摘　　要：介绍了出口巴基斯坦SDD22型交直流电传动宽轨内燃机车的总体布局、主要技术参数及性能特点,着重阐述了机车柴油机、电气系统、车体及转向架、制动系统、辅助系统的组成及工作原理,分析了开发该机车的主要难点及应对措施、机车主要特点及创新性。机车可以满足印度、阿根廷等国1 676 mm宽轨及高温多风沙运用环境的国家运用,也可以通过换装1 520 mm宽轨、准轨或米轨转向架,推广到中亚、非洲、南美等国。The general arrangement, main technical parameters and performance of SDD22 AC/DC electric drive broad-gauge diesel locomotive exported to Pakistan were introduced, focusing on the composition and working principle of the engine, electrical system, car body and bogie, brake system and auxiliary system. The main diffi cult points, countermeasures, main characteristics and innovation of the locomotive were analyzed. The locomotive could satisfy the requirement of 1676 mm broad-gauge and high-temperature more-sandstorm operation environment such as India, Argentina etc, and with replacing of 1520 mm broad-gauge, standard gauge or meter-gauge bogie, the locomotive could also extended to Middle Asia, Africa, South America etc.
