DRIVE SYSTEM, IN PARTICULAR FOR A SELF-PROPELLED CONSTRUCTION MACHINE, ESPECIALLY A SOIL COMPACTOR
A drive system, in particular for a self-propelled construction machine, especially a soil compactor, comprising a drive unit, at least one hydraulic circuit with a hydraulic pump drivable by the drive unit, as well as a hydraulic drive support unit with a hydraulic pump/motor assembly and at least one compressed fluid reservoir, wherein the hydraulic pump/motor assembly is, or can be, drivingly coupled to the drive unit and/or to at least one hydraulic circuit, wherein the hydraulic pump/motor assembly can be operated in a charging operating mode as a pump by means of the drive unit and/or by means of at least one hydraulic circuit for charging at least one compressed fluid reservoir, and which is drivable in a drive support state as a motor to provide a drive support torque for the hydraulic pump of at least one hydraulic circuit, is characterized in that a maximum drive torque provided by the drive unit is smaller than a maximum request torque to be applied for operating at least one hydraulic circuit.
