Abstract
Description
Dans la demande de brevet principal déposée le 24 novembre 1978 sous le nO 78.33217, on a décrit un véhicule agricole constitué par l'assemblage l'un derrière l'autre : d'une part, d'un élément de traction comportant une cabine, un moteur et un train à la fois moteur et directeur ; d'autre part, d'un élément porteur constitué par une plate-forme munie de moyens de sustentation par effet de sol et comportant un dispositif anti-dérapant. In the main patent application filed on November 24, 1978 under No. 78.33217, an agricultural vehicle has been described consisting of the assembly one behind the other: on the one hand, of a traction element comprising a cabin, an engine and a train both engine and director; on the other hand, a carrier element constituted by a platform provided with means of lift by ground effect and comprising an anti-slip device.
On a en particulier décrit en relation avec les figures 4 et ; un tel véhicule constitué de deux parties distinctes articulées l'une à l'autre soit par un axe vertical, soit par un joint de cardan. We have in particular described in relation to FIGS. 4 and; such a vehicle consisting of two distinct parts articulated to each other either by a vertical axis or by a universal joint.
Dans la demande de ler certificat d'addition déposée le 24 janvier 1979 sous le nO 79.01757, on a décrit un perfectionnement à ce véhicule selon lequel l'élément de traction et l'élément de sustentation sont indépendants l'un de l'autre, mais attelés l'un à l'autre par des moyens rendant la plate-forme solidaire de l'élément moteur au point de vue de la traction, mais indépendante au point de vue de son assiette. In the application for the certificate of addition filed on January 24, 1979 under No. 79.01757, an improvement has been described to this vehicle according to which the traction element and the lift element are independent of each other, but coupled to each other by means making the platform integral with the motor element from the point of view of traction, but independent from the point of view of its attitude.
En particulier, on a décrit un attelage reliant l'élément moteur à l'élément de sustentation constitué par un timon dont une extrémité est articulée à l'élément moteur par l'intermédiaire d'un axe vertical et dont l'autre extrémité est fixée à la plate-forme par une rotule placée à proximité du ou au centre de poussée des moyens de sustentation. In particular, a coupling has been described connecting the motor element to the lift element constituted by a drawbar, one end of which is articulated to the motor element by means of a vertical axis and the other end of which is fixed. to the platform by a ball joint placed close to or at the center of thrust of the lifting means.
Cependant, il s'est avéré que ces moyens d'attelage ne donnaient pas satisfaction. However, it turned out that these coupling means were not satisfactory.
Selon la présente addition l'élément moteur et l'élément de sustentation sont attelés l'un à l'autre par un dispositif d'attelage comportant deux axes de rotation horizontaux, perpendiculaires. According to the present addition, the driving element and the lifting element are coupled to each other by a coupling device comprising two horizontal, perpendicular axes of rotation.
A titre d'exemple non limitatif et pour faciliter la compréhension de l'invention, on a représenté aux dessins annexés :
Figure 1, une vue schématique en élévation latérale d'un premier mode de réalisation
Figure 2, une vue schématique en plan de la figure 1;
Figure 3, une vue schématique en élévation latérale d'un deuxième mode de réalisation
Figure 4, une vue schématique en plan de la figure 3.By way of nonlimiting example and to facilitate understanding of the invention, the accompanying drawings show:
Figure 1, a schematic side elevational view of a first embodiment
Figure 2, a schematic plan view of Figure 1;
Figure 3, a schematic side elevational view of a second embodiment
Figure 4, a schematic plan view of Figure 3.
Sur ces quatre figures les éléments identiques à ceux décrits au brevet principal et à sa première addition portent les mêmes références et ne sont pas décrits à nouveau. In these four figures, the elements identical to those described in the main patent and in its first addition bear the same references and are not described again.
En se reportant aux figures 1 et 2, on voit que lté- lément moteur A et l'élément de sutentation B sont complètement séparés l'un de l'autre et attelés l'un à l'autre par un dispositif 14. Ce dispositif 14 comporte deux branches symétriques 15 qui comportent chacune, à leur extrémité, un tourillon 16. Ces tourillons 16 sont alignés l'un par rapport à l'autre et définissent un axe XX' qui est perpendiculaire à l'axe longitudinal YY' du véhicule et est situé pratiquement au milieu de l'élément porteur muni de moyens 5 de sustentation par effet de sol. Il en résulte que ledit élément porteur peut pivoter autour de l'axe XX' par rapport au dispositif d'attelage 14. Referring to Figures 1 and 2, it can be seen that the motor element A and the sutentation element B are completely separated from each other and coupled to each other by a device 14. This device 14 comprises two symmetrical branches 15 which each have, at their end, a pin 16. These pins 16 are aligned with respect to each other and define an axis XX 'which is perpendicular to the longitudinal axis YY' of the vehicle and is located practically in the middle of the carrier element provided with means 5 of lift by ground effect. As a result, said carrier element can pivot about the axis XX 'relative to the coupling device 14.
Les deux branches 15 dudit dispositif d'attelage 14 se réunissent en une seule branche 17, située sur l'axe YY' et l'extrémité de cette branche 17 tourillonne dans une chape 18, solidaire de l'élément de traction, tout en étant bloquée longitudinalement par tout moyen connu et donc non décrit de façon détaillée. Il en résulte que ledit élément de traction peut pivoter autour de l'axe YY' par rapport au dispositif d'attelage 14, mais ne peut pas glisser le long de cet axe. The two branches 15 of said coupling device 14 come together in a single branch 17, located on the axis YY 'and the end of this branch 17 journals in a yoke 18, integral with the traction element, while being blocked longitudinally by any known means and therefore not described in detail. As a result, said traction element can pivot about the axis YY 'relative to the coupling device 14, but cannot slide along this axis.
Les figures 3 et 4 représentent une variante dans laquelle les mêmes éléments portent les mêmes références. Figures 3 and 4 show a variant in which the same elements have the same references.
Dans cette disposition les moyens de sustentation 5 sont placés à l'intérieur d'un capotage 19 qui est muni de prises d'air latérales 20. Cette disposition permet de disposer des charges sur la surface plane supérieure 19a du capotage 19.In this arrangement, the lifting means 5 are placed inside a cowling 19 which is provided with lateral air intakes 20. This arrangement allows loads to be placed on the upper flat surface 19a of the cowling 19.
D'autre part, dans ce cas les deux branches 15 encadrent extérieurement, de chaque côté ltélément porteur.On the other hand, in this case the two branches 15 frame externally, on each side ltélément carrier.
Les deux axes XX' et YY' peuvent être dans le même plan, comme cela est représente à la figure 3 ou dans des plans différents comme cela est représenté à la figure 1. The two axes XX 'and YY' can be in the same plane, as shown in Figure 3 or in different planes as shown in Figure 1.
Bien que cela ne soit pas representé, les éléments porteurs représentés aux figures 1 à 4 peuvent comporter un dispositif antidérapant analogue au dispositif 13 du brevet principal. Although not shown, the load-bearing elements shown in FIGS. 1 to 4 may include a non-slip device similar to the device 13 of the main patent.
D'autre part, les moyens de sustentation 5 peuvent être entrainés, soit par le moteur 2, soit par des moteurs indépendants. On the other hand, the lift means 5 can be driven, either by the motor 2, or by independent motors.
