Torque regulator for gearing system - calculates pressure control signals for hydrostatic pump and hydrostatic motor using computer

摘要

The torque regulating system has a computer to control the gearing's output torque. The speeds of the two hydrostats (one acting as pump/ and the other acting as motor and between them the bearing) are input into the computer. The positions of the displacing devices (that influence the pressure difference in the two hydrostats), the difference pressure and the wanted torque are also input into the computer. The computer determines the desired pressure. The difference between the prevailing pressure difference and the determined pressure is formed and used to control a pressure regulator.
