Definitions

  • the invention relates to anti-rotation elements on drives of tilting technology vehicles on railways.
  • Railway wagons usually exist. consisting of a car body and two drives equipped with wheelsets that are articulated to the car body.
  • the articulated mounting of the drives on the car body calls for a high level of driving comfort.
  • the body should remain as free from vibrations as possible and have a high level of suspension comfort.
  • stable running behavior of the drives i. H. no rolling movements can be achieved.
  • anti-rotation elements are used for this purpose, which act on the one hand on the car body and on the other hand on the chassis frame.
  • damping elements usually consist of hydraulic vibration dampers, which are articulated to the brackets of the corresponding points of attack.
  • Tilting technology vehicles are used on routes with a lot of arches, in which the car body leans into the curve like motorcyclists. As a result, a partial compensation of the centrifugal force caused by the bow travel and thus an increase in driving comfort for travelers is achieved in the interior of the tilting technology vehicle.
  • the anti-rotation element of a tilting technology vehicle is now elongated or compressed on the one hand by the rotation of the running gear on the curved curve and on the other hand also elongated or compressed by the inclination of the car body in the curve.
  • an anti-rotation element is attached between the running gear and the body of the vehicle in such a way that the anti-rotation element is elongated in a right-hand curve, for example, and is additionally lengthened by the inclination of the body.
  • the anti-rotation element must therefore perform a large quasi-static movement. This quasi-static movement superimposes the actual dynamic movement of the anti-rotation element, which leads to the damping effect.
  • the undercarriage experiences an additional moment directed towards the outside of the curve, which means that the lateral forces are already subjected to greater stress. said outer wheel of the leading wheelset to be further increased.
  • the car body experiences a moment that works against the drives of the tilting technology.
  • the advantage of the method according to the invention is that, when traveling through a bend, a rotational movement of the drive, depending on the direction of the bend, elongates or compresses the rotation-inhibiting element and
  • Claims 2 and 3 contain advantageous exemplary embodiments of the solution according to the invention from claim 1.
  • Fig. 1 schematically shows a car body of a tilting technical train with two bogies and the coupling of the anti-rotation elements according to the invention when traveling through a bend
  • Fig. 2 shows schematically a car body of a tilting train with two bogies and coupling of the anti-rotation elements according to the prior art when traveling through a bow
  • Fig. 2b left bow.
  • the anti-rotation element 6 is elongated, for example, in a right-hand bend (FIG. 2a), since the undercarriage 3 has to turn clockwise in the direction 2 in order to follow the bend and at the same time the car body 1 in the direction 9 to be inclined towards the inside of the arch.
  • This elongation generates internal forces in the anti-rotation element 7, which cause the undercarriage 2 to be turned towards the outside of the arch and the inclination of the car body 1 is impeded.
  • the chassis-side connection 5 of the anti-rotation element 6 must also be lower or at most the same height as the wagon body-side 4 even with the maximum inclination of the car body 1. Because if the chassis-side connection 5 of the anti-rotation element 6 were above the wagon-body side 4, the same disadvantageous effect would result as in the state of the art Technology.

Abstract

L'invention concerne un système d'éléments antirotation placés sur des organes de roulement de véhicules ferroviaires pendulaires. Selon l'invention, l'élément antirotation est fixé, par un de ses joints de fixation, à un organe de roulement sur le côté de celui-ci tourné vers le centre de la caisse dans le sens longitudinal et, par son autre joint de fixation, à la caisse sur le côté de celle-ci tourné vers l'extrémité la plus proche de la caisse, la fixation à la caisse étant toujours située à une hauteur supérieure ou égale à celle de la fixation à l'organe de roulement, y compris en cas d'inclinaison maximale de la caisse. Grâce à ce système, lorsque le véhicule se déplace dans une courbe, une rotation de l'organe de roulement entraîne une extension ou une compression de l'élément antirotation en fonction du sens de la courbe, tandis qu'une inclinaison simultanée de la caisse vers l'intérieur de la courbe entraîne une compression ou une extension de l'élément antirotation en fonction du sens de la courbe de sorte que, dans l'ensemble, l'élément antirotation subit une extension ou une compression nulle ou quasi nulle. L'élément antirotation peut ainsi fonctionner constamment à son point de fonctionnement optimal.
