POWER-TRANSMISSION DEVICE AND HYBRID CONSTRUCTION EQUIPMENT PROVIDED THEREWITH

摘要

To be able to directly use engine power to power a hydraulic pump; and to perform electrical generation and motor assist efficiently. This hybrid construction equipment is provided with the following: an engine (14); a generator (15) that can generate electricity from power produced by the engine (14); a battery (19) that can store the electricity generated by the generator (15); a motor (16) that can run off the power from the engine (14) and electricity from the battery (19); a hydraulic pump (18) connected to the motor (16) so as to be driven thereby; and a power divider (17) connected to the engine (14), the generator (15), and the motor (16) such that the power from the engine (14) is distributed to the generator (15) and the motor (16).
