Abstract

The flexible support has a spindle (1) coupled to the casing by branches of a flexible material. Before installing, a pre-stress is created by a compression being exerted between the spindle coating (4) and padding (11) integral with mounting (12). The compression is created by a rigid insert (15) between the spindle coating and padding. The insert partly integrates the mounting threaded on the spindle. The mounting comprises a sheet metal rider (14).

Description

DISPOSITIF DE SUPPORT ELASTIQUE D'UN AXE DANS UNE CAGE FLEXIBLE DEVICE SUPPORT AN AX IN A CAGE
La présente invention concerne un dispositif de support d'un axe dans une cage aux parois de laquelle il est relié par des branches d'un matériau élastique enrobant l'axe, une précontrainte avant montage du dispositif étant créée par une compresion s'exerçant entre l'enrobage dudit axe et un coussin solidaire de ladite cage, et une pièce de montage étant enfilée sur ledit axe. The present invention relates to a device for supporting a shaft in a cage the sides of which it is connected by branches of an elastic material encasing the axis, a preload before mounting of the device being created by a compresion exerted between coating said axis and integral with a cushion of said cage, and a mounting member being threaded on said axis.

Il pourra s'agir de tout dispositif utilisable dans l'industrie, par exemple dans l'industrie automobile, pour relier deux pièces élastiquement l'une à l'autre. It can be any device used in industry, eg in the automotive industry, to connect two parts elastically to each other.

La précontrainte avant montage, c'est-à-dire à l'état libre, desdites branches de matériau élastique, est ordinairement obtenue grâce à une pièce supplémentaire rapportée ou insert, ou par une déformation de la cage. Preload before mounting, that is to say, in the free state, said branches of elastic material is usually obtained by an additional insert or insert, or by a deformation of the cage.

A la figure 1 on a représenté en perspective un dispositif de support élastique connu, comportant un axe 1 et une cage en forme de tronçon tubulaire 2 aux parois de laquelle il est relié par des branches de caoutchouc 3 enrobant l'axe 1, un renflement central 4 à section en arcs de cercle reliant les deux branches 3 l'une à l'autre. In Figure 1 there is shown in perspective a known elastic support device, comprising a shaft 1 and a cage-shaped tubular section 2 to the walls of which it is connected by rubber sticks 3 encasing the axis 1, a bulge 4 in central section circular arcs connecting the two legs 3 to each other. Pour soumettre ces branches 3 à une précontrainte au repos, on force un insert 5 à glisser entre le renflement 4 et la partie de la paroi de la cage 2 qui lui fait face, cet insert étant ici constitué d'une plaque courbe 6 sur la face concave de laquelle est adhérisé un coussin de caoutchouc 7, la plaque 6 etant retenue sur la cage 2 par des pattes pliées 8. To submit the branches 3 to a preload at rest, is forced an insert 5 to slide between the bulging 4 and the part of the wall of the cage 2 which faces it, this insert being here consists of a curved plate 6 of the concave face of which is bonded a rubber pad 7, the plate 6 being held on the stand 2 by folded tongues 8.

Un effet semblable peut etre obtenu avec le montage représenté dans la vue en bout de la figure 2, dans lequel un coussin 9 à cavité intérieure est adhérisé sur la paroi interne de la cage 2. Il suffit alors d'introduire dans cette cavité un insert rigide 10 de volume suffisant pour presser le coussin 9 contre la partie opposée du renflement 4 et soumettre ainsi les branches 3 à la précontrainte voulue à l'état libre. A similar effect can be obtained with the arrangement shown in the end view of Figure 2, wherein a cushion 9 to interior cavity is bonded on the inner wall of the cage 2. It is then sufficient to introduce into the cavity an insert rigid 10 of sufficient volume to press the cushion 9 against the opposite part of the bulge 4 and thereby make the legs 3 to the desired prestressing in the free state.

Ces deux modes de réalisation nécessitent la mise en place supplémentaire d'une pièce, qui s'ajoute à la mise en place de la pièce de montage sur l'axe 1 situé au centre du renflement 4 des bras, d'où reprise obligatoire de la pièce et surcroît de matière. Both embodiments require the additional installation of a room, in addition to the establishment of the mounting part on the axis 1 in the center of the bulge of the arms 4, which compulsory recovery the room and additional material.

Dans la vue semblable de la figure 3 on a montré un autre mode de réalisation qui ne nécessite pas de pièce supplémentaire mais qui nécessite cependant une reprise de la cage pour la déformer. In view similar to Figure 3 there is shown a further embodiment which does not require additional parts but which requires a recovery cage to deform. La cage 2 comportant intérieurement un coussin de caoutchouc plein 11 adhérisé vis-à-vis du renflement 4 des bras, un aplatissement de la cage 2 obtenu par une pression exercée selon la flèche F permet en effet de comprimer encore le renflement 4 et de soumettre les branches 3 à la précontrainte voulue. The cage 2 having therein a solid rubber cushion 11 bonded vis-à-vis the bead 4 of the arms, a flattening of the cage 2 obtained by pressure exerted along the arrow F makes it possible to further compress the bead 4 and submit the legs 3 to the desired prestressing.

Le but de l'invention est de remédier à ces inconvénients de la technique antérieure et d'éliminer l'opération de reprise de la pièce pour soumettre ses branches élastiques à une précontrainte. The object of the invention is to remedy these disadvantages of the prior art and eliminate the coin recovery operation for subjecting its resilient legs pretensioned.

A cet effet, un dispositif de support élastique d'un axe dans une cage du type défini au début est, conformément à la présente invention, caractérisé en ce que ladite compression s'exerçant entre l'enrobage dudit axe et un coussin solidaire de ladite cage est créée par un insert rigide introduit entre ledit enrobage de l'axe et ledit coussin, cet insert faisant partie intégrante de ladite pièce de montage enfilée sur ledit axe. For this purpose, an elastic support device an axis in a cage of the type defined at the beginning is, according to the present invention, characterized in that said compression exerted between the coating of said axis and an integral of said cushion cage is formed by a rigid insert inserted between said coating of the pin and said pad, said insert forming an integral part of said mounting part on said threaded shaft.

Ainsi le montage - inévitable - de ladite pièce de montage sur l'axe opérera simultanément la mise en place de l'insert rigide soumettant les branches élastiques du dispositif à la précontrainte voulue. Thus, the mounting - unavoidable - said mount piece along the axis will operate simultaneously the introduction of the rigid insert subjecting the resilient legs of the device to the desired prestressing.

Un mode d'exécution de l'invention est décrit cidessous à titre d'exemple nullement limitatif avec référence aux autres figures du dessin ci-annexé dans lequel One invention embodiment is described below by way of non-limiting example with reference to the other figures of the attached drawing wherein
- la figure 4 montre en perspective un dispositif conforme à l'invention mais sur lequel l'insert rigide, avec sa pièce de montage, n'a pas encore été mis en place - Figure 4 shows in perspective a device according to the invention but wherein the rigid insert, with its mounting piece, has not yet been established
- la figure 5 montre en perspective une réalisation possible de la pièce de montage avec son insert - Figure 5 shows in perspective a possible embodiment of the mounting part with its insert
- la figure 6 est une vue en coupe transversale du dispositif, au niveau du plan axial de la pièce de montage une fois mise en place sur l'axe ; - Figure 6 is a cross-sectional view of the device, at the axial plane of the mounting part when placed on the axis; et and
- la figure 7 montre en perspective une variante de réalisation de l'insert de la pièce de montage. - Figure 7 shows in perspective an alternative embodiment of the insert of the mounting part.

Sur la figure 4 on a pris les mêmes références que sur la figure 3 de l'art antérieur pour désigner les mêmes parties ou des parties semblables. In Figure 4 we took the same references as in Figure 3 of the prior art to designate the same or similar parts.

A la figure 5 la pièce de montage a été référencée globalement en 12 ; In Figure 5 the mounting part has been referenced generally at 12; elle comporte un tube 13 propre à s engager sur l'axe 1 du dispositif et solidaire d'un cavalier en tôle 14. L'insert est constitué par une patte recourbée 15 du cavalier. it comprises a tube 13 suitable for engaging on the s axis of the device 1 and secured to a jumper plate 14. The insert is constituted by a bent lug 15 of the rider. Lors du montage, de la sorte, l'insert 15 s'introduit entre le coussin 11 adhérisé dans la cage 2 et le renflement 4 entourant l'axe 1, ce qui soumet les branches élastiques 3 à la précontrainte voulue. During assembly, in this way, the insert 15 is introduced between the seat 11 bonded into the cage 2 and the bead 4 surrounding the shaft 1, which subjects the resilient legs 3 to the desired prestressing. La mise en place de l'insert 15 ne nécessite pas d'opération supplémentaire puisqu'elle s'effectue en même temps que l'engagement du tube 13 de la pièce de montage 12 dans l'axe 1 du dispositif. The introduction of the insert 15 does not require additional operation since it is carried along with the engagement of the tube 13 of the mounting part 12 in the axis 1 of the device.

Dans la variante de la figure 7, on a représenté en perspective une pièce de montage 12' également en tôle, l'insert 15' étant constitué ici d'une patte du cavalier 14' pliée plusieurs fois. In the variant of Figure 7, there is shown in perspective a mounting part 12 'also in sheet metal, the insert 15' being constituted by a tab of the rider 14 folded several times. Le nombre de pliages est fonction de l'épaisseur souhaitée pour l'insert. The number of bends is a function of the desired thickness of the insert.

La pièce de montage pourrait également être réalisée en aluminium moulé. The mounting part may also be made of molded aluminum.
