Definitions

  • Figure 1 shows a schematic lateral view of a train 1 having an obstacle deflector 2 which is fixed to the front end of its carbodyshell 4 and is capable of performing the primary task of removing obstacles from the railway track, thus protecting the train 1 from derailment.
  • this obstacle deflector 2 is not capable of protecting the carbodyshell 4 from damages, because it happens quite frequently that obstacles firstly hit the cover panel of the carbodyshell 4 and only later they are pushed away by the obstacle deflector 2.
  • the obstacle deflector 2 is usually placed behind them because otherwise, due to the fact that it is a fixed element, in case of crash events it would restrain the energy absorber elements, not allowing their proper functioning.
  • Figure 3 shows a lateral view of the train 10 with its obstacle deflector 12 placed under energy absorber elements 22, and another opposed train 10' with its obstacle deflector 12' placed under its energy absorber elements 22'.
  • the obstacle deflector 12 of the present invention includes a support member 18 having a buckling-free system, for example a sledge 16 (e.g. a Coradia LINT, a light regional train of Alstom TD), and a shield element 20 fixed to a front end 16a of the sledge 16.
  • the sledge 16 is carried by the support member 18 so as to be slideably movable with respect to the support member 18 between a first position represented on figures 4 and 5 , the above-cited extended position, and a second position represented on figure 6 , the above-cited retracted position.
  • the sledge 16 and the shield 20 together form a sub-assembly 17, movable with respect to support member 18.
  • the support member 18 is arranged to be fixed at a proximal end 18a to a front end of the carbodyshell 14 of the train 10.
  • Figure 7 is a perspective view of an alternative embodiment of the obstacle deflector 12 of the present invention which includes two lateral rods 24 and a supporting member or box 26 arranged to host said rods 24.
  • Two energy absorber elements 22 are distributed on either sides of a central longitudinal axis X14 or carbodyshell 14. For the sake of simplicity energy absorber elements 22 are not represented on figures 8 and 9 .

Claims (8)

  1. Véhicule (10) avec un déflecteur d'obstacle (12), le véhicule ayant une carrosserie (14) avec une extrémité avant, le déflecteur d'obstacle (12) comprenant :
    un élément de support (18, 26) agencé pour être fixé au niveau d'une extrémité proximale (18a) à l'extrémité avant de la carrosserie(14) ;
    un élément mobile (16, 24) supporté par ledit élément de support (18, 26) afin d'être mobile, de manière coulissante, par rapport à l'élément de support (18, 26) ;
    un élément de protection (20) fixé sur une extrémité avant (16a, 24a), de l'élément mobile (16, 24) ;
    dans lequel l'élément mobile (16, 24) est agencé pour se déplacer entre :
    une position étendue, dans laquelle l'élément de protection (20) est espacé d'une extrémité distale (18b, 26b) de l'élément de support (18, 26) et est agencé pour éloigner un obstacle placé en face du véhicule ferroviaire (10) ; et
    une position rétractée dans laquelle l'élément de protection (20) est en contact avec l'extrémité distale (18b, 26b) de l'élément de support (18) et est agencé pour ne pas éloigner ledit obstacle,
    dans lequel, lorsque l'élément mobile (16, 24) est dans la position rétractée, l'élément de protection (20) est déplacé vers l'arrière par rapport à la position qu'il a lorsque l'élément mobile (16, 24) est dans la position étendue ;
    dans lequel, dans la position étendue, l'élément de protection (20) est agencé pour faire saillie vers l'avant au-delà d'une extrémité distale (22b) des éléments d'amortisseur (22) fixés sur l'extrémité avant de la carrosserie (14) ; et
    dans la position rétractée, l'élément de protection (20) est agencé pour ne pas faire saillie au-delà de l'extrémité distale (22b) des éléments d'amortisseur (22).
  2. Véhicule selon la revendication 1, dans lequel le mouvement entre la position étendue et la position rétractée est uniquement un mouvement de translation vers l'arrière.
  3. Véhicule selon la revendication 1 ou 2, dans lequel l'élément mobile (16, 24) est agencé pour se déplacer de la position étendue à la position rétractée lorsque la force d'un impact entre un obstacle et l'élément de protection (20) dépasse un seuil prédéterminé.
  4. Véhicule selon la revendication 1, dans lequel l'un desdits éléments d'amortisseur (22) est placé sur l'élément mobile (16, 24) entre deux parties (19) de l'élément de support (18).
  5. Véhicule selon l'une quelconque des revendications précédentes, dans lequel l'élément mobile est un traîneau (16).
  6. Véhicule selon l'une quelconque des revendications précédentes, dans lequel l'élément mobile est formé par deux tiges latérales (24).
  7. Véhicule selon la revendication 6, dans lequel l'élément de support (26) est une boîte de support (26) agencée pour accueillir lesdites tiges latérales (24).
  8. Véhicule selon l'une quelconque des revendications précédentes, dans lequel l'élément mobile (16, 24) et l'élément de protection (20) forment ensemble un sous-ensemble (17) mobile par rapport à l'élément de support (18, 26).
