Description
図1、2において、11は高速走行が可能な乗用車用空気入りラジアルタイヤであり、この空気入りタイヤ11は車両の駆動側輪に装着されるとともに、回転方向が規定されている。ここで、車両の駆動側輪とは、走行時、制動力より駆動力が多く作用する車輪をいい、通常はエンジンからの動力が伝達される車軸、リムで、この実施形態では後輪である。
18…カーカス層 23…ベルト層
24、25…ベルトプライ 26、27…ベルトコード
31…ホールド補強層 33…補強コード
38…内側部 39…外側部
43…ベルト強化層 45…補強素子
A…傾斜角 B…内側部の幅
C…外側部の幅 D…ベルト層の幅
S…タイヤ赤道
Claims (5)
- 対をなすビードコア間をトロイダル状に延びるカーカス層と、カーカス層の半径方向外側に配置され、タイヤ赤道Sに対して逆方向に傾斜しているベルトコードが内部に埋設された少なくとも2枚のベルトプライを有するベルト層と、ベルト層の幅方向両端部を包み込むよう折り曲げられ、内部にタイヤ赤道Sに対して傾斜した芳香族ポリアミド繊維からなる補強コードが埋設された一対のホールド補強層と、前記ベルト層より半径方向内側に位置するホールド補強層の内側部にその半径方向内側において積層、または、前記ベルト層より半径方向外側に位置するホールド補強層の外側部にその半径方向外側において積層され、内部にタイヤ赤道Sに実質上平行に延びる補強素子が埋設されたベルト強化層とを備え、車両の駆動側輪に装着される回転方向が規定された空気入りタイヤであって、前記一対のホールド補強層の内側部または外側部のうち、ベルト強化層から離隔した側の内側部または外側部内に埋設されている補強コードが、幅方向内端から折り曲げ位置に向かうに従い回転方向前方に向かうよう傾斜していることを特徴とする空気入りタイヤ。
- 対をなすビードコア間をトロイダル状に延びるカーカス層と、カーカス層の半径方向外側に配置され、タイヤ赤道Sに対して逆方向に傾斜しているベルトコードが内部に埋設された少なくとも2枚のベルトプライを有するベルト層と、ベルト層の幅方向両端部を包み込むよう折り曲げられ、内部にタイヤ赤道Sに対して傾斜した芳香族ポリアミド繊維からなる補強コードが埋設された一対のホールド補強層と、前記ベルト層より半径方向内側に位置するホールド補強層の内側部にその半径方向内側において積層、または、前記ベルト層より半径方向外側に位置するホールド補強層の外側部にその半径方向外側において積層され、内部にタイヤ赤道Sに実質上平行に延びる補強素子が埋設されたベルト強化層とを備え、車両の制動側輪に装着される回転方向が規定された空気入りタイヤであって、前記一対のホールド補強層の内側部または外側部のうち、ベルト強化層から離隔した側の内側部または外側部内に埋設されている補強コードが、幅方向内端から折り曲げ位置に向かうに従い回転方向後方に向かうよう傾斜していることを特徴とする空気入りタイヤ。
