Definitions

  • the invention relates to a train device for rail vehicles according to the preamble of claim 1.
  • the clevis and the actual tie rod are made in one piece Wrought iron made.
  • the drawbar must be machined after forging be reworked. Forging long workpieces with a small cross-section and post-processing is complex and therefore expensive.
  • the object of the invention is now one in the preamble of claim 1 Define defined pulling device for rail vehicles so that they are inexpensive can be manufactured.
  • the pulling device according to the invention results in comparison with the prior art a significant cost saving, which can be up to 20%. Moreover, the installation length is significantly reduced by the pulling device according to the invention.
  • the pull rod is expediently provided with a mechanical end at the pull end Provide fuse. It has proven advantageous to pull the tie rod on end to be provided on the traction side with a groove which is used to accommodate the mechanical Securing in the form of a snap ring or a two-part locking ring is trained.
  • the clevis is in the area of the pull-side end of the pull rod preferably with a hollow cylindrical section surrounding the pull rod provided, the inner diameter at least approximately the outer diameter of the snap ring or circlip. This ensures that the mechanical fuse cannot jump out of the groove.
  • a thread rolled threads for example M60x2
  • M60x2 have proven to be particularly advantageous proven.
  • the traction device shown in FIG. 1 according to the prior art a pull arm 1, at the front end, not shown, a pull hook is arranged is.
  • the pull arm 1 is by means of a secured bolt 2 with the fork head 3 connected.
  • the latter goes into the actual tie rod formed in one piece with it 4 over.
  • Both the clevis 3 and the tie rod 4 are in one Support 5 out.
  • Coaxial around the tie rod 4 are made of elastomer Plastic existing spring elements 6 arranged, which under themselves by washers 7 are separated.
  • the spring elements 6 are supported in the pulling direction on the support 5, in the opposite direction, that is to say on the vehicle side, on a pressure plate 8.
  • the pressure plate 8 is at the vehicle end of the tie rod 4 by means of a crown nut 9 secured, the latter in turn secured by a split pin 10.
  • the support 5 lies in the direction of pull on laterally arranged pull stops (not shown); it is normally not loaded in the opposite direction. Held the support is attached using 4 screws that attach the base plate to the support connect the side members of the vehicle are not shown.
  • the pull rod 11 formed by a screw 12 provided with a head 13, which is provided at the end with an external thread 14a and at 14 in the with a Internal thread 14b provided fork head 3 is screwed.
  • thread 14a, 14b rolled threads for example in the dimension M60x2, are special proven advantageous.
  • the screw head 13 also serves as a stop for the Pressure plate 8. The assembly is carried out in an analogous manner to that described Towing device according to the prior art by the spring elements 6 strongly pressed together be while the screw 12 is screwed in.
  • the threaded connection 14 is on the one hand by stops on the pressure plate 8, which on the Head 13 of the screw 11 act, and on the other hand by a mechanical lock secured.
  • the mechanical securing of the screwed-in tie rod 11 is performed by a two-part locking ring 16 formed in a groove 17 of the tie rod 11 is recorded.
  • the fork head 3 in turn is in the area of the train end the pull rod 11 with a hollow cylindrical portion surrounding the pull rod 11 18 provided, the inside diameter of which is at least approximately the outside diameter the locking ring 16 corresponds. This ensures that the locking ring 16 cannot jump out of the groove 17.
  • On the above hollow cylindrical section 18 is followed by a section 19 which is a larger one Inner diameter or a larger opening width than the hollow cylindrical Section 18 has.
  • the illustrated embodiment of a traction device can be quick, simple and can be manufactured inexpensively.
  • the tension screw 11 or the clevis 3 possibly replaced individually and / or be made from different materials.
