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.

Fifth wheel coupling

A vehicle frame which enables a lowering of the saddle coupling with improved stability for this, and recesses at the upper side of the lengthwise girders of the vehicle frame extending across the entire width of the frame are proposed. The saddle coupling is fastenably secured to the lengthwise girders.

Vehicle frame

A fifth wheel is described with a coupling plate having elements for fastening to the vehicle frame. It is supposed to facilitate the mounting on the vehicle frame, while it should be possible to equalize manufacturing tolerances of the frame in simple fashion. The fastening elements attach to pivot pins, which are detachably arranged on the fifth wheel and project outward to the side beyond the coupling plate.
