ABSTRACT:
A hydrostatic drive system is provided for a vehicle, in particular an industrial truck having a hydrostatic traction drive system (16), a hydraulic work system (20) and a hydraulic steering system (8). The drive system is compact and the energy utilization in the drive system is improved by providing a hydraulic pump (1) with an adjustable delivery volume working in an open circuit to supply the traction drive system (16), the hydraulic work system (20) and the steering system (8). In one configuration of the invention, there is at least one traction drive control valve (23) in the delivery line (5b) of the pump (1), whereby upstream of the traction drive control valve (23) in the delivery line (5b) of the pump (1) there is a priority valve (18) for the hydraulic work system (20), and upstream of the priority valve (18) of the hydraulic work system (20) there is a priority valve (6) for the steering system (8). In one embodiment of the invention, a feed line (11) of a feeder device (15) can be connected to the delivery line (5a) between the priority valve (6) of the hydraulic steering system (8) and the priority valve (18) of the hydraulic work system (20).
