Definitions

  • the invention relates to a buffer shock energy absorption device, in particular for urban rail vehicles, with a primary energy absorption device integrated in a central buffer coupling, the energy absorption device absorbing buffer forces occurring during driving and maneuvering operation, and a secondary energy absorption device, resulting from excessive impact impacts, the center buffer coupling being articulated a horizontally mounted coupling cross member which is displaceable in the longitudinal direction of the vehicle is fastened.
  • the middle buffer couplings usually used in city rail vehicles are usually equipped with an energy dissipation device, which is designed so that the buffer forces occurring during normal driving and maneuvering operations can be absorbed and absorbed without damage.
  • the object of the present invention was to develop a shock-absorbing and energy-absorbing device which is characterized on the one hand by the small space requirement and on the other hand by the functional advantages of the above-described ram bar construction, furthermore the parts of the rail vehicle underframe which are irreversibly deformed in the case of greatly excessive impact impacts are easily replaceable should be.
  • this object is achieved in that the clutch belt carrier is arranged in the vehicle head piece behind consoles pointing to the longitudinal center of the vehicle, fastened to the longitudinal ends of the outer longitudinal members of the rail vehicle, and in that projecting at the ends of the clutch cross member, projecting beyond the front end of the rail vehicle Shock elements arranged in the longitudinal direction of the vehicle are fastened, which are mounted in the guides of the consoles with the interposition of the secondary energy absorption device which is effective only after the travel of the primary energy absorption device has been exhausted.
  • the impact elements are detachably connected to the coupling carrier at their end facing the rail vehicle.
  • the secondary energy consuming device has mechanical, hydraulic or elastomeric working members.
  • the reversible primary shock absorption and energy dissipation device of the central buffer coupling is designed so that the stresses of normal shunting operation are sufficiently reduced, even with extremely unfavorable coupling operations.
  • the second energy consumption stage in the form of side buffer-like impact elements without spring travel is provided, which carry climbing protection devices at their free end. Only after the working capacity or the spring travel of the central buffer coupling with the primary energy-absorbing device has been exhausted, the climbing protection profiles of the secondary stage collide, the excess belching energy being converted into friction or deformation work after exceeding their response force.
  • the main advantages of the new shock attachment and energy dissipation device with a retractable clutch girder result from the elimination of a complicated lattice structure of the underframe for the coupling linkage, the elimination of the problematic predetermined breaking point in the coupling linkage and the elimination of the force interruption which is detrimental to the lightweight construction when addressing a predetermined breaking point.
  • Another advantage of the embodiment according to the invention is that inclined shocks can also be absorbed satisfactorily.
  • the coupling cross member is expediently connected to the abutment elements by means of expansion screws, the coupling cross member being centered on the brackets via conical centering devices.
  • the undercarriage of the rail vehicle has two outer long girders 2, which have brackets 4 pointing at their front ends to the center of the vehicle.
  • These brackets 4 are flat on their side facing the center of the vehicle and are provided with conical centering devices 5.
  • the essentially straight coupling cross member 1 is centered on the centering devices 5.
  • the coupling cross member 1 carries the central buffer coupling 6 with the primary energy dissipation device 7 in an articulated manner.
  • the brackets 4 carry the secondary energy dissipation device 10.
  • This secondary energy dissipation device 10 consists of those over the head end of the Rail vehicle projecting, side buffer-like shock elements 9 with frontal climbing protection devices 11 and mechanical supports 13 supported on the brackets 4, the shock elements 9, guided in guides 8 of the brackets 4, being non-positively connected to the coupling cross member 1 by means of the screws 12.
  • the energy absorption device 10, which acts mechanically in the exemplary embodiment, can also consist according to the invention of hydraulic or elastomeric working members.
  • the entire energy is absorbed in the primary energy dissipation device 7 of the central buffer coupling 6.
  • the secondary energy dissipation device 10 When exceeding the permissible The climbing protection devices 11 of the push elements 9 hit the obstacle or the climbing protection device 11 of another rail vehicle, the secondary energy dissipation device 10 then being activated by retracting the push element 9. The excess belching energy is then converted into friction or deformation work within the energy dissipation device 10. With the retraction of the push element 9, the bracing of the coupling cross member 1 with the brackets 4 is inevitably released.
  • the coupling cross member 1 can now be pushed back together with the central buffer coupling 6 either in a straight line with a central buffer joint or obliquely with an eccentric buffer joint until the belching energy in the energy dissipation device 10 on the brackets 4 is completely converted into friction or deformation work.
