Definitions

  • the invention relates to a collision protection device for rail vehicles, particular the ends of locomotives equipped with driver's cabs, Railcar, multiple units and control car is arranged and one in the underframe stem provided central buffer coupling with predetermined breaking points, a guide shaft and an underrun protection and energy absorption elements.
  • Such devices are quite generally of local rail vehicles and DE 36 32 578 A1, DE 19502217 A1 and DE 196 38 739 6 known. They usually consist of an automatic central buffer with reversible and irreversible absorbers in the coupling rod, a predetermined breaking connection at the attachment of the central buffer coupling, and in each case laterally in front of the head carrier attached absorbers.
  • the disadvantages of these devices are in particular in the insufficient impact compatibility in collisions with extraneous obstacles or with vehicles equipped with side buffers and in need of laterally arranged profile plates to use as Aufkletterstoffvorraumen whereby thereby the possibilities for shaping the vehicle head are severely limited.
  • the indicated in claim invention is based on the problem, with elimination the disadvantages of the prior art, a universally applicable collision protection device for rail vehicles, in particular for those with driver's cabs equipped ends of locomotives, railcars, multiple units and control cars which takes account of the real risks of accidents (compatibility), climbing up counteracts collisions with other rail vehicles and a variable Design of the vehicle head permits.
  • the proposed collision protection device consists of FIGS. 1 and 2 a central buffer coupling 1, which at a predetermined breaking point 2 on the head support 3 of the base frame 4 is attached, from energy absorbing elements 5, each side of the central buffer coupling 1 between the lower edge of the head carrier 3 and the Rammschutzkonstrutation 6 extensively supported on the base frame 4, from at least one, the deflection of the central buffer coupling 1 limiting vertical stop 7, which is supported on the energy absorption elements 5, from an underrun protection 8, which in operative connection with the head support 3 and the Rammschutzkonstrutation 6 stands as well as from a guide shaft 9, the unhindered Retreating the central buffer coupling 1 after the failure of the predetermined breaking point. 2 allows.
  • the known middle buffer coupling 1 in the embodiment allows coupling speeds according to the operational requirements of the operator (first Speed level). In the event of overshoots (exceeding the permissible coupling speed), e.g. In shunting accidents, the damage remains up to a higher Impingement speed (second speed level) on a compression tube in the coupling beam and an easily replaceable part of the headliner 10 at the vehicle end limited. Are the strokes of the central buffer coupling at even higher collision speeds 1 exhausted, this deviates after the response of the predetermined breaking point. 2 in a conventional manner in the guide shaft 9 of the base frame 4 back.
  • the energy absorption elements 5 come with the Kollisionskontrahenten in Contact and are plastically compressed.
  • the energy absorption elements 5 extend in the vertical direction approximately from the lower edge of the head carrier 3 to the upper edge of the Rammschutzkonstrutation 6. This arrangement ensures a good protective effect in collisions with similar vehicles or larger extraneous obstacles.
  • the energy absorption elements 5 come in these cases in a conventional manner only after the failure of the predetermined breaking point 2 and the retreat of the central buffer coupling 1 in the guide shaft 9 to the effect.
  • the breaking force F B of the predetermined breaking point 2 and the total deformation resistance F 1 + F 2 of the energy absorption elements 5 are dimensioned such that the force F wk which can be borne by the wagon body is not exceeded (F B ⁇ F Wk and F 1 + F 2 ⁇ F Wk ) ,
  • the climbing is avoided by the large contact area at the front of the energy absorbing elements 5, their defined resistance to deformation and the small vertical difference between the vehicle's center of gravity (inertial force) and the impact force of the impact force.
  • the arrangement of the central buffer coupling 1 and the energy absorption elements 5 designed for collisions with similar vehicles and extraneous obstacles has, in the case of collision with vehicles equipped with side buffers, the consequence that parallel effects of central buffer coupling 1 and energy absorption elements 5 can occur. There is a risk of overloading the body structure.
  • This disadvantage is overcome here by the energy absorption elements 5 are arranged so that they deform when colliding with side buffer vehicles predominantly locally in the region of the penetrating buffer, wherein the resistance force F 1 of the energy absorption elements 5 in the local deformation and the breaking force F B of the predetermined breaking point 2 at the central buffer coupling 1 are dimensioned such that the force which can be borne by the car body is not exceeded (FIG.
  • an underride guard 8 is arranged in operative connection with the head carrier 3 and the ram protection structure 6 below the head carrier 3 or the energy absorption elements 5. The front edge of the underrun protection 8 is set back from the front edge of the energy absorption elements 5 by the amount of the intended compression length S of the energy absorption elements 5, so that a parallel action of the energy absorption elements 5 and the underrun protection 8 is excluded.
  • central buffer coupling 1 and energy absorbing elements 5 before the actual supporting vehicle frame allows a limitation of Vehicle damage to these components and to the front parts of the head fairing 10 up to a defined collision speed (third speed level).
