Technical difficulty and countermeasure of traction device for C_0-C_0 high-power and heavy-duty freight electric locomotive

The freight electric locomotive is developing toward high-power and heavy-haul,however,C0-C0 high-power and heavy-duty freight electric locomotive is the emphases developing direction.High-power and heavy-haul height electric locomotives require that traction device have a lower traction height and a more strong structure.At the same time,the big traction motor restricts the design dimension of the traction device.This paper analyses how the traction device satisfies the requirement of C0-C0 high-power and heavy-duty freight electric locomotive,based on the traction device of type HXD1B electric locomotive.
