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, comprises a drive unit, at least one hydraulic curcuit with a hydraulic pump driven by the drive unit, 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 and/or at least one hydraulic circuit, wherein the hydraulic pump/motor assembly can be operated in a charging operating mode by the drive unit and/or at least one hydraulic circuit as a pump to charge at least one pressure fluid reservoir, and be driven in a 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 is operated in a recirculation operating mode as a pump to convey fluid out of a fluid reservoir and into a fluid reservoir.
