摘要

The invention relates to a sliding device for a fifth wheel. The aim of the invention is to reduce the overall weight of the system consisting of vehicle frame/slide system and also to simplify its assembly. To this end, the base frame is provided with two longitudinally extending angular profiles that are linked with each other by means of two detachable and slidably mounted tie-bars. Every angular profile comprises retaining means that interact with second retaining means of the upper part in such a manner that the upper part can be displaced relative to the base frame in the longitudinal and the transverse direction. The invention device does not require an auxiliary frame that is conventionally used.
