Hydrostatic drive system for mobile work machine, particularly industrial truck, has working hydraulic system or hydraulic steering system, which are supplied from pump adjustable in industrial truck, formed as load sensing pump

摘要

The hydrostatic drive system (1) has a working hydraulic system or a hydraulic steering system (5), which is supplied from a pump (2) adjustable in the industrial truck, formed as load-sensing-pump. The load-sensing-pump is drivingly connected with an internal combustion engine (3) and has a hydraulic fan drive (6) for producing a cooling air stream for a heat exchanger for cooling the pressurizing medium of the drive system.
