Definitions

  • the invention relates to a device for compensating for that Energy absorption capacity of buffer elements of rail vehicles exceeding impact energy, consisting of one or more between the main frame of the rail vehicle and its buffer elements arranged energy consumption elements with box-like structure and square cross-sectional shape.
  • a device of this type is from the magazine ZEV + DET Glas.Ann.119 (1995) No. 9/10 September / October, pages 300 to 307, "The impact safety of railway vehicles"known in which the energy consumption elements of three arranged on the main frame of the rail vehicle box-like beams with a closed cross-section.
  • This one Carrier no significant stability against lateral forces have, in addition to the actually effective central support, the two other beams set at an angle as inclined supports, which are high Exercise support against lateral operating forces.
  • At a Impact only deforms the central beam through an axial one Folding. This wrinkle bulge that occurs in the manner of a bellows (Upset deformation) of the central beam goes with optimal Energy compensation.
  • the inclined supports fail due to their large angle of attack due to much less energy double buckling.
  • Their main function is mainly: Management function for the central carrier in order to ensure that it is energetically highly effective ensure axial folding.
  • the invention has for its object energy consumption elements to design the aforementioned type so that when using only a box-like carrier between the buffer element and the main frame increased stability against lateral forces and moments as well is given to eccentric longitudinal forces and that the carrier deformed in the event of an impact only by axial buckling of the folds.
  • this has the advantage that only a simple one Part between the buffer element and the main frame is to be provided and other that this component is only in the for optimal energy compensation suitable axial fold bulge deformed.
  • the order of side supports to prevent buckling of the there is no need for the carrier provided for the axial folding.
  • the invention is based on the knowledge that at one an impact triggered in the beam, this is initially in the Set the area of the buffer element in which the carrier the lower Has cross section. Because the resistance to deformation of the wearer progressively increased due to the increasing cross section to the main frame, arises an axially continuous from the buffer element to the main frame Wrinkle bulge, causing an uncontrollable buckling like this could occur with a beam with a constant cross-sectional shape, can be excluded.
  • the carrier has at least in the area the main frame is the shape of a rectangle with the longer sides are located horizontally.
  • the side support forces of the Increase energy consumption element are provided.
  • the structure of the carrier or energy consumption element in the area of the buffer element in defined areas with weak points e.g. in Form of notches in the wall of the carrier, may be provided.
  • weak points can be specified at which point and in what order the walls of the beam through parallel successive folds should deform.
  • the defined weakening of the structure of the carrier only in the front Area arranged or decrease to the rear area.
  • the buffer element is inside arranged of the box-like carrier and projects substantially above it only in the axial length of the suspension travel of the buffer element. This means that the overall length of the rail vehicle remains the same one the effective overall length of the functioning as an energy consumption element box-like carrier enlarged, on the other hand, the inner arrangement the buffer element in the deformation of the box-like carrier a self-centering, by which the danger of a lateral buckling of the wearer is further reduced.
  • the is between Buffer element and main frame arranged carrier designed as an inverted tube, in which the wearer is subjected to an impact load in the range of Buffer element in the manner of a rolling membrane inside and that Buffer element immersed in the interior of the carrier.
  • the cross section of the one designed as an inverted tube preferably takes closed beam tapered towards the main frame, thereby achieving that the energy-consuming inversion process in the area of the buffer element begins and then progressively increases the inversion resistance continues in the back.
  • the carrier 3 and 4 consist of a strong sheet metal and have a box-shaped structure with rectangular closed cross-sectional shape.
  • the cross section of the beams 3 and 4 takes back to the main frame 1 conical to and is on this with the cross-sectional shape as horizontal fixed rectangle.
  • the brackets 3 and 4 are on the main frame 1 releasably attached, likewise the buffer elements 5 and 6 are releasably attached the carriers 3 and 4 attached.
  • the carrier 3 and 4 with Connection plates must be provided.
  • Fig. 1 is an undeformed carrier 3 and on the left side a deformed support 4 is shown on the right-hand side.
  • the structural design of the beams 3 and 4 is largely ensured that the carriers 3 and 4 even with off-center introduction the impact energy does not buckle (bending deformation) but itself deform by axial buckling. This caused by compression Deformation causes a parallel folding 8 of the walls of the Carriers 3 and 4 in the manner of a bellows.
  • FIG. 3 shows another embodiment of the energy dissipation elements in the form of partially enclosing the buffer elements 15 and 16 Carriers 13 and 14.
  • the buffer elements 15 and 16 protrude above Carrier 13 and 14 only in a length that the spring travel of the buffer elements 15 and 16 corresponds to the normal operation of the rail vehicles. With the same External dimensions of the rail vehicle can thus be the most effective Length of the carrier 13 and 14 are increased.
  • the beams 13 and 14 compress energy-consuming axial wrinkle together.
  • 12 through openings 15 'and 16' be provided for the buffer elements 15 and 16.
  • FIG. 3 shows on the left side an undeformed carrier 13 and on the right side a deformed beam 14. It is only a partial deformation, since the buffer element 16 is not yet Passed through opening 16 '.
