物料运输车作为铁路养路机械重要的设备之一, 它的行驶安全对铁路建设有重大意义.物料运输车自运行过程中, 如果发动机停止运行, 车辆将丧失制动能力.论文分析了物料运输车制动系统缺陷, 并设计了一套独立的简易电空制动系统, 确保紧急情况下车辆能够实施有效制动.%Material transportation trucks is one of the important equipments of railway maintenance machinery, its driving safety is of great significance to railway construction. The material transportation trucks will lose braking capacity if the engine stops running during the self-running process. This paper analyzes the defect of the brake system of the material transportation trucks and designs an independent simple electro-air braking system to ensure that the vehicle can implement effective braking in emergency situations.
