摘要： A drive train (1) includes an internal combustion engine (2) and working hydraulics (4) having at least one hydraulic pump (7). When operated as a pump, the hydraulic pump (7) sucks hydraulic fluid from a tank (9) and delivers into a delivery line (10) that leads to the working hydraulics (4). When operated as a motor, the hydraulic pump (7) is supplied with hydraulic fluid from a hydraulic accumulator (25). The drive train (1) has a charge pump (20) to supply a charging circuit (23). The charge pump (20), when operated as a pump, sucks hydraulic fluid out of the tank (9) and delivers into a charge pressure line (22) that leads to a charging circuit (23), and the charge pump (20) when operated as a motor is supplied with hydraulic fluid from the hydraulic accumulator (25).

摘要： A variable displacement hydrostatic power unit (7) is in a drive connection with an internal combustion engine (2). When operated as a pump, the power unit (7) delivers hydraulic fluid to at least one consumer (V). When operated as a motor, the power unit (7) is a hydraulic starter for the internal combustion engine (2) and is supplied with hydraulic fluid from a hydraulic accumulator (25). The displacement volume of the power unit (7) is set by a displacement volume control device (50) actuated by a positioning device (52). The displacement volume control device (50) is displaced into a position with maximum displacement volume by a corresponding actuation of the positioning device (52) chronologically prior to the shutoff of the internal combustion engine (2). A securing device (60) holds the displacement volume control device (50) in the maximum displacement volume position when the internal combustion engine (2) is shut off.

摘要： A variable displacement hydrostatic power unit (7) is connected with an internal combustion engine (2). The power unit (7) operates as a pump to deliver hydraulic fluid to at least one consumer (V) and operates as a motor as a hydraulic starter for the internal combustion engine (2). Hydraulic fluid from a hydraulic accumulator (25) is supplied to the power unit (7) operated as a motor. The power unit (7) includes a spring device (55) which, when the internal combustion engine (2) is shut off, actuates a displacement volume control device (50) into a position with the maximum displacement volume. When the power unit (7) is actuated with hydraulic fluid from the hydraulic accumulator (25), the internal combustion engine (7) is immediately started by the power unit (7) without the need for an immediately preceding adjustment of the displacement volume control device (50) of the power unit (7).

A shutoff valve (30) is located in the connecting line (26). The shutoff valve (30) is a check valve (31) that opens automatically and as a function of the pressure to allow a flow to the hydraulic accumulator (25). A pressure relief valve (32) is operatively associated with the connecting line (26) between the shutoff valve (30) and the hydraulic accumulator (25).
