Abstract
The invention related to a hydrostatic drive comprising a hydraulic pump (3) which is driven by a drive machine (2) and pumps into at least one first working line(4), and a pressure line (18) in which a feed quantity dependent on the speed of the drive machine (2) flows. When a differential pressure value in the pressure line (18) is exceeded, the pressure means can be extracted from the first working line (4).
Claims9
Hydrostatic drive having a hydraulic pump, which is driven by a driving machine and delivers into at least a first work line, and having a pressure line, in which there flows a feed quantity that is dependent on the rotational speed of the driving machine, wherein
- the pressure medium can be removed from the first work line, into which pressure medium is delivered by the hydraulic motor operated as a pump in an overrun mode, if a differential pressure limiting value is exceeded in the pressure line, such that a pressure medium partial flow is forwarded in the direction of the hydraulic pump.
