La fabrication d'un support de ce genre est couteuse et peut entraner des defauts d'etancheite au Technical Field of Itinvention The present invention relates to a rubber support with hydraulic damping, comprising an internal fixing piece, an external fixing piece, an elastomer body placed between said fixing pieces and two liquid chambers which communicate through a liquid i5 channel. State of the tenique From the document DE 40 15 523 C1, there is known a rubber support with hydraulic damping in which the elastomer body is provided with at least three axially separated parts, one from the other which extend radially outward and delimit the liquid chambers together with an element placed in a sealed manner, the elastomer body and the annular element being held together under stress and in a pressure-tight manner by the 'intermediate of a tubular fixing piece. The manufacture of a support of this kind is expensive and can cause leaks in the

En outre, ce support doit Presentafion de l'irvenfion The problem at the basis of the present invention consists in producing a rubber support with hydraulic damping, the construction of which is simple, which is easy to manufacture and which has a long service life. In addition, this support must

Etant donne un support en caoutchouc de ltespece susvisee, ce probleme est resolu par les caracteristiques de la revendication 1. Les chambres de liquide o vent disposees a l'interieur du corps en elastomere et le canal de liquide est realise au niveau d'un element de paroi d'une chambre de liquide. Ainsi realise, le support en caoutchouc requiert un minimum de pieces detachees. II est des lors facile a fabriquer et des pieces speciales en materiaux differents ne vent pas necessaires. Les parties qui stetirent radialement delimitent la chambre conjointement avec la paroi intermediaire. Le canal de fluide est forme par au moins un element de paroi de la chambre de iiquide et des parties de ltelement Given a rubber support of the aforementioned species, this problem is solved by the characteristics of claim 1. The liquid chambers are arranged inside the elastomer body and the liquid channel is formed at an element wall of a liquid chamber. Thus produced, the rubber support requires a minimum of spare parts. It is therefore easy to manufacture and special parts made of different materials are not necessary. The parts which extend radially delimit the chamber jointly with the intermediate wall. The fluid channel is formed by at least one wall element of the liquid chamber and parts of the element.

Le support hydraulique en caoutchouc sert surtout a amortir les chocs axiaux. The hydraulic rubber support is mainly used to absorb axial shocks.
Dans un perfectionnement du principe de ['invention, pour absorber les contraintes radiales, un support en caoutchouc est place lateralement a cote des chambres de liquide sur la piece de fixation interieure, ledit support etant entoure d'un propre coussinet exterieur. Le support en caoutchouc peut etre o realise a trots couches et se composer d'une couche de caoutchouc interieure, d'un manchon intermediaire et d'une couche de caoutchouc exterieure. Cette construction offre une bonne possibilite de reglage de la rigidite et de l'amortissement voulus. Le coussinet entourant le support en caoutchouc est pourvu d'une collerette pouvant etre prise par le bord annulaire rabattu de la piece de fixation exterieure, de sorte que le support hydraulique en caoutchouc et le support en caoutchouc a action radiale vent reunis pour former une unite compacte. DescrJption resumee du dessn On va decrire ['invention plus en detail en se referent a un exemple de realisation de celle-ci et au dessin dans lequel In an improvement of the principle of the invention, to absorb the radial stresses, a rubber support is placed laterally next to the liquid chambers on the interior fastening piece, said support being surrounded by its own external cushion. The rubber support can be made in three layers and consist of an inner rubber layer, an intermediate sleeve and an outer rubber layer. This construction offers a good possibility of adjusting the desired stiffness and damping. The cushion surrounding the rubber support is provided with a flange which can be taken up by the folded annular edge of the external fixing piece, so that the hydraulic rubber support and the radial action rubber support are brought together to form a unit. compact. DescrJption summarye du dessn We will describe the invention in more detail with reference to an exemplary embodiment thereof and the drawing in which

The elastomer body 4 makes it possible to form two liquid chambers 5 and 6 connected by the liquid channel 7 and corresponding recesses 8 in the associated external wall element 9 as well as recesses 10 in the central wall element 11. The body in elastomer 4 is formed by the trots of wall elements 9, 11 and 12 placed side by side in the axial direction and which move away radially from the internal fixing piece 2. The elastomer body 4 and the wall elements 9, 11 and 12, on the one hand, and the interior fixing piece 2, on the other hand, wind assembled by

The central wall element 11 is placed at the level of the annular flange 15 of the fixing part or interior 2. The two elements of axially outer wall 9 and 12 wind pressed with their radially outer edges against the central wall element 11, so that the chambers 5 and 6 are closed towards the outside. This pressure 2840042 is effected by means of the external fixing piece 3 in the shape of a bell, the annular edges 16 and 17 of which press the edges of the external wall elements 9 and 12 against the central wall element 11, I fastening element 3 at the same time forming the outer wall of the liquid channel 7. In addition, the fastening part 3 is compressed in its central part 18 so that it is firmly pressed against the central wall element 11 in the radial direction, said wall element 11 thus undergoing a radial prestress. The central part 18 is not pressed into the part of the recess 10 at the level of the central border element 11 only, to avoid reducing the recess 10 o The wall element 12 is provided with the liquid filling cage 19 allowing the chamber 5 to be filled with liquid as well as from the
