Description

EQUIPEMENT DE TRACTION PAR CABLE ET VEHICULE ASSOCIE  CABLE TRACTION EQUIPMENT AND VEHICLE
La présente invention concerne le domaine des véhicules d'entretien des pistes skiables et plus particulièrement les véhicules équipés d'un treuil permettant une compensation du couple de traction grâce à l'utilisation d'un câble. The present invention relates to the field of maintenance vehicles of ski slopes and more particularly vehicles equipped with a winch for compensation of the traction torque through the use of a cable.
Ce type de véhicules est déjà largement utilisé à travers le monde et permet d'augmenter de manière significative le champ d'action des véhicules d'entretien en permettant l'accès à des zones plus pentues et/ou dans lesquelles le manteau neigeux n'est pas très stable.  This type of vehicle is already widely used throughout the world and can significantly increase the scope of maintenance vehicles by allowing access to steeper areas and / or in which the snowpack does n ' is not very stable.
Néanmoins, les véhicules d'entretien à treuil de l'état de la technique présentent aussi des inconvénients. Nevertheless, the winch maintenance vehicles of the state of the art also have drawbacks.
En effet, le poids de ces véhicules étant de plusieurs tonnes, la résistance du câble doit être en conséquence. Les câbles utilisés étant des câbles en acier d'une longueur allant de 850 à 1200m, le poids du câble seul est de 700 à 900kg et peut représenter jusqu'à 10% du poids du véhicule.  Indeed, the weight of these vehicles being several tons, the resistance of the cable must be accordingly. The cables used being steel cables with a length of 850 to 1200m, the weight of the cable alone is 700 to 900kg and can represent up to 10% of the weight of the vehicle.
Ainsi, l'ensemble composé du treuil et du câble représente une masse conséquente pouvant provoquer un déséquilibre du véhicule et nécessitant une puissance accrue du véhicule impliquant une augmentation de la consommation.  Thus, the assembly of the winch and the cable is a substantial mass that can cause an imbalance of the vehicle and requiring increased power of the vehicle involving an increase in consumption.
Afin, d'éviter tout déséquilibre, les treuils 3 des véhicules 1 de l'état de la technique tels que représenté sur la figure 1 sont positionnés à l'arrière et le plus bas possible. Néanmoins, un tel positionnement implique l'utilisation d'un système de poulies 5 afin d'orienter le câble métallique 7 de l'avant du véhicule vers le tambour d'enroulement du treuil 3 et un guide- câble afin de positionner correctement le câble métallique 7 sur le tambour et d'éviter toute torsion du câble métallique 7 qui pourrait l'endommager.  In order to avoid any imbalance, the winches 3 of the vehicles 1 of the state of the art as shown in FIG. 1 are positioned at the rear and as low as possible. Nevertheless, such positioning involves the use of a pulley system 5 to guide the wire rope 7 from the front of the vehicle to the winding drum of the winch 3 and a cable guide to correctly position the cable 7 on the drum and avoid any twisting of the wire rope 7 which could damage it.
D'autre part, l'ensemble du bras de support 8 comprenant les poulies 5 et le treuil doit être articulé de manière rotative par rapport au châssis du véhicule, ce qui nécessite des équipements coûteux (roulements surdimensionnés...) du fait du poids de l'ensemble et donc des coûts de production élevés. De plus, les câbles acier ne sont pas réparables sur site et leur remplacement en cas d'endommagement est très coûteux. On the other hand, the assembly of the support arm 8 comprising the pulleys 5 and the winch must be rotatably articulated relative to the chassis of the vehicle, which requires expensive equipment (oversized bearings ...) due to the weight of all and therefore high production costs. In addition, the steel cables are not repairable on site and their replacement in case of damage is very expensive.
Par ailleurs, ces câbles en acier peuvent être dangereux pour les opérateurs lors de leur maniement mais aussi pour les personnes situées à proximité en cas de rupture du câble sous tension en raison de l'effet coup de fouet.  In addition, these steel cables can be dangerous for operators when handling them but also for people in the vicinity in case of breakage of the live cable due to the whiplash effect.
Le but de la présente invention est donc de surmonter, au moins partiellement, les inconvénients précités de l'état de la technique et de proposer un équipement de traction permettant de réduire le poids et donc la consommation du véhicule, de simplifier le mécanisme d'orientation du câble lié au treuil et d'améliorer la sécurité des personnes manipulant le câble ou situées à proximité du câble. The object of the present invention is therefore to overcome, at least partially, the aforementioned drawbacks of the state of the art and to propose traction equipment making it possible to reduce the weight and therefore the consumption of the vehicle, to simplify the mechanism of orientation of the rope attached to the winch and improve the safety of people handling the cable or located near the cable.

Dans la description qui va suivre, on désigne de façon générale: In the description which follows, generally denotes:
Le terme «piste skiable» correspond à toute piste enneigée de manière naturelle ou artificielle destinée à recevoir des utilisateurs de skis ou tout autre moyen permettant de se déplacer sur la neige. The term "ski run" refers to any natural or artificial snow-covered piste intended for ski users or any other means of moving on snow.
Les modes de réalisation de la présente invention concernent l'équipement de traction par câble d'un véhicule d'entretien de piste skiable. Embodiments of the present invention relate to cable pulling equipment of a ski run maintenance vehicle.
Cet équipement comprend un câble en matière synthétique ainsi qu'une structure comportant un treuil destiné à accueillir le câble, cette structure étant installée sur le véhicule.  This equipment comprises a cable of synthetic material and a structure comprising a winch for receiving the cable, this structure being installed on the vehicle.
Un câble synthétique étant moins lourd qu'un câble métallique, en acier par exemple, cela réduit les contraintes liées au treuil et notamment son positionnement sur le véhicule et les effets de ce positionnement sur l'équilibre du véhicule. Ainsi, selon un mode de réalisation de la présente invention, le treuil 9 est positionné sur un bâti 11 juste derrière la cabine 13 et à une hauteur supérieure à la cabine 13 et à d'éventuels équipements rattachés à la cabine comme un gyrophare 14 ou un système d'éclairage (non représenté) tel que représenté sur la figure 2.  A synthetic cable being lighter than a steel cable, for example, this reduces the constraints related to the winch and in particular its positioning on the vehicle and the effects of this positioning on the balance of the vehicle. Thus, according to one embodiment of the present invention, the winch 9 is positioned on a frame 11 just behind the cabin 13 and at a height greater than the cabin 13 and any equipment attached to the cabin as a beacon 14 or a lighting system (not shown) as shown in Figure 2.
Ce positionnement permet de libérer la vision depuis la cabine 13 vers l'arrière du véhicule 1 ce qui permet de faciliter et d'améliorer le travail du pilote du véhicule 1.  This positioning allows to release the vision from the cabin 13 to the rear of the vehicle 1 which facilitates and improves the work of the driver of the vehicle 1.
De plus, le tambour 17 du treuil 9 est positionné sur le bâti 11 de manière à ce que son axe de rotation 21 soit vertical lorsque le véhicule est sur un plan horizontal. En effet, la position haute du treuil 9 et l'orientation du tambour 17 permet au câble synthétique 15 de s'enrouler directement sur le tambour 17 du treuil 9 sans passer par un système complexe de poulies. Un système simple de poulies peut néanmoins être utilisé en bout de potence afin d'abaisser le point d'application de l'effort de traction du câble 15 sur le véhicule 1. In addition, the drum 17 of the winch 9 is positioned on the frame 11 so that its axis of rotation 21 is vertical when the vehicle is on a horizontal plane. Indeed, the high position of the winch 9 and the orientation of the drum 17 allows the synthetic cable 15 to wind directly on the drum 17 of the winch 9 without going through a complex system of pulleys. A simple system of pulleys can nevertheless be used at the end of the stem to lower the point of application of the tensile force of the cable 15 to the vehicle 1.
D'autre part, la souplesse du câble synthétique 15 supprime les problèmes de torsion pouvant intervenir sur les câbles métalliques 7 et permet d'enrouler le câble directement sur le tambour 17 sans utiliser de système de guidage aussi appelé guide-câble. En effet, lors de l'enroulement du câble (aussi appelé trancanage), le câble synthétique 15 n'a pas d'effet ressort en cas de glissement du câble 15 contrairement aux câbles métalliques.  On the other hand, the flexibility of the synthetic cable 15 eliminates the torsion problems that can occur on the metal cables 7 and allows to wind the cable directly on the drum 17 without using a guide system also called cable guide. Indeed, during the winding of the cable (also called trancanage), the synthetic cable 15 has no spring effect in case of slipping of the cable 15 unlike the metal cables.
Le câble synthétique 15 est donc guidé par une simple potence 19 dont l'axe de rotation 21 est confondu avec l'axe de rotation du tambour 17. La potence 19 tourne librement autour de son axe de rotation 21 en fonction de l'orientation du câble 15, néanmoins, un moteur dédié (non représenté) peut également être couplé à la potence 19 afin de permettre au conducteur du véhicule 1 d'orienter la potence 19 lorsque cela est nécessaire. Ainsi seule la potence est fixée de manière rotative sur le bâti. La potence ayant un poids réduit par rapport au bâti, cette conception permet de simplifier la structure et de réduire les coûts de production par rapport aux modèles de l'état de la technique.  The synthetic cable 15 is thus guided by a simple bracket 19 whose axis of rotation 21 coincides with the axis of rotation of the drum 17. The bracket 19 rotates freely about its axis of rotation 21 depending on the orientation of the cable 15, however, a dedicated motor (not shown) can also be coupled to the bracket 19 to allow the driver of the vehicle 1 to direct the bracket 19 when necessary. Thus only the bracket is rotatably attached to the frame. The stem has a reduced weight compared to the frame, this design simplifies the structure and reduce production costs compared to the models of the state of the art.
La position avancée du treuil 9 par rapport au véhicule 1 permet également d'améliorer l'équilibre du véhicule 1, notamment lorsque l'angle a fait par l'axe du câble 23 et l'axe du véhicule 25 augmente comme représenté sur la figure 3. Dans le premier cas (a) où le treuil 9 est positionné à l'arrière du véhicule 1, l'effort de traction du câble 15 tend à déséquilibrer le véhicule 1 tandis que dans le deuxième cas (b), la position du treuil 9 vers l'avant du véhicule 1, l'effort de traction du câble 15 continue à entraîner le véhicule 1 sans le déséquilibrer.  The advanced position of the winch 9 relative to the vehicle 1 also improves the balance of the vehicle 1, especially when the angle made by the axis of the cable 23 and the vehicle axis 25 increases as shown in FIG. 3. In the first case (a) where the winch 9 is positioned at the rear of the vehicle 1, the tensile force of the cable 15 tends to unbalance the vehicle 1 while in the second case (b), the position of the winch 9 towards the front of the vehicle 1, the tensile force of the cable 15 continues to drive the vehicle 1 without unbalancing it.
D'autre part, le tambour 17 du treuil 9 est entraîné en rotation par un moteur hydraulique 27 situé en dessous du tambour 17 et fixé au bâti 11. Afin d'assurer l'accouplement du moteur et du tambour, le moteur peut être soit directement flasqué sur le tambour soit accouplé au tambour par l'intermédiaire d'un système d'entraînement comprenant un ou plusieurs engrenages, une chaîne ou un cardan. On the other hand, the drum 17 of the winch 9 is rotated by a hydraulic motor 27 located below the drum 17 and fixed to the frame 11. In order to ensure the coupling of the motor and the drum, the motor can be either directly flanged on the drum is coupled to the drum via a drive system comprising one or more gears, a chain or a gimbal.
Dans la pratique, le câble 15 est relié à un ancrage 29 situé en haut de la piste ou portion de piste à entretenir tel que représenté sur la figure 4. La liaison entre le câble synthétique 15 et l'ancrage 29 se faisant par exemple par un crochet attaché à l'extrémité du câble synthétique 15. In practice, the cable 15 is connected to an anchor 29 located at the top of the track or track portion to be maintained as shown in FIG. 4. The connection between the synthetic cable 15 and the anchoring 29 being made for example by a hook attached to the end of the synthetic cable 15.
Lors de l'ascension de la piste, le véhicule 1 se déplace par l'action combinée des chenilles 31 et du treuil 9. Ces moyens de traction doivent permettre de faire monter l'ensemble constitué du véhicule 1 ainsi qu'une éventuelle quantité de neige 33. Le dimensionnement des différents éléments doit donc prendre en compte le poids total de l'ensemble véhicule+neige.  During the ascent of the track, the vehicle 1 moves by the combined action of the tracks 31 and the winch 9. These traction means must allow to raise the assembly of the vehicle 1 and a possible amount of snow 33. The sizing of the various elements must therefore take into account the total weight of the vehicle + snow package.
Les modes de réalisation de la présente invention permettent donc de réduire le poids du câble 15, du treuil 9 et en conséquence du bâti supportant le treuil et le câble, ce qui permet soit de réduire le poids total à tracter et donc l'énergie nécessaire à la traction du véhicule, soit d'augmenter la quantité de neige pouvant être poussée et donc de réduire le nombre de passages et par conséquence le temps et l'énergie nécessaire. The embodiments of the present invention therefore make it possible to reduce the weight of the cable 15, of the winch 9 and consequently of the frame supporting the winch and the cable, which makes it possible either to reduce the total weight to be towed and therefore the necessary energy. when pulling the vehicle, to increase the amount of snow that can be pushed and thus reduce the number of passages and consequently the time and energy required.
Par ailleurs, comme représenté sur la figure 3, la traction du câble ne se fait pas toujours dans l'axe du véhicule de sorte que la vitesse d'enroulement et/ou de déroulement du treuil 9 doit être asservie pour rester coordonnée avec la vitesse des chenilles 31 et afin de maintenir une tension constante au niveau du câble synthétique 15.  Furthermore, as shown in Figure 3, the traction of the cable is not always in the axis of the vehicle so that the speed of winding and / or unwinding of the winch 9 must be controlled to remain coordinated with the speed tracks 31 and to maintain a constant tension at the synthetic rope 15.
De plus, du fait de l'absence d'effet ressort du câble 15, il n'est pas nécessaire, lors des phases de descente, de maintenir une forte tension au câble 15 par l'intermédiaire du moteur d'enroulement 27 puisqu'il n'y a pas de risque pour le câble 15 de s'emmêler si la tension diminue (par exemple à cause d'une bosse ou d'un replat sur la piste), ce qui permet de réduire la consommation du moteur d'enroulement 27 lors de la phase de déroulement du câble 15. Les modes de réalisation de la présente invention visent également à améliorer la sécurité vis- à -vis de l'utilisation de treuil 9 à câble.  In addition, due to the absence of a spring effect of the cable 15, it is not necessary, during the descent phases, to maintain a high tension to the cable 15 via the winding motor 27 since there is no risk for the cable 15 to become entangled if the voltage decreases (for example because of a bump or a flattening on the track), which makes it possible to reduce the engine consumption of during the unwinding phase of the cable 15. The embodiments of the present invention also aim to improve the safety vis-à-vis the use of cable winch 9.
L'utilisation d'un câble synthétique 15 permet de supprimer le risque de blessures liées au maniement du câble par l'opérateur. En effet, contrairement à un câble métallique 7, le câble synthétique 15 ne produit pas d'effîlochures ou d'échardes et préserve les mains de l'opérateur même lors d'une manipulation à mains nues.  The use of a synthetic cable 15 eliminates the risk of injury related to the handling of the cable by the operator. Indeed, unlike a wire rope 7, the synthetic cable 15 does not produce efflichures or splinters and preserves the hands of the operator even when handling with bare hands.
Le faible poids permet également une manipulation plus aisée pour l'opérateur, notamment lors de la phase d'accrochage du câble 15 à l'ancrage 29.  The low weight also allows easier handling for the operator, especially during the hooking phase of the cable 15 to the anchor 29.
De plus, le câble peut présenter un danger vis à vis des personnes se trouvant à proximité du câble comme des randonneurs et des personnels d'exploitation se déplaçant à pied, en motoneige ou à ski. L'entretien des pistes se faisant essentiellement de nuit un câble métallique 7 est difficilement perceptible et pourrait provoquer un accident en cas de choc. Ainsi, selon un mode de réalisation de la présente invention, le câble synthétique est photoluminescent ou possède un effet réfléchissant de manière à être clairement perceptible la nuit. Cette photo-luminescence et cet effet réfléchissant peuvent être apportés par la structure du câble en utilisant un matériau photo-luminescent ou réfléchissant lors de sa fabrication ou par l'ajout d'une enveloppe photo-luminescente ou réfléchissante autour du câble. Par ailleurs, un câble comprenant des parties réfléchissantes et des parties photo-luminescentes peut aussi être utilisé de manière à combiner les avantages et offrir une bonne perception du câble en toutes conditions. In addition, the cable may present a danger to people in the vicinity of the cable such as hikers and operating personnel traveling on foot, snowmobile or ski. The maintenance of the tracks being essentially at night a cable metal 7 is hardly noticeable and could cause an accident in case of shock. Thus, according to one embodiment of the present invention, the synthetic cable is photoluminescent or has a reflecting effect so as to be clearly perceptible at night. This photoluminescence and this reflective effect can be provided by the structure of the cable by using a photo-luminescent or reflective material during its manufacture or by the addition of a photoluminescent or reflective envelope around the cable. In addition, a cable comprising reflective portions and light-emitting portions can also be used to combine the advantages and provide a good perception of the cable in all conditions.
Par ailleurs, le danger réside aussi dans le risque, pour les personnes à proximité du câble, en cas de rupture du câble. Or, dans le cas d'un câble synthétique 15, il n' y a pas d'effet « coup de fouet » lors de la rupture du câble en charge et donc pas de danger pour les personnes présentes dans l'environnement du câble. Moreover, the danger also lies in the risk for people near the cable, in case of breakage of the cable. However, in the case of a synthetic cable 15, there is no effect "whiplash" when breaking the load cable and therefore no danger to people in the environment of the cable.
De plus, en cas de rupture, le câble synthétique 15 peut, contrairement à un câble métallique 7, se réparer sur site ce qui réduit les coûts d'entretien et les coûts d'exploitation puisqu'une fois la réparation faite (par exemple par épissure) sur site, le véhicule peut reprendre son travail sans avoir besoin de retourner à la station.  In addition, in case of breakage, the synthetic cable 15 may, unlike a wire rope 7, repair itself on site which reduces maintenance costs and operating costs since once the repair is done (for example by splicing) on site, the vehicle can return to work without the need to return to the station.
Par ailleurs, il est à noter que pour obtenir un fonctionnement optimal, il ne suffit pas d'installer le bâti 11 de la présente invention sur le châssis d'un véhicule d'entretien de piste de l'état de la technique mais que le châssis lui-même doit être adapté de manière à prendre en compte les contraintes liées à la géométrie de l'équipement de traction par treuil décrit précédemment.  Furthermore, it should be noted that in order to obtain optimal operation, it is not sufficient to install the frame 11 of the present invention on the chassis of a state-of-the-art track maintenance vehicle but that the The chassis itself must be adapted to take into account the constraints related to the geometry of the winch traction equipment previously described.
Ainsi, la présente invention permet, grâce à l'utilisation d'un câble synthétique 15 et à la conception d'une nouvelle configuration du véhicule tracté 1 et en particulier d'une disposition adéquate du tambour 17 du treuil 9, d'offrir un équipement de traction par câble plus simple et plus léger permettant ainsi de réduire les coûts de production et la consommation énergétique. De plus, l'utilisation d'un câble synthétique 15 permet de faciliter le travail de l'opérateur et d'améliorer la sécurité des personnes. Thus, the present invention makes it possible, thanks to the use of a synthetic cable 15 and to the design of a new configuration of the towed vehicle 1 and in particular to a suitable disposition of the drum 17 of the winch 9, to offer a simpler and lighter cable pulling equipment thus reducing production costs and energy consumption. In addition, the use of a synthetic cable 15 facilitates the work of the operator and improve the safety of people.
