  "textContent": "A semi-trailer truck with a tractor and a semitrailer having a kingpin, wherein the tractor includes a fifth wheel coupling with a coupling plate, a closure for the king pin, an actuating mechanism for actuating the closure, and a cylinder-piston assembly engaging the actuating mechanism for moving the actuating mechanism. The tractor further includes a compressed air supply line to which the cylinder-piston assembly can be connected directly by a quick coupling. The quick coupling is formed from a first and a compatible second coupling element. The semitrailer includes a compressed air system, wherein the cylinder-piston assembly and the compressed air system of the semitrailer are each assigned the identical first coupling element, and the compressed air supply line is assigned the compatible second coupling element.",
