FIELD: machine building.
SUBSTANCE: invention relates to transport engineering, namely to trailers hitch mechanisms. Multifunctional trailer hitch mechanism comprises coupling element, rigidly coupled with crossbar provided with thrusts and locking device, symmetrically arranged relative to tie-rod longitudinal axis, each of which is made in form of hydraulic cylinder. Tie-rods first ends are articulated with crossbar, and second are with trailer front axle. Device is additionally equipped with electronic control unit, hydraulic cylinders piston and rod cavities electric windings, hydraulic cylinders windings control busbar, hydraulic cylinders piston and rod cavities shielding. In device hydraulic system magnetorheological fluid is used as working liquid instead of oil.
EFFECT: enabling increase in trailer train flotation ability due to its components separate starting and matching of truck wheels tracks and trailer at curvilinear motion, increase in trailer train road-holding ability during braking, hitching element reduced wear, device higher automation and faster operation.
