Description

La présente invention concerne un ensemble comprenant une voiture de véhicule ferroviaire et au moins un lest.The present invention relates to an assembly comprising a railway vehicle car and at least one ballast.

Il est connu de l'état de la technique que pour se déplacer sur une voie ferrée, les voitures de véhicule ferroviaire nécessitent un effort de traction suffisant, dépendant de la masse du véhicule et de son adhérence sur la voie.It is known from the state of the art that to move on a railway track, rail vehicle cars require a sufficient tractive effort, depending on the mass of the vehicle and its grip on the track.

Cependant, dans certaines conditions, un véhicule ferroviaire peut présenter un manque d'adhérence à la voie sur laquelle il se déplace. En traction, cela se traduit par un patinage du véhicule sur la voie, compliquant l'accélération du véhicule. En freinage, cela se traduit par un enrayage du véhicule sur la voie, et une distance de freinage plus importante. Ces deux phénomènes ne sont pas souhaitables.However, under certain conditions, a rail vehicle may exhibit a lack of adherence to the track on which it is traveling. In traction, this results in the vehicle slipping on the track, making it more difficult to accelerate the vehicle. When braking, this results in the vehicle jamming on the lane, and a greater braking distance. Both of these phenomena are undesirable.

L'invention a notamment pour but d'améliorer l'adhérence d'une telle voiture de véhicule ferroviaire, de façon simple et rapide.The object of the invention is in particular to improve the grip of such a rail vehicle carriage, in a simple and rapid manner.

DE 14 55 141 B1 divulgue une voiture de véhicule ferroviaire comprenant un châssis, et le châssis délimite, en sous-châssis, au moins un espace de réception d'un lest. DE 14 55 141 B1 discloses a railway vehicle car comprising a chassis, and the chassis delimits, as a sub-chassis, at least one space for receiving ballast.

A cet effet, l'invention a notamment pour objet un ensemble comprenant une voiture de véhicule ferroviaire et au moins un lest, la voiture comprenant au moins un châssis, le châssis délimitant, en sous-châssis, au moins un espace de réception de l'au moins lest, caractérisé en ce que l'espace de réception comprend un fourreau, et le lest comporte une glissière, le fourreau et la glissière étant complémentaires de sorte que le fourreau est configuré pour recevoir la glissière du lest.To this end, the subject of the invention is in particular an assembly comprising a railway vehicle car and at least one ballast, the car comprising at least one chassis, the chassis delimiting, as a sub-chassis, at least one space for receiving the at least ballast, characterized in that the reception space comprises a sleeve, and the ballast comprises a slide, the sleeve and the slide being complementary so that the sleeve is configured to receive the slide of the ballast.

Ainsi, il est possible d'installer rapidement et simplement au moins un lest en sous-châssis de la voiture, permettant d'augmenter la masse de la voiture et, par voie de conséquence, d'accroître l'effort de traction au démarrage et au freinage de la voiture ce qui en améliore l'adhérence.Thus, it is possible to quickly and simply install at least one ballast in the subframe of the car, making it possible to increase the mass of the car and, consequently, to increase the tractive effort when starting and when the car brakes, which improves grip.

Un ensemble selon l'invention peut comporter en outre l'une ou plusieurs des caractéristiques suivantes, prises seules ou selon toutes combinaisons techniquement envisageables :

  • le châssis délimite quatre espaces de réception d'un lest respectif chacun ;
  • les quatre espaces de réception d'un lest sont agencés deux à deux de part et d'autre d'une ligne médiane longitudinale séparant le châssis en deux moitiés longitudinales ;
  • le châssis s'étend suivant une direction principale longitudinale, entre deux extrémités longitudinales, et ce châssis est propre à recevoir deux bogies, chaque espace de réception d'un lest étant disposés entre les deux bogies ;
  • la voiture est une motrice de véhicule ferroviaire.
  • -la glissière du lest est reçue dans le fourreau de l'espace de réception du lest.
An assembly according to the invention may also comprise one or more of the following characteristics, taken alone or in any technically conceivable combination:
  • the frame defines four spaces for receiving a respective ballast each;
  • the four spaces for receiving a ballast are arranged two by two on either side of a longitudinal center line separating the frame into two longitudinal halves;
  • the frame extends in a main longitudinal direction, between two longitudinal ends, and this frame is capable of receiving two bogies, each space for receiving a ballast being arranged between the two bogies;
  • the car is a railway vehicle motor.
  • the ballast slide is received in the sheath of the ballast receiving space.

Un ensemble selon l'invention peut comporter en outre l'une ou plusieurs des caractéristiques suivantes, prises seules ou selon toutes combinaisons techniquement envisageables :

  • le lest est fixé au châssis par des moyens de fixation comprenant des vis et des écrous ;
  • le ou les lests présentent une masse totale cumulée comprise entre 5000 kg et 7000 kg.
An assembly according to the invention may also comprise one or more of the following characteristics, taken alone or in any technically conceivable combination:
  • the ballast is fixed to the frame by fixing means comprising screws and nuts;
  • the ballast(s) have a total cumulative mass of between 5000 kg and 7000 kg.

L'invention concerne également un procédé de lestage d'une voiture de véhicule ferroviaire, le procédé comprenant :

  • la fourniture d'un ensemble selon l'invention, et
  • l'introduction de la glissière du lest à l'intérieur du fourreau de l'espace de réception du lest.
The invention also relates to a method for ballasting a railway vehicle carriage, the method comprising:
  • the supply of an assembly according to the invention, and
  • the introduction of the ballast slide inside the sheath of the ballast receiving space.

Selon un mode de réalisation particulier du procédé de lestage, le procédé comprend l'utilisation d'un chariot élévateur pour introduire la glissière du lest à l'intérieur du fourreau de l'espace de réception du lest.According to a particular embodiment of the ballasting method, the method comprises the use of a forklift to introduce the slide of the ballast inside the sheath of the space for receiving the ballast.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux figures annexées sur lesquelles :

  • la Figure 1 représente schématiquement un ensemble comprenant une voiture de véhicule ferroviaire et quatre lests selon un mode de réalisation de l'invention ;
  • la Figure 2 représente une vue agrandie de l'ensemble de la Figure 1 au niveau d'un lest.
The invention will be better understood on reading the following description, given solely by way of example and made with reference to the appended figures in which:
  • the Figure 1 schematically represents an assembly comprising a railway vehicle carriage and four ballasts according to one embodiment of the invention;
  • the Figure 2 represents an enlarged view of the entire Figure 1 at the level of a ballast.

On a représenté, sur la figure 1, un ensemble 10 comprenant une voiture 12 de véhicule ferroviaire et quatre lests 14, 15.We have represented, on the figure 1 , an assembly 10 comprising a railway vehicle carriage 12 and four ballasts 14, 15.

Dans la suite de la description, les termes « sur » et « sous » s'entendent par rapport à une orientation normale d'une voiture de véhicule ferroviaire, dans une direction verticale.In the remainder of the description, the terms “over” and “under” are understood relative to a normal orientation of a rail vehicle car, in a vertical direction.

La voiture 12 est propre à se déplacer sur une voie ferrée (non représentée).The car 12 is capable of moving on a railway track (not shown).

De préférence, la voiture 12 est une motrice.Preferably, car 12 is a power car.

La voiture 12 comprend un châssis 16. Le châssis 16 s'étend entre deux extrémités longitudinales 18, 19 suivant une direction principale longitudinale L.The car 12 comprises a chassis 16. The chassis 16 extends between two longitudinal ends 18, 19 in a main longitudinal direction L.

Le châssis 16 est par exemple réalisé en métal.The frame 16 is for example made of metal.

La voiture 12 représentée sur la figure 1 comporte deux bogies 20. Chaque bogie 20 est disposé en sous-châssis à proximité d'une extrémité longitudinale 18, 19 du châssis 16. Chaque bogie comporte des roues 21.The car 12 represented on the figure 1 comprises two bogies 20. Each bogie 20 is arranged as a subframe close to a longitudinal end 18, 19 of the frame 16. Each bogie comprises wheels 21.

Le châssis 16 délimite, en sous-châssis, au moins un espace 22, 23 de réception d'un lest 14, 15.The frame 16 delimits, in the subframe, at least one space 22, 23 for receiving a ballast 14, 15.

De cette manière, il est possible d'augmenter l'adhérence de la voiture 12 de véhicule ferroviaire lorsqu'elle roule sur une voie ferrée et par conséquent d'augmenter l'effort de traction de la voiture 12 en ajoutant au moins un lest 14, 15.In this way, it is possible to increase the grip of the railway vehicle car 12 when it runs on a railway track and consequently to increase the tractive effort of the car 12 by adding at least one ballast 14 , 15.

De préférence, le châssis délimite quatre espaces 22, 23, chacun propre à recevoir un lest 14,15 respectif. Deux de ces espaces 22, 23 sont visibles sur la Figure 1.Preferably, the frame defines four spaces 22, 23, each capable of receiving a respective ballast 14,15. Two of these spaces 22, 23 are visible on the Figure 1 .

De préférence, les quatre espaces 22, 23 sont identiques.Preferably, the four spaces 22, 23 are identical.

Les quatre espaces 22, 23 de réception d'un lest 14,15 sont disposés entre les deux bogies 20.The four spaces 22, 23 for receiving a ballast 14,15 are arranged between the two bogies 20.

De cette manière, la voiture 12, lorsqu'elle est lestée, présente un comportement dynamique stable.In this way, the car 12, when it is ballasted, presents a stable dynamic behavior.

De préférence, les quatre espaces 22, 23 sont disposés deux à deux de part et d'autre d'une ligne médiane longitudinale séparant le châssis 16 en deux moitiés longitudinales.Preferably, the four spaces 22, 23 are arranged in pairs on either side of a longitudinal center line separating the frame 16 into two longitudinal halves.

De préférence, les quatre espaces 22, 23 sont disposés deux à deux de manière symétrique par rapport à la ligne médiane longitudinale.Preferably, the four spaces 22, 23 are arranged two by two symmetrically with respect to the longitudinal center line.

Par exemple, deux espaces 22, 23 d'une même moitié longitudinale sont séparés d'une distance suivant la direction longitudinale L comprise entre 0 et 5 mètres. Par exemple également, deux espaces 22 symétriques par rapport à la ligne médiane longitudinale sont séparés par une distance comprise entre 0 et 3 mètres.For example, two spaces 22, 23 of the same longitudinal half are separated by a distance in the longitudinal direction L of between 0 and 5 meters. Also for example, two spaces 22 symmetrical with respect to the longitudinal center line are separated by a distance of between 0 and 3 meters.

En variante, le châssis délimite deux espaces 22, 23, chacun propre à recevoir un lest 14, 15 respectif.Alternatively, the frame defines two spaces 22, 23, each able to receive a respective ballast 14, 15.

Un exemple d'espace de réception 22, 23 est représenté plus en détail sur la figure 2. Comme indiqué précédemment, les espaces de réception 22, 23 étant similaires, un seul d'entre eux sera décrit en détail ci-dessous.An example of reception space 22, 23 is shown in more detail on the figure 2 . As indicated previously, the reception spaces 22, 23 being similar, only one of them will be described in detail below.

Comme cela est visible sur la Figure 2, chaque espace de réception 22, 23 comprend un fourreau 24.As can be seen on the Figure 2 , each reception space 22, 23 comprises a sheath 24.

Le fourreau 24 présente typiquement deux paires d'éléments de support 26 en forme de L, deux éléments de support 26 d'une paire se faisant face et étant symétriques par rapport à une direction principale du fourreau, de sorte que chaque paire d'éléments de support 26 délimite un espace de réception d'une glissière 28.The sheath 24 typically has two pairs of L-shaped support elements 26, two support elements 26 of a pair facing each other and being symmetrical with respect to a main direction of the sheath, so that each pair of elements of support 26 delimits a space for receiving a slide 28.

Le fourreau 24 est par exemple réalisé en métal.The sheath 24 is for example made of metal.

De préférence, le fourreau 24 est réalisé dans le même matériau que le châssis 16.Preferably, sheath 24 is made of the same material as frame 16.

Le fourreau 24 est configuré pour recevoir un lest 14,15.The sheath 24 is configured to receive a ballast 14.15.

Comme visible sur la Figure 2, le lest 14,15 comporte la glissière 28 destinée à être reçue dans l'espace de réception. A cet effet, le fourreau 24 et la glissière 28 sont complémentaires.As seen on the Figure 2 , the ballast 14,15 comprises the slide 28 intended to be received in the reception space. For this purpose, the sheath 24 and the slide 28 are complementary.

La glissière 28 du lest 14,15 est alors reçue dans le fourreau 24.The slide 28 of the ballast 14,15 is then received in the sheath 24.

La glissière 28 est typiquement un profilé en forme de T dont les branches prennent appui sur les éléments de support 26 du fourreau 24.The slide 28 is typically a T-shaped profile whose branches rest on the support elements 26 of the sheath 24.

Lorsqu'il est reçu dans un espace 22, chaque lest 14,15 présente par exemple, sous la glissière 28, une forme générale trapézoïdale d'épaisseur constante et formant trois angles sensiblement droits.When it is received in a space 22, each ballast 14,15 has for example, under the slide 28, a generally trapezoidal shape of constant thickness and forming three substantially right angles.

Par «angle sensiblement droit», il est entendu que l'angle a une valeur comprise entre 85° et 95°.By “substantially right angle”, it is understood that the angle has a value between 85° and 95°.

En variante, le lest 14,15 présente toute autre forme adaptée.Alternatively, the ballast 14,15 has any other suitable shape.

Chaque lest 14,15 est par exemple réalisé en métal, par exemple en acier.Each ballast 14,15 is for example made of metal, for example steel.

De préférence, le ou les lests 14,15 présentent une masse totale cumulée comprise entre 5000 kg et 7000 kg.Preferably, the ballast(s) 14,15 have a total cumulative mass of between 5000 kg and 7000 kg.

De préférence encore, le ou les lests 14,15 présentent une masse totale cumulée comprise entre 5950 kg et 6050 kg.Preferably again, the ballast(s) 14,15 have a total cumulative mass of between 5950 kg and 6050 kg.

Ainsi, par exemple, en appliquant la formule suivante : μ = Fmax m ∗ g ,

Figure imgb0001
Où : µ est un coefficient d'adhésion de la voiture 12,

  • Fmax est l'effort appliqué aux roues 21 de la voiture 12,
  • m est la masse de la voiture 12,
  • g est l'accélération de la pesanteur ;
  • une augmentation de la masse de la voiture 12 de 84 tonnes à 90 tonnes permet une augmentation d'effort appliqué aux roues 21 de 280 kN à 300 kN, pour un coefficient d'adhésion constant de 34 %.
Thus, for example, by applying the following formula: μ = Fmax m ∗ g ,
Figure imgb0001
 Where: µ is an adhesion coefficient of the car 12,
  • F max is the force applied to wheels 21 of car 12,
  • m is the mass of car 12,
  • g is the acceleration due to gravity;
  • an increase in the mass of the car 12 from 84 tons to 90 tons allows an increase in the force applied to the wheels 21 from 280 kN to 300 kN, for a constant coefficient of adhesion of 34%.

Dans l'exemple des Figures 1 et 2, chacun des quatre lests 14,15 présente une masse comprise entre 1250 kg et 1750 kg, de préférence égale à 1500 kg.In the example of Figures 1 and 2 , each of the four ballasts 14,15 has a mass of between 1250 kg and 1750 kg, preferably equal to 1500 kg.

De manière préférée, le lest 14,15 est fixé au châssis 16, et notamment fixé aux éléments de support 26, par des moyens de fixation 30 comprenant des vis et des écrous.Preferably, the ballast 14, 15 is fixed to the frame 16, and in particular fixed to the support elements 26, by fixing means 30 comprising screws and nuts.

Cela permet de sécuriser la fixation du lest 14,15 à la voiture 12 lorsque la voiture 12 se déplace sur une voie ferrée.This makes it possible to secure the fixing of the ballast 14,15 to the car 12 when the car 12 moves on a railway track.

Un procédé de lestage d'une voiture 12 de véhicule ferroviaire selon l'invention va maintenant être décrit.A method of ballasting a carriage 12 of a railway vehicle according to the invention will now be described.

Le procédé comprend :

  • la fourniture d'un ensemble 10 tel que décrit ci-dessus, et
  • l'introduction de la glissière 28 du lest 14,15 à l'intérieur du fourreau 24 de l'espace 22,23 de réception du lest 14,15.
The process includes:
  • providing an assembly 10 as described above, and
  • the introduction of the slide 28 of the ballast 14.15 inside the sheath 24 of the space 22.23 for receiving the ballast 14.15.

Lorsque le châssis 16 délimite une pluralité d'espaces 22,23 de réception d'un lest 14,15 respectif chacun, l'étape d'introduction de la glissière 28 de chaque lest 14,15 à l'intérieur du fourreau 24 de chaque espace 22,23 de réception d'un lest 14,15 respectif est répété autant de fois que nécessaire en fonction du nombre de lests 14,15 souhaité.When the frame 16 delimits a plurality of spaces 22,23 for receiving a respective ballast 14,15 each, the step of introducing the slide 28 of each ballast 14,15 inside the sheath 24 of each space 22.23 for receiving a respective ballast 14.15 is repeated as many times as necessary depending on the number of ballasts 14.15 desired.

De préférence, le procédé comprend l'utilisation d'un chariot élévateur pour introduire la glissière 28 du lest 14,15 à l'intérieur du fourreau 24 de l'espace 22,23 de réception du lest 14,15.Preferably, the method comprises the use of a forklift to introduce the slide 28 of the ballast 14,15 inside the sheath 24 of the space 22,23 for receiving the ballast 14,15.

Chaque lest 14,15 est ensuite fixé au châssis 16 par les moyens de fixation 30.Each ballast 14,15 is then fixed to the frame 16 by the fixing means 30.

L'installation d'une pluralité de lests sur la voiture 12 est donc simple et rapide, et peut ainsi durer moins d'une heure.The installation of a plurality of ballasts on the car 12 is therefore simple and quick, and can thus last less than an hour.

Pour retirer le lest 14,15, les moyens de fixation 30 du lest 14,15 au châssis 16 sont d'abord retirés.To remove the ballast 14,15, the fixing means 30 of the ballast 14,15 to the frame 16 are first removed.

Puis, la glissière 28 du lest 14,15 est glissée hors du fourreau 24 afin de retirer le lest 14,15 de l'espace de réception 22,23.Then, the slide 28 of the ballast 14,15 is slid out of the sheath 24 in order to remove the ballast 14,15 from the reception space 22,23.

De préférence, un chariot élévateur est utilisé pour retirer le lest 14,15 de l'espace de réception 22,23.Preferably, a forklift is used to remove the ballast 14.15 from the receiving space 22.23.
