  • Corresponding recesses are provided on the hydraulic coupling unit 18 of the main coupling part 1, into which the guide pins 40 can engage when the hydraulic coupling unit 18 moves from the decoupling position 20 into the coupling position 21.
  • the illustrated embodiment provides that the hydraulic clutch unit 34 of the secondary clutch part 2 is elastically supported by means of a damping plate 37 made of rubber or plastic.
  • the hydraulic coupling unit 34 is in turn fastened to a bracket 48 of the secondary coupling part 2 via the damping plate 37.
  • the console 48 is rigidly connected to two plate-shaped sections of the secondary coupling part 2, which plate-shaped sections also have the forks 46.
  • the hydraulic coupling unit 34 of the secondary clutch part 2 has five hydraulic line connections 38 which are in fluidic connection with the hydraulic clutches 35 of the secondary clutch part 2 and point to the reference plane 26, cf. Fig. 4 .
  • Hydraulic lines (not shown) can be connected to the hydraulic line connections 38 of the secondary clutch part 2 in order to supply hydraulic drives of the attachment part with hydraulic oil.
  • hydraulic line connections 38 are also provided on the main coupling part 1, which are in fluidic connection with the hydraulic couplings 19 and serve to connect hydraulic lines in order to be able to provide hydraulic oil, cf. Fig. 5 .
  • the hydraulic coupling unit 34 of the secondary clutch part 2 has two hydraulic high-flow line connections 39 in the illustrated embodiment, which are in fluidic connection with two hydraulic clutches 35 of the secondary clutch part 2 and essentially into the second direction 28 point.
  • the hydraulic high-flow line connections 39 are passed through the damping plate 37 and through the console 48.
  • corresponding recesses or bushings for the hydraulic high-flow line connections 39 are provided in the damping plate 37 and the console 48.
  • the direction of flow of the hydraulic oil is deflected downwards or pointing to the reference plane 26 or against the normal direction 23 and the third direction 29. In this way, hydraulic lines can also be connected from "below" to the hydraulic high-flow line connections 39.
  • the secondary clutch part 2 has a protective plate 45.
