  • the elastomeric material of the spring elements deformed into the through holes 42.
  • the burrs of the holes 42 get caught in the elastomeric elements and thus effectively prevent twisting of the elastomeric members against each other.
  • a schematic sectional view of a linkage 1 with corresponding cams on the front spring plate 12, an intermediate plate 41 and serving as a pressure plate spring plate with a pronounced or enhanced wave contour is the schematic sectional view of FIG. 8 to remove.
  • the base plate 10 is provided with a spring element receptacle, ie with a matched to the outer contour of the spring element recording.

  • Both serving as a pressure plate spring plate, which is attached to the coupling rod, as well as a spring element receiving the base plate on the Wagenbox connection are - as the exemplary embodiment according to, for example, FIG. 3 - equipped with a wavy shape on the surface.
  • a spring element is positioned and biased between the two surfaces. By a relatively high biasing force, it is possible that the spring element conforms to the two surfaces.
  • the two wave surfaces are arranged so that a wave crest also on one side with a wave trough on the coincides with the other side, so that the entire elastomeric spring element is forced into a wavy shape and thus there is no possibility that it can rotate against the coupling rod or the connection to the car body.
  • the coupling rod against the Wagenkastenanbin- is secured against rotation.
  • an anti-rotation is provided in an easy to implement yet effective manner, eliminating the need for anti-rotation or recovery of the twisted Coupling rod 2 to provide in their starting position Abstützept etc. in the form of, for example, a complicated leg spring assembly.
  • a positive engagement of the front spring element 20 and the base plate 10 or the front spring plate 12 takes place.
  • the rear spring element 30 and the rear end element 30 facing the rear end face of the base plate 10 in such a way that a positive interlocking becomes possible between these two components.
  • the rear spring plate 14 such that it forms a positive engagement with the rear spring element 30. Since the solution according to the invention makes it possible to form at least the wagenkastenseiti- end region 3 of the coupling rod 2 with a circular cross-sectional shape, can be added to the passage opening 11 of the base plate 10 is a spherical bearing to support the coupling rod 2 in the passage opening 11 of the base plate 10 and to allow a movement of the coupling rod 2 relative to the base plate 10 with the least possible material wear.
  • the invention is not limited to the exemplary embodiment described with reference to the figures, but also possible in a plurality of variants.

Abstract

L'invention concerne une articulation (1) pour la liaison articulée d'une barre d'attelage (2) avec une caisse de wagon, ladite articulation (1) présentant une plaque de base (10) pouvant être reliée à une caisse de wagon. L'articulation présente également un dispositif de choc/traction (9) doté d'une coupelle de ressort avant (12) et d'une coupelle de ressort arrière (14). Selon l'invention, le dispositif de choc/traction (9) présente au moins un élément élastique avant (20) en matière élastique, disposé entre la plaque de base (10) et la coupelle de ressort avant (12) et au moins un élément élastique arrière (30) en matière plastique élastique, disposé entre la plaque de base (10) et la coupelle de ressort arrière (14), l'élément élastique avant (20) et ledit au moins un élément élastique arrière (30) se présentant sous forme d'anneau ou de tore, à l'état non comprimé. Selon l'invention, il est notamment prévu que la coupelle de ressort avant (12) présente une face frontale profilée au moins par endroits qui fait face à l'élément élastique avant (20) et que la plaque de base (10) présente une face frontale profilée au moins par endroits qui fait face à l'élément élastique avant (20), le contour de la face frontale de la coupelle de ressort avant (12) est complémentaire au moins par endroits du contour de la face frontale de la plaque de base.
