Research on Two Axis Pure Electric Heavy Rail Vehicles
Two axle heavy-duty rail cars are important traction equipment in the construction process of urban rail transit track laying.Currently,diesel engines are mainly used as the power source,and noise and exhaust emissions are generated during operation.To meet the increasing environmental requirements,a two axle pure electric heavy-duty rail car powered by a lithium battery pack and a permanent magnet AC transmission system was studied.There is no noise or exhaust emissions during operation.At the same time,the application of mature locomotive unit brakes as the entire vehicle braking actuator results in higher braking efficiency and reliability,which can adapt to environmental requirements in track laying construction scenarios.
