Definitions

  • the invention relates to a front structure of a rail vehicle, in particular a locomotive. Furthermore, the invention relates to a rail vehicle with such a front structure. Moreover, the invention relates to a method for producing a front structure of a rail vehicle, in particular a locomotive.
  • Front structures of rail vehicles form the front or in many cases similar shaped rear end of a car body.
  • the front structure may extend longitudinally (i.e., in the direction of travel) of the rail vehicle over an area approximately corresponding to the driver compartment when it is a locomotive or other rail vehicle having a driver compartment.
  • EP 0756979 A1 describes a driver's cab for the body of a rail vehicle, wherein the outer panel is welded to profiles by means of welds and forms a sandwich composite with a core plate.
  • the car body also has sidewall pillars and profiles welded together by means of welds with the outer panel to ensure a good flow of force between these components.
  • the structure in the front region can also be referred to as a front segment structure, since the front structure forms a segment or a section of the car body in the longitudinal direction of the rail vehicle.
  • the invention therefore also relates, in particular, to a body of a rail vehicle with a front structure.
  • US 2007/0261591 A1 describes a passenger rail car whose front end can be bevelled.
  • Eg in Fig. 13 The font is a structure with elongated elements shown, which form a collision zone.
  • DE 10 2006 044 397 A1 describes a head module for a rail vehicle with a safety cell for the driver, which comprises a frontal structure, a longitudinal structure of the rail vehicle spaced rear structure and on both longitudinal sides of the rail vehicle each having a lateral framework structure.

  • the rail vehicle cell is formed with support frame parts attached to the cover layers and provided at the edge on the support frame parts with fitting connections for joining the cell modules.
  • Front structures especially of locomotives, must meet special mechanical requirements.
  • the required dimensional stability must be ensured in normal operation.
  • the front area is designed for a desired behavior on impact. In particular impact energy from different directions must be absorbed in each case and lead to a defined deformation of the front structure, but leave enough room for the people in the front area.
  • the components of the front structure are custom-made items in a few quantities. It is customary to cut the load-bearing parts of the front structure, in particular tubes and struts, by hand to the required length, to weld together, to connect stiffening sheets with the supporting parts and to minimize manufacturing tolerances deviations from the desired shape by subsequent straightening. In this case, a plurality of individual parts is connected to the front structure. It may happen that similar looking items are confused with each other and exchanged, so that e.g. a too short or too long strut is welded to another supporting part.
  • the number of individual parts to be joined together should be reduced and exchanges of similar items should be avoided.

  • the at least one projection and the corresponding recess are matched to one another in such a way that, for the introduction of the projection into the recess, a resistance must be overcome by applying a corresponding force.
  • a clamping effect is created, which holds the projection in the recess or at least supports a retention of the projection in the recess.
  • the projection may be deformed after being inserted into the recess. This also allows a clamping effect to be achieved.
  • an additional securing element to the projection and / or in the region of the recess, for example a securing pin, which is introduced into a passage opening of the projection.

    - au moins un premier (7, 9, 11) des éléments allongés (3, 5, 7, 9, 11) est relié, au niveau d'une zone d'extrémité du premier élément (7, 9, 11), à un deuxième (3, 5) des éléments allongés (3, 5, 7, 9, 11),
    caractérisé en ce
    - qu'au moins une partie faisant saillie (14, 15) est réalisée dans la zone d'extrémité du premier élément allongé (7, 9, 11) et/ou dans une zone de liaison du deuxième (3, 5) élément allongé,
    - qu'au moins un évidement (22, 23) est réalisé dans la zone de liaison du deuxième élément allongé (3, 5) et/ou dans la zone d'extrémité du premier élément allongé (7, 9, 11), lequel évidement correspond à l'au moins une partie faisant saillie (14, 15),
    - que la partie faisant saillie (14, 15) est introduite dans l'évidement (22, 23) et moyennant quoi la liaison des éléments est établie au moins temporairement,
    - qu'aux fins de la fabrication de la structure avant (1; 31), une pluralité de liaisons sont établies, lesquelles sont formées respectivement par une zone d'extrémité d'un premier élément allongé (7, 9, 11) et par une zone de liaison d'un deuxième élément allongé (3, 5) ou d'une autre partie de la structure avant, dans lequel au niveau de chaque liaison, au moins une partie faisant saillie (14, 15) est introduite dans un évidement (22, 23) correspondant de l'autre élément allongé (3, 5) ou de l'autre partie et dans lequel les positions relatives, les formes et/ou les orientations de toutes les parties faisant saillie et/ou de tous les évidements dans la zone d'extrémité ou dans la zone de liaison et, en option, les formes de la zone d'extrémité et de la zone de liaison de chacun des éléments allongés (3, 5, 7, 9, 11) et des parties au sein de la même structure avant (1 ; 31) sont configurées de manière unique et sont adaptées à une seule autre zone de liaison ou zone d'extrémité correspondante d'un autre élément allongé (3, 5, 7, 9, 11) ou d'une autre partie de la structure avant (1; 31) de sorte qu'au sein de la même structure avant (1; 31), la zone d'extrémité puisse être reliée exclusivement à la zone de liaison correspondante et l'au moins une partie faisant saillie (14, 15) venant ainsi en prise avec l'évidement (22, 23) correspondant.
  8. Procédé selon la revendication précédente, dans lequel deux des deuxièmes éléments allongés (3, 5) sont disposés à une distance donnée l'un de l'autre et de manière à s'étendre en particulier approximativement de manière parallèle l'un par rapport à l'autre de sorte que les deux deuxièmes éléments allongés (3, 5)
