摘要： An intelligent tire, including a tire body (1), a sheet-shaped conductive polymer sensor (5), a micro control unit (6), an RF unit (7), an upper computer (8), and an RF circuit (9). The sheet-shaped conductive polymer sensor (5) is affixed to an inner liner layer (4) at a middle portion of a tire crown. One end of the sheet-shaped conductive polymer sensor (5) is connected to the micro control unit (6) through the RF unit (7), and the other end of the sheet-shaped conductive polymer sensor (5) is connected to the upper computer (8) through the RF circuit (9). A processor (8-6) is electrically connected to a power supply module (8-1), and the processor is connected to and controls a display screen (8-3) and an audible alarm (8-4). A communication port (8-2) is interconnected to the processor (8-6). The intelligent tire is mainly designed for early warning of dangerous tire conditions. The state of the tire is comprehensively determined by matching or combining the strain amplitude of the tire crown and an operating temperature with a fitting function. The strain amplitude and the operating temperature can be simultaneously obtained by using the single conductive polymer sensor, so as to provide the early warning of various dangerous conditions of the tire. Moreover, the sheet-shaped conductive polymer sensor has a low cost and is readily popularized.

摘要： Provided is a method of using a corrugated zero-degree belt (14) to manufacture a tire. A belt ply structure comprises a No. 1 belt ply (11), a No. 2 belt ply (12), a No. 3 belt ply (13), a corrugated zero-degree belt (14), and a shoulder wedge (15). In a belt ply structure of an all-steel radial tire, a zero-degree belt has a halved density and is wound in two turns. The upper ply and the lower ply are arranged in a staggered manner, thereby forming a single belt. Since each steel cord is wound in two turns, a strength problem of a joint portion is solved. The belt ply structure realizes restraining and fastening functions of a zero-degree belt ply while reducing costs and a weight of a tire. What is more important is that the entire belt ply is flat and smooth and has a consistent thickness. The belt ply structure can improve high-speed performance and abrasion resistance of a tire. Moreover, circumferential distribution of a framework material is more uniform, thereby enhancing uniformity of the tire and driving comfort.
