Connector assembly for fifth wheel

摘要

The plug connection assembly (11) includes a plug connector upper section (9) in the king pin of the semi-trailer, with a plug connection lower section (7) in the saddle coupling plate (2) of the tractor vehicle. The upper- (9) and lower sections (7) each include plug-connectable electrical- and pneumatic or hydraulic lines. These are constructed in the form of annular plug bushes and/or couplings. In novel design, the plug connector assembly (11) rotates on a separate bearing assembly (12).
