DRIVE ARRANGEMENT WITH OPEN LOOP HYDRAULIC MECHANISM OPERABLE AS A PUMP OR A MOTOR

摘要

A drive arrangement ( 10) suitable for driving a final drive (20) comprises a first drive means (30) and a power-splitting gear arrangement (40). A first hydraulic mechanism (100) is operable either as a pump or a motor. The first hydraulic mechanism (100) is capable of being driven from the first drive means (30) or from the final drive (20) or both concurrently, acting through the gear arrangement (40). The final drive (20) is drivable through the gear arrangement (40) from the first drive means (30) or the first hydraulic mechanism (100) or both concurrently.
