ABSTRACT:
A fifth wheel coupling includes a receiver that is suspended from the frame of a towing vehicle by a linkage mechanism to permit limited relative longitudinal and vertical displacement of the towing vehicle and a towed vehicle. The receiver is mounted on a wishbone bracket that straddles the frame of the towing vehicle, and swinging linkage members couple the wishbone bracket to the frame. Initial forward movement of the tractor produces rotation of the linkage members with respect to the frame without producing forward movement of the towed vehicle. The rotation of the linkage members slightly elevates the receiver, whereafter the towed vehicle and receiver follow the towing vehicle in a swinging motion as the effects of gravity overcome the rolling resistance of the towed vehicle and its load.
