Trailer coupling with friction damper

摘要

The invention relates to a trailer coupling comprising a housing (1), one wall of which forms a first part-spherical coupling surface (4), a coupling element (8) which is movably mounted on the housing and which forms a second part-spherical coupling surface (7), a control lever (12) pivotally mounted on the housing with which the movable coupling element can be displaced between an open position, at an interval from the first coupling surface, and an engaging position close to the first coupling surface. At least one of the coupling surfaces carries friction material and resilient pre-loading means (19) are arranged for constraining the movable coupling element into the engaging position with a pre-loading towards the first coupling surface. The pre-loading means grip onto the control lever and the control lever transfers the pre-loading onto the movable coupling element.
