Definitions

  • the invention relates to a device for limiting a pitching movement between a bogie of a rail vehicle and a supported on the bogie car body with a fastened to the bogie or to the car body stop and a fastened to the car body or on the bogie counter-stop, the stop a the counter-stop facing stop surface is formed, which gets in contact with the counter-stop during operation of the device.
  • the object of the invention is to provide a device of the type mentioned, with which the usable space of a rail vehicle can be increased.
  • the invention solves this problem by a device having the features of claim 1.
  • a circular arc-dependent pitch stop is provided.
  • the device according to the invention consists of a transversely to the direction of travel on the car body or on the landing gear to be mounted counter-attack with a ramp in this transverse direction stop contour, which can also be referred to as a backdrop.
  • the designated as a stop counterpart is attached to the respective other component of the rail vehicle, ie on the bogie or on the car body, and gets in a correspondingly large pitching movement in contact with the counter-stop.
  • a Fahra rotation of the car body relative to the bogies which occurs regularly when cornering, stop and counter-attack in a horizontal direction at right angles to the direction of travel, ie in the Y direction, offset from each other.
  • the maximum possible pitching motion is dependent on the degree of offset and thus on the degree of boring.
  • the scenery of the counter-attack is designed so that the maximum pitching movement is the smaller, the greater the rotation of the car body relative to the respective bogie.
  • the counter-attack is attached to the car body.
  • the stop is mounted on the bogie so as to effectively limit a pitching motion.
  • multiple stops and counter-stops can be provided. Due to the limitation of the relative vertical movement between the bogie and car body depending on the transverse offset, ie the traveled horizontal arc, less space is free to allow the pitching movement. This has an enlargement of the installation spaces in the wake, which can then be used for other purposes. In addition, there is also a cost reduction in terms of maintenance of the rail vehicle, since only limited bogie movements and impact forces arise.
  • the counter-stop is designed mirror-symmetrically in the side view. The mirror-symmetrical design provides the same circular arc-dependent limitation in right and left turns.
  • the abutment is rib-shaped in a cross-sectional view, wherein the abutment surface is formed on the rib tip, which faces the counter-stop during operation.
  • the rib-shaped stop consists for example of a bent sheet metal.
  • the stop and the counter-stop are fastened to the rail vehicle by means of screw connections, for example.
  • the stop has a wear plate which covers at least the abutment surface.
  • the formation of the attack as a simple emergency stop in the form of a rib is particularly cost.
  • the stop surface prevents too rapid wear of the stop, so that the replacement intervals are extended.
  • the stop on a spring With a reversible deformable spring is a particularly gentle power and even longer replacement intervals are provided.
  • the spring allows the setting of a defined force-displacement curve.
  • the stopper according to the invention has a reversibly deformable energy dissipation element.
  • the use of an energy dissipation element allows, in particular in combination with a spring, a defined limitation of the impact forces to an admissibly defined maximum.
  • the stop has an end stop for limiting a spring or Verformweges.
  • the pitching motion is permitted, for example, until a spring and / or an irreversible energy dissipation element are maximally compressed or deformed. Only then is a further pitching motion made impossible by a hard stop between the car body and bogie.
  • a force limit is provided against excessive overuse of the vehicle structure, since the forces are recorded in front of the hard stop controlled by spring and / or energy dissipation element.
  • the invention also relates to a rail vehicle with bogies and at least one car body, wherein between each bogie and each car body, a device according to the preceding kind is mounted.
  • FIG. 1 shows an embodiment of the rail vehicle 1 according to the invention in a side view.
  • the rail vehicle 1 has a car body 2 and two bogies 3, each having two wheelsets 4, each with two wheels, which are guided by rails 5.
  • the number of wheelsets per bogie is not essential to the invention.
  • a bogie frame 6 is supported via first spring means 7.
  • the car body 2 is supported via second spring means 8 on the bogie frame 6.
  • FIG. 3 shows a front view of a no longer claimed embodiment of the rail vehicle 1 and the device 12, which has a stop 13 and a counter-stop 14.
  • the counter-stop 14 is mounted transversely to the direction of travel X to the car body 2 and extends In the direction of Y. He has a respect to the Z-axis mirror-symmetrical backdrop-shaped contour, so that with a displacement of the car body 2 with respect to the bogie 3 in the Y direction, the distance DZ between stop 13 and counter-stop 14 and thus the maximum possible Nick movement reduced.
  • the maximum pitching movement is due to the backdrop-shaped configuration of the counter-stop of the circular arc of the curve, which passes through the rail vehicle. This dependence of the pitch stop on the transverse offset between car body 2 and bogie 3 in the Y direction is described by f (y).
  • the stop 13 is in the form of a rib, wherein on the counter-stop 14 facing the tip of the rib, a stop surface is formed, with which the stop 13 comes into contact with the rib 14.
  • the stop 13 consists of a metal sheet, wherein the sheet metal material is, for example, stainless steel.
  • FIG. 4 shows the no longer claimed embodiment according to FIG. 3 ,
  • the stop 13 has a stop roller 15, with which the stop 13 is controlled on the backdrop-shaped outer contour of the counter-stop 14 and rolls with defined forces. Due to this configuration, an even more gentle force absorption is possible.
  • FIG. 5 shows the embodiment according to FIG. 1 However, wherein the stop 13 has a spring 16 and an irreversible force element 17.
  • the irreversible force element 17 is rib-shaped and mounted on a U-profile 18, between the free legs, the spring 16 extends.
  • the device 12 has a defined Force-displacement curve so long until the spring 16 is completely compressed and the U-profile 18 his free legs in contact with the support frame 6 device.
  • the irreversible energy dissipation element 17 is irreversibly deformed, wherein the kinetic energy of the car body 2 is recorded by the energy absorbing element 17 controlled by deformation. In this way, the body and bogie frame structure is effectively protected against accidental deformation and damage.
  • FIG. 6 shows a no longer claimed further embodiment according to FIG. 5 , wherein the stop 13 instead of the energy dissipation element 17 has a stop roller 15.
