Description

DISPOSITIF DE TRANSMISSION DE PUISSANCE
VERS LE CHASSIS ARTICULE ARRIERE
D'UN TRACTEUR FORESTIER POLYVALENT
La présente invention concerne un dispositif-permettant de transmettre la puissance nécessaire a actionner par exemple un treuil et une prise de force situés sur le châssis ar rière d'un tracteur forestier ou analogue.POWER TRANSMISSION DEVICE
TOWARDS THE REAR ARTICULATED CHASSIS
OF A VERSATILE FOREST TRACTOR
The present invention relates to a device for transmitting the power necessary to actuate, for example, a winch and a PTO located on the rear chassis of a forestry tractor or the like.

Il n'existe pas actuellement de tracteur forestier possédant une prise de force sur le châssis arrière. Seuls les tracteurs agricoles sont munis d'une prise de force. Les tracteurs forestiers connus disposent seulement, soit d'un treuil mécanique pour le halage des grumes soit d'une grue destinée à charger les grumes sur un châssis porteur. There is currently no forestry tractor with a PTO on the rear chassis. Only agricultural tractors are equipped with a PTO. Known forestry tractors only have either a mechanical winch for hauling logs or a crane intended to load the logs on a carrying frame.

Le dispositif objet de la présente invention a pour but de permettre de réaliser la véritable polyvalence d'un trateur forestier ou autre engin du meme type. The object of the present invention device is to allow to achieve the true versatility of a forest trator or other machine of the same type.

A cet effet, l'invention a pour objet un dispositif de transmission de la puissance vers le châssis articulé arrière d'un tracteur forestier polyvalent, caractérisé en ce qu'il est constitué par un couplage direct d'une pompe hydraulique au convertisseur-boite du châssis avant dudit tracteur, le fluide de la pompe étant envoyé par flexible à un ou plusieurs distributeurs commandant un ou plusieurs moteurs dè treuil ou analogue et/ou une prise de force montés à l'arrière du châssis du tracteur. To this end, the subject of the invention is a device for transmitting power to the rear articulated chassis of a multipurpose forestry tractor, characterized in that it consists of a direct coupling of a hydraulic pump to the gearbox converter of the front chassis of said tractor, the pump fluid being sent by hose to one or more distributors controlling one or more winch motors or the like and / or a PTO mounted at the rear of the tractor chassis.

Suivant un mode de réalisation un tel dispositif comporte trois distributeurs dont deux commandent deux moteurs de treuils, le troisième pouvant commander sélectivement l'un ou ou l'autre desdits moteurs en vue d'augmenter la vitesse sans diminution de puissance de l'un ou l'autre treui}.  According to one embodiment, such a device comprises three distributors, two of which control two winch motors, the third being able to selectively control one or the other of said motors in order to increase the speed without decreasing the power of one or the other treui}.

vantageusement, les retours des trois distributeurs sont reliés à un distributeur à pilotage manuel alimentant un moteur de prise de force. advantageously, the returns from the three distributors are connected to a manual piloted distributor supplying a PTO motor.

D'autres caractéristiques et avantages ressortiront de la description qui va suivre donnée à titre d'exemple uniquement et en regard du dessin annexé sur lequel la figure unique illustre schématiquement un mode de réalisation du dispositif selon l'invention. Other characteristics and advantages will emerge from the description which follows, given by way of example only and with reference to the appended drawing in which the single figure schematically illustrates an embodiment of the device according to the invention.

Le dispositif de transmission de puissance de l'invention comporte un ensemble convertisseur-bolte de vitesse 1 recevant sa puissance du moteur a combustion interne d'un tracteur forestier à châssis articulé par un arbre 2. Cet ensemble transmet sa puissance, dXune part, auxrroues motrices du tracteur et, d'autre part, a une prise de mouse- ment 3. The power transmission device of the invention comprises a converter-gearbox assembly 1 receiving its power from the internal combustion engine of a forestry tractor with articulated frame by a shaft 2. This assembly transmits its power, on the one hand, to the wheels tractor drive units and, on the other hand, has a mouse socket 3.

Il est de pratique courante de transmettre le mouvement vers la partie arrière 4 du châssis articule par l'inter médiaire d'un cardan situé au niveau de l'articulation des parties arrière 4 et avant 5 du châssis. It is common practice to transmit the movement to the rear part 4 of the articulated chassis by means of a cardan joint located at the articulation of the rear 4 and front 5 parts of the chassis.

Mais un cardan ne permet pas de transmettre des couples élevés à grande vitesse (approximativement 3.000 t/mn) et pour des angles importants entre les parties avant et arrière dü tracteur articulé. However, a universal joint does not allow high torques to be transmitted at high speed (approximately 3,000 rpm) and for large angles between the front and rear parts of the articulated tractor.

La faiblesse du couple transmis interdit l'utilisation de la prise de force vers la partie arrière b pour actionner de gros treuils et une prise de force dont la puissance se rapproche au plus près de la puissance du moteur à combustion interne du tracteur. The weakness of the transmitted torque prevents the use of the power take-off towards the rear part b for operating large winches and a power take-off whose power comes as close as possible to the power of the tractor's internal combustion engine.

Ce résultat est obtenu dans la présente invention en actionnant directement une pompe hydraulique 6 à l'aide d'un joint élastique 7 fixé directement sur la bride 8 de l'arbre de prise de mouvement 3 du convertisseur-boite 1. This result is obtained in the present invention by directly actuating a hydraulic pump 6 using an elastic seal 7 fixed directly on the flange 8 of the power take-off shaft 3 of the converter-box 1.

La pompe 6 reçoit l'huile par l'aspiration 9 et renvoie cette huile par trois tuyaux flexibles séparés 10,11, 12 alimentant trois distributeurs 13, 14, 15. Les tuyaux flexibles 10, 11, 12 sont situés au niveau de l'articulation (symbolisée par l'axe A) du châssis avant 5 et du châssis arrière 4. The pump 6 receives the oil by the suction 9 and returns this oil by three separate flexible pipes 10, 11, 12 supplying three distributors 13, 14, 15. The flexible pipes 10, 11, 12 are situated at the level of the articulation (symbolized by axis A) of the front chassis 5 and the rear chassis 4.

Cette disposition permet, contrairement au cardan, -de transmettre au châssis arrière 4 des puissances importantes avec des pertes minimes de rendement même pour des angles importants entre châssis avant 5 et arrière 4. En outre, l'endurance des tuyaux flexibles 10, 11, 12 est très supérieure à celle d'un cardan et ces tuyaux sont d'un prix moins élevé.This arrangement makes it possible, unlike the gimbal, to transmit to the rear chassis 4 significant powers with minimal losses of performance even for large angles between the front chassis 5 and rear 4. Furthermore, the endurance of the flexible pipes 10, 11, 12 is much higher than that of a universal joint and these pipes are cheaper.

Le distributeur 13 envoie l'huile au moteur 16 d'un pre mier treuil 17. Le distributeur 15 envoie l'huile au moteur 18 d'un second treuil 19. Le distributeur 14 est disponible et peut envoyer son débit vers le moteur 16 ou le moteur 18 afin d'augmenter la vitesse des treuils tout en conservant la même puissance. The distributor 13 sends the oil to the motor 16 of a first winch 17. The distributor 15 sends the oil to the motor 18 of a second winch 19. The distributor 14 is available and can send its flow rate to the motor 16 or the motor 18 in order to increase the speed of the winches while retaining the same power.

Les distributeurs 13, 14, 15 sont commandés par un circuit hydraulique de pilotage distribué par des électrovannes non représentées sur le dessin. Ces électrovannes sont commandées depuis le tableau de bord du tracteur par un circuit électrique. The distributors 13, 14, 15 are controlled by a hydraulic control circuit distributed by solenoid valves not shown in the drawing. These solenoid valves are controlled from the tractor dashboard by an electrical circuit.

Les retours distributeurs 13, 14, 15 sont reliés par la conduite 20 à un distributeur a pilotage manuel 21 alimentant un moteur de prise de force 22. Lorsque la prise de force ne fonctionne pas le débit est renvoyé directement au réservoir 23 par le pilotage manuel. The distributor returns 13, 14, 15 are connected by line 20 to a manual piloted distributor 21 supplying a PTO motor 22. When the PTO does not work, the flow rate is returned directly to the reservoir 23 by manual piloting. .

Bien entendu, l'invention n'est pas limitée au mode de réalisation représenté et décrit ci-dessus mais en couvre au contraire toutes les variantes.  Of course, the invention is not limited to the embodiment shown and described above, but on the contrary covers all variants.
