Description

Suspente élastique Pour tubulure d'échappement de véhicule.Elastic hanger For vehicle exhaust manifold.

La présente invention concerne une suspente élasti-  The present invention relates to an elastic hanger

que pour tubulure d'échappement de véhicule, cette suspente étant constituée d'un bloc de matière élastique dans les extrémités duquel sont prévus respectivement un passage de réception d'un crochet courbé de fixation audit véhicule, et un passage de réception d'un crochet courbé de fixation à ladite tubulure, ces crochets étant destinés à traverser  as for vehicle exhaust manifold, this hanger consisting of a block of elastic material in the ends of which are respectively provided a passage for receiving a curved hook for fixing to said vehicle, and a passage for receiving a hook curved for fixing to said tube, these hooks being intended to pass through

ledit bloc.said block.

L'immobilisation du bloc en matière élastique en translation suivant l'axe des crochets est généralement réalisée par des épaulements situés sur l'un des crochets de part et d'autre du bloc Lors d'un montage, on utilise  The immobilization of the block of elastic material in translation along the axis of the hooks is generally carried out by shoulders located on one of the hooks on either side of the block. During assembly, use is made

risques de déchirement du bloc en matière élastique.  risk of tearing of the block of elastic material.

Le but de la présente invention est d'éliminer cet inconvénient et d'empêcher le plus simplement possible le bloc de matière élastique de se déplacer sur les crochets en  The object of the present invention is to eliminate this drawback and to prevent the block of elastic material from moving over the hooks as simply as possible.

translation après le montage.translation after assembly.

A cet effet, une suspente conforme à l'invention du type défini au début est essentiellement caractérisée en ce que l'un desdits crochets présente à son extrémité destinée à traverser ledit bloc lors du montage, au moins un doigt radial propre à coulisser dans une rainure du bloc, lors de ce montage, seulement lorsque ledit bloc est pivoté, autour de l'axe dudit crochet, jusqu'à une position différente de sa position finale, ce doigt empêchant ainsi le bloc de glisser sur le crochet en sens inverse et de s'en échapper  To this end, a hanger according to the invention of the type defined at the start is essentially characterized in that one of said hooks has at its end intended to pass through said block during assembly, at least one radial finger suitable for sliding in a groove of the block, during this assembly, only when said block is pivoted, about the axis of said hook, to a position different from its final position, this finger thus preventing the block from sliding on the hook in the opposite direction and to escape from it

lorsque ledit bloc est ramené dans sa position finale.  when said block is returned to its final position.

De préférence, ladite rainure est pratiquée dans un insert tubulaire occupant le passage correspondant dudit  Preferably, said groove is formed in a tubular insert occupying the corresponding passage of said

moulage, et être maintenu dans ce passage par collage.  molding, and be maintained in this passage by gluing.

Un mode d'exécution de l'invention est décrit ci-  An embodiment of the invention is described below.

dessous à titre d'exemple nullement limitatif, avec référen- ce aux figures du dessin annexé dans lequel: la figure 1 est une vue de face de la suspente;  below by way of nonlimiting example, with reference to the figures of the appended drawing in which: FIG. 1 is a front view of the hanger;

la figure 2 est une vue en coupe par la ligne II-  Figure 2 is a sectional view along line II-

II de la figure 1; et la figure 3 est une vue partielle en coupe selon  II of Figure 1; and Figure 3 is a partial sectional view along

la ligne III-III de la figure 2.line III-III of Figure 2.

Sur les figures on a désigné en 1 le crochet destiné à la fixation de la tubulure d'échappement, et en 7 celui qui est destiné à être fixé sur le véhicule Le bloc de matière élastique (élastomère) constituant le corps de la suspente est référencé en 2 Son élasticité lui est conférée par deux branches 2 a et 2 b raccordant l'une à l'autre deux extrémités massives dans lesquelles sont ménagés les passages respectifs pour les crochets 1 et 7 Le passage du crochet 1 contient un insert en matière synthétique rigide 3 mis en place dans le moule et sur lequel vient donc se  In the figures, the hook intended for fixing the exhaust manifold has been designated at 1, and at 7 the one which is intended to be fixed to the vehicle. The block of elastic material (elastomer) constituting the body of the hanger is referenced in 2 Its elasticity is given to it by two branches 2 a and 2 b connecting one to the other two massive ends in which the respective passages are provided for the hooks 1 and 7 The passage of the hook 1 contains an insert made of synthetic material rigid 3 placed in the mold and on which therefore comes

L'extrémité libre du crochet 1 comporte deux doigts diamétralement opposés 4, de dimensions telles qu'ils puissent coulisser dans les rainures 6 et s'étendant dans un  The free end of the hook 1 comprises two diametrically opposite fingers 4, of dimensions such that they can slide in the grooves 6 and extending in a

plan vertical.vertical plane.

Ceci étant, on voit que le montage du bloc 2 sur le crochet 1 pourra s'effectuer très simplement en faisant pivoter ce bloc de 90 par rapport à sa position normale, ce qui permet d'enfiler le crochet 1 dans l'insert 3 sans  This being the case, it can be seen that the assembly of the block 2 on the hook 1 can be carried out very simply by rotating this block by 90 relative to its normal position, which makes it possible to thread the hook 1 into the insert 3 without

aucun effort, les doigts 4 du crochet se trouvant alors vis-  no effort, the fingers 4 of the hook then being vis-

à-vis des rainures 6 de l'insert.opposite the grooves 6 of the insert.

Lorsque les doigts 4 sont sortis de l'insert 3 on ramène le bloc 2 dans sa position verticale normale, ce qui supprime la coïncidence entre les doigts 4 et les rainures 6, et empêche donc le crochet 1 de ressortir du bloc, les doigts 4 venant alors buter sur l'extrémité de l'insert, comme visible sur la figure 2 Ensuite le bloc 2 peut être  When the fingers 4 are out of the insert 3 the block 2 is brought back to its normal vertical position, which eliminates the coincidence between the fingers 4 and the grooves 6, and therefore prevents the hook 1 from coming out of the block, the fingers 4 then abutting on the end of the insert, as visible in Figure 2 Then the block 2 can be

pondant Il n'y a pas besoin de prévoir de dispositions spéciales à ce niveau, puisque le crochet 1 à lui seul empêche tout déplacement en translation du bloc 2 par  laying There is no need to provide special provisions at this level, since the hook 1 alone prevents any movement in translation of the block 2 by

rapport aux crochets 1 et 7.compared to brackets 1 and 7.

Il est à noter que l'insert 3 peut être collé dans le passage correspondant du bloc 2 Les doigts 4 et rainures 6 sont en nombre quelconque, mais on comprend qu'une ou deux  It should be noted that the insert 3 can be glued in the corresponding passage of the block 2 The fingers 4 and grooves 6 are in any number, but it is understood that one or two

rainures suffisent.grooves are sufficient.

Il va de soi également que le système qui vient d'être décrit pourrait être adopté pour le crochet fixé au châssis en lieu et place du crochet fixé à la tubulure d'échappement.  It goes without saying also that the system which has just been described could be adopted for the hook fixed to the chassis in place of the hook fixed to the exhaust manifold.
