Abstract

The tanker has a standard chassis (1) with a standard rear axle (3) level with the tank which carries wheels (4). The standard vehicle tank (2) which rests on the chassis has a capacity which varies according to the type of vehicle. To improve the stability, the vehicle axle is modified by having track wideners (5) interposed between the axle and the wheel. The widener has a width of the order of 10 cm. The modified vehicle tank (2') has a width is at least equal to the overall width of the modified wheel train.

Description

La présente invention concerne un véhicule porteur de citerne, et plus particulièrement, un véhicule de lutte contre l'incendie. The present invention relates to a tank-carrying vehicle, and more particularly, a fire-fighting vehicle.

Quelle que soit leur destination, ces véhicules ont des contraintes qui leur sont propres comme par exemple la rapidité pour atteindre le lieu du sinistre mais également l'efficacité de l'intervention qui est notamment conditionnée par la capacité de leur citerne. Whatever their destination, these vehicles have their own constraints such as for example the speed to reach the place of the disaster but also the effectiveness of the intervention which is notably conditioned by the capacity of their tank.

Pour certains sites privés comme par exemple les aérodromes, il est possible de réaliser des véhicules spécifiques, sans avoir à tenir compte des contraintes générales liées aux véhicules routiers. For certain private sites such as aerodromes, it is possible to make specific vehicles, without having to take into account the general constraints linked to road vehicles.

De ce fait, ces véhicules peuvent répondre à des contraintes relativement sévères et présenter des particularités comme par exemple une très grande stabilité en virage ou atteindre des angles de renversement peu communs. As a result, these vehicles can respond to relatively severe constraints and have special features such as very high cornering stability or reach unusual rollover angles.

En contrepartie, ces véhicules sont relativement coûteux du fait qu'ils sont fabriqués en petite série et qu'ils utilisent des éléments qui ne sont pas standard comme les châssis et les essieux. On the other hand, these vehicles are relatively expensive because they are produced in small series and they use elements which are not standard like the chassis and the axles.

La présente invention propose un véhicule citerne, qui présente l'avantage de répondre à des critères ou normes que seuls des véhicules spéciaux peuvent atteindre, tout en utilisant des composants standard de grande diffusion, comme les châssis et plus particulièrement les essieux. The present invention provides a tank vehicle, which has the advantage of meeting criteria or standards that only special vehicles can achieve, while using standard components of wide distribution, such as chassis and more particularly the axles.

Selon l'invention, ce véhicule comporte, au moins au niveau de la citerne, des élargisseurs de voies interposés entre l'essieu et les roues, et une citerne dont la largeur est au moins égale à la largeur du train de roulement ainsi transformé. According to the invention, this vehicle comprises, at least at the level of the tank, track wideners interposed between the axle and the wheels, and a tank whose width is at least equal to the width of the undercarriage thus transformed.

Cette particularité permet de réaliser un véhicule qui offre une très grande stabilité aussi bien en virage que statique. On atteint par exemple, grâce à l'invention, un angle de renversement de l'ordre de 280 alors qu'un véhicule classique, avec un même châssis et une citerne de même capacité, ne peut dépasser un angle de renversement de 24 .  This feature makes it possible to produce a vehicle which offers very high stability both when cornering and when static. Thanks to the invention, for example, a rollover angle of the order of 280 is reached, whereas a conventional vehicle, with the same chassis and a tank of the same capacity, cannot exceed a rollover angle of 24.

Un tel véhicule offre également l'avantage d'être plus rapide du fait de sa plus grande stabilité en virage. Such a vehicle also offers the advantage of being faster due to its greater stability when cornering.

Cette stabilité découle de la possibilité d'abaisser de façon notable le centre de gravité du véhicule sans grèver son efficacité au niveau de l'intervention puisque la capacité de la citerne reste du même ordre de celle d'un véhicule standard.This stability results from the possibility of significantly lowering the center of gravity of the vehicle without compromising its effectiveness at the intervention level since the capacity of the tank remains of the same order as that of a standard vehicle.

Ce véhicule présente donc l'avantage d'utiliser un châssis et des composants standard. I1 utilise également une citerne qui correspond pratiquement à la citerne utilisée sur les véhicules spéciaux de grande largeur. This vehicle therefore has the advantage of using a standard chassis and components. It also uses a tank which practically corresponds to the tank used on special wide vehicles.

Le coût de ce type de véhicule, semi-standard, est nettement moindre que le coût d'un véhicule spécial. The cost of this type of semi-standard vehicle is significantly lower than the cost of a special vehicle.

L'invention sera encore détaillée à l'aide de la description suivante et des dessins annexés donnés à titre indicatif et dans lesquels - la figure 1 représente deux demi-vues en coupe transversale : figure la pour un véhicule standard, figure lb pour un véhicule selon l'invention - la figure 2 représente une demi-coupe transversale du véhicule standard lors d'un essai de renversement - la figure 3 représente une demi-coupe du véhicule selon l'invention en essai de renversement également. The invention will be further detailed with the aid of the following description and of the attached drawings given for information only and in which - FIG. 1 represents two half-views in cross section: FIG. 1 a for a standard vehicle, FIG. 1 b for a vehicle according to the invention - Figure 2 shows a half cross-section of the standard vehicle during a rollover test - Figure 3 shows a half section of the vehicle according to the invention in rollover test also.

Un véhicule standard, comme représenté figure la comporte un châssis 1, une citerne 2 ancrée sur le châssis, et au moins un pont arrière 3 équipé de roues 4. A standard vehicle, as shown in FIG. 1 a, comprises a chassis 1, a tank 2 anchored on the chassis, and at least one rear axle 3 equipped with wheels 4.

Ce véhicule standard comporte un essieu 3 que l'on rencontre sur la plupart des véhicules routiers. De même, le châssis 1 peut utiliser des longerons standard que l'on rencontre sur de multiples véhicules ayant un gabarit similaire. This standard vehicle has an axle 3 which is encountered on most road vehicles. Likewise, the chassis 1 can use standard beams which are encountered on multiple vehicles having a similar gauge.

La citerne 2, qui repose sur le châssis, est une citerne dont la capacité varie selon le type de véhicule ; elle est de l'ordre de 10 à 15.000 litres d'eau plus un compartiment pour l'émulseur, de 1.000 à 2.000 litres. Tank 2, which rests on the chassis, is a tank whose capacity varies according to the type of vehicle; it is of the order of 10 to 15,000 liters of water plus a compartment for the foam concentrate, from 1,000 to 2,000 liters.

La figure lb montre le véhicule selon l'invention, qui comporte le même châssis 1 que le véhicule standard et le même essieu 3. FIG. 1b shows the vehicle according to the invention, which has the same chassis 1 as the standard vehicle and the same axle 3.

Pour améliorer la stabilité, l'essieu 3 comporte des moyens en forme d'élargisseurs de voie 5, interposés entre l'essieu et la roue 4. Cet élargisseur de voie 5 a une largeur de l'ordre de 10 cm. To improve stability, the axle 3 includes means in the form of track wideners 5, interposed between the axle and the wheel 4. This track widener 5 has a width of the order of 10 cm.

La citerne 2' du véhicule selon l'invention a une largeur supérieure à la citerne 2 du véhicule standard du fait de l'élargissement de la voie. Aussi, pour une même capacité, on remarque que la hauteur de la citerne du véhicule selon 1 invention est diminuée d'une façon notable ce qui a pour conséquence d'abaisser le centre de gravité G' du véhicule selon l'invention par rapport au centre de gravité b du véhicule standard. The tank 2 'of the vehicle according to the invention has a width greater than the tank 2 of the standard vehicle due to the widening of the track. Also, for the same capacity, it is noted that the height of the tank of the vehicle according to the invention is significantly reduced, which has the consequence of lowering the center of gravity G ′ of the vehicle according to the invention relative to the center of gravity b of the standard vehicle.

Le véhicule standard représenté figure 1 a une largeur qui correspond à la largeur des véhicules routiers standard, c'est-à-dire 2,50 m. Le véhicule selon l'invention peut atteindre une largeur plus importante, se plaçant dans la gamme des véhicules hors-gabarit cette largeur peut atteindre 2,90 m du fait de l'élargissement de la voie mais aussi du fait de l'utilisation par exemple de pneumatiques sensiblement plus larges que ceux utilisés pour les véhicules standard. The standard vehicle shown in Figure 1 has a width which corresponds to the width of standard road vehicles, that is to say 2.50 m. The vehicle according to the invention can reach a greater width, being placed in the range of oversized vehicles this width can reach 2.90 m due to the widening of the track but also due to the use for example tires significantly wider than those used for standard vehicles.

L'amélioration apportée est illustrée figure 2 et figure 3. The improvement made is illustrated in Figure 2 and Figure 3.

On a représenté figure 2, le véhicule standard dont l'angle de renversement se situe aux alentours de 240. FIG. 2 shows the standard vehicle, the tilt angle of which is around 240.

Le véhicule selon l'invention, équipé des élargisseurs 5, a un comportement bien plus intéressant en matière de renversement puisque l'on atteint aisément un angle de l'ordre de 280. The vehicle according to the invention, equipped with wideners 5, has a much more interesting behavior in terms of overturning since an angle of the order of 280 is easily reached.

Les signes de référence insérés après les caractéristiques techniques mentionnées dans les revendications ont pour seul but de faciliter la compréhension de ces dernières et n'en limitent aucunement la portée.  The reference signs inserted after the technical characteristics mentioned in the claims are intended only to facilitate the understanding of the latter and in no way limit their scope.
