4×2载货车储气筒容积优化设计

The optimization design ofair reservoir volume for 4×2 truck

储气筒作为气制动车辆制动能量的来源,匹配设计的合理性是影响车辆制动性能的关键因素。结合GB 7258《机动车运行安全技术条件》中对制动系统升压时间的要求,及连续制动性能要求,通过理论计算确定储气筒容积。同时对一款4×2载货车的储气筒容积验证。试验结果表明,理论分析方法所得出的数据与实际测量数据较为接近,证明分析方法可以作为指导气制动车辆储气筒匹配设计的理论依据。

Air reservoir is energy sources of braking of the vehicle equipped with air brake system. Reasonable matching of air reservoir is the key to braking performance of vehicle. Combining with the GB 7258 ＂motor vehicle safety technical conditions＂ in the rise time of the brake system requirements, and continuous braking performance requirements.Through the theoretical calculate and determine the air reservoir volume. Validation for air reservoir volumeof a 4x2 truck at the same time.Result of the verification of targeted test indicate that theoretical data is closer to the actual measurement data,prove that the calculation method can be used as the theoretical basis for matching design of the air reservoir of the vehicle equipped with air brake system.
