Abstract
Description
Ta présente invention a pour objet une commande de direction à distance pour machines agricoles tractees ou poussées par un tracteur. Plus précisément cette commande a pour objet de facilite le guidage desdites machines lors de leur utilisation en asservissant leurs roues directrices à la direction du tracteur qui les remorque ou les pousse. Par exemple on utilise des machines dispo sées devant un tracteur soit pour labourer la terre, soit pour l'aplanir, quelquefois pour effectuer les deux opérations en même temps. Dans tous ces cas il est trés difficile de diriger lesdites machines afin qu'elles restent parfaitement en ligne.Your present invention relates to a remote steering control for agricultural machines towed or pushed by a tractor. More specifically, the purpose of this command is to facilitate the guiding of said machines during their use by slaving their steered wheels to the direction of the tractor which tows or pushes them. For example, machines are used in front of a tractor either to plow the soil or to level it, sometimes to carry out the two operations at the same time. In all these cases it is very difficult to direct said machines so that they remain perfectly in line.
De même il est malaise de virer ou de travailler en courbe avec ces nachines agricoles.Similarly it is uncomfortable to turn or work in a curve with these agricultural nachines.
la présente invention à pour objet de remédier à ces inconvénients en asservissant la direction ou les roues directrices de ces machines agricoles à la direction du tracteur.the object of the present invention is to remedy these drawbacks by slaving the steering or the steered wheels of these agricultural machines to the direction of the tractor.
La présente invention consiste à monter un vérin double effet sous le pont avant du tracteurs et un second vérin double effet sur les roues directrices de la machine agricole et a. les raccordei en parallèle, le second verin étant commandé par le premier.The present invention consists in mounting a double-acting cylinder under the front axle of the tractors and a second double-acting cylinder on the steering wheels of the agricultural machine and a. the connections in parallel, the second cylinder being controlled by the first.
La présente invention sera mieux comprise à la lecture de la description qui suit et à 11 examen du dessin annexe sur lequel on a. représenté schématiquement une des réalisations préférée de l'invention.The present invention will be better understood on reading the description which follows and on examining the annexed drawing on which there is. schematically shown one of the preferred embodiments of the invention.
Sur cette figure on a repésenté schématiquement, et vu par dessous, un pont avant t de tracteur avec ses deux roues 2, d'une part, et deux roues directrices 3 d'une machine agricole 4 quelconque "poussée" par le tracteur, d'autre part.In this figure we have schematically represented, and seen from below, a front axle t of a tractor with its two wheels 2, on the one hand, and two steered wheels 3 of any agricultural machine 4 "pushed" by the tractor, d 'somewhere else.
De chaque côté du pont avant I du tracteur entre l'axe de pivotemer 5 des roues 2 et le flasque de roue 6, on a fixé sur la fusée pivotante 7 de chaque roue 2, deux plaques métalliques 8A-8B portant chacune un axe 9 destiné à recevoir chaque extrémité lOA-lOB d'un vérin double effet 10, disposé entre ces plaques 8A-8B.On each side of the front axle I of the tractor between the pivot axis 5 of the wheels 2 and the wheel flange 6, two metal plates 8A-8B each carrying an axis 9 were fixed on the pivoting spindle 7 of each wheel 2 intended to receive each end lOA-lOB of a double-acting cylinder 10, disposed between these plates 8A-8B.
Ta plaque SA, par exemple, est direigée vers l'avant du tracteur et la plaque SB vers l'arriére de maniére que le vérin 10 soit incliné par rapport à l'axe X-X de la direction.Your plate SA, for example, is pointed towards the front of the tractor and the plate SB towards the rear so that the jack 10 is inclined relative to the axis X-X of the steering.
Un vérin double effet identique 11 est disposé sur la direction de la machine à guider 4 du façon identique à celui du tracteur au moyen de plaques 12A-12B, portant des axes 13, fixées sur la fusée pivotante 14 des roues 3, le vérin 11 étant incline en sens inverse du vérin 10 par rapport à l'axe Y-Y des roues 3.An identical double-acting cylinder 11 is arranged on the direction of the guiding machine 4 in the same way as that of the tractor by means of plates 12A-12B, carrying axes 13, fixed on the pivoting spindle 14 of the wheels 3, the cylinder 11 being inclined in the opposite direction of the jack 10 relative to the axis YY of the wheels 3.
Les vérins 10 et il sont raccordés en parallèle au moyen de deux canalisations souples 15-16 de type connu.Ce montage permet un braquage des roues 3 identique au braquage des roues 2 lorsque l'on agit sur la direction du tracteur, le vérin 10 servant de nompe en envoyant le fluide dans le vérin 11.The jacks 10 and it are connected in parallel by means of two flexible pipes 15-16 of known type. This assembly allows the turning of the wheels 3 identical to the turning of the wheels 2 when the direction of the tractor is acted on, the jack 10 serving as nompe by sending the fluid into the jack 11.
Le réglage de la course s'effectue de la maniére suivante et très simplement:on braque les roues 2 du tracteur de maniére qu'elles viennent en butéeet ensuite on agit sur la tige filetée lOB du vérin 10 afin que le piston lOC ne soit pas en bout de course pour avoir une garde de quelques millimétres.The stroke adjustment is carried out in the following way and very simply: the wheels 2 of the tractor are turned so that they come to a stop and then action is taken on the threaded rod lOB of the jack 10 so that the piston lOC is not at the end of the race to have a guard of a few millimeters.
Cette commande de direction permet Ie guidage de machines agricoles "poussées" par un tracteur mais aussi le guidage de machines tractées sans modification du tracteur et assure de façon correcte leur maintien en ligne.This direction command allows Ie guiding of agricultural machinery "pushed" by a tractor but also the guiding of towed machines without modification of the tractor and ensures their correct keeping in line.
Bien entendu le vérin commandé li peut être monte de maniére différente, par exemple, sur un point fixe du bdti de la machine à guider d'une part, et sur la fusée pivotante d'une des roues d'autre part. Of course, the actuated cylinder li can be mounted in a different manner, for example, on a fixed point of the bdti of the machine to be guided on the one hand, and on the pivoting spindle of one of the wheels on the other hand.
