Description
Ressors hélicoïdal de suspension non bruyant. Non-noisy helical suspension springs.
La présente invention concerne un ressort hélicoidal de suspension non bruyant
La demande de brevet français 87-18200 décrit un ressort hélicoïdal de compression composé de plusieurs spires de fil métallique enroulées en hélice et possédant au moins un gousset attaché audit fil. caractérisé en ce que ledit gousset comporte au moins une languette présentant une surface hélicoidale coaxiale audit ressort et tangente audit fil selon un arc d'hélice.The present invention relates to a non-noisy helical suspension spring
French patent application 87-18200 describes a helical compression spring composed of several turns of metal wire wound in a helix and having at least one gusset attached to said wire. characterized in that said gusset comprises at least one tongue having a helical surface coaxial with said spring and tangent to said wire according to a helical arc.
Les languettes hélicsidaies tangentes au fil s'interposent entre les spires dudit ressort pour leur éviter de s entreonoquer. The helical tabs tangent to the wire are interposed between the turns of said spring to prevent them from being interlocked.
Cependant. la flexibilité de ce type de gousset n'est pas satisfaisante surtout dans les cas où le gousset doit être de longvezr importante. Ces goussets posent également des problèmes ce montage toujours cans le cas où l'on veut recouvrir une grande longueur de spires ou dans le cas où la courbure du ressort est importante. However. the flexibility of this type of gusset is not satisfactory, especially in cases where the gusset must be long. These gussets also pose problems, this mounting always in the case where it is desired to cover a large length of turns or in the case where the curvature of the spring is large.
Ce problème est résolu pour la première fois de manière satisalsante par le dispositif de la présente invention. This problem is satisfactorily resolved for the first time by the device of the present invention.
La présente invention propose donc un ressort hélicoidal de suspension non bruyant composé de plusieurs spires de -fil métallique enroulées en hélice et possédant au moins un gousset attacné audit fil, caractérisé en ce que les goussets sont constitués d'anneaux ouverts,en forme de C,espacés et reliés entre eux par un cordon, chaque anneau comportant deux languettes planes parallèles à une distance égale au diamètre du fil du ressort. The present invention therefore provides a non-noisy helical suspension spring composed of several turns of metal wire wound in a helix and having at least one gusset attached to said wire, characterized in that the gussets consist of open rings, in the form of a C , spaced apart and connected together by a cord, each ring comprising two flat tongues parallel to a distance equal to the diameter of the spring wire.
Selon une autre caractéristique de l'invention, l'écartement et la largeur des anneaux sont adaptés à la courbure des spires du ressort. According to another characteristic of the invention, the spacing and the width of the rings are adapted to the curvature of the turns of the spring.
Selon ennore une autre caractéristique de l'invention, les anneaux comportent un moyen de renfort suivant le profil en C, ledit moyen de renfort comprenant au moins une nervure qui s zend à l'extérieur sur la partie dorsale de chaque anneau. According to another characteristic of the invention, the rings comprise a reinforcement means according to the C-shaped profile, said reinforcement means comprising at least one rib which extends outside on the dorsal part of each ring.
Selon un mode de réalisation particulier de l'invention,
le ocroon est constitué par une bande transversale reliant lesdits
anneaux au niveau de leur partie dorsale.According to a particular embodiment of the invention,
the ocroon is constituted by a transverse band connecting the said
rings at the level of their dorsal part.
Selon une autre caractéristique de l'invention, lesdites
languettes sont pourvues å leur extrémité d'ergots prismatiques triangulaires, l'une des faces du prisme étant tangente audit fil.According to another characteristic of the invention, said
tongues are provided at their end with triangular prismatic lugs, one of the faces of the prism being tangent to said wire.
Les goussets antibruit de l'invention sont positionnés
sur le fil du ressort dans des zones déterminées lors d'essais dynamiques. Cette mise en place permet d'éviter la bruyance engendrée par le contact des spires à ressort au cours du fonctionnement ce la suspension.The ear muffs of the invention are positioned
on the spring wire in areas determined during dynamic tests. This installation makes it possible to avoid the noise generated by the contact of the spring coils during operation of the suspension.
Le gousset de l'invention peut être réaiisé de manière linéaire et, gracie à la flexibilité au cordon de liaison et à l'es=--e prévu entre chaque anneau, s'adapter à différentes courbures ae ressorts. The gusset of the invention can be made linearly and, thanks to the flexibility of the connecting cord and the es = - e provided between each ring, adapt to different curvatures with springs.
0n évite de cette façon la réalisation d'un moule spécifique à chaque type de ressort à équiper. This avoids the creation of a specific mold for each type of spring to be fitted.
La matière constituant le clip peut être de la résine polyamide cu pclyacétale. The material constituting the clip may be polyamide or polyacetal resin.
La présente invention sera mieux comprise à la lecture de la cescription qui va suivre accompagnée des dessins annexés sur lesquels:
La figure 1 est une vue en perspective d'un ressort hélicoïdal selon l'invention avec un gousset constitué d'anneaux.The present invention will be better understood on reading the description which follows, accompanied by the appended drawings in which:
Figure 1 is a perspective view of a coil spring according to the invention with a gusset made of rings.
La figure 2 est une vue en perspective d'un gousset de l'invention à l'état libre. Figure 2 is a perspective view of a gusset of the invention in the free state.
Le ressort hélicoïdal représenté sur la figure 1 est composé de plusieurs spires de fil métallique enroulées en hélice et sur lesquelles sont montés des goussets antibruit. The helical spring shown in Figure 1 is composed of several turns of metal wire wound in a helix and on which are mounted ear muffs.
Les goussets antibruit 2 sont constitués d'anneaux ouverts 3 en forme de C espacés et reliés entre eux par un cordon 4. The noise canceling gussets 2 consist of open rings 3 in the form of C spaced apart and connected together by a cord 4.
Chaque anneau 3 comporte deux languettes 5, 6 parallèles, à -e distance égale au diamètre du fil du ressort 1. A l'extrémité de chaque anneau 3 en forme de C, sont prévus des. Each ring 3 has two tongues 5, 6 parallel, at a distance equal to the diameter of the spring wire 1. At the end of each C-shaped ring 3, are provided.
ergots 7 dont la forme permet l'encliquetage aisé des anneaux 3 sur le fil du ressort 1 et qui une fois montés interdisent leur désolidarisation.pins 7, the shape of which allows easy snap-fastening of the rings 3 on the wire of the spring 1 and which, once mounted, prohibit their separation.
Après montage , la courbure prise par le gousset sur le ressort 1 assure la liaison selon l'axe de l'hélice du ressort. Les ergots 7 sont réalisés sous forme prismatique triangulaire, l'une des faces du prisme étant tangente audit fil du ressort 1. After mounting, the curvature taken by the gusset on the spring 1 provides the connection along the axis of the spring propeller. The lugs 7 are produced in triangular prismatic form, one of the faces of the prism being tangent to said wire of the spring 1.
Le montage des goussets sur le ressort comme représenté sur la figure 1 empêche que les spires du ressort en stentrecnoquant ne se détériorent ou fassent du bruit.
L'écartement et la largeur ces anneaux 3 sont adaptés à la courbure des spires du ressort 1.The mounting of the gussets on the spring as shown in Figure 1 prevents the turns of the spring by stentrecnoquant deteriorate or make noise.
The spacing and the width of these rings 3 are adapted to the curvature of the turns of the spring 1.
En effet, lorsque ie gousset est monté sur le ressort avec l'ouverture ces anneaux 3 orientée vers l'intérieur de la spire , les anneaux s'adaDtent è la courbure du fil constituant le ressort e se rapprochent les uns des autres au niveau des extrenités ces languettes 5,6. In fact, when the gusset is mounted on the spring with the opening of these rings 3 oriented towards the inside of the turn, the rings adenDent to the curvature of the wire constituting the spring e approach each other at the level of the extrenités these tabs 5.6.
Pour un écartement et une largeur d'anneaux déterminés, il existe dnnc un intervalle et une valeur limite de la courbure au ressert à équiper. For a given spacing and width of rings, there is therefore an interval and a limit value for the curvature of the spring to be fitted.
Les anneaux 3 comportent un moyen de renfort suivant le profil en C. Ce moyen oe renfort permet d'obtenir un meilleur serrage ce chaque anneau du gousset sur le fil du ressort et donc une meilleure tenue de l'ensemble. The rings 3 comprise a reinforcement means according to the C profile. This reinforcement means makes it possible to obtain a better tightening of this each ring of the gusset on the spring wire and therefore better resistance of the assembly.
Le moyen de renfort tel qu'il est représente sur la figure 2 comprend une nervure 9 s'étendant à l'extérieur sur la partie dorsale 8 de l'anneau 3
Dans le cas où la largeur de l'anneau est importante, on peut réaliser le moyen de renfort avec plusieurs nervures 9 ou une seule nervure plus large s'étendant toujours sur la partie dorsale de l'anneau. La nervure suit donc le profil en C de l'anneau et se prolonge jusqu'au niveau des languettes 5, 6.The reinforcing means as shown in Figure 2 comprises a rib 9 extending outside on the dorsal part 8 of the ring 3
In the case where the width of the ring is large, the reinforcing means can be made with several ribs 9 or a single wider rib still extending over the dorsal part of the ring. The rib therefore follows the C profile of the ring and extends to the level of the tongues 5, 6.
Le - cordon de liaison 4 entre les anneaux est constitué par une bande transversale reliant lesdits anneaux au niveau de leur partie dorsale 8 . Ce cordon 4 est réalisé de préférence avec le même matière ce celle des anneaux. The connecting cord 4 between the rings is constituted by a transverse band connecting said rings at their dorsal part 8. This cord 4 is preferably made with the same material as that of the rings.
L'écartement des anneaux et la présence du cordon de liaison permet d'obtenir la longueur de gousset désirée par coupure duait corde entre deux anneaux consécutifs. The spacing of the rings and the presence of the connecting cord makes it possible to obtain the desired gusset length by cutting the milk rope between two consecutive rings.
