Abstract
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 ( ) and which has a V-shaped recess ( ) with a central cavity ( ) 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 ( ) 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 ( ) which interacts with the upper plate and which is provided with the sliding layer ( ), and a lower supporting component ( ) on which the central recess ( ) is provided with the engaging lock.
