Method for determining a control limit of a valve, hydraulic machine with the valve and hydrostatic travel drive with the hydraulic machine

摘要

A method is disclosed for determining at least one control limit of an electrically controllable first pressure reducing valve as a function of a first control current, for which purpose a driven hydraulic machine is provided, the displacement volume of which is adjustable by a center-centered actuator with opposing pressure surfaces, a first of which is dependent on the first pressure reducing valve of the first control current can be acted upon by the first control pressure, the high pressure or a correlated operating variable of the hydraulic machine being detected. Furthermore, a hydraulic machine with such a pressure reducing valve and a hydrostatic travel drive with the hydraulic machine and a hydraulic motor that can be driven are disclosed.
