  "textContent": "The invention relates to a sound damping device for vehicle wheels, in particular for wheels of rail vehicles, comprising a ring package (2) with at least one open first ring (4) and an open second ring (5), which has a viscoelastic first layer (7) or an open elastic ring interposed between them. [0002] In order to create advantageous construction conditions, it is proposed that at least the first ring (4) in a connection area (31), by way of which at least the first ring (4) can be clamped in a recess of a wheel body (10) of a wheel with the wheel body (10), has a plurality of recesses. [0003] This avoids excessive heating of the ring package (2).",
