Abstract

A self-propelled compaction roller comprises a drive system having a drive assembly, a hydrostatic/mechanical transmission arrangement with a hydraulic pump, which can be driven by a primary drive of the drive assembly, and with a hydraulic motor, further having a supporting drive arrangement having a charging/driving unit and an energy storage unit, wherein the charging/driving unit can be operated in a charging mode for storing energy in the energy storage unit and can be operated in a supporting mode by withdrawing energy from the energy storage unit in order to provide a supporting torque, wherein the charging/driving unit is coupled to a power take-off of the drive assembly.
