    • A tyre for vehicles includes a carcass structure, a belt structure, and a tread. The tread includes a row of central blocks and a row of intermediate blocks arranged on each side of an equatorial plane of the tyre between a central longitudinal groove formed astride the equatorial plane and a pair of longitudinal lateral grooves. The blocks of the central rows are separated from the blocks of the intermediate rows by circumferential sipes and are circumferentially staggered by a first predetermined quantity relative to the blocks of the intermediate rows. Also, the blocks of the central rows arranged on a first side of the equatorial plane of the tyre are circumferentially staggered by a second predetermined quantity relative to the blocks of the central rows on a second side of the equatorial plane of the tyre.
    • 用于车辆的轮胎包括胎体结构,带束结构和胎面。 胎面包括一列中心块和一排中间块,其布置在横向于赤道平面的中心纵向槽和一对纵向横向槽之间的轮胎的赤道平面的每一侧上。 中央行的块通过周向刀槽花纹与中间行的块分离,并且相对于中间行的块沿周向交错第一预定量。 此外,布置在轮胎的赤道平面的第一侧上的中心列的块相对于轮胎的赤道平面的第二侧上的中心排的块周向交错第二预定量。

    • A tire tread band for medium/heavy duty motor-vehicles having circumferential grooves confining three pairs of respectively center, intermediate and shoulder ribs. Respective tread blocks are defined along the center and intermediate ribs and they are confined by transverse cuts. The center cuts impart a cusp-shaped end conformation and a hollow-shaped end conformation to the respective blocks, and the shapes of said end portions mutually match. The intermediate cuts run in the linear extension of the center cuts to give the respective blocks a rhomboidal configuration. The tire can be alternately associated with a driving axle or a driven axle, by merely reversing its direction of rotation, so that the following results are selectively achieved: an increase in the traction capability by the intermediate blocks or an increase in the directional capability as a result of the mutual wedging between the center blocks at the ground-contacting area.
    • 一种用于中型/重型机动车辆的轮胎胎面带,其具有围绕三对分别的中心,中间和肩部肋骨的周向槽。 相应的胎面花纹块沿中心和中间肋条定义,并且它们被横向切割限制。 中心切口对相应的块赋予尖端形状的端部构造和中空形端部构造,并且所述端部部分的形状相互匹配。 中间切口在中心切口的线性延伸中运行,以使相应的块成为菱形配置。 轮胎可以通过仅使其旋转方向反转来交替地与驱动轴或从动轴相关联,使得选择性地实现以下结果:中间块的牵引能力的增加或定向能力的增加作为 这是在地面接触区域的中心块之间相互楔入的结果。

    • A vehicle wheel tyre includes a carcass structure, a belt structure, and a tread. The tread includes four circumferential grooves and a plurality of transverse grooves that define at least five circumferential rows of blocks, each block approximating a polygon. The longitudinal sides of the blocks are inclined in the same direction at a predetermined angle to the equatorial plane of the tyre. The blocks of each row are circumferentially staggered relative to the blocks of the next row. The blocks of the central row include stiffening means. Profiles of the front sides of the blocks of the central row are the same as the profiles of the rear of the blocks of the central row rotated through 180°. The blocks of the shoulder rows are elastically linked to the blocks of the intermediate rows.
    • 车轮轮胎包括胎体结构,带结构和胎面。 胎面包括四个周向槽和多个限定至少五个圆周行块的横向槽,每个块近似于多边形。 块体的纵向侧面以与轮胎的赤道平面成预定角度的相同方向倾斜。 每行的块相对于下一行的块是周向交错的。 中央行的块包括加强装置。 中央行块的前侧的轮廓与旋转180°的中心排的后部的轮廓相同。 肩部行的块被弹性连接到中间行的块。

    • A method for reducing tire microsliding includes defining a rotation point and rotating a cross section profile about it. A cross section of a radially-external reference profile of a tread band includes a first rectilinear segment near at least one circumferential rib of a first shoulder portion. The first rectilinear segment extends axially outward beyond a corresponding shoulder edge point. A cross section profile of the at least one circumferential rib of the first shoulder portion includes a second rectilinear segment. The rotation point is on the first rectilinear segment, either the corresponding shoulder edge point itself or axially outward of it. The cross section profile of the first rectilinear segment is rotated to define the cross section profile of the second rectilinear segment, so that an axially-inner end of the second rectilinear segment is closer to the carcass structure than an axially-inner end of the first rectilinear segment.
    • 减少轮胎微滑移的方法包括限定旋转点并旋转围绕其的横截面轮廓。 胎面带的径向外部参考轮廓的横截面包括在第一肩部的至少一个周向肋附近的第一直线段。 第一直线段沿轴向向外延伸超过相应的肩部边缘点。 第一肩部的至少一个周向肋的横截面轮廓包括第二直线段。 旋转点在第一直线段上,相应的肩部边缘点本身或轴向向外。 旋转第一直线段的横截面轮廓以限定第二直线段的横截面轮廓,使得第二直线段的轴向内端比第一直线段的轴向内端更靠近胎体结构 直线段
