Definitions

  • the invention relates to a coupling device for a rail vehicle according to the preamble of claim 1.
  • Coupling devices of this type are known to be used for the coupling of rail vehicles in passenger or freight trains, such as those in the document EP-A-2 322 403 is explained. They basically consist of two coupling halves, which are arranged in each case a rail vehicle and can be coupled together. They are each provided with a coupling head and a pulling device for transmitting the tensile and impact forces on the vehicle body.
  • a provided in at least one coupling safety device absorbs the impact energy by converting the same into deformation energy within certain limits.
  • This deformation energy is generated in such a way that a cooperating with the pipe piece support of the coupling has a larger diameter than the inner diameter of the pipe piece and thereby expands this and deformed accordingly when pressed in a collision in the pipe section.
  • the invention has for its object to avoid these disadvantages and to provide a coupling device of the type mentioned, the passive safety device is effective in a crash as uniformly as possible over a long deformation distance.
  • the invention provides in this sense that the pipe section is preferably primed with a base color and the support with a sliding ring made of sliding material, preferably nodular cast iron (gray cast iron). In this way it is possible to manufacture the slide ring bearing support body from the most suitable material for its function.
  • a sliding ring made of sliding material, preferably nodular cast iron (gray cast iron).
  • the pipe section is made of a one-piece tube, which has continuously provided for in its deformation range inner diameter.
  • the invention further provides that the tube end provided with the pipe extension protrudes into an annular gap between the coupling flange and the support and there on the coupling flange inside or outside with a detachable connection as preferably a screw or bayonet connection can be fastened. This allows the direct installation and removal of the pipe section to the fully assembled or installed in the vehicle coupling half.
  • the invention also provides that the other, remote from the coupling flange pipe end of the pipe section is open. Since the proposed passive safety element can naturally absorb only a certain amount of energy, the open end of the pipe makes it possible, in the event of a frontal collision, for the support cooperating with the pipe section, depending on the mass and speed of the impacting car or wagons is pushed beyond the open pipe end into the interior of the vehicle body.
  • the coupling flange is provided with preferably formed as a shear pin connecting means for holding the support, which automatically solve at a defined impact force to release the support. This ensures that in light return or shock movements of the coupling of the support in the receiving pipe extension remains intact and only in an emergency on reaching the respective defined impact force is effective by then penetrates into the pipe section to deform this energy absorbing.
  • the support is connected to the pipe section in normal operation with connected shear bolt, so that no operating forces are passed through this shear pin.
  • the breakaway force can be adjusted independently of the shearing force of this connecting means and on the other hand, a setting between the support and the pipe section or a change in the release force over time is prevented.
  • Fig. 1 shows a coupling 1 for a rail vehicle whose unillustrated coupling head to a bolt 2 of a coupling part 3 is articulated.
  • This coupling part 3 has the front side a cylindrical projection 4 with a support 5, which is guided in a star-shaped or the like coupling flange 6 and fixed there by shear pin 7 as a connecting means.
  • the coupling flange 6 in turn is screwed, for example, in the vehicle box of the rail vehicle not shown in detail.
  • a piece of pipe 8 is arranged, which cooperates with the support 5 in an impact as a passive security element by penetrating into the pipe section and widening it, wherein the pipe piece absorbs the energy of the impact within certain limits during its deformation.
  • the support 5 abuts on the enlarged pipe section 8.
  • it could also be provided a distance between these, so that the axial forces arising in normal operation would not be transmitted at these, but on the shear pin. 7
  • the pipe end 9 of the pipe section 8 projects into an annular space 10 between the support 5 and the coupling flange 6 and is detachably fastened thereto.
  • a detachable screw 11 is provided which allows the installation and removal of the pipe section 8 in the finished assembled coupling, even after their installation in the vehicle body of the vehicle. This also makes it possible to retrofit the pipe section 8 in vehicles that originally had no passive security elements. Instead of the screw 11 may also be a bayonet or the like.
  • the pipe section 8 has an identical or varying inside diameter provided continuously in its deformation region and is provided on the inside with a diameter enlargement 12 which accommodates the support 5 at the pipe end 9.
  • These diameter enlargement in the pipe section or in the support are advantageously formed on the outside by a corresponding conical enlargement.
  • the pipe section 8 is well positioned and centered on the support 5. It is also advantageous that the pipe section 8 inside only in the area the diameter extension must be edited. As a result, the processing of the pipe section is greatly facilitated, especially since his pipe length can be in practice a meter and more.
  • a separate flange 14 ' is fixed to the pipe section 8 at the other end of the pipe 14, which is dimensioned with its inner and / or outer diameter such that the impact force via the support 5 counteracting force at this flange 14' opposite the pipe section 8 is variable.
  • this flange 14 'with respect to the pipe section 8 is reduced in size with its inner diameter or enlarged with the outer diameter.
  • the impact force counteracting the impact force is increased in this flange 14 '.
  • This dimensioning can be varied depending on the application and it could also be more than one such flanges 14 'may be provided.
  • the fixation of the projection 4 in the coupling flange 6 with the shear pin 7 has the purpose of preventing the support 5 from becoming unstable in the region of the diameter enlargement 12 as a result of vibrations or light recoils during normal operation.
  • the shear pins 7 Upon impact, the shear pins 7 are sheared off upon reaching a certain impact force, and the support 5 is released so that it can freely penetrate into the deformation region of the pipe section 8 and widening it.
  • the expansion of the pipe section 8 takes place through the support 5 in the region of a plastic deformation, the materials of the pipe and the sliding ring 13 being coordinated with one another are that on impact Support 5 slides against the inside of the pipe section 8 with approximately uniform frictional force.
  • the pipe section 8 is coated on the inside, preferably primed with a base color, while the support 5 is provided with the sliding ring 13 of a sliding material, preferably ductile iron (gray cast iron).
  • This choice of material ensures that, in the event of an impact, the deformation of the pipe section 8 takes place largely without jerks and without an increase in force or force peaks over the entire deformation range of the pipe within certain impact forces.
  • the pipe section 8 is open at its side facing away from the coupling flange 6 pipe end 14 and there opens into a likewise open interior of the vehicle body, not shown, in which the support 5 is encountered in a head-on collision depending on the mass and / or speed of the colliding vehicle.
  • the described passive safety device can be installed both in only one and in both coupling halves of the coupling.
  • the pipe section could be provided with a diameter extension as an annular recess.
  • the pipe section with the pipe end 14 could also be made of a one-piece pipe.
