Description
以下、第一実施形態を図面に基づき説明する。図面において、タイヤ周方向をSで示し、タイヤ軸方向(タイヤ幅方向と読み替えてもよい)を矢印Wで示し、タイヤ径方向を矢印Rで示している。タイヤ軸方向とは、タイヤ回転軸と平行な方向を意味する。
カーカス16のクラウン部の外側、言い換えればカーカス16のタイヤ径方向外側には、ベルト層26が配置されており、ベルト層26はカーカス16の外周面に密着している。
図2から図6は、本実施形態に係るベルト層構成部材の製造方法を示す図であり、ベルト層構成部材60は(図5参照)、タイヤケース25の外周に設けられベルト層26を構成する部材である。
本実施形態のタイヤ10において、タイヤ骨格部材であるタイヤケース25の外周に設けられたベルト層26は、螺旋状に巻かれた補強コード30を囲むとともにタイヤ軸方向(タイヤ幅方向)の全域に渡って一体的に被覆する樹脂層50を備えている。
図7から図9は、第二実施形態に係るベルト層構成部材の製造方法を示す図であり、第一実施形態と同一又は同等部分については、同符号を付して説明を割愛するとともに、異なる部分についてのみ説明する。
なお、本実施形態では、溝90Bを有した帯状部材90を例に挙げて説明するが、これに限定されるものではなく、溝90Bを有しない帯状部材90を用いてもよい。
なお、本実施形態では、補強コード30の上に帯状部材90を巻き付けた後に、加熱ノズル92から熱風Hを吹き付け、巻き付けた帯状部材90全体を溶融したが、これに限定されるものではない。例えば、補強コード30の上に帯状部材90を巻き付けながら、この帯状部材90に加熱ノズル92からの熱風Hを吹き付けて帯状部材90を溶融してもよい。
図10から図12は、第三実施形態に係るベルト層構成部材の製造方法を示す図であり、第一実施形態と同一又は同等部分については、同符号を付して説明を割愛するとともに、異なる部分についてのみ説明する。
