    • Polyblock railway wheel of the type comprising a rim (1), a center part (2) constituted by a hub (22) and a web (6), a damper (5) disposed between the center part (2) and the rim (1), at least one flange (3), and fasteners (7) for fixing the at least one flange (3). The rim (1) comprises in its inner part (9) two connection fillets (10,11) located on opposite sides of the plane of symmetry of the wheel and interconnected in their innermost part, by a generally flat annular strip (12). The damper (5) has a tulip-shaped section. It comprises two rings (19,20) each formed by a ring of elastic polymer material inserted between and bonded to an upper metal flank (31) and a lower metal flank (32); the upper metal flank (31) cooperating with the innermost part (9) of the rim (1), and the lower metal flank (32) cooperating with a flange (3,4).
    • 包括轮辋(1),由轮毂(22)和腹板(6)构成的中心部分(2)的类型的多块铁路车轮,设置在中心部分(2)和轮辋(2)之间的阻尼器(5) 1),至少一个凸缘(3)和用于固定所述至少一个凸缘(3)的紧固件(7)。 边缘(1)在其内部部分(9)中包括两个连接圆角(10,11),该连接圆角位于所述轮子的对称平面的相对侧上,并通过大致平坦的环形条带(12)在其最内部分相互连接。 阻尼器(5)具有郁金香形截面。 它包括两个环(19,20),每个环由弹性聚合物材料环形成,插入在上金属侧面(31)和下金属侧面(32)之间并结合到上金属侧面(31)上。 与边缘(1)的最内部分(9)配合的上金属侧面(31)和与凸缘(3,4)配合的下金属侧面(32)。
