Definitions

  • ABSTRACT An articulating system for a central buffer coupling, especially rail vehicles, in which that end portion of the coupling rod which will be adjacent the respective vehicle forms a dish-shaped widened portion which is clamped in between preloaded resilient means, e.g. blocks of elastic material such as rubber material, which are arranged in a housing to be connected to the respective vehicle while a safety bolt preferably extends with play through the dish-shaped portion and the resilient means not only urge the coupling rod to its horizontal and vertical central position, but also absorb push and pull forces.
  • the dish-shaped portion is on the outside confined by an annular rib projecting from the dish-shaped portion to opposite directions, while the dish-shaped portion has perforations with plates of elastic material therein.
  • ARTICULATING SYSTEM FOR A CENTRAL BUFFER COUPLING portion which is clamped between preloaded spring means, especially blocks of elastic material such as rubber material. These blocks are arranged in a housing to be connected to the vehicle while, if desired, a safety bolt may be provided which extends through the dishshaped portion of the coupling rod, and while the spring means not only urge the coupling to occupy its horizontal and vertical central position, but also the buffer system of the coupling.
  • this dish-shaped portion is located horizontally. and is clamped between an upper and lowerrubberblock in such a way that in particular in vertical direction the coupling is placed into central position and that the pull and push forces can be absorbed by the rubber blocks. Since these pull and push forces may become relatively high, the necessary preload of the rubber blocks is determined from the start in order to be sure that the dish-shaped portion will, even with the maximum occurring push and pull forces beheld byfrictional connection.
  • the coupling had to be turnable about the longitudinal axis of the coupling and, more specifically, in both directions while a turning angle of i 4 was permissible.
  • a turning angle of i 4 was permissible.
  • This force requirement was far too high in many instances.
  • the rubber or elastic material had to be so stiffand hard that too high forces had to be employed for the pivoting about the longitudinal axis of the coupling.
  • FIG. 1 is a vertical section through the' articulating system according to the invention, said section extending through the'axis of the coupling.
  • FIG. 2 is a cross section taken along the line ll+ll of FIG. 1. 1 v
  • FIG. 3 is a top view of a dish-sha ped widened portion at the end of the coupling rod. 1
  • FIG, 4 is a section taken along the line lVIV'of FIG. 1. 1
  • the said perforations are at least approximately symmetrically arranged on both sides of the longitudinal axis of the couplingrod.
  • the dish-shaped portion is provided with a central opening which is bordered by arib protruding on both sides of and beyond the surface of the dish,- shaped portion.
  • FIGS. 1 and 2 shows a structure according to which that end of the c oupling rod which is intended to be adjacent the respective vehicle is, through the intervention of a connecting member l 1 connected to the rim of a horizontally located ,dishshaped portion (FIG. 3).
  • a connecting member l 1 connected to the rim of a horizontally located ,dishshaped portion (FIG. 3).
  • Above and below the dish shaped portion 12 there are respectively arranged rubber blocks in the form of a ring 13; 14 respectively, which are preloaded and clamped between the pertaining plates 15 andthe dish-shaped portion 12. Due to this preloading of the rubber blocks 13 and 14, a frictional connection is maintained between the dishshaped portion 12 and the'rubber blocks 13,
  • the plates 15 are turnable about a.
  • the dish-shaped portion 12 has, according to FIGS. 3 and 4, a circular contour which is confined toward the outside by an annular rib 2.2 which projects beyond gitudinal direction of the longitudinal direction of the longitudinal axis of the coupling which coincides with a the section lineIVIV and the-parallel sides 24.of
  • This central opening. 23 is likewise confined by a rib 25 which 'projects on both sides from the surface of the dish-shaped portion.
  • This rib 25 is approximately circular so that the rib within the region of the flattened portion of the central opening 23 is doubled.
  • the ring surface 21 located between the ribs 22 and 25 represents the dish-shaped portion which is in contact with the rubber rings.
  • This surface 21 is formed to about 50 percent or less by the perforations 26 which are located on both sides of the longitudinal axis of the coupling which axis coincides with the section line IVIV.
  • the perforations 26 have an approximately kidney shape and extend in particular at the outer rim up to rib 22.
  • the rib 22 has flattened portions 27, the lowest point of which is located approximately in the center of the perforations 26. The height of this lowest point amounts to approximately 50 percent of the height of rib 22.
  • the rubber rings 13, 14 are, toward the plates 15, made so wide that they fill the flanged rim portions 28 of the plates 15.
  • the rubber rings 13 and 14 are so designed that they completely fill the space between the inner rib 25 and the outer rib 22. Due to the preloading of the rubber rings 13, 14, these rings are firmly seated between the respective horizontal confining sur faces of the rims 28 and ribs 22, 25.
  • the preload of the rubber rings 13, 14 is selected so great that the coupling rod anchored in the connecting member 11 will be able to hold the coupling head arranged at the front end of the coupling rod always at the same height.
  • the perforations 26 in the dishshaped portion 12 are filled by rubber plates 29, the size of which, corresponds to the perforations 26 while the thickness of said'rubber plates 29 corresponds to the thickness of the dish-shaped portion 12.
  • the rubber rings 13, 14 cannot relax within the region of the perforations 26 even though the preload does not act here upon the dish-shaped portion 12.
  • the inner wall of the opening 18 within the region of the parallel straight sections is slightly angled off toward the outside so that a movement about the longitudinal coupling axis 30, according to FIG. 1, will be easily possible even though the distance from the bolt 17 is relatively small.
  • the preload of the rubber rings 13, 14 brings about that the non-illustrated coupling head will always be at the same level as the pull rod. If the coupling head is, according to FIG. 1, pivoted upwardly or downwardly, it will be appreciated that with the pivot movement in upward direction on the front side, ring 13 and on the back side, ring 14 will be compressed whereby the return force will be generated. When the deflecting force ceases, therefore the coupling head will again be returned to the originally set center position.
  • the housing 16 is expediently so designed that it can be inclined to various degrees relative to the vehicle frame whereby the adjustment of the height of the coupling head above the rail will be possible without changing the preload of the rubber rings 13, 14.
  • the dish-shaped portion 12 need, of course, not always have a horizontal position, but may also occupy a vertical position. In such an instance, a few other structural changes are to be effected which, however, cause no difficulty whatsoever.
  • the dish-shaped portion need not be circular, but may also have other contours and will, of course, be selected as it best suits the respective purpose. Due to the magnitude of the perfo rations, the magnitude of the returning force about the longitudinal axis 30 can be varied and adapted to the requirements of the practice.
  • the advantage of the articulating system according to the invention is seen primarily in the fact that with the same line of characteristic for the transfer of the pull and push forces a considerably greater wobbling or rolling softness about the longitudinal coupling axis 30 will be realized.
  • An articulating system for a central buffer coupling especially for rail vehicles, which includes: housing means for connection to a vehicle, a coupling rod having one end portion thereof provided with a dishshaped widened portion arranged in said housing means, preloaded resilient means clamped between .said housing means and said dish-shaped widened portion and clamping the latter therebetween, annular rib means peripherally connected to said dish-shaped portion and projecting therefrom in opposite directions in the axial direction of said dish-shaped portion, said dish-shaped portion being provided with perforations, and plate means of elastic material provided in said perforations.
  • annular rib means is lower within the region of said perforations than within the remaining region of said dish-shaped portion of said coupling rod.
