Abstract
A fifth-wheel coupling for releasably coupling a fifth-wheel tractor () to a semitrailer (). A kingpin on s semitrailer can be brought into engagement with a fifth-wheel plate on the fifth-wheel tractor. A first insertion coupling part is arranged on the fifth-wheel plate in such a way that it can be moved by means of a lifting device from a decoupled, retracted idle position into a protruding coupling position. A centering unit, e.g., conical centering pins, is provided on the lifting device which centers the relative position of the first insertion coupling part in the decoupled position. The centering is mounted floating against the force of springs on the fifth-wheel plate. The centering is released in the coupling position after the coupling process. After coupling the semitrailer to the fifth-wheel tractor, during insertion the first plug-in coupling part can easily move laterally for safe insertion due to the released centering, in the case of any small misalignments between the fifth-wheel plate and the kingpin of the semitrailer. After coupling, an undesirable relative movement between the two plug-in coupling parts is prevented, thus minimizing wear.
