Coupling device, agricultural vehicle and method for mechanical coupling and media supply between a carrier vehicle and a superstructure

Coupling device (1) for mechanical coupling and media supply between a carrier vehicle (41) and a superstructure (42), having a coupling mechanism (10) for establishing a mechanical coupling between the carrier vehicle (41) and the superstructure (42) and a media mechanism (20) for establishing a media supply between the carrier vehicle (41) and the superstructure (42) which are operatively connected with each another via an operating mechanism (30), wherein the coupling mechanism (10) is mounted so as to be moveable between at least one first coupling position at least partially forming the mechanical coupling and a release position releasing the mechanical coupling, wherein the media mechanism (20) is also mounted so as to be moveable between a supply position forming the media supply and a shut-off position shutting off the media supply,

• wherein
• the operating mechanism (30) has at least one guide means (31) for a forced guidance of the media mechanism (20) from the shut-off position into the supply position on a movement of the coupling mechanism (10) from the release position into the first coupling position,
• characterised in that
• in addition to the first coupling position the coupling mechanism (10) has a complete coupling position (Off:
• 5/6-10;
• 10/17-19;
• 18/13-15;
• FIG. 3b+3c),
• wherein in the first coupling position a mechanical coupling between the carrier vehicle and the superstructure is already established (Off:
• 3/16;
• 18/7-10), and
• wherein in the complete coupling position no relative movement between the carrier vehicle and the superstructure is possible (Off:
• 3/19;
• 10/26-29;
• 18/20-23).
