Description

La présente invention concerne une voiture de véhicule ferroviaire ayant un dispositif de fixation d'un équipement en sous-châssis de la voiture.The present invention relates to a railway vehicle car having a device for fixing equipment in the sub-frame of the car.

Une voiture motrice de véhicule ferroviaire comporte divers équipements volumineux, notamment pour la mise en oeuvre de moyens de motorisation. En particulier, la voiture comporte un transformateur électrique volumineux. Ainsi, un tel transformateur électrique est particulièrement encombrant lorsqu'il est agencé dans un compartiment machine de la voiture.A railway vehicle power car includes various bulky pieces of equipment, particularly for the implementation of motorization means. In particular, the car features a bulky electrical transformer. Thus, such an electrical transformer is particularly bulky when it is arranged in a machine compartment of the car.

Afin de remédier à cet encombrement, le transformateur électrique (ou autre équipement) est dans certains cas agencé en sous-châssis de la voiture.In order to remedy this bulk, the electrical transformer (or other equipment) is in certain cases arranged in the sub-frame of the car.

A cet effet, on prévoit un dispositif de fixation du transformateur électrique (ou autre équipement) en sous-châssis, comportant des moyens de fixation à ce sous-châssis.For this purpose, a device is provided for fixing the electrical transformer (or other equipment) to the sub-frame, comprising means for fixing to this sub-frame.

Un tel dispositif de fixation ne donne pas entière satisfaction. En effet, en cas d'accident ferroviaire, les moyens de fixation peuvent rompre et lâcher le transformateur électrique. Or, si le transformateur, pesant plusieurs tonnes, tombe sur la voie ferrée, il risque de causer un déraillement du véhicule ferroviaire.Such a fixing device does not give complete satisfaction. Indeed, in the event of a railway accident, the fixing means may break and release the electrical transformer. However, if the transformer, weighing several tonnes, falls on the railway track, it risks causing the railway vehicle to derail.

Les documents CN 102 275 590 A et CN 206 231 384 U décrivent également des exemples de dispositif de fixation.The documents CN 102 275 590 A And CN 206 231 384 U also describe examples of fixing devices.

L'invention a notamment pour but de fournir un dispositif de fixation sécurisé.The invention aims in particular to provide a secure fixing device.

A cet effet, l'invention a notamment pour objet une voiture de véhicule ferroviaire selon la revendication 1.For this purpose, the invention relates in particular to a railway vehicle car according to claim 1.

En cas de rupture des moyens de fixation, l'équipement (par exemple le transformateur) reste porté par les axes antichute, et ne tombe donc pas sur la voie. Le risque de déraillement dû à une telle chute est donc fortement réduit.In the event of breakage of the fixing means, the equipment (for example the transformer) remains supported by the fall protection pins, and therefore does not fall onto the track. The risk of derailment due to such a fall is therefore greatly reduced.

Un dispositif de fixation selon l'invention peut comporter l'une ou plusieurs des caractéristiques suivantes, prises seules ou selon toutes combinaisons techniquement envisageables.

  • Le dispositif de fixation comporte quatre axes antichute, chacun destiné à être agencé à proximité d'un coin de l'équipement, cet équipement présentant une forme générale de parallélépipède.
  • L'équipement est un transformateur électrique.
A fixing device according to the invention may comprise one or more of the following characteristics, taken alone or in any technically conceivable combination.
  • The fixing device comprises four anti-fall axes, each intended to be arranged near a corner of the equipment, this equipment having a general parallelepiped shape.
  • The equipment is an electrical transformer.

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, parmi lesquelles :

  • [Fig 1] La figure 1 est une vue partielle en perspective d'une voiture de véhicule ferroviaire comprenant un dispositif de fixation selon un exemple de mode de réalisation de l'invention ;
  • [Fig 2] La figure 2 est une vue en coupe transversale des moyens de fixation équipant la voiture de la figure 1 ;
  • [Fig 3] La figure 3 est une vue schématique en coupe longitudinale des moyens de fixation équipant la voiture de la figure 1.
The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended figures, among which:
  • [ Figure 1 ] There figure 1 is a partial perspective view of a railway vehicle car comprising a fixing device according to an exemplary embodiment of the invention;
  • [ Figure 2 ] There figure 2 is a cross-sectional view of the fixing means fitted to the car with the figure 1 ;
  • [ Figure 3 ] There Figure 3 is a schematic view in longitudinal section of the fixing means fitted to the car with the figure 1 .

On a représenté sur la figure 1 une voiture 10 de véhicule ferroviaire selon un exemple de mode de réalisation de l'invention.We represented on the figure 1 a rail vehicle car 10 according to an exemplary embodiment of the invention.

La voiture 10 est une voiture motrice. Ainsi, elle comporte des moyens de motorisation, et divers équipements électriques de mise en oeuvre des moyens de motorisation. En particulier, les équipements électriques comportent un transformateur électrique principal 12. Le transformateur électrique principal 12 présente une forme générale de parallélépipède. Ce transformateur électrique principal 12 est classique et ne sera donc pas décrit plus en détail.Car 10 is a power car. Thus, it includes motorization means, and various electrical equipment for implementing the motorization means. In particular, the electrical equipment comprises a main electrical transformer 12. The main electrical transformer 12 has a general parallelepiped shape. This main electrical transformer 12 is classic and will therefore not be described in more detail.

La voiture 10 comporte par ailleurs un châssis 14, formant la structure de la voiture 10, à laquelle sont fixés les divers équipements électriques.The car 10 also includes a chassis 14, forming the structure of the car 10, to which the various electrical equipment is attached.

Comme cela est représenté sur la figure 1, le transformateur électrique principal 12 est agencé en sous-châssis. En d'autres termes, il est agencé sous le châssis 14.As shown on the figure 1 , the main electrical transformer 12 is arranged in a sub-frame. In other words, it is arranged under the chassis 14.

A cet effet, la voiture 10 comporte un dispositif 16 de fixation du transformateur électrique 12 en sous-châssis.For this purpose, the car 10 includes a device 16 for fixing the electrical transformer 12 in the sub-frame.

Le dispositif de fixation 16 comporte quatre parties de fixation identiques, chacune agencée à un coin du transformateur électrique 12. Ces quatre parties de fixation étant identiques, seule l'une d'elles sera décrite, en référence aux figures 2 et 3.The fixing device 16 comprises four identical fixing parts, each arranged at a corner of the electrical transformer 12. These four fixing parts being identical, only one of them will be described, with reference to the figure 2 And 3 .

Le dispositif de fixation 16 comporte des moyens 17 de fixation du transformateur au châssis 14.The fixing device 16 comprises means 17 for fixing the transformer to the chassis 14.

Les moyens de fixation 17 comportent une plaque de fixation 18, destinée à recevoir le transformateur électrique 12. La plaque de fixation 18 est solidarisée au châssis 14, par des moyens de solidarisation classiques 20, par exemple un système de vis/écrous.The fixing means 17 comprise a fixing plate 18, intended to receive the electrical transformer 12. The fixing plate 18 is secured to the chassis 14, by conventional securing means 20, for example a system of screws/nuts.

Avantageusement, les moyens de fixation 17 comportent au moins un organe d'amortissement 22, déformable élastiquement, intercalé entre la plaque de fixation 18 et le transformateur électrique 12. L'organe d'amortissement 22 comporte des plots déformables élastiquement 24, par exemple des plots caoutchoucs. Ces plots déformables 24 sont enserrés entre la plaque de fixation 18 et une contre-plaque 26, par une vis de serrage 28 munie de moyens de vissage 30. Le transformateur électrique 12 est relié aux plots déformables 24 par l'intermédiaire d'au moins un bras de liaison 32 solidarisée d'une part au transformateur électrique 12, et passant par ailleurs à travers les plots déformables 24 dans des orifices prévus à cet effet.Advantageously, the fixing means 17 comprise at least one damping member 22, elastically deformable, interposed between the fixing plate 18 and the electrical transformer 12. The damping member 22 comprises elastically deformable pads 24, for example rubber pads. These deformable blocks 24 are clamped between the fixing plate 18 and a counter-plate 26, by a tightening screw 28 provided with screwing means 30. The electrical transformer 12 is connected to the deformable pads 24 via at least one arm of connection 32 secured on the one hand to the electrical transformer 12, and also passing through the deformable pads 24 in orifices provided for this purpose.

Cette fixation par l'intermédiaire de l'organe d'amortissement 22 permet de limiter, ou supprimer, la transmission, vers le transformateur 12, de chocs, de bruits, de vibrations, etc.This fixing via the damping member 22 makes it possible to limit, or eliminate, the transmission, to the transformer 12, of shocks, noise, vibrations, etc.

Le dispositif de fixation 16 selon l'invention comporte par ailleurs des moyens antichute 35, destinés à empêcher une chute du transformateur 12 en cas de rupture des moyens de fixation 17, par exemple en cas d'accident ferroviaire.The fixing device 16 according to the invention also comprises anti-fall means 35, intended to prevent a fall of the transformer 12 in the event of breakage of the fixing means 17, for example in the event of a railway accident.

Les moyens antichute 35 comportent, pour chaque partie de fixation, au moins un axe antichute 34 monté libre dans des orifices traversant un pied du châssis 14 et traversant un organe de passage 36 associé au transformateur électrique 12, l'axe antichute 34 étant immobilisé suivant son axe longitudinal au pied du châssis 14, comme cela est notamment représenté sur la figure 3. Chaque axe antichute 34 est solidarisé au châssis 14 de toute manière envisageable. Par exemple, l'axe antichute 34 passe dans des orifices ménagés sur ce pied du châssis 14 et cet axe antichute 34 est immobilisé mécaniquement par une liaison vis/écrou au pied du châssis 14.The anti-fall means 35 comprise, for each fixing part, at least one anti-fall axis 34 mounted free in orifices passing through a foot of the chassis 14 and passing through a passage member 36 associated with the electrical transformer 12, the anti-fall axis 34 being immobilized according its longitudinal axis at the foot of the chassis 14, as is particularly represented on the Figure 3 . Each anti-fall axis 34 is secured to the chassis 14 in any conceivable manner. For example, the anti-fall axis 34 passes through orifices provided on this foot of the chassis 14 and this anti-fall axis 34 is mechanically immobilized by a screw/nut connection at the foot of the chassis 14.

Chaque partie de fixation comporte également, pour chaque axe antichute 34, au moins un organe 36 de passage pour l'axe antichute 34, comprenant un orifice 38 de passage de l'axe antichute 34, et solidarisé au transformateur électrique 12.Each fixing part also comprises, for each anti-fall axis 34, at least one passage member 36 for the anti-fall axis 34, comprising an orifice 38 for passing through the anti-fall axis 34, and secured to the electrical transformer 12.

Par exemple, l'organe de passage 36 est solidarisé au transformateur électrique 12 par soudage.For example, the passage member 36 is secured to the electrical transformer 12 by welding.

L'organe de passage 36 présente une forme générale allongée, l'orifice de passage 38 s'étendant sur toute sa longueur.The passage member 36 has a generally elongated shape, the passage orifice 38 extending over its entire length.

Avantageusement, l'orifice de passage 38 présente un diamètre supérieur au diamètre de l'axe antichute 34 correspondant, par exemple au moins 1,2 fois supérieur, de préférence au moins 1,4 fois supérieur. Ainsi, il existe une mobilité possible entre le transformateur 12 et l'axe antichute 34. Cette mobilité permet de ne pas entraver les effets de l'organe d'amortissement 22.Advantageously, the passage orifice 38 has a diameter greater than the diameter of the corresponding anti-fall axis 34, for example at least 1.2 times greater, preferably at least 1.4 times greater. Thus, there is possible mobility between the transformer 12 and the anti-fall axis 34. This mobility makes it possible to not hinder the effects of the damping member 22.

Conformément au mode de réalisation décrit, la voiture 10 s'étendant dans une direction longitudinale X, chaque axe antichute 34 s'étend parallèlement à cette direction longitudinale X.In accordance with the embodiment described, the car 10 extending in a longitudinal direction X, each anti-fall axis 34 extends parallel to this longitudinal direction X.

On notera que l'invention n'est pas limitée au mode de réalisation décrit, mais pourrait présenter diverses variantes.It will be noted that the invention is not limited to the embodiment described, but could present various variants.

En particulier, le dispositif de fixation 16 peut être utilisé pour fixer tout autre équipement envisageable en sous-châssis de la voiture 10.In particular, the fixing device 16 can be used to fix any other possible equipment in the sub-frame of the car 10.
