Fifth wheel couplings are used to form an articulated connection between a fifth wheel tractor and a semitrailer. They usually have a fifth wheel coupling plate which is fixed on the fifth wheel tractor by bearing elements (5, 10) and which has a V-shaped recess (2) with a central cavity (3) and a lock for receiving and locking in a kingpin which is mounted on the semitrailer in the middle of an upper plate in such a way that it is fixed. The fifth wheel coupling plate also has an anti-attrition sliding layer (4a, b) on the side facing the upper plate. The inventive fifth wheel coupling plate consists of two separate components which can be mechanically interconnected, i.e. an upper bearing component (12a) which interacts with the upper plate and which is provided with the sliding layer (4a, b), and a lower supporting component (1b) on which the central recess (3) is provided with the engaging lock.
