The trailer tow-bar comprises a tow-hook (4) which can swivel from a storage position in a housing (2) to a position of use. A manual or electrical drive (5) cooperates with a bearing (9) on the inner end of the tow-bar and an adapter (10a, 10b) connected ...

The coupling has a ball rod on the vehicle pivotable between a locked rest position and a locked operating position with a coupling ball on its free end and an axially movable, resettable locking bolt (11) near the bearing ball end that interacts with a ra...

A drive mechanism (10) swivels a bar (5) with a spherical end on bearings fixed on a vehicle by intermediate switching of a planetary gear system (11) from a locked inactive position into a locked operating position and vice versa. On its free end away fro...

The trailer coupling has positive connection elements (270,280) on a bearing part (10) and on a bearing head (32). The bearing head is moveable relative to the bearing part in a direction at right angles to a pivot direction, to move the connection element...

The coupling (10) features a ball (12) supported by a neck (14) with a cranked end (16) and a lower end pivotable in a bearing (22). The projection of the central axis (70) of the ball on the vertical longitudinal plane (60) rotates through at least 80 deg...

A bearing part forms part of a road vehicle trailer coupling and is fixed to the towing vehicle. On it is located a pivot part with a ball throat and a coupling ball, the latter being pivotable relatively to the bearing part around an axis between a rest p...

The rotary bearing part (7) is able to swivel about a swivel axis (11) aligned at right angles to the transverse plane between a raised position and an incline position and in a second section is swivelled from the raised to the incline position so that th...
