Definitions

  • the invention relates to a length-adjustable coupling rod with all sides acting directional joints for rail vehicles according to the generic terms of Claims 1 and 6.
  • coupling rods For loading length adjustment, especially for wagon units for the combined vehicle Cargo traffic are known coupling rods, in which the plugging in multiple times existing articulation points within the length of the coupling rods and Pick-up points in the base frame is achieved.
  • Freight cars equipped with coupling rods must comply with the international Regulations tight full arches with simultaneous action of longitudinal thrust forces in Height of at least 50 t resulting from the reloading process can go through.
  • Coupling rods with ball joints require high dead weights, to meet the requirements of running safety. Extension rods are again Advantageously necessary, since this involves a largely automatic length change Controlled cheaply from the adjacent vehicle parts from railway technology can be.
  • Existing known articulated coupling rods all go from one Arrangement of the directional joint on the coupling rod ends.
  • the structure is in the Usually through the use of coupling rod-attached coupling rod ends Drawbar that encloses a telescopic spring device and is loose or fixed Support bearing supported between the clutch carriers, marked.
  • EP-A-727338 describes a length-adjustable coupling rod for rail vehicles described in which the change in length by changing the existing Coupling rod articulation points and the mounting points in the base.
  • a coupling rod is used which is elastic on the pressure side against the support bearing parts of a telescopic suspension and damping element supported in an articulated manner via spherical abutting surfaces.
  • the transmission of the train side The forces are exerted by a pull rod running through the carriage, which ends at the Coupling rod is connected in an articulated manner.
  • a length-adjustable coupling rod of the type mentioned with all-round directional joints to create a largely automatic Conversion of the loading lengths with automatic engagement of the coupling bolts is suitable and which is stabilizing to solve the problems of derailment security Joints with high efficiency and a largely straight line Have power transmission with low weight and low costs in the Manufacture and maintenance of the coupling rod.
  • Coupling rod movable articulated support bearing is arranged, which is rigid, but detachable with the base via plug pairs of the freight car is connectable. It is also essential that the articulated support bearing has a centering opening on the pressure receiving side, which has a centering stump which from the middle of the directional joint plate, in which the spatial roll curve and the resulting spherical cap is integrated, protrudes.
  • the invention ensures with the proposed installation conditions and rectilinear power transmission and the movement possibilities of the directional joint high effectiveness.
  • FIG. 1 shows a top view of half of a coupling rod 3 according to the invention with a total of four articulation points. Compression forces F XL in the coupling rod 3 act in the specified direction.
  • a breakthrough 19 of the coupling rod 3 is shown, wherein a directional joint plate 4 is fixedly connected to the coupling rod 3, which has a rolling curve 5 with a spherical surface and has a centering stub 8 with an insertion cone 9 in the longitudinal center of the coupling rod 3 which is received by a centering opening 10 in a directional joint support bearing 2.
  • the articulated joint support bearing 2 is movably mounted in an opening 19 in the coupling rod 3, but is fixedly but releasably connected to an underframe 1 via a pair of plug pins 17.
  • the directional joint support bearing 2 has a ball joint attachment 7, which finds its counterpart in a tension plate 6, the joint contours following the radius around a central tipping point M1.
  • a spring 13 for tensile forces is arranged. With its pretensioning force, this spring 13 ensures that all parts are supported in the opening 19 of the coupling rod 3 without play, for the required damping effect of the coupling rod 3 and for a smooth tilting and rolling process of the directional joint.
  • the centering stub 8 which engages in the centering opening 10 in the articulated support bearing 2 has a lateral surface which follows a tilting radius R A around an initial tilting point M2 and the centering opening 10 has the same contour, however, which is subject to play.
  • FIG. 4 there is a further design option that right and on the left side of the springs 13 for tensile forces, the tensile washers 6 with ball joint lugs 7 are present, the one in the directional joint support bearing 2 and the other in one Engage end plate 18. This design ensures that the parts are highly flexible in the opening 19 of the coupling rod 3.
  • the articulated support bearing 2 Zaan Farbarme 15, wherein between the articulated support bearing 2 and the Weranschlagarmen 15 die Articulated plate 4, which is connected to the coupling rod 3 axially - longitudinally displaceable is a spring 14 for tensile and impact forces and a pressure-tensile washer 12 to be ordered.
  • the advantage of this design is that both Werwie shock forces can also be absorbed directly.
  • a single plug-in slide with e.g. Square cross-section is used instead of the socket pair 17 for torsionally rigid locking of Articulated joint support bearing 2 in the base frame 1, a single plug-in slide with e.g. Square cross-section is used. It would be advantageous to reduce the Number of locking parts.
  • the Articulated joint plates 4 are designed as detachable individual parts and one each applicable radius R - Ri with at least half the size Obtain coupling rod length. This is advantageous because within a coupling rod 3 different radii and thus calottes are required for rolling curves 5.
  • a length-adjustable coupling rod 3 with all-round directional joints is created, which is suitable for an automatic length change, has an effective directional joint and thus contributes to solving the problems of the running safety of light-weight vehicles and represents a weight and cost-saving solution. This makes a contribution to improving the economy of freight transport, especially in combined transport.
