Description

Dispositif de protection anti-projection pour engin roulant, et ensemble équipé d'un tel dispositif  Anti-projection device for a rolling machine, and an assembly equipped with such a device
DOMAINE DE L'INVENTION FIELD OF THE INVENTION
L'invention concerne un dispositif de protection anti-projection pour engin roulant, ainsi qu'un ensemble comprenant un engin roulant équipé d'un tel dispositif. The invention relates to an anti-projection device for a rolling machine, and to an assembly comprising a rolling machine equipped with such a device.
Elle concerne plus particulièrement un dispositif de protection comprenant un écran anti-projection, apte à être disposé au moins partiellement à l'arrière de la roue, et des moyens de liaison de l'écran audit engin, cet écran anti- projection présentant une face apte à être tournée vers la roue à protéger et une face opposée appelée dos de l'écran, et les moyens de liaison de l'écran à l'engin étant configurés pour permettre, à l'état couplé de l'écran à l'engin, un déplacement de l'écran entre deux positions, l'une, dite haute, écartée du sol l'autre, dite basse, rapprochée du sol. It relates more particularly to a protection device comprising an anti-projection screen, adapted to be disposed at least partially at the rear of the wheel, and means for connecting the screen to said machine, this anti-projection screen having a face adapted to be turned towards the wheel to be protected and an opposite face called the back of the screen, and the means of connection of the screen to the machine being configured to allow, in the coupled state of the screen to the gear, a displacement of the screen between two positions, one, said high, separated from the ground the other, said low, close to the ground.
ART ANTERIEUR PRIOR ART
Un tel dispositif de protection est connu à travers le document JP 2006 315566. Such a protection device is known from JP 2006 315566.
Les projections provoquées, à l'arrière de l'engin, par un engin roulant sur route mouillée sont, depuis de nombreuses années, source d'accidents. La présence de bavette ou de garde-boue entourant au moins partiellement la ou les roues, au moins arrières dudit engin, permet de réduire les quantités de projections. Toutefois, ces bavettes ou garde-boue doivent être, notamment au niveau de remorques ou semi-remorques de camions, suffisamment éloignés du sol pour éviter un endommagement de ces bavettes ou garde-boue, en particulier lors des opérations de chargement ou de déchargement en quai. De ce fait, le bord libre inférieur de la bavette ou du garde-boue est généralement relativement écarté du sol, laissant libre un angle important de projections. Ces mêmes contraintes s'appliquent aux véhicules, notamment pendant les phases de stationnement de véhicules. The projections caused by a machine traveling on a wet road at the rear of the machine have been a source of accidents for many years. The presence of bib or mudguard at least partially surrounding the wheel or wheels, at least rear of said machine, reduces the amounts of projections. However, these flaps or mudguards must be, particularly at truck trailers or semi-trailers, sufficiently far from the ground to prevent damage to these flaps or mudguards, especially during loading or unloading operations. dock. As a result, the lower free edge of the flap or mudguard is generally relatively spaced from the ground, leaving a large angle of projections free. These same constraints apply to vehicles, especially during vehicle parking phases.

DESCRIPTION DETAILLEE DETAILED DESCRIPTION
Comme mentionné ci-dessus, le dispositif 1 de protection anti-projection, objet de l'invention, est plus particulièrement destiné à équiper un engin 20 roulant qui comprend au moins une roue 21 d'appui au sol. Cet engin 20 roulant peut donc être par exemple une moto, une voiture ou, comme dans l'exemple représenté, un camion, tel qu'un semi-remorque. As mentioned above, the anti-projection device 1, which is the subject of the invention, is more particularly intended to equip a rolling machine which comprises at least one wheel 21 for supporting the ground. This rolling machine can be for example a motorcycle, a car or, as in the example shown, a truck, such as a semi-trailer.
Le dispositif 1 de protection est ici représenté associé à la roue 21 d'appui au sol de l'engin 20 disposée le plus à l'arrière de l'engin 20, pour éviter aux projections résultant de la rotation de la roue de faire saillie de l'arrière de l'engin 20. Ce dispositif comprend un écran 2 anti-projection apte à être disposé au moins partiellement à l'arrière de la roue 21 . Cet écran 2 se présente ici sous forme d'une plaque, avec une face 4 tournée vers la roue 21 à protéger, et une face opposée formant le dos 5 de l'écran. Le dispositif 1 de protection comprend encore des moyens 3 de liaison de l'écran 2 à l'engin. Ces moyens 3 de liaison de l'écran 2 à l'engin sont configurés pour permettre un déplacement de l'écran 2 entre deux positions, l'une dite haute, écartée du sol, à l'état couplé de l'écran 2 à l'engin 20, l'autre dite basse, rapprochée du sol, à l'état couplé de l'écran 2 à l'engin 20. Ces moyens 3 de liaison peuvent affecter un grand nombre de formes. The protection device 1 is here represented associated with the ground support wheel 21 of the machine 20 disposed furthest to the rear of the vehicle 20, to prevent the projections resulting from the rotation of the wheel from protruding from behind the machine 20. This device comprises a screen 2 anti-projection adapted to be disposed at least partially at the rear of the wheel 21. This screen 2 is here in the form of a plate, with a face 4 facing the wheel 21 to protect, and an opposite face forming the back 5 of the screen. The protection device 1 further comprises means 3 for connecting the screen 2 to the machine. These means 3 connecting the screen 2 to the machine are configured to allow a displacement of the screen 2 between two positions, one said high, separated from the ground, in the coupled state of the screen 2 to the machine 20, the other said low, close to the ground, in the coupled state of the screen 2 to the machine 20. These connecting means 3 can affect a large number of forms.
Dans l'exemple représenté aux figures 1 à 5, ces moyens 3 de liaison comprennent un tablier 9 se présentant sous forme d'une plaque. Ce tablier 9 porte des moyens 8 de guidage en déplacement à coulissement de l'écran 2. Ces moyens 8 de guidage se présentent sous forme de deux glissières sensiblement parallèles fixées le long des bords dits longitudinaux du tablier, ces bords longitudinaux du tablier 9 s'étendant verticalement à l'état fixé du tablier 9 à l'engin. Ce tablier 9 peut constituer un premier élément de protection anti-projection. Il est donc positionné verticalement à l'arrière de la roue et est maintenu dans cette position par des moyens de fixation à la carrosserie de l'engin. Il présente donc, de manière similaire à l'écran, une face tournée vers la roue à protéger et une face opposée formant le dos du tablier. In the example shown in Figures 1 to 5, these connecting means 3 comprise an apron 9 in the form of a plate. This apron 9 carries means 8 guiding sliding displacement of the screen 2. These guide means 8 are in the form of two substantially parallel rails attached along the so-called longitudinal edges of the deck, these longitudinal edges of the deck 9 s extending vertically in the fixed state of the apron 9 to the machine. This apron 9 may constitute a first anti-projection protection element. It is therefore positioned vertically at the rear of the wheel and is held in this position by fastening means to the bodywork of the vehicle. It therefore has, similarly to the screen, a face facing the wheel to protect and an opposite face forming the back of the deck.
L'écran 2 s'étend ici entre le tablier 9 et la roue 21 . Cet écran 2 est équipé d'organes rotatifs, tels que des roues ou des galets, qui sont insérés dans les glissières portées par le tablier 9, pour faciliter le déplacement à coulissement de l'écran 2 le long dudit tablier 9. L'écran 2 est ainsi déplaçable en monte et baisse le long du tablier 9 et est apte à passer d'une position haute dans laquelle le dos de l'écran est recouvert au moins partiellement par ledit tablier venant à recouvrement du dos de l'écran, à une position basse dans laquelle il fait saillie du bord transversal inférieur du tablier pour augmenter la surface utile dudit tablier. En position haute, le dos de l'écran peut être recouvert totalement ou partiellement par ledit tablier. The screen 2 extends here between the apron 9 and the wheel 21. This screen 2 is equipped with rotating members, such as wheels or rollers, which are inserted into the slides carried by the apron 9, to facilitate the sliding movement of the screen 2 along said apron 9. The screen 2 is thus movable upward and down along the apron 9 and is able to move from a high position in which the back of the screen is covered at least partially by said apron overlapping the back of the screen, to a low position in which it projects from the lower transverse edge of the apron to increase the surface useful said apron. In the high position, the back of the screen can be completely or partially covered by said apron.
Le dispositif 1 comprend encore des moyens 6 élastiques de rappel de l'écran 2 en position haute. Ces moyens 6 de rappel se présentent sous forme d'un ressort hélicoïdal disposé entre le bord supérieur de l'écran 2 et le bord supérieur du tablier 9. Ces moyens 6 de rappel auraient pu s'étendre entre le bord supérieur de l'écran 2 et la carrosserie de l'engin de manière équivalente. The device 1 further comprises resilient return means 6 of the screen 2 in the high position. These return means 6 are in the form of a helical spring disposed between the upper edge of the screen 2 and the upper edge of the apron 9. These means 6 recall could have extended between the upper edge of the screen 2 and the bodywork of the machine in an equivalent manner.
Enfin, le dispositif comprend une surface 7 portée par l'écran et apte à être exposée au flux d'air généré lors du déplacement en marche avant de l'engin 20 roulant. Cette surface 7 est configurée pour permettre, sous l'action dudit flux d'air, un déplacement de l'écran 2 suivant un sens opposé à l'effort de rappel. Finally, the device comprises a surface 7 carried by the screen and able to be exposed to the air flow generated during the forward movement of the rolling machine. This surface 7 is configured to allow, under the action of said air flow, a displacement of the screen 2 in a direction opposite to the return force.
Dans l'exemple représenté, ledit écran 2 présente en position verticale deux bords 1 1 longitudinaux dits verticaux et deux bords 12 transversaux dits horizontaux. La surface 7 est montée déportée et s'étend au-delà de l'un desdits bords 1 1 longitudinaux et la surface 7 est réalisée sous forme d'une pièce rapportée sur ledit écran 2. En variante, cette surface 7 aurait pu être réalisée d'une seule pièce avec ledit écran 2. In the example shown, said screen 2 has in vertical position two longitudinal edges 1 1 said vertical and two so-called horizontal transverse edges 12. The surface 7 is mounted offset and extends beyond one of said longitudinal edges 1 1 and the surface 7 is made in the form of an insert on said screen 2. As a variant, this surface 7 could have been made in one piece with said screen 2.
En position d'appui au sol de l'engin sur une surface horizontale, la surface 7 portée par l'écran 2 forme une surface inclinée par rapport au plan d'appui au sol de l'engin 20 depuis un point bas avant de l'engin 20 vers un point haut arrière de l'engin 20. In the ground support position of the vehicle on a horizontal surface, the surface 7 carried by the screen 2 forms an inclined surface relative to the ground plane of the machine 20 from a low point before the machine 20 to a rear top point of the machine 20.
Ainsi, la surface 7 est apte, lors de l'entraînement en déplacement en marche avant de l'engin à une vitesse suffisamment élevée par rapport au tarage ou à la raideur du ressort, à entraîner l'écran 2 vers le bas, c'est-à-dire à rencontre de l'action des moyens 6 de rappel. Thus, the surface 7 is suitable, when driving in the forward movement of the machine at a speed sufficiently high compared to the calibration or the spring stiffness, to drive the screen 2 downwards, it that is to say against the action of the means 6 of recall.
L'écran 2 permet, en position basse, de réduire le cône de projections de la roue 21 , comme l'illustrent les figures 3A et 3B où la figure 3A montre l'écran 2 en position basse avec un angle d'ouverture du cône de valeur a1 inférieure au cône de projection de la figure 3B d'angle α2, l'écran étant, en figure 3B, en position haute. Pour limiter la descente de l'écran, les glissières peuvent être fermées à leur extrémité inférieure et ainsi former, par cette extrémité fermée, une butée de fin de course de l'écran 2. The screen 2 allows, in the low position, to reduce the cone of projections of the wheel 21, as illustrated in FIGS. 3A and 3B where FIG. 3A shows the screen 2 in the low position with an opening angle of the cone of value a1 smaller than the projection cone of FIG. 3B of angle α2, screen being, in Figure 3B, in the high position. To limit the descent of the screen, the slides can be closed at their lower end and thus form, by this closed end, a limit stop of the screen 2.
L'écran 2 comporte encore, dans l'exemple représenté à la figure 5, sur sa face 4 tournée vers la roue, des picots qui permettent de guider l'écoulement des eaux projetées par la roue sur ladite face 4 de l'écran 2. Ainsi, à l'arrêt de l'engin, l'écran 2 est en position haute. Dès que l'engin avance à une vitesse suffisamment élevée, l'écran 2 descend jusqu'à éventuellement atteindre une position basse de fin de course, à une vitesse d'avancement prédéterminée de l'engin. De même, dans l'exemple représenté à la figure 7, le dispositif de protection comprend des moyens 15 de guidage de l'air apte à guider au moins une partie du flux d'air généré lors du déplacement en marche avant de l'engin en direction de la surface 7 portée par l'écran. Ces moyens de guidage permettent de s'exonérer de l'obligation d'optimiser la position de la surface 7 portée par l'écran en position haute de l'écran. En effet, par rapport au flux d'air généré lors du déplacement en marche avant de l'engin roulant, il peut être compliqué d'optimiser la position de la surface 7 à la fois en position haute et en position basse de l'écran. Ces moyens de guidage permettent de surmonter cette difficulté. Ces moyens 15 de guidage peuvent affecter un grand nombre de formes. Dans la figure 7, ils sont formés par un simple conduit traversant fixé à l'engin 20 roulant et s'étendant depuis l'avant en direction de l'arrière de la roue 21 d'appui au sol de l'engin pour déboucher au niveau de son extrémité libre dite arrière en regard de la surface 7 portée par l'écran. Ces moyens de guidage auraient également pu être réalisés sous forme d'une plaque déflectrice. The screen 2 further comprises, in the example shown in Figure 5, on its side 4 facing the wheel, pins that guide the flow of water projected by the wheel on said face 4 of the screen 2 Thus, when the machine stops, the screen 2 is in the up position. As soon as the machine advances at a sufficiently high speed, the screen 2 down to possibly reach a low end position, at a predetermined forward speed of the machine. Similarly, in the example shown in FIG. 7, the protection device comprises means 15 for guiding air capable of guiding at least a portion of the air flow generated during the forward movement of the machine. towards the surface 7 carried by the screen. These guiding means make it possible to be exempted from the obligation to optimize the position of the surface 7 carried by the screen in the upper position of the screen. Indeed, with respect to the air flow generated during the forward movement of the rolling machine, it can be complicated to optimize the position of the surface 7 both in the upper position and in the lower position of the screen . These guiding means make it possible to overcome this difficulty. These guide means can affect a large number of shapes. In FIG. 7, they are formed by a simple through duct fixed to the rolling machine and extending from the front toward the rear of the ground support wheel 21 of the vehicle to level of its so-called free end opposite the surface 7 carried by the screen. These guide means could also have been made in the form of a plate deflecting.
Pour parfaire l'ensemble, le dispositif comprend des moyens 13 de verrouillage en position haute de l'écran 2 et des moyens 14 d'acquisition de données représentatives de la pluie, lesdits moyens 13 de verrouillage étant des moyens déverrouillables configurés pour passer de la position verrouillée à la position déverrouillée en fonction de données fournies par les moyens 14 d'acquisition de données. To complete the assembly, the device comprises means 13 for locking in the upper position of the screen 2 and means 14 for data acquisition representative of the rain, said locking means 13 being unlockable means configured to move from the locked position at the unlocked position according to data provided by the data acquisition means 14.
Ces moyens 13 de verrouillage peuvent être formés par un simple électroaimant solidaire du châssis de l'engin ou des moyens 3 de liaison du dispositif à l'engin, et d'une partie métallique de l'écran. Les moyens 14 d'acquisition de données représentatifs de la pluie peuvent quant à eux êtres formés par un capteur de pluie, des moyens de détection de l'actionnement des balais d'essuie-glace ou autres. Au moins une partie des moyens 14 d'acquisition de données représentatives de la pluie peuvent pré équiper l'engin. Dans ce cas, les moyens de verrouillage sont raccordés à ces moyens d'acquisition de données préexistants. These locking means 13 may be formed by a single electromagnet secured to the frame of the machine or means 3 connecting the device to the machine, and a metal portion of the screen. The data acquisition means 14 representative of the rain can in turn be formed by a rain sensor, means for detecting the actuation of the wiper blades or the like. At least part of the data acquisition means 14 representative of the rain can pre equip the machine. In this case, the locking means are connected to these pre-existing data acquisition means.
Dès qu'une donnée représentative de la pluie est fournie, l'électro-aimant cesse d'être alimenté et l'écran est libre de passer de la position haute à la position basse, en fonction de la vitesse d'avancement de l'engin en marche avant. On évite ainsi d'utiliser l'écran 2 lorsque cela n'est pas nécessaire. As soon as a data representative of the rain is supplied, the electromagnet stops being fed and the screen is free to move from the high position to the low position, according to the speed of advance of the gear moving forward. This avoids using the screen 2 when it is not necessary.
Dans l'exemple représenté aux figures 6 à 9, les moyens 6 de rappel se présentent sous forme d'un ressort de torsion enroulé autour d'un axe pivot de liaison du ressort au bas de caisse de la carrosserie de l'engin. Les branches parallèles de ce ressort sont couplées à l'écran au niveau du bord 12 transversal inférieur de l'écran 2. Cet écran 2 est par ailleurs logé de manière déplaçable à coulissement à l'intérieur d'un étui fixé à la carrosserie de l'engin, au niveau du passage de roue dudit engin. Cet étui est un étui mince de type fourreau, positionné à l'arrière de la roue. Cet étui présente une face tournée vers la roue et une face opposée, fixée à la carrosserie, délimitant le passage de roue. Cet étui est ouvert en direction du sol, pour permettre à l'écran de s'y insérer de manière déplaçable à coulissement. L'écran 2 est équipé de manière similaire à ce qui a été décrit ci-dessus d'une surface 7 apte à être exposée au flux d'air généré lors du déplacement en marche avant de l'engin. Le ressort de torsion tend donc à ramener l'écran en position haute, c'est-à- dire dans l'étui, tandis que la surface 7 portée par l'écran 2 tend, en coopération avec le flux d'air, à entraîner vers le bas l'écran dans le sens d'une sortie de l'étui. In the example shown in Figures 6 to 9, the return means 6 are in the form of a torsion spring wound around a pivot pin connecting the spring to the underside of the body of the machine. The parallel branches of this spring are coupled to the screen at the lower transverse edge 12 of the screen 2. This screen 2 is also housed in a displaceably sliding manner inside a holster attached to the body of the machine, at the wheel well of said machine. This case is a thin sheath type case, positioned at the back of the wheel. This case has a face facing the wheel and an opposite face, fixed to the bodywork, defining the passage wheel. This case is open towards the ground, to allow the screen to be inserted in a sliding manner. The screen 2 is equipped in a manner similar to that described above of a surface 7 capable of being exposed to the air flow generated during the forward movement of the machine. The torsion spring thus tends to bring the screen back to the upper position, that is to say in the case, while the surface 7 carried by the screen 2 tends, in cooperation with the air flow, to pull down the screen in the direction of an exit from the holster.
Le ressort forme ainsi, en parallèle de sa fonction de rappel, des moyens de guidage en déplacement à pivotement dudit écran au niveau de la partie d'écran située hors de l'étui. Cet écran 2 est ici réalisé sous forme d'une plaque souple, en raison de la forme cintrée de l'étui. The spring thus forms, in parallel with its return function, guide means pivotally moving said screen at the screen portion located outside the case. This screen 2 is here made in the form of a flexible plate, because of the curved shape of the case.
Comme mentionné ci-dessus, indépendamment de sa forme de réalisation, le dispositif de protection fonctionne comme suit : à l'arrêt de l'engin ou à une vitesse d'avancement de l'engin inférieure à une première valeur prédéterminée fonction de l'effort exercé par les moyens de rappel sur l'écran, l'écran est en position haute. Dès que la vitesse d'avancement de l'engin dépasse ladite première valeur prédéterminée, l'écran tend à s'abaisser. L'abaissement peut se poursuivre au fur et à mesure de l'augmentation de la vitesse d'avancement de l'engin, jusqu'à ce que l'écran atteigne une butée de fin de course correspondant à une deuxième valeur prédéterminée de vitesse d'avancement de l'engin. Dès que l'engin ralentit et que la vitesse repasse en dessous de la deuxième valeur prédéterminée de vitesse d'avancement de l'engin, l'écran se déplace dans le sens d'une élévation, jusqu'à revenir en position haute de départ, lorsque l'engin est à l'arrêt ou que la vitesse d'avancement de l'engin est inférieure à la première valeur de vitesse prédéterminée. Si le dispositif est équipé de moyens de verrouillage de l'écran en position haute, ce déplacement de l'écran ne s'opère que lorsque l'écran a été au préalable libéré. As mentioned above, regardless of its embodiment, the protective device operates as follows: when the machine stops or at a speed of advancement of the machine less than a first predetermined value according to the force exerted by the return means on the screen, the screen is in the up position. As soon as the forward speed of the machine exceeds said first predetermined value, the screen tends to lower. The lowering can continue as the speed of advancement of the machine increases, until the screen reaches a limit stop corresponding to a second predetermined value of speed. progress of the machine. As soon as the machine slows down and the speed returns below the second predetermined speed of advance of the machine, the screen moves in the direction of an elevation, until returning to the starting position when the machine is at a standstill or the forward speed of the machine is less than the first predetermined speed value. If the device is equipped with means for locking the screen in the up position, this movement of the screen takes place only when the screen has been previously released.
