Abstract
In order for a trailer coupling comprising a ball neck which can be moved between an operating position and a rest position and has a coupling ball, also comprising a vehicle-mounted pivot-bearing unit, in which the pivot-bearing body is accommodated such that it can be pivoted about a pivot axis, and further comprising a rotation-blocking device which can be driven by a drive, to be improved such that it can absorb, in constructional terms, the highest possible load moments, it is proposed that the rotation-blocking device has at least one rotation-blocking body, that the rotation-blocking body can be engaged with, and disengaged from, a holder by movement in a guide direction, that there is provided an actuating body which has a pressure-exerting surface and the movement of which allows the at least one rotation-blocking body to be moved and acted on, and that the drive is an actuating drive by means of which the actuating body can be moved between at least one rotation-blocking position and a freewheeling position.
