本文简述了地下汽车的发展过程及使用情况，介绍了国产DQ-18型、UK－12型两种地下汽车（井下运矿车）传动系统设计的构思与方案，扼要给出了两种车型的传动系统设计计算及结果，并通过分析传动系统性能参数的检验结果及使用情况对上述两型地下汽车的传动系统设计进行了评价。
A brief description is given to the development process and appplication of underground trucks, including the domestically made DQ-18 and UK-12 underground trucks (for ore transfer),of which the design conceptions of the drive systems as well as their design calculation results are presented. For the above mentioned two underground trucks, an evaluation is made of their drive designs based on the testing results of their performances and application.
