Abstract
Description
La présente invention concerne la propulsion des véhicules en milieuThe present invention relates to the propulsion of vehicles in a medium
liquide ou simplement meuble (neige, sable et autre). liquid or simply furniture (snow, sand and other).
Pour les véhicules amphibies, la propulsion dans l'eau est obtenue soit en faisant tourner dans l'eau des roues motrices dont les pneus sont pourvus de crampons et créent un flux; soit en disposant d'un moyen séparé de propulsion par une hélice ou un hydrojet que l'on accouple au moteur lorsque le véhicule est dans l'eau. For amphibious vehicles, the propulsion in water is obtained either by turning in water driving wheels whose tires are provided with crampons and create a flow; or by having a separate means of propulsion by a propeller or a hydrojet that is coupled to the engine when the vehicle is in the water.
Dans tous les cas, on change le mode de propulsion et les rendements sont moyens voire très faibles. In all cases, we change the mode of propulsion and the yields are medium or very low.
Les bateaux sont équipés d'hélices à plusieurs pales qui peuvent devenir dangereuses pour tout baigneur. Le moindre frottement risque de casser une pale, voire l'hélice complète au contact de corps durs étrangers. Du fait de cet inconvénient, il est nécessaire d'avoir une profondeur d'eau suffisante afin d'éviter tout risque de détérioration de l'hélice, de la coque ainsi que l'échouement. The boats are equipped with propellers with several blades which can become dangerous for any bather. The least friction may break a blade, or the complete propeller in contact with foreign hard bodies. Because of this disadvantage, it is necessary to have a sufficient depth of water to avoid any risk of damage to the propeller, the hull and the grounding.
Le dispositif selon l'invention permet de remédier à ces inconvénients. Le mode de propulsion pour ce véhicule est en effet constitué d'une chenille spécifique constituée d'un train de pales: ces pales se caractérisent par leur forme de préférence parabolique qui permet d'améliorer la propulsion du liquide. la chenille peut-être guidée par un train de roue ou tout autre procédé (roulement, rails, galets, glissières). Le véhicule peut être entraîné - soit par deux chenilles de ce type situées de 30 part et d'autre, - soit par une chenille motrice à pales complétée à l'avant par une ou deux chenilles directionnelles lisses non motrices, 2876351 2 soit par une combinaison des deux chenilles latérales à pales motrices et de deux chenilles frontales favorisant la stabilité et le déjaugeage. The device according to the invention overcomes these disadvantages. The propulsion mode for this vehicle is in fact made up of a specific crawler consisting of a blade train: these blades are characterized by their parabolic shape preference which improves the propulsion of the liquid. the track can be guided by a wheel train or any other process (bearing, rails, rollers, slides). The vehicle may be driven either by two tracks of this type located on either side, or by a blade driven crawler completed at the front by one or two non-driving smooth directional crawlers, 2876351 or combination of the two lateral tracks with driving blades and two frontal tracks favoring the stability and the planing.
Les performances peuvent être améliorées en introduisant des pales dont l'angle variable sera déterminé soit par un dispositif manuel soit par asservissement à l'allure du véhicule: Globalement l'angle peut diminuer à tous les niveaux de la course lorsque la vitesse augmente afin de contribuer au déjaugeage de l'engin, réduisant ainsi la traînée dans son sillage. Performance can be improved by introducing blades whose variable angle will be determined either by a manual device or by servoing the pace of the vehicle: Overall the angle can decrease at all levels of the race when the speed increases to contribute to the planing of the craft, thus reducing drag in its wake.
En particulier, en tête de course, pour une vitesse donnée, l'angle est maximal pour brasser le plus grand volume d'eau, en milieu de course il diminue pour favoriser la poussée, en fin de course il est minimal afin d'obtenir un effet planant sur l'arrière de l'engin, assurant ainsi une portance propulsive. In particular, at the head of the race, for a given speed, the angle is maximum to brew the largest volume of water, in the middle of the race it decreases to favor the thrust, at the end of the race it is minimal in order to obtain a hovering effect on the rear of the craft, thus ensuring propulsive lift.
Lorsque la pale n'est plus immergée, elle est libérée de façon à laisser échapper le liquide qu'elle a propulsé pendant l'immersion. When the blade is no longer immersed, it is released so as to let out the liquid that it propelled during the immersion.
Enfin la chenille à pales, qu'elle soit fixe ou à angle variable, peut être combinée en un système mixte avec une ou des chenilles traditionnelles assurant la propulsion sur terre: - Ce système de chenilles peut être porté par le même mécanisme d'entraînement. Finally the caterpillar blade, whether fixed or variable angle, can be combined into a mixed system with one or more traditional crawlers providing propulsion on land: - This crawler system can be carried by the same drive mechanism .
Les deux fonctions peuvent être permanentes (pour la facilité de mise en oeuvre) ou débrayables (pour un meilleur rendement). Both functions can be permanent (for ease of implementation) or disengageable (for better performance).
Les figures annexées illustrent quelques modalités de réalisation: 2876351 3 La figure A montre une réalisation impliquant une chenille (1), utilisant dans cet exemple des pales paraboliques (2), guidée par un train de roues (3) dont l'une est motrice (4). The attached figures illustrate some embodiments: FIG. A shows an embodiment involving a track (1), using in this example parabolic blades (2), guided by a wheel train (3), one of which is driving (4).
- Les figures B et C montrent une version utilisant la pale à angle variable: chaque pale parabolique (5) est munie d'une articulation (6) autour de laquelle elle pivote et d'un doigt (7) sur lequel agit une glissière (8) elle-même pivotante sur un axe (9) en fonction de la vitesse de l'engin. Les deux illustrations B et C montrent respectivement l'état du dispositif au démarrage et en vitesse de croisière. FIGS. B and C show a version using the variable angle blade: each parabolic blade (5) is provided with a hinge (6) around which it pivots and with a finger (7) on which a slide ( 8) itself pivoting on an axis (9) depending on the speed of the machine. The two illustrations B and C respectively show the state of the device at start and cruising speed.
La figure D illustre une réalisation du système mixte: la coupe d'une roue montre une jante (10) portant la chenille à pale encadrée par deux jantes (11) portant les chenilles terrestres: un différentiel (12) distribue la puissance en favorisant la ou les jantes qui rencontrent le plus de résistance. FIG. D illustrates an embodiment of the mixed system: the section of a wheel shows a rim (10) carrying the blade track framed by two rims (11) carrying the ground tracks: a differential (12) distributes the power by promoting the or the rims that meet the most resistance.
La figure E propose à titre d'exemple un véhicule complet qui met en oeuvre deux systèmes mixtes à l'arrière (13) et deux chenilles lisses non motrices à l'avant (14). La coque porteuse et étanche (15) en matériau composite reçoit un moteur (16) de type connu. La puissance est transmise par un variateur (17) à l'arbre (18) la puissance qui est reprise par deux embrayages latéraux (19) entraînant des courroies (20) reliées à deux demi arbres (21) qui supportent le dispositif de frein (22) et la triple jante (23), détaillée en D, qui porte le système mixte de chenille. La commande de direction est obtenue en actionnant le frein (22) d'un côté tout en 15 20 25 30 2876351 4 débrayant ce même côté (19) et en transmettant la puissance sur l'autre demi arbre(21). Un moteur électrique (0) relié aux axes (9) des glissières (8) introduites dans la figure C assure le réglage de l'inclinaison des pales (5). Il est asservi à l'état du variateur (17) : quand il est ouvert, l'angle des pales est maximal, quand il se ferme, cet angle diminue. L'engin dispose ainsi d'une meilleure flottabilité et demande une puissance inférieure pour atteindre le moment critique du déjaugeage. Au-delà de ce moment, le tirant d'eau de ce véhicule à la fois amphibie et tout terrain devient très faible: sa vitesse sur eau s'approche de sa vitesse terrestre. Figure E proposes by way of example a complete vehicle that uses two mixed systems at the rear (13) and two non-driving smooth tracks at the front (14). The carrier and sealed shell (15) of composite material receives a motor (16) of known type. The power is transmitted by a variator (17) to the shaft (18) the power which is taken up by two lateral clutches (19) driving belts (20) connected to two half shafts (21) which support the brake device ( 22) and the triple rim (23), detailed in D, which carries the mixed crawler system. Steering control is achieved by operating the brake (22) on one side while disengaging the same side (19) and transmitting the power to the other half shaft (21). An electric motor (0) connected to the axes (9) of the slides (8) introduced in Figure C ensures adjustment of the inclination of the blades (5). It is slaved to the state of the variator (17): when it is open, the angle of the blades is maximum, when it closes, this angle decreases. The machine thus has better buoyancy and requires a lower power to reach the critical moment of the planing. Beyond this moment, the draft of this vehicle both amphibious and all terrain becomes very low: its speed on water approaches its speed.
Par ailleurs si l'engin ne dispose que de deux chenilles latérales, au lieu que les pales soient ouvertes en début de course pour assurer le brassage du liquide, elles y seront fermées afin de constituer la surface lisse permettant d'obtenir le déjaugeage. Furthermore, if the machine has only two side tracks, instead of the blades are opened at the start of the race to ensure the mixing of the liquid, they will be closed to form the smooth surface to obtain the planing.
