摘要:
A drive system for hydraulically driven working mechanisms of a working machine includes an axial piston pump, the pump capacity and flow direction of which is varied by changing the pivot angle of the axial piston pump. The drive system includes a hydraulic motor connected via a line to the axial piston pump and drivably connected to the working mechanisms, a control unit operated to set the pump capacity of the axial piston pump to zero and a control valve arrangement that is actuated by the control unit to actuate a limiting device such that the pivot angle of the axial piston pump can be mechanically set to zero degrees (0°).
