Definitions

  • the invention relates to an energy dissipation device for a rail vehicle.
  • Rail vehicles especially passenger rail vehicles, are improving in terms of the passive
  • Energy absorption capacity of an energy absorption device is the direction of the acting deformation force. If this does not occur in the intended direction, For example, at an angle or not at the intended force application point, crash modules attached to the end of the vehicle tend to deform only on one side. This has the consequence that the free end of the relevant crash module, which is usually provided with anti-climbing protection, is inclined, significant transverse forces are generated, the energy absorption capacity of the crash module can no longer be fully exhausted and, moreover, the opponents in the crash are at risk because of the now slide oblique contact points on one another.
  • the invention is therefore based on the object of a

  • the buckling plates are provided with a pre-deformation in the direction of a desired deformation direction, and the buckling plates are provided with one another with a tension-pressure means
  • the tension-pressure means transfers the deformation of one buckling plate to the other buckling plate and deforms it so that the baffle plate is displaced parallel with respect to the back plate.
  • An energy dissipation device comprises a back plate which is used for fastening the
  • This fastening can preferably be designed to be detachable by means of screw connections.
  • a permanent connection is also advantageous for certain purposes. The latter is particularly advantageous when the
  • Energy dissipation device is dimensioned so that its triggering leads to further damage to the vehicle structure anyway and a repair of the vehicle no longer
  • a baffle plate for absorbing collision forces which are introduced by an opponent in the collision is provided at a parallel distance from the back plate.
  • This baffle plate is to be made so massive that it
  • the baffle plate can either be made in one piece as a cast steel part or as a welded construction made of steel plates with internal honeycomb reinforcements.
  • At least two buckling plates are arranged between the baffle plate and the back plate and
  • the direction of deformation of the buckling plates is clearly specified. It is essential that the pre-deformations of the buckling plates point in the same direction, since this is the only way to ensure that the deformation of one buckling plate also affects the others
  • Buckling plates can be transferred and deformation of these other buckling plates is initiated.
  • the buckling plates are connected to one another by means of a pull-pressure means.
  • a push-pull means transmits both push and pull forces without itself
  • rod-shaped components that are sufficiently thick can be used, which do not buckle even under pressure.
  • the synchronization plate is parallel to the back plate and the baffle plate
  • At least one shear-resistant connecting plate (support plate) between the back plate and the baffle plate, which prevents parallel displacement of the baffle plate against the back plate.
  • This support plate is available as a
  • the arrangement of the support plate can be on the upper or lower
  • a preferred embodiment of the invention provides for two support plates, each one at the top and one at the bottom, so that the energy-absorbing device can be completely encased with additional lateral covers. Such is the energy dissipation device
  • the energy absorbing device according to the invention forms a substantially hollow, cuboid assembly, so that it is expedient in a further development of the invention to at least partially fill this cavity with further energy absorbing elements. This allows the

  • the rear energy-absorbing element extends between the synchronization plate and the back plate, but does not touch them, but has a certain distance from the back plate.
