Definitions
- the present invention relates to the snow removal of road traffic lanes, and more particularly relates to a snow removal trailer intended to be towed by a towing hitch vehicle.
- the snow removal trailer of the document US 2006/0143952 A1 has four wheels selectively orientable by means of orientation.
- the wheels of the snow removal trailer are oriented so that their respective axle axis makes an angle with the first direction which is different from 90 °, the trailer frame pivots freely around the hitch of the towing vehicle.
- the towing vehicle when the towing vehicle is also equipped with a snow plow, it is necessary to avoid a strip of snow between the blade of snow snow removal of the trailer and that of the towing vehicle. To do this, it is necessary to provide some overlap between the area swept by the snow plow of the trailer and the area swept by that of the towing vehicle. Since the end of the snow plow closest to the towing vehicle may be offset to the side of the towing vehicle when the snow removal trailer is swiveled, the towing vehicle shall be equipped with a blade extending in width beyond the towing vehicle and going far enough to the side of the towing vehicle to overlap the snow plow of the trailer. But this increase in the width of the snow plow of the towing vehicle is a hindrance to the handling of the towing vehicle.
- the document US 2001/0023546 A1 describes a snow removal device intended to be towed by a vehicle.
- This device comprises a frame extending in a first direction between a first end and a second end.
- the first end of the chassis is provided with connection means allowing a freely pivotable connection to the coupling of the towing vehicle in a substantially horizontal plane.
- connection means allowing a freely pivotable connection to the coupling of the towing vehicle in a substantially horizontal plane.
- a snow plow orientable relative to the frame In the vicinity of the second end of the frame is suspended a snow plow orientable relative to the frame by pivoting about a substantially vertical direction and centered on the longitudinal center axis of the frame.
- the blade is immobilized in pivoting by rods engaged in holes.
- a problem proposed by the present invention is to design a snow removal trailer intended to be towed by a towing hitch vehicle, effectively limiting the risk of collision between the snow removal trailer and the towing vehicle.
- the present invention aims to allow the clearing of a wide area, without subsistence of a strip of snow between the snow plow of the trailer and the snow plow of the towing vehicle, while limiting the width required for the blade snow removal vehicle.
- the towing vehicle when the towing vehicle is traveling in a straight line while driving the pivoting means, it is possible to ensure that the drawbar remains aligned along the straight trajectory of the towing vehicle, whether in the rest position or in the position snow removal.
- the orientation of the snow plow is then by the relative pivoting of the frame of the trailer and the drawbar around the fourth direction.
- the end closest to the towing vehicle of the snow plow of the trailer is closer to the side of the hitch and the towing vehicle, or even be maintained laterally behind the towing vehicle (that is, without going beyond the straight path beyond the width of the towing vehicle).
- the towing vehicle can thus be equipped with a smaller front snow plow, without a strip of snow remaining between the snow plow of the trailer and the snow plow of the towing vehicle.
- the pivoting means may comprise a first double-acting hydraulic cylinder, one end of which is fixed to the drawbar and the other end of which is fixed to the chassis, able to move the drawbar pivotally between its ends. transport and snow clearing positions, and to set the relative angular position of the trailer frame and the drawbar.

- the locking bar makes it possible to immobilize the drawbar in the transport position, to avoid any unwanted pivoting of the snow removal trailer in the event of a failure or an untimely urging of the pivoting means.
- the drawbar and the frame can be brought back (manually for example) to the transport position, then locked in the transport position to allow the operator to safely tow the snow removal trailer to a maintenance center.
- the orientation means may comprise a second double-acting hydraulic cylinder, one end of which is fixed to the chassis and the other end of which is coupled to the axle axis around which the wheel rotates, capable of displacing the wheel.
- axle of the wheel between its first and second positions by pivoting about a pivot direction substantially perpendicular to the plane defined by the first direction and the axle axis of the wheel.
- the snow removal trailer may comprise an immobilization bar in orientation, of fixed length, one end of which may be coupled to the axle axis around which the wheel rotates and the other end may to be fixed on the chassis, to immobilize in orientation the wheel in first position.
- the immobilization bar in orientation makes it possible to immobilize in orientation the wheel in the first position, to avoid any untimely pivoting of the wheel in the event of failure of the orientation means.
- the wheel in the event of failure of the orientation means following the use of the trailer for plowing the snow, the wheel can be brought back (manually for example) to the first position, then be immobilized in the first position to allow the operator safely tow the snow removal trailer to a service center.
- said at least one snow plow may be pivotally articulated on the frame and be displaceable, by displacement means, around a fifth direction substantially parallel to the first direction, between a rest position and a position of job.
- the snow blade is thus retractable by a very simple movement to be mechanically made to come to the side of the frame of the snow removal trailer in the working position.
- the snow plow being located at least partly above the at least one wheel disposed in the first position, the risk of a collision between the snow plow in the rest position with an object beside which the snow removal trailer passes is reduced. And the working edge of the snow blade in the rest position being located higher than the wheels in the fourth direction, it is thus possible to give the snow removal trailer a width little less than or equal to the maximum width authorized by the road regulations, so that it has an optimal lateral balance.
- the snow removal trailer may comprise locking means of the snow plow blade in the rest position.
- the means of locking enable the snow plow to be immobilized in the rest position and to avoid any inadvertent movement of the plow blade towards its working position, in particular when the towing vehicle is traveling with the drawbar and chassis aligned (transport position) for go to the site to clear snow or return.
- the snow plow can be brought back (manually for example) to the rest position, then be immobilized in the rest position to allow the operator to travel safely with the snow removal trailer.
- the snow removal trailer may include a device for projecting a substance such as salt or sand, whose longitudinal position on the chassis is adjustable in translation in the first direction.
- a device for projecting a substance such as salt or sand
- a plurality of wheels makes it possible to better balance the snow removal trailer and to better support its load, especially when it carries a device for projecting a substance such as salt or sand with a reservoir of salt or water. sand.
- the orientation means and / or the pivoting means may be powered by at least one hydraulic pump carried by the frame.
- the snow removal trailer is thus provided with the means necessary to ensure the orientation of said at least one wheel and / or the relative pivoting of the frame and the drawbar. It can thus be used behind any towing vehicle when the driver is provided with remote control means for controlling the hydraulic pump.
- the snow removal trailer may comprise synchronized steering means orientation means and pivoting means. This avoids subjecting the orientation means and the pivoting means unnecessarily high forces when the trailer frame is relatively pivoted relative to the drawbar.
- the first and second fluid compressors are part of a single double hydraulic pump, which is more compact and more economical.
- the snow removal trailer may comprise safety means capable of simultaneously controlling the displacement of the drawbar to its transport position, the displacement of the wheel to its first position, and the movement of the snow plow towards its position. rest position.
- safety means capable of simultaneously controlling the displacement of the drawbar to its transport position, the displacement of the wheel to its first position, and the movement of the snow plow towards its position. rest position.
- Such means are particularly useful in the case of an emergency (such as an obstacle for example) requiring rapid recall of the snow removal trailer in position behind the towing vehicle and the removal of the snow plow.

La présente invention concerne le déneigement des voies de circulation routières, et concerne plus particulièrement une remorque de déneigement destinée à être tractée par un véhicule à attelage de remorquage.The present invention relates to the snow removal of road traffic lanes, and more particularly relates to a snow removal trailer intended to be towed by a towing hitch vehicle.
Pour déneiger simultanément plusieurs files d'une voie de circulation à l'aide d'un seul véhicule tracteur, on connaît une remorque de déneigement telle que décrite dans le document
- un châssis s'allongeant selon une première direction et comportant une lame de déneigement,
- au moins une roue portant le châssis, ladite roue étant sélectivement orientable par des moyens d'orientation entre une première position, dans laquelle l'axe d'essieu autour duquel tourne la roue est perpendiculaire à la première direction, et au moins une deuxième position, dans laquelle l'axe d'essieu autour duquel tourne la roue fait un angle avec la première direction qui est différent de 90°,
- un timon d'attelage s'allongeant selon une deuxième direction entre des première et deuxième extrémités,
- à la première extrémité du timon d'attelage, des premiers moyens de connexion autorisant une liaison librement pivotante à l'attelage du véhicule tracteur autour d'une troisième direction sensiblement perpendiculaire au plan défini par la première direction et l'axe d'essieu autour duquel tourne ladite au moins une roue.
- a frame extending in a first direction and having a snow plow,
- at least one wheel carrying the frame, said wheel being selectively orientable by means of orientation between a first position, in which the axle axis about which the wheel rotates is perpendicular to the first direction, and at least a second position in which the axle axis around which the wheel rotates is at an angle to the first direction which is different from 90 °,
- a drawbar extending in a second direction between first and second ends,
- at the first end of the drawbar, first connecting means allowing a freely pivotable connection to the coupling of the towing vehicle around a third direction substantially perpendicular to the plane defined by the first direction and the axle axis around which turns the at least one wheel.
En l'occurrence, la remorque de déneigement du document
Lors de ce pivotement du châssis de la remorque, il faut éviter que la lame de déneigement portée par la remorque vienne heurter la face arrière du véhicule tracteur. Pour ce faire, le document
Il est ainsi possible d'orienter angulairement la remorque de déneigement encore plus à l'écart de la direction de progression du véhicule tracteur, et donc de déneiger la voie de circulation sur une plus grande largeur.It is thus possible to angularly orient the snow removal trailer even further away from the direction of progression of the towing vehicle, and thus to clear the snow lane over a greater width.
Mais, lorsque le véhicule tracteur est également équipé d'une lame de déneigement, il faut éviter que subsiste une bande de neige entre la lame de déneigement de la remorque et celle du véhicule tracteur. Pour ce faire, il faut prévoir un certain recouvrement entre la zone balayée par la lame de déneigement de la remorque et la zone balayée par celle du véhicule tracteur. L'extrémité de la lame de déneigement la plus proche du véhicule tracteur pouvant être déportée sur le côté du véhicule tracteur lorsque la remorque de déneigement est pivotée, il faut équiper le véhicule tracteur d'une lame s'étendant en largeur au-delà du véhicule tracteur et allant assez loin sur le côté du véhicule tracteur pour venir à recouvrement de la lame de déneigement de la remorque. Mais cette augmentation de la largeur de la lame de déneigement du véhicule tracteur constitue une gêne pour le maniement du véhicule tracteur.However, when the towing vehicle is also equipped with a snow plow, it is necessary to avoid a strip of snow between the blade of snow snow removal of the trailer and that of the towing vehicle. To do this, it is necessary to provide some overlap between the area swept by the snow plow of the trailer and the area swept by that of the towing vehicle. Since the end of the snow plow closest to the towing vehicle may be offset to the side of the towing vehicle when the snow removal trailer is swiveled, the towing vehicle shall be equipped with a blade extending in width beyond the towing vehicle and going far enough to the side of the towing vehicle to overlap the snow plow of the trailer. But this increase in the width of the snow plow of the towing vehicle is a hindrance to the handling of the towing vehicle.
Le document
Un problème proposé par la présente invention est de concevoir une remorque de déneigement destinée à être tractée par un véhicule à attelage de remorquage, permettant de limiter efficacement les risques de collision entre la remorque de déneigement et le véhicule tracteur.A problem proposed by the present invention is to design a snow removal trailer intended to be towed by a towing hitch vehicle, effectively limiting the risk of collision between the snow removal trailer and the towing vehicle.
Simultanément, la présente invention vise à permettre le déneigement d'une zone large, sans subsistance d'une bande de neige entre la lame de déneigement de la remorque et la lame de déneigement du véhicule tracteur, tout en limitant la largeur nécessaire pour la lame de déneigement du véhicule tracteur.Simultaneously, the present invention aims to allow the clearing of a wide area, without subsistence of a strip of snow between the snow plow of the trailer and the snow plow of the towing vehicle, while limiting the width required for the blade snow removal vehicle.
Pour atteindre ces objets ainsi que d'autres, l'invention propose une remorque de déneigement destinée à être tractée par un véhicule à attelage de remorquage, ladite remorque de déneigement comportant :
- un châssis s'allongeant selon une première direction et comportant une lame de déneigement,
- au moins une roue portant le châssis, l'essieu de ladite roue étant sélectivement orientable par des moyens d'orientation entre une première position, dans laquelle l'axe d'essieu autour duquel tourne la roue est perpendiculaire à la première direction, et au moins une deuxième position, dans laquelle l'axe d'essieu autour duquel tourne la roue fait un angle avec la première direction qui est différent de 90°,
- un timon d'attelage s'allongeant selon une deuxième direction entre des première et deuxième extrémités,
- à la première extrémité du timon d'attelage, des premiers moyens de connexion autorisant une liaison librement pivotante à l'attelage du véhicule tracteur autour d'une troisième direction sensiblement perpendiculaire au plan défini par la première direction et l'axe d'essieu autour duquel tourne ladite au moins une roue ; selon l'invention :
- à sa deuxième extrémité, le timon d'attelage est articulé au châssis à pivotement autour d'une quatrième direction sensiblement perpendiculaire au plan défini par la première direction et l'axe d'essieu autour duquel tourne ladite au moins une roue,
- des moyens de pivotement permettent de sélectivement déplacer à pivotement le châssis de remorque par rapport au timon d'attelage, et de fixer la position angulaire relative du châssis de remorque et du timon d'attelage, entre une position de transport, dans laquelle les première et deuxième directions sont sensiblement parallèles, et au moins une position de déneigement, dans laquelle les première et deuxième directions font un angle non nul entre elles.
- a frame extending in a first direction and having a snow plow,
- at least one wheel carrying the frame, the axle of said wheel being selectively orientable by means of orientation between a first position, in which the axle axis about which the wheel rotates is perpendicular to the first direction, and minus a second position, in which the axle axis around which the wheel rotates is at an angle to the first direction which is different from 90 °,
- a drawbar extending in a second direction between first and second ends,
- at the first end of the drawbar, first connecting means allowing a freely pivotable connection to the coupling of the towing vehicle around a third direction substantially perpendicular to the plane defined by the first direction and the axle axis around which turns said at least one wheel; according to the invention:
- at its second end, the drawbar is articulated to the frame pivotally about a fourth direction substantially perpendicular to the plane defined by the first direction and the axle axis around which the at least one wheel rotates,
- pivot means for selectively pivotally moving the trailer frame relative to the drawbar, and for securing the relative angular position of the trailer frame and the drawbar, between a transport position, in which the first and second directions are substantially parallel, and at least one snow clearing position, wherein the first and second directions form a non-zero angle therebetween.
Avec une telle remorque de déneigement, lorsque le véhicule tracteur circule en ligne droite en pilotant les moyens de pivotement, on peut faire en sorte que le timon reste aligné selon la trajectoire rectiligne du véhicule tracteur, que ce soit en position de repos ou en position de déneigement. L'orientation de la lame de déneigement se fait alors par le pivotement relatif du châssis de la remorque et du timon autour de la quatrième direction. Pour une même angulation de la lame de déneigement par rapport à la trajectoire du véhicule tracteur, l'extrémité la plus proche du véhicule tracteur de la lame de déneigement de la remorque est plus proche latéralement de l'attelage et du véhicule tracteur, voire peut être maintenue latéralement derrière le véhicule tracteur (c'est-à-dire sans dépasser à l'écart de la trajectoire rectiligne au-delà de la largeur du véhicule tracteur). Le véhicule tracteur peut ainsi être équipé d'une lame frontale de déneigement moins large, sans que subsiste une bande de neige entre la lame de déneigement de la remorque et la lame de déneigement du véhicule tracteur.With such a snow removal trailer, when the towing vehicle is traveling in a straight line while driving the pivoting means, it is possible to ensure that the drawbar remains aligned along the straight trajectory of the towing vehicle, whether in the rest position or in the position snow removal. The orientation of the snow plow is then by the relative pivoting of the frame of the trailer and the drawbar around the fourth direction. For the same angulation of the snow plow relative to the trajectory of the towing vehicle, the end closest to the towing vehicle of the snow plow of the trailer is closer to the side of the hitch and the towing vehicle, or even be maintained laterally behind the towing vehicle (that is, without going beyond the straight path beyond the width of the towing vehicle). The towing vehicle can thus be equipped with a smaller front snow plow, without a strip of snow remaining between the snow plow of the trailer and the snow plow of the towing vehicle.
Et l'articulation du timon et du châssis peut être utilisée pour circuler plus aisément avec la remorque dans les virages ou carrefours giratoires.And the articulation of the drawbar and the chassis can be used to circulate more easily with the trailer in turns or roundabouts.
De préférence, les moyens de pivotement peuvent comporter un premier vérin hydraulique double effet dont une extrémité est fixée sur le timon d'attelage et dont l'autre extrémité est fixée sur le châssis, apte à déplacer à pivotement le timon d'attelage entre ses positions de transport et de déneigement, et à fixer la position angulaire relative du châssis de remorque et du timon d'attelage. Les moyens de pivotement ont ainsi une structure simple et robuste, et sont en outre très simples à piloter.Preferably, the pivoting means may comprise a first double-acting hydraulic cylinder, one end of which is fixed to the drawbar and the other end of which is fixed to the chassis, able to move the drawbar pivotally between its ends. transport and snow clearing positions, and to set the relative angular position of the trailer frame and the drawbar. The pivoting means and have a simple and robust structure, and are also very simple to control.
Avantageusement, la remorque de déneigement peut comporter une barre de verrouillage de timon, ayant une longueur fixe, dont une extrémité peut être fixée sur le timon d'attelage et dont l'autre extrémité peut être fixée sur le châssis pour immobiliser le timon d'attelage et le châssis en position de transport.Advantageously, the snow removal trailer may comprise a drawbar locking bar having a fixed length, one end of which may be fixed to the drawbar and the other end of which may be fixed to the chassis to immobilize the drawbar of the drawbar. hitch and chassis in transport position.
La barre de verrouillage permet d'immobiliser le timon d'attelage en position de transport, pour éviter tout pivotement intempestif de la remorque de déneigement en cas de défaillance ou de sollicitation intempestive des moyens de pivotement. Par exemple, en cas de défaillance des moyens de pivotement suite à l'utilisation de la remorque pour déneiger, le timon et le châssis peuvent être ramenés (manuellement par exemple) en position de transport, puis être verrouillés en position de transport afin de permettre à l'opérateur de tracter sans risque la remorque de déneigement jusqu'à un centre de maintenance.The locking bar makes it possible to immobilize the drawbar in the transport position, to avoid any unwanted pivoting of the snow removal trailer in the event of a failure or an untimely urging of the pivoting means. For example, in the event of failure of the pivoting means following the use of the trailer for plowing snow, the drawbar and the frame can be brought back (manually for example) to the transport position, then locked in the transport position to allow the operator to safely tow the snow removal trailer to a maintenance center.
De préférence, les moyens d'orientation peuvent comporter un deuxième vérin hydraulique double effet dont une extrémité est fixée sur le châssis et dont l'autre extrémité est couplée à l'axe d'essieu autour duquel tourne la roue, apte à déplacer l'essieu de la roue entre ses première et deuxième positions par pivotement autour d'une direction de pivotement sensiblement perpendiculaire au plan défini par la première direction et l'axe d'essieu de la roue. Les moyens d'orientation ont ainsi une structure simple et robuste, et sont en outre très simples à piloter.Preferably, the orientation means may comprise a second double-acting hydraulic cylinder, one end of which is fixed to the chassis and the other end of which is coupled to the axle axis around which the wheel rotates, capable of displacing the wheel. axle of the wheel between its first and second positions by pivoting about a pivot direction substantially perpendicular to the plane defined by the first direction and the axle axis of the wheel. The orientation means thus have a simple and robust structure, and are also very simple to control.
Avantageusement, la remorque de déneigement peut comporter une barre d'immobilisation en orientation, de longueur fixe, dont une extrémité peut être couplée à l'axe d'essieu autour duquel tourne la roue et dont l'autre extrémité peut être fixée sur le châssis, pour immobiliser en orientation la roue en première position.Advantageously, the snow removal trailer may comprise an immobilization bar in orientation, of fixed length, one end of which may be coupled to the axle axis around which the wheel rotates and the other end may to be fixed on the chassis, to immobilize in orientation the wheel in first position.
La barre d'immobilisation en orientation permet d'immobiliser en orientation la roue en première position, pour éviter tout pivotement intempestif de la roue en cas de défaillance des moyens d'orientation. Par exemple, en cas de défaillance des moyens d'orientation suite à l'utilisation de la remorque pour déneiger, la roue peut être ramenée (manuellement par exemple) en première position, puis être immobilisée en première position afin de permettre à l'opérateur de tracter sans risque la remorque de déneigement jusqu'à un centre de maintenance.The immobilization bar in orientation makes it possible to immobilize in orientation the wheel in the first position, to avoid any untimely pivoting of the wheel in the event of failure of the orientation means. For example, in the event of failure of the orientation means following the use of the trailer for plowing the snow, the wheel can be brought back (manually for example) to the first position, then be immobilized in the first position to allow the operator safely tow the snow removal trailer to a service center.
De préférence, ladite au moins une lame de déneigement peut être articulée à pivotement sur le châssis et être déplaçable, par des moyens de déplacement, autour d'une cinquième direction sensiblement parallèle à la première direction, entre une position de repos et une position de travail.Preferably, said at least one snow plow may be pivotally articulated on the frame and be displaceable, by displacement means, around a fifth direction substantially parallel to the first direction, between a rest position and a position of job.
La lame de déneigement est ainsi escamotable par un mouvement très simple à réaliser mécaniquement pour venir sur le côté du châssis de la remorque de déneigement en position de travail.The snow blade is thus retractable by a very simple movement to be mechanically made to come to the side of the frame of the snow removal trailer in the working position.
Avantageusement, on peut prévoir que :
- la remorque de déneigement comporte au moins deux roues disposées de part et d'autre du châssis selon une direction transversale de châssis,
- en position de travail, l'arête de travail de la lame de déneigement est située, selon la quatrième direction, sensiblement au niveau de la zone de contact des roues avec la chaussée,
- en position de repos, l'arête de travail de la lame de déneigement est située plus haut que les roues selon la quatrième direction,
- en position de repos, la lame de déneigement est située au moins en partie au-dessus d'une roue disposée en première position.
- the snow removal trailer comprises at least two wheels arranged on either side of the chassis in a transverse chassis direction,
- in the working position, the working edge of the snow plow is located, in the fourth direction, substantially at the contact zone of the wheels with the roadway,
- in the rest position, the working edge of the snow plow is located higher than the wheels in the fourth direction,
- in the rest position, the snow plow is located at least partly above a wheel arranged in the first position.
La lame de déneigement étant située au moins en partie au-dessus de ladite au moins une roue disposée en première position, le risque d'une collision entre la lame de déneigement en position de repos avec un objet à côté duquel passe la remorque de déneigement est réduit. Et l'arête de travail de la lame de déneigement en position de repos étant située plus haut que les roues selon la quatrième direction, il est ainsi possible de conférer à la remorque de déneigement une largeur peu inférieure, voire égale, à la largeur maximale autorisée par la réglementation routière, de façon à ce qu'elle présente un équilibre latéral optimal.The snow plow being located at least partly above the at least one wheel disposed in the first position, the risk of a collision between the snow plow in the rest position with an object beside which the snow removal trailer passes is reduced. And the working edge of the snow blade in the rest position being located higher than the wheels in the fourth direction, it is thus possible to give the snow removal trailer a width little less than or equal to the maximum width authorized by the road regulations, so that it has an optimal lateral balance.
De préférence, la remorque de déneigement peut comporter des moyens de verrouillage de la lame de déneigement en position de repos. Les moyens de verrouillage permettent d'immobiliser la lame de déneigement en position de repos et d'éviter tout déplacement intempestif de la lame de déneigement vers sa position de travail, notamment lorsque le véhicule tracteur circule avec le timon et le châssis alignés (position de transport) pour aller sur le site à déneiger ou en revenir. Et en cas de défaillance des moyens de déplacement suite à l'utilisation de la remorque pour déneiger, la lame de déneigement peut être ramenée (manuellement par exemple) en position de repos, puis être immobilisée en position de repos afin de permettre à l'opérateur de circuler sans risque avec la remorque de déneigement.Preferably, the snow removal trailer may comprise locking means of the snow plow blade in the rest position. The means of locking enable the snow plow to be immobilized in the rest position and to avoid any inadvertent movement of the plow blade towards its working position, in particular when the towing vehicle is traveling with the drawbar and chassis aligned (transport position) for go to the site to clear snow or return. And in the event of failure of the means of displacement following the use of the trailer to clear snow, the snow plow can be brought back (manually for example) to the rest position, then be immobilized in the rest position to allow the operator to travel safely with the snow removal trailer.
Avantageusement, la remorque de déneigement peut comporter un dispositif de projection d'une substance telle que du sel ou du sable, dont la position longitudinale sur le châssis est réglable en translation selon la première direction. L'ajustement de la position longitudinale du dispositif de projection sur le châssis, en fonction de la position angulaire relative du châssis de remorque et du timon d'attelage, permet de positionner le dispositif de projection de façon qu'il répartisse le mieux possible sur la chaussée la substance projetée.Advantageously, the snow removal trailer may include a device for projecting a substance such as salt or sand, whose longitudinal position on the chassis is adjustable in translation in the first direction. The adjustment of the longitudinal position of the projection device on the chassis, as a function of the relative angular position of the trailer frame and the drawbar, makes it possible to position the projection device so that it distributes as well as possible on pavement the projected substance.
De préférence, on peut prévoir que :
- la remorque de déneigement comporte plusieurs roues tournant chacune autour d'un axe d'essieu respectif,
- chaque essieu de roue est sélectivement orientable par les moyens d'orientation à pivotement autour d'une direction respective de pivotement sensiblement perpendiculaire au plan défini par la première direction et son axe d'essieu.
- the snow removal trailer has a plurality of wheels each rotating about a respective axle axis,
- each wheel axle is selectively orientable by the pivoting means about a respective pivoting direction substantially perpendicular to the plane defined by the first direction and its axle axis.
Une pluralité de roues permet de mieux assurer l'équilibre de la remorque de déneigement et de mieux soutenir sa charge, surtout lorsqu'elle porte un dispositif de projection d'une substance telle que du sel ou du sable avec un réservoir de sel ou de sable.A plurality of wheels makes it possible to better balance the snow removal trailer and to better support its load, especially when it carries a device for projecting a substance such as salt or sand with a reservoir of salt or water. sand.
Avantageusement, les moyens d'orientation et/ou les moyens de pivotement peuvent être alimentés par au moins une pompe hydraulique portée par le châssis. La remorque de déneigement est ainsi munie des moyens nécessaires à assurer l'orientation de ladite au moins une roue et/ou le pivotement relatif du châssis et du timon. Elle peut ainsi être utilisée derrière tout véhicule tracteur dès lors que l'on met à disposition du conducteur des moyens de pilotage déportés permettant de commander la pompe hydraulique.Advantageously, the orientation means and / or the pivoting means may be powered by at least one hydraulic pump carried by the frame. The snow removal trailer is thus provided with the means necessary to ensure the orientation of said at least one wheel and / or the relative pivoting of the frame and the drawbar. It can thus be used behind any towing vehicle when the driver is provided with remote control means for controlling the hydraulic pump.
De préférence, la remorque de déneigement peut comporter des moyens de pilotage synchronisé des moyens d'orientation et des moyens de pivotement. On évite ainsi de soumettre les moyens d'orientation et les moyens de pivotement à des efforts inutilement trop importants lors du pivotement relatif du châssis de remorque par rapport au timon d'attelage.Preferably, the snow removal trailer may comprise synchronized steering means orientation means and pivoting means. This avoids subjecting the orientation means and the pivoting means unnecessarily high forces when the trailer frame is relatively pivoted relative to the drawbar.
Avantageusement, on peut prévoir que :
- les moyens d'orientation et les moyens de pivotement sont alimentés par un premier compresseur de fluide,
- les moyens de déplacement de la lame de déneigement sont alimentés par un deuxième compresseur de fluide.
- the orientation means and the pivoting means are powered by a first fluid compressor,
- the means for moving the snow plow are fed by a second fluid compressor.
Les moyens d'orientation et les moyens de pivotement sont ainsi pilotables indépendamment de la lame de déneigement, ce qui permet à l'opérateur d'adapter plus facilement la remorque aux différentes circonstances qu'il peut rencontrer, parmi lesquelles on peut notamment citer :
- un rétrécissement ou un élargissement de la voie, nécessitant un déplacement du châssis de remorque par rapport au timon d'attelage sans que cela nécessite d'interrompre le déblaiement de la neige avec la lame de déneigement,
- l'évitement d'un obstacle indésirable pour la lame mais pouvant passer sous la remorque de déneigement, nécessitant un déplacement de la lame de déneigement vers sa position de repos sans que cela nécessite un déplacement relatif du châssis de remorque par rapport au timon d'attelage.
- a narrowing or widening of the track, necessitating a displacement of the trailer frame relative to the drawbar without this necessitating stopping the clearing of the snow with the snow plow,
- the avoidance of an undesirable obstacle for the blade but which can pass under the snow removal trailer, requiring a displacement of the snow blade to its rest position without this requiring a relative displacement of the trailer frame relative to the drawbar of coupling.
Dans ce cas, on peut de préférence prévoir que les premier et deuxième compresseurs de fluide font partie d'une seule et même pompe hydraulique double, ce qui est plus compact et plus économique.In this case, it can preferably be provided that the first and second fluid compressors are part of a single double hydraulic pump, which is more compact and more economical.
De préférence, la remorque de déneigement peut comporter des moyens de sécurité aptes à commander simultanément le déplacement du timon d'attelage vers sa position de transport, le déplacement de la roue vers sa première position, et le déplacement de la lame de déneigement vers sa position de repos. De tels moyens sont particulièrement utiles dans le cas d'une urgence (telle qu'un obstacle par exemple) nécessitant de rappeler rapidement la remorque de déneigement en position derrière le véhicule tracteur et le retrait de la lame de déneigement.Preferably, the snow removal trailer may comprise safety means capable of simultaneously controlling the displacement of the drawbar to its transport position, the displacement of the wheel to its first position, and the movement of the snow plow towards its position. rest position. Such means are particularly useful in the case of an emergency (such as an obstacle for example) requiring rapid recall of the snow removal trailer in position behind the towing vehicle and the removal of the snow plow.

Sur cette figure, on distingue le premier vérin hydraulique 11 double effet et le deuxième vérin hydraulique 14 double effet, qui sont alimentés de façon simultanée par un diviseur de débit 36 alimenté par un premier distributeur hydraulique 37 (de type électrovanne par exemple) recevant un fluide sous pression d'un premier compresseur de fluide 38. Le diviseur de débit 36 et le premier distributeur hydraulique 37 constituent des moyens de pilotage synchronisés pour les moyens d'orientation 6 et les moyens de pivotement 10.In this figure, there are the first
Sur le schéma de la
Le troisième distributeur hydraulique 41 permet d'alimenter les vérins hydrauliques 24 et 25 dont la sortie de tige (pour amener les lames de déneigement 4 et 5 en position de travail) est synchronisée par un diviseur de débit 44. Les moyens de déplacement 23 des lames de déneigement 4 et 5 sont ainsi alimentés par le deuxième compresseur de fluide 39.The third
Les chambres des vérins hydrauliques 11, 14, 29a et 29b sont alimentées par l'intermédiaire de dispositifs 43 à clapets anti-retour pilotés hydrauliquement.The chambers of the
On voit plus particulièrement sur la
Lorsque les circonstances le nécessitent, les moyens de sécurité peuvent être actionnés par l'utilisateur pour commander simultanément le déplacement du timon d'attelage 8 vers sa position de transport et le déplacement des essieux des roues 6a à 6d vers leur première position, ainsi que le déplacement des lames de déneigement 4 et 5 vers leur position de repos. Pour ce faire, les moyens de sécurité comportent un bouton de commande unique 46 permettant de piloter simultanément les premier et troisième distributeurs hydrauliques 37 et 41 pour déplacer ceux-ci dans leur position « B ». Cela provoque une alimentation des vérins hydrauliques 11, 14, 29a et 29b de façon à rétracter leurs tiges.When the circumstances so require, the safety means may be actuated by the user to control simultaneously the displacement of the
Le quatrième distributeur hydraulique 42 permet de laisser les lames de déneigement 4 et 5 au contact de la chaussée C par le seul effet de leur propre poids (lames dites « flottantes »).The fourth
L'utilisation de la remorque de déneigement 1 va désormais être explicitée à l'aide des
Lorsque l'opérateur souhaite procéder au déneigement sur une largeur supérieure à celle que lui autorise la lame de déneigement 47 de son véhicule tracteur 2, il actionne les moyens de pivotement 10 pour déplacer relativement le châssis 3 et le timon 8 vers une position de déneigement telle qu'illustrée sur la
Lorsque la pompe hydraulique 35 double avec ses premier et deuxième compresseurs 38 et 39 cesse d'alimenter les premier et deuxième vérins hydrauliques 11 et 14, ces derniers maintiennent le timon d'attelage 8 et le châssis 3 en position de déneigement et les essieux des roues 6a à 6d en deuxième position. Lors de leur progression sur la chaussée C selon le mouvement illustré par la flèche 48, le véhicule tracteur 2 et la remorque de déneigement 1 balayent une zone de largeur L augmentée, permettant de déblayer plus d'une voie de circulation. L'extrémité 4a de la lame de déneigement 4 ne vient pas buter contre le véhicule 2 tracteur et s'écarte peu latéralement de l'attelage du véhicule 2, assurant un bon recouvrement R des zones balayées par les lames de déneigement 47 et 4. L'extrémité 4a peut même être située derrière la face arrière du véhicule 2, de sorte qu'une lame 47 encore moins large peut être utilisée.When the
Lors du déblayage de la chaussée C, les roues 6a à 6d maintiennent le châssis 3 de la remorque de déneigement 1 oblique par rapport à la direction de progression du véhicule 2 tracteur.During the clearing of the roadway C, the
Les premiers moyens de connexion 9 à la première extrémité 8a du timon d'attelage 8 assurent en permanence une liaison librement pivotante à l'attelage du véhicule 2 tracteur autour d'une troisième direction III-III. Ainsi, si la remorque de déneigement 1 vient à rencontrer un obstacle imprévu, les risques de détérioration du véhicule 2 tracteur et de son attelage 8 sont réduits.The first connecting
Lorsque le véhicule 2 tracteur et la remorque de déneigement 1 balayent une chaussée C bordée par un fossé (parfois peu perceptible visuellement en raison de la neige le comblant), la zone de largeur L augmentée permet de déblayer de façon satisfaisante le bord de la chaussée C (et même au-delà) sans avoir à faire rouler le véhicule 2 tracteur à proximité immédiate du fossé. On limite ainsi les accidents par basculement du véhicule 2 tracteur dans le fossé bordant la chaussée C.When the
La position longitudinale du dispositif de projection 33 est ajustée selon la première direction I-I de façon à ce que celui-ci reste proche du centre de la chaussée C, pour répartir,de façon la plus homogène possible le sel ou le sable issu du réservoir 32 porté par la remorque de déneigement 1.The longitudinal position of the
Une fois les opérations de déneigement terminées, les moyens d'orientation 7 et les moyens de pivotement 10 ramènent le châssis 3 et le timon d'attelage 8 vers leur position de transport, ainsi que les essieux des roues 6a à 6d en première position. Préalablement ou simultanément, les moyens de déplacement ramènent les lames de déneigement 4 et 5 depuis leur position de travail vers leur position de repos. Une fois les lames de déneigement en position de repos, les moyens de verrouillage 28 immobilisent celles-ci en position de repos.Once the snow removal operations are completed, the orientation means 7 and the pivoting means 10 bring the
Par sécurité, avant de retourner au garage, l'opérateur peut immobiliser le timon d'attelage 8 sur le châssis 3 en position de transport à l'aide de la barre de verrouillage de timon 13, et immobiliser les essieux des roues 6a à 6d en première position à l'aide d'une ou plusieurs barres d'immobilisation en orientation 22a à 22d.For safety, before returning to the garage, the operator can immobilize the
Il doit être noté que la remorque à châssis 3 et timon 8 articulés selon l'invention peut être munie, au lieu et à la place d'une lame de déneigement 4 ou 5, de moyens de nettoyage (tels que des brosses de balayage par exemple, rotatives ou fixes, et/ou des moyens de projection de fluide(s)) de la chaussée C. Il en est de même pour le véhicule tracteur 2 dont la lame de déneigement 47 peut être remplacée par des moyens de nettoyage. Une protection indépendante par brevet pourra ainsi être recherchée pour une telle remorque de nettoyage de la chaussée. Ladite remorque de nettoyage est alors déplaçable entre une position de transport et une position de balayage.It should be noted that the articulated
