Definitions

  • the invention relates to a central buffer coupling with a device for elastically supporting a coupling shaft on a rail vehicle according to the preamble of claim 1.
  • Such a central buffer coupling with device is z. B. from DE 27 01 984 A1.
  • the coupling shaft is supported both in the direction of its axis when acting on the central buffer coupling tensile and impact forces and in the vertical direction relative to the rail vehicle.
  • the device furthermore has a housing which is open towards the central buffer coupling and whose axis extends in the vehicle longitudinal direction and into which the coupling shaft projects coaxially with a radial distance from the inner peripheral surface of the housing.
  • resilient rings of elastic material are provided between the peripheral surfaces of the coupling shaft and the inner peripheral surfaces of the housing prestressed. The rings are vertically aligned with their center planes and arranged at a mutual distance in the shaft longitudinal direction.
  • the rings are respectively held in the spaces between two adjacent circumferential annular beads on the peripheral surface of the coupling shaft and on the inner peripheral surface of the housing relative to the coupling shaft and the housing.
  • the housing and the coupling shaft and the rings have an oblong-round cross section, the largest diameter of which lies in the horizontal center plane of the housing or of the coupling shaft.
  • the housing is divided in its horizontal center plane in two half-shells, which are interconnected by means of releasable fastening means.
  • the rings are separated in the horizontal center plane of the housing at least on one side, wherein each ring rests directly on both the peripheral surface of the coupling shaft and on the inner peripheral surface of the housing. In the unloaded state of the device, so if no tensile or impact forces the device acting, aligned the annular ridges of the coupling shaft with the associated annular beads of the housing.
  • the invention is therefore based on the object to improve the generation and adjustability of the bias of the spring apparatus of the device described above.
  • a bearing block 1 fastened to a rail vehicle, not shown, is connected via pins 2 to a housing 3 which coaxially surrounds a coupling shaft 4 carrying a central buffer coupling at a radial distance, wherein both the coupling shaft 4 and the housing 3 preferably have a round cross section or have a cross section with a long and a short axis, whose larger diameter is arranged in the horizontal center plane of the housing or the coupling shaft.
  • the inventive solution is also suitable for genus-like devices with any cross section of the housing 3 and coupling shaft 4.
  • Both the coupling shaft 4 and the inner circumference of the housing 3 are provided with circumferential ring deserts 6 and 5, which are aligned with each other in the unloaded state of the device.
  • the ends 7 of the housing 3 are drawn in to form end-side annular beads 5 inwardly, while the ends associated shoulders 8 of the coupling shaft 4 are formed accordingly.
  • the coupling shaft 4 is arranged in the predetermined radial distance from the housing 3 by perpendicular to the vehicle longitudinal direction, inserted between the ends 7 and the shoulders 8 and the annular beads 5 and 6 rings 9 made of elastic material, for. As rubber or plastic, held.
  • the housing 3 consists of two identically formed, by means of screws 10 releasably connected to each other shells, and the rings 9 are formed on one or both sides slotted.
  • the rings 9 are installed at a certain degree over the screws 10 with bias perpendicular to the coupling shaft longitudinal direction, whereby a tight fit of the rings 9 between the coupling shaft 4 and housing 3 can be produced.
  • the coupling shaft 4 has at its opening facing the housing opening a collar 11 against one side of a biasing ring 12 with its rear side and against the other side of the opening of the housing nearest ring 9 rests with its front, wherein the biasing ring 12, the rings 9 biased in unloaded position of the device in the coupling shaft longitudinal direction.
  • the biasing ring 9 is inserted in a circumferential trough-shaped recess 13 of the coupling shaft 4 and a similar recess 13 of the housing 3.
  • the recesses 13 have chamfers 14, to which the biasing ring 9 (rolling ring) is guided.
  • the chamfers 14 of the housing 3 and / or the coupling shaft 4 are flattened in the direction of the housing opening than the axially opposite chamfers 14, which have at most an angle to the coupling shaft of 90 ° or merge into the collar 11.
  • the bias of the device by means of the biasing ring 12 in the coupling shaft longitudinal direction, d. H. in the pressure or impact direction, can be done as in the embodiment of FIG. 1 and FIG. 2 by connecting the parts of the split housing, usually by screws 10th
  • the generation and adjustment of the biasing force takes place in the longitudinal direction of the coupling shaft 4 via a pressure piece 15, which on the housing by means of screws 16 is attached and supported.
  • the pressure piece 15 may have an additional adjusting device (not shown) for fine adjustment.
  • the device can be designed with one or more rings 9.
  • the number of rings 9 and the annular beads 5 and 6 is determined according to the size of the male forces, with a higher number of rings 9 allows a higher load capacity.
  • the biasing ring 12 are taken through the collar 11 and the rings 9 through the desert 6 of the ring shaft 4. Since the biasing ring 12 and the rings 9 on the other hand are held by the housing 3, the rings 9, 12 are elastically deformed over the entire cross section, although initially the bias in the biasing ring 12 and the rings 9 is reduced by the amount of tensile force.
  • the amount of the biasing force in the longitudinal direction of the coupling shaft 4, d. H. the coupling shaft 4 is biased in the pressure or impact direction is greater than the maximum, operationally occurring tensile force on the coupling shaft 4 is provided. This ensures that the device always remains under a certain bias even with train-pressure-load changes, which leads to a quieter, vibration-free run of coupled via these devices rail vehicles.
  • the rings 9, on the one hand entrained by annular beads 6 of the coupling shaft 4 and on the other hand held by the annular beads 5 of the housing 3 are elastically deformed over the entire cross-section, wherein a stress of the rings 9 takes place initially on thrust .
  • the shear stress gradually shifts to compressive stress as the rings 9 are increasingly compressed between each two successive annular beads 5 and 6 so that the rings 9 are eventually prevented from further deformation.
  • the biasing ring 12 remains substantially unloaded, since the flatter run-on slopes 14 to the side of the housing opening allows him to escape.
  • the coupling shaft 4 is subject to a downward moment by its weight and the weight of the central buffer coupling. For perfect coupling, however, the coupling shaft must always be approximately in the horizontal center position.
  • the biasing ring 12 is given a vertical support, which acts in addition to the support through the rings 9. Because of the larger support base therefore longer coupling shanks 4 or higher weights can be supported without additional vertical support in types with biasing ring 12.
