A hydraulic actuator of displacement of a vehicle has four hydraulic engines of displacement, three flow dividers, four-line control valves, check valves, a pump, a pressure valve, where the outlets of the first flow divider are connected to the inlets of second and third flow dividers, which through four-line control valves are connected to hydraulic lines of high, low pressure of hydraulic engines and a hydraulic tank. The hydraulic actuator additionally contains two-line and three-line hydraulic valves, the inlets of second and third flow dividers through two-line control valves and check valves are connected to the inlets of four-line control valves, the inlet of the first flow divider through a two-line control valve and check valves is connected to its first and second outlets, and in the hydraulic line between second outlet of the first flow divider and inlet of the second flow divider a three-line control valve is introduced, which is connected to the drain line, in the case the four-line control valves connected to the third flow divider are three-position with an open center. |
