Description

"Enveloppe anti-glissement pour roue de véhicule" "Anti-slip casing for vehicle wheel"
La présente invention concerne une enveloppe anti-glissement pour roue de véhicule du type comportant une portion de couverture de la bande de roulement de la roue apte à augmenter l'adhérence au sol.The present invention relates to an anti-slip casing for a vehicle wheel of the type comprising a tread portion of the tread of the wheel capable of increasing the adhesion to the ground.
L'invention trouvera son application particulière dans le domaine des accessoires de véhicules pour automobiles pour constituer des dispositifs anti- dérapant. Ces dispositifs sont notamment utilisables en cas de perturbations météorologiques susceptibles de recouvrir le sol de neige ou de glace.The invention will find its particular application in the field of automotive vehicle accessories to constitute anti-slip devices. These devices are particularly useful in case of weather disturbances likely to cover the ground with snow or ice.
Recouvrir le pneumatique d'une roue de véhicule par une enveloppe de sorte à améliorer son adhérence est une technologie assez ancienne tel que le démontre le document US 2 682 907 divulguant une enveloppe applicable sur la bande de roulement de la roue et présentant des propriétés de frottement adaptées ainsi que deux portions latérales applicables sur les flancs de la roue.Covering the tire of a vehicle wheel with an envelope so as to improve its adhesion is a fairly old technology as demonstrated by document US 2,682,907 disclosing an envelope applicable to the tread of the wheel and having tire properties. friction fit and two side portions applicable to the sidewalls of the wheel.
Plus récemment, on a proposé dans EP-A- 1 165 329 un dispositif similaire dans sa structure générale. Cette publication européenne affirme More recently, it has been proposed in EP-A-1 165 329 a similar device in its general structure. This European publication affirms
qu'une marge dimensionnelle de plus de 4% entre la circonférence de la bande de roulement de la roue et la paroi interne du dispositif permet le montage autonome autour du pneumatique lors de la rotation de la roue.that a dimensional margin of more than 4% between the circumference of the tread of the wheel and the inner wall of the device allows the autonomous mounting around the tire during the rotation of the wheel.
Moins encombrants et moins lourds que les chaînes neige traditionnelles, ces dispositifs antérieurs sont cependant aussi moins efficaces sur le plan de l'adhérence au sol.Less bulky and lighter than traditional snow chains, these prior devices are however also less effective in terms of grip on the ground.
Il existe actuellement un besoin de proposer une technologie du type enveloppe anti-glissement présentant des capacités de transmission de puissance entre la roue et le sol améliorées. L'invention s'inscrit dans ce cadre et propose à cet effet une nouvelle enveloppe comportant au moins une bande souple appliquée sur la paroi extérieure de la portion de couverture de la bande de roulement de la roue, la ou les bandes souples étant configurées pour produire un effet crampon sur le sol. On entend par là que chaque bande souple forme un élément d'accroché additionnel sur le sol constituant un relief autour de la bande de roulement, ce qui permet d'augmenter la surface de contact entre l'enveloppe et le sol et augmenter la capacité d'accroché en particulier sur la neige ou sur la glace.There is currently a need to provide slip-resistant type technology with improved wheel-to-ground power transmission capabilities. The invention falls within this framework and proposes for this purpose a new envelope comprising at least one flexible strip applied to the outer wall of the tread portion of the tread of the wheel, the flexible strip or strips being configured to produce a crampon effect on the floor. By this is meant that each flexible band forms an additional hooking element on the ground constituting a relief around the tread, which makes it possible to increase the contact surface between the envelope and the ground and to increase the capacity of the hung especially on snow or ice.
On a également constaté que l'enveloppe anti-glissement équipée de bandes souples était à même d'augmenter la durée de vie de l'enveloppe en la solidifiant. En particulier, la portion de couverture fortement sollicitée lors du roulage du véhicule est mieux protégée.It has also been found that the anti-slip envelope equipped with flexible strips was able to increase the life of the envelope by solidifying it. In particular, the portion of coverage heavily stressed during the rolling of the vehicle is better protected.
On forme ainsi un ensemble d'une plus grande longévité améliorant les capacités de transmission de puissance entre la roue et le sol tant en phase d'accélération que de freinage du véhicule. D'autres buts et avantages apparaîtront au cours de la description qui suit qui présente un mode de réalisation préféré de l'invention cependant non limitatif.Thus, a longer-lasting assembly improves the power transmission capabilities between the wheel and the ground both in acceleration and braking phase of the vehicle. Other objects and advantages will become apparent from the description which follows, which presents a preferred embodiment of the invention, which is however non-limiting.
Auparavant, il est rappelé que l'invention concerne une enveloppe antiglissement pour roue de véhicule comportant une portion de couverture de la bande de roulement de la roue apte à augmenter l'adhérence au sol. Cette enveloppe comprend au moins une bande souple appliquée sur la paroi extérieure de la portion de couverture et configurée pour produire un effet crampon sur le sol. Suivant des variantes préférées mais non limitatives, cette enveloppe est telle que :Previously, it is recalled that the invention relates to an anti-slip envelope for a vehicle wheel comprising a tread portion of the tread of the wheel capable of increasing the adhesion to the ground. This envelope comprises at least one flexible strip applied on the outer wall of the cover portion and configured to produce a crampon effect on the ground. According to preferred but non-limiting variants, this envelope is such that:
- la bande souple est solidaire de la portion de couverture par au moins une zone de solidarisation orientée sensiblement suivant la largeur de la portion de couverture,the flexible strip is secured to the covering portion by at least one fastening zone oriented substantially along the width of the covering portion,
- la bande souple est solidaire de la paroi extérieure de la portion de couverture par deux zones de solidarisation situées à proximité de deux bords opposés de la bande souple,the flexible strip is secured to the outer wall of the covering portion by two securing zones located near two opposite edges of the flexible strip,
- les deux autres bords de la bande souple sont libres, - la distance séparant les deux zones de solidarisation est inférieure à la dimension de la bande souple entre les deux zones de solidarisation,the other two edges of the flexible strip are free, the distance separating the two fastening zones is smaller than the dimension of the flexible strip between the two fastening zones,
- la dimension de la bande souple entre les deux zones de solidarisation est supérieure d'au moins 10% à la distance séparant les deux zones de solidarisation, - la dimension de la bande souple entre les deux zones de solidarisation est supérieure à 20 mm,the dimension of the flexible strip between the two fastening zones is at least 10% greater than the distance separating the two fastening zones; the dimension of the flexible strip between the two fastening zones is greater than 20 mm,
- la dimension de la bande souple entre les deux zones de solidarisation est de l'ordre de 70 mm,the dimension of the flexible band between the two zones of attachment is of the order of 70 mm,
- la solidarisation de la bande souple et de la portion de couverture est faite par des coutures,- The fastening of the flexible band and the cover portion is made by seams,
- la solidarisation de la bande souple et de la portion de couverture est faite par un système du type Velcro ®,the fastening of the flexible band and the covering portion is made by a Velcro® type system,
- la bande souple est en tissu,- the flexible band is fabric,
- elle comporte une bande de protection recouvrant la zone de solidarisation,it comprises a protective strip covering the fastening zone,
- la bande de protection est solidaire, d'une part, de la portion de couverture et, d'autre part, de la bande souple,the protective strip is secured, on the one hand, to the covering portion and, on the other hand, to the flexible strip,

- la portion de couverture est en tissu, - elle comporte sept bandes souples réparties régulièrement suivant la circonférence de la portion de couverture,- the covering portion is made of fabric, - it comprises seven flexible strips regularly distributed along the circumference of the covering portion,
- elle comporte, de part et d'autre de la portion de couverture :- it includes, on both sides of the portion of coverage:
- une portion interne applicable sur le flanc intérieur de la roue, - une portion externe applicable sur le flanc extérieur de la roue. Les dessins ci-joints sont donnés à titre d'exemples et ne sont pas limitatifs de l'invention. Ils représentent seulement un mode de réalisation de l'invention et permettront de la comprendre aisément. La figure 1 présente une vue de côté d'une roue équipée d'une enveloppe selon l'invention.an internal portion applicable on the inner side of the wheel, an external portion applicable on the outer side of the wheel. The accompanying drawings are given by way of example and are not limiting of the invention. They represent only one embodiment of the invention and will make it easy to understand. Figure 1 shows a side view of a wheel equipped with an envelope according to the invention.
Les figures 2 à 4 montrent successivement les phases d'assemblage d'une bande souple à une enveloppe.Figures 2 to 4 show successively the phases of assembly of a flexible band to an envelope.
Les figures 5 et 6 montrent une variante de l'invention avec des bandes de protection.Figures 5 and 6 show a variant of the invention with protection strips.
L'enveloppe 1 telle qu'illustrée en figure 1 comporte une portion de couverture 2 recouvrant la bande de roulement du pneumatique 7 de la roue.The casing 1 as illustrated in FIG. 1 comprises a cover portion 2 covering the tread of the tire 7 of the wheel.
Différents matériaux sont utilisables pour constituer la portion de couverture 2 telle une matière textile à base de fibres polymères et notamment des fibres polyamides.Different materials can be used to form the covering portion 2 such a textile material based on polymeric fibers and in particular polyamide fibers.
Pour assurer le maintien en position de la portion de couverture 2 lors du fonctionnement, des moyens de rétention sont formés. Classiquement, l'enveloppe 1 présente à cet effet des flancs bordant la portion de couverture 2 de sorte à s'appliquer sur la paroi latérale interne et la paroi latérale externe de la roue.To maintain the position of the cover portion 2 during operation, retention means are formed. Classically, the casing 1 has for this purpose flanks bordering the cover portion 2 so as to be applied to the inner side wall and the outer side wall of the wheel.
La figure 1 illustre la formation d'un flanc 8.Figure 1 illustrates the formation of a flank 8.
Cette disposition n'est cependant pas limitative et d'autres types de moyens de fixation en position de l'enveloppe 1 sur la roue entrent dans le cadre de l'invention. Dans le cas illustré, un anneau élastique 9 borde le flanc 8 de sorte à tendre l'enveloppe 1.This arrangement is however not limiting and other types of fastening means in position of the casing 1 on the wheel are within the scope of the invention. In the case illustrated, an elastic ring 9 borders the sidewall 8 so as to tension the envelope 1.
Selon l'invention, la portion de couverture 2 reçoit une ou plusieurs bandes souples 3 dont un mode de réalisation est présenté aux figures 1 à 6.According to the invention, the cover portion 2 receives one or more flexible strips 3, an embodiment of which is shown in FIGS. 1 to 6.
Ces bandes 3 peuvent être réalisées dans la même matière que la portion de couverture 2 et sont avantageusement réparties sur la circonférence de la portion de couverture 2.These strips 3 can be made of the same material as the covering portion 2 and are advantageously distributed around the circumference of the covering portion 2.
La formation des bandes souples 3 permet de créer des reliefs sur la surface extérieure de la portion de couverture 2 tout en préservant le caractère souple de l'ensemble avantageux lors des phases du montage et aussi lors du stockage.The formation of the flexible strips 3 makes it possible to create reliefs on the outer surface of the cover portion 2 while preserving the character flexible all advantageous during the phases of assembly and also during storage.
Il est préférable que la bande souple 3 ait une liberté de mouvement relativement à la portion de couverture 2 de sorte à former un pan doté d'une certaine mobilité. En solidarisant une bande 3 assez large avec la portion de couverture 2 par une seule ligne de fixation, la bande 3 forme ainsi un pan pivotant relativement au reste de l'enveloppe 1.It is preferable that the flexible band 3 has a freedom of movement relative to the cover portion 2 so as to form a pan with a certain mobility. By joining a relatively broad band 3 with the cover portion 2 by a single fastening line, the band 3 thus forms a swivel panel relative to the remainder of the envelope 1.
Dans le cas illustré, chaque bande 3 est solidarisée sur la portion de couverture 2 au niveau de deux zones de solidarisation 6 situées à proximité des bords transversaux 4 des bandes souples 3. Avantageusement mais non limitativement, les bords transversaux 4 s'étendent suivant l'intégralité de la largeur de la portion de couverture 2.In the case illustrated, each band 3 is secured to the cover portion 2 at two securing zones 6 located near the transverse edges 4 of the flexible strips 3. Advantageously but not limitatively, the transverse edges 4 extend according to the the entire width of the cover portion 2.
Au niveau des zones 6, la fixation des bandes 3 sur la portion de couverture 2 peut être réalisée par des coutures ou par tout autre moyen de fixation tels des systèmes Velcro ® rendant les bandes 3 réglables et amovibles.At the level of the zones 6, the fixing of the strips 3 on the covering portion 2 can be achieved by seams or by any other fastening means such as Velcro ® systems making the strips 3 adjustable and removable.
On a constaté que, en créant un pli sur la bande souple 3 lors de son contact sur le sol, un relief supplémentaire était formé, ce qui améliorait les capacités de traction. En ce sens, suivant un mode préféré de réalisation tel qu'apparaissant aux figures 2 à 4, on fait en sorte que la bande souple 3 est rapportée sur la portion de couverture 2 par deux zones de solidarisation 6 espacées d'une distance B inférieure à la largeur A de la bande souple 3.It has been found that, by creating a fold on the flexible strip 3 upon contact with the ground, additional relief is formed, which improves the pulling capabilities. In this sense, according to a preferred embodiment as shown in Figures 2 to 4, it is arranged that the flexible strip 3 is attached to the cover portion 2 by two securing zones 6 spaced a distance B lower at the width A of the flexible band 3.
On a constaté qu'un écart dimensionnel de l'ordre de 10% donnait les meilleurs résultats. En effet, une telle disposition assure la formation du pli lors du fonctionnement tout en évitant un trop grand déplacement de la bande souple 3 lors du roulage.It was found that a dimensional difference of the order of 10% gave the best results. Indeed, such an arrangement ensures the formation of the fold during operation while avoiding excessive displacement of the flexible band 3 during travel.
Suivant cette configuration, il est avantageux que les deux bords de la bande souple 3 opposés aux bords transversaux 4 restent libres de sorte à ne pas gêner la formation du pli et à former un tunnel. Toujours à titre préféré, la dimension des bandes souples 3 est supérieure à 20 mm et particulièrement de l'ordre de 70 mm pour obtenir les meilleurs effets. Avec de telles dimensions, on peut aisément répartir cette bande souple 3 régulièrement suivant la circonférence de la portion de couverture 2.According to this configuration, it is advantageous that the two edges of the flexible strip 3 opposite the transverse edges 4 remain free so as not to hinder the formation of the fold and to form a tunnel. Also preferably, the size of the flexible strips 3 is greater than 20 mm and particularly of the order of 70 mm to obtain the best effects. With such dimensions, it is easy to distribute this flexible strip 3 regularly along the circumference of the covering portion 2.
Les figures 5 et 6 montrent une variante de réalisation de l'invention avec la formation de bandes de protection 5 aptes à recouvrir la zone de solidarisation 6 pour en protéger la surface (et en particulier les coutures lorsque la solidarisation est opérée par ce moyen) de sorte à améliorer la longévité de l'ensemble et à accroître encore la capacité d'accrochage de l'enveloppe sur le sol.FIGS. 5 and 6 show an alternative embodiment of the invention with the formation of protective strips 5 capable of covering the fastening zone 6 to protect the surface thereof (and in particular the seams when the fastening is effected by this means) so as to improve the longevity of the assembly and further increase the ability of attachment of the envelope on the ground.
Tel qu'illustré, les bandes de protection 5 sont avantageusement configurées pour chevaucher la portion de couverture 2 et la bande souple 3 de sorte à recouvrir la zone de solidarisation 6.As illustrated, the protective strips 5 are advantageously configured to overlap the covering portion 2 and the flexible strip 3 so as to cover the fastening zone 6.
Lorsque le véhicule est en mouvement, la bande souple 3 arrive en contact avec le sol en formant un relief augmentant l'accroche de la roue sur le sol. Dans le cas du mode de réalisation illustré, au moins un pli est formé au surplus de sorte à constituer un relief additionnel fournissant une capacité de traction supplémentaire à l'enveloppe textile 1. Cet effet se renouvelle à chaque bande souple 3 entrant en contact avec le sol.When the vehicle is moving, the flexible band 3 comes into contact with the ground forming a relief increasing the grip of the wheel on the ground. In the case of the illustrated embodiment, at least one fold is formed in addition so as to constitute an additional relief providing additional traction capacity to the textile envelope 1. This effect is renewed to each flexible strip 3 coming into contact with floor.
Le jeu entre la bande souple 3 et la portion de couverture 2 peut être fort élevé de sorte à former des plis importants améliorant l'efficacité. Cela étant, l'usure du système et son confort d'utilisation évoluent dans une direction inverse. Il a été constaté qu'un écart dimensionnel entre les zones de solidarisation et la largeur de la bande souple de l'ordre de 10% donnait le meilleur compromis. En usage, les bandes de protection 5 sont les premières à être sollicitées et elles préservent les bandes souples, améliorant ainsi la longévité de l'ensemble.The clearance between the flexible strip 3 and the cover portion 2 can be very high so as to form large folds improving efficiency. That being so, the wear of the system and its comfort of use evolve in a reverse direction. It was found that a dimensional difference between the zones of attachment and the width of the flexible band of the order of 10% gave the best compromise. In use, the protective strips 5 are the first to be stressed and they preserve the flexible strips, thus improving the longevity of the assembly.
Il a été constaté qu'une enveloppe 1 disposant d'une portion de couverture 2 en matière textile à base de polymère polyamide et dotée de sept bandes souples réparties sur sa périphérie avec une largeur de 70 mm et un écart dimensionnel de 10% relativement aux zones de solidarisation 6 permettait de diminuer d'au moins 15% les distances de freinage et d'augmenter dans les mêmes proportions les capacités d'accélération sans glissement sur le sol enneigé. It has been found that an envelope 1 having a covering portion 2 made of polyamide polymer-based textile material and provided with seven flexible bands distributed around its periphery with a width of 70 mm and a dimensional difference of 10% relative to the zones 6 made it possible to reduce the braking distances by at least 15% and to increase in the same proportions the acceleration capabilities without slipping on the snowy ground.
