1. A wheel for a rail vehicle, comprising:

  • a tyre (1) having a circumferential abutment (9) formed on the inner periphery of the tyre (1) and extending in the direction of the axis of rotation (X-X) of the wheel;

    a wheel main body (3) having an annular flange (11) formed on the outer periphery and on the axial end side of the wheel main body (3) and extending radially outward; and

    a clamping ring (5) which is arranged on the wheel body (3) on the end side opposite the annular flange (11) in a force-fitting and/or form-fitting manner by means of a fastening element (13), wherein a damping element is arranged between the clamping ring (5) and the circumferential abutment (9) of the tire (1) and between the circumferential abutment (9) of the tire (1) and the annular flange (11) of the wheel body (3), respectively, characterized in that,the dampers are each designed as at least two separate ring segments (7) extending in the direction of rotation of the wheel, the ring segments (7) extending through the ring segments of the wheel at a central angle (γ

    ) of at least 30 °

    to at most 180 °

    , the ring segments (7) having at least on one side at least on contact surfaces at least two centering cams (19) extending in the axial direction and spaced apart in the direction of rotation, which engage in a form-fitting manner on the circumferential lugs (9) of the tire (1) and on the annular flange (11) of the wheel body (3) or in corresponding recesses (21) of the clamping ring (5), the ring segments (7) having an elastomer material as an inner core (15), the inner core (15) of the ring segments (7) being laminated at least on their contact surfaces abutting against the circumferential lugs (9) of the tire (1) and against the clamping ring (5) or the annular flange (11) of the wheel body (3) The section (17) is surrounded, wherein a radius bead (25) that is recessed inward into the elastomer material and surrounds the centering cam (19) is formed at the transition of the basic shape of the section (17) to the centering cam (19) of the ring section (7).
