Abstract

Rolling member for vehicles having great roadholding on all terrains according to Claim 1 of the main patent 83,03191, which includes a peripheral succession of runners 1 capable of moving radially with respect to the centre by means of extensible elements driven by the hub 4 of the wheel, each extensible element being formed of a radial arm 2 moving in a radial bore 3 counter to a spring 5. Each radial arm is provided with a cage C which carries rollers 10, 15, 24, 25 which are free to rotate and whose axes are perpendicular to the axis of the arm 2 and whose external bearing surface is capable of coming into contact with a longitudinal zone of the internal surface of the bore 3. As the arms 2 and the bores 3 have a quadrilateral-shaped cross-section, the cage C is formed of independent longitudinal bars 13, 18 provided with notches 12, 17 for holding the spindles of the rollers 10, 15. These arrangements prevent the very great wear of the radial arms resulting from friction acting on their entire surface in contact with the bore which guides them.

Description

ORGAJIE DE lOUTwivxT Poul VEHICULIS PRESEIITAIIT UNE GIAIDE ADEBEIICE SUR TOUS TERRAINS
Invention porte sur un organe de roulement pour véhicules présentant une grande adhérence sur tous terrains selon la revendication 1. du brevet principal 8303191, qui comporte une succession périphérique de patins capables de se déplacer radialement par rapport au centre par I'intermédiaire d'éléments extensibles entrainés par le moyeu de la roue, chaque élément extensible étant formé d'un bras radial se déplaçant dans un alésage radial à l'encontre d'un ressort.ORGAJIE DE lOUTwivxT Poul VEHICULIS PRESEIITAIIT A GIAIDE ADEBEIICE ON ALL TERRAIN
The invention relates to a rolling member for vehicles having a high grip on all terrain according to claim 1. of main patent 8303191, which comprises a peripheral succession of pads capable of moving radially relative to the center by means of extensible elements. driven by the wheel hub, each extensible element being formed by a radial arm moving in a radial bore against a spring.

Si un tel organe de roulement donne satisfaction du point de vue de l'adhérence, on constate par contre une très forte usure des bras radiaux du fait du frottement intervenant sur toute leur surface en contact avec l'alésage qui les guide.If such a rolling member is satisfactory from the point of view of adhesion, there is however a very high wear of the radial arms due to the friction occurring over their entire surface in contact with the bore which guides them.

Invention à pour objet de remédier à cet inconvénient et pour ce faire chaque bras radial est pourvu d'une cage qui porte des galets libres en rotation dont les axes sont perpendiculaires à l'axe du bras et dont la surface d'appui externe est apte à venir en contact avec une zone longitudinale de la surface interne de l'alésage. The object of the invention is to remedy this drawback and to do this, each radial arm is provided with a cage which carries free rotating rollers whose axes are perpendicular to the axis of the arm and whose external bearing surface is suitable. to come into contact with a longitudinal zone of the internal surface of the bore.

De tels galets apportent les avantages des roulements à galets sans nécessiter de circuit de retour paralêlle à la surface de contact avec ltélément à guider.Such rollers provide the advantages of roller bearings without the need for a return circuit parallel to the contact surface with the element to be guided.

Selon un mode de réalisation de l'invention applicable lorsque les bras et les alésages ont une section en forme de quadrilatère, la cage est formée de barreaux indépendants longitudinaux pourvus d'encoches de retenue des axes des galets.According to an embodiment of the invention applicable when the arms and the bores have a cross-section in the form of a quadrilateral, the cage is formed of independent longitudinal bars provided with retaining notches for the axes of the rollers.

Avantageusement, deux galets sont prévus pour chaque côté du quadrilatère, les axes des deux galets de deux c & és opposés, pourvus d'un seul barreau, s'introduisant entre et s'appuyant sur les deux extrémités des galets des côtés voisins, pourvus de deux barreaux
Ces dispositions permettent de réaliser une cage complète avec seulement six barreaux indépendants et huit galets simplement calés dans les encoches des barreaux. Le prix de revient est donc extrêmement faible et le montage extrèmement rapide.Advantageously, two rollers are provided for each side of the quadrilateral, the axes of the two rollers of two opposite sides, provided with a single bar, being introduced between and resting on the two ends of the rollers on the neighboring sides, provided of two bars
These arrangements make it possible to produce a complete cage with only six independent bars and eight rollers simply wedged in the notches of the bars. The cost price is therefore extremely low and the assembly extremely fast.

De préférence la cage est interposée entre une butée intérieure solidaire du bras et une butée extérieure solidaire de l'alésage.Preferably the cage is interposed between an inner stop secured to the arm and an outer stop secured to the bore.

La cage constitue ainsi l'organe de liaison entre les deux butées.The cage thus constitutes the connecting member between the two stops.

Selon un autre mode de réalisation de l'invention s'appliquant quelle que soit la forme des sections du bras et de l'alésage, la cage est constituée par l'extrémité tubulaire du bras au delà de sa butée intérieure coopérant avec la butée extérieure solidaire de l'alésage, et les galets sont superposés en croix sur des axes passant par les diagonales de la cage, les galets traversant la cage par des lumières appropriées.According to another embodiment of the invention, whatever the shape of the sections of the arm and of the bore, the cage is formed by the tubular end of the arm beyond its internal stop cooperating with the external stop. integral with the bore, and the rollers are superimposed on a cross on axes passing through the diagonals of the cage, the rollers passing through the cage by suitable lights.

Ce mode de réalisation se révèle lui aussi estremement efficace pour un prix de revient très raisonnable.This embodiment also proves to be very effective for a very reasonable cost price.

Avantageusement, I'alésage étant carré, les galets ont des surfaces de roulement en troncs de corne opposés pour coopérer avec les zones angulaires de l'alésage.Advantageously, the bore being square, the rollers have bearing surfaces in opposite trunks of horn to cooperate with the angular zones of the bore.

La cage constitue ainsi l'organe interdisant toute rotation du bras dans l'alésage.The cage thus constitutes the member preventing any rotation of the arm in the bore.

Les dessins annexés illustrent à titre d'exemple non limitatif ces deux modes de réalisation de l'invention. Dans ces dessins: la figure 1 est une vue en élévation d'un organe de roulement; la figure 2 est une vue en coupe au niveau de l'une des cages interposées entre l'un des bras et son alésage; la figure 3 est une vue cavalière partielle éclatée de cette cage; la figure 4 est une vue en coupe semblable à celle de la figure 2 montrant une autre cage; et la figure 5 est une vue en coupe selon la ligne V-V de la figure 4.The accompanying drawings illustrate by way of nonlimiting example these two embodiments of the invention. In these drawings: FIG. 1 is an elevation view of a rolling member; Figure 2 is a sectional view at one of the cages interposed between one of the arms and its bore; Figure 3 is a partial exploded view of this cage; Figure 4 is a sectional view similar to that of Figure 2 showing another cage; and FIG. 5 is a sectional view along the line V-V of FIG. 4.

On rappelle que l'organe de roulement selon le brevet principal comprend des patins 1 portés par des bras 2 mobiles dans des alésages 3 du moyeu 4 de la roue à l'encontre de ressorts 5 D'autres ressorts 6 réunissent deux à deux les patins qui s'articulent en 7 sur les bras de façon à pouvoir occuper, pour ceux qui sont en contact avec le sol, des positions alignées telles que celles référencees 8 et 9.It will be recalled that the rolling member according to the main patent comprises pads 1 carried by arms 2 movable in bores 3 of the hub 4 of the wheel against springs 5 Other springs 6 join the pads in pairs which are articulated in 7 on the arms so as to be able to occupy, for those who are in contact with the ground, aligned positions such as those referenced 8 and 9.

Pour éviter l'usure des bras 2 contre les parois de l'alésage 3 on a disposé entre chacun d'eux des cages C mieux visibles aux figures 2 et 3 constituées par les barreaux longitudinaux 13, 18.To avoid wear of the arms 2 against the walls of the bore 3, cages C are better visible in each of them, shown in FIGS. 2 and 3 constituted by the longitudinal bars 13, 18.

Les galets 10 situés de face comportent chacun un axe médian 1 1 logé dans l'encoche 12 d'un barreau central 13. Les embouts 14 de ces galets 10 s'appuient contre les extrémités des galets 15 perpendiculaires au plan de la figure. A leur tour ces quatre galets 15 comportent chacun deux axes 16 logés dans des encoches 17 de quatre barreaux 18, de telle manière que la surface d'appui externe des barreaux 10, 15, 24, 25 vienne en contact avec une zone longitudinale de la surface interne de l'alésage 3 en même temps que la surface d'appui interne desdits galets est apte à venir en contact avec une zone longitudinale de la surface externe du bras radial 2.The rollers 10 located from the front each have a central axis 1 1 housed in the notch 12 of a central bar 13. The end pieces 14 of these rollers 10 bear against the ends of the rollers 15 perpendicular to the plane of the figure. In turn, these four rollers 15 each have two axes 16 housed in notches 17 of four bars 18, so that the external bearing surface of the bars 10, 15, 24, 25 comes into contact with a longitudinal zone of the internal surface of the bore 3 at the same time as the internal bearing surface of said rollers is capable of coming into contact with a longitudinal zone of the external surface of the radial arm 2.

Ainsi se trouve réalisé, grâce à quelques pièces simples habilement juxtaposées mais indépendantes les unes des autres, une cage C indéformable qui assure les déplacements sans frottement du bras 2 dans l'alésage 3, et qui sert aussi de liaison entre la butée intérieure
19 solidaire du bras 2, sur laquelle repose le ressort 5, et la butée extérieure 20 solidaire de l'alésage 3.Thus is achieved, thanks to a few simple pieces skillfully juxtaposed but independent of each other, a non-deformable cage C which ensures the frictionless movements of the arm 2 in the bore 3, and which also serves as a connection between the internal stop
19 secured to the arm 2, on which the spring 5 rests, and the outer stop 20 secured to the bore 3.

Dans l'exemple de réalisation représenté aux figures 4 et 5 on retrouve la cage C située à l'extrémité interieure du bras 2, qui est cet fois un tube de section circulaire, coulissant dans l'alésage radial 3 de section carrée dii moyeu 4 et dont le diamètre extérieur est inférieur aux dimen vas intérieures de l'alésage 3. Au delà de la butée intérieure 21 le tube 2 porte deux axes perpendiculaires 22 et 23 pour deux galets en croix superposés 24 et 25.In the embodiment shown in Figures 4 and 5 we find the cage C located at the inner end of the arm 2, which is this time a tube of circular section, sliding in the radial bore 3 of square section dii hub 4 and the outside diameter of which is less than the internal dimensions of the bore 3. Beyond the internal stop 21 the tube 2 carries two perpendicular axes 22 and 23 for two superimposed cross rollers 24 and 25.

Des entretoises- tubulaires 26 maintiennent les galets 24 et 25 centrés de telle sorte que leurs surfaces de roulement 27 bisautées à 450 de part et d'autre du plan médian desdits galets collaborent selon les diagonales de l'alésage avec les quatre zones angulaires de l'alésage 3
Des lumières 26 ont été prévues dans le tube 2 pour le passage des galets 24 et 25 dans et hors dudit tube 2 et pour permettre leur contact tangentiel avec les zones angulaires de l'alésage 3.Tubular spacers 26 keep the rollers 24 and 25 centered so that their running surfaces 27 bevelled at 450 on either side of the median plane of said rollers collaborate along the diagonals of the bore with the four angular zones of the bore 3
Lights 26 have been provided in the tube 2 for the passage of the rollers 24 and 25 in and out of the said tube 2 and to allow their tangential contact with the angular zones of the bore 3.

Comme on le réalise aisément en particulier à l'examen de la figure 5, les galets 24 et 25 assurent simultanément la suppression des frottements parasites entre le tube 2 et l'alésage 3 et le blocage en rotation du tube dans l'alésage, son guidage longitudinal étant assuré par la butée extérieure 29 solidaire de l'alésage 3. As can easily be seen in particular on examining FIG. 5, the rollers 24 and 25 simultaneously ensure the suppression of parasitic friction between the tube 2 and the bore 3 and the rotation blocking of the tube in the bore, its longitudinal guide being provided by the external stop 29 integral with the bore 3.
