Definitions

  • the invention relates to a support for a container on the underframe of a railway freight wagon, in particular a tank wagon, according to the preamble of claim 1.
  • the tank For each tank wagon, the tank is connected to a trolley for transport purposes.
  • the known tank wagons can be divided into two construction concepts, tank wagons without a base and tank wagons with a base.
  • the application of the invention relates only to the tank car with a base.
  • the following discussion of the state of the art takes into account the state of the art of the underframe-free tank wagons in the first section for the sake of incorporating the technological environment.
  • the boiler In the tank wagons without an underframe, the boiler is designed to be so stable that it can absorb the operationally occurring forces and tensions, in particular from shock loads, without undue deformation. With this design, a reduction in weight or improved adaptability of the chassis arranged on the boiler to the track conditions can be achieved for certain applications.
  • the connection of the assemblies carrying the train and push device and the bogies to the boiler is problematic, whereby the introduction and reduction of the forces and energy from the buffer joint and in the event of lifting is ensured without excess voltage and inadmissible deformations within the construction got to.
  • the boiler is in the usual way via side saddle rails, which absorb the forces from the deceleration and acceleration of the tank car, and via end saddles, the static weight load and the transverse to the longitudinal direction of the car absorb occurring forces, connected to the base. Due to this rigid connection between the boiler and the base, the tank wagon is also relatively torsion-resistant. In addition to the changes in length of the boiler caused by changes in temperature, whether due to temperature-controlled cargo or different length changes to components or assemblies defined against each other, the connection points between the boiler and the base frame must also absorb the loads caused by the acceleration and weight forces.
  • a support in which one end of the boiler is positively, rigidly fixed on a base and the other end of the boiler is held and guided in a longitudinally displaceable manner by means of pins in a slot.
  • the support is included the form-fitting, rigid connection between the boiler and the base frame is highly stressed during the buffer joint, especially if the buffer joint is carried out at the end of the carriage with the form-fitting, rigid connection.
  • the driving characteristics of this tank car are different in both directions of travel because of the different connection of the boiler to the lower flange, especially in poor track conditions and at higher speeds, and the tank car tends to be unstable.
  • the invention has for its object to provide a support for containers on the base of a rail freight car, in particular a tank car, which to reduce the load at the connection points between the container and Underframe, especially when impacted by buffer impacts on the underframe, contributes and the buffer forces are reduced.
  • the container 1 of the rail freight wagon is supported at both ends A and B in end saddles 2a (end A) and 2b (end B) arranged transversely to the longitudinal direction of the rail freight wagon and can be displaced longitudinally with respect to the base frame 3.
  • a stop piece 4a is attached to the other end B of the container 1, a stop piece 4b.
  • An abutment 5a which is associated with the stop piece 4a and an abutment 5b, which is associated with the stop piece 4b, is fastened to the base frame 3.
  • the abutment 5a of the underframe 3 supports the associated stop piece 4a
  • the abutment 5b supports the associated stop piece 4b in the direction of the transverse median plane of the rail freight wagon.
  • the stop piece 4a and in the direction of the associated end B of the railway freight wagon, the stop piece 4b is freely displaceable in the longitudinal direction.
  • the container 1 is held at its ends A, B on the base 3 in each case freely longitudinally displaceable toward the associated vehicle end A or B and is supported to the transverse median plane of the rail freight wagon.
  • the container 1 is supported and held in the end saddles 2a and 2b with holding elements 6 on the base frame.
  • FIG. 1 shows a schematic embodiment of the invention.
  • the basic mode of operation of the support according to the invention is explained below in connection with an overrun.
  • the impact energy is initially reduced by the buffers in the power flow, as a rule four buffers are involved in the impact, the maximum total buffer work of which is reduced.
  • the buffer impact is passed through the base frame 3, with a further part of the impact energy depending on the design, the spring constant and the damping property of the base frame 3 , is broken down in the base frame 3 by deformation work, friction, heat, etc.
  • the impact energy now remaining reaches the container 1 via the abutment 5b of the base frame 3 facing away from the impact side and the stop 4b. H. for this impact in the abutment 5b and the stop 4b.
  • an energy dissipation device 7a is arranged between the abutment 5a and the stop 4a and an energy dissipation device 7b between the abutment 5b and the stop 4b.
  • the energy dissipation devices 7a, 7b are each only effective in one direction, in the direction of the transverse central plane of the rail freight wagon. This ensures that further impact energy is reduced on the end B of the rail freight wagon facing away from the impact before the impact energy is introduced into the container 1 and the forces introduced into the connection point between the base frame 3 and the container 1 are further reduced at the end facing the other impact A but the energy dissipation device 7a is not acted upon.
  • FIGS. 2, 3 and 4 show a support according to the invention with a spring element 8 as energy dissipation device 7a, 7b.
  • Spring elements 8 with good own damping properties, eg. B. friction springs (disc or truncated cone springs) or rubber springs suitable mixture and suitable structure, since separate damper elements are then usually avoidable.
  • the spring elements 8 can be made biased.
  • FIGS. 5 and 6 show a support according to the invention with an energy dissipation device 7a, 7b which converts kinetic energy (kinetic energy) into potential energy (lifting energy) via inclined planes.
  • the abutment 5a has a bearing surface 10a and the abutment 5b has a bearing surface 10b, the bearing surfaces 10a and 10b each being directed obliquely upwards to the transverse median plane of the rail freight wagon and supported down to the transverse median plane.
  • the contact surface 9a of the abutment 4a lies on the contact surface 10a of the abutment 5a and the abutment surface 9b of the abutment 5b lies on the contact surface 10b of the abutment 5b, the contact surface 9a being correspondingly inclined to the contact surface 10a and the contact surface 9b correspondingly inclined to the contact surface is arranged.
  • the inclination of the contact surfaces 9a, 9b and contact surfaces 10a, 10b are expediently provided to be adjustable.
  • an elastic and / or plastic lining layer 11, for. B. made of lead or plastic, which favors a more uniform introduction of forces into the connection point between the container 1 and the base 3 and increases the slidability.
  • the contact surfaces 9a, 9b and / or the contact surfaces 10a, 10b or parts thereof can be provided with a friction lining 12.
  • a fixed stop 13 it is expedient to limit the displacement of the stop pieces 4a, 4b and thus the displacement of the container 1 against the respectively assigned abutment 5a, 5b or against the underframe 3 at least in the direction of the transverse central plane of the rail freight wagon by means of a fixed stop 13.
  • the fixed stop 13 can itself be supported elastically by means of a buffer element 14 on the base 3 or the fixed stop 13 is provided on the side of the container 1 with a buffer element 14, against which the displaced container 1 comes to rest before the displacement path is used up.
  • the container 1 After the impact impact and the consumption of the impact energy, the container 1 is or is brought back into the starting position in all exemplary embodiments with respect to the base frame 1.
  • the resetting takes place either through the resilience of the energy consuming devices 7a and 7b or with the inclusion of additional resetting devices, the working ability of which is advantageously generated from the impact energy itself.
