A damping ring (7) between the collet and spring dampens loads exerted by the spring. The damping ring is attached to the collet by adhesive or mechanical fixing.

Description

L'invention se rapporte un dispositif de support supérieur pour ressort de suspension, notamment automobile. The invention relates to an upper support device for a suspension spring, in particular an automobile.

L'invention s'applique de préférence à un support supérieur pour ressort de suspension arrière de véhicule automobile. The invention preferably applies to an upper support for a rear suspension spring of a motor vehicle.

Les figure 1 et 2 illustrent un support supérieur de type connu, pour ressort de suspension arrière d'un véhicule automobile. Le support est constitué d'une coupelle 11 en élastomère vulcanisé ayant une forme générale cylindrique. Le bord supérieur de la coupelle 11 est plié à 90 degrés environ vers l'extérieur, de façon à former un rebord 12 circulaire. La coupelle 11 est conformée pour s'emboîter sur une paroi 13 convexe de la structure du véhicule ou du mécanisme de suspension. A cet effet, la coupelle 11 comporte, au niveau de sa paroi constituant le fond de la coupelle, un crochet élastique 14 apte à venir se clipper dans une ouverture formée dans la paroi support 13. La spire de l'extrémité supérieure du ressort 25 vient s'appuyer quant à elle sur la face inférieure de la coupelle 11, au niveau de l'angle formé par le rebord 12. Figures 1 and 2 illustrate an upper support of known type, for rear suspension spring of a motor vehicle. The support consists of a cup 11 of vulcanized elastomer having a generally cylindrical shape. The upper edge of the cup 11 is folded about 90 degrees outward, so as to form a circular rim 12. The cup 11 is shaped to fit onto a convex wall 13 of the structure of the vehicle or of the suspension mechanism. To this end, the cup 11 comprises, at its wall constituting the bottom of the cup, an elastic hook 14 capable of being clipped into an opening formed in the support wall 13. The turn of the upper end of the spring 25 comes to rest on the underside of the cup 11, at the angle formed by the rim 12.

Cependant, ce type de support présente de nombreux inconvénients. Ainsi, compte tenu de la souplesse de la coupelle, le positionnement précis de cette dernière sur la structure s'avère difficile, notamment lorsque la structure support 13 a une forme qui diffère légèrement de sa forme théorique. C'est-à-dire que, lorsque la structure 13 est dissymétrique ou déformée, la forme de la coupelle 11 doit être adaptée en conséquence (référence 30, figure 2). However, this type of support has many disadvantages. Thus, given the flexibility of the cup, the precise positioning of the latter on the structure is difficult, especially when the support structure 13 has a shape which differs slightly from its theoretical shape. In other words, when the structure 13 is asymmetrical or deformed, the shape of the cup 11 must be adapted accordingly (reference 30, FIG. 2).

Par ailleurs, on a constaté que le crochet de clippage 14 en élastomère vulcanisé de la coupelle 11 n'assure pas une fixation fiable de cette dernière sur le support 13. Furthermore, it has been found that the clipping hook 14 made of vulcanized elastomer of the cup 11 does not ensure reliable fixing of the latter on the support 13.

Un but de la présente invention est de proposer un dispositif de support supérieur pour ressort de suspension, notamment automobile, palliant tout ou partie des inconvénients de l'art antérieur relevés ci-dessus. Ce but est atteint par le fait que le dispositif support supérieur pour ressort de suspension, notamment automobile, comporte une coupelle rigide conformée pour, d'une part être disposée contre un support de la structure du véhicule ou du mécanisme de suspension et, d'autre part, accueillir la spire supérieure du ressort, la coupelle comportant des moyens de fixation sur le support et/ou sur le ressort, dispositif comportant également des moyens d'amortissement des efforts transmis par le ressort, les moyens d'amortissement étant rendus solidaires de la coupelle par un accrochage chimique et/ou mécanique. An object of the present invention is to provide an upper support device for a suspension spring, in particular an automobile, overcoming all or part of the drawbacks of the prior art noted above. This object is achieved by the fact that the upper support device for a suspension spring, in particular an automobile, comprises a rigid cup shaped to, on the one hand, be placed against a support of the structure of the vehicle or of the suspension mechanism and, on the other hand, receiving the upper turn of the spring, the cup comprising means for fixing to the support and / or to the spring, device also comprising means for damping the forces transmitted by the spring, the damping means being made integral of the cup by chemical and / or mechanical attachment.

L'invention va à présent être décrite en référence aux figures 3 à 5. The invention will now be described with reference to FIGS. 3 to 5.

Le dispositif de support selon l'invention comporte une coupelle rigide 1 ayant une forme générale cylindrique. Le bord supérieur de la coupelle 1 est plié vers l'extérieur à 90 degrés environ de façon à constituer un épaulement radial 8. The support device according to the invention comprises a rigid cup 1 having a generally cylindrical shape. The upper edge of the cup 1 is folded outwards at approximately 90 degrees so as to form a radial shoulder 8.

La concavité de la coupelle 1 est conformée pour s'emboîter sur une convexité complémentaire d'un support 2 constitué, par exemple, d'une paroi de la structure du vehicule ou du mécanisme de suspension. En position montée, l'épaulement radial 8 repose sur une portion plane du support 2. The concavity of the cup 1 is shaped to fit onto a complementary convexity of a support 2 consisting, for example, of a wall of the structure of the vehicle or of the suspension mechanism. In the mounted position, the radial shoulder 8 rests on a flat portion of the support 2.

La coupelle 1 est fixée sur le support 2 au moyen, par exemple, de trois crochets élastiques 4 situés dans la paroi constituant le fond de la coupelle. Les trois crochets 4 sont agencés de façon à venir s'engager dans une ouverture formée dans le support 2. The cup 1 is fixed to the support 2 by means, for example, of three elastic hooks 4 located in the wall constituting the bottom of the cup. The three hooks 4 are arranged so as to come to engage in an opening formed in the support 2.

La face inférieure de la coupelle 1, qui constitue la surface d'appui pour la spire supérieure du ressort 3, comporte des moyens d'amortissement 7 des efforts transmis par le ressort 3. De préférence, les moyens d'amortissement sont constitués d'une couche 7 d'un matériau souple, tel qu'un élastomère. C'est à dire que la couche d'élastomère souple 7 est rendue solidaire de la surface inférieure de l'épaulement 8 et de la surface cylindrique adjacente de la coupelle 1. Ainsi, la spire inférieure 3 du ressort repose sur la couche souple 7. La couche souple 7 peut être rendue solidaire de la coupelle 1 par un accrochage chimique et/ou mécanique. The underside of the cup 1, which constitutes the bearing surface for the upper turn of the spring 3, comprises damping means 7 for the forces transmitted by the spring 3. Preferably, the damping means consist of a layer 7 of a flexible material, such as an elastomer. That is, the flexible elastomer layer 7 is made integral with the lower surface of the shoulder 8 and the adjacent cylindrical surface of the cup 1. Thus, the lower coil 3 of the spring rests on the flexible layer 7 The flexible layer 7 can be made integral with the cup 1 by chemical and / or mechanical attachment.

Par exemple, l'ensemble constitué par la coupelle et les moyens d'amortissement 7 peut être moulé en une seule opération. C'est-à-dire que la coupelle 1 et la couche souple 7 peuvent être moulés simultanément par injection bi-matière. La coupelle 1 peut ainsi être constituée d'un matériau thermoplastique rigide tel que du Polypropylène chargé à 30% de fibres de verre, les moyens d'amortissement 7 étant constitués quant à eux d'un matériau du type thermoplastique élastomère souple tel que du "SEBS 70 Shores A". For example, the assembly constituted by the cup and the damping means 7 can be molded in a single operation. That is to say that the cup 1 and the flexible layer 7 can be molded simultaneously by bi-material injection. The cup 1 can thus be made of a rigid thermoplastic material such as Polypropylene loaded with 30% glass fibers, the damping means 7 being made up of a material of the flexible elastomeric thermoplastic type such as " SEBS 70 Shores A ".

Bien entendu, l'invention ne sauiait se limiter à l'exemple de réalisation préféré décrit ci-dessus. Ainsi, en variante, la coupelle 1 peut être constituée d'un matériau thermoplastique rigide moulé par injection tel que du Polyamide 6.6 chargé à 25% de fibres de verre, tandis que les moyens d'amortissement 7 sont surmoulés sur la coupelle rigide 1. Dans ce cas, les moyens d'amortissement 7 peuvent être constitués d'un élastomère vulcanisé ou non tel du caoutchouc naturel. Of course, the invention should not be limited to the preferred embodiment described above. Thus, as a variant, the cup 1 can be made of a rigid thermoplastic injection molded material such as Polyamide 6.6 loaded with 25% glass fibers, while the damping means 7 are overmolded on the rigid cup 1. In this case, the damping means 7 may consist of a vulcanized elastomer or not such as natural rubber.

On notera que les moyens de clippage 4 (crochets élastiques) sont moulés d'une pièce avec la coupelle 1. It will be noted that the clipping means 4 (elastic hooks) are molded in one piece with the cup 1.

Les figures 6 à 8 illustrent une variante de réalisation de l'invention. Les éléments identiques à ceux décrits ci-dessus sont désignés par les mêmes références numériques. Figures 6 to 8 illustrate an alternative embodiment of the invention. Elements identical to those described above are designated by the same reference numerals.

Le dispositif de support pour ressort des figures à 8 diffère celui décrit en référence aux figures 3 à 5 le fait qu'il ne comporte pas des moyens de fixation sur la paroi 13. En revanche, dispositif de support des figures 6 à 8 comporte des moyens d'accrochage 9 sur le ressort 3. The spring support device in Figures 8 differs from that described with reference to Figures 3 to 5 the fact that it does not include fixing means on the wall 13. On the other hand, the support device in Figures 6 to 8 comprises attachment means 9 on the spring 3.

Comme représenté aux figures 6 à 8, moyens d'accrochage sont constitués de trois pattes de maintien 9 qui s'étendent sensiblement perpendiculairement de la surface périphérique cylindrique de la coupelle 1. Les trois pattes de maintien sont situés à 90 degrés environ l'une de l'autre, par rapport l'axe de symétrie longitudinal de la coupelle 1. As shown in Figures 6 to 8, hooking means consist of three retaining tabs 9 which extend substantially perpendicularly from the cylindrical peripheral surface of the cup 1. The three retaining tabs are located approximately 90 degrees one on the other, relative to the longitudinal axis of symmetry of the cup 1.

Chacune des pattes de maintien 9 définit, avec l'épaulement radial 8 un logement apte à accueillir et maintenir une partie de la spire inférieure du ressort 3. C'est-à-dire que la spire inférieure est maintenue entre, d'une part l'épaulement radial 8 de la coupelle et, d'autre part, les pattes de maintien 9. Each of the retaining lugs 9 defines, with the radial shoulder 8 a housing capable of receiving and maintaining a part of the lower turn of the spring 3. That is to say that the lower turn is held between, on the one hand the radial shoulder 8 of the cup and, on the other hand, the retaining tabs 9.

Par ailleurs, la face inférieure de l'épaulement radial 8 peut comporter une butée 15 prévue pour empêcher la rotation de l'extrémité du ressort 3 autour de l'axe longitudinal du ressort. Furthermore, the underside of the radial shoulder 8 may include a stop 15 provided to prevent rotation of the end of the spring 3 around the longitudinal axis of the spring.

Le mode de réalisation des figures 6 8 peut être constitué des mêmes matériaux que ceux décrits ci-dessus en référence aux figures 3 à 5. Par ailleurs, les mêmes procédés de fabrication peuvent être utilisés. Ainsi, pattes de maintien 9 et les moyens de butée 15 peuvent être moulés d'une pièce avec les moyens d'amortissement 7. The embodiment of Figures 6 8 can be made of the same materials as those described above with reference to Figures 3 to 5. Furthermore, the same manufacturing methods can be used. Thus, the holding tabs 9 and the stop means 15 can be molded in one piece with the damping means 7.

On conçoit donc aisément que le dispositif de support selon l'invention, tout en étant de structure simple et peu coûteuse permet d'assurer un maintien sûr de l'extrémité supérieure du ressort de suspension. It is therefore easy to see that the support device according to the invention, while being simple and inexpensive in structure, makes it possible to secure the upper end of the suspension spring securely.

Bien entendu d'autres variantes de réalisation de l'invention peuvent être envisagées. Ainsi, on peut envisager une coupelle support comportant à la fois des moyens de fixation la structure ainsi que des moyens d'accrochage sur le ressort. Of course, other alternative embodiments of the invention can be envisaged. Thus, it is possible to envisage a support cup comprising both means for fixing the structure as well as means for hooking onto the spring.

Enfin bien que l'invention ait été décrite en liaison avec des modes de réalisation particuliers, elle comprend tous les équivalents techniques des moyens décrits.Finally, although the invention has been described in connection with particular embodiments, it includes all the technical equivalents of the means described.
