Title:
HYDROSTATIC DRIVE SYSTEM
Document Type and Number:
Japanese Patent JP2013019414
Kind Code:
A
Abstract:

To reduce high adjustment costs for adapting a hydraulic return signal in a conventional technique and to enhance dynamic properties of consuming machine motion as well as the dynamic performance of a drive system.

The hydrostatic drive system includes a pumping volume adjustable pump which supplies a pressure medium to at least one consuming machine. A pumping volume adjustment device of the pump is controlled in a direction of increasing the pumping volume by use of a set signal, and also controlled in a direction of reducing the pumping volume in relation to a hydraulic return signal which detects an excessively pumped volume flow of the pump. In order to obtain the return signal, the system further includes a circulating pressure compensator which generates the hydraulic return signal at a return signal generation position. A pressure limiting device 50 is disposed in a return signal conduit line 32 for guiding the hydraulic return signal, and/or an interruption device 70 for the hydraulic return signal is provided therein.
