Description
DISPOSITIF D'ASPIRATION POUR VEHICULES DE VOIRIE ARTICULESSUCTION DEVICE FOR ARTICULATED ROAD VEHICLES
La présente invention concerne un dispositif d'aspiration prévu pour être utilisé sur des véhicules de voirie articulés, tels que par exemple, des The present invention relates to a suction device intended to be used on articulated road vehicles, such as, for example,
balayeuses urbaines.urban sweepers.
Les véhicules de ce type se composent, pour l'essentiel, d'un châssis articulé, comportant au moins deux essieux et auquel peuvent être reliés les moyens de nettoyage tels que des brosses ou balais, des moyens d'aspiration, un réceptacle pour recevoir les résidus aspirés, éventuellement un réservoir d'eau de capacité suffisante et un poste de commande. Le châssis est en fait composé de deux demi-châssis, la partie avant recevant les moyens d'aspiration et la partie arrière recevant la cuve et les Vehicles of this type essentially consist of an articulated chassis, comprising at least two axles and to which the cleaning means such as brushes or brushes can be connected, suction means, a receptacle for receiving residues sucked in, possibly a water tank of sufficient capacity and a control station. The chassis is in fact composed of two half-chassis, the front part receiving the suction means and the rear part receiving the tank and the
éléments de motorisation.motorization elements.
Les moyens d'aspiration comportent une turbine d'aspiration et des moyens pour la collecte et le transfert des déchets aspirés jusqu'au réceptacle, Ces moyens d'aspiration sont le plus souvent constitués d'un ou de The suction means comprise a suction turbine and means for collecting and transferring the aspirated waste to the receptacle. These suction means most often consist of one or more
plusieurs tuyaux reliés à des buses d'aspiration. several pipes connected to suction nozzles.
Pour aspirer les déchets, on créé une dépression à l'intérieur du réceptacle. Les déchets sont en général humidifiés juste avant aspiration, pour faciliter leur transfert jusqu'au fond de la cuve. Ceci permet de les lier et d'éviter un To vacuum the waste, a vacuum is created inside the receptacle. The waste is generally humidified just before suction, to facilitate its transfer to the bottom of the tank. This makes it possible to link them and avoid a
rejet des poussières au travers de la turbine. rejection of dust through the turbine.
Ces modalités sont sources de nombreux problèmes, qui obèrent ou These methods are the source of many problems, which obstruct or
limitent la fiabilité des opérations d'aspiration. limit the reliability of suction operations.
En effet, la partie inférieure du conduit d'aspiration est reliée au châssis Indeed, the lower part of the suction duct is connected to the chassis

avant du véhicule par sa buse, qui est disposée de manière a recueillir les déchets collectés sur l'avant ou sur les côtés par les balais ou brosses. Par front of the vehicle by its nozzle, which is arranged so as to collect the waste collected on the front or on the sides by the brooms or brushes. Through
contre, la cuve réceptrice est montée sur la partie arrière du châssis. on the other hand, the receiving tank is mounted on the rear part of the chassis.
Le tuyau d'aspiration est donc soumis aux diverses contraintes qui The suction hose is therefore subject to various constraints which
découlent de l'articulation entre les deux parties du châssis. arise from the articulation between the two parts of the chassis.
Du fait de la fonction qui leur est assignée, les véhicules de voiries sont très dépendants de la configuration et de l'encombrement des voies sur lesquelles ils se déplacent. Ils sont amenés a effectuer des virages fréquents et brusques, et des mouvements de braquage de forte amplitude, par exemple pour éviter un obstacle ou contourner un véhicule garé le long Due to the function assigned to them, road vehicles are very dependent on the configuration and size of the tracks on which they move. They are required to make frequent and sudden turns, and large amplitude turning movements, for example to avoid an obstacle or to bypass a vehicle parked along
d'un trottoir.a sidewalk.
Les tuyaux d'aspiration sont de ce fait exposés à des chocs et des As a result, the suction hoses are exposed to shocks and
contraintes répétés, et leur durée de vie s'en trouve fortement limitée. repeated stresses, and their lifespan is greatly limited.
Pour remédier à ces inconvénients, on a cherché à remplacer les tuyaux flexibles par des éléments moins fragiles, composés de plusieurs conduits To remedy these drawbacks, attempts have been made to replace flexible pipes with less fragile elements, composed of several conduits.
rigides ou semi-rigides, assemblés entre eux par des coudes. rigid or semi-rigid, joined together by elbows.
Cette solution n'est pas pleinement satisfaisante. En effet, les points de liaison entre les éléments tubulaires rigides et les parties coudées constituent autant de zones d'affaiblissement, avec des risques de perte This solution is not fully satisfactory. Indeed, the points of connection between the rigid tubular elements and the bent parts constitute as many weakening zones, with risks of loss
d'étanchéité.sealing.
De plus, les parties coudées subissent une forte abrasion sous l'effet des sables et déchets granuleux aspirés, ce qui engendre une usure très rapide. Il est par ailleurs nécessaire de prévoir des roulements périphériques au niveau de la liaison entre deux éléments de conduits, afin d'accompagner In addition, the bent parts undergo a strong abrasion under the effect of the sand and granular waste sucked, which generates a very fast wear. It is also necessary to provide peripheral bearings at the connection between two elements of conduits, in order to accompany
les déplacements et les mouvements du châssis du véhicule. displacements and movements of the vehicle chassis.
Cet agencement pose problème, car l'aspiration des déchets se fait le plus souvent a vitesse élevée, ce qui augmente les risques d'obturation ou de perforation des conduits, dans les parties non rectilignes, et augmente le This arrangement poses a problem, since the suction of the waste is most often done at high speed, which increases the risks of blockage or perforation of the conduits, in the non-straight parts, and increases the
coût de revient des installations.cost of the installations.
L'invention se propose de remédier à ces divers inconvénients en réalisant un dispositif d'aspiration comportant un conduit totalement rectiligne entre The invention proposes to remedy these various drawbacks by producing a suction device comprising a completely rectilinear conduit between
les deux parties du châssis.the two parts of the chassis.
Plus particulièrement, le dispositif selon l'invention comporte un conduit en deux éléments, chaque élément étant totalement solidaire de la partie de châssis à laquelle il est relié, les deux éléments comportant par ailleurs More particularly, the device according to the invention comprises a conduit in two elements, each element being completely integral with the chassis part to which it is connected, the two elements also comprising
des moyens de recouvrements à leurs extrémités libres respectives. covering means at their respective free ends.
