Description

SYSTEME DE CHENILLAGE POUR VEHICULE ROULANT TRACKING SYSTEM FOR A ROLLING VEHICLE
La présente invention a pour objet un système de montage d'une chenille adaptée aux sols meubles autour des roues de la plupart des véhicules roulants.The present invention relates to a system for mounting a track adapted to loose soil around the wheels of most rolling vehicles.
On a décrit dans le brevet français 98 03231 déposé le 17 mars 1998 au nom de la demanderesse pour "une bande de roulement sur sol meuble", une bande de roulement sur sol meuble disposée autour des roues avant et arrière d'un véhicule qui permette les virages par simple braquage des roues directrices et réduise grandement la friction des roues sur la bande de roulement. Il s ' est avéré q ' une telle chenille peut s ' adapter efficacement roue par roue isolément par 1 ' adjonction de poulies d'appui au sol, solidaires des axes des roues du véhicule, lesdites poulies étendant la chenille de part et d'autre desdites roues, ce qui a pour effet d'augmenter la surface de contact du véhicule sur le sol, indépendamment de la largeur de la chenille.We have described in French patent 98 03 231 filed on March 17, 1998 in the name of the applicant for "a tread on soft ground", a tread on soft ground arranged around the front and rear wheels of a vehicle which allows cornering by simply turning the steered wheels and greatly reducing wheel friction on the tread. It has been found that such a track can effectively adapt wheel by wheel in isolation by the addition of ground support pulleys, integral with the axes of the vehicle wheels, said pulleys extending the track on either side. said wheels, which has the effect of increasing the contact surface of the vehicle on the ground, regardless of the width of the track.
Selon l'invention, des poulies sont fixées aux extrémités de bras oscillant autour des axes desdites roues de telle façon q ' elles se maintiennent à distance constante de la roue quand elles subissent des oscillations sur sol inégal. Ainsi la charge supportée par une roue se trouve reportée en partie sur les poulies.According to the invention, pulleys are fixed to the ends of the arms oscillating around the axes of said wheels in such a way that they remain at a constant distance from the wheel when they undergo oscillations on uneven ground. Thus the load supported by a wheel is partially transferred to the pulleys.
Selon une autre caractéristique de 1 ' invention la chenille, composée de guides longitudinaux souples équipés de rouleaux, reçoit, intercalés entre lesdits rouleaux, des patins constitués de lames perpendiculaires auxdits guides, épousant le profil des roues du véhicule en longeant les flancs, la distance entre lames définie par la longueur des rouleaux restant inférieure au diamètre des poulies. Ainsi la roue du véhicule entraine la chenille par appui sur les arêtes internes des lames et ne peut donc déraper à 1 ' intérieur de la chenille ; de même la chenille ne peut patiner car ses lames pénètrent dans le sol perpendiculairement à la progression du véhicule.According to another characteristic of the invention, the track, composed of flexible longitudinal guides fitted with rollers, receives, interposed between said rollers, pads made up of blades perpendicular to said guides, conforming to the profile of the vehicle wheels along the sides, the distance between blades defined by the length of the rollers remaining less than the diameter of the pulleys. So the vehicle wheel drives the caterpillar by pressing on the internal edges of the blades and therefore cannot slip inside the caterpillar; similarly the track cannot slip because its blades penetrate into the ground perpendicular to the progression of the vehicle.
Selon une autre caractéristique de l'invention, les bras oscillants peuvent recevoir, outre les poulies prenant appui sur les lames, des galets insérés entre poulie et roue qui prennent appui sur les rouleaux des guides longitudinaux.According to another characteristic of the invention, the oscillating arms can receive, in addition to the pulleys bearing on the blades, rollers inserted between pulley and wheel which bear on the rollers of the longitudinal guides.
D' autres caractéristiques et avantages de 1 ' invention apparaîtront au cours de la description qui va suivre de modes particuliers de réalisation, donnés uniquement à titre d'exemple non limitatif, en regard des dessins qui représentent :Other characteristics and advantages of the invention will appear during the following description of particular embodiments, given solely by way of nonlimiting example, with reference to the drawings which represent:
- la figure 1, une vue de côté d' une roue équipée de bras triangulaires oscillants selon l'invention, munis de poulies selon 1 ' invention recevant une chenille à lames selon 1 ' invention ; - la figure 2, une vue en perspective des éléments composants une chenille selon l'invention, à savoir deux lames selon 1 ' invention et deux rouleaux selon 1 ' invention espacés et des guides longitudinaux selon l'invention. la figure 3, système de montage de bras selon l'invention oscillant sur la couronne d'une roue selon 1 ' invention à 1 ' aide de réas selon 1 ' invention recevant ladite couronne, ledit bras oscillant comportant, outre lesdites poulies et dits réas, des galets selon 1 ' invention destinés à prendre appui sur les rouleaux des guides longitudinaux selon l'invention.- Figure 1, a side view of a wheel fitted with oscillating triangular arms according to the invention, provided with pulleys according to the invention receiving a blade track according to the invention; - Figure 2, a perspective view of the components of a track according to the invention, namely two blades according to one invention and two rollers according to one invention spaced apart and longitudinal guides according to the invention. Figure 3, arm mounting system according to the invention oscillating on the crown of a wheel 1 according to the invention using sheaves 1 according to the invention receiving said crown, said swing arm comprising, in addition to said pulleys and said sheaves , rollers according to the invention intended to bear on the rollers of the longitudinal guides according to the invention.
- la figure 4, schéma de montage d'une chenille selon 1 ' invention sur deux roues avant et arrière d' un véhicule, équipées de bras oscillants avec poulies selon l'invention, comportant deux roulement solidaires selon 1 ' invention étranglant la chenille entre les deux roules selon 1 ' invention.- Figure 4, diagram of mounting a track according to one invention on two front and rear wheels of a vehicle, equipped with swing arms with pulleys according to the invention, comprising two integral bearings according 1 invention strangling the track between the two rollers 1 according to the invention.
Sur la figure 1, la chenille est constituée de lames 1 et guides longitudinaux 5 qui s ' adaptent au profil de la roue d'un véhicule et aux poulies 2 fixées aux extrémités de bras triangulaires oscillant autour de 1 ' axe de ladite roue. Pour la clarté du dessin il n'est représenté que le bras placé devant la roue, l'autre occupant une position symétrique derrière ladite roue. Sur la figure 2 sont représentées en perspective deux lames 1 parallèles entre elles et perpendiculaires aux deux rouleaux 6 également représentés, chacune des parties étant traversée par deux guides souples longitudinaux 5 - lames 1 et rouleaux 6 viennent en contact par tension des guides longitudinaux 5 qui peuvent être à titre d'exemple, des sangles, des courroies, des chaînes ou des câbles. La déformation latérale de la chenille s ' obtient par diminution de la tension. Une lamelle transversale 11 est représentée sur une des lames 1. Elle a pour but de pallier le glissement latéral de la roue, sur un sol à devers notamment.In FIG. 1, the track is made up of blades 1 and longitudinal guides 5 which adapt to the profile of the wheel of a vehicle and to the pulleys 2 fixed to the ends of triangular arms oscillating around the axis of said wheel. For clarity of the drawing, only the arm is placed in front of the wheel, the other occupying a symmetrical position behind said wheel. In Figure 2 are shown in perspective two blades 1 parallel to each other and perpendicular to the two rollers 6 also shown, each of the parts being traversed by two flexible longitudinal guides 5 - blades 1 and rollers 6 come into contact by tension of the longitudinal guides 5 which may be, for example, straps, belts, chains or cables. The lateral deformation of the track is obtained by reducing the tension. A transverse strip 11 is shown on one of the blades 1. Its purpose is to compensate for the lateral sliding of the wheel, in particular on sloping ground.
Sur la figure 3 sont schématisés un bras oscillant 3 et deux réas 8 sur lesquels prend appui une couronne 7 concentrique à une roue de véhicule. A titre d'exemple la couronne 7 peut être un cerclage rapporté sur la jante.In Figure 3 are shown schematically an oscillating arm 3 and two sheaves 8 on which rests a crown 7 concentric with a vehicle wheel. By way of example, the crown 7 can be a strap attached to the rim.
Sont également représentés sur cette figure des galets 9 solidaires du bras oscillant 3 et insérés entre la roue du véhicule et les poulies 2. Les galets accompagnent le défilement de la chenille en prenant appui sur les rouleaux 6.Also shown in this figure are rollers 9 secured to the swinging arm 3 and inserted between the vehicle wheel and the pulleys 2. The rollers accompany the running of the track by resting on the rollers 6.
Sur la figure 4 est représenté le passage d'une chenille autour de deux roues d'un véhicule, montées dans le même plan. Chacune desdites roues comporte des poulies 2. Entre les poulies 2 intérieures sont représentées deux roulettes 10 solidaires l'une de l'autre. La chenille passe sur une première roue du véhicule, contourne sa poulie 2 extérieure, passe sous ladite roue, s'écarte du sol en passant la roulette 10 inférieure, revient sous la poulie 2 intérieure de la seconde roue, passe sous celle-ci, contourne la seconde poulie 2 externe à la seconde roue du véhicule, passe sur cette dernière, descend et passe à l'intérieur de la roulette 10 supérieure, remonte sur la première roue du véhicule en achevant son cycle. Un tel montage permet à l'une des roues de demeurer directrice, ses propres poulies l'accompagnant dans les changements de direction. La chenille conservant une capacité de déformation latérale demeure en place, les roulettes 10 la guidant en regard des poules 2 intérieures.In Figure 4 is shown the passage of a crawler around two wheels of a vehicle, mounted in the same plane. Each of said wheels has pulleys 2. Between the inner pulleys 2 are represented two rollers 10 in solidarity with each other. The track passes over a first wheel of the vehicle, bypasses its external pulley 2, passes under said wheel, moves away from the ground by passing the lower caster 10, returns under the internal pulley 2 of the second wheel, passes under the latter, bypasses the second pulley 2 external to the second wheel of the vehicle, passes over the latter, descends and passes inside the upper caster 10, ascends to the first wheel of the vehicle by completing its cycle. Such an assembly allows one of the wheels to remain steered, its own pulleys accompanying it in the changes of direction. The track retaining a lateral deformation capacity remains in place, the rollers 10 guiding it opposite the interior hens 2.
Le système de chenillage décrit s ' adapte à toute roue de véhicule suffisamment distante des parties fixes du véhicule, châssis, carrosserie, éléments du moteur. Il peut se monter roue par roue, par exemple sur les véhicules à 4 roues motrices. "Quad" notamment, ou accouplé à deux roues avant et arrière des engins à deux roues par exemple. The tracking system described adapts to any vehicle wheel sufficiently distant from the fixed parts of the vehicle, chassis, bodywork, engine components.
