    摘要: 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).
