Definitions

  • the invention relates to a wheelset guide of a bogie with the features of the preamble of claim 1.
  • a pair of coil springs is assigned to a bearing housing of a wheel set, on the upper end of which the bogie frame is seated and the lower end of which is supported by a rubber element on a base plate which is firmly connected to the bearing housing.
  • the helical spring and the rubber element are connected in series in terms of effectiveness, the emergency guide pin for transverse forces and thus for the guide only becoming effective when the radial play in the rubber element has been overcome.
  • the rubber element is made entirely of solid rubber and has the same spring characteristics in all directional loading directions.
  • a wheel set guide of a bogie is also known (EP-A 0 421 864), in which a pair of helical springs is also assigned to a bearing housing of a wheel set, the helical springs being supported on the one hand on the bogie frame and on the other hand on a base plate connected to the bearing housing.
  • a rubber element is additionally attached to the base plate, which engages concentrically in the respective coil spring and concentrically surrounds the emergency guide pin provided therein, and is attached to it without play.
  • the rubber element consists of concentric mutually arranged rubber ring elements, an air chamber being formed in each of these rubber ring elements. The air chambers are formed axially from both ends in the rubber ring elements in question and lie in a common diameter plane. As a result, the rubber element has different suspension characteristics in the radial direction.
  • the invention has for its object to take measures in a wheel set guidance of a bogie according to the preamble of claim 1, by means of which the self-adjustment of wheel sets during sheet travel is supported.
  • an angularly offset arrangement of air chambers in the rubber element achieves a radial force-dependent radial setting of the wheel sets when traveling on bends after the twisted setting of the air chambers in the rubber elements cause vector forces which support the self-setting of the wheel sets.
  • the rubber element is preferably designed as a pretensioned, concentrically constructed cone element, the prestressing of which is achieved by the weight of the vehicle and the conicity angle is selected such that tensile stresses do not occur in the rubber element in any operating state.
  • the rubber element is mounted in particular below the primary suspension or, for example, in a cavity in the wheelset bearing housing and connected to a downward emergency guide pin of the bogie frame.
  • the angular position of the rubber element is advantageously fixed via a groove in its outer ring and a screwable pin in a cavity of the wheelset bearing housing and in the cavity there are several threaded holes arranged at different heights, each with a different angular position, and allow easy subsequent adjustment to changing operating conditions.
  • the air chambers are in particular rotated by an angle between 5 ° and 60 ° to the longitudinal axis of the bogie in order to be able to bring about the vector forces mentioned when traveling through bends.
  • FIG. 1 shows a bogie 1 with bogie frame 2, wheel disc 3, wheelset bearing 4 and wheelset bearing housing 5.
  • Coil springs 6 are arranged as primary suspension between the wheelset bearing housing 5 and the bogie frame 2.
  • the coil springs 6 are supported on the wheelset bearing housing 5 on base plates 11.
  • conical mega springs (rubber-metal springs) 7 are firmly mounted.
  • the mega springs 7 have central pins 9 which protrude upwards through holes in the base plates 11 and are connected in a rotationally fixed manner to emergency guide pins 8 of the bogie frame 2 which are directed downward within the coil springs 6.
  • the mega springs 7 are shown cut half offset by 90 °, so that partly the full rubber material and partly air chambers 10 can be seen.
  • the mega springs 7 are arranged as shown in FIGS. 2 and 3.
  • the air chambers 10 of the mega springs 7 are arranged symmetrically at the front and rear in the direction of travel, so that there is a softer characteristic in this direction than in the lateral region.
  • the air chambers 10 are inserted rotated inwards to the direction of travel by an angle between 5 ° and 60 ° to the longitudinal axis of the bogie.
  • centrifugal forces F 1 or F 2 act on the bogie frame and are transmitted together via the primary suspension and the mega springs 7 to the wheelset.
  • the twisted setting of the air chambers of the Megi springs gives a characteristic that results in vector forces V 1 or V 2 , which supports the self-adjustment of the wheel sets.

Claims (7)

  1. Guidage d'essieu monté d'un bogie (1), constitué d'un ressort hélicoïdal (6) ou d'une suspension primaire, disposé à titre individuel ou par paire contre un logement de palier (5) d'un essieu monté, ainsi que d'un élément en caoutchouc (7), disposé à titre individuel ou par paire, où le guidage de l'essieu monté s'effectue simultanément sous l'effet Flexicoil du ou des ressorts hélicoïdaux (6) ainsi que de la rigidité radiale de l'élément en caoutchouc (7), et l'élément en caoutchouc (7) comporte des différences au niveau des caractéristiques longitudinales et transversales du guidage, grâce à la constitution de chambres d'air (10) disposées localement, caractérisé en ce que, grâce à la disposition des chambres d'air (10) dans l'élément en caoutchouc (7), selon un angle calculé au préalable, on arrive à une orientation radiale de l'essieu monté qui dépend de la force centrifuge.
  2. Guidage d'essieu monté d'un bogie selon la revendication 1, caractérisé en ce que l'élément en caoutchouc (7) est réalisé sous forme d'un élément conique précontraint, de structure concentrique.
  3. Guidage d'essieu monté d'un bogie selon la revendication 2, caractérisé en ce que la précontrainte de compression de l'élément en caoutchouc (7) est réalisée par le poids propre du véhicule, et que l'angle de conicité est choisi de façon que des contraintes de traction n'apparaissent dans l'élément en caoutchouc (7) dans aucun état de marche.
  4. Guidage d'essieu monté d'un bogie selon l'une des revendications précédentes, caractérisé en ce que l'élément en caoutchouc est, en-dessous de la suspension primaire, logé sur ou dans le logement de palier (5) de l'essieu monté (par exemple dans une cavité (12), et est relié à un tourillon de guidage d'urgence (8), dirigé vers le bas, du châssis de bogie (2).
