Control system for hydrostatic drive with electronic pressure measurement controls displacement pump and motor adjustment mechanisms depending on pump input, output speeds

摘要

The system has a digital computer unit (9) that produces two control signals (C,D) for adjustment mechanisms for a displacement pump and for a displacement motor based on the input and output revolution rates (A,B) of the pump (4) and computes the operating pressures in the working lines (7) of the hydrostatic drive based on the revolution rate and control signals.
