- the lower part of FIG. 5 shows that the coupling mechanism 152 in the position of the locking element 166 located in the unlocking position 170 is pivotable at the point P2 relative to the remaining coupling arm 148.
- a coupling arm of another rail vehicle 154 coupled to the rail vehicle 150 can be easily decoupled from the center buffer coupling 146 as the deflection 172 causes one of the levers 160 to strike a stop 164. This can, for example, in the case of a track offset between the

- FIG. 7 shows a schematic representation of a rail vehicle according to the invention in a preferred embodiment.
- the rail vehicle 188 is a railroad car in this embodiment. This has in each case a central buffer coupling 146, 174 according to the invention at both of its ends. Railcar 188 may also be a locomotive in other embodiments. It is both a rail vehicle and two- or
- Multi-rail vehicles affected by the invention.
- the invention also relates generally to track-bound vehicles, even if the term rail is an uncommon term in these contexts.
- FIG. 8 shows a schematic representation of a rail traffic system according to the invention in a preferred embodiment. If reference symbols are used which are identical to those of one of the preceding figures, they describe identical features. The description in the respective figure then also applies to FIG. 8.
- the subfigures 8a to d show identical features in different states, so that not all the reference symbols are used consistently in each subfigure.
- FIG. 8a shows a first schematically indicated rail vehicle 190 and a second rail vehicle 192 according to the invention. For simplification only one axle 194 with two wheels 132, 196 is shown.
- the rail vehicles 190, 192 each comprise a central buffer coupling 146 according to the invention, which are engaged with one another in FIG. 8a.
- the coupled rail vehicles 190, 192 are located immediately in front of a rail switch 144 according to the invention, comprising a tongue device 130 according to the invention with two switch blades 88, 90 according to the invention and one associated stock rail 12, 14 each.
- the rail switch 144 further includes a
- Turnout 198 according to the invention in a neutral position, as already described in Figure 1.
- the control mechanism 62 is set (see FIG. 1) in such a way that an actuation of actuating elements 18, 22 results in a deflection of the actuating elements
- Control mechanism 62 upwards (analogously, this corresponds to a deflection to the left in Figure 1) has the consequence.
- the switch blades 88, 90 are in each case on the associated stock rail 12, 14 at.
- Figure 8d shows different track patterns behind the rail switch 144. The first
- Rail vehicle 190 is to follow in FIG. 8a the lane course shown in FIG. 8d above, and the second rail vehicle 192 is to follow in FIG. 8a the lane course shown in FIG. 8d below.
- FIG. 8b shows a first step of a setting operation of the rail switch 144.
- the first rail vehicle 190 with its wheels 132, 196 has run over the adjusting elements 18, 22 and, by comparison with the state of FIG. 8a, by approximately 180 ° in the direction the respective stock rail 12, 14 twisted. A resulting peripheral force has over one
- the first rail vehicle 190 is already partially with the wheel 196 on the
- Tongue tip 104 so that, although the first rail vehicle 190 has already passed the adjusting elements 18, 22, it is held in position.
- the spacing between the actuating elements 18, 22 and the tongue tips 104, 105 is designed accordingly.
- the torsion springs 58, 59 of the transfer drive 198 which is not shown in FIG. 8b, move the actuating elements 18, 22 back into the initial state of FIG. 8a.
- the control mechanism 62 is set in preparation for a next step by an external control not shown here (see Figure 1) that pressing the actuators 18, 22 in the next step a
- This step is shown in FIG. 8c as a second step of the parking operation of the rail switch 144.
- the second rail vehicle 192 with its wheels 132, 196 has run over and rotated the adjusting elements 18, 22. Due to the differently adjusted control mechanism 62, this has moved the switch tongue 90 downwards again in FIG. 8c and also deflected the switch tongue 88 downwards, so that, analogously to the state shown in FIG. 8b, different track patterns are also partially represented by the switch tongue 88.
- the track profiles are analogous to those described in FIG. 8b
- Step now maintained by the wheels 132, 196 of the second rail vehicle 192.
- the preceding first rail vehicle 190 guides the switch blades 88, 90 in accordance with the track pattern used by it with its wheels 132, 196.
- the rail vehicles 190, 192 thus follow different track patterns. This process is shown in more detail in FIG. 8d. Since the rail vehicles 190, 192 separate from one another in their respective tracks, but these are rigidly connected to the center buffer clutches 146, an offset d, which constitutes a deflection 172 of the
- Central buffer couplings 146 causes. As described for example in FIG. 5, a sufficiently large deflection 172 causes one of the levers 160 to strike against a stop 164 assigned to it. According to the description of FIG. 5, the central buffer couplings 146 and the first and second rail vehicles 190, 192 are uncoupled.
