Système de chenillage pour véhicule 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 The present invention relates to a system for mounting a track adapted to loose soil around the wheels of the
plupart des véhicules roulants.most rolling vehicles.
On a décrit dans le brevet français 9803231 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 We have described in French patent 9803231 filed 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 the turns by simply turning the steering wheels and reducing
grandement la friction des roues sur la bande de roulement. greatly the friction of the wheels on the tread.
Il s'est avéré qu'une telle chenille peut s'adapter efficacement roue par roue isolément par l'adjonction de poulies d'appui au sol, solidaires des axes des roues du véhicule, les dites poulies étendant la chenille de part et d'autre des dites roues, ce qui a pour effet d'augmenter la surface de contact du véhicule sur le It turned out that such a track can be effectively adapted wheel by wheel in isolation by the addition of ground support pulleys, integral with the axes of the vehicle wheels, the said pulleys extending the track from and other of the said wheels, which has the effect of increasing the contact surface of the vehicle on the
sol, indépendamment de la largeur de la chenille. ground, regardless of the width of the track.
Selon l'invention, des poulies sont fixées aux extrémités de bras oscillant autour des axes des dites roues de telle façon qu'elles se maintiennent à distance constante de la roue quand elles subissent des oscillations sur sol inégal. Ainsi la charge supportée 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
par une roue se trouve reportée en partie sur les poulies. by a wheel is partially transferred to the pulleys.
Selon une autre caratéristique de l'invention la chenille, composée de guides longitudinaux souples équipés de rouleaux, reçoit, intercallés entre les dits rouleaux, des patins constitués de lames perpendiculaires aux dits 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 entraîne la chenille par appui sur les arêtes internes des lames et ne peut donc déraper à l'intérieur de la chenille; de même la chenille ne peut patiner car ses lames pénètrent dans le sol According to another characteristic of the invention, the track, composed of flexible longitudinal guides fitted with rollers, receives, interposed between the said rollers, pads made up of blades perpendicular to the said guides, conforming to the profile of the wheels of the vehicle along the sides, the distance between blades defined by the length of the rollers remaining less than the diameter of the pulleys. Thus, the vehicle wheel drives the track by pressing on the internal edges of the blades and therefore cannot slip inside the track; similarly the caterpillar cannot skate because its blades penetrate the ground
perpendiculairement à la progression du véhicule. perpendicular to the progress 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 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
rouleaux des guides longitudinaux.rollers of the longitudinal guides.
