A coupling device for supply lines is used in particular for conveying media from a tractor to a semi-trailer (11) or vice versa. The tractor and the semi-trailer (11) can be coupled and uncoupled by means of a coupling unit (10), which comprises a fifth wheel coupling (15) on the tractor and a support element (22′) with a king pin (21) on the semi-trailer (11). Below the fifth wheel coupling (15) and below the king pin (21), there is at least one coupling block (30, 31) each, the coupling blocks each being provided with a plurality of connector elements (37, 38, 77, 78) for connecting the supply lines (33, 34, 35, 36). A rotary element (20) disposed in the support element is provided, to which rotary element the at least one coupling block (30, 31) and a centering device (25) are fastened. During the coupling, the centering device interacts with centering means on the fifth wheel coupling (15) such that the coupling blocks (30, 31) can be aligned with each other and consequently can be connected to each other. The supply lines (35, 36) leading away from the coupling block (31) on the semi-trailer (11) are led, by connecting means (23, 24) in the rotary element (20), to the supply lines (35′, 36′) disposed in the semi-trailer (11). With said coupling device for said supply lines in particular for exchanging said media, a very compact construction has been achieved which allows the supply lines to be automatically connected when the fifth wheel coupling is coupled to the king pin.
Coupling device for supply lines, in particular for conveying media from a tractor to a semi-trailer (11) or vice-versa, which can be coupled or uncoupled by means of a coupling unit (10), which comprises a fifth-wheel coupling (15) on the tractor and a support element (22′) with a kingpin (21) on the semi-trailer (11), characterized in that arranged on the under side of the fifth-wheel coupling (15) and the king pin (21) and/or next to them is at least one coupling block (30, 31), which in each case are provided with preferably a plurality of connector elements (37, 38, 77, 78) for connecting the supply lines (33, 34, 35, 36), wherein a rotary element (20) is provided arranged in the support element (22′), secured to which are the at least one coupling block (30, 31) and a centering device (25), which during coupling interact with centering means on the fifth-wheel coupling (15) in such a way that the coupling blocks (30, 31) can be aligned with one another and subsequently connected, wherein the supply lines (35, 36) leading away from the coupling block (31) on the semi-trailer (11) are guided through connecting means (23, 24) in the rotary element (20) to the supply lines (35′, 36′) arranged in the semi-trailer (11).
