Hydrostatic traversing gear control - uses pressure control valve for axial piston and displacement motor assemblies and influences high pressure regulator

摘要

The system has a pressure control valve (20) for the axial piston and displacement motor (2, 3) assemblies and its control piston. It is pressure loaded via a braking valve (4) so that when a preset pressure is exceeded it is displaced and influences the high pressure regulator (25). A bypass nozzle, which opens when pressure falls below a specified level, is provided for the high pressure regulator (25) and is connected to the reservoir (6). The pressure control valve has a set pressure of approx. uses 20 bars. USE/ADVANTAGE - The necessary torque for high speed climbing motion is made available.
