Abstract
The invention concerns a lubricating system for a fifth-wheel traction coupling of a towing vehicle, comprising a coupling plate, the upper side of which has at least one grease discharge aperture which is connected to a lubricating device via a supply line fixed to the coupling plate. 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 is associated with the fifth-wheel traction coupling and is arranged directly on the fifth-wheel traction coupling or in the vicinity of the fifth-wheel traction coupling.
