Definitions

  • the invention relates to the profiling of a heart of a switch for traffic routes of rail vehicles.
  • the wheel of a rail vehicle driving the switch is transferred from a wing rail to a centerpiece.
  • the centerpieces of the prior art have a ramp.
  • This ramp begins at the practical frog point and runs linearly rising on top of the centerpiece.
  • K-point the ramp goes with a kink in the "normal", i. not machined part of the heart over, which is at the height of the upper rail edge of adjacent rail sections, in particular of the opposite rail.
  • a shift of the K-point takes place, in particular, by 1000 mm in the direction of the turnout end, resulting in a so-called “long” ramp.
  • the point N in the form of a training "Knickrampe" with a course, which is in an area around the theoretical Radlauflauf, the point CC, almost parallel to the upper edge of the wing rail.
  • transitions between individual areas of the ramp do not have to take the form of a kink, but can also be designed to be continuously differentiable. In this case, the transition between individual areas takes place in a sliding and rounded manner. Likewise, individual areas need not be linearly rising or horizontal, so that the ramp can advantageously have a curved profile.
  • the invention provides a reduction of the stress level (vertical forces) of the core through a (nearly) constant and flat inclination of Radabsenkungskurve. This applies both to the area of the theoretical wheel overflow and the subsequent center piece ramp. This results in a particularly advantageous longer life and greater profile accuracy.
  • a wheel is transferred from the wing rail 1 to the frog 2 when driving on a turnout in the direction of travel 4. This transfer takes place in point CC.
  • the heart 2 of the switch has a ramp 3 to make the transition of the wheel of the wing rail 1 on the core 2 without major abrupt movements.
  • the ramp 5 and the profiling line 7 of the core according to the prior art is formed linearly rising from the practical tip N of the core 2 to the K point K SDT .
  • a ramp 6 according to the invention or the profiling line 8 of the frog in the first region after the practical tip N of the frog 2 is likewise formed in a linearly increasing manner.
  • the first area is adjoined by a second area in which the ramp is formed horizontally. In this second area, the transfer of the wheel takes place on the heart 2.
  • the second area is followed by a third area, which is formed linearly rising up to the shifted in the direction of the point end K-point K kink .
  • Fig. 4 shows the difference of Radabsenkung in overflow of a wheel (wheel profile S1002) over a heart, using the example of a simple heart piece of the type EH 60 - 500 - 1:12, with a ramp according to the prior art, shown with a thin line , and according to the invention, shown with a bold line. It can be seen that the minimum of the curve for the ramp according to the invention, which lies in the region of the transition of the wheel from the wing rail 1 to the core 2, is widened. This results in FIG. 5 to a significant reduction of the Q-force and thus to a smoother transition of the wheel of the wing rail 1 on the core 2. In this case, the pointed driving the switch with a locomotive at a speed of 120 km / h simulated.
  • the evaluation of the results from the simulation calculations is based on the wheel reduction and the Q force curve. It can be seen that there is a direct relationship between the maximum of the Radabsenkung, the slope of Radabsenkungskveve from the point of theoretical wheel overflow (maximum reduction) towards the turnout end and the resulting Q-force in this area for the impact and subsequent lifting of the wheel.
  • the curves of the wheel reduction for a wheel profile S1002 shown in FIG. 4 show that the ramp shape according to the invention has the desired (almost) constant and flat inclination from the point of wheel transfer.
