  • Patent number: 10086646
    Abstract: A wheel for a rail vehicle has a wheel tire (1) with a ridge (9) formed on the inner circumference of the wheel tire (1), a wheel body (3) with a ring flange (11) formed on the outer circumference and running radially outward, and a clamp ring (5) attached to the wheel body (3) via a fastening means (13), on a side face opposite the ring flange (11). Damping means formed as at least two separate circular ring segments (7) extend between the clamp ring (5) and the circumferential ridge and between the circumferential ridge (9) of the wheel tire (1) and the ring flange in the circumferential direction of the wheel. On at least one side, the circular ring segments (7) have at least two centering cams (19) meshing into corresponding recesses (21). The circular segments (7) have an elastomer core enclosed by metal sheet segments (17).

  • Patent number: 6659015
    Abstract: The invention relates to an idler wheel arrangement for rail vehicles, consisting of a wheel (2) rotatably mounted on an axle stub (4) of an axle (6), in particular of a cranked straddle axle, and having an inside (12) facing the axle (6) and an opposite outside (16) and of holding means for three functional devices, specifically for an earth-contact arrangement (18), a transmitter arrangement (20) of an anti-slip device and a braking device (22). The holding means having a carrier element (24) fixedly connected on the end face to the axle stub (4) on the outside (16) of the wheel (2). The carrier element (24) has reception means for fixed components (18a, 20a, 22a) of all three functional devices (18, 20, 22), the wheel (2) being assigned reception means for correspondingly associated components (18b, 20b, 22b), rotating with the wheel (2), of the three functional devices (18, 20, 22), in adaptation to the arrangement of the fixed components (18a, 20a, 22a).
