Definitions

  • the invention relates to a bogie according to the preamble of the first claim.
  • the invention has for its object to take measures in a rail vehicle bogie having at least two axes according to the preamble of the first claim, by means of which a three-point bearing can be realized in a simple manner.
  • the desired three-point bearing is achieved by the simultaneous use of separate spring elements and interconnected spring elements, which increases safety against derailment, since no more differences can occur in the wheel contact forces on the (theoretically) centrally mounted wheel pair.
  • a common gas storage for the two interconnected spring elements is connected to the connecting line.
  • the interconnected spring elements can be provided with damping in the form of a throttle at the transition to the connected line, while the separate spring elements can be provided with damping in the form of a throttle directly on the piston.
  • the gas volume can be arranged in the spring elements, or gas stores as external elements are connected to the spring elements, part of the liquid volume and the gas volume being arranged in the gas stores. If the spring elements are provided with gas and oil fillings, the height of the spring elements can be regulated, for example, by refilling or draining the liquid.
  • the spring elements 1, 3 of a bogie are shown here, the upper spring elements 1 being arranged on one bogie side (longitudinally) and the lower spring elements 3 being arranged on the other bogie side.
  • All spring elements 1, 3 consist of a cylinder 2 and a piston 8 guided therein and act on a hydropneumatic basis. While the upper spring elements 1 are connected to one another via a connecting line 15 and a common gas reservoir 12 is connected to this connecting line 15, the gas reservoir 11 is integrated into the lower, separately arranged spring elements 3. Accordingly, the damping valves 9, 10 are different, namely in the case of the connected spring elements 1 at the transition to the connecting line and in the separate spring elements 3 on the piston.
  • the separate spring elements 3 have a gas and oil filling 5, while the connected spring elements 1 have separate gas and oil fillings 6, 7. All spring elements 1, 3 have vents 4.

Claims (8)

  1. Bogie pour véhicules à moteur, avec une suspension primaire affectée à des roues, suspension réalisée avec des éléments élastiques hydropneumatiques (1, 3), comportant un cylindre (2) et un piston (8), avec des volumes de liquide et des volumes de gaz correspondants, auquel cas au moins une partie (13) du volume liquide est disposée dans les éléments élastiques (1, 3), caractérisé en ce qu'on prévoit au moins deux essieux pour les essieux montés ou les paires de roues folles, et que d'une part les deux éléments élastiques (1) d'un essieu monté ou d'une paire de roues folles, ou les éléments élastiques (1) d'un côté du bogie, sont interconnectés par l'intermédiaire d'une conduite (15), et d'autre part que les autres éléments élastiques (3) sont montés séparément.
  2. Bogie selon la revendication 1, caractérisé en ce que les éléments élastiques interconnectés (1) sont pourvus d'un amortisseur sous forme d'un étranglement (9) au niveau de la transition avec la conduite raccordée (15).
  3. Bogie selon la revendication 1 ou 2, caractérisé en ce que les éléments élastiques distincts (3) sont pourvus d'un amortisseur sous forme d'un étranglement (10) au niveau du piston (8).
  4. Bogie selon la revendication 1 ou 3, caractérisé en ce que le volume de gaz (11) est disposé dans les éléments élastiques distincts (3).
  5. Bogie selon la revendication 1 ou l'une des suivantes, caractérisé en ce que des réservoirs de gaz (12) sont raccordés, sous forme d'éléments externes, aux éléments élastiques interconnectés (1), auquel cas une partie du volume liquide et le volume de gaz sont disposés dans les réservoirs de gaz (12).
  6. Bogie selon la revendication 1 ou 2, caractérisé en ce qu'un réservoir de gaz commun (12) pour les deux éléments élastiques interconnectés (1) est raccordé à la conduite de liaison (15).
  7. Bogie selon la revendication 1 ou l'une des suivantes, caractérisé en ce que les éléments élastiques distincts (3) comportent un orifice de remplissage de gaz et d'huile (5).
  8. Bogie selon la revendication 1 ou l'une des suivantes, caractérisé en ce que les éléments élastiques interconnectés (1) comportent des éléments de remplissage de gaz et d'huile (6, 7) distincts.
