A vehicle pneumatic tire, and a system and method for producing the vehicle pneumatic tire, having a belt composed of at least one steel cord belt layer (11, 12) surrounding the circumference of the tire, and a strap radially supported on the belt on the outside over the circumference of the tire. The vehicle pneumatic tire strap is composed of a rubber strip (20) comprising at least one reinforcing fiber cord (24). The rubber strip (20) is wound around the belt of the vehicle pneumatic tire at least from one axial end of the belt to at least the other axial end of the belt in a winding direction with respect to the circumferential direction of the vehicle pneumatic tire, the ratio of the component of the winding direction in the axial direction A to the component of the winding direction in the circumferential direction along the rubber strip is less than 0.01 and does not vary by more than 2% over at least 70% of the width of the belt in the axial direction A. At each circumferential position, the pitch of two adjacent cords (24, 24 ') of two adjacent portions of the wound rubber strip does not vary by more than 5% compared to the pitch of cords in the rubber strip. The cords (24) in the strap are subjected to a tension of at least 3 N/mm2 over at least 25% of the width of the belt in the axial direction A.

    一种车辆充气轮胎,以及一种用于生产该车辆充气轮胎的系统和方法,该车辆充气轮胎具有带束和箍带,该带束由环绕轮胎圆周的至少一个钢帘线带束层(11,12)构成,该箍带在整个轮胎圆周上在外部径向地支承在带束上。车辆充气轮胎箍带由包含了至少一个加强纤维帘线(24)的橡胶条(20)构成。该橡胶条(20)在相对于车辆充气轮胎的周向方向的缠绕方向上至少从带束的一个轴向端部到带束的至少另一个轴向端部缠绕在车辆充气轮胎的带束周围,其中,缠绕方向在轴线方向A上的分量与缠绕方向在沿着橡胶条的周向方向上的分量之间的比率小于0.01,并且在带束在轴线方向A上的宽度的至少70%上不会变化超过2%。在每个周向位置处,缠绕的橡胶条的两个相邻部分的两个相邻帘线(24,24')的间距与橡胶条中的帘线的间距相比不会变化超过5%。箍带中的帘线(24)在带束在轴线方向A上的宽度的至少25%上受到至少3N/mm2的张力。
