Abstract

Marine hybrid drive unit (100) with an electric motor (2) and a transmission (3). The transmission (3) comprises an input shaft (4), an output shaft (5) and a pressure actuated transmission clutch (6) to selectively connect the input shaft (4) to the output shaft (5). The input shaft (4) can selectively be driven solely by a combustion engine (1), solely by the electric motor (2) or by the combustion engine (1) and the electric motor (2) simultaneously. The transmission (3) further comprises a main oil pump (7), which is driven by the input shaft (4) to provide oil pressure for actuating the pressure actuated transmission clutch (6). The marine hybrid drive unit further comprises an auxiliary oil pump (8) for providing oil pressure to the pressure actuated transmission clutch (6) during operation in a low-speed range.A method for driving such a marine hybrid drive unit (100).
