资阳内燃机车工厂在东方红2型液力传动调车内燃机车的基础上,根据运用和生产实践,为了更好适应我国铁路运输和工矿企业日益发展的需要,设计并试制了东方红5型调车小运转用液力传动内燃机车,现已投入批量生产。新机车同东方红2型一样采用一台12V180 ZL型高速柴油机和一套液力传动装置,其结构主要改动之处是: (1)增设了中间齿轮箱,通过改变其传动齿轮比使机车有调车和小运转两种工况,从而扩大了机车的使用范围。
Ziyang diesel locomotive factory in Dongfanghong 2 hydraulic shunting diesel locomotive, based on the application and production practices, in order to better meet the growing needs of China’s railway transport and industrial and mining enterprises, the design and trial production of Dongfanghong 5 Small car with hydraulic drive diesel locomotive, is now put into mass production. The new locomotives, like the Dongfanghong-2, adopt a 12V180 ZL high-speed diesel engine and a hydraulic transmission. The main structural changes are as follows: (1) An intermediate gearbox is added to change the transmission ratio of the locomotive Shunting and small operation of two conditions, thereby expanding the use of locomotives.
