| 中文摘要: |
| 介绍12.00R24全新混合型全钢载重子午线轮胎的设计。结构设计：外直径 1 216 mm，断面宽 310 mm，行驶面宽度 240 mm，行驶面弧度高 7 mm，胎圈着合直径 613.5 mm，胎圈着合宽度 230 mm，断面水平轴位置（H1/H2） 1.08，采用折线型花纹沟设计，花纹深度 15 mm，花纹周节数 63，花纹饱和度 76.8%。施工设计：胎面采用两方两块设计，胎体采用3×0.24/9×0.225CCHT紧密型高强度钢丝帘线，1#，2#，3#带束层采用0.37＋6×0.32ST超高强度钢丝帘线，4#带束层采用5×0.35HI高抗冲击钢丝帘线，采用胶囊三鼓一次法成型机成型，热板充氮全自动液压硫化机硫化。成品轮胎性能试验结果表明：轮胎的充气外缘尺寸、强度性能、耐久性能和高速性能均符合相应的国家或企业标准要求。 |
| 英文摘要: |
| The design of 12.00R24 new hybrid track and bus radial tire was described.In the structure design，the following parameters were taken ：overall diameter 1 216 mm，cross-section width 310 mm，width of running surface 240 mm，arc height of running surface 7 mm，bead diameter at rim seat 613.5 mm, bead width at rim seat 230 mm，maximum width position of cross-setion（H1/H2） 1.08，using zigzag groove design，the pattern depth 15 mm，the pattern perimeter number 63，and the block/total ratio 23.2%∶76.8%.In the construction design，the following processes were taken：the tread adopted two sides and two pieces，the carcass adopted 3×0.24/9×0.225CCHT compact high-strength steel cords，1#，2# and 3# belt layers adopted 0.37+6×0.32ST super high strength steel cord，4# belt adopted 5×0.35HI high impact steel cord，using capsule three-drum one-step building machine to build tire and curing tire by hot plate nitrogen-filled automatic hydraulic curing machine.The test results of the finished tire showed that，the inflated peripheral dimension，strength performance，durability and high-speed performance all met the requirements of national or corporate standards. |
