    摘要: A drive system (1) for a harvesting machine has a drive train (4) connected by a coupling device (5) with a drive motor (6). The drive train (4) has a hydrostatic transmission (10) with a variable displacement pump (11) and a hydraulic motor (12) connected in a closed circuit to the pump (11). The hydraulic motor (12) is connected to a feeder device (2). For quickly stopping the feeder device (2), the pump (11) is set to a displacement of zero by an electronic control system (15) and the feeder device (2) is braked by a pressure protection device (40). For a chopper device (3), the hydraulic motor (12) is cut off by the electronic control system (15). The drive train (4) is isolated from the drive motor (6) by uncoupling the coupling device (5) and the pump (11) is set to the maximum displacement volume.

    摘要: A hydrostatic power unit (2) comprises a variable displacement machine with a continuously variable displacement volume and is operated as a pump and motor and is in a drive connection with an internal combustion engine (3). When operated as a pump, the power unit sucks hydraulic fluid out of a tank (9) and delivers into a delivery side (P), and, when operated as a motor, functions as a hydraulic starter to start the internal combustion engine (3). When operated as a motor, the power unit is supplied with hydraulic fluid from a hydraulic accumulator (30). The displacement volume of the power unit (2) is set by a displacement volume control device (60) actuated by a positioning piston device (61) supplied with hydraulic fluid from a charging pressure circuit (23). The power unit (2) includes a supplemental positioning piston device (80) in an operative connection with the displacement volume control device (60) and which is actuated directly by the pressure present in the hydraulic accumulator (30). By means of a connection of the supplemental positioning piston device (80) with the hydraulic accumulator, the power unit (2) can be adjusted to increase the displacement volume to start the internal combustion engine (3).
