C0-C0轴式大功率货运电力机车牵引装置技术难点分析及对策

目前货运电力机车正朝着重载大功率方向发展，其中C0-C0六轴大功率货运电力机车又是重点发展的车型。大功率货运电力机车要求牵引装置具有低的牵引点高度、更高的结构强度。同时，大功率牵引电机的尺寸大，底部限界的要求也限制了牵引装置的设计空间。文章结合HXolB型电力机车牵引装置，重点分析了该结构是如何满足六轴大功率货运电力机车要求的。

Technical difficulty and countermeasure of traction device for C0-C0 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 HXolB electric locomotive.
