IMPROVING THE RELIABILITY AND SIMPLIFICATION OF CONTROL SYSTEMS FOR HYDRAULIC DRIVES OF AGRICULTURAL MACHINES
Based on the definition of a power drive hydraulic and electric drives are analyzed. It was revealed that the control systems of the electric drive and the hydraulic drive are fundamentally similar, only the electric drive control system controls the flow of electric energy, and the hydraulic drive control system controls the flow of hydraulic energy. Obviously, therefore, the hydraulic drive control system must be built based on the principles of more advanced electric drive control systems. One of the ways to solve this problem can be the transition, by analogy with the electric drive, to the valve control system for hydraulic drives. Naturally, this requires the development of a hydraulic valve design that must meet all these requirements. The existing hydraulic distributor type 2/2 cannot yet meet these requirements. What the principle of using hydraulic valves can give is shown by the example of the hydraulic circuit of the BELARUS-2522V / 2522DV / 3022V / 3022DV agricultural tractor.
