Definitions

  • the invention relates to a coupling head of an automatic central buffer coupling for rail vehicles in the manner of a Willison coupling with the Willison contour (also called Willison profile) according to the preamble of claim 1.
  • Willison couplings are z. B. from the DE-OS 15 30175 and the DE-OS 14 55 242 known.
  • the object of the present invention is to provide such a designed coupling contour of a coupling head of the type mentioned, the very small games in Kupplungslhacks- and transverse coupling direction produced, but at the same time ensures the coupling and decoupling similar couplings and also converts the compatibility with the existing couplings with the standard contour.
  • the essence of the invention is to change the proven and successful dimensioning of the standardized Willison contour to the effect that the clutch and load transfer characteristics obtained and only the previously occurring in mutually coupled coupling heads game is minimized.
  • it is provided to increase at least one of the guiding, centering, insertion and / or support surfaces relative to the known contour, for example by a uniformly applied overlay layer or by appropriate dimensioning during finishing, so that the play is coupled together, especially when new Coupling heads is almost zero, in particular less than 4 mm.
  • the invention allows a jam-free coupling and decoupling with the specially dimensioned elevated machinable contact surfaces of the train contour and transverse to the clutch longitudinal axis contact surfaces outside the small tooth and inside the large tooth of the clutch and the specially designed pressure contour in the clutch bag.
  • the contour of the contours is the area of the Willison contour, which comes into contact with the small and large tooth when the traction transfer takes place.
  • the pressure contour is the area of the Willison contour that comes into contact with the small tooth and the clutch pocket on the pressure-side inner contour when pressure is transmitted.
  • a particular advantage is that only special areas are designed differently. These flat surfaces are accessible for mechanical machining with standard tools, without the production process being made more expensive by the necessity of using special tools.
  • the coupling head 20 of an automatic central buffer coupling 100 has the known Willison contour with a small coupling tooth 27 and a large coupling tooth 9 corresponding guide surfaces of the pressure contour 13, the Switzerlandkontur 14, the support surface 12 and the clutch bag bottom 10th
  • the large clutch tooth 9 also called large clutch claw
  • the coupling connection is "made rigid" in a simple manner, d. h., Relative movement of the two intermeshing coupling heads 20 in the vertical direction is thereby reduced to the required minimum.
  • the small coupling tooth 27 (also called small coupling claw) has two mutually approximately parallel guide surfaces of the pressure contour 13 and the Wertur 14 and a standing at an angle support surface 12.
  • the clutch pocket 18 also has two mutually approximately parallel guide surfaces of the pressure contour 13 and the Wertur 14, which are associated with the guide surfaces of the pressure contour 13 and the Wertur 14 of the small clutch tooth 27, and a clutch bag bottom 10, which is aligned according to the support surface 12.
  • the coupling contour 19 of FIG. 1 is on the contact surfaces of the train contour 14 with respect to the standardized Willison contour according to UIC Leaflet 523, Appendix 1, designed to approximately 2 - 4 mm increased and has at the transverse to the clutch longitudinal axis 3 clutch bag bottom 10 in large tooth 9 and the corresponding surface of the small tooth 12 an elevated contour, wherein the pressure-side inner contour 1 of the coupling profile 19 from the coupling point 2 of the intersection of the longitudinal axis 3 with the Kuppelebenenroughline 4 parallel to a straight line 5 through the coupling point 2 approximately at an angle to the coupling longitudinal axis 3 in the direction of the pressure contour 13 lying of about 62 ° and preferably at a constant distance 7 of about 35 mm to the fillet radius 8 in the large tooth 9 runs.
  • FIG. 2 shows the planar design of the contact surface of the coupling pocket bottom 10 lying transversely to the coupling longitudinal axis 3 in the large tooth 9.
