DRIVE SYSTEM, IN PARTICULAR FOR A SELF-PROPELLED CONSTRUCTION MACHINE, IN PARTICULAR A SOIL COMPACTOR
A drive system, in particular for a self-propelled construction machine, in particular a soil compactor, comprising an internal combustion engine comprising a drive unit, at least one hydraulic circuit with a hydraulic pump that can be driven by the drive unit, as well as a hydraulic-drive support unit with a hydraulic pump/motor assembly and at least one pressure fluid reservoir, wherein the hydraulic pump/motor assembly is or can be drivingly coupled with the drive unit or/and at least one hydraulic circuit, wherein the hydraulic pump/motor assembly can be operated in a charging operating mode by the drive unit or/and at least one hydraulic circuit as a pump to charge at least one pressure fluid reservoir and be operated in an drive support operating mode as a motor to provide a drive support torque for the hydraulic pump of at least one hydraulic circuit, characterized in that the hydraulic pump/motor assembly can be operated in a recirculation operating mode as a motor to start the drive unit.
