Abstract

Dual-acting nautical suspension characterised in that it includes at least two elements in series, one (13) articulated on its front (bow) at (37) absorbs, via its significant angular variations, the greater part of the variations in surface, the second (13') articulated on the back of (13) (at 37') optimises the best contact with the moving fluid by adjusting its incidence ( alpha ) to keep this constant regardless of that of the main supporting plane (13), this being by virtue of a set of dampers (4), (5) or (20) which, by slaving to the upthrust by means of a pressure sensor (6) allows this operation, which is of supporting the moving hull (14) using one or more suspension assemblies.

Description

La présente invention est un perfectionnement apporté à une suspension à double effet , composé de deux volets articulés ou deux éléments en série assurant la portance ou sustentation de l'engin nautique considéré,controlé en nouvement par système d'amortisseur hydraulique, pneumatique, hydropneumatique , concu de façon à ce durcir automatiquement fonction de la vitesse ou de la dureté du plan d'eau.L'engin nautique considéré est suspendu généralement sur plusieurs points,équipé de la dite invention La présente invention consiste en un système qui permet de controler un appuis indépendament de l'autre grace à un séparateur constitué de deux chambres élastiques étanches l'une par rapport à l'autre ,réalisé sous la forme de deux soufflets transmettant la force de la pression ou la poussée, par empilement d'un soufflet à l'autre grace à leur flasques extrèmes , qui aux extrèmités opposées sont solidaires d'un chassis ou point fixe.L'un des soufflet est alimenté en pression d'eau par une prise de pression totale ou règlable en contact avec le fluide porteur.The present invention is an improvement made to a double-acting suspension, composed of two articulated flaps or two elements in series ensuring the lift or lift of the nautical craft in question, newly controlled by a hydraulic, pneumatic, hydropneumatic damper system, designed so as to harden automatically depending on the speed or the hardness of the water body. The considered nautical machine is generally suspended on several points, equipped with the said invention The present invention consists of a system which makes it possible to control a support independently of the other thanks to a separator made up of two elastic chambers which are sealed with respect to each other, produced in the form of two bellows transmitting the force of the pressure or the thrust, by stacking a bellows at the other thanks to their extreme flanges, which at opposite ends are secured to a frame or fixed point. One of the bellows is supplied with water pressure by a total or adjustable pressure tap in contact with the carrier fluid.

La pression interne va donc augmenter automatiquement fonction de la vitesse et transformée en pression d'airéquiva- lente dans le soufflet opposé,par réaction des appuis sur le chassis qui autorisent la transmission intégale d'un soufflet d l'autre .On pressurise le soufflet d'air grace à une valve située sur le circuit d'air de façon à prétarrer la suspension fonction de la charge. Une prise de pression totale peut commander plusieurs appuis suspendus ainsi équipés.Grace à un jeu de vanne à règlage micromètrique ou restriction équivalentes monté sur l'alimentation des soufflet (eau),on règle l'assiette axiale ou longitudinale de la coque ainsi équipée.The internal pressure will therefore automatically increase depending on the speed and transformed into equivalent air pressure in the opposite bellows, by reaction of the supports on the chassis which allow the integral transmission of one bellows from the other. air thanks to a valve located on the air circuit so as to pre-adjust the suspension according to the load. A total pressure tap can control several suspended supports thus equipped. Thanks to a set of micrometric adjustment valve or equivalent restriction mounted on the bellows supply (water), the axial or longitudinal attitude of the hull thus equipped is adjusted.

Un système purement hydraulique ou Flectrique ou en partie convient pourvu qu ' il respecte le fonctionnement initiale de la suspension à double effet.A purely hydraulic or electric system or in part suitable as long as it respects the initial functioning of the double-acting suspension.

La figure 1 représente un convertisseur ou séparateur eau/air
à deux soufflets
La figure 2 représente un exemple de montage du circuit de
controle de la suspension à double effet.
Figure 1 shows a water / air converter or separator
with two bellows
Figure 2 shows an example of mounting the circuit
double-acting suspension control.

Selon la figure 1 le séparateur (22) est constitué d'un chassis réalisé sous la forme de deux flasques ou deux plaques (45) situées aux extrèmités de tiges, colonnes, prévues à cet effet , qui contiennent la poussée des soufflets (1) et (2) en sériexempilés. Ces soufflets du commerce sont réalisés en matèriaux élastiques étanches, sous la forme de plusieurs anneaux circulaires renforcés par des bagues, ajusté PU diamètre minimum, évitant toute distension des membranes ou paroies des soufflets (1) et (2)et garantissant une transmission intégrale de la pression en eau de (1) en air de (2).Ces bagues(16) sont en matèriaux plastique ou métalique prévu à cet effet.Des flasques (8) contrôle le maintient et l'étanchéité des soufflets (1) et (2) sur lesflasques (45) grace au sérrage des écrous et tiges filetés (15t sur les plaques(45).According to Figure 1 the separator (22) consists of a frame made in the form of two flanges or two plates (45) located at the ends of rods, columns, provided for this purpose, which contain the thrust of the bellows (1) and (2) in stacked series. These commercial bellows are made of waterproof elastic materials, in the form of several circular rings reinforced with rings, adjusted PU minimum diameter, avoiding any distension of the membranes or walls of the bellows (1) and (2) and guaranteeing an integral transmission of water pressure from (1) to air from (2). These rings (16) are made of plastic or metallic materials provided for this purpose. Flanges (8) control the maintenance and tightness of the bellows (1) and ( 2) on the flanges (45) thanks to the tightening of the nuts and threaded rods (15t on the plates (45).

Les écrous (44) assurent la rigidité de l'ensmble tige ou colonne (3) et plaques (45).Une plaque (7') de diamètre suffisant assure la liaison mécanique d'étanchéité entre les deux soufflets (1) et (2) par empilement et serrage des deux anneaux (7) percés et maintenus par des tiges filetés et écrous (in), cette bride flottante ce déplace au grès des variations de pression . Des raccords (9) assurent la liaison d'une part avec le circuit d'air et d'autre part avec le circuit d'eau, vissé respectivement dans leur flasque(45).The nuts (44) ensure the rigidity of the whole rod or column (3) and plates (45). A plate (7 ') of sufficient diameter ensures the mechanical sealing connection between the two bellows (1) and (2 ) by stacking and tightening the two rings (7) drilled and held by threaded rods and nuts (in), this floating flange moves sandstone pressure variations. Connections (9) provide the connection on the one hand with the air circuit and on the other hand with the water circuit, screwed respectively into their flange (45).

Selon la figure 2 les séparateurs (22) assurant le fonction nement de trois points suspendus à double effet constitués chacun d'un volet (13) et (13') en série pneumatiquement controlé par des soufflets(4) et (5) et amortis si besoin par des vérins (20).Un séparateur (22) alimenté en air par une valve (50) est prétarré fonction de la charge indépendament d'un appuis par rapport à un autre pour un réglage de l'assiette initiale.Une vanne (41) situé sur le circuit de pressurisation d'eau, alimenté par prise de pression totale (6), permet le réglage d'assiette longitudinale dynamique en règlant la pression entre les circuits des suspensions (A) et avant (B).Ce fonctionnement est possible grace à un débit de fuite règlé par des restrictions ou échapements règlable à l'atmosphère(42), (40'),(52) .Ces restrictions
échappements règlable(40') permettent de règler l'assiette latérale entre les suspensions(A) et (A') et ceci fonction de l'angle de virage de la direction (15),ceci augmente la manoeuvrabilité de l'engin en l'inclinant.Quand l'une des restrictions(40') s'ouvre l'autre se ferme simultanément controlé par des biellettes couplées à la direction (15).
According to Figure 2 the separators (22) ensuring the operation of three double-acting hanging points each consisting of a flap (13) and (13 ') in series pneumatically controlled by bellows (4) and (5) and damped if necessary by jacks (20). A separator (22) supplied with air by a valve (50) is pre-set depending on the load independently of one support relative to another for an adjustment of the initial attitude. (41) located on the water pressurization circuit, supplied by total pressure tap (6), allows the adjustment of dynamic longitudinal attitude by adjusting the pressure between the suspension circuits (A) and front (B). operation is possible thanks to a leak rate regulated by restrictions or exhausts adjustable to the atmosphere (42), (40 '), (52).
adjustable exhausts (40 ') make it possible to adjust the lateral attitude between the suspensions (A) and (A') and this depends on the turning angle of the steering (15), this increases the maneuverability of the machine in l When one of the restrictions (40 ') opens the other closes simultaneously controlled by rods coupled to the direction (15).

Dans le cas de fonctionnemnet hydraulique motorisé les commandes sont de type classique adapté à cet autre mode de fonctionnement qui est aussi électrique pour certaine variantes pourvu que l'on respecte le fonctionnement initial.In the case of motorized hydraulic operation, the controls are of the conventional type adapted to this other operating mode which is also electric for certain variants provided that the initial operation is respected.

Il < i doit etre entendu que la description qui précède n'à été donné qu'à titre d'exemple et qu'elfene limite nullement le domaine d'application dont on ne sortirait pas en rempla canut des détails d'execution décrits par tous autre équivalents de suspension àdurcissement hydrodynamique. It should be understood that the foregoing description has been given by way of example only and that elfene in no way limits the field of application from which one would not depart in lieu of execution details described by all other hydrodynamically hardened suspension equivalents.

Un séparateur réalisé sous la forme d'une cavité séparée en deux par une membrane convient particulièrement à un mode réalisation de l'invention. A separator produced in the form of a cavity separated in two by a membrane is particularly suitable for an embodiment of the invention.
