Substantiating of Rational Law of Hydrostatic Drive Control Parameters While Accelerating of Wheeled Tractors with Hydrostatic and Mechanical Transmission

The paper explains a process to determine rational laws of change in parameters to control hydraulic units of hydrostatic drive while accelerating wheeled tractors with hydrostatic and mechanical transmissions operating according “input differential” and “output differential”schemes. The paper substantiates application of rational laws of change in parameters to control hydromachines by determining power distribution within hydraulic and mechanical branches of hydrostatic and mechanical transmissions produced according to “input differential” and “output differential” schemes. Decrease in a zone of power circulation within hydrostatic and mechanical transmissions with output differential has been determined while applying rational laws of changes in control parameters.
