Definitions
- the invention relates to a trained according to the preamble of claim 1 Drawbar.
- the tractive force of a vehicle is transferred to the following vehicles usually via a towing device, one at a Compression spring device supported tie rod.
- the compression spring device has one between a support and a non-positively connected to the pull rod Pressure plate clamped spring element.
- a pull hook is arranged at the end of the drawbar on the train side.
- the compression spring device exists a first outer spring system designed as a hollow body and a second inner spring system formed by two tubular spring elements.
- the tubular spring elements of the inner spring system each have a tubular and provided with a circumferential groove on metal carrier, which has a force and / or a frictional connection is connected to the first spring element.
- the metal support is each made of a tubular one made of elastomeric plastic Surround element which is resilient in the axial direction.
- the outer spring system is first subjected to tensile load and then according to a specified one
- the second spring system also takes effect.
- the second spring system thus forms a kind of "elastic stop".
- the object of the invention is to define one in the preamble of claim 1 Train equipment for rail vehicles so that they are inexpensive can be manufactured and the spring element against overload and damage is protected.
- a stop is formed to limit the axial spring travel in a simple manner and there is a significant cost saving compared to the prior art.
- a spring element with a steep increase in force and then a largely linear, gently rising spring characteristic are used, since damage to the spring element is prevented by the end stop.
- this also enables the use of a spring element, the maximum of which Force absorption is below the maximum permissible tractive force.
- the pulling device shown in FIG. 1 has a pulling arm 1, which is only hinted at is shown. At the not visible front end of the pull arm 1 is a Draw hook arranged.
- the pull arm 1 is secured by means of a secured bolt 2 Clevis 3 connected.
- a screw provided with a head 5 forms a pull rod 4, which is provided at the end with an external thread 6 and at 7 in the is screwed with an internally threaded fork head 3.
- the clevis 3 is guided in a tapered opening 11 of a support 9.
- Coaxial around the pull rod 4 is an existing made of elastomeric plastic and as a hollow body arranged in the form of a bellows open on both sides spring element 12.
- the spring element 12 is supported in the pulling direction on the support 9, in the opposite direction, So on the vehicle side, on a pressure plate 13.
- the pressure plate 13 in turn is supported on the vehicle end on the head 5 of the pull rod 4.
- the spring element 12 is biased.
- the Support 9 provided with a base plate 8, in which holes 18 are inserted.
- the support 9 and the pressure plate 13 are each with an annular, the spring element 12 facing extension 10, 14 provided. Both extensions 10, 14 eri Extension 10 as well as the pressure plate 13 with its extension 10, 14 are in one piece educated.
- the two extensions 10, 14 together form a stop that the axial displacement -Federweg- the pull rod 4 limited in the pulling direction.
- Preferably both the support 9 and the pressure plate 13 in cast or Forging technology manufactured.
- the two extensions 10, 14 also serve as Centering and as an inner radial support of the spring element 12. Corresponds to this the outer diameter of the two extensions 10, 14 with the inner diameter of the spring element 12 in its respective end region.
- On the top is the spring element 12 provided with a flattening 15, but in the present case only the installation situation is taken into account.
- a symmetrically designed spring element 12 can be used.
- the end face 14a of the one extension 14 lies on the end face 10a of the other extension 10 and prevents further displacement of the pull rod 4 in the direction of pull
- Fig. 2 shows a plan view of the pulling device. From this illustration it can be seen that the base plate 8 of the support 9 is provided with four fastening holes 18 is.
- the exemplary embodiment of a pulling device shown can be quick, simple and inexpensive are manufactured. Limiting the travel can cause damage of the spring element 12 can also be prevented if too high or tensile forces outside the specification act on the drawbar. Furthermore can spring elements with largely linear spring characteristics be used. Finally, the proposed training will also make the Use of spring elements enables their maximum force absorption below the maximum permissible tensile force of the drawbar.
- guide functions of the tie rod 4 can both avoided with respect to the support 9 and also with respect to the spring element 12 become.
- the pull rod 4 is guided over the fork head 3 in the support 9.
- the Spring element 12 is form-fitting via the two annular extensions 10, 14 centered. Wear-reducing pads, such as those used in known pulling devices, where relative stroke movements between the guide rod and stop or Spring elements occur can be dispensed with in the present case.
- the highly loaded tie rod 4 is still protected against harmful wear.
