Abstract
The utility model discloses an electric internal-combustion dual-powder locomotive which is provided with two power systems connected in parallel. One power system is a generator driven by a diesel engine, the generator powers a traction motor, and the traction motor is connected with a wheel pair through a transmission device. The other power system is a pantograph, and pantograph acquires direct current or alternating current from a power grid and powers the traction motor through a traction converter. The electric internal-combustion dual-powder locomotive has the advantages that emission pollution is reduced as electric drive is used, the locomotive can operate on an electrified railway, a non-electrified railway and a hybrid crossing railway, allocation efficiency of the locomotive is improved, and time wasted in changing locomotives during a trip is shortened for tourists.
