Definitions

  • the invention relates to a bearing block for the articulation of a coupling rod to a car body of a track-guided vehicle, in particular rail vehicle.
  • Such a bearing block is for example from the DE-U-20 2005 004 502 known.
  • a bearing block usually serves to connect a coupling rod in a horizontal plane pivotally connected to the car body of a rail vehicle.
  • the coupling rod can also perform pivotal movements relative to the car body, which is required, for example, when cornering a multi-membered train, the realized via the bearing linkage is usually designed so that a horizontal and vertical swinging and axial rotation of the coupling rod relative to the Car body is made possible.
  • FIG. 1a is a perspective view of a known from the prior art bearing block 101 for coupling a central buffer coupling to the car body of a rail vehicle shown.
  • Fig. 1b shows the bearing block 101 according to Fig. 1a in an exploded view.
  • Fig. 1c is the bearing block 101 according to Fig. 1a shown in a plan view, while a sectional view along the line AA (see. Fig. 1c ) in Fig. 1d is shown.
  • the in the FIGS. 1a to 1d Exemplary illustrated conventional bearing block 101 has a arranged in a vertical plane flange 102, via which the bearing block 101 can be connected to the car body of a rail vehicle or a subframe thereof.
  • the car body or the Wagenkastenuntergestell is not shown.
  • the bearing block 101 is bolted via the flange 102 to the car body or car body underframe.
  • the bearing block 101 used in a conventional clutch linkage has a cage or housing structure 120 which extends from the flange 102 in the coupling direction and an upper and lower fork arm 114, 115 has.
  • a first bearing shell 103 is attached by means of shear screws 105.
  • a second bearing shell 104 is likewise attached to the lower fork arm 115 by means of shear screws 106.
  • the first and second bearing shells 103, 104 together define a bearing for a vertically extending pivot pin 110.
  • the two bearing shells 103, 104 for this purpose each have a corresponding receptacle 107, 108, in which the respective end portions of the common pivot pin 110 are received.
  • the vertically extending pivot pin 110 accommodated in the receptacles 107, 108 of the first and second bearing shells 103, 104 serves to articulate one in the FIGS. 1a to 1d not explicitly shown coupling rod of a clutch assembly.
  • About the vertically extending pivot pin 110 of the coupling shaft of a central buffer coupling to the bearing block 101 is pivotable horizontally articulated.
  • first and second pivots are used to at least partially receive a trained in the form of an elastomeric spring device Anlagen- / shock device within the cage or housing structure 120 of the bearing block 101 in a horizontal plane.
  • the flange 102 of the bearing block 101 is not in a vertical plane through which a through the respective receptacles 107, 108 of the bearing shells 103, 104 defined axis of rotation R runs. Rather, the vertical flange plane is spaced in the direction of the car body from the vertical pivot axis R defined by the receptacles 107, 108 of the bearing shells 103, 104. This is in particular with reference to the illustration in FIG Fig. 1d recognizable.
  • the vertical flange plane is horizontally spaced from the vertical axis of rotation R, which is defined by the receptacles 107, 108 in the bearing shells 103, 104. This distance is necessary in the Kupplungsanlenkung so that in the cage or housing structure 120 of the bearing block 101 at least partially recorded pull / push device under pressure relative to the bearing block 101 in the direction of the car body (ie in the direction of flange 2) can move to In this way, compressive forces can regeneratively dampen.

  • the shear screws 105, 106 are designed so that when a critical force acting on the pivot pin 110 in the horizontal direction is exceeded, this compressive force shears off and thus loses its connection function. After shearing the corresponding shear screws 105, 106, the pivot pin 110 is displaced together with the first and second bearing shell 103, 104 in the direction of the flange 102.
  • the present invention is based on the problem that in a conventional, for example, with reference to the representations in the FIGS. 1a to 1d illustrated bearing block 101 is not ensured that in a crash, the shear bolts 105, which connect the upper fork arm 114 of the bearing block 101 with the first bearing shell 103, simultaneously with the shear screws 106 respond that connect the lower fork arm 115 with the second bearing shell 104.
  • a Time-delayed response of the corresponding shear screws 105, 106 may be caused, for example, by either the upper or lower fork arm 114, 115 of the cage or housing structure 120 of the bearing block 101 deforming prior to the response of the corresponding shear screws 105, 106.
  • a delayed response of the shear screws has the disadvantage that the connection between the first and second bearing shell with the associated fork arm of the cage or housing structure of the bearing block is not solved at the same time.
  • a trunnion received in the first and second bearing shell threatens to perform a tilting movement in such a scenario, as a result of which tilting of the pivot pin or of the coupling rod pivoted to the pivot pin in a horizontal plane can occur. Then it is no longer ensured that the coupling rod can be removed from the power flow, so that overall the event sequence occurring in a crash is no longer predictable.
