SELF-PROPELLED COMPACTION ROLLER AND METHOD FOR OPERATING A SELF-PROPELLED COMPACTION ROLLER

摘要

A self-propelled compaction roller comprises a drive system (10) having a drive assembly (12), a hydrostatic/mechanical transmission arrangement (22) with a hydraulic pump (18), which can be driven by a primary drive (14) of the drive assembly (12), and with a hydraulic motor (20), further having a supporting drive arrangement (26) having a charging/driving unit (28) and an energy storage unit (42), wherein the charging/driving unit (28) can be operated in a charging mode for storing energy in the energy storage unit (42) and can be operated in a supporting mode by withdrawing energy from the energy storage unit (42) in order to provide a supporting torque, wherein the charging/driving unit (28) is coupled to a power take-off (44) of the drive assembly (12).
