FIELD: transport.
SUBSTANCE: invention relates to automotive industry. This system comprises hydraulic rudder engaged with hydraulic cylinders. Hydraulic rudder is engaged with frame turn hydraulic cylinders via frame alignment stabilizer including signalling hydraulic cylinder. Rod is connected with pin with centring spring contracted to threshold force and arranged between fixed and moving stops. Hydraulic pressure control valve is communicated with frame turn hydraulic cylinders. Tractor axle beam is engaged with frame by hinge located sideways of the front frame, opposite the turn hydraulic cylinder. Chamber of said cylinder are communicated with hydraulic rudder control channels parallel with signalling hydraulic cylinder. Proposed method consists in turning the rudder through small angle about vertical hinge to turn the axle beam. For deep-lunged torque at the end of working run rudder is turned to turn tractor frames.
EFFECT: better controllability.
