Definitions

  • the present invention relates to a head module for a rail vehicle, in particular for high-speed traffic, according to the preamble of claim 1 with a safety cell for the driver, a frontal structure, a spaced longitudinally of the rail vehicle rear structure and on both longitudinal sides of the rail vehicle each a lateral Truss structure includes, wherein the frontal structure in the center region of the rail vehicle in the direction of the vertical axis of the rail vehicle extends to the height range defined by the lower edge of the windshield of the rail vehicle, and the respective lateral truss structure in the event of a crash, the frontal structure against the rear second structure supported.
  • the invention further relates to a rail vehicle with a head module according to the invention.
  • Such a head module is for example from the EP 0 888 946 B1 known.
  • the frontal structure and the front half of the lateral truss structures of the safety cell extend in the direction of the vertical axis of the rail vehicle to approximately in the height range of the lower edge of the windshield of the rail vehicle.
  • the safety cell surrounds the cab of the driver or is a component of this cabin.
  • Other generic head modules are from the EP 0 802 100 A1 as well as the EP 1 215 098 A1 known.
  • a central function of the safety cell is to provide the driver in the event of a crash sufficiently large survival space in the event that he is no longer able to leave the driver's cab in time for an obstacle to the impact.
  • the safety cell is also plastically deformed to a certain extent in order to absorb part of the impact energy.
  • the TSI High-Speed Rolling Stock proposes three different crash scenarios: Scenario 1: Passenger train versus passenger train at a relative speed of 36 km / h; Scenario 2: Passenger train approaching the end of a freight train (mass 80 t) at one Relative speed of 36 km / h; Scenario 3: Passenger train against a rigid block (mass 15 t) at a relative speed of 110 km / h.
  • Scenario 3 is intended to simulate a collision with an obstacle standing on a railroad crossing, such as a loaded truck. However, this scenario has shown that this scenario only incorrectly simulates the actual conditions in the event of a collision with such an obstacle. Therefore, it is intended to modify this scenario so that the passenger train collides with a deformable obstacle in the form of a tank truck of mass 15 t.
  • the known safety cells provide insufficient protection for the vehicle driver.
  • the deforming obstacle rolls on the vehicle head and deformed areas of the obstacle penetrate deep into the driver's cab, for example via the opening of the windshield.

  • the truss structures can be designed so that they experience a certain plastic deformation in certain areas, which, however, may in any case only be so low that the driver still sufficient survival space is available.
  • the respective truss structure is designed in such a way that, in a given crash situation, it is not plastically deformed substantially with a lateral impact on a standard deformable obstacle simulating a loaded truck.
  • the survival space for the driver is ensured in an advantageous manner. It is preferably provided that these conditions are met, at least for a crash, in which the lateral impact occurs at a relative speed of 110 km / h and the deformable obstacle has a mass of 15 t.
  • the rigid support of the column elements can be done in any suitable manner. It is preferably provided that at least one of the truss structures has a first support element which extends from the upper end region of the associated pillar element downwards in the direction of the rear structure. This is particularly in connection with the support of the obliquely downwardly acting loads by tending to roll obstacle of advantage.
  • the first carrier element can extend up to a further carrier element, for example a carrier of the truss structure running in the longitudinal direction of the rail vehicle.
  • the first support element extends to the rear structure, so that a simple and reliable support is ensured on the rear structure.
  • At least one of the truss structures has a second carrier element which extends from the upper end region of the associated pillar element upwards in the direction of the rear structure.
  • the second support element extends only to a further carrier element, for example a further carrier of the truss structure extending in the longitudinal direction of the rail vehicle.
  • the second carrier element extends up to the rear structure, in order to ensure reliable support on the rear structure in a simple manner.
  • the frontal structure has at least one frontal coupling device defining a front coupling plane running in the direction of the vertical axis of the rail vehicle, in the region of which at least one impact energy absorbing element pointing forwards in the longitudinal direction of the rail vehicle can be coupled to the frontal structure.
  • the respective pillar element has a projection which points forwards in the longitudinal direction of the rail vehicle and projects beyond the coupling plane in the longitudinal direction of the rail vehicle to the front.
  • the projection has a contact region lying in front in the longitudinal direction of the rail vehicle and the distance between the contact region of the projection and the coupling plane in the longitudinal direction of the rail vehicle is dimensioned such that it is greater than the final length of one in the region of Coupling plane mounted impact energy dissipation element in the state of fully utilized energy consumption.
  • the obstacle contacts the projection of the column elements before the energy absorption capacity of the impact energy absorbing element is completely utilized, for example the impact energy dissipation element is completely compressed.
