Description
s Tracteur, notamment pour travaux agrairess Tractor, particularly for agricultural work
La présente invention concerne un tracteur, notamment pour travaux agraires, du type comprenant, un châssis porteur roulant surmonté d'un poste de pilotage et équipé d'au moins un attelage trois points à bras relevables. 10 Jusqu'à présent, les tracteurs sont équipés pour l'essentiel d'un moteur thermique pour leur avancement. Le prix élevé des carburants et le bruit du moteur amènent aujourd'hui à réfléchir à d'autres solutions qui permettraient de réduire la pollution engendrée et le bruit sans nuire aux performances du 15 véhicule tracteur. The present invention relates to a tractor, particularly for agricultural work, of the type comprising, a rolling carrier chassis surmounted by a cockpit and equipped with at least one three-point linkage arm lift. Until now, the tractors are essentially equipped with a heat engine for their advancement. The high price of fuels and the noise of the engine lead today to think of other solutions that would reduce pollution and noise without affecting the performance of the towing vehicle.
Un but de la présente invention est donc de proposer un tracteur, notamment pour travaux agraires, dont la conception permet de réduire la pollution et le bruit par comparaison à un tracteur thermique, sans nuire aux performances du 20 tracteur. An object of the present invention is therefore to provide a tractor, particularly for agricultural work, the design of which reduces pollution and noise compared to a heat tractor, without harming the performance of the tractor.
A cet effet, l'invention a pour objet un tracteur, notamment pour travaux agraires, du type comprenant, un châssis porteur roulant surmonté d'un poste de pilotage et équipé d'au moins un attelage trois points à bras relevables, 25 caractérisé en ce que les roues du châssis et le dispositif de relevage de l'attelage trois points sont animés à partir d'une source d'énergie électrique portée par le châssis pour la mise en oeuvre des organes moteurs de déplacement agissant sur les roues et le dispositif de relevage. For this purpose, the subject of the invention is a tractor, particularly for agricultural work, of the type comprising a rolling chassis surmounted by a cockpit and equipped with at least one three-point hitch with liftable arms, characterized in that the chassis wheels and the hitching device of the three-point hitch are driven from a source of electrical power carried by the chassis for the implementation of the drive members acting on the wheels and the device lift.
30 La possibilité d'actionner d'une part le dispositif de relevage de l'attelage trois points, d'autre part les organes moteurs de déplacement du tracteur à partir d'une source d'énergie électrique permet de réduire grandement la pollution engendrée par le tracteur ainsi que le bruit produit par un tel tracteur. i0 20 2 L'invention sera bien comprise à la lecture de la description suivante d'exemples de réalisation, en référence aux dessins annexés dans lesquels : la figure 1 représente une vue schématique en perspective d'un tracteur s conforme à l'invention, les figures 1 bis et 1 ter représentent le tracteur de la figure 1 sans la carrosserie ; la figure 2 représente une vue de côté du tracteur représenté à la figure 1, la figure 3 représente une vue de dessous du tracteur représenté à la figure 1 ; The possibility of actuating on the one hand the lifting device of the three-point hitch, on the other hand the driving members for moving the tractor from a source of electrical energy can greatly reduce the pollution generated by the tractor and the noise produced by such a tractor. The invention will be better understood on reading the following description of exemplary embodiments, with reference to the appended drawings in which: FIG. 1 represents a schematic perspective view of a tractor according to the invention, Figures 1a and 1b show the tractor of Figure 1 without the body; Figure 2 shows a side view of the tractor shown in Figure 1, Figure 3 shows a bottom view of the tractor shown in Figure 1;
la figure 4 représente une vue partielle en perspective d'une roue d'un 15 sous-ensemble d'une paire de roues équipant les trains avant et arrière, une seule roue ayant été représentée ; FIG. 4 shows a partial perspective view of a wheel of a subset of a pair of wheels fitted to the front and rear axles, with only one wheel being shown;
la figure 5 représente une vue en perspective d'un sous-ensemble de roue équipant le train central du tracteur et la figure 6 représente une roue avec la section du pneumatique. Figure 5 shows a perspective view of a wheel subassembly equipping the central train of the tractor and Figure 6 shows a wheel with the section of the tire.
Comme mentionné ci-dessus, le tracteur 1, objet de l'invention, est plus particulièrement destiné à la réalisation de travaux agraires, en particulier par 25 coopération avec une machine de traitement ou de travail du sol, telle que déchaumeuse, ameublisseur, charrue ou autre attelé au véhicule tracteur. As mentioned above, the tractor 1, object of the invention, is more particularly intended for the realization of agricultural work, in particular by cooperation with a processing machine or tillage, such as dethatcher, loosener, plow or other coupled to the towing vehicle.
Ce tracteur 1 comprend un châssis 2 porteur roulant surmonté d'un poste 3 de pilotage. Ce châssis 2 est encore équipé, à l'avant et/ou à l'arrière du châssis, 30 d'un attelage 4 trois points à bras relevables. De manière traditionnelle, cet attelage 4 trois points comporte deux bras relevables et une barre de poussée. Le relevage des bras est obtenu généralement par actionnement d'un vérin électrique dont le moteur (non représenté) est alimenté en énergie.à partir de la source d'énergie électrique portée par le châssis 2 et servant en parallèle à l'alimentation des organes 13 moteurs de déplacement agissant sur les roues 10 de l'engin et pilotés par des variateurs 16A. This tractor 1 comprises a chassis 2 rolling carrier surmounted by a station 3 driving. This chassis 2 is further equipped, at the front and / or rear of the chassis, with a hitch 4, three points with folding arms. In the traditional way, this four-point hitch 4 comprises two lift arms and a push bar. The raising of the arms is generally obtained by actuation of an electric cylinder whose motor (not shown) is supplied with energy from the source of electrical energy carried by the frame 2 and serving in parallel to the supply of organs 13 displacement motors acting on the wheels 10 of the machine and driven by 16A drives.
Ce tracteur peut également être équipé d'une prise de force électrique avant et/ou arrière. Attelage trois points et prise de force sont des équipements permettant au véhicule tracteur d'être associé à une machine de travail ou de traitement du sol. De la même manière, les roues 10 du châssis 2 sont animées en déplacement à partir d'une source d'énergie électrique portée par le châssis 2, cette source d'énergie servant à la mise en fonction des organes 13 moteurs io de déplacement agissant sur les roues 10. Le détail de ces organes moteurs sera fourni ci-après. This tractor can also be equipped with a front and / or rear power take-off. Three-point hitch and PTO are equipment that enables the towing vehicle to be associated with a working or ground-handling machine. In the same way, the wheels 10 of the chassis 2 are driven in motion from a source of electrical energy carried by the chassis 2, this power source serving to put into operation the moving motors 13 on the wheels 10. The details of these driving members will be provided below.
Dans l'exemple représenté, le châssis 2 est équipé d'au moins deux trains 6, 7 de roues moteurs disposés l'un, représenté en 6, à l'avant, l'autre, représenté is en 7, à l'arrière du châssis 2. Ce châssis 2 comporte encore un train 8 de roues, de préférence non moteur, disposé entre les trains de roues avant 6 et arrière 7 moteurs. Le train de roues central 8 est de préférence disposé sensiblement à mi-distance des trains de roues avant 6 et arrière 7 moteurs. En déplacement sur une ligne droite, les roues 10 des différents trains 6, 7, 8 de 20 roues sont disposées en quinconce, de manière à obtenir un effet de damage du sol sans formation de sillons. La multiplication des roues et leur disposition permettent ainsi de réduire la force d'appui au sol de chaque roue prise individuellement. Il en résulte une réduction de la pression au cm2, ce qui est plus favorable aux cultures. 25 Chaque train de roues avant 6 et arrière 7 est formé d'une pluralité de roues 10 motrices et directrices organisées de préférence par groupe, en particulier par paire et associées individuellement ou par groupe à une commande directionnelle depuis le poste de pilotage. Chaque roue ou groupe de roues 10 30 peut ainsi pivoter autour d'un axe 9 sensiblement vertical, la direction de pivotement étant inversée d'un train 6 de roues à un autre 7 pour faciliter les manoeuvres directionnelles, notamment en bout de champ par réduction du rayon de braquage. Cette inversion des directions de pivotement d'un train 6 de roue à un autre 7 est plus particulièrement visible à la figure 3 où l'entraînement en rotation des roues du train 6 avant vers le haut de la feuille, dans la figure 3, s'accompagne d'une rotation, vers le bas de la feuille, des roues du train 7 arrière, les roues du train de roues 8 centrales demeurant alignées avec l'axe longitudinal du châssis. In the example shown, the chassis 2 is equipped with at least two trains 6, 7 of motor wheels arranged one, shown at 6, at the front, the other, shown is at 7, at the rear 2. This chassis 2 further comprises a wheel train 8, preferably non-motor, arranged between the front wheels 6 and rear 7 engines. The central wheel set 8 is preferably disposed substantially midway between the front wheels 6 and rear 7 engines. Moving in a straight line, the wheels 10 of the various trains 6, 7, 8 of 20 wheels are arranged in staggered rows, so as to obtain a soil tamping effect without formation of grooves. The multiplication of the wheels and their arrangement thus make it possible to reduce the ground support force of each wheel taken individually. This results in a reduction of the pressure to cm2, which is more favorable to crops. Each front and rear wheelset 7 is formed of a plurality of drive and steerable wheels preferably organized in groups, in particular in pairs and associated individually or in groups with directional control from the cockpit. Each wheel or group of wheels 10 can thus pivot about a substantially vertical axis 9, the pivoting direction being reversed from one set of wheels 6 to another 7 to facilitate directional maneuvers, particularly at the end of the field by reduction. steering radius. This reversal of the pivoting directions of a wheel train 6 to another 7 is more particularly visible in FIG. 3, where the rotation of the wheels of the front gear 6 towards the top of the sheet in FIG. accompanied by a rotation towards the bottom of the sheet, the wheels of the rear train 7, the wheels of the central wheel train 8 remaining aligned with the longitudinal axis of the frame.
Dans les exemples représentés, chaque train de roues avant 6 et arrière 7 est formé d'au moins deux paires de roues 10 motrices et directrices. Chaque roue ou groupe de roues d'un train moteur est porté par une fourche 11 pivotante autour dudit axe 9 de direction. Cette fourche 11 est associée à une platine io formant bras 12 de suspension et portant un moteur 13, tel qu'un moteur électrique synchrone, et un organe 14 de transmission, tel qu'un réducteur, agissant sur l'arbre 15 d'entraînement de roues. La fourche 11 et le bras 12 de suspension forment un ensemble qui est entraîné à pivotement autour de l'axe 9 de direction par l'intermédiaire d'un système pignon 18/crémaillère 19, 15 l'engrènement du pignon avec la crémaillère provoquant une rotation de l'ensemble par rapport au châssis 2 porteur autour de l'axe 9 vertical. In the examples shown, each front and rear wheelset 7 is formed of at least two pairs of driving and steering wheels. Each wheel or group of wheels of a motor train is carried by a fork 11 pivoting about said axis 9 direction. This fork 11 is associated with a plate 10 forming a suspension arm 12 and carrying a motor 13, such as a synchronous electric motor, and a transmission member 14, such as a gearbox, acting on the drive shaft 15. of wheels. The fork 11 and the suspension arm 12 form an assembly which is pivotally driven about the steering axis 9 by means of a pinion system 18 / rack 19, the meshing of the pinion with the rack causing a rotation of the assembly relative to the carrier frame 2 around the vertical axis 9.
Il doit être noté que chaque roue ou groupe de roues peut être monté réglable en hauteur sur ledit châssis. 20 L'exemple des figures 4 et 5 ne constitue qu'un exemple où chaque roue 10 ou groupe de roues d'un train de roues du châssis 2 est équipée d'un bras 12 de suspension oscillant pour suivre le profil du sol. D'autres modes de réalisation de l'ensemble, formé d'un bras 12 de suspension et d'une fourche 11, peuvent 25 être envisagés. Dans l'exemple représenté, chaque roue 10 ou groupe de roues 10 est positionné en porte à faux à l'extrémité du bras 12 de suspension pour constituer indifféremment une roue tirée ou poussée lors des déplacements du véhicule tracteur. Ce bras 12 de suspension est relié, comme l'illustrent les figures 4 et 5, à l'une de ses extrémités, à l'arbre 15 30 d'entraînement d'une roue ou d'un groupe de roues de l'engin tandis que son autre extrémité est reliée par une articulation 17 à la fourche 11 pivotant autour d'un axe vertical. Un amortisseur 20, tel qu'un ressort, est positionné entre bras 12 et fourche 11 pour permettre au bras 12 de suspension d'osciller en suivant le profil du sol. It should be noted that each wheel or group of wheels can be mounted height-adjustable on said frame. The example of FIGS. 4 and 5 is only one example where each wheel 10 or group of wheels of a wheel set of the chassis 2 is equipped with an oscillating suspension arm 12 to follow the profile of the ground. Other embodiments of the assembly, formed of a suspension arm 12 and a fork 11, may be envisaged. In the example shown, each wheel 10 or group of wheels 10 is positioned cantilevered at the end of the suspension arm 12 to constitute indifferently a wheel pulled or pushed during the movements of the towing vehicle. This suspension arm 12 is connected, as illustrated in FIGS. 4 and 5, at one of its ends to the drive shaft 30 of a wheel or a group of wheels of the machine. while its other end is connected by a hinge 17 to the fork 11 pivoting about a vertical axis. A damper 20, such as a spring, is positioned between arm 12 and fork 11 to allow the suspension arm 12 to oscillate along the soil profile.
La commande directionnelle du véhicule s'opère à partir du poste 3 de pilotage de l'engin équipé d'un organe de commande de direction qui peut être constitué par un volant ou par un manche du type de celui équipant les avions. The directional control of the vehicle operates from the control station 3 of the machine equipped with a steering control member which can be constituted by a steering wheel or a handle of the type fitted on aircraft.
Le fait que chaque roue ou groupe de roues du châssis 2 roulant soit relié au châssis par l'intermédiaire d'un bras 12 de suspension permet d'avoir un ensemble parfaitement amorti qui accroît le confort du conducteur de l'engin. De la même manière, l'inversion de la direction de pivotement d'un train de io roues moteur à un autre permet de faciliter la manoeuvre directionnelle et de réduire le nombre de manoeuvres nécessaires, en particulier en bout de champ. Il en résulte à nouveau un confort accru du conducteur du véhicule. The fact that each wheel or group of wheels of the chassis 2 is connected to the chassis via a suspension arm 12 provides a perfectly cushioned package that increases the comfort of the driver of the machine. Likewise, the reversal of the pivoting direction of a train from one engine to another facilitates the directional maneuver and reduces the number of maneuvers required, particularly at the end of the field. This again results in increased comfort for the driver of the vehicle.
Dans les exemples représentés, la source d'énergie électrique est constituée is d'accumulateurs 16 électriques, du genre batteries, rechargeables, disposés de préférence sur le plancher du châssis 2 plateau du véhicule. Ces accumulateurs 16 électriques alimentent des variateurs 16A permettant le pilotage des moteurs 13 électriques. Les roues 10 sont quant à elles équipées de pneumatiques 21 taille basse pour accroître la surface d'appui au sol de la 20 bande de roulement, tout en autorisant une déformation de ladite bande au passage d'un obstacle lui conférant une fonction autonettoyante. In the examples shown, the source of electrical energy consists of accumulators 16 electric battery-type, rechargeable, preferably disposed on the floor of the chassis 2 vehicle tray. These 16 electric accumulators power 16A drives to control the 13 electric motors. The wheels 10 are equipped with low-profile tires 21 to increase the ground support surface of the tread, while allowing a deformation of said band when passing an obstacle giving it a self-cleaning function.
A nouveau, le positionnement sur le véhicule tracteur de roues pneumatiques avec une bande de roulement délimitant notamment une chambre creuse 25 déformable permet d'obtenir une meilleure répartition de la pression au sol exercée par la roue, la déformation de cette roue permettant d'éliminer les déchets susceptibles de s'accumuler au niveau de la surface de la bande de roulement. Again, the positioning on the towing vehicle of pneumatic wheels with a tread delimiting in particular a hollow chamber 25 deformable provides a better distribution of the ground pressure exerted by the wheel, the deformation of this wheel to eliminate waste likely to accumulate on the surface of the tread.
3o Grâce à un tel véhicule tracteur, le confort du conducteur est accru et la pollution réduite. 20 25 30 3o With such a tractor, driver comfort is increased and pollution reduced. 20 25 30
