摘　　要：介绍绿色低碳聚氨酯非充气轮胎的设计与制造。分析节能机理;针对现有非充气轮胎节能性差的问题,为提高真圆度,该非充气轮胎采用胎体、轮辋、错位八字形的燕尾凸起结构、帘线、轮辐支撑结构组成,胎体采用聚氨酯/橡胶粉复合材料,外模具与带凸起结构的轮毂组装,轮毂与胎体一体浇注成型。该非充气轮胎用聚氨酯材料替代橡胶材料,其回收利用率高;高强度胎体可以保证轮胎的真圆度,降低轮胎的油耗和减少磨损,延长轮胎的使用寿命。The design and manufacture of the green and low-carbon polyurethane non-pneumatic tire were introduced,and the energy saving mechanism was analyzed.Aiming at the problem of poor energy saving of existing non-pneumatic tires,in order to improve the roundness,this non-pneumatic tire was composed of the carcass,rim,dovetail convex structure with misalignment of splayed formation,cord,and spoke support structure.The carcass was made of polyurethane/rubber powder composite material,the outer mold was assembled with the wheel hub with a convex structure,and the hub and carcass were molded together using integrated casting process.Since polyurethane material was used for this non-pneumatic tire instead of rubber material,the tire had a high recycling rate.At the same time,high strength carcass could ensure the roundness of the tire,reduce fuel consumption and wear of the tire,and extend the service life of the tire.
