Definitions

  • the invention relates to a device for mounting a superstructure of a railroad car on its underframe with rollers arranged between the superstructure and the underframe and a long-stroke shock absorber that dampens a shock acting on the railroad car.
  • Long-stroke shock absorbers with sliding frames are installed between the body and the underframe in order to protect the load from damage due to impact.
  • Carriages with bumper beams are also known.
  • a beam passing under the railroad car is articulated to the rest of the car's underframe using a shock absorber. This shock absorber absorbs part of the shock energy.
  • the impact beam resumes its central position.
  • the bumper beam is an additional element on the vehicle and leads to a heavier construction.
  • the version with sliding frame does not use the bumper beam.
  • the base frame can have a limited path under the slide frame to reduce the acceleration of impact.
  • the long stroke shock absorber absorbs shock energy and returns the slide frame to the central position after the shock has subsided.
  • the slide frame is mounted on the base frame in a sliding and / or rolling manner.
  • Roller bearings on several large, heavy, fixed rollers, which are placed on the base frame, are known.
  • Loose rolls, which are guided in so-called roll boxes, are also known.
  • Sliding plates for slidably receiving the sliding frame on the base frame are also known.
  • the object of the present invention is therefore to enable the structure to be stored on the base frame in a space-saving and weight-saving manner, which ensures reliable operation of the long-stroke shock absorber.
  • roller blocks provided with a plurality of rollers are arranged in the area of the contact surfaces of the base frame.
  • a device has the advantage that a sliding frame and / or a bumper beam can be dispensed with, as a result of which considerable weight savings are achieved.
  • the equipment of the roller boxes with several comparatively small rollers has the advantage that the height of the storage can be reduced.
  • a railroad car equipped according to the invention can be made lighter since the remaining accelerations can be in the range from 0.5 to 1 g.
  • refrigerated trucks can also use simpler cooling units, such as are common for trucks. As a result, the additional effort for the installation of a long stroke shock absorber can be compensated for, so that a railway car equipped according to the invention is not significantly more expensive than a conventional, undamped vehicle.
  • the invention in a shock-absorbing railroad car with a body 1 and its associated base frame 2, which are connected to one another via a long-stroke shock absorber 3, the invention essentially consists of roller blocks 5, which are arranged in console-shaped square openings 7 on the base frame and each have a plurality of rollers 6 have, which are supported on opposite lanes 4 on the body 1.
  • the number of roller blocks 5 and the number and arrangement of the rollers 6 arranged in each roller block 5 are preferably selected in a load-optimized manner in the sense that a higher number of roller blocks 5 and rollers 6 are arranged over the entire length of the vehicle in railway carriages with a comparatively high load to be expected than with vehicles with an expected lower weight load from the cargo.
  • the roller blocks 5 each preferably have four rollers 6, which are also preferably arranged in pairs next to and behind one another.
  • the rollers 6 are rotatably mounted in fixed positions.
  • the roller blocks 5 are arranged in the area of contact surfaces 12 of the base frame 2 in the square openings 7, which form the contact surfaces 12.
  • Elastic bases 8 are inserted into the square openings 7, on which the roller blocks 5 are supported elastically in order to compensate for angular deviations of the rollers 6 from one another in the event of an impact load.
  • This elastic pad 8 can consist, for example, of a rubber plate.
  • the mating tracks 4 for the roller blocks 5 consist of hardened flat material which is located on the underside of the structure 1 in the area of a roller block 5.
  • the roller blocks are removably inserted into the square openings 7.
  • Adapted adapters can be used optionally in one or more square openings 7 on the base frame, each of which is provided with a slide plate 11 on which the mating track 4 assigned to it is slidably mounted.
  • the railroad car is provided at least in the area of its four corners 13 with an anti-lift device 14, each of which consists of a clamp 9 fastened to the base frame 2 and a guide rail 10 which overlaps it and into whose recess 15 the clamp 9 protrudes.
  • an anti-lift device 14 each of which consists of a clamp 9 fastened to the base frame 2 and a guide rail 10 which overlaps it and into whose recess 15 the clamp 9 protrudes.
  • clamp 9 and guide rail 10 are designed contactlessly in such a way that lifting of the body 1 is prevented, but the rolling or sliding mounting of the body 1 with respect to the base frame 2 is not impeded.
  • the bracket 9 is preferably releasably attached to the base frame 2. So that for the In the event of an intended replacement of one or more roller blocks 5 with adapters with sliding plates 11, the structure 1 can be lifted off the base frame 2 with little effort, and equipment with roller blocks 5 and / or sliding plates 11 can be provided as required.
  • a kinematic reversal of the device according to the invention is of course also possible in such a way that the roller blocks are fastened to the structure 1 and the mating tracks are located on the underframe 2, preferably in the area of their side members.
  • the anti-lift device 14 can also be designed in such a way that a clamp is provided on the structure 1, while a guide rail is arranged on the base frame 2.
  • the base frame 2 can be designed with a rigid base plate in order to ensure the movement space of the body 1 relative to the base frame 2. However, a further support of the base plate in the area towards the center is also possible, so that a rigid construction of the base plate is then not necessary.
  • the structure 1 can also be designed as a torsionally rigid box, e.g. like an isothermal build-up.
  • the body 1 can take on part of the required torsional rigidity of the vehicle so that the railroad car is safe against derailment. This is primarily necessary for two-axle freight cars. If the underframe 2 is made less torsionally stiff, weight can be saved, which enables a higher payload for the railroad car.
