Drive system, in particular for a self-propelled construction machine, in particular soil compactor

A drive system (10), in particular for a self-propelled construction machine, in particular soil compactor, comprising a drive unit (26), at least one hydraulic circuit (30, 34) with a hydraulic pump (32, 36) drivable by the drive unit (22), and a hydraulic drive assistance unit (38) with a hydraulic pump/motor assembly (40) and at least one pressure fluid accumulator (42), wherein the hydraulic pump/motor assembly (40) is drivingly coupled or couplable to the drive unit (26) and/or at least one hydraulic circuit (30, 34), wherein the hydraulic pump/motor assembly (40) in a charging operating state can be operated by the drive unit (26) and/or at least one hydraulic circuit (30, 34) as a pump for charging at least one pressure fluid accumulator (42) and in a drive assistance operating state can be operated as a motor for providing drive assistance torque for the hydraulic pump (32, 36) of at least one hydraulic circuit (30, 34), is characterized in that a maximum drive torque providable by the drive unit (26) is smaller than a maximum required torque to be applied for operating at least one hydraulic circuit (30, 34).
