LUBRICATION SYSTEM FOR A FIFTH WHEEL TRACTION COUPLING OF A SEMI TRAILER TRACTION ENGINE

摘要

The invention concerns a lubricating system for a fifth-wheel traction coupling (1) of a towing vehicle (2), comprising a coupling plate (3), the upper side (4) of which has at least one grease discharge aperture (5) which is connected to a lubricating device (7) via a supply line (6) fixed to the coupling plate (3). The invention addresses the problem of developing a lubricating system for towing vehicles which permits automatic lubrication irrespective of whether a central lubricating system is provided. The invention solves the problem using a lubricating system in which the lubricating device (7) is associated with the fifth-wheel traction coupling (1) and is arranged directly on the fifth-wheel traction coupling (1) or in the vicinity of the fifth-wheel traction coupling (1).
