ABSTRACT:
Two members of a vehicle coupling are respectively connected to a tractor and a trailer. The member connected to the tractor comprises an "A"-frame which is pivotable about a horizontal transverse axis disposed between the front and rear axles of the tractor below the plane defined by the axes of these axles. A first bearing journalled on a first spindle projecting from the upper end of the A-frame carries, on its opposite sides, two diametrically aligned bearings which receive second spindles secured to connecting means for connecting the two members of the coupling. When the members are connected, the axes of the first and second spindles extend horizontally and vertically and define a plane which is perpendicular to the horizontal transverse axis of the connection between the A-frame and the tractor and the bearings mounted on the first and second spindles accommodate rolling and yawing movement between the members.
