Trailer coupling

Abstract

In order to improve a trailer coupling, comprising a ball neck, which is movable between a working position and a rest position and has a pivot bearing body arranged at a first end and a coupling ball arranged at a second end, a pivot unit, which is arranged fixed to a vehicle and by means of which the pivot bearing body is pivotal for the purpose of performing a pivotal movement about a pivot axis between a working position and a rest position, wherein the pivot unit comprises a pivot bearing unit fixed to the vehicle and a rotation-blocking device for blocking a pivotal movement of the pivot bearing body about the pivot axis, at least in the working position, the improvement being such that this susceptibility to faults in a trailer coupling of the kind mentioned in the introduction is avoided, it is proposed that a pivot control unit should be integrated within the pivot unit.
