Abstract
Coupling arrangement intended for mounting on a towing vehicle provided with parallel frame side members and for coupling the towing vehicle detachably to a towed vehicle such as a trailer. The arrangement incorporates a fifth wheel which is tiltably connected to the frame side members by tilt pivot mountings in the regions of the frame side members. Each tilt pivot mounting incorporates a vertically upright support device made integrally and intended to be fastened directly by means of a lower fastening portion to the outside of a vertical web portion of the respective adjacent frame side member. The support device has in its upper end a bearing sleeve in which a hingepin mounted on the underside of the fifth wheel is supported. Each support device incorporates at least two supporting legs which extend between and converge from the fastening portion to the bearing sleeve and a central support leg between the fastening portion and the bearing sleeve.
