  • the traverse unit forms a chamber device adapted to form an air reservoir receiving pressurized air.
  • the present invention further relates to a rail vehicle comprising such a running gear.
  • Modern rail vehicles in particular, high speed rail vehicles, typically use such running gears which have to meet a variety of different, partially contradictory requirements to meet the goal of providing good riding comfort at high speeds while consuming as few energy and building space as possible.

  • you to the increasing number of components to be arranged in a modern running gear comparatively few building space is available within the running gear strictly limiting the size of the air spring and, hence, the amount of air to be received within the air spring.
  • a further problem to be solved when using pneumatic components in a running gear is the fact that an air reservoir of sufficient size has to be provided in the region of the running gear to allow rapid air supply to the respective pneumatic component.
  • the problem arises that comparatively limited building space is available for arranging such an air reservoir within the running gear.
  • DE 195 44 030 A1 discloses a running gear wherein the traverse unit forms an air reservoir for a pneumatic brake system of the running gear.
  • this configuration has the disadvantage that flexible piping has to be provided compensating for relative motion between the traverse unit and the pneumatic brake units of the pneumatic brake system.
  • a generic running gear is known, for example, from US 4,817,536 , US 4,278,030 and US 2,908,230 each disclosing a configuration with a separate chamber unit for each air spring. Such a configuration requires comparatively fast reacting pressurized air supply to the individual air springs.
