Abstract
Description
L'invention se rattache au secteur technique des bennes de camions enThe invention relates to the technical sector of truck tippers in
général et plus particulièrement celui des bennes demi-ronde ou parallélépipédiques /tronconiques. Généralement ce type de bennes est levé par general and more particularly that of semi-round or parallelepipedic / frustoconical skips. Generally this type of skips is lifted by
des vérins frontaux télescopiques multi expansion à simple effet. multi-expansion telescopic front jacks with single effect.
Ce dispositif comporte plusieurs inconvénients, notamment par le fait de sa lenteur, des secousses engendrées par les différents étages des vérins lors de son déploiement en levage et en descente par gravité. This device has several disadvantages, in particular because of its slowness, jolts generated by the different stages of the cylinders during its deployment in lifting and descent by gravity.
Le vérin doit en outre contenir les efforts latéraux lorsque le véhicule doit benner sur un sol en dévers. Autre inconvénient, celui de l'absence du contrôle de o l'auto basculement par vérin télescopique à simple effet; il faut savoir que lors du déchargement de la charge transportée, il se produit toujours un effet dit d'auto basculement , surtout lorsque l'on transporte des blocs d'enrochement ou des charges collantes. The cylinder must also contain the lateral forces when the vehicle must benner on a sloping ground. Another disadvantage, that of the lack of control o self tilt by telescopic jack single effect; It should be noted that during the unloading of the transported load, a self-tipping effect always occurs, especially when rock blocks or sticky loads are transported.
Il existe également un dispositif de basculement de bennes à vérins latéraux dont la poussée s'exerce à contrario du sens logique du basculement de la benne; en effet la prise des vérins se-situe vers l'arrière du camion, soit au centre du tandem. La poussée s'exerce alors vers l'avant du véhicule, c'est à dire à contre-sens. There is also a device for tipping skips with side cylinders whose thrust exerted contrario the logical direction of tilting of the bucket; indeed the catch of the jacks is located towards the back of the truck, in the center of the tandem. The thrust is then exerted towards the front of the vehicle, ie against the direction.
Il faut une grande puissance pour contrecarrer les charges qui s'exercent de manière négative vers l'avant. L'effort sur les articulations arrières se trouve démultiplié. Celles-ci doivent supporter conjointement les efforts des vérins et de la charge qui doivent dans un premier temps s'exercer vers l'avant et basculer la caisse vers l'arrière. It takes a great deal of power to counteract the loads that are exerted negatively to the front. The effort on the rear joints is multiplied. These must jointly support the efforts of the cylinders and the load which must initially exert forward and tilt the box backwards.
Autres inconvénients, la triangulation est extrêmement réduite sur le châssis par le fait que la poutre d'assise des vérins est très proche de l'articulation arrière. Les vérins doivent quant à eux assurer seuls la stabilité latérale en cas de dévers, ce qui est en général mal supporté par le système de guidage des dits vérins. Other disadvantages, the triangulation is extremely reduced on the chassis by the fact that the seat beam of the cylinders is very close to the rear articulation. The cylinders must themselves ensure lateral stability in case of cant, which is generally poorly supported by the guide system of said cylinders.
L'articulation inférieure des vérins, située entre les roues est soumise aux projections de boues et gravillons ce qui présente un grave inconvénient pour leur 30 longévité. The lower articulation of the cylinders, located between the wheels is subjected to splashing sludge and gravel which presents a serious disadvantage for their longevity.
Il existe également des dispositifs de levage à vérins latéraux utilisés dans les tombereaux de chantier avec succès. Celui-ci ne peut être utilisé sur les châssis de camion qui doit allier à la fois la souplesse du châssis et de son faux châssis, ainsi que la stabilité latérale lors du bennage. There are also lifting devices with side cylinders used in construction dumpers successfully. It can not be used on truck chassis which must combine both the flexibility of the chassis and its subframe, as well as lateral stability during tipping.
Dans les tombereaux de chantier, la stabilité est obtenue par l'extrême rigidité du châssis, qui supporte la benne directement sans faux châssis. In construction trucks, stability is achieved by the extreme rigidity of the chassis, which supports the bucket directly without false chassis.
Le dessin planche 1/4 représente un dispositif de levage et basculement de benne demi-ronde. La planche 2/4 représente le système de triangulation du dispositif. Les dessins de la planche 3/4 représentent le faux châssis et les longerons. La Planche 4/4 représente le compas stabilisateur. The drawing board 1/4 represents a device for lifting and tipping half-round bucket. Plate 2/4 represents the triangulation system of the device. The drawings in plate 3/4 represent the false frame and the longitudinal members. Plate 4/4 represents the stabilizing compass.
Le dispositif de levage et de basculement, objet de la présente invention, permet de supprimer ces inconvénients. Il se compose principalement de deux vérins latéraux (4) à double effet, montés en oblique, munis de rotules inférieures et supérieures (9). The lifting and tilting device, object of the present invention, eliminates these disadvantages. It consists mainly of two side cylinders (4) double acting, mounted obliquely, with lower and upper ball joints (9).
Ils exercent une poussée en V vers l'arrière de l'articulation inférieure (2), selon l'axe (C) dans le sens logique du basculement. They exert a V-thrust towards the rear of the lower articulation (2), along the axis (C) in the logical direction of the tilting.
des longerons du châssis du véhicule. chassis longitudinal members of the vehicle.
La planche 1/3 représente un véhicule gros porteur à 4 essieux équipé du dispositif associé à une benne demi-ronde. Dans le cas de la présente invention, la poutre de poussée (3) des vérins (4) se situe largement vers l'avant du véhicule, répartissant les efforts sur un grand triangle (A, B, C). The 1/3 board represents a four-axle heavy vehicle equipped with the device associated with a half-round grab. In the case of the present invention, the thrust beam (3) of the cylinders (4) is located largely towards the front of the vehicle, distributing the forces on a large triangle (A, B, C).
Cette poussée est bénéfique à la stabilité du véhicule, car elle transmet un report des charges. Les vérins exercent un appui sur le faux châssis au plus prés du tandem avant, afin de transmettre les efforts sur l'avant du véhicule. En outre, du fait de la conicité de la benne, les vérins suivent celle-ci; cette disposition offre l'avantage d'exercer une poussée divergente en forme de V assurant un meilleur centrage des efforts. This thrust is beneficial to the stability of the vehicle because it transmits a load report. The cylinders exert a support on the false frame closer to the front tandem, in order to transmit the forces on the front of the vehicle. In addition, because of the taper of the bucket, the cylinders follow it; this arrangement offers the advantage of exerting a V-shaped divergent thrust providing better centering of the forces.
La poutre de poussée transversale (3) se trouve réduite en largeur. Pour accroître la stabilité latérale et contenir les effets de vrille de la benne par rapport au châssis du camion, dans les cas de bennage sur sol instable, le dispositif objet de la présente invention a été complété par un compas stabilisateur (6). The transverse thrust beam (3) is reduced in width. To increase the lateral stability and contain the spin effects of the bucket relative to the chassis of the truck, in cases of unstable soil tipping, the device object of the present invention was completed by a stabilizing compass (6).
Ce dispositif particulièrement robuste et indéformable comporte un cadre 70 rigide (11) articulé sur les longerons de la benne (10) et relié au faux châssis (1) par deux bras (12). This particularly robust and indeformable device comprises a rigid frame 70 (11) articulated on the longitudinal members of the bucket (10) and connected to the false frame (1) by two arms (12).
Deux paliers de fixation supérieurs (13) solidarisent le cadre rigide (11) aux longerons de la benne par un axe transversal (14). Deux paliers de fixation inférieurs (15) solidarisent les bras du stabilisateur sur le faux châssis par un axe transversal (16). Two upper fixing bearings (13) secure the rigid frame (11) to the side members of the bucket by a transverse axis (14). Two lower attachment bearings (15) join the stabilizer arms on the subframe by a transverse axis (16).
Le circuit hydraulique équipant le véhicule comporte des valves d'équilibrage et de contrôle de descente montée directement sur chaque vérin au moyen de tuyauteries rigides. The hydraulic system fitted to the vehicle comprises balancing and descent control valves mounted directly on each cylinder by means of rigid pipes.
Ces valves, non représentées sur les dessins, ont pour mission de réguler le débit à la montée et à la descente identique à chaque vérin; elles ont une fonction de blocage et de sécurité en cas de défaillance du circuit ou de rupture d'un flexible. 5o These valves, not shown in the drawings, have the task of regulating the flow rate on the ascent and descent identical to each cylinder; they have a blocking and safety function in case of circuit failure or hose breakage. 5o
Ils prennent appuis sur la poutre de poussée transversale (3), selon l'axe (A) et transmettent leurs efforts sur les rives supérieures de la benne (8) par l'intermédiaire des rotules inférieures et supérieures (9). They take support on the transverse thrust beam (3), along the axis (A) and transmit their efforts on the upper banks of the bucket (8) via the upper and lower ball joints (9).
Le faux châssis (1) , pièce maîtresse dans une benne, sert d'interface à celle-ci pour être associée intimement au châssis du camion. The subframe (1), the centerpiece in a bucket, serves as an interface to it to be intimately associated with the chassis of the truck.
II doit être conçu pour répartir et dissiper les efforts des vérins et le mouvement de la benne, afin d'éviter toute fatigue ponctuelle entraînant la rupture It must be designed to distribute and dissipate the forces of the cylinders and the movement of the bucket, in order to avoid any occasional fatigue resulting in the rupture
