| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
