Self-ventilating railway driving mechanism for local-service rail cars, has a power converter, a self-cooled electric motor and an air-conducting channel

摘要

A self-ventilating railway driving mechanism (2) has a power converter (4) fitted with a clearance between it and a self-cooled electric motor (6) and an air-conducting channel (8) that links the power converter to the self-cooled motor so as to supply cooling air. The air-conducting channel has areas (10) to compensate for movement.
