A simplified assembly is thus obtained whilst eliminating the noisiness generated by rubbing.

Description

Coupelle d'appui pour ressort hélicoïdal de suspension de véhicule et suspension de véhicule comportant une telle coupelle.Support cup for coil spring for vehicle suspension and vehicle suspension comprising such a cup.

L'invention concerne essentiellement une coupelle d'appui pour ressort hélicoïdal de suspension de véhicule et une suspension de véhicule comportant une telle coupelle. The invention relates essentially to a support cup for a helical spring for vehicle suspension and to a vehicle suspension comprising such a cup.

Les ressorts métalliques de suspension de véhicule sont généralement montés entre deux pièces en tôle emboutie dites "coupelles d'appui". L'appui du ressort sur ses coupelles se fait par l'intermédiaire des spires d'extrémité dudit ressort qui, au cours du débattement de la suspension, sont en contact sur une partie plus ou moins longue de ladite coupelle. The metal vehicle suspension springs are generally mounted between two pieces of stamped sheet metal called "support cups". The support of the spring on its cups is done by means of the end turns of said spring which, during the movement of the suspension, are in contact on a more or less long part of said cup.

Ces variations de contact entre ressort et coupelle engendrent des bruyances qui sont néfastes du point de vue confort et du point de vue durée de vie du ressort comme de la coupelle métallique. These variations in contact between spring and cup generate noises which are harmful from the comfort point of view and from the point of view of the life of the spring as of the metal cup.

Pour tenter de remédier à ces inconvénients, on a proposé différentes solutions, à savoir a) la première solution consiste à interposer entre le ressort et
la coupelle en tôle emboutie un intercalaire en caoutchouc ou
plastique dont l'inconvénient majeur est l'absence de liaison
entre la coupelle tôle et l'intercalaire engendrant les
difficultés de montage et une imprécision dans le
positionnement du ressort.In an attempt to remedy these drawbacks, various solutions have been proposed, namely a) the first solution consists in interposing between the spring and
the sheet metal cup stamped with a rubber interlayer or
plastic whose major drawback is the lack of bonding
between the sheet metal cup and the interlayer generating the
mounting difficulties and imprecision in the
spring positioning.

b) la deuxième solution consiste à réaliser des coupelles d'appui
totalement en caoutchouc ou en plastique dont l'inconvénient
majeur est le coût tres élevé; et c) une troisième solution consiste à équiper les spires
d'extrémité des ressorts de fourreaux en matière plastique qui
ont l'inconvénient d'engendrer des ruptures dues à un phénomène
de corrosion sous fourreau.b) the second solution consists in making support cups
totally rubber or plastic, the disadvantage of which
major is the very high cost; and c) a third solution consists in equipping the turns
end of the plastic sheath springs which
have the disadvantage of causing ruptures due to a phenomenon
corrosion under sheath.

La présente invention a donc pour but de résoudre le nouveau problème technique consistant en la fourniture d'une coupelle d'appui supprimant les bruyances engendrées par frottement, d'un montage aisé permettant de positionrer précisément le ressort , évitant les phénomènes de corrosion tout en étant d'un faible coût . Cette solution doit également éviter tout contact direct entre le ressort et sa coupelle d'appui. The present invention therefore aims to solve the new technical problem consisting in the provision of a support cup eliminating the noises generated by friction, of an easy mounting allowing precise positioning of the spring, avoiding corrosion phenomena while being of low cost. This solution must also avoid any direct contact between the spring and its support cup.

Cette solution doit encore simplifier au maximum la coupelle et réduire au maximum le coût d'outillage de fabrication afin d'envisager une uniformisation des coupelles en tôle emboutie. This solution must further simplify the cup as much as possible and reduce the cost of manufacturing tooling as much as possible in order to envisage standardization of the stamped sheet cups.

La présente invention permet de résoudre pour la première fois les problèmes techniques énoncés ci-dessus , d'une manière particulièrement simple , utilisable à l'échelle industrielle. The present invention makes it possible to solve for the first time the technical problems stated above, in a particularly simple manner, usable on an industrial scale.

Ainsi, selon un premier aspect, la présente invention fournit une coupelle d'appui pour ressort hélicoïdal de suspension de véhicule , comprenant un élément intercalaire non métallique interposé entre la coupelle et l'extrémité du ressort, caractérisée en ce que ledit élément intercalaire comprend des moyens de solidarisation avec ladite coupelle. Thus, according to a first aspect, the present invention provides a support cup for a coil spring for vehicle suspension, comprising a non-metallic intermediate element interposed between the cup and the end of the spring, characterized in that said intermediate element comprises means for securing with said cup.

Selon un mode de réalisation avantageux, les moyens de solidarisation de l'élément intercalaire avec la coupelle forment corps avec l'élément intercalaire qui est ainsi monobloc,
Selon un autre mode de réalisation avantageux de l'invention, les moyens de solidarisation précités comprennent un téton de solidarisation et de centrage.According to an advantageous embodiment, the means for securing the intermediate element with the cup form a body with the intermediate element which is thus in one piece,
According to another advantageous embodiment of the invention, the above-mentioned securing means comprise a securing and centering pin.

Selon un autre mode de réalisation avantageux de l'invention, le téton précité est de forme externe doublement tronconique de manière à définir un point de passage à force. According to another advantageous embodiment of the invention, the aforementioned stud is of doubly frustoconical external shape so as to define a point of force passage.

Selon une variante de réalisation particulière, l'angle des cônes définissant la forme extérieure du téton est compris entre 10 et 150 par rapport à la verticale. According to a particular variant embodiment, the angle of the cones defining the external shape of the stud is between 10 and 150 relative to the vertical.

Selon un autre mode de réalisation particulier, le téton précité est réalisé en un matériau élastiquement déformable. De préférence ce matériau élastiquement déformable est choisi entre une matière plastique et un caoutchouc. Le matériau élastiquement déformable du téton peut être identique ou différent du matériau constituant l'élément intercalaire. According to another particular embodiment, the aforementioned stud is made of an elastically deformable material. Preferably, this elastically deformable material is chosen between a plastic material and a rubber. The elastically deformable material of the stud may be identical to or different from the material constituting the intermediate element.

Selon un deuxième aspect, l'invention fournit également une suspension de véhicule caractérisée en ce qu'elle est équipée d'une coupelle d'appui comportant un élément intermédiaire, telle que précédemment définie. According to a second aspect, the invention also provides a vehicle suspension characterized in that it is equipped with a support cup comprising an intermediate element, as defined above.

On comprend ainsi que l'invention permet de résoudre les problèmes techniques précédemment énoncés et aboutit aux avantages techniques déterminants,inattendus pour l'homme de l'art, précédemment énoncés. It is thus understood that the invention makes it possible to solve the technical problems previously stated and results in the determining technical advantages, unexpected for the person skilled in the art, previously stated.

D'autres buts , caractéristiques et avantages de l'invention apparaitront clairement à l'homme de l'art à partir de la description suivante d'un mode de réalisation particulièrement préféré d'une coupelle d'appui selon l'invention, faite en référence aux dessins annexés , donné simplement à titre d'illustration et qui ne saurait donc en aucune façon limiter la portée de l'invention. Other objects, characteristics and advantages of the invention will become apparent to those skilled in the art from the following description of a particularly preferred embodiment of a support cup according to the invention, made in reference to the accompanying drawings, given simply by way of illustration and which therefore cannot in any way limit the scope of the invention.

Dans les dessins - la figure 1 est une vue en coupe transversale , partielle,
représentant la coupelle d'appui équipée d'un élément
intercalaire selon l'invention et représentant les deux
premières spires du ressort hélicoidal de suspension de véhicule.In the drawings - Figure 1 is a partial cross-sectional view,
representing the support cup fitted with an element
interlayer according to the invention and representing the two
first turns of the vehicle suspension coil spring.

et - la figure 2 est une vue en coupe selon la ligne de trace II-II
de la figure 1 de l'élément intercalaire, la coupelle étant
représentée en traits mixtes, et sans la spire d'extrémité du
ressort
En référence aux figures 1 et 2, une coupelle d'appui 2 en tole emboutie pour ressort hélicoïdal R de suspension de véhicule comprend un élément intercalaire 1 non métallique interposé entre la coupelle 2 et la spire d'extrémité 3 du ressort R.and - Figure 2 is a sectional view along the line of trace II-II
of FIG. 1 of the intermediate element, the cup being
shown in dashed lines, and without the end turn of the
spring
With reference to FIGS. 1 and 2, a support cup 2 in stamped sheet metal for helical spring R for vehicle suspension comprises an intermediate non-metallic element 1 interposed between the cup 2 and the end turn 3 of the spring R.

Selon l'invention, cette coupelle est caractérisée en ce que l'élément intercalaire 1 comprend des moyens 4 de solidarisation de l'élément intercalaire 1 avec la coupelle 2. According to the invention, this cup is characterized in that the intermediate element 1 comprises means 4 for securing the intermediate element 1 with the cup 2.

Selon le mode de réalisation représenté, ces moyens de solidarisation 4 forment corps avec l'élément intercalaire 1 qu; est ainsi monobloc comme clairement visible à la figure 2.  According to the embodiment shown, these securing means 4 form a body with the intermediate element 1 qu; is thus in one piece as clearly visible in Figure 2.

Selon un mode de réalisation préféré, ces moyens de solidarisation 4 comprennent au moins deux tétons 5,6 de solidarisation et de centrage, le téton étant clairement visible à la figure 2. According to a preferred embodiment, these securing means 4 comprise at least two studs 5,6 for securing and centering, the stud being clearly visible in FIG. 2.

Selon une variante de réalisation particulièrement avantageuse, ces tétons 5,6 présentent une forme extérieure doublement tronconique clairement visible à la figure 2.Ce mode de réalisation tel que représenté à la figure 2 fait partie intégrante de l'invention et est donc incorporé intégralement dans la description par référence à la figure 2. According to a particularly advantageous alternative embodiment, these nipples 5, 6 have a doubly frustoconical external shape clearly visible in FIG. 2. This embodiment as shown in FIG. 2 is an integral part of the invention and is therefore fully incorporated in the description with reference to FIG. 2.

Selon une caractéristique particulièrement avantageuse, l'angle alpha définissant la forme extérieure des cônes du téton est compris entre 10 et 150 comme clairement indiqué à la figure 2. According to a particularly advantageous characteristic, the angle alpha defining the external shape of the cones of the nipple is between 10 and 150 as clearly indicated in FIG. 2.

Autrement dit, ces tétons 5 et 6 sont de forme biconique ou en double tronc de cône. Ils sont de préférence percés d'un orifice coaxial 10 traversant allant en s'évasant dans la direction opposée au corps de l'élément intercalaire 1, c'est-à-dire que cet orifice 10 présente une partie 10a cônique dont la grande base se trouve à la partie libre 8 du téton tel que 6. In other words, these pins 5 and 6 are biconical in shape or in double truncated cone. They are preferably pierced with a coaxial orifice 10 passing through, flaring in the direction opposite to the body of the intermediate element 1, that is to say that this orifice 10 has a conical part 10a whose large base is found in the free part 8 of the nipple such as 6.

Les tétons 5, 6, biconiques, présentent donc un point proéminent 12 à la jonction des deux parties côniques inversées 8,9 , visibles figure 2. Ainsi, les tétons 5,6 présentent un diamètre extérieur d de la grande base défini par le point 12 qui constitue une ligne de jonction entre les cônes 8,9 , supérieur au diamètre D de l'orifice 14 de la coupelle dans lequel il vient se loger.Le diamètre dl de la petite base du tronc de cône 8 est quant à lui inférieur au diamètre O de l'orificeî4 de la coupelle. The nipples 5, 6, biconical, therefore have a prominent point 12 at the junction of the two inverted conical parts 8.9, visible in FIG. 2. Thus, the nipples 5.6 have an outside diameter d of the large base defined by the point 12 which constitutes a junction line between the cones 8, 9, greater than the diameter D of the orifice 14 of the cup in which it is housed. The diameter dl of the small base of the truncated cone 8 is for its part to the diameter O of the orificeî4 of the cup.

ce qui permet l'introduction aisée des tétons 5,6 dans les orifices 14 de la coupelle 2. On comprend ainsi que l'on obtient les avantages techniques déterminants précédemment énoncés. which allows the easy introduction of the pins 5.6 into the holes 14 of the cup 2. It is thus understood that one obtains the determining technical advantages previously stated.

Nat nvention comprend tous les moyens constituant les équivalents techniques des moyens décrits ainsi que leurs diverses combinaisons.  Nat nvention includes all the means constituting the technical equivalents of the means described as well as their various combinations.
