ABSTRACT:
A truck coupling arrangement which couples the front of a trailer to the rear of a tractor for movement about a pivot axis locates the pivot axis back toward the rear of the tractor while at the same time maintaining the weight of the trailer and the resulting downward force on the tractor well forward and essentially centered between the dual axle rear wheels of the tractor. This has the effect of delaying the inward movement of the front of the trailer during turning of the truck, thereby improving the tracking of the trailer. The increased turning radius of the trailer reduces the need to steer the truck widely through turns in order to avoid objects at the inside of the turn. In a specific embodiment of a truck coupling arrangement, a bearing plate at the front end of a bracket pivotally mounted on the rear end of the tractor is non-rotatably coupled to the front of the trailer by a plurality of pins so that pivoting of the trailer relative to the tractor occurs at the rear end of the tractor.
