  • the automatic changeover 13 is used to set the functional positions "long” or “short".
  • the shortening is realized by the spacer 19, which is between the coupling head 4 and the coupling arm 10.
  • the functional sequence can be described as follows: When the vehicles 3 are pressed on, the coupling head 4 is pressed back onto the coupling arm 10 and opens the space for the spacer 19. It can now occur.
  • the automatic pull coupling 1 is thus brought into the "short" functional position, as shown in FIG. 4c.
  • To unlock the spacer 19 is pulled out via the pin D via the actuator 2.
  • the bolt 15 is withdrawn from the profile.
  • the spacer 19 is pulled out via the locking lever 18 and the slide 24 and pushed back by the locking lever 18 of the locking bar 15 after the Latch lever 18 has raised the latch pawl 16.
  • the coupling head 4 is by the Support advanced to the long position. An unwanted reconnection is not more possible because the couplings are already separated too far. After the full Separation then turns the pedal further and presses the latch 16 and the latch 15 back. Both clutches are then in the dome-ready position again.
