Abstract
Description
このタイヤでは、タイヤ骨格部材のクラウン部において、補強層の幅内でかつクラウン部の幅よりも狭い範囲に薄肉部を設けることにより、内圧に対するタイヤの強度を確保しつつ、タイヤを軽量化することができる。
このタイヤでは、薄肉部と一般部との境界部を段差状とすることにより、タイヤ骨格部材のボリュームをより一層低減させて、タイヤを軽量化することができる。
このタイヤでは、境界部がクラウン部の内面側に設けられている場合、クラウン部の外面側を平坦にすることができる。また境界部がクラウン部の外面側に設けられている場合、クラウン部の内面側を平坦にすることができる。
このタイヤでは、薄肉部の厚さが、タイヤ赤道面に向かって漸減するので、クラウン部における薄肉部と、該薄肉部以外の一般部との間の強度変化を緩やかにして、応力集中を抑制し、耐久性を高めることができる。
ここで、薄肉部の範囲が、タイヤ赤道面からタイヤ幅方向外側に、補強層の全幅の1/3を上回ると、補強層のうち内圧付与時に張力が増大する領域に薄肉部が位置することになり、内圧に対するタイヤの強度を十分に確保することが難しくなる。

図3において、本実施形態に係るタイヤ20では、タイヤ骨格部材12のクラウン部22における薄肉部16の厚さが、タイヤ赤道面CLに向かって漸減する。タイヤ赤道面CLから薄肉部16と一般部36との境界部38の位置、即ち薄肉部16の範囲は、一般部36の厚さが薄肉部16に向かって減少し始める位置で特定される。
本実施形態は、上記のように構成されており、以下その作用について説明する。図3において、本実施形態に係るタイヤ20では、薄肉部16の厚さが、タイヤ赤道面CLに向かうに従って減少しているので、クラウン部22における薄肉部16と、該薄肉部16以外の一般部36との間の強度変化を緩やかにして、応力集中を抑制し、耐久性を高めることができる。
上記実施形態において、薄肉部16の範囲が、タイヤ赤道面CLからタイヤ幅方向外側に、補強層14の全幅Wの1/3以内であるものとしたが、これに限られず、全幅Wの1/3を超えていてもよい。
10 タイヤ、12 タイヤ骨格部材、14 補強層、16 薄肉部、18 サイド部、20 タイヤ、22 クラウン部、24 ビード部、30 コード、36 一般部、38 境界部、CL タイヤ赤道面、W 補強層の全幅
