摘要：
A fifth wheel for coupling a tractor to a trailer carrying a kingpin. The fifth wheel comprises a mounting structure adapted to be mounted to the tractor and a fifth wheel plate mounted to the mounting structure and a top bearing surface rotateable relative to the mounting structure about an axis normal to the top bearing surface in order to minimize the friction between the top bearing surface of the fifth wheel plate and the trailer.
