ABSTRACT:
A system including an anti-jackknifing abutment apparatus (FIGS. 1-4, 7, 8) an electrical (FIG. 5) and hydraulic (FIG. 6) controls provides system control which controls limited relative angular movement between an articulated tractor 10 and trailer 20. An engagement driver in the form of cylinder 36 mounted within a rigid frame 23 is mounted by a mounting bar 25 to a forward beam member 22 of the trailer 20 for moving a abutment element 28, 128 into and out of an engagement zone within the longitudinal V-slot 17 of the fifth wheel 14. The abutment element in position on a rotational swing of the articulated vehicle is contacted by ears 18 of the V-slot, where due to the structure of the apparatus, the further rotational movement may be arrested or controlled to permit adjustment of the rotational limit of further angular movement under control of the driver. The system can be adjusted and controlled to permit adaption of the moving vehicle to various road and rig movement conditions, acting to prevent dangerous jackknifing from occurring.
