Abstract
Description
Tracteur enlambeur arrière surélevé
La présente invention se rapporte aux tracteurs enj ambeurs. Raised rear straddle tractor
The present invention relates to high clearance tractors.
Dans la demande de brevet n' 85.1819e déposée le 9/12/1985 au nom de la demanderesse, on a décrit un tracteur enjambeur comportant deux jambes arrière portant les roues arrière motrices, ces deux Jambes étant reliées l'une & l'autre par une ou plusieurs poutres transversales situées en dessous du niveau du moteur et de la cabine de pilotage, les deux jambes avant étant prolongées vers le haut et reliées l'une à l'autre à leur sommet. Cette disposition a pour effet de permettre de faire pénétrer à l'intérieur du châssis enjambeur par l'avant du tracteur des outils agricoles de grande hauteur. In patent application No. 85.1819e filed on 9/12/1985 in the name of the applicant, a straddle tractor has been described comprising two rear legs carrying the rear driving wheels, these two legs being connected to each other by one or more transverse beams located below the level of the engine and the cockpit, the two front legs being extended upwards and connected to each other at their top. The effect of this arrangement is to allow agricultural implements of great height to penetrate inside the straddle chassis from the front of the tractor.
Il s'avère cependant que ces outils ne peuvent pas, dans certains cas, pénétrer suffisamment à l'intérieur du châssis à cause de la présence du poste de pilotage et du moteur. However, it turns out that these tools cannot, in certain cases, penetrate sufficiently inside the chassis because of the presence of the cockpit and the engine.
Dans la demande de brevet n 87.el4el déposee le 5/2/1987 au nom du même demandeur, on a décrit un tracteur enjambeur dont les deux roues avant et une roue arrière sont fixes, tandis que l'autre roue arrière est réglable latéralement, ce tracteur étant caractérisé par le fait que ladite roue arrière mobile est portée par un caisson sensiblement horizontal, articulé a un caisson sensiblement vertical, ce dernier étant porté par des moyens lui permettant de coulisser latéralement par rapport au chassis du tracteur. In patent application No. 87.el4el filed on 5/2/1987 in the name of the same applicant, a straddle tractor has been described in which the two front wheels and one rear wheel are fixed, while the other rear wheel is adjustable laterally , this tractor being characterized in that said movable rear wheel is carried by a substantially horizontal box, articulated to a substantially vertical box, the latter being carried by means allowing it to slide laterally relative to the chassis of the tractor.
La présente invention a pour objet un perfectionnement à ce type de tracteur selon lequel les moyens permettant de faire coulisser le caisson vertical sont surélevés de façon que l'on puisse faire passer dessous un outil agricole qui est ainsi introduit sur le côté du tracteur et entre les deux roues arrière motrices. The subject of the present invention is an improvement to this type of tractor according to which the means making it possible to slide the vertical box are raised so that an agricultural implement can be passed underneath which is thus introduced on the side of the tractor and between the two rear-wheel drive.
A titre d'exemple non limitatif et pour faciliter la compréhension de l'invention, on a représenté aux dessins annexés
Figure 1 une vue de face d'un exemple de réalisation d'un tracteur enjambeur selon l'invention
Figure 2 une vue en plan du tracteur enjambeur représenté à la figure 1
Figure 3 une vue en élévation latérale avec arraché partiel d'un tracteur enjambeur des figures 1 et 2.By way of nonlimiting example and to facilitate understanding of the invention, there is shown in the accompanying drawings
Figure 1 a front view of an embodiment of a straddle tractor according to the invention
Figure 2 a plan view of the straddle tractor shown in Figure 1
Figure 3 a side elevational view with partial cutaway of a straddle tractor of Figures 1 and 2.
En se reportant à ces figures, on voit que le châssis 1 du tracteur est constitué par deux caissons latéraux 2a, 2b, le caisson de gauche 2b portant une jambe arrière 3 et une jambe avant 4b. La jambe avant 4b porte la roue avant 6b ; tandis que la jambe arrière 3 porte la roue arrière 5b. Referring to these figures, it can be seen that the chassis 1 of the tractor is constituted by two lateral boxes 2a, 2b, the left box 2b carrying a rear leg 3 and a front leg 4b. The front leg 4b carries the front wheel 6b; while the rear leg 3 carries the rear wheel 5b.
Le caisson 3 peut etre creux et porter les moyens mécaniques tels que des pignons et chaînes entraînant la roue arrière motrice 5b ; il peut également porter un moteur hydraulique entraînant ladite roue arrière 5b. The box 3 can be hollow and carry mechanical means such as sprockets and chains driving the rear drive wheel 5b; it can also carry a hydraulic motor driving said rear wheel 5b.
Le deuxième caisson latéral 2a porte uniquement la jambe avant 4a et la roue avant 6a. The second lateral box 2a carries only the front leg 4a and the front wheel 6a.
Comme cela a été décrit dans la demande de brevet n 87.141 , l'autre roue arrière 5a est portée par un caisson sensiblement horizontal 18 articulé par un pivot 17 à un caisson sensiblement vertical 13 qui est porté par deux tubes parallèles, horizontaux 11 qui coulissent de façon télescopique dans deux tubes 7. As described in patent application No. 87.141, the other rear wheel 5a is carried by a substantially horizontal box 18 articulated by a pivot 17 to a substantially vertical box 13 which is carried by two parallel, horizontal tubes 11 which slide telescopically in two tubes 7.
Selon la présente invention, les deux tubes 7 sont fixés non pas aux deux caissons latéraux 2a et 2b mais au sommet de deux montants latéraux 14a et 14b fixés auxdits caissons latéraux 2a et 2b. According to the present invention, the two tubes 7 are fixed not to the two lateral boxes 2a and 2b but to the top of two lateral uprights 14a and 14b fixed to said side boxes 2a and 2b.
De préférence, comme cela est représenté, les deux montants 14a et 14b le sont d'une hauteur telle que les deux tubes 7 passent au-dessus du moteur, le caisson 13 ayant une longueur correspondante. Preferably, as shown, the two uprights 14a and 14b are so high that the two tubes 7 pass over the engine, the box 13 having a corresponding length.
Les moyens d'entraînement de la roue 5a portés par le caisson 13 sont analogues à ceux décrits dans la demande de brevet n' 87.1481 et ne sont donc pas décrits à nouveaux. Ils sont constitues soit par des ensembles de chaînes et de pignon, soit par un moteur hydraulique porté par le caisson 18. The drive means of the wheel 5a carried by the box 13 are similar to those described in patent application No. 87.1481 and are therefore not described again. They are formed either by sets of chains and sprocket, or by a hydraulic motor carried by the box 18.
Le pivotement du caisson 18 autour du pivot 17 est commandé par un vérin 23. Le coulissement des tubes 11 dans les tubes 7 est également commandé par un vérin. The pivoting of the box 18 around the pivot 17 is controlled by a jack 23. The sliding of the tubes 11 in the tubes 7 is also controlled by a jack.
Cette disposition permet de fixer un outil agricole sur le côté du chassis 1, tout en le faisant passer en dessous du portique constitué par le caisson 13, le montant latéral 14a et les tubes 7-11 de sorte que ledit outil se trouve entre les deux roues motrices 5a et 5b. This arrangement makes it possible to fix an agricultural tool on the side of the chassis 1, while passing it below the gantry formed by the box 13, the lateral upright 14a and the tubes 7-11 so that said tool is located between the two driving wheels 5a and 5b.
Comme décrit dans la demande de brevet n' 87.141, le pivot 17 peut etre placé soit à l'avant, soit à l'arrière du caisson 18. As described in patent application No. 87,141, the pivot 17 can be placed either at the front or at the rear of the box 18.
