一种轨道作业车长大坡道持续制动能力的提升研究

Research on improvement of continuous braking capacity on long and steep gradients for a track work vehicle

就一种轨道作业车在长大坡道持续制动能力提升进行阐述,分别提出3种制动能力提升解决方案并讨论了可行性,最终选择采用T211re.4+KB190的液力制动方案,其在原有基础上改动最小,成本最低,可靠性较高。

The paper expounds the improvement of continuous braking capacity on long and steep gradients for a track work vehicle, proposes three solutions to improve braking capacity and discusses the feasibility.Finally,the T211re.4+KB190 hydraulic braking scheme is selected, which has the advantages such as less modification,low cost and high reliability.
