Definitions

  • the invention relates to a supply connection for a wheel steering device for a running gear for a rail vehicle, which has at least a first supply line, at least a first connecting part, a feed part and a longitudinal axis of the supply connection, the at least first supply line being routed in the feed part and having a Supply unit and can be connected to a first fluid chamber of a first elastic element for wheel angle position.
  • Bogies for rail vehicles must have a high level of driving safety. This can be improved, for example, by arranging a wheel or wheelset steering device. A targeted positioning of wheels or wheelsets by actively rotating them about their vertical axes is provided in a known manner to prevent unstable driving conditions.
  • a wheel or wheel set steering device allows a reduction in wear on wheels and rails.
  • Wheel and wheel set steering devices often have active elastic bearings, which are designed as hydraulic bushes, for example.
  • the EP 0 870 664 B1 a method and a device for wheel set guidance of rail vehicles.
  • a device is shown as an example in which the setting angles of wheel sets are generated by a two-chamber fluid bushing.
  • a swing arm connects a wheelset to a chassis frame.
  • the fluid bushing is located between the swing arm and the landing gear frame.
  • Their fluid chambers are connected via corresponding connections alternately applied with fluid, whereby a relative movement between the swing arm and the chassis frame is generated.
  • EP 1 457 706 B1 discloses a hydraulic bushing which is arranged in an axle guide of a running gear of a rail vehicle.
  • the hydraulic socket has at least two fluid chambers filled with hydraulic fluid, which are connected to one another via an overflow channel to achieve fail-safety.
  • the overflow channel is designed as a passive vibration absorber.
  • WO 2018/095961 A1 describes a wheel control arrangement for a chassis of a rail vehicle, in which an elastic bearing which adjusts a steering angle of a wheel set and has two fluid chambers is connected to a hydraulic supply.
  • the hydraulic supply has a closed hydraulic circuit.
  • the invention is based on the object of specifying a structurally integrable supply connection which is further developed than the prior art and which can also be used with a limited space budget.
  • this object is achieved with a supply connection according to claim 1, in which the at least first connecting part is T-shaped, is connected to the feed part via a first leg of the at least first connecting part and at least one first connecting part is connected to a second leg of the at least first connecting part Landing surface for connecting the at least first connecting part to a wheel steering component or a chassis component.
  • the supply connection according to the invention is therefore compact and robust. On the one hand, it can be fluidly connected to a supply unit and to a first fluid chamber, but on the other hand it can also be connected to a wheel steering component or a chassis component (e.g. to a swing arm of a wheelset guide device, to a wheelset bearing housing or to a chassis frame, etc.).
  • the supply connection according to the invention therefore fulfills both fluidic (e.g. hydraulic) functions and connection-technical-structural functions.
  • the first supply line is routed in the feed part, the first supply line is shielded from environmental influences.
  • the first connecting part is designed in a T-shape, as a result of which legs of the first connecting part act as defined assembly areas. This enables simple and reliable assembly and disassembly of the first connecting part.

  • the feed part can be short in the direction of the longitudinal axis of the supply connection or an extension of the feed part in the direction of the longitudinal axis of the supply connection can be avoided by the first connecting part.
  • a preferred solution is achieved if a first coupling part of a fluidic first sealing coupling is arranged in the supply part, by means of which the at least first supply line can be separated.
  • This measure enables rapid coupling or rapid decoupling of the feed part (e.g. to or from a supply unit).
  • a mechanically and fluidically secure connection is achieved. Unintentional loosening of the feeding part is avoided. The connection is tight, and unintentional escape of fluid, for example in the area of a parting line of the feed part, is avoided. If, for example, valves are provided in the first closure coupling, a defined pressure level can be maintained in the supply part even after the first supply line has been separated.
