Hydrostatic-electrical drive e.g. traction drive, has electric motor connected to energy storage and staying in effective connection with hydraulic circuit, where pump stays in drive connection with electric motor

摘要

The drive has an internal combustion engine (1) e.g. diesel engine, and a pump (2) arranged in a hydraulic circuit together with a hydro motor. An electric motor (9) is connected to an energy storage (10) and stays in effective connection with the hydraulic circuit, where the pump stays in drive connection with the electric motor. The engine, pump and the electric motor are arranged coaxial to one another, where the electric motor and the pump are arranged in a common housing.
