Abstract
Description
Roue à suspension centrale intégrée.Integrated central suspension wheel.
La présente invention se rapporte à une roue à suspension centrale intégrée, utilisable pour le transport des charges en général, chaque fois que la fonction roulage existe.The present invention relates to a wheel with integrated central suspension, usable for transporting loads in general, whenever the rolling function exists.
On connait déjà des systèmes dans lesquels les deux fonctions de roulage et de suspension sont intégrées dans la même pièce et selon lesquelles le centre de la roue est mobile par rapport à son profil extérieur, qui est indéformable.Systems are already known in which the two driving and suspension functions are integrated in the same part and according to which the center of the wheel is movable relative to its external profile, which is undeformable.
Ceux-ci présentent des avantages par rapport à d'autres systemes selon lesquels la partie centrale de la roue est fixe, mais dont la périphérie est déformable au contact du sol, pour les besoins dela fonction suspension.These have advantages compared to other systems according to which the central part of the wheel is fixed, but whose periphery is deformable in contact with the ground, for the needs of the suspension function.
Cette caractéristique est en effet en contradiction avec les condit ions d'un bon roulage; pour lequel la partie extérieure du système doit rester circulaire, donc indéformable, et le contact avec le sol ponctuel.This characteristic is in fact in contradiction with the conditions for good driving; for which the external part of the system must remain circular, therefore undeformable, and the contact with the ground punctual.
Cependant, les systèmes antérieurs, dont le centre de la roue est mobile par rapport à la'périphérie, sont en général complexes et constitués de moyens métalliques comportant de multiples pièces, telles que ressorts, biellettes, articulations, etc., dont le montage est long, donc onéreux, fragile, bruyant, soumis à la corrosion et dont la permanence des caractéristiques laisse à désirer.However, prior systems, the center of the wheel of which is movable relative to the periphery, are generally complex and made up of metallic means comprising multiple parts, such as springs, links, articulations, etc., the mounting of which is long, therefore expensive, fragile, noisy, subject to corrosion and whose permanence of characteristics leaves something to be desired.
L'objet de la présente invention a pour but de palier les inconvénients ci-dessus et sera décrit à titre d'exemple non limitatif au regard des figures 1 à 7 ci-jointes, qui montrent respectivement - figure 1 : une vue en perspective d'une roue selon l'invention, - figure 2 : une vue analogue éclatée, - figure 3 : une coupe transversale de la bande de roulement, - figure 4 : une vue en élévation d'un détail, - figures 5 a et b : un schéma de fonctionnement de la roue en
charge, - figures 6 a et b : un schéma de fonctionnement de la roue lors
qu'elle rencontre un obstacle, - figure 7 : une variante indiquant une possibilité de décoration
de la roue.The object of the present invention aims to overcome the above drawbacks and will be described by way of non-limiting example with regard to Figures 1 to 7 attached, which respectively show - Figure 1: a perspective view of 'a wheel according to the invention, - Figure 2: a similar exploded view, - Figure 3: a cross section of the tread, - Figure 4: an elevational view of a detail, - Figures 5 a and b: a wheel operating diagram in
load, - Figures 6 a and b: a diagram of the wheel's operation when
that it encounters an obstacle, - figure 7: a variant indicating a possibility of decoration
of the wheel.
Les principales parties constitutives de la roue selon la figure 1 sont plus clairement visibles à la figure 2 qui montre une vue éclatée de l'objet de l'invention.The main constituent parts of the wheel according to Figure 1 are more clearly visible in Figure 2 which shows an exploded view of the object of the invention.
La bande de roulement 2 est constituée par tout revêtement à haut coefficient de frottement possédant une bonne tenue à l'abrasion.The tread 2 is formed by any coating with a high coefficient of friction having good abrasion resistance.
La surface peut comporter des reliefs 3 améliorant encore le coefficient de frottement.The surface may include reliefs 3 further improving the coefficient of friction.
Cette bande 2, qui assure le contact avec le sol, doit être de forme circulaire, rigide et pratiquement indéformable.This strip 2, which ensures contact with the ground, must be circular, rigid and practically undeformable.
Pour ce faire, on peut adjoindre dans son épaisseur une bague 4 en un matériau dur tel que de l'acier ou une matière plastique adéquate, fixée par tout moyen connd, du type collage, ou par adhérence, ou encore par création d'obstacles s'opposant à sa sortie.To do this, it is possible to add in its thickness a ring 4 made of a hard material such as steel or an adequate plastic material, fixed by any connd means, of the bonding type, or by adhesion, or even by creating obstacles. opposing its exit.
Le dimensionnement de la bande de roulement varie notamment avec la charge à véhiculer et létat de surface de roulage.The size of the tread varies in particular with the load to be transported and the running surface condition.
La roue 1 est solidarisée au véhicule porteur de la charge grâce à un moyeu 5, à l'intérieur duquel on introduit à force un axe tubulaire non représenté. The wheel 1 is secured to the load-carrying vehicle by means of a hub 5, inside of which a tubular axis, not shown, is forced.
Ce moyeu 5 est relié à la bande de roulement 2 par l'intermédiaire de jambes de force 6 déformables, de façon élastique, dont le nombre et la forme sont adaptés à la charge transportée ainsi qucà la loi de déformation souhaitée pour ledit moyeu 5.This hub 5 is connected to the tread 2 by means of resiliently deformable struts 6, the number and shape of which are adapted to the load transported as well as to the desired deformation law for said hub 5.
La géométrie des jambes de force 6 est conçue de manière à ce que la droite d'effort 7 passant par le centre de la roue coupe à tout moment, lors de la rotation de cette dernière, les lignes extérieures 8 définissant la géométrie de l'élément. Cette règle assure une déformation progressive du système selon l'inventionO La forme de réalisation illustrée par les figures ci-dessus comporte ainsi des jambes de force 6 constituant un angle A, et se trouve préférentiellement obtenue à partir d'un élastomère moulé sous pression, dont les caractéristiques de raideur sont définies expérimentalement selon les conditions de son emploi futur.The geometry of the struts 6 is designed so that the force line 7 passing through the center of the wheel cuts at any time, during the rotation of the latter, the outer lines 8 defining the geometry of the element. This rule ensures a progressive deformation of the system according to the invention. The embodiment illustrated by the above figures thus comprises struts 6 constituting an angle A, and is preferably obtained from a die-cast elastomer, whose stiffness characteristics are defined experimentally according to the conditions of its future use.
Le fonctionnement du dispositif selon l'invention est illustré par les schémas 5a et b et 6a et b En terrain plat, sans obstacle, le dispositif non chargé de la figure 5a se transforme selon la figure 5b, lorsque l'on y dispose une charge 9. Le centre O de la roue au repos s'excentre alors en 0' représentant une flèche 7. Lors du roulage, chaque jambe de force 6 passe de sa longueur h au repos, respectivement à h - f lorsqu'elle se trouve située entre le centre de la roue et son point de contact avec le sol et à h + f lorsqu'elle se tend dans la position diamétralement opposée. Il y a donc rotation de la roue, possédant ainsi un rayon variable, ce qui assure correctement et indépendamment l'une de ltautre les deux fonctions roulage et suspension, ceci dans un encombrement minimum.The operation of the device according to the invention is illustrated by diagrams 5a and b and 6a and b In flat terrain, without obstacle, the device not loaded in Figure 5a is transformed according to Figure 5b, when there is a load 9. The center O of the wheel at rest is then offset at 0 'representing an arrow 7. During rolling, each strut 6 passes from its length h at rest, respectively to h - f when it is located between the center of the wheel and its point of contact with the ground and at h + f when it tightens in the diametrically opposite position. There is therefore rotation of the wheel, thus having a variable radius, which correctly and independently ensures one of the other the two rolling and suspension functions, this in a minimum bulk.
Lorsqu'un obstacle 10 doit être franchi (figure 6b), on considère que le filtrage du système est correct lorsque le centre de la roue constituant le point de liaison avec la charge ne bouge pas verticalement. Ce sont donc les jambes 6 qui se déforment en conséquence. Dans ce cas, la bande de roulement 2 se déplace verticalement d'une valeur h'. When an obstacle 10 must be crossed (FIG. 6b), it is considered that the filtering of the system is correct when the center of the wheel constituting the point of connection with the load does not move vertically. It is therefore the legs 6 which deform accordingly. In this case, the tread 2 moves vertically by a value h '.
La jambe 6 se trouvant entre l'axe et le haut de l'obstacle se comprime tandis que celle qui lui est opposée se tend. L'obstacle franchi, les jambes 6 retrouvent leur position initiale.The leg 6 located between the axis and the top of the obstacle compresses while that opposite it stretches. The obstacle crossed, the legs 6 return to their initial position.
Les résultats expérimentaux montrent que le fonctionnement de la roue ci-dessus est optimal lorsque les deux conditions suivantes sont remplies - le rayon de la roue doit être de l'ordre de six à huit fois la
déformation maximale de la jambe, - la flèche due à la charge statique maximale supportée est voisine
du tiers de la déformation maximale de la jambe.Experimental results show that the operation of the above wheel is optimal when the following two conditions are met - the radius of the wheel should be in the range of six to eight times the
maximum deformation of the leg, - the deflection due to the maximum static load supported is close
one-third of the maximum leg deformation.
L'objet de l'invention étant principalement destinée au transport de jeunes enfants, notamment par poussettes, l'esthétique de la roue a un rôle important à jouer. C'est pourquoi il peut être souhaitable de donner aux jambes de force 6 un aspect amusant, comme représenté par exemple à la figure 7, tel qu'une ressemblance avec des jambes humaines munies de chaussures il, se pliant et se dépliant successivement, lors du fonctionnement du dispositif. On pourrait de la même façon utiliser ce phénomène en combinaison avec la représentation de parties analogues d'animaux, ou de tout objet susceptible d'attirer l'attention des enfants. The object of the invention being mainly intended for the transport of young children, in particular by strollers, the aesthetics of the wheel has an important role to play. This is why it may be desirable to give the struts 6 an amusing appearance, as shown for example in FIG. 7, such as a resemblance to human legs provided with shoes, folding and unfolding successively, during the operation of the device. We could similarly use this phenomenon in combination with the representation of analogous parts of animals, or of any object likely to attract the attention of children.
