ABSTRACT:
A new and improved anti-jackknife apparatus for tractor to trailer connections includes a fifth wheel assembly connected to a tractor and a pair of locking pin assemblies connected to the fifth wheel assembly. Each of the locking pin assemblies includes an extensible and retractable lock pin. A control assembly is connected to the pair of locking pin assemblies. The control assembly is capable of being controlled by a first control signal in response to actuation of tractor brakes and is capable of being controlled by a second control signal in response to manual actuation of a bypass switch assembly by a tractor driver. A plate is connected to a trailer such that the trailer plate encircles a kingpin extending downward from the trailer. The trailer plate includes a pair of partially-ring-shaped slots adapted to receive the lock pins of the locking pin assemblies when the lock pins are in an extended position. The partially-ring-shaped slots are of a predetermined size and are oriented on the trailer such that when the lock pins of the locking pin assemblies are in engagement with respective ends of the partially-ring-shaped slots, a longitudinal axis of the trailer is oriented no greater than an acute angle of rotation either clockwise or counterclockwise from a longitudinal axis of the tractor. The acute angle of rotation between the longitudinal axis of the trailer and the longitudinal axis of the tractor is no greater than fifteen degrees.
