摘要

The invention relates CONTROL STEERING WHEEL OF A BISEL interposed between a tractor and a semitrailer. BARS STEERING CONTROL (51,52,53,54) BEVEL WHEELS ARE DRIVEN CONTROLLED POWER SYSTEM FROM A CONTROL SECTION DETECTING MOVEMENT DIRECTION WHEELS (13) TRACTOR . The control section BIELITA CONSISTS OF A CONTROL (38) rotating freely on a shaft (39) and is rotated by a transmission (31,36) linked to the cam (28) STEERING WHEEL (13 ) TRACTOR. BIELITA ROTATION CONTROL (38) selectively controls a hydraulic distributor (42) which actuates a double-action jack (45,46) linked to a connecting rod (50) CONTROL OF STEERING RODS (51.52, 53.54). The invention is applied in pulling semitrailers porterage BY HEAVY bezel.
