具有子午線胎體之自行車輪胎Bicycle tire with radial carcass

本創作係與自行車輪胎有關，特別是關於一種具有子午線胎體之自行車輪胎。This creation is related to bicycle tires, especially for a bicycle tire with a radial carcass.

習用之輪胎大致上可區分為具有斜交式胎體之結構及具有子午線胎體之結構，斜交式胎體之織線係與輪胎之赤道線有非0度或90度之夾角，該夾角大多為30~60度，而子午線胎體之織線則與輪胎之赤道線垂直。相較於斜交式胎體，子午線胎體具有較好的曲撓性及柔軟度，使得輪胎在平坦道路上舒適性較佳，子午線胎體大多會搭配高剛性環帶，其織線與輪胎之赤道線的夾角較小，大約為20~40度，如此可使輪胎加速性更好且使用壽命更高，但在不平整路上的舒適性較差。現今一般道路都相當平整，因此高速車輛（例如機車、汽車、遊覽車等等）大多採用具有子午線胎體之輪胎，以兼具舒適、加速性高及使用壽命高等優點。The conventional tire can be roughly divided into a structure having a skew type carcass and a structure having a radial carcass, and the skew line of the skew type carcass has an angle other than 0 or 90 degrees with the equator of the tire, the angle Mostly 30 to 60 degrees, and the radial line of the carcass is perpendicular to the equator of the tire. Compared with the skew type carcass, the radial carcass has better flexibility and softness, which makes the tires more comfortable on flat roads. Most of the radial carcasses are matched with high-rigidity belts, and their weaving lines and tires. The angle of the equator line is small, about 20 to 40 degrees, which makes the tire more accelerating and has a longer service life, but the comfort on the uneven road is poor. Today's general roads are fairly flat, so high-speed vehicles (such as locomotives, cars, tour buses, etc.) mostly use tires with radial carcasses to combine comfort, acceleration and service life.

由於一般子午線胎體柔軟度過高，導致輪胎轉彎性不佳，且胎側容易被刺破，高剛性環帶又會導致輪胎過重，不符合自行車之輕量化需求，因此，自行車輪胎大多採用斜交式胎體。但採用斜交式胎體之輪胎缺少了採用子午線胎體之輪胎所特有的高舒適度、高加速性及高使用壽命，不符合近年自行車業界追求之高運動性能。Because the softness of the general meridian carcass is too high, the tire turns poorly, and the sidewall is easily pierced. The high-rigidity ring will cause the tire to be too heavy and does not meet the lightweight requirements of the bicycle. Therefore, most bicycle tires are inclined. Cross-type carcass. However, the tire with the skew type carcass lacks the high comfort, high acceleration and long service life unique to the tire using the radial carcass, and does not meet the high sports performance pursued by the bicycle industry in recent years.

雖然市面上有些自行車輪胎之胎體係設計成類似於子午線胎體，其織線與輪胎赤道線的夾角約為75~85度，但並非國際定義的子午線胎體，不但仍欠缺子午線胎體性能，亦弱化了原有斜交式胎體的優點。為了配合自行車業界追求輕量化及高運動性能之目標，習用之自行車輪胎仍需在結構上有所突破，以滿足高性能要求。Although some bicycle tire systems on the market are designed to resemble a radial carcass, the angle between the woven line and the tire equator line is about 75-85 degrees, but it is not an internationally defined radial carcass, not only lacking the meridian carcass performance, It also weakens the advantages of the original skew type carcass. In order to meet the goal of the bicycle industry to pursue lightweight and high sports performance, the bicycle tires still need to be structurally breakthrough to meet the high performance requirements.

有鑑於上述缺失，本創作之主要目的在於提供一種具有子午線胎體之自行車輪胎，係兼具輕量化、高舒適度、高加速性及高使用壽命。In view of the above-mentioned shortcomings, the main purpose of the present invention is to provide a bicycle tire having a radial carcass, which is lightweight, high in comfort, high in acceleration, and high in service life.
