenue d'un élément de support constitué par un disque 22 ayant une ouverture (par exemple formée par poinçonnage) et qui est raccordé à la masse 20 par un organe élastique de couplage 21. Le disque ayant une ouverture est destiné à positionner la masse 20 au centre de la chambre de travail A et ne gêne pas excessivement le intervals (or in a variant continuously) all around the inner peripheral edge. The crimp configuration is effective for retaining a support member consisting of a disc 22 having an opening (eg formed by punching) and which is connected to the ground 20 by a resilient coupling member 21. The disc having an opening is intended to position the mass 20 in the center of the working chamber A and does not hinder excessively the

Ainsi, du fluide hydraulique peut circuler entre les deux chambres A et B par l'intermédiaire du conduit lors du Thus, hydraulic fluid can flow between the two chambers A and B via the conduit during the

L'amplitude du passage du fluide entre les deux chambres détermine la caractéristique du support hydroélastique aux The amplitude of the passage of the fluid between the two chambers determines the characteristic of the hydroelastic support to

A cet égard, la longueur et la section du conduit déterminent sa fréquence de résonance. En présence de vibrations mécaniques à la fréquence de résonance ou à son voisinage, le conduit empêche le déplacement du fluide entre les chambres ou le limite au moins, et a ainsi un In this respect, the length and section of the duct determine its resonant frequency. In the presence of mechanical vibrations at or near the resonant frequency, the conduit prevents fluid movement between the chambers or the at least one boundary, and thus has a

A cet effet, l'organe formant une cloison a plusieurs trous débouchants, placés entre les chambres de travail et de dilatation, et chaque trou débouchant a une configuration telle qu'il peut positionner et loger un élément respectif d'amortissement sous forme d'une sphère 9 ayant un diamètre juste inférieur à celui du trou débouchant. Les sphères 9 sont formées d'un matériau ayant la même masse volumique que le fluide hydraulique présent dans les chambres A et B ou une masse on (acoustic) vibrations of high frequency and relatively low amplitude. For this purpose, the member forming a partition has a plurality of through holes, placed between the working and expansion chambers, and each opening hole has a configuration such that it can position and house a respective damping element in the form of a sphere 9 having a diameter just smaller than that of the opening hole. The spheres 9 are formed of a material having the same density as the hydraulic fluid present in the chambers A and B or a mass

Les trous débouchants sont délimités par des matrices respectives de trous formés dans les organes supérieur et inférieur 6, 7 à grilles et qui ont des The through holes are delimited by respective dies of holes formed in the upper and lower bodies 6, 7 with grids and which have

Chaque sphère est libre de se déplacer suivant l'axe dans le trou débouchant respectif lors d'un changement de la différence de pression de part et d'autre de l'organe formant la cloison.

Comme chaque sphère de l'ensemble d'amortissement est individuellement au contact d'une surface respective de butée pendant le fonctionnement, l'ensemble ne crée pas de manière importante le bruit indésirable de "claquement" qui peut apparaître pendant le fonctionnement des ensembles de high frequency and relatively low amplitude vibrations and reduces the dynamic rigidity of the hydroelastic support in the high frequency range. Since each sphere of the damping assembly is individually in contact with a respective abutment surface during operation, the assembly does not significantly create the unwanted "snap" noise that may occur during the operation of the arrays.

Il comporte un organe supérieur 17 et un organe inférieur 18 formant des grilles qui délimitent un boîtier pour un organe mobile sous forme d'une rondelle 8 formée d'un élastomère. La rondelle est libre de présenter un faible déplacement axial (par exemple de l'ordre de quelques dixièmes de millimètre) dans le boîtier et a donc un effet d'amortissement sur les It has a member 5 forming a partition which comprises a filtering or damping assembly. It comprises an upper member 17 and a lower member 18 forming grids which define a housing for a movable member in the form of a washer 8 formed of an elastomer. The washer is free to have a small axial displacement (for example of the order of a few tenths of a millimeter) in the housing and therefore has a damping effect on the
vibrations à fréquence relativement élevée (acoustiques). relatively high frequency vibrations (acoustic).
Cependant, un organe de déplacement de ce type a tendance à créer un bruit indésirable de "claquement", essentiellement à l'extrémité des basses fréquences de la caractéristique de réponse et, pour réduire cet effet, la masse 20 (qui ne crée pas un tel bruit de "claquement") peut être montée afin qu'elle résonne dans la même plage de fréquences. Bien entendu, diverses modifications peuvent être apportées par l'homme de l'art aux supports hydroélastiques qui viennent d'être décrits uniquement à titre d'exemples However, a displacement member of this type tends to create an unwanted "click" noise, essentially at the low end of the response characteristic and, to reduce this effect, the mass (which does not create a such "click sound") can be mounted to sound in the same frequency range. Of course, various modifications may be made by those skilled in the art to hydroelastic supports which have just been described as examples only.
