Definitions

  • the invention relates to a device for preventing the mutual vertical sliding of the front surfaces (climbing) equipped with side buffers rail vehicles in frontal collisions, the spring apparatus of the side buffer at the forces occurring in normal operation at most allows a stroke in which the Aufkletter-protection device is not used comes.
  • rail vehicles are generally designed for the formation of longer train assemblies and thus for the transmission of the resulting high longitudinal forces, they have in the height range of train and shock devices reinforced bases.
  • a base unit combines a large part of the strength of the vehicle structure in itself.
  • a head-on collision if such a vertical offset of the undercarriages occurs that they can slide over each other (climbing or over-buffering), only the often much less load-bearing structures of the vehicles are available for reducing the collision energy, thus drastically worsening the consequences of the accident.
  • baffles are often located in the nominal position for side buffers to prevent damage from occasional contact with side buffers. Therefore, common practice is to realize the anti-climb protection simply in connection with the above-described clutch characteristic by arranging ribs on the baffles. Disadvantage of most running devices is that they can produce positive fit only in collision with similarly equipped vehicles, but not with normal side buffers with a smooth surface, which is also still lubricated. An advancement that eliminates this disadvantage has been successfully tested in the EU-funded BRITE-EURAM research project "Safetrain".
  • the ribbed baffle plate has been increased in height so that it projects above and below the impinging buffer plate and is pressed through it in the middle so that the ribs may include the edge of the buffer plate form-fitting manner.
  • a device which prevents the climbing of rail vehicles as a result of an accidental impact.
  • one of the front bumper of the rail vehicle is mounted above one of the side bumper of the rail vehicle on the underframe, which has a lower horizontal surface.
  • the safety gear is located at a height above the top edge of the buffer plate, which corresponds to the maximum allowable height offset of the side buffers of coupled vehicles.
  • the full buffer stroke is not hindered at the maximum permissible height offset of the vehicles in all operationally relevant 9.
  • a occurring at full indentation of the page buffer height offset of the side buffer is limited by reaching the maximum allowable height offset characterized in that the lower horizontal surface of the catcher rests against the upper edge of the buffer plate of the opposite vehicle and thus positively prevents further erection of the upstanding vehicle relative to the opposite vehicle.
  • the catch blocks penetrate each in the opposite region of the front wall of the opposing vehicle.
  • This object is achieved in that a combination of ribs with a ribbed plate surround the side buffers from above and below, the side buffers are pressed at defined limited force level at least up to the approach surface of the ribs, and limiting the buffer stroke by a division of the entire stroke is realized on several elements connected in series, with only those elements move in the operational forces, the strokes in the sum do not exceed the allowable value.
  • the fin plate 3, on which the ribs 2 are arranged, is horizontally divided so that the side buffer 1 can dip between the upper part and the lower part of the fin plate 3.
  • suitable reversible and possibly also irreversible energy absorbing elements can be ensured that initially the plate of the buffer 1 can push back so far that it is in a plane with the approach surface of the ribs 2 is (Fig. 5).
  • similarly equipped vehicles or those with a continuous ribbed plate at the same position so the vertical force is transmitted to prevent the Aufklettems on the engagement of the ribs 2.
  • Normal side buffers of vehicles without the climbing protection device according to the invention can dip after the engagement of the buffer plate 1 in the climbing protection device between the ribs 2.
  • Fig. 4 shows the position at the end of the operational stroke, in which the ribbed plates 3 are still behind the front surface of the buffer plate.
  • Fig. 5 shows the fully pushed back behind the rib plate 3 buffer plates.
  • an additional ribbed plate 7 can be arranged laterally of the buffering plate.
  • climbing protection devices are usually used in the context of a further crashworthy design of the vehicle and the possible energy absorption is limited by the relatively low strokes within the device described, a combination with a downstream crumple zone is favorable. This can either be part of the car body or - as shown - be formed together with the buffer and the climbing protection device as a superior, easily replaceable unit 6 for energy consumption.
